Arnaud et Emmanuel discutent des nouvelles de ce mois. On y parle intégrité de JVM, fetch size de JDBC, MCP, de prompt engineering, de DeepSeek bien sûr mais aussi de Maven 4 et des proxy de répository Maven. Et d'autres choses encore, bonne lecture. Enregistré le 7 février 2025 Téléchargement de l'épisode LesCastCodeurs-Episode-322.mp3 ou en vidéo sur YouTube. News Langages Les evolutions de la JVM pour augmenter l'intégrité https://inside.java/2025/01/03/evolving-default-integrity/ un article sur les raisons pour lesquelles les editeurs de frameworks et les utilisateurs s'arrachent les cheveux et vont continuer garantir l'integrite du code et des données en enlevant des APIs existantes historiquemnt agents dynamiques, setAccessible, Unsafe, JNI Article expliques les risques percus par les mainteneurs de la JVM Franchement c'est un peu leg sur les causes l'article, auto propagande JavaScript Temporal, enfin une API propre et moderne pour gérer les dates en JS https://developer.mozilla.org/en-US/blog/javascript-temporal-is-coming/ JavaScript Temporal est un nouvel objet conçu pour remplacer l'objet Date, qui présente des défauts. Il résout des problèmes tels que le manque de prise en charge des fuseaux horaires et la mutabilité. Temporal introduit des concepts tels que les instants, les heures civiles et les durées. Il fournit des classes pour gérer diverses représentations de date/heure, y compris celles qui tiennent compte du fuseau horaire et celles qui n'en tiennent pas compte. Temporal simplifie l'utilisation de différents calendriers (par exemple, chinois, hébreu). Il comprend des méthodes pour les comparaisons, les conversions et le formatage des dates et des heures. La prise en charge par les navigateurs est expérimentale, Firefox Nightly ayant l'implémentation la plus aboutie. Un polyfill est disponible pour essayer Temporal dans n'importe quel navigateur. Librairies Un article sur les fetch size du JDBC et les impacts sur vos applications https://in.relation.to/2025/01/24/jdbc-fetch-size/ qui connait la valeur fetch size par default de son driver? en fonction de vos use cases, ca peut etre devastateur exemple d'une appli qui retourne 12 lignes et un fetch size de oracle a 10, 2 a/r pour rien et si c'est 50 lignres retournées la base de donnée est le facteur limitant, pas Java donc monter sont fetch size est avantageux, on utilise la memoire de Java pour eviter la latence Quarkus annouce les MCP servers project pour collecter les servier MCP en Java https://quarkus.io/blog/introducing-mcp-servers/ MCP d'Anthropic introspecteur de bases JDBC lecteur de filke system Dessine en Java FX demarrables facilement avec jbang et testes avec claude desktop, goose et mcp-cli permet d'utliser le pouvoir des librarires Java de votre IA d'ailleurs Spring a la version 0.6 de leur support MCP https://spring.io/blog/2025/01/23/spring-ai-mcp-0 Infrastructure Apache Flink sur Kibernetes https://www.decodable.co/blog/get-running-with-apache-flink-on-kubernetes-2 un article tres complet ejn deux parties sur l'installation de Flink sur Kubernetes installation, setup mais aussi le checkpointing, la HA, l'observablité Data et Intelligence Artificielle 10 techniques de prompt engineering https://medium.com/google-cloud/10-prompt-engineering-techniques-every-beginner-should-know-bf6c195916c7 Si vous voulez aller plus loin, l'article référence un très bon livre blanc sur le prompt engineering https://www.kaggle.com/whitepaper-prompt-engineering Les techniques évoquées : Zero-Shot Prompting: On demande directement à l'IA de répondre à une question sans lui fournir d'exemple préalable. C'est comme si on posait une question à une personne sans lui donner de contexte. Few-Shot Prompting: On donne à l'IA un ou plusieurs exemples de la tâche qu'on souhaite qu'elle accomplisse. C'est comme montrer à quelqu'un comment faire quelque chose avant de lui demander de le faire. System Prompting: On définit le contexte général et le but de la tâche pour l'IA. C'est comme donner à l'IA des instructions générales sur ce qu'elle doit faire. Role Prompting: On attribue un rôle spécifique à l'IA (enseignant, journaliste, etc.). C'est comme demander à quelqu'un de jouer un rôle spécifique. Contextual Prompting: On fournit des informations supplémentaires ou un contexte pour la tâche. C'est comme donner à quelqu'un toutes les informations nécessaires pour répondre à une question. Step-Back Prompting: On pose d'abord une question générale, puis on utilise la réponse pour poser une question plus spécifique. C'est comme poser une question ouverte avant de poser une question plus fermée. Chain-of-Thought Prompting: On demande à l'IA de montrer étape par étape comment elle arrive à sa conclusion. C'est comme demander à quelqu'un d'expliquer son raisonnement. Self-Consistency Prompting: On pose plusieurs fois la même question à l'IA et on compare les réponses pour trouver la plus cohérente. C'est comme vérifier une réponse en la posant sous différentes formes. Tree-of-Thoughts Prompting: On permet à l'IA d'explorer plusieurs chemins de raisonnement en même temps. C'est comme considérer toutes les options possibles avant de prendre une décision. ReAct Prompting: On permet à l'IA d'interagir avec des outils externes pour résoudre des problèmes complexes. C'est comme donner à quelqu'un les outils nécessaires pour résoudre un problème. Les patterns GenAI the thoughtworks https://martinfowler.com/articles/gen-ai-patterns/ tres introductif et pre RAG le direct prompt qui est un appel direct au LLM: limitations de connaissance et de controle de l'experience eval: evaluer la sortie d'un LLM avec plusieurs techniques mais fondamentalement une fonction qui prend la demande, la reponse et donc un score numerique evaluation via un LLM (le meme ou un autre), ou evaluation humaine tourner les evaluations a partir de la chaine de build amis aussi en live vu que les LLMs puvent evoluer. Decrit les embedding notament d'image amis aussi de texte avec la notion de contexte DeepSeek et la fin de la domination de NVidia https://youtubetranscriptoptimizer.com/blog/05_the_short_case_for_nvda un article sur les raisons pour lesquelles NVIDIA va se faire cahllengert sur ses marges 90% de marge quand meme parce que les plus gros GPU et CUDA qui est proprio mais des approches ardware alternatives existent qui sont plus efficientes (TPU et gros waffle) Google, MS et d'autres construisent leurs GPU alternatifs CUDA devient de moins en moins le linga franca avec l'investissement sur des langages intermediares alternatifs par Apple, Google OpenAI etc L'article parle de DeepSkeek qui est venu mettre une baffe dans le monde des LLMs Ils ont construit un competiteur a gpt4o et o1 avec 5M de dollars et des capacites de raisonnements impressionnant la cles c'etait beaucoup de trick d'optimisation mais le plus gros est d'avoir des poids de neurores sur 8 bits vs 32 pour les autres. et donc de quatizer au fil de l'eau et au moment de l'entrainement beaucoup de reinforcemnt learning innovatifs aussi et des Mixture of Expert donc ~50x moins chers que OpenAI Donc plus besoin de GPU qui on des tonnes de vRAM ah et DeepSeek est open source un article de semianalytics change un peu le narratif le papier de DeepSkeek en dit long via ses omissions par ensemple les 6M c'est juste l'inference en GPU, pas les couts de recherches et divers trials et erreurs en comparaison Claude Sonnet a coute 10M en infererence DeepSeek a beaucoup de CPU pre ban et ceratins post bans evalués a 5 Milliards en investissement. leurs avancées et leur ouverture reste extremement interessante Une intro à Apache Iceberg http://blog.ippon.fr/2025/01/17/la-revolution-des-donnees-lavenement-des-lakehouses-avec-apache-iceberg/ issue des limites du data lake. non structuré et des Data Warehouses aux limites en diversite de données et de volume entrent les lakehouse Et particulierement Apache Iceberg issue de Netflix gestion de schema mais flexible notion de copy en write vs merge on read en fonction de besoins garantie atomicite, coherence, isoliation et durabilite notion de time travel et rollback partitions cachées (qui abstraient la partition et ses transfos) et evolution de partitions compatbile avec les moteurs de calcul comme spark, trino, flink etc explique la structure des metadonnées et des données Guillaume s'amuse à générer des histoires courtes de Science-Fiction en programmant des Agents IA avec LangChain4j et aussi avec des workflows https://glaforge.dev/posts/2025/01/27/an-ai-agent-to-generate-short-scifi-stories/ https://glaforge.dev/posts/2025/01/31/a-genai-agent-with-a-real-workflow/ Création d'un générateur automatisé de nouvelles de science-fiction à l'aide de Gemini et Imagen en Java, LangChain4j, sur Google Cloud. Le système génère chaque nuit des histoires, complétées par des illustrations créées par le modèle Imagen 3, et les publie sur un site Web. Une étape d'auto-réflexion utilise Gemini pour sélectionner la meilleure image pour chaque chapitre. L'agent utilise un workflow explicite, drivé par le code Java, où les étapes sont prédéfinies dans le code, plutôt que de s'appuyer sur une planification basée sur LLM. Le code est disponible sur GitHub et l'application est déployée sur Google Cloud. L'article oppose les agents de workflow explicites aux agents autonomes, en soulignant les compromis de chaque approche. Car parfois, les Agent IA autonomes qui gèrent leur propre planning hallucinent un peu trop et n'établissent pas un plan correctement, ou ne le suive pas comme il faut, voire hallucine des “function call”. Le projet utilise Cloud Build, le Cloud Run jobs, Cloud Scheduler, Firestore comme base de données, et Firebase pour le déploiement et l'automatisation du frontend. Dans le deuxième article, L'approche est différente, Guillaume utilise un outil de Workflow, plutôt que de diriger le planning avec du code Java. L'approche impérative utilise du code Java explicite pour orchestrer le workflow, offrant ainsi un contrôle et une parallélisation précis. L'approche déclarative utilise un fichier YAML pour définir le workflow, en spécifiant les étapes, les entrées, les sorties et l'ordre d'exécution. Le workflow comprend les étapes permettant de générer une histoire avec Gemini 2, de créer une invite d'image, de générer des images avec Imagen 3 et d'enregistrer le résultat dans Cloud Firestore (base de donnée NoSQL). Les principaux avantages de l'approche impérative sont un contrôle précis, une parallélisation explicite et des outils de programmation familiers. Les principaux avantages de l'approche déclarative sont des définitions de workflow peut-être plus faciles à comprendre (même si c'est un YAML, berk !) la visualisation, l'évolutivité et une maintenance simplifiée (on peut juste changer le YAML dans la console, comme au bon vieux temps du PHP en prod). Les inconvénients de l'approche impérative incluent le besoin de connaissances en programmation, les défis potentiels en matière de maintenance et la gestion des conteneurs. Les inconvénients de l'approche déclarative incluent une création YAML pénible, un contrôle de parallélisation limité, l'absence d'émulateur local et un débogage moins intuitif. Le choix entre les approches dépend des exigences du projet, la déclarative étant adaptée aux workflows plus simples. L'article conclut que la planification déclarative peut aider les agents IA à rester concentrés et prévisibles. Outillage Vulnérabilité des proxy Maven https://github.blog/security/vulnerability-research/attacks-on-maven-proxy-repositories/ Quelque soit le langage, la techno, il est hautement conseillé de mettre en place des gestionnaires de repositories en tant que proxy pour mieux contrôler les dépendances qui contribuent à la création de vos produits Michael Stepankin de l'équipe GitHub Security Lab a cherché a savoir si ces derniers ne sont pas aussi sources de vulnérabilité en étudiant quelques CVEs sur des produits comme JFrog Artifactory, Sonatype Nexus, et Reposilite Certaines failles viennent de la UI des produits qui permettent d'afficher les artifacts (ex: mettez un JS dans un fichier POM) et même de naviguer dedans (ex: voir le contenu d'un jar / zip et on exploite l'API pour lire, voir modifier des fichiers du serveur en dehors des archives) Les artifacts peuvent aussi être compromis en jouant sur les paramètres propriétaires des URLs ou en jouant sur le nomage avec les encodings. Bref, rien n'est simple ni niveau. Tout système rajoute de la compléxité et il est important de les tenir à mettre à jour. Il faut surveiller activement sa chaine de distribution via différents moyens et ne pas tout miser sur le repository manager. L'auteur a fait une présentation sur le sujet : https://www.youtube.com/watch?v=0Z_QXtk0Z54 Apache Maven 4… Bientôt, c'est promis …. qu'est ce qu'il y aura dedans ? https://gnodet.github.io/maven4-presentation/ Et aussi https://github.com/Bukama/MavenStuff/blob/main/Maven4/whatsnewinmaven4.md Apache Maven 4 Doucement mais surement …. c'est le principe d'un projet Maven 4.0.0-rc-2 est dispo (Dec 2024). Maven a plus de 20 ans et est largement utilisé dans l'écosystème Java. La compatibilité ascendante a toujours été une priorité, mais elle a limité la flexibilité. Maven 4 introduit des changements significatifs, notamment un nouveau schéma de construction et des améliorations du code. Changements du POM Séparation du Build-POM et du Consumer-POM : Build-POM : Contient des informations propres à la construction (ex. plugins, configurations). Consumer-POM : Contient uniquement les informations nécessaires aux consommateurs d'artefacts (ex. dépendances). Nouveau Modèle Version 4.1.0 : Utilisé uniquement pour le Build-POM, alors que le Consumer-POM reste en 4.0.0 pour la compatibilité. Introduit de nouveaux éléments et en marque certains comme obsolètes. Modules renommés en sous-projets : “Modules” devient “Sous-projets” pour éviter la confusion avec les Modules Java. L'élément remplace (qui reste pris en charge). Nouveau type de packaging : “bom” (Bill of Materials) : Différencie les POMs parents et les BOMs de gestion des dépendances. Prend en charge les exclusions et les imports basés sur les classifiers. Déclaration explicite du répertoire racine : permet de définir explicitement le répertoire racine du projet. Élimine toute ambiguïté sur la localisation des racines de projet. Nouvelles variables de répertoire : ${project.rootDirectory}, ${session.topDirectory} et ${session.rootDirectory} pour une meilleure gestion des chemins. Remplace les anciennes solutions non officielles et variables internes obsolètes. Prise en charge de syntaxes alternatives pour le POM Introduction de ModelParser SPI permettant des syntaxes alternatives pour le POM. Apache Maven Hocon Extension est un exemple précoce de cette fonctionnalité. Améliorations pour les sous-projets Versioning automatique des parents Il n'est plus nécessaire de définir la version des parents dans chaque sous-projet. Fonctionne avec le modèle de version 4.1.0 et s'étend aux dépendances internes au projet. Support complet des variables compatibles CI Le Flatten Maven Plugin n'est plus requis. Prend en charge les variables comme ${revision} pour le versioning. Peut être défini via maven.config ou la ligne de commande (mvn verify -Drevision=4.0.1). Améliorations et corrections du Reactor Correction de bug : Gestion améliorée de --also-make lors de la reprise des builds. Nouvelle option --resume (-r) pour redémarrer à partir du dernier sous-projet en échec. Les sous-projets déjà construits avec succès sont ignorés lors de la reprise. Constructions sensibles aux sous-dossiers : Possibilité d'exécuter des outils sur des sous-projets sélectionnés uniquement. Recommandation : Utiliser mvn verify plutôt que mvn clean install. Autres Améliorations Timestamps cohérents pour tous les sous-projets dans les archives packagées. Déploiement amélioré : Le déploiement ne se produit que si tous les sous-projets sont construits avec succès. Changements de workflow, cycle de vie et exécution Java 17 requis pour exécuter Maven Java 17 est le JDK minimum requis pour exécuter Maven 4. Les anciennes versions de Java peuvent toujours être ciblées pour la compilation via Maven Toolchains. Java 17 a été préféré à Java 21 en raison d'un support à long terme plus étendu. Mise à jour des plugins et maintenance des applications Suppression des fonctionnalités obsolètes (ex. Plexus Containers, expressions ${pom.}). Mise à jour du Super POM, modifiant les versions par défaut des plugins. Les builds peuvent se comporter différemment ; définissez des versions fixes des plugins pour éviter les changements inattendus. Maven 4 affiche un avertissement si des versions par défaut sont utilisées. Nouveau paramètre “Fail on Severity” Le build peut échouer si des messages de log atteignent un niveau de gravité spécifique (ex. WARN). Utilisable via --fail-on-severity WARN ou -fos WARN. Maven Shell (mvnsh) Chaque exécution de mvn nécessitait auparavant un redémarrage complet de Java/Maven. Maven 4 introduit Maven Shell (mvnsh), qui maintient un processus Maven résident unique ouvert pour plusieurs commandes. Améliore la performance et réduit les temps de build. Alternative : Utilisez Maven Daemon (mvnd), qui gère un pool de processus Maven résidents.

During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:26 Lois: Hello and welcome to the Oracle University Podcast. I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Principal Technical Editor. Nikita: Hi everyone! Last week, we had quite a power-packed episode. We discussed the 23ai new feature for Automatic SQL Plan Management. We also looked at the 23ai automatic feature that enhances SecureFiles LOB Write Performance as well as the update to Wide Columns. 00:59 Lois: Yeah, and in today's episode, we will look at True Cache, another 23ai new feature. To tell us all about it, we have Bill Millar back with us. Bill is a Senior Principal Database & MySQL Instructor with Oracle University. We'll ask Bill to give us an overview of True Cache, talk about its configuration and deployment, and discuss how to apply True Cache to our applications. Nikita: To kick things off, Bill, can you give us a high-level overview of what True Cache is? How does it differ from other caching solutions like Redis or Memcached? 01:35 Bill: True Cache is an in-memory cache. It is read-only. True Cache is deployed in front of a primary database, and it is automatically managed. It keeps the most frequently accessed data in the cache, and it keeps the cache consistent with the primary database. They call it diskless, but it's not. It does require some space for SP file, redo logs, control files, and such. But it's very similar to Active Data Guard. The queries can be offloaded to the True Cache for faster query response. And the data in the query cache is consistent. Unlike other mid-tier caches like Redis or Memcached, a query to the True Cache returns only committed data, and the data is always consistent. It's secure. Why? Because we implement our Oracle database security policies and you can control access to the cache. 02:33 Lois: So, why should we use True Cache? Bill: Improve application performance without having to rewrite any applications. That can save considerable amount of time, effort, and expense. Reduces the application response time. So the closer the True Cache is to the application, the faster the response. Now, you do need a large amount of memory. We're talking memory here. It's an in-memory storage area, and depending on how you configure it, you can have it shared, you can have it divided. We mentioned it's automatically maintained. So there's no application changes required, and it is transparent to the application. Again, simplifies that development and maintenance. 03:15 Nikita: How does it impact application performance, and what kind of scenarios would benefit the most from implementing True Cache? Bill: So at a high-level view, True Cache or primary database, the application configuration serves as other things that are going to decide where is it going to query the data from, from the True Cache or from the primary database. The True Cache satisfies that query. And that's where the data will be fetched from. If not, then from the primary database. On start up, True Cache is empty. So it starts reading large chunks of data to populate the True Cache. So after a block is cached, then again, it can be automatically updated, apply the redo to it-- very similar to the Oracle Active Data Guard. In the data returned, it is always going to be consistent. 04:04 Lois: Is it going to be current data? Bill: Maybe, maybe not. If it's been updated in the primary, if they redo apply hasn't occurred yet, then it's not the most consistent. But as far as the query cache is concerned, it is the most current because we only display consistent. You can have multiple True Caches. You can save the same database application service to the True Cache as you can partition it. 04:28 Nikita: I'm curious about the memory requirements, Bill. How crucial is memory for True Cache's performance? Bill: You need to have significant amount of memory. Memory, memory, memory. So True Cache is completely memory, memory. So I want to have all my data possible in there. The more memory you have, the less likely something is going to age out. And of course, just like with the standard caching, you can also pin objects to stay in the True Cache. Yeah, like I said, there are some requirements for storage, even though it's called diskless because of, again, redo log files, configuration files like the control files, SP file. And again it is read only. 05:11 Lois: Can you explain the differences between using physical and logical connections with True Cache? How does this impact the way applications interact with the database? Bill: So with using the True Cache, we have two physical connections, and we can have one to the primary database and one to the True Cache. Each connection has a database application service associated with it, and it's going to choose which connection to use based whether it's going to go to the True Cache or to the primary database. The second way is the application maintains one logical connection that uses the application service for the primary database. It's the JDBC thin driver, starting with Oracle Database 23 is available. It's going to maintain the physical connections to the primary database and the True Cache itself. Now, the logical connection, the one logical and one physical, is for Java applications only. Applications that work with JSON, we extend the HTTP entity tag support for that. So a database GET request to the True Cache is going to compute the ETag, insert it into the return document. 06:27 Nikita: But what happens if there's a mismatch when the modified document is put back into the primary database? Bill: Well, then the database is going to verify. OK, what happens with that? It's going to verify the document row still matches that ETag for that. If with that put command, let's say, I have new data here, the row is going to match that ETag that was automatically updated. If there's no match, another user has changed the data and the PUT request is rejected. So the PUT request can be retired using the new data. 07:05 Are you planning to become an Oracle Certified Professional this year?

Head over to mylearn.oracle.com and create an account to jump-start your journey towards certification today! 07:48 Nikita: Welcome back! Now, how do you configure True Cache, Bill? Bill: You can configure True Cache one of two ways. You can either use the Database Configuration Assistant, which actually makes it a little simpler to configure it, and you can also manually create it. You have some environment options. One is a uniform configuration where you can deploy identical True Cache that use the same database application service. Another way is partition configuration. The data is going to be divided across multiple True Caches, which, each cache is a different subset of the data. You can also deploy True Cache in a RAC environment. As one might expect, there are some additional configuration steps for a RAC environment. You want to make sure you verify your configuration, that the database application services are working as expected after you configure it. And then, optionally, you can enable DML redirection. What that will do, it writes data to the primary database, and that data is automatically updated in the cache. It's very similar how to the Oracle Active Data Guard works. Because the DML redirection uses more resources, it's not recommended for update-intensive applications. There is a parameter, a ADG_REDIRECT_DML initialization parameter, that you will set to True in order to do that. 09:18 Lois: Bill, what are the specific challenges or considerations that administrators should be aware of during the configuration process? Bill: You do need to make sure your network is configured for True Cache in the primary database. So optionally, you can create a remote listener for high availability. But you create your True Cache. You go ahead, and make sure that you have your primary database. You want the network configuration for both of those. And then you create the True Cache. Once the True Cache is created, you're going to create the application services associated with the database. And then, you're going to start the database application services on the True Cache. When it comes to naming the application service names, each primary database application is going to be associated with a corresponding True Cache application service. To help simplify things a little bit, in the naming convention, you'll notice in our examples-- for example, if we have SALES as the primary database service, then we have the True Cache, we have SALES_TC, standing for True Cache, so it's easily identified. You don't have to do that, but it's kind of recommended to do that, some way that you're going to identify it. So we're going to start our True Cache services. And you only start the True Cache services on the True Cache instances. Because it's the database services on the database that you need to make sure are started. And they are read-only. 10:46 Lois: Are there some best practices for maximum availability architecture? Bill: Uniform configuration seems to be a popular one. Why? Because I am going to have the both True Caches can be shared. That way, hopefully, I'm getting full usage out of both. And maybe if I have one service going to one, it might be minimally used. Whereas, the other one might be over. Hey, I could use more memory over here. We'll also recommend use the JDBC 23ai UCP, Universal Connection Pool, for the application. So that can lessen the impact. If one True Cache becomes unavailable, as far as, OK, I need to reroute over here-- benefit of uniform configuration also. Prepopulate the cache. You want to go ahead and run the critical workload for that. If you have a planned outage, and you need to shut down the True Cache, you want to make sure you stop the database application service on that True Cache. And then, how are you going to design your True Cache? Are you going to partition it? Are you going to have uniform? Which partition option are you going to use? So you can try to design that to help minimize the number of fetches it has to do from the primary database. And the more you can keep in the True Cache, the better the performance is going to be. 12:09 Nikita: What do I need to keep in mind when it comes to managing True Cache? Bill: One thing you might need to do for managing the True Cache is to monitor the True Cache. There's a couple different ways that we can do it. One, you can use the V$ view, the V$TRUE_CACHE view. And, of course, you can always use the Automatic Workload Repository. 12:30 Lois: Bill, we already spoke about this a bit, but can you tell us more about using True Cache in an application? Bill: There's two ways of using True Cache, as we've seen, physical and logical. Physical, it's going to maintain two connections, front one to the primary database and one to the True Cache. The application can decide which connection to use, based off of what it is trying to do. If it's just reading, long as it's for a service that's configured with True Cache, it can read the True Cache. If it's going to write something, it's going to update, insert, whatever the case might be, it's for the primary database. And you can use any existing client driver as long as you're using the physical connection method. Any programming language will also work. With the one logical connection method, it uses the application service for the primary database. You're going to use the JDBC Thin driver, starting with 23ai. You can use it and it maintains the connection to the primary database and True Cache. This model only works with Java applications, though. It maintains the physical connections. We're going to enable the driver connection. And then, we're going to set the read only. We're going to set it to read only, true. Read only, false, whatever the case might be. And the read only mode is false for a connection by default. False is the default. Java applications only. 14:14 Nikita: What are some best practices for load balancing in a uniform configuration? Bill: You have multiple--multiple True Caches. They're going to service the same database application. They're going to cache the same data. It's the listener that's going to distribute the load balances. So the listener will automatically distribute and load each session to each cache. It will do it randomly and it will do it based off a load. Where can it configure? Where can it send for the best performance. To route the request to the best performing True Cache, you want to make sure that you are using the same listener. So that remote listener parameter should point to the same listener, which is also the primary database listener. Single instance primary database local listener or scan listener, whichever one you're using, points to the primary. For the application for the JDBC URL, should point to the primary database. You'll remember that Thin driver is going to create that logical connection, and it's going to create the physical connection to the primary database into each True Cache. To simplify things and possibly avoid connection issues, you might consider using the LISTENER_NETWORK, so the initialization parameter instead of specifying the remote and local listener separately. Because with the local--with the listener networks, all listeners within the same network name will cross register. 15:44 Lois: Before we wrap up, are there any complementary features that you would recommend using alongside True Cache to further enhance performance or simplify management? Bill: There are features that can complement True Cache-- the server-side result set cache. So you can create--you can go ahead and create the result set that's part of the library cache set aside, a portion of that. You're going to go in, you're going to configure what objects will use that. You can still use that even with True Cache. There's also the KEEP Buffer Pool that can be used. It's a separate pool that you set aside as part of the buffer cache. And you want to make sure you size it so the object that you want to keep in memory in the buffer cache that you size it appropriately. But again, some configuration, you configure the key pool, plus also you go in and alter the objects to use it. And then lastly, there's the database smart flash cache. So again, if your data doesn't fit into memory, you can expand the capacity of by adding flash devices. When you configure the flash cache, if you are using transparent data encryption data, the local flash devices is not supported. So if it's TD encrypted on the primary database, it's going to stay in the buffer cache of the primary database. 17:11 Nikita: Ok! I think we can close the episode with that. Thank you, once again, for joining us, Bill. Lois: Yes thanks! We're learning so much from you.

Enregistré le 14 juin 2024 Téléchargement de l'épisode LesCastCodeurs-Episode-313.mp3 News Langages Android avec Kotlin Multiplatform our Flutter avec Dart ? https://developers.googleblog.com/en/making-development-across-platforms-easier-for-developers/ Des licenciements ont continué chez Google et l'équipe Flutter/Dart comme plein d'autres ont été touchées, mais sur les réseaux sociaux les gens ont pensé que Google désinvestissait dans Flutter et Dart. Par ailleurs, côté Android, ils poussent plutôt du côté de Kotlin et KMP, mais naturellement aussi les gens se sont demandé si Google avait pris parti pour pousser plus Kotlin/KMP plutôt que Flutter/Dart. Pour essayer de mieux faire comprendre aux développeurs l'intérêt des deux plateformes, et leurs avantages et inconvénients, les directeurs des deux plateformes ont rédigé un article commun. Si l'on souhaite une expérience plus proche du hardware et des dernières nouveautés d'Android, et d'avoir aussi une UI/UX vraiment native Android, mieux vaut aller du côté de Kotlin/KMP. Si l'on souhaite par contre une expérience multiplateforme Web, mobile, desktop avec une UX commune cross-plateforme, avec également le partage de business logic à partir d'une même base de code, Flutter et Dart sont plus adaptés.

Selon les chercheurs, cela constitue une avancée significative par rapport aux écouteurs à réduction de bruit existants, qui peuvent annuler efficacement tous les sons, mais ne peuvent pas sélectionner les locuteurs en fonction de leurs caractéristiques vocales. Actuellement, le système ne peut enregistrer qu'un seul locuteur à la fois. Une autre limitation est que l'enregistrement ne réussira que si aucune autre voix forte ne provient de la même direction. L'équipe a mis en open source leur code et leur jeu de données afin de faciliter les travaux de recherche futurs pour améliorer l'audition de la parole cible. Outillage Utiliser LLM pour migrer du framework de testing https://www.infoq.com/news/2024/06/slack-automatic-test-conversion/ Slack a migré 15.000 tests de Enzyme à React Testing Library avec un succès de 80% Migration nécessaire pour le manque de support de Enzyme pour React 18 L'équipe a essayé d'automatiser la conversion avec des transformations AST, mais n'a atteint que 45 % de succès à cause de la complexité des méthodes d'Enzyme et du manque d'accès aux informations contextuelles du DOM. L'équipe a utilisé Claude 2.1 pour la conversion, avec des taux de réussite variant de 40 % à 60 %, les résultats dépendant largement de la complexité des tâches. Suite aux résultats insatisfaisants, l'équipe a décidé d'observer comment les développeurs humains abordaient la conversion des tests unitaires. Les développeurs humains utilisaient leurs connaissances sur React, Enzyme et RTL, ainsi que le contexte du rendu et les conversions AST de l'outil initial pour mieux convertir les tests unitaires. Finalement les ingénieurs de Slack ont combiné transformations AST et LLM en intégrant des composants React rendus et des conversions AST dans les invites, atteignant un taux de réussite de 80 % démontrant ainsi la complémentarité de ces technologies. Claude 2.1 est un modèle de langage de grande taille (LLM) annoncé en novembre 2023 par Anthropic. Il inclut une fenêtre contextuelle de 200 000 tokens, des réductions significatives des taux d'hallucination du modèle, des invites système et permet l'utilisation d'outils. Depuis, Anthropic a introduit la famille de modèles Claude 3, composée de trois modèles distincts, avec des capacités multimodales et une compréhension contextuelle améliorée. Un arbre de syntaxe abstraite (AST) est une représentation arborescente de la structure syntaxique abstraite du code source écrit dans un langage de programmation. Chaque nœud de l'arbre représente une construction du code source. Un arbre de syntaxe se concentre sur la structure et le contenu nécessaires pour comprendre la fonctionnalité du code. Les AST sont couramment utilisés dans les compilateurs et les interpreters pour analyser et examiner le code, permettant diverses transformations, optimisations et traductions lors de la compilation.

Dealing with Legacy Code: When to Let Go and Start Anew

Play Episode Listen Later May 23, 2024 32:37

Welcome back! In our ongoing discussion on improving life and technology, today's focus is on a more dramatic scenario: saving customers from potential disaster due to legacy code. When does legacy code need to be retired, and what signs indicate it's time for a major overhaul? We'll dive into these questions through real-world examples and expert insights. Listen to Rob and Michael Discuss ways to Deal with Legacy Code The Legacy Code Conundrum Legacy code refers to outdated software that still performs necessary functions but is based on old technology. The core question is: when does maintaining legacy code become impractical or even risky? Our host recounted an experience with a client who had a custom application built on the Eclipse foundation RCP with additional dependencies like Adobe Flash. When the host encountered this system in 2021-22, the last update to the code had been in 2014. The application's underlying technology was so outdated that it was incompatible with modern systems. This scenario is not unique; many organizations rely on aging software that becomes increasingly difficult to maintain as technology evolves. The Case Study: A Ten-Year-Old Application In the host's case study, the client's custom application was built on an old version of Java and Eclipse, using technologies like Flash that are no longer supported. The application worked fine until system upgrades rendered it inoperable. Initially running on multiple machines, the application was eventually down to a single operational machine. This machine was critical: if it failed, the entire application would be lost. Despite having the source code, the modernization process was fraught with challenges. The task involved updating libraries, replacing deprecated technologies, and rewriting significant portions of the code. After six months of effort, it became clear that a complete rewrite was necessary. The core JDBC connections were outdated and incompatible with modern systems, necessitating a significant redevelopment effort. When to Rewrite: Key Considerations Technology Obsolescence: If the technology stack is no longer supported, it's a red flag. Modernizing might involve not just updates but a full-scale rewrite. Compatibility Issues: New system upgrades may not support old applications. As seen in the host's example, upgrading to a newer operating system rendered the application unusable. Developer Expertise: Often, the original developers are no longer available, and current teams may lack the knowledge to maintain or update the legacy code effectively. Cost and Risk: Maintaining old code can be costlier and riskier than starting anew. Constant patching can introduce new bugs, and outdated software may pose security risks. The Modernization Approach The podcast highlighted the importance of understanding the existing system and planning a phased approach to modernization: Assessment: Conduct a thorough assessment of the current system, identifying critical components and dependencies. Determine what can be salvaged and what needs replacement. Data Migration: Plan for data migration from the old system to the new. This may involve extracting data manually or through automated scripts. Incremental Development: Instead of a big-bang approach, develop the new system in phases. This allows for continuous integration and testing, reducing the risk of total failure. User Experience: Consider whether the new system needs to replicate the old user experience or if a new, modern interface would be more beneficial. Real-World Challenges Michael, the co-host, shared his current project in the healthcare sector involving an old IBM AS/400 system. This green-screen, keyboard-driven application was solid but outdated. Key challenges included integration with unsupported systems and the need for continuous deployment and integration. Legacy systems often lack clear documentation, making it hard to understand their full functionality. Moreover, integration points with other outdated applications can further complicate the modernization effort. For Michael's client, the healthcare application was crucial for billing and patient information management, making its stability and modernization a high priority. Modernizing Legacy Code Modernizing legacy code is often more practical and safer than maintaining outdated systems. By assessing the current state, planning data migration, and developing incrementally, organizations can ensure a smoother transition. The goal is not just to replace old technology but to build a robust, modern solution that can evolve with future technological advancements.

Fredrik has Matt Topol and Lars Wikman over for a deep and wide chat about Apache Arrow and many, many topics in the orbit of the language-independent columnar memory format for flat and hierarchical data. What does that even mean? What is the point? And why does Arrow only feel more and more interesting and useful the more you think about deeply integrating it into your systems? Feeding data to systems fast enough is a problem which is focused on much less than it ought to be. With Arrow you can send data over the network, process it on the CPU - or GPU for that matter- and send it along to the database. All without parsing, transformation, or copies unless absolutely necessary. Thank you Cloudnet for sponsoring our VPS! Comments, questions or tips?

And yet, we - as a community - seem to want to keep doing that. Case-in-point, this post on tab-size that I am writing right now! To be clear, this is not a Tabs vs. Spaces article. In this case, I am using "tab size" to generally refer to indentation, having nothing to do with your mode of indication. This is a post about quantity of indentation.

I checked the UDF that was performing the query (using QB) and the query was configured to be cached for 5 minutes... but overhead-wise, it was still taking 42ms each time. The "Number of Queries" for the request was 57 and most of the queries were similar cached 40ms lookups and it started adding up to 1,452ms overall. I wondered if there was anything I could do to add self-contained caching to UDFs that could benefit from them. I didn't want to save the response to the session (YIKES! I've seen some code that does this) or use cachePut/cacheGet since the caching only needs to live for a single request of "repetitive access".https://dev.to/jamoca/caching-repetitive-udf-access-to-request-scope-using-argument-stringifiedhashed-key-3lln 12/8/22 - Blog - The 12 Days of Christmas - ITB 2022 Video Release— Day 1It's that time of year again.

Making the Most of Business Data is One of the Biggest Challenges Organizations Face — and APOS Live Data Gateway Can Solve Those Challenges

Futurum Tech Podcast

In this episode of the Futurum Tech Webcast, principal analyst Shelly Kramer is joined by Allan Pym, Chief Operating Officer at APOS, for a conversation on the challenges making the most of business data presents for organizations, and how APOS Live Data Gateway is helping solve those challenges — and in real time. We all know that data is crucial for today's organizations. From sales and marketing to manufacturing and maintenance, smart organizations need data to make decisions in real time. However, with so much data being gathered in so many different places, it can often feel impossible, overwhelming, or both to wrangle it intelligently. So, what can organizations do to make the most of their data? Are there other technology solutions that can help? Why does real-time matter when it comes to accessing and utilizing data? That's exactly what Allan and I covered today, and if you're wrestling with data challenges, it's a conversation you'll very much enjoy. We covered the following: We know that data is important, that's not a secret. In fact, some 94 percent of organizations report needing access to multiple data sources to support their decision-making — but not every organization knows what to do with their data. Allan shared some of the challenges he and the team at APOS are seeing as organizations wrestle with data connectivity. That's not at all difficult to understand, as research shows that on average companies are drawing from more than 400 different data sources. To compound that massive amount of data coming from myriad sources, one-third of companies report experiencing trouble simply connecting those sources together, let alone pulling accurate or meaningful insights from them. We discussed live connectivity: what it is and why it's so important for organizations today. Allan walked us through the APOS Live Data Gateway, its purpose and the key benefits organizations can experience using its three layers of functionality (Data Connection, Data Preparation, and Data Consumption) and three types of data views that can be utilized within the Data Preparation Layer. We explored APOS Live Data Gateway's Data Connection layer, where the solution makes the connection to data, and we talked about some of the data sources that APOS Live Data Gateway provides connectivity with. We explored both the Data Preparation layer and the Data Consumption layer, including how APOS Live Data Gateway works with SAP Solutions and how live connectivity versus import connectivity works with SAP Analytics Cloud. Allan shared that APOS Live Gateway works with analytics solutions beyond just SAP Analytics Cloud, including live connectivity from Power BI to SAP Analytics Cloud, as well as the expanded consumption options that include Odata, ODBC, and JDBC, in the unified semantic layer. Lastly, Allan shared some stories from customers who are currently using APOS Live Data Gateway which, as always, was one of my favorite parts of the conversation. If you're thinking about getting arms around your data and know that live, real-time data is what you need, this is a conversation you should make time for.

What Could Go Wrong with a Kafka JDBC Connector?

Streaming Audio: a Confluent podcast about Apache Kafka

Play Episode Listen Later Aug 4, 2022 41:10 Transcription Available

Java Database Connectivity (JDBC) is the Java API used to connect to a database. As one of the most popular Kafka connectors, it's important to prevent issues with your integrations. In this episode, we'll cover how a JDBC connection works, and common issues with your database connection. Why the Kafka JDBC Connector? When it comes to streaming database events into Apache Kafka®, the JDBC connector usually represents the first choice for its flexibility and the ability to support a wide variety of databases without requiring custom code. As an experienced data analyst, Francesco Tisiot (Senior Developer Advocate, Aiven) delves into his experience of streaming Kafka data pipeline with JDBC source connector and explains what could go wrong. He discusses alternative options available to avoid these problems, including the Debezium source connector for real-time change data capture. The JDBC connector is a Java API for Kafka Connect, which streams data between databases and Kafka. If you want to stream data from a rational database into Kafka, once per day or every two hours, the JDBC connector is a simple, batch processing connector to use. You can tell the JDBC connector which query you'd like to execute against the database, and then the connector will take the data into Kafka. The connector works well with out-of-the-box basic data types, however, when it comes to a database-specific data type, such as geometrical columns and array columns in PostgresSQL, these don't represent well with the JDBC connector. Perhaps, you might not have any results in Kafka because the column is not within the connector's supporting capability. Francesco shares other cases that would cause the JDBC connector to go wrong, such as: Infrequent snapshot timesOut-of-order eventsNon-incremental sequencesHard deletesTo help avoid these problems and set up a reliable source of events for your real-time streaming pipeline, Francesco suggests other approaches, such as the Debezium source connector for real-time change data capture. The Debezium connector has enhanced metadata, timestamps of the operation, access to all logs, and provides sequence numbers for you to speak the language of a DBA. They also talk about the governance tool, which Francesco has been building, and how streaming Game of Thrones sentiment analysis with Kafka started his current role as a developer advocate.

About PhilipPhilip Griffiths is VP Global Business Development and regularly speaks at events from DevOps to IoT to Cyber Security. Prior to this, he worked for Atos IT Services in various roles working with C-suit executives to realise their digital transformation. He lives in Cambridge with his wife and two daughters.Links: NetFoundry: https://netfoundry.io/ Blog article: https://netfoundry.io/demystifying-the-magic-of-zero-trust-with-my-daughter-and-opensource/ netfoundry.io/screaminginthecloud: https://netfoundry.io/screaminginthecloud TranscriptAnnouncer: Hello, and welcome to Screaming in the Cloud with your host, Chief Cloud Economist at The Duckbill Group, Corey Quinn. This weekly show features conversations with people doing interesting work in the world of cloud, thoughtful commentary on the state of the technical world, and ridiculous titles for which Corey refuses to apologize. This is Screaming in the Cloud.Corey: Today's episode is brought to you in part by our friends at MinIO the high-performance Kubernetes native object store that's built for the multi-cloud, creating a consistent data storage layer for your public cloud instances, your private cloud instances, and even your edge instances, depending upon what the heck you're defining those as, which depends probably on where you work. It's getting that unified is one of the greatest challenges facing developers and architects today. It requires S3 compatibility, enterprise-grade security and resiliency, the speed to run any workload, and the footprint to run anywhere, and that's exactly what MinIO offers. With superb read speeds in excess of 360 gigs and 100 megabyte binary that doesn't eat all the data you've gotten on the system, it's exactly what you've been looking for. Check it out today at min.io/download, and see for yourself. That's min.io/download, and be sure to tell them that I sent you.Corey: This episode is sponsored by our friends at Oracle Cloud. Counting the pennies, but still dreaming of deploying apps instead of “Hello, World” demos? Allow me to introduce you to Oracle's Always Free tier. It provides over 20 free services and infrastructure, networking, databases, observability, management, and security. And—let me be clear here—it's actually free. There's no surprise billing until you intentionally and proactively upgrade your account. This means you can provision a virtual machine instance or spin up an autonomous database that manages itself, all while gaining the networking, load balancing, and storage resources that somehow never quite make it into most free tiers needed to support the application that you want to build. With Always Free, you can do things like run small-scale applications or do proof-of-concept testing without spending a dime. You know that I always like to put asterisks next to the word free? This is actually free, no asterisk. Start now. Visit snark.cloud/oci-free that's snark.cloud/oci-free.Corey: Welcome to Screaming in the Cloud. I'm Corey Quinn. Today's promoted episode is about a topic that is near and dear to my heart. In the AWS universe, we have seen over time that the networking has gotten more and more capable going from EC2 Classic to the world of VPC network to a whole bunch of other things. But with that capability comes a stupendous amount of complexity, to the point where the easy answer to, “Do you understand how networking works within AWS?” Is, of course, no, “I don't.”I'm joined today by Philip Griffiths, who's the Head of Business Development at NetFoundry. Philip, thank you for joining me.Philip: Pleasure to be here, Corey.Corey: So, NetFoundry has what I would argue to be one of the most intriguing-slash-differentiated approaches to handling that ever-increasing complexity around the networking story, not just in AWS, but a number of different cloud providers, and between them, and that approach is to ignore it completely. Have I nailed the salient approach here with that, I guess we'll call it a flippant statement.Philip: Yeah, I'd probably say so. It's the interesting thing where a lot of people say cloud networking is hard, and from our perspective, it should just be super easy, you should be able to provision it in a few minutes with only outbound ports, and set up your policy so that malicious actors can't get inside it. It should be that easy, and programmable, and it's a shame that the current world is not.Corey: One of the hard problems has always been in, I guess, security, which is the thing that everyone pretends to care about right up front, but in practice, often winds up bolting it on after the fact because, “We care about security,” is sort of the trademark phrase of things that we see, usually an email announcing a data breach when it was very clear that companies did not care about security. It's not just me complaining about how complex the network stack is, but by what directly flows from that. If you aren't able to fit all of that into your head as far as what's going on from a security perspective, the odds of misconfiguration creep in and you don't really become aware of what your risk exposure is. I'm really partial to the idea of just avoiding it entirely. Is NetFoundry, effectively, a network overlay? Is it something that goes a bit beyond that? Effectively, where do you folks start and where do you stop?Philip: Yes, that is precisely correct. We are a network overlay that's been built on the principles of zero trust. What is very unique is the ability to be able to start it wherever you want. So yes, you can deploy it from the AWS Marketplace in a few minutes into your VPC or into your operating system, but we also have the ability to actually put it directly into the application stack itself, which has some very interesting complications. What I find as the most interesting starting point is the oxymoron of secure networking.There are no secure networks. It's not possible. Networks are designed to share information and taking it to first principles, you can only isolate networks. And this is why we had the thought process for if we're going to put our overlay network into stuff and make it secure, we have to start at the application level because then we can actually just isolate it to an application communicating into an application, which has profound implications.Corey: The network part is relatively straightforward. I imagine it just becomes, more or less, what resembles a fairly flat network where everything internal is allowed to talk to each other, and then, in turn, this winds up effectively elevating what should be allowed to talk to what and on what ports and whatnot into something that's a lot closer to the application logic, and transcends whatever provider it happens to be traversing.Philip: Yeah, correct. Following the principles of zero trust, we utilize strong embedded identity as a function of what the endpoints are, what the source and destination is. And therefore you build up your policies and services to say what should communicate to what on the basis that the default the least privileged: Absolutely nothing. Your underlay then, the only thing you need is commodity internet with outbound ports. The whole concept of north-south, east-west, if you're app-embedded, you don't even need public DNS; you don't even need DNS at all. Naming conventions go out the window; you don't need to conform to the standards. You know, you could say, “I want to hit Jenkins.” You go to Jenkins because that can be done.Corey: I would approach this entire endeavor with a fair bit of suspicion and no small amount of alarm if it were something that you had developed internally, as far as, “Well, we're just going to replace what amounts to your entire network stack and just go ahead and trust us. It's fine.” But you didn't do that. You're riding on top of the OpenZiti open-source project. And that basically assuages a whole raft of concerns I would have if something like this were proprietary, and people who know what they're doing—who, let's be clear, aren't me—were not able to inspect it and say, “Okay, this passes muster”—as they have done—or alternately, “No, this is terrifyingly dangerous for a variety of excellent reasons.”And it really feels like a lot of the zero-trust stories that we see these days that are taking advantage of either a network overlay approach or shifting authentication into a different layer, have all taken a somewhat similar tack. I used to think it was a good idea; now I'm starting to suspect it might very well be the only viable model. Do you find that that's accurate, or was this a subject of some contention when you were starting out?Philip: So, there's two very interesting [sigh] thoughts that came to me as you were saying that. The number one is yes, we drove forward with OpenZiti because we've seen open-source just completely dominate the industry and everything new that's been built. If you want to deploy an application, you're building on Linux. And in fact, you're probably [laugh] also running on Kubernetes if you're building new. And our objective was to be able to turn OpenZiti into you know, the open-source, zero-trust private network and equivalent where it's just standard: You'll bake your application with Ziti, by design.It will become a check function that people say you have to comply to. When I look at other vendors and how they look at zero-trust, I broadly see a few things that dishearten me. And again, it's a big market, a lot of people—everyone says they're zero-trust nowadays—but I broadly categorize it into a few ways. You have people who are effectively acting as a proxy and they're adding authentication as a way to check what people should have access to. And they may give access to the whole network, they may do granular; it varies between them. In fact, I've just written a blog on this where I effectively call that no-magic zero trust. It's a blog conceptualized within Harry Potter and [unintelligible 00:07:36] a conversation with my daughter.Corey: Yeah, any way to tell a story that beats the traditional enterprise voice is very much appreciated over in this corner of the world.Philip: [laugh]. Yeah, exactly. You have a second tier, which is what I like to think as semi-magical. And that's where you start saying, I am going to use a software-defined perimeter. So, that it's first packet authenticate, or outbound-only based upon embedded identity. And in my eyes, this is basically an invisibility cloak.You then have app-embedded or magical zero-trust. And this is where you're putting the invisibility cloak inside your application, but you're also giving it a port key so that when it needs to connect to something else on the other side of the world, it just happens; it's transparent. And broadly speaking, I think it's very good that the whole world, including the US government is taking zero-trust incredibly importantly, but the distribution of how people tackle a problem is wildly different. There are some zero-trust solutions, which going in the right direction, but fundamentally, if you're putting it in front of your—I won't name a vendor, but there was a vendor who in December, they released a report that said in 90 seconds, common vulnerabilities are exploited something like 96% of the time. 24-hours, 100%.A few days later, they had a 9.8 CVE on their zero-trust VPN concentrator with a public IP, to which I thought, “If you're not patching that immediately, you've got problems if someone is coming into your network.”Corey: Absolutely. We just completed our annual security awareness training here, and so much of it just… it really made my skin crawl, there was an entire module on how to effectively detect phishing emails, and I got to tell you, if they ever start running spellcheck on their some of their [spear-phishing 00:09:23] campaigns, then we're all doomed because that was what the entire training was here. My position is, is that okay, if someone in your company clicks a bad link and it destroys the company's infrastructure, maybe it's the person who's clicking the link that is not necessarily the critical failure point here. Great, if someone compromises an employee workstation, there should be a way to contain the blast radius, they should not now be inside the walls and able to traverse into whatever it is that they want. There should be additional barriers, and zero trust—though it has become, as you say, a catch-all term—seems to be a serious way of looking at this type of compromise and this sort of mitigation against that sort of behavior.Philip: Definitely. And I think that leads itself to, if you're using the correct zero-trust solution, you're able to close [unintelligible 00:10:12] ports, great, you've now massively reduced your attack surface. But what if someone does get a phishing injection of ransomware or something to their endpoint or into their servers? The two things that I like to think about is that if you're creating your overlay network so that the only communication from your server is outbound into the public IPs of your private overlay, then effectively even if the ransomware gets in there, it can't then connect to its command and control module to then go through the kill cycle to other activities. The other is that if you then look at it [instead 00:10:46] of on the server-side, but actually on the client-side, if someone infects my Mac laptop with ransomware, we use this internal application called Mattermost.And it's basically Slack, but open-source. If my Mattermost is Ziti-fied, even I've got ransomware on my device, it can't side-channel attack into Mattermost because you would actually have to break into the Mattermost application and somehow get that Mattermost application to make a compromised query or whatever to get past the system. So really, when I look at zero-trust, it's not about saying, “We're secure. Job done. You know, fire the security department because we don't need them anymore.” It's all about saying—Corey: Box check. Hand it off to the auditor.Philip: [laugh]. Exactly. It's more about saying the cost of attack, the cost of compromised is increased, ideally, to the point where the malicious actors don't have a return on investment. Because if they don't have a return on investment, they will find something else that's not your applications and your systems to try and compromise.Corey: I want to make sure that I'm contextualizing this properly because we're talking—I think—about what almost looks like two different worlds here. There's the, this is how things wind up working in the ecosystem as far as your server environment goes in a cloud provider, but then we're also talking about what goes on in your corporate network of people who are using laptops, which is increasingly being done from home these days. Where do you folks start? Where do you stop? Do you transcend into the corporate network as well, or is this primarily viewed as a production utility?Philip: We do. One of our original design principles with OpenZiti was for it to be a platform rather than a point solution. So, we designed it from the ground up to be able to support any IP packets, TCP, UDP, et cetera, whether you're doing, client-server, server-server, machine-server, server-initiated, client-initiated, yadda, yadda, yadda. So effectively, the same technology can be applied to many different use cases, depending on where you want to use it. We've been doing work recently to handle, let's call them the hard use cases.Probably one of the hardest ones out there is VoIP. There is a playbook that is currently taking place where the VoIP-managed service provider gets DDoSed by malicious actors; the playbook is to move it onto a CDN so that you move the attack surface and you get respite for a few hours. And there's not really any way to solve it because blocking DDoS attacks at layer 3, layer 4 is incredibly difficult unless you can make your PBX dark. And I've seen a couple of our OpenZitiE engineers making calls from one device to another without going through the PBX by doing that over OpenZiti, and being able to solve some of the challenges that's normally associated with VoIP. Again, it was really one of our design principles: How can we make the platform is so flexible that we can do X, Y, Zed today; we're able to build it, again to become a standard, because it can handle anything.Corey: One of the big questions that people are going to have going into this is, and this may sound surprising is a little bit less about technical risk of things like encryption and the rest and a lot more around the idea of okay, does this mean that what you are building becomes a central point of business risk? In other words, if the NetFoundry SaaS installation and wherever they happen to be using as their primary winds up going down, does that mean suddenly nothing can talk to one another? Because it turns out that, you know, computers are not particularly useful in 2022 if they aren't able to talk to other computers, by and large. “The network is the computer,” as was famously stated. What is the failure mode in the event that you experience technical interruption?Philip: We have this internal sessions, which we call Ziti Kitchens, where our engineering team that are creating Ziti educate on stuff that they're building. And one of them in the Ziti Kitchen was around HA, HS, et cetera, and all of the functions that we've built in so that you have redundancy and availability within the different components. Because effectively it's an overlay network, so we've designed it to be a mesh overlay network. You can setup with one point of failure, but then simultaneously, you can very easily set up to have no points of failure because it can have that redundancy and the overlay has its own mechanisms to do things like smart routing and calculation of underlying costs.That cost in that instance would be, well, AWS has gone down, so the latency to send a packet or flow over it is incredibly high, therefore I'm going to avoid that route and send the traffic to another location. I always remember this Ziti Kitchen episode because the underlying technology that does it is called Terminators—Ziti has these things called Terminators—some of the slide there was this little heads over the Terminator with the red eyes, you know, the silver exoskeleton, which always made me laugh.Corey: It's helpful to have things that fail out of band as opposed to—think of the traditional history in security before everything was branded with zero-trust as a prerequisite for exhibiting at RSA; before that was firewalls was the story, and the question always was, if a firewall fails, do you want it to fail open or fail closed? And believe it or not, there are legitimate answers in both directions; depends on context and what you're doing. There are some things for example, IAM in a cloud world where you absolutely never want to fail open, full stop. You would rather someone bodily rip the power cable out the back of the data center rather than let that happen. With something like this, where nothing is able to talk to one another if the entire system goes down, yeah, you want to have the control system that you folks run to be out of band, that is almost always the right answer.As I look at the various case studies that you have on your website and the serious companies that are using what you have built, do you find that they are primarily centralizing around individual cloud providers? Are you seeing that they're using this as a expression of multi-cloud because I can definitely see a story where oh, it helps bring two cloud providers from a networking and security perspective onto the same page, but I can also see, even within one cloud provider, the idea that, hey, I don't have to play around with your ridiculous nonsense? What use cases are you seeing emerge among your customers?Philip: Definitely, the multi-cloud challenge is one that we're seeing as a emerging trend. We do a lot of work with Oracle and, you know, their stated position is multi-cloud is a fact. In fact for them, if we make the secure networking easier, we can bring workloads into our cloud quicker [unintelligible 00:17:21] the main driver between our partnership. We recently did a blog talking about Superclouds and the advent of organizations like Snowflake and HashiCorp and Confluence and Databricks basically building value and business applications which abstracts away the underlying complexity. But you get into the problem of the standard shared security model, where the customer has to deal with DNS and VPNs and MPLS and AWS Private Endpoint or Azure Private Link or whatever they call it, and you have to assemble this Frankenstein of stuff just to enable a VM to communicate to another VM.And the posit of our blog—in fact, we use that exact quote—John Gage—“The computer is the network.” If you can put a network inside the application, you've now given your supercloud superpowers because [unintelligible 00:18:13] natively—I mean, this is very marketing term, but, “Develop once; deploy anywhere,” and be multi-cloud-native.Corey: The idea of being able to adapt to emerging usage patterns without full-on redeploy is handy. What I also would like to highlight, too, is that you are, of course, a network overlay and that is something that is fairly well understood and people have seen it, but your preferred adoption model goes up a couple of steps beyond that into altering the way that the application thinks about these things. And you offer an SDK that ranges from single line of code implementation to I think up to 20, so it's not a massive rewrite of the application, but it does require modification of the stack. What does that buy you, for lack of a better term? Because once you have the application becomes aware of what is effectively its own, “Special network,” quote-unquote, its work to wind up modifying existing applications around something like this. What's the payoff?Philip: So, there's three broad ones that immediately come to my mind. Number one is the highest security that effectively—your private network is inside the app, so you have to somehow break into the app and that can be incredibly complicated, particularly run the app in something like a confidential compute enclave; you can now have a distributed confidential system.The second is what you're getting in programmability. You're able to effectively operate in a fully—even, you know, you get to a GitOps environment. We're currently working on documentation which says, “Hey, you can do all this stuff in GitOps and then it'll go into your CI/CD and that'll talk to the APIs.” And it'll effectively do everything in a completely programmable manner so that you can treat your private networks as cattle rather than as pets.The third is transparency. You used the words earlier of bolt-on networking because that's how we always think about networking security: We bolt it on. As a user, we have to jump through the VPN hoop, we have to go through the bastion, we have to interact with the network. If your private network's inside the application, then you interact with the application. I can have a mobile application on my device and I have no idea that it's part of a private network and that the API is private and the malicious actors can't get to it. I just interact with the application. That is it.That is what no one else has the ability to do and where OpenZiti has its most power because then you get rid of the constant tug of war between the security team that want to lock everything down and the users and the developers who want to move fast and give a great experience. You can effectively have your cake and eat it.Corey: The challenge, of course, with rolling a lot of these things out in a way that becomes highly programmable is that unlocks a bunch of capability, but the double-edged sword there is always one of complexity. I mean, we take a look at the way that AWS networking has progressed, and they finally rolled out the VPC Reachability Analyzer, so when two things can't talk to each other, well, you run this thing and it tells you exactly why, which is super handy. And then just as a way of twisting the knife a little bit, every time you run it, they charge at ten cents for the privilege, which doesn't actually matter in the context of what anyone is being compensated for, until and unless you build this into something programmatic, but it stings a little bit. And the idea of being able to program these things to abstract away a lot of that complexity is incredibly compelling, except for the part where now it feels like it really increases developer burden on a lot of these things. Have you found that to be true? Do you find that it is sort of like a sliding scale? What has the customer experience been around this?Philip: I would say a sliding scale. You know, we had one organization who they started with the OpenZiti Tunnelers, and then we convinced them to use the SDK and [unintelligible 00:21:51], “Oh, this was super easy.” And now they just run OpenZiti on themselves. But then they've also said at some point, we'll use the NetFoundry platform, which effectively gives us a SaaS experience in consuming that. One of the huge focus—well, we've got a few big focuses for product development, but one of the really big areas is really giving more visibility and monitoring so that rather than people having to react to configuration problems or things which they need to fix in order to ensure your perfect network overlay, instead, those things are being seen and automatically dealt with human-in-the-loop if you want it, in order to remove that burden.Because ultimately, if you can get the network to a point where as long as you've got underlay and you've set your policy, the overlay is going to work, it's going to be secure, and it's going to give you the uptime you need, that is the Nirvana that we all have to strive for.Corey: This episode is sponsored in part by our friends at Vultr. Spelled V-U-L-T-R because they're all about helping save money, including on things like, you know, vowels. So, what they do is they are a cloud provider that provides surprisingly high performance cloud compute at a price that—while sure they claim its better than AWS pricing—and when they say that they mean it is less money. Sure, I don't dispute that but what I find interesting is that it's predictable. They tell you in advance on a monthly basis what it's going to going to cost. They have a bunch of advanced networking features. They have nineteen global locations and scale things elastically. Not to be confused with openly, because apparently elastic and open can mean the same thing sometimes. They have had over a million users. Deployments take less that sixty seconds across twelve pre-selected operating systems. Or, if you're one of those nutters like me, you can bring your own ISO and install basically any operating system you want. Starting with pricing as low as $2.50 a month for Vultr cloud compute they have plans for developers and businesses of all sizes, except maybe Amazon, who stubbornly insists on having something to scale all on their own. Try Vultr today for free by visiting: vultr.com/screaming, and you'll receive a $100 in credit. Thats V-U-L-T-R.com slash screaming.Corey: A common criticism of things that shall we say abstract away the network is a fairly common predictable failure mode. I've been making fun of Kubernetes on this particular point for years, and I'm annoyed that at the time that we're recording this, that is still accurate. But from the cloud providers' perspective, when you run Kubernetes, it looks like one big really strangely behaved single-tenant application. And Kubernetes itself is generally not aware of zone affinity, so it could just as easily wind up tossing traffic to the node next to it at zero cost or across an availability zone at two cents per gigabyte, or, God forbid across the internet at nine cents a gigabyte and counting depending upon how it works. And the application-side has absolutely no conception of this.How does OpenZiti address this in the real world because it's one of those things where it almost doesn't matter what you folks charge on top of it, but instead oh wow, this winds up being so hellaciously expensive that we can't use it regardless of whatever benefit it provides just because it becomes a non-starter.Philip: So, when we built the overlay and the mesh, we did it from the perspective of making it as programmable and self-driven as possible. So, with the whole Terminator strategies that was mentioned earlier, it gives you the ability to start putting logic into how you want packets to flow. Today, it does it on a calculation of end-to-end latency and chooses and reroutes traffic in order to give that information. But there's no reason that you couldn't hook it up into understanding what is the numerical in monetary cost for sending a packet along a certain path. Or even what is my application performance monitoring tool saying? Because what that says versus what the network believes could be different things. And effectively you can ingest that information to make your smart routing decisions so all of that logic can exist within the overlay that operates for you.Corey: I will say that really harkens back, on some level, to what I was experimenting with back when I got my CCNA many years ago where there's an idea of routing protocols have built into the idea of the cost of a link. I will freely admit slash confess that at the time of the low-cost link, I assumed this was about what was congested or what would wind up having, theoretically, some transit versus peering agreement. It never occurred to me that I'd have to think about those things in a local network and have to calculate in the Byzantine pricing models of cloud providers. But I've seen examples of folks who are using OpenZiti, and NetFoundry alike, to wind up building in these costing models so that yeah, ideally, it just keeps everything local, but of that path degrades then yes, we would prefer to go over an expensive link than to basically have TCP terminate on the floor until everything comes back up. It sort of feels like there's an awful lot of logic you can bake into that goes well beyond what routing protocols are capable of, just by virtue of exposing that programmability.Well, for this customer because they're on the pre—on the extreme tier, then we want to have the expensive fallback; for low-tier customers, we might want to have them just have an outage until things end. And it really comes down to letting business decisions express themselves in terms of application behavior while in degraded state. I love that idea.Philip: Yeah, I understand. We don't do it today, but there will be a point in the future—I strongly believe—that we'll be able to say, hey, I'll give you an SLA on the internet. Because we'll have such path diversity and visibility of how the internet operates that we'll be able to say within certain risk parameters of what we can deliver. But then you can take it to other logical extremes. You could say, “Hey, I want to build a green overlay. I want to make sure that I'm using Arm instances and in data centers of renewable energy so that my network is green.”Or you can say on a GDPR-compliant overlay so that my data stays within a certain country. You start being able to say—you know, really start dreaming up what are the different policies that I can apply to this because you're applying a central policy to then what is in the distributed system.Corey: One last topic I want to cover before we call it an episode is that you are, effectively, a SaaS company that is built on top of an open-source project. And that has been an interesting path for a lot of companies that early on, figured that if they wrote the software, a lot of the contributors who are doing the lion's share of contribution, that they were clearly the best people to run it. And Amazon's approach towards operational excellence—as they called it—wound up causing some challenges when they launched the Amazon Basics version of that service. I feel like there are some natural defenses built into OpenZiti to keep it from suffering that fate, but I'm very curious to get your take on it.Philip: Fundamentally, our take is that—in fact, our mission is to take what was previously impossible and turn it into a standard. And the only way you can really create standards is to have a open-source that is adopted by the wider community and that ecosystems get built around and into. And that means giving an OpenZiti to absolutely everyone so that they can use it, they can innovate on top of it. We all know that very few people actually want to host their own infrastructure, so we assume a large percentage of people will come and go, “Hey, NetFounder, you provide us the hosting, you provide us the SaaS capability so we don't have to do that ourselves.” But fundamentally in the knowledge that there's something bigger because it's not just us maintaining this project; there's a bunch of people who are doing pull requests and find out cool, fun ways to build further value on what we can build ourselves.We believe the recent history is littered with examples of the new world built on open-source. And fundamentally, we think that's really the only way to be able to change an industry so profoundly as we intend to.Corey: I would also argue that, to be very direct—and I can probably get away with saying this in a way that I suspect you might not be able to—but if AWS had it in their character to simplify things and make it a lot easier for people to work with in a networking sense, what's stopping them? They didn't need to wait for an open-source company to wind up coming out of nowhere and demonstrating the value of this. Customers have been asking it for years. I think that at this point, this is something that is unlikely to ever wind up being integrated into a cloud provider's primary offering. Until and unless the entire industry shifts, at which point we're having a radically different conversation very far down the road.Philip: Yeah, potentially because it opens the interesting thing that if you make it so easy for someone to take their data out, do they use your cloud less? There are some cloud providers that will lean into that because they do see more clouds in the future and others that won't. I see it more myself that as those kind of things happen, it'll be done on a product-by-product basis. For example, we're talking to an organization, and [unintelligible 00:29:49] like, “Oh, could you Ziti-fy our JDBC driver so that when users access our database, they don't have to use a VPN?” [unintelligible 00:29:55], “Yeah. We've already done that with JDBC. We called it ZDBC.”So, we'll just, instead of using the general industry one—probably the Oracle one or something because that's kind of standard—we'll take your one that you've created for yourself and be able to solve that problem for you.Corey: I really want to thank you for taking the time to speak with me today. If people want to learn more, where's the best place to find you?Philip: Best place to go to is netfoundry.io/screaminginthecloud. From there, anyone can grab some free Ziggy swag. Ziggy's our little open-source mascot, cute little piece of pasta with many different outfits. Little sass as well. And you can find further information both on OpenZiti and NetFoundry.Corey: And we will put links to both of those in the [show notes 00:30:40]. Thanks so much for taking the time to speak with me today. I really appreciate it.Philip: It's a pleasure. Thanks, Corey.Corey: Philip Griffiths, Head of Business Development at NetFoundry.

From Batch to Real-Time: Tips for Streaming Data Pipelines with Apache Kafka ft. Danica Fine

Streaming Audio: a Confluent podcast about Apache Kafka

Play Episode Listen Later Jan 13, 2022 29:50 Transcription Available

Implementing an event-driven data pipeline can be challenging, but doing so within the context of a legacy architecture is even more complex. Having spent three years building a streaming data infrastructure and being on the first team at a financial organization to implement Apache Kafka® event-driven data pipelines, Danica Fine (Senior Developer Advocate, Confluent) shares about the development process and how ksqlDB and Kafka Connect became instrumental to the implementation.By moving away from batch processing to streaming data pipelines with Kafka, data can be distributed with increased data scalability and resiliency. Kafka decouples the source from the target systems, so you can react to data as it changes while ensuring accurate data in the target system. In order to transition from monolithic micro-batching applications to real-time microservices that can integrate with a legacy system that has been around for decades, Danica and her team started developing Kafka connectors to connect to various sources and target systems. Kafka connectors: Building two major connectors for the data pipeline, including a source connector to connect the legacy data source to stream data into Kafka, and another target connector to pipe data from Kafka back into the legacy architecture. Algorithm: Implementing Kafka Streams applications to migrate data from a monolithic architecture to a stream processing architecture. Data join: Leveraging Kafka Connect and the JDBC source connector to bring in all data streams to complete the pipeline.Streams join: Using ksqlDB to join streams—the legacy data system continues to produce streams while the Kafka data pipeline is another stream of data. As a final tip, Danica suggests breaking algorithms into process steps. She also describes how her experience relates to the data pipelines course on Confluent Developer and encourages anyone who is interested in learning more to check it out.

He is an advisor to multiple companies including Dell Technologies, Accenture, Observable, Fletch, Orbit, OSS Capital, and the Linux Foundation.Sam received his B.S. in Cognitive Science from UC San Diego, the home of transdisciplinary innovation, in 1994 and is still excited about artificial intelligence, neuroscience, and cognitive psychology.Links: DataStax: https://www.datastax.com Sam Ramji Twitter: https://twitter.com/sramji Open||Source||Data: https://www.datastax.com/resources/podcast/open-source-data Screaming in the Cloud Episode 243 with Craig McLuckie: https://www.lastweekinaws.com/podcast/screaming-in-the-cloud/innovating-in-the-cloud-with-craig-mcluckie/ Screaming in the Cloud Episode 261 with Jason Warner: https://www.lastweekinaws.com/podcast/screaming-in-the-cloud/what-github-can-give-to-microsoft-with-jason-warner/ TranscriptAnnouncer: Hello, and welcome to Screaming in the Cloud with your host, Chief Cloud Economist at The Duckbill Group, Corey Quinn. This weekly show features conversations with people doing interesting work in the world of cloud, thoughtful commentary on the state of the technical world, and ridiculous titles for which Corey refuses to apologize. This is Screaming in the Cloud.Corey: This episode is sponsored in part by our friends at Redis, the company behind the incredibly popular open source database that is not the bind DNS server. If you're tired of managing open source Redis on your own, or you're using one of the vanilla cloud caching services, these folks have you covered with the go to manage Redis service for global caching and primary database capabilities; Redis Enterprise. Set up a meeting with a Redis expert during re:Invent, and you'll not only learn how you can become a Redis hero, but also have a chance to win some fun and exciting prizes. To learn more and deploy not only a cache but a single operational data platform for one Redis experience, visit redis.com/hero. Thats r-e-d-i-s.com/hero. And my thanks to my friends at Redis for sponsoring my ridiculous non-sense. Corey: Are you building cloud applications with a distributed team?

Today's guest has done an awful lot: he led Kubernetes and DevOps Product Management for Google Cloud; he founded the Cloud Foundry Foundation; he set open-source strategy for Microsoft in the naughts; he advises companies including Dell, Accenture, the Linux Foundation; and tying all of that together, it's hard to present a lot of that in a great light because given my own proclivities, that sounds an awful lot like a personal attack. Sam Ramji is the Chief Strategy Officer at DataStax. Sam, thank you for joining me, and it's weird when your resume starts to read like, “Oh, I hate all of these things.”Sam: [laugh]. It's weird, but it's true. And it's the only life I could have lived apparently because here I am. Corey, it's a thrill to meet you. I've been an admirer of your public speaking, and public tweeting, and your writing for a long time.Corey: Well, thank you. The hard part is getting over the voice saying don't do it because it turns out that there's no real other side of public shutting up, which is something that I was never good at anyway, so I figured I'd lean into it. And again, I mean, that the sense of where you have been historically in terms of your career not, “Look what you've done,” which is a subtext that I could be accused of throwing in sometimes.Sam: I used to hear that a lot from my parents, actually.Corey: Oh, yeah. That was my name growing up. But you've done a lot of things, and you've transitioned from notable company making significant impact on the industry, to the next one, to the next one. And you've been in high-flying roles, doing lots of really interesting stuff. What's the common thread between all those things?Sam: I'm an intensely curious person, and the thing that I'm most curious about is distributed cognition. And that might not be obvious from what you see is kind of the… Lego blocks of my career, but I studied cognitive science in college when that was not really something that was super well known. So, I graduated from UC San Diego in '94 doing neuroscience, artificial intelligence, and psychology. And because I just couldn't stop thinking about thinking; I was just fascinated with how it worked.So, then I wanted to build software systems that would help people learn. And then I wanted to build distributed software systems. And then I wanted to learn how to work with people who were thinking about building the distributed software systems. So, you end up kind of going up this curve of, like, complexity about how do we think? How do we think alone? How do we learn to think? How do we think together?And that's the directed path through my software engineering career, into management, into middleware at BEA, into open-source at Microsoft because that's an amazing demonstration of distributed cognition, how, you know, at the time in 2007, I think, Sourceforge had 100,000 open-source projects, which was, like, mind boggling. Some of them even worked together, but all of them represented these groups of people, flung around the world, collaborating on something that was just fundamentally useful, that they were curious about. Kind of did the same thing into APIs because APIs are an even better way to reuse for some cases than having the source code—at Apigee. And kept growing up through that into, how are we building larger-scale thinking systems like Cloud Foundry, which took me into Google and Kubernetes, and then some applications of that in Autodesk and now DataStax. So, I love building companies. I love helping people build companies because I think business is distributed cognition. So, those businesses that build distributed systems, for me, are the most fascinating.Corey: You were basically handed a heck of a challenge as far as, “Well, help set open-source strategy,” back at Microsoft, in the days where that was a punchline. And credit where due, I have to look at Microsoft of today, and it's not a joke, you can have your arguments about them, but again in those days, a lot of us built our entire personality on hating Microsoft. Some folks never quite evolved beyond that, but it's a new ballgame and it's very clear that the Microsoft of yesteryear and the Microsoft of today are not completely congruent. What was it like at that point understanding that as you're working with open-source communities, you're doing that from a place of employment with a company that was widely reviled in the space.Sam: It was not lost on me. The irony, of course, was that—Corey: Well, thank God because otherwise the question where you would have been, “What do you mean they didn't like us?”Sam: [laugh].Corey: Which, on some levels, like, yeah, that's about the level of awareness I would have expected in that era, but contrary to popular opinion, execs at these companies are not generally oblivious.Sam: Yeah, well, if I'd been clever as a creative humorist, I would have given you that answer instead of my serious answer, but for some reason, my role in life is always to be the straight guy. I used to have Slashdot as my homepage, right? I love when I'd see some conspiracy theory about, you know, Bill Gates dressed up as the Borg, taking over the world. My first startup, actually in '97, was crushed by Microsoft. They copied our product, copied the marketing, and bundled it into Office, so I had lots of reasons to dislike Microsoft.But in 2004, I was recruited into their venture capital team, which I couldn't believe. It was really a place that they were like, “Hey, we could do better at helping startups succeed, so we're going to evangelize their success—if they're building with Microsoft technologies—to VCs, to enterprises, we'll help you get your first big enterprise deal.” I was like, “Man, if I had this a few years ago, I might not be working.” So, let's go try to pay it forward.I ended up in open-source by accident. I started going to these conferences on Software as a Service. This is back in 2005 when people were just starting to light up, like, Silicon Valley Forum with, you know, the CEO of Demandware would talk, right? We'd hear all these different ways of building a new business, and they all kept talking about their tech stack was Linux, Apache, MySQL, and PHP. I went to one eight-hour conference, and Microsoft technologies were mentioned for about 12 seconds in two separate chunks. So, six seconds, he was like, “Oh, and also we really like Microsoft SQL Server for our data layer.”Corey: Oh, Microsoft SQL Server was fantastic. And I know that's a weird thing for people to hear me say, just because I've been renowned recently for using Route 53 as the primary data store for everything that I can. But there was nothing quite like that as far as having multiple write nodes, being able to handle sharding effectively. It was expensive, and you would take a bath on the price come audit time, but people were not rolling it out unaware of those things. This was a trade off that they were making.Oracle has a similar story with databases. It's yeah, people love to talk smack about Oracle and its business practices for a variety of excellent reasons, at least in the database space that hasn't quite made it to cloud yet—knock on wood—but people weren't deploying it because they thought Oracle was warm and cuddly as a vendor; they did it because they can tolerate the rest of it because their stuff works.Sam: That's so well said, and people don't give them the credit that's due. Like, when they built hypergrowth in their business, like… they had a great product; it really worked. They made it expensive, and they made a lot of money on it, and I think that was why you saw MySQL so successful and why, if you were looking for a spec that worked, that you could talk through through an open driver like ODBC or JDBC or whatever, you could swap to Microsoft SQL Server. But I walked out of that and came back to the VC team and said, “Microsoft has a huge problem. This is a massive market wave that's coming. We're not doing anything in it. They use a little bit of SQL Server, but there's nothing else in your tech stack that they want, or like, or can afford because they don't know if their businesses are going to succeed or not. And they're going to go out of business trying to figure out how much licensing costs they would pay to you in order to consider using your software. They can't even start there. They have to start with open-source. So, if you're going to deal with SaaS, you're going to have to have open-source, and get it right.”So, I worked with some folks in the industry, wrote a ten-page paper, sent it up to Bill Gates for Think Week. Didn't hear much back. Bought a new strategy to the head of developer platform evangelism, Sanjay Parthasarathy who suggested that the idea of discounting software to zero for startups, with the hope that they would end up doing really well with it in the future as a Software as a Service company; it was dead on arrival. Dumb idea; bring it back; that actually became BizSpark, the most popular program in Microsoft partner history.And then about three months later, I got a call from this guy, Bill Hilf. And he said, “Hey, this is Bill Hilf. I do open-source at Microsoft. I work with Bill Gates. He sent me your paper. I really like it. Would you consider coming up and having conversation with me because I want you to think about running open-source technology strategy for the company.” And at this time I'm, like, 33 or 34. And I'm like, “Who me? You've got to be joking.” And he goes, “Oh, and also, you'll be responsible for doing quarterly deep technical briefings with Bill… Gates.” I was like, “You must be kidding.” And so of course I had to check it out. One thing led to another and all of a sudden, with not a lot of history in the open-source community but coming in it with a strategist's eye and with a technologist's eye, saying, “This is a problem we got to solve. How do we get after this pragmatically?” And the rest is history, as they say.Corey: I have to say that you are the Chief Strategy Officer at DataStax, and I pull up your website quickly here and a lot of what I tell earlier stage companies is effectively more or less what you have already done. You haven't named yourself after the open-source project that underlies the bones of what you have built so you're not going to wind up in the same glorious challenges that, for example, Elastic or MongoDB have in some ways. You have a pricing page that speaks both to the reality of, “It's two in the morning. I'm trying to get something up and running and I want you the hell out of my way. Just give me something that I can work with a reasonable free tier and don't make me talk to a salesperson.” But also, your enterprise tier is, “Click here to talk to a human being,” which is speaking enterprise slash procurement slash, oh, there will be contract negotiation on these things.It's being able to serve different ends of your market depending upon who it is that encounters you without being off-putting to any of those. And it's deceptively challenging for companies to pull off or get right. So clearly, you've learned lessons by doing this. That was the big problem with Microsoft for the longest time. It's, if I want to use some Microsoft stuff, once you were able to download things from the internet, it changed slightly, but even then it was one of those, “What exactly am I committing to here as far as signing up for this? And am I giving them audit rights into my environment? Is the BSA about to come out of nowhere and hit me with a surprise audit and find out that various folks throughout the company have installed this somewhere and now I owe more than the company's worth?” That was always the haunting fear that companies had back then.These days, I like the approach that companies are taking with the SaaS offering: you pay for usage. On some level, I'd prefer it slightly differently in a pay-per-seat model because at least then you can predict the pricing, but no one is getting surprise submarined with this type of thing on an audit basis, and then they owe damages and payment in arrears and someone has them over a barrel. It's just, “Oh. The bill this month was higher than we expected.” I like that model I think the industry does, too.Sam: I think that's super well said. As I used to joke at BEA Systems, nothing says ‘I love you' to a customer like an audit, right? That's kind of a one-time use strategy. If you're going to go audit licenses to get your revenue in place, you might be inducing some churn there. It's a huge fix for the structural problem in pricing that I think package software had, right?When we looked at Microsoft software versus open-source software, and particularly Windows versus Linux, you would have a structure where sales reps were really compensated to sell as much as possible upfront so they could get the best possible commission on what might be used perpetually. But then if you think about it, like, the boxes in a curve, right, if you do that calculus approximation of a smooth curve, a perpetual software license is a huge box and there's an enormous amount of waste in there. And customers figured out so as soon as you can go to a pay-per-use or pay-as-you-go, you start to smooth that curve, and now what you get is what you deserve, right, as opposed to getting filled with way more cost than you expect. So, I think this model is really super well understood now. Kind of the long run the high point of open-source meets, cloud, meets Software as a Service, you look at what companies like MongoDB, and Confluent, and Elastic, and Databricks are doing. And they've really established a very good path through the jungle of how to succeed as a software company. So, it's still difficult to implement, but there are really world-class guides right now.Corey: Moving beyond where Microsoft was back in the naughts, you were then hired as a VP over at Google. And in that era, the fact that you were hired as a VP at Google is fascinating. They preferred to grow those internally, generally from engineering. So, first question, when you were being hired as a VP in the product org, did they make you solve algorithms on a whiteboard to get there?Sam: [laugh]. They did not. I did have somewhat of an advantage [because they 00:13:36] could see me working pretty closely as the CEO of the Cloud Foundry Foundation. I'd worked closely with Craig McLuckie who notably brought Kubernetes to the world along with Joe Beda, and with Eric Brewer, and a number of others.And he was my champion at Google. He was like, “Look, you know, we need him doing Kubernetes. Let's bring Sam in to do that.” So, that was helpful. I also wrote a [laugh] 2000-word strategy document, just to get some thoughts out of my head. And I said, “Hey, if you like this, great. If you don't throw it away.” So, the interviews were actually very much not solving problems in a whiteboard. There were super collaborative, really excellent conversations. It was slow—Corey: Let's be clear, Craig McLuckie's most notable achievement was being a guest on this podcast back in Episode 243. But I'll say that this is a close second.Sam: [laugh]. You're not wrong. And of course now with Heptio and their acquisition by VMware.Corey: Ehh, they're making money beyond the wildest dreams of avarice, that's all well and good, but an invite to this podcast, that's where it's at.Sam: Well, he should really come on again, he can double down and beat everybody. That can be his landmark achievement, a two-timer on Screaming in [the] Cloud.Corey: You were at Google; you were at Microsoft. These are the big titans of their era, in some respect—not to imply that there has beens; they're bigger than ever—but it's also a more crowded field in some ways. I guess completing the trifecta would be Amazon, but you've had the good judgment never to work there, directly of course. Now they're clearly in your market. You're at DataStax, which is among other things, built on Apache Cassandra, and they launched their own Cassandra service named Keyspaces because no one really knows why or how they name things.And of course, looking under the hood at the pricing model, it's pretty clear that it really is just DynamoDB wearing some Groucho Marx classes with a slight upcharge for API level compatibility. Great. So, I don't see it a lot in the real world and that's fine, but I'm curious as to your take on looking at all three of those companies at different eras. There was always the threat in the open-source world that they are going to come in and crush you. You said earlier that Microsoft crushed your first startup.Google is an interesting competitor in some respects; people don't really have that concern about them. And your job as a Chief Strategy Officer at Amazon is taken over by a Post-it Note that simply says ‘yes' on it because there's nothing they're not going to do, or try, and experiment with. So, from your perspective, if you look at the titans, who is it that you see as the largest competitive threat these days, if that's even a thing?Sam: If you think about Sun Tzu and the Art of War, right—a lot of strategy comes from what we've learned from military environments—fighting a symmetric war, right, using the same weapons and the same army against a symmetric opponent, but having 1/100th of the personnel and 1/100th of the money is not a good plan.Corey: “We're going to lose money, going to be outcompeted; we'll make it up in volume. Oh, by the way, we're also slower than they are.”Sam: [laugh]. So, you know, trying to come after AWS, or Microsoft, or Google as an independent software company, pound-for-pound, face-to-face, right, full-frontal assault is psychotic. What you have to do, I think, at this point is to understand that these are each companies that are much like we thought about Linux, and you know, Macintosh, and Windows as operating systems. They're now the operating systems of the planet. So, that creates some economies of scale, some efficiencies for them. And for us. Look at how cheap object storage is now, right? So, there's never been a better time in human history to create a database company because we can take the storage out of the database and hand it over to Amazon, or Google, or Microsoft to handle it with 13 nines of durability on a constantly falling cost basis.So, that's super interesting. So, you have to prosecute the structure of the world as it is, based on where the giants are and where they'll be in the future. Then you have to turn around and say, like, “What can they never sell?”So, Amazon can never sell something that is standalone, right? They're a parts factory and if you buy into the Amazon-first strategy of cloud computing—which we did at Autodesk when I was VP of cloud platform there—everything is a primitive that works inside Amazon, but they're not going to build things that don't work outside of the Amazon primitives. So, your company has to be built on the idea that there's a set of people who value something that is purpose-built for a particular use case that you can start to broaden out, it's really helpful if they would like it to be something that can help them escape a really valuable asset away from the center of gravity that is a cloud. And that's why data is super interesting. Nobody wakes up in the morning and says, “Boy, I had such a great conversation with Oracle over the last 20 years beating me up on licensing. Let me go find a cloud vendor and dump all of my data in that so they can beat me up for the next 20 years.” Nobody says that.Corey: It's the idea of data portability that drives decision-making, which makes people, of course, feel better about not actually moving in anywhere. But the fact that they're not locked in strategically, in a way that requires a full software re-architecture and data model rewrite is compelling. I'm a big believer in convincing people to make decisions that look a lot like that.Sam: Right. And so that's the key, right? So, when I was at Autodesk, we went from our 100 million dollar, you know, committed spend with 19% discount on the big three services to, like—we started realize when we're going to burn through that, we were spending $60 million or so a year on 20% annual growth as the cloud part of the business grew. Thought, “Okay, let's renegotiate. Let's go and do a $250 million deal. I'm sure they'll give us a much better discount than 19%.” Short story is they came back and said, “You know, we're going to take you from an already generous 19% to an outstanding 22%.” We thought, “Wait a minute, we already talked to Intuit. They're getting a 40% discount on a $400 million spend.”So, you know, math is hard, but, like, 40% minus 22% is 18% times $250 million is a lot of money. So, we thought, “What is going on here?” And we realized we just had no credible threat of leaving, and Intuit did because they had built a cross-cloud capable architecture. And we had not. So, now stepping back into the kind of the world that we're living in 2021, if you're an independent software company, especially if you have the unreasonable advantage of being an open-source software company, you have got to be doing your customers good by giving them cross-cloud capability. It could be simply like the Amdahl coffee cup that Amdahl reps used to put as landmines for the IBM reps, later—I can tell you that story if you want—even if it's only a way to save money for your customer by using your software, when it gets up to tens and hundreds of million dollars, that's a really big deal.But they also know that data is super important, so the option value of being able to move if they have to, that they have to be able to pull that stick, instead of saying, “Nice doggy,” we have to be on their side, right? So, there's almost a detente that we have to create now, as cloud vendors, working in a world that's invented and operated by the giants.Corey: This episode is sponsored by our friends at Oracle HeatWave is a new high-performance accelerator for the Oracle MySQL Database Service. Although I insist on calling it “my squirrel.” While MySQL has long been the worlds most popular open source database, shifting from transacting to analytics required way too much overhead and, ya know, work. With HeatWave you can run your OLTP and OLAP, don't ask me to ever say those acronyms again, workloads directly from your MySQL database and eliminate the time consuming data movement and integration work, while also performing 1100X faster than Amazon Aurora, and 2.5X faster than Amazon Redshift, at a third of the cost. My thanks again to Oracle Cloud for sponsoring this ridiculous nonsense.Corey: When we look across the, I guess, the ecosystem as it's currently unfolding, a recurring challenge that I have to the existing incumbent cloud providers is they're great at offering the bricks that you can use to build things, but if I'm starting a company today, I'm not going to look at building it myself out of, “Ooh, I'm going to take a bunch of EC2 instances, or Lambda functions, or popsicles and string and turn it into this thing.” I'm going to want to tie together things that are way higher level. In my own case, now I wind up paying for Retool, which is, effectively, yeah, it runs on some containers somewhere, presumably, I think in Azure, but don't quote me on that. And that's great. Could I build my own thing like that?Absolutely not. I would rather pay someone to tie it together. Same story. Instead of building my own CRM by running some open-source software on an EC2 instance, I wind up paying for Salesforce or Pipedrive or something in that space. And so on, and so forth.And a lot of these companies that I'm doing business with aren't themselves running on top of AWS. But for web hosting, for example; if I look at the reference architecture for a WordPress site, AWS's diagram looks like a punchline. It is incredibly overcomplicated. And I say this as someone who ran large WordPress installations at Media Temple many years ago. Now, I have the good sense to pay WP Engine. And on a monthly basis, I give them money and they make the website work.Sure, under the hood, it's running on top of GCP or AWS somewhere. But I don't have to think about it; I don't have to build this stuff together and think about the backups and the failover strategy and the rest. The website just works. And that is increasingly the direction that business is going; things commoditize over time. And AWS in particular has done a terrible job, in my experience, of differentiating what it is they're doing in the language that their customers speak.They're great at selling things to existing infrastructure engineers, but folks who are building something from scratch aren't usually in that cohort. It's a longer story with time and, “Well, we're great at being able to sell EC2 instances by the gallon.” Great. Are you capable of going to a small doctor's office somewhere in the American Midwest and offering them an end-to-end solution for managing patient data? Of course not. You can offer them a bunch of things they can tie together to something that will suffice if they all happen to be software engineers, but that's not the opportunity.So instead, other companies are building those solutions on top of AWS, capturing the margin. And if there's one thing guaranteed to keep Amazon execs awake at night, it's the idea of someone who isn't them making money somehow somewhere, so I know that's got to rankle them, but they do not speak that language. At all. Longer-term, I only see that as a more and more significant crutch. A long enough timeframe here, we're talking about them becoming the Centurylinks of the world, the tier one backbone provider that everyone uses, but no one really thinks about because they're not a household name.Sam: That is a really thoughtful perspective. I think the diseconomies of scale that you're pointing to start to creep in, right? Because when you have to sell compute units by the gallon, right, you can't care if it's a gallon of milk, [laugh] or a gallon of oil, or you know, a gallon of poison. You just have to keep moving it through. So, the shift that I think they're going to end up having to make pragmatically, and you start to see some signs of it, like, you know, they hired but could not retain Matt [Acey 00:23:48]. He did an amazing job of bringing them to some pragmatic realization that they need to partner with open-source, but more broadly, when I think about Microsoft in the 2000s as they were starting to learn their open-source lessons, we were also being able to pull on Microsoft's deep competency and partners. So, most people didn't do the math on this. I was part of the field governance council so I understood exactly how the Microsoft business worked to the level that I was capable. When they had $65 billion in revenue, they produced $24 billion in profit through an ecosystem that generated $450 billion in revenue. So, for every dollar Microsoft made, it was $8 to partners. It was a fundamentally platform-shaped business, and that was how they're able to get into doctors offices in the Midwest, and kind of fit the curve that you're describing of all of those longtail opportunities that require so much care and that are complex to prosecute. These solved for their diseconomies of scale by having 1.2 million partner companies. So, will Amazon figure that out and will they hire, right, enough people who've done this before from Microsoft to become world-class in partnering, that's kind of an exercise left to the [laugh] reader, right? Where will that go over time? But I don't see another better mathematical model for dealing with the diseconomies of scale you have when you're one of the very largest providers on the planet.Corey: The hardest problem as I look at this is, at some point, you hit a point of scale where smaller things look a lot less interesting. I get that all the time when people say, “Oh, you fix AWS bills, aren't you missing out by not targeting Google bills and Azure bills as well?” And it's, yeah. I'm not VC-backed. It turns out that if I limit the customer base that I can effectively service to only AWS customers, yeah turns out, I'm not going to starve anytime soon. Who knew? I don't need to conquer the world and that feels increasingly antiquated, at least going by the stories everyone loves to tell.Sam: Yeah, it's interesting to see how cloud makes strange bedfellows, right? We started seeing this in, like, 2014, 2015, weird partnerships that you're like, “There's no way this would happen.” But the cloud economics which go back to utilization, rather than what it used to be, which was software lock-in, just changed who people were willing to hang out with. And now you see companies like Databricks going, you know, we do an amazing amount of business, effectively competing with Amazon, selling Spark services on top of predominantly Amazon infrastructure, and everybody seems happy with it. So, there's some hint of a new sensibility of what the future of partnering will be. We used to call it coopetition a long time ago, which is kind of a terrible word, but at least it shows that there's some nuance in you can't compete with everybody because it's just too hard.Corey: I wish there were better ways of articulating these things because it seems from the all the outside world, you have companies like Amazon and Microsoft and Google who go and build out partner networks because they need that external accessibility into various customer profiles that they can't speak to super well themselves, but they're also coming out with things that wind up competing directly or indirectly, with all of those partners at the same time. And I don't get it. I wish that there were smarter ways to do it.Sam: It is hard to even talk about it, right? One of the things that I think we've learned from philosophy is if we don't have a word for it, we can't be intelligent about it. So, there's a missing semantics here for being able to describe the complexity of where are you partnering? Where are you competing? Where are you differentiating? In an ecosystem, which is moving and changing.I tend to look at the tools of game theory for this, which is to look at things as either, you know, nonzero-sum games or zero-sum games. And if it's a nonzero-sum game, which I think are the most interesting ones, can you make it a positive sum game? And who can you play positive-sum games with? An organization as big as Amazon, or as big as Microsoft, or even as big as Google isn't ever completely coherent with itself. So, thinking about this as an independent software company, it doesn't matter if part of one of these hyperscalers has a part of their business that competes with your entire business because your business probably drives utilization of a completely different resource in their company that you can partner within them against them, effectively. Right?For example, Cassandra is an amazingly powerful but demanding workload on Kubernetes. So, there's a lot of Cassandra on EKS. You grow a lot of workload, and EKS business does super well. Does that prevent us from working with Amazon because they have Dynamo or because they have Keyspaces? Absolutely not, right?So, this is when those companies get so big that they are almost their own forest, right, of complexity, you can kind of get in, hang out, do well, and pretty much never see the competitive product, unless you're explicitly looking for it, which I think is a huge danger for us as independent software companies. And I would say this to anybody doing strategy for an organization like this, which is, don't obsess over the tiny part of their business that competes with yours, and do not pay attention to any of the marketing that they put out that looks competitive with what you have. Because if you can't figure out how to make a better product and sell it better to your customers as a single purpose corporation, you have bigger problems.Corey: I want to change gears slightly to something that's probably a fair bit more insulting, but that's okay. We're going to roll with it. That seems to be the theme of this episode. You have been, in effect, a CIO a number of times at different companies. And if we take a look at the typical CIO tenure, industry-wide, it's not long; it approaches the territory from an executive perspective of, “Be sure not to buy green bananas. You might not be here by the time they ripen.” And I'm wondering what it is that drives that and how you make a mark in a relatively short time frame when you're providing inputs and deciding on strategy, and those decisions may not bear fruit for years.Sam: CIO used to—we used say it stood for ‘Career Is Over' because the tenure is so short. I think there's a couple of reasons why it's so short. And I think there's a way I believe you can have impact in a short amount of time. I think the reason that it's been short is because people aren't sure what they want the CIO role to be.Do they want it to be a glorified finance person who's got a lot of data processing experience, but now really has got, you know, maybe even an MBA in finance, but is not focusing on value creation? Do they want it to be somebody who's all-singing, all-dancing Chief Data Officer with a CTO background who did something amazing and solved a really hard problem? The definition of success is difficult. Often CIOs now also have security under them, which is literally a job I would never ever want to have. Do security for a public corporation? Good Lord, that's a way to lose most of your life. You're the only executive other than the CEO that the board wants to hear from. Every sing—Corey: You don't sleep; you wait, in those scenarios. And oh, yeah, people joke about ablative CSOs in those scenarios. Yeah, after SolarWinds, you try and get an ablative intern instead, but those don't work as well. It's a matter of waiting for an inevitability. One of the things I think is misunderstood about management broadly, is that you are delegating work, but not the responsibility. The responsibility rests with you.So, when companies have these statements blaming some third-party contractor, it's no, no, no. I'm dealing with you. You were the one that gave my data to some sketchy randos. It is your responsibility that data has now been compromised. And people don't want to hear that, but it's true.Sam: I think that's absolutely right. So, you have this high risk, medium reward, very fungible job definition, right? If you ask all of the CIO's peers what their job is, they'll probably all tell you something different that represents their wish list. The thing that I learned at Autodesk, I was only there for 15 months, but we established a fundamental transformation of the work of how cloud platform is done at the company that's still in place a couple years later.You have to realize that you're a change agent, right? You're actually being hired to bring in the bulk of all the different biases and experiences you have to solve a problem that is not working, right? So, when I got to Autodesk, they didn't even know what their uptime was. It took three months to teach the team how to measure the uptime. Turned out the uptime was 97.7% for the cloud, for the world's largest engineering software company.That is 200 hours a year of unplanned downtime, right? That is not good. So, a complete overhaul [laugh] was needed. Understanding that as a change agent, your half-life is 12 to 18 months, you have to measure success not on tenure, but on your ability to take good care of the patient, right? It's going to be a lot of pain, you're going to work super hard, you're going to have to build trust with everyone, and then people are still going to hate you at the end. That is something you just have to kind of take on.As a friend of mine, Jason Warner joined Redpoint Ventures recently, he said this when he was the CTO of GitHub: “No one is a villain in their own story.” So, you realize, going into a big organization, people are going to make you a villain, but you still have to do incredibly thoughtful, careful work, that's going to take care of them for a long time to come. And those are the kinds of CIOs that I can relate to very well.Corey: Jason is great. You're name-dropping all the guests we've had. My God, keep going. It's a hard thing to rationalize and wrap heads around. It's one of those areas where you will not be measured during your tenure in the role, in some respects. And, of course, that leads to the cynical perspective as well, where well, someone's not going to be here long and if they say, “Yeah, we're just going to keep being stewards of the change that's already underway,” well, that doesn't look great, so quick, time to do a cloud migration, or a cloud repatriation, or time to roll something else out. A bit of a different story.Sam: One of the biggest challenges is how do you get the hearts and the minds of the people who are in the organization when they are no fools, and their expectation is like, “Hey, this company's been around for decades, and we go through cloud leaders or CIOs, like Wendy's goes through hamburgers.” They could just cloud-wash, right, or change-wash all their language. They could use the new language to describe the old thing because all they have to do is get through the performance review and outwait you. So, there's always going to be a level of defection because it's hard to change; it's hard to think about new things.So, the most important thing is how do you get into people's hearts and minds and enable them to believe that the best thing they could do for their career is to come along with the change? And I think that was what we ended up getting right in the Autodesk cloud transformation. And that requires endless optimism, and there's no room for cynicism because the cynicism is going to creep in around the edges. So, what I found on the job is, you just have to get up every morning and believe everything is possible and transmit that belief to everybody.So, if it seems naive or ingenuous, I think that doesn't matter as long as you can move people's hearts in each conversation towards, like, “Oh, this person cares about me. They care about a good outcome from me. I should listen a little bit more and maybe make a 1% change in what I'm doing.” Because 1% compounded daily for a year, you can actually get something done in the lifetime of a CIO.Corey: And I think that's probably a great place to leave it. If people want to learn more about what you're up to, how you think about these things, how you view the world, where can they find you?Sam: You can find me on Twitter, I'm @sramji, S-R-A-M-J-I, and I have a podcast that I host called Open||Source||Datawhere I invite innovators, data nerds, computational networking nerds to hang out and explain to me, a software programmer, what is the big world of open-source data all about, what's happening with machine learning, and what would it be like if you could put data in a container, just like you could put code in a container, and how might the world change? So, that's Open||Source||Data podcast.Corey: And we'll of course include links to that in the [show notes 00:35:58]. Thanks so much for your time. I appreciate it.Sam: Corey, it's been a privilege. Thank you so much for having me.Corey: Likewise. Sam Ramji, Chief Strategy Officer at DataStax. I'm Cloud Economist Corey Quinn, and this is Screaming in the Cloud. If you've enjoyed this podcast, please leave a five-star review on your podcast platform of choice, whereas if you've hated this podcast, please leave a five-star review on your podcast platform of choice, along with a comment telling me exactly which item in Sam's background that I made fun of is the place that you work at.Corey: If your AWS bill keeps rising and your blood pressure is doing the same, then you need The Duckbill Group. We help companies fix their AWS bill by making it smaller and less horrifying. The Duckbill Group works for you, not AWS. We tailor recommendations to your business and we get to the point.

This one-day training will cover all facets of Adobe ColdFusion that developers need to build applications that can run across multiple cloud providers or on-premise.https://coldfusion-workshop.meetus.adobeevents.com/ Online CF Meetup - "Migrating apps to ColdFusion 2021 from earlier versions", with Charlie ArehartThursday, November 4, 20219:00 AM to 10:00 AM PDTWhile CF2021 has been out now for a year (released in Nov 2020), many orgs may only now be considering moving to it, whether from CF2018 or perhaps CF2016, CF11, CF10, or even earlier. How have the versions changed, in ways that some older code may not run on CF2021? And if you're skipping some CF version/s, what might have tripped you up in those, though not really "new" in CF2021 itself? And what can you do to mitigate such challenges?In this session, CF troubleshooter Charlie Arehart will share from his experience helping folks make such migrations the past year (and for years with previous CF versions), whether in his role as an independent consultant or providing assistance to the CF community. He'll cover things you can consider in advance of the migration as well as things that might help during or after the migration. Most importantly, this talk will focus on the differences between CF2021 and various earlier CF versions. (Note that he has previously given a talk on migrating CF admin settings, and he plans a future talk on some other aspects of migration.)https://www.meetup.com/coldfusionmeetup/events/281800384/ ICYMI - Online CF Meetup - Using LaunchDarkly for feature flag management in CF applications, w/ Brad WoodThursday, October 28, 2021 at 9:00 AM to 10:00 AM PDTFeature flags are a system of enabling certain functionality in your app based on test groups, cross-cutting segments of users, and your internal release processes. Feature flags can be updated on the fly at any time by any user and don't require deploying new code to your servers. LaunchDarkly is a system that helps you manage your feature flags and how they respond to the users of your site. It offers detailed tracking of each user, each flag, and a robust set of rules for determining which users see which features. In this session, we'll see an overview of how to use the new LaunchDarkly SDK which can be used in ColdFusion applications. Demos will include both ColdBox apps and non-ColdBox legacy apps.https://www.meetup.com/coldfusionmeetup/events/281577538/ Recording: https://www.youtube.com/watch?v=cjboLKvbGDc Ortus Webinar for November - Javier Quintero on ForgeBox BusinessDetails coming soonCBWire is ALIVE!!!Grant Copley is knocking out some great new features and documentation on CBWire, follow him or the #cbwire hashtag to keep up on everything.

This will really speed up assessment of the reason of slowness in listed requests. More on that feature (including a screenshot) and still another, below.https://www.carehart.org/blog/client/index.cfm/2021/11/1/fusionreactor_8_7_4_released Blog - Julian Halliwell - Lucee Spreadsheet is now Spreadsheet CFMLThe Lucee Spreadsheet library was born of my frustration 7 years ago at the difficulty of getting spreadsheet functionality to work in Railo and then Lucee.Not long after its release, I started getting requests to support Adobe ColdFusion (ACF). This seemed a bit odd at first. ACF already had built-in spreadsheet functionality so why would you need a third-party tool?The main reason is cross-platform compatibility: allowing for a code base (such as Preside CMS) to run on either CFML engine.https://blog.simplicityweb.co.uk/124/lucee-spreadsheet-is-now-spreadsheet-cfml Blog - Ben Nadel - The Value Class java.time.LocalDateTime Cannot Be Converted To A Date In ColdFusionYesterday, I went to debug an issue with the latest Adobe ColdFusion 2018 Updater. So, I first updated my CommandBox Docker Image (in an effort to reproduce the issue in my local development environment). This sent me down a 4-hour rabbit hole just trying to getting my ColdFusion site up-and-running before I could even debug the originally issue. One of the problems that I ran up against was an incompatibility with Adobe ColdFusion and the latest MySQL Connector/J, version 8.0.23+.https://www.bennadel.com/blog/4144-the-value-class-java-time-localdatetime-cannot-be-converted-to-a-date-in-coldfusion.htmBlog - Ben Nadel - From ColdFusion 10 To ColdFusion 2018 - Preparing For Some Blog LoveThis blog is hella old. It started back in 2006 on Macromedia ColdFusion MX 7. At some point, it was updated to ColdFusion 10, where it remained for the better part of a decade. Recently, I updated it to Adobe ColdFusion 2018. But, the underlying code is still hella old and in much need of some love and tenderness. I'd like to put some time into modernizing the internals. But, before I do that, I need to get a sense of what "modernization" even means when moving from ColdFusion 10 to ColdFusion 2018. This post is really a note to self that refreshes my brain as to what functionality is now available to me in the current Adobe ColdFusion 2018 install.https://www.bennadel.com/blog/4145-from-coldfusion-10-to-coldfusion-2018-preparing-for-some-blog-love.htm Blog - Ben Nadel - Managing Shared Secret Token Rotation Across Systems In Lucee CFML 5.3.7.47When two systems interact, a shared secret is often included with inter-system communication in order to make sure that the given calls are both authorized and have not been tampered with. For various reasons, those shared secrets need to be rotated over time. And, since multiple systems - that need to agree on which secrets are valid - cannot be deployed at the exact same moment, we need to have a token rotation strategy that allows for different systems to rotate tokens at different times. Since I've recently had to deal with this type of token rotation in my ColdFusion applications, I thought it would be good to codify my thoughts in a small demo in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4142-managing-shared-secret-token-rotation-across-systems-in-lucee-cfml-5-3-7-47.htm Blog - Ben Nadel - Securing ColdFusion Scheduled Tasks In A Docker Container Using Lucee CFML 5.3.8.206As I mentioned in my previous post on managing shared secret token rotation across systems, I've been cleaning up some really old code, moving hard-coded passwords into environment variables. One place in which we had a hard-coded password was in our ColdFusion Scheduled Task ingress. As I was updating this code, it occurred to me that the Docker-based reality in which many of us now live has implications on the way in which we can secure our ColdFusion scheduled tasks. As such, I wanted to put together a small demo exploring the various ways in which we can secure a ColdFusion scheduled task running in a Dockerized container using Lucee CFML 5.3.8.206.https://www.bennadel.com/blog/4143-securing-coldfusion-scheduled-tasks-in-a-docker-container-using-lucee-cfml-5-3-8-206.htmTweet - Steven Erat - Mind Blown this Week!Mind blown this week.

As some of you might know I am not always happy with commandbox, especially with the way it handles lucee in production environments.Most of the time, we are working on some long term projects, but recently I had to setup something new, just some proof of concept. So I created a project, ran some of these box coldbox create app wizards and became the proud owner of a brand new cfml advancedscript template setup. https://shiftinsert.nl/a-new-coldbox-app-with-commandbox-a-walk-in-the-park/ Relevant Docs: https://coldbox.ortusbooks.com/for-newbies/60-minute-quick-startBlog - Charle Arehart - CF DevWeek 2021 agenda now postedWhile we've heard for several weeks about the coming Adobe ColdFusion Developer Week event (June 22-24) since it's announcement here and elsewhere, some great news is that the agenda has now been posted. (The topics have also been trickled out via the Adobe CF twitter account.)You can find all the session topics and their times at the registration site. When you click the “Agenda” menu option, you'll find the 3 days of sessions, in two tracks with about 3-4 sessions per track each day, for a total of 20 sessions.https://coldfusion.adobe.com/2021/06/cf-devweek-2021-agenda-now-posted/ Blog - Wil De Bruin - Module dependencies in interceptorsInterceptors in coldbox are very powerful. They are components which listen to events which are announced by the core framework or modules or custom events created by your application. But this post is not about all details of creating interceptors, you can read all about it in the coldbox documentation. I am using them all the time since they are so powerful, but sometimes they don't behave as expected, especially when your interceptor depends on other modules.https://shiftinsert.nl/module-dependencies-in-interceptors/ Blog - Ben Nadel - Managing Lists Of IDs Using HTML FORM Posts In Lucee CFML 5.3.7.47At InVision, I'm in the middle of building a custom feature for one of our clients. This feature lives outside of any SPA (Single-Page Application); and, uses "old school" form submission techniques to process the interactions. The techniques that I'm using are the same ones that I learned 2 decades ago. And they still work perfectly well! This is a testament to both the HTML specification and the way that ColdFusion simplifies the management of form submission data. And while this feels like "old technology" to me, it occurred to me that there might be little gems in here that newer developers don't know about. As such, I wanted to put together a quick demo on managing lists of IDs using HTML FORM posts in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4061-managing-lists-of-ids-using-html-form-posts-in-lucee-cfml-5-3-7-47.htm Blog Adam Cameron - CFML: messing around with mixins (part 1)There was a conversation on the CFML Slack channel the other day about mixing-in functions into objects in CFML. This stemmed from some of the way CFWheels has been architected, such as how the main Controller class is composed:https://blog.adamcameron.me/2021/06/cfml-messing-around-with-mixins-part-1.html Tweet - Brad Wood - New CommandBox Themed shirt on BoxLife storeHey CommandBox users, we've added a cool CommandBox-themed shirt to the BoxLife store that says "Server is Up" to remind you of the magic of starting CF servers!https://www.ortussolutions.com/about-us/shop#!/server+is+up!?idea=60b4a32396e7c070517d5872 #CFML #ColdFusionhttps://twitter.com/bdw429s/status/1400908226854539266 https://twitter.com/bdw429s Blog - Ben Nadel - Changing Function Argument Defaults At Runtime In Lucee CFML 5.3.7.47In the vast, vast majority of cases, when I author a Function in ColdFusion that has default argument values, those values are static. Meaning, the argument falls-back to a hard-coded token like 0 or "" or false. The other day, however, when I was exploring the Password4j password hashing library in Lucee CFML, I created a ColdFusion component that had dynamic Function Argument defaults that could be changed at runtime. To be honest, it felt a little strange at the time. As such, I wanted to isolate the use-case and think-it-through a bit in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4060-changing-function-argument-defaults-at-runtime-in-lucee-cfml-5-3-7-47.htm Blog - FusionReactor - Automatic Root Cause Error AnalysisEvent Snapshots are intended to provide deep-level insight whenever a problem, such as an exception or thread latency occurs. Snapshots are triggered automatically. The Event Snapshot provides automatic root cause error analysis by displaying source code, scope variables, stack trace, and logging information at the point the problem occurs. This, therefore, provides everything you need to isolate the issue as quickly and efficiently as possible.https://www.fusion-reactor.com/blog/technical-blogs/automatic-root-cause-error-analysis/ CFML JobsSeveral positions available on https://www.getcfmljobs.com/Listing over 134 ColdFusion positions from 60 companies across 97 locations in 5 Countries since Dec 1st.2 new jobs listed this weekContract - ColdFusion Developer at Middle Town, NJ - United States Posted Jun 04https://www.getcfmljobs.com/jobs/index.cfm/united-states/CFDev-at-NJ-MiddleTow/11281 Full-Time - Coldfusion Developer at Bengaluru, Karnataka - India Posted Jun 01https://www.getcfmljobs.com/jobs/index.cfm/india/Coldfusion-Developer-at-Bengaluru-Karnataka/11280 Ortus - Senior Developer (USA and El Salvaldor)https://www.ortussolutions.com/about-us/careersForgeBox Module of the WeekJSONPrettyPrint Pretty print JSON objects with line breaks and indentation to make it more human readable.

Normally, when generating a PDF, I would just inline the CFML code inside the CFDocument tag-body; and, I'd use the CFDocumentItem tag with type="pagebreak" to create page-breaks. Which begs the question: if I'm using an externalized HTML source file, how do I create page-breaks? It turns out, since the CFDocument tag supports some CSS, we can use the page-break-before property to generate page-breaks without the CFDocumentItem tag in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4045-creating-page-breaks-in-cfdocument-without-using-cfdocumentitem-in-lucee-cfml-5-3-7-47.htm Blog - Ben Nadel - CFSaveContent Trim And Append Attributes In Lucee CFML 5.3.7.47The other day on the Lucee Dev forum, I proposed that we add a file attribute to the CFSaveContent tag in Lucee CFML. And, as I was writing that proposal, I pulled up the docs page for the CFSaveContent tag; which is when I was surprised to see that Lucee actually offers two additional attributes on that tag: trim and append. I had no idea that these existed. So, I wanted to put together a quick demo (for myself) in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4044-cfsavecontent-trim-and-append-attributes-in-lucee-cfml-5-3-7-47.htm Blog - Adam Cameron - Setting up a MariaDB JDBC datasource in ColdFusion 2021 in Application.cfcThis is how I needed to set my datasource in Application.cfc to get ColdFusion 2021 to connect to MariaDB. I'm writing this because I could not - for the life of me - find this information in any one place in the docs. Nor could I find it anywhere else via Google. I have pieced this together from various sources (including Lucee docs, which were more helpful than the Adobe ColdFusion documentation), and want to put it in one place for my own future reference, or should anyone else need to know how to set up a MariaDB datasouce in ColdFusion using their JDBC driver. The params should also work for any other JDBC datasource.https://blog.adamcameron.me/2021/05/setting-up-mariadb-jdbc-datasource-in.html Blog - Ray Camden - Updating (and Supporting) URL Parameters with Vue.jsToday's article is something that's been kicking around in my head for a few months now, and seeing a recent article (Update URL query parameters as you type in the input using JavaScript) encouraged me to finally get around to writing it. The basic idea is to make it easier for a person to share or bookmark the current state of an application. Let's start with a basic example.https://www.raymondcamden.com/2021/05/08/updating-and-supporting-url-parameters-with-vuejs Blog - Ben Nadel - Collecting HTML Class Name Attributes In Template Rendering In Lucee CFML 5.3.7.47The other day, I was updating a CFML template to include some conditional CSS class names in an ordered list. And, by the time I was done, the CFML looked a hot mess with several ternary operators all being interpolated into one class="" attribute. And, as I sat there, wallowing in the shame of such ugly looking code, it hit me like a bolt of lightening: Angular already solved this problem so elegantly with the NgClass directive that applies dynamic class names based on a set of conditionals. The same exactly thing should be quite doable in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4043-collecting-html-class-name-attributes-in-template-rendering-in-lucee-cfml-5-3-7-47.htm Blog - Ben Nadel - Using Both SrcFile And CFDocumentItem In The Same CFDocument Tag In Lucee CFML 5.3.7.47At InVision, we generate a surprising number of PDF documents. For the most part, the CFDocument tag in Lucee CFML just works. But, sometimes, PDF generation eats-up all the RAM and an OOM (Out of Memory) error is thrown. As such, I'm always on the lookout for ways to tweak the PDF generation process to see if I can consume fewer resources. One idea that I had was to pre-generate the HTML file instead of just rendering the HTML content within the CFDocument tag-body. But, I wasn't sure if I could combine the concept of the srcfile attribute with the child-tag, CFDocumentItem. As such, I wanted to try it out in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4042-using-both-srcfile-and-cfdocumentitem-in-the-same-cfdocument-tag-in-lucee-cfml-5-3-7-47.htm Blog - Ben Nadel - Validating And Documenting Complex Object Structures With CFParam In Lucee CFML 5.3.7.47At InVision, we generate our transactional emails by including a CFML template into a buffer; and then, using that buffer as the body attribute of a CFMail tag. And, since the definition of that template feels somewhat "far away" from the context in which it is being consumed, I've gotten into the habit of parameterizing the template variables using CFParam tags. This way, it's intensely obvious which variables are being used in the template; and, if I accidentally forget to define a variable during refactoring, the template will blow-up when I go to test it. Part of what makes this easy to do is the fact that the CFParam tag can validate complex object structures. I don't often use it this way, so I thought it would be interesting to share in Lucee CFML 5.3.7.47.https://www.bennadel.com/blog/4041-validating-and-documenting-complex-object-structures-with-cfparam-in-lucee-cfml-5-3-7-47.htm Blog - Charlie Arehart - Adobe CF certification now only US$149, including many hours of trainingIf you may not have heard the news or noticed it on the Adobe CF Certification page, the price is now listed as only US$149.https://coldfusion.adobe.com/2021/05/adobe-cf-certification-now-us149-including-many-hours-training/ CFML JobsSeveral positions available on https://www.getcfmljobs.com/Listing over 120 ColdFusion positions from 52 companies across 90 locations in 5 Countries since Dec 1st.Full-Time - Coldfusion/SUNCORP INSURANCE at Sydney NSW - Australia Posted May 11https://www.getcfmljobs.com/jobs/index.cfm/australia/ColdfusionSUNCORP-INSURANCE-at-Sydney-NSW/11267 Full-Time - Coldfusion Developer at Vancouver, BC - Canada Posted May 08https://www.getcfmljobs.com/jobs/index.cfm/canada/Coldfusion-Developer-at-Vancouver-BC/11266 Full-Time - Coldfusion at Bengaluru, Karnataka - India Posted May 07https://www.getcfmljobs.com/jobs/index.cfm/india/Coldfusion-at-Bengaluru-Karnataka/11265 Full-Time - ColdFusion Developer (Secret clearance) at Chantilly, VA - United States Posted May 05https://www.getcfmljobs.com/jobs/index.cfm/united-states/ColdFusion-Developer-Secret-clearance-at-Chantilly-VA/11256 ForgeBox Module of the WeekFacebook Conversions - CFML by Matthew ClementeA CFML wrapper for the Facebook Conversions API.

For this episode we spoke again with Georges Saab, Vice President of Software Development at the Java Platform Group and Manish Gupta, Vice President of Global Marketing for Java and GraalVM. The very first feature that made a massive impact wasn’t a change in the Java language at all. It was the vastly improved library support that happened in the early releases. Between 1.0 and 1.3, these libraries included the Swing window toolkit, the Collections framework, a RPC-like API for remote calls, JDBC for interacting with databases, and more. The standard libraries grew richer, more sophisticated, and allowed Java to become a real enterprise language. In 2004, Java added generics, which allowed types, methods, and interfaces to be specified with the associated data types to be specified when that item was instantiated without sacrificing type safety. “At the time, generics were a challenge and people had strong opinions about them,” said Saab. Today, generics are one of the enduring features of the language. Java may have been designed as a completely object oriented language, but when Java SE 8 was released in 2014, it added Lamda expressions (aka closures), which added some functional programming elements. Not every problem is best served by OOP, and by adding Lambdas, Java became more flexible. Despite its prominence across numerous industries, Java isn’t sitting still. Saab mentioned four big projects coming to Java that had him excited, all designated by codenames: Loom, Valhalla, Leyden, and ZGC.

Mark Mirchandani hosts solo today but is later joined by fellow Googler and Developer Advocate Ray Tsang to talk Java! Ray tells us what’s new with Java 11, including more memory and fewer restrictions for developers. One of the greatest things for Ray is using Java 11 in App Engine because of the management support that it provides. Later, we talk about Spring Boot on GCP. Ray explains the many benefits of using this framework. Developers can get their projects started much more quickly, for example, and with Spring Cloud GCP, it’s easy to integrate GCP services like Spanner and run your project in the cloud. For users looking to containerize their Java projects, JIB can help you do this without having to write a Dockerfile. At the end of the show, Ray and Mark pull it all together by explaining how Spring Boot, Cloud Code, Skaffold, and proper dev-ops can work together for a seamless Java project. Ray Tsang Ray is a Developer Advocate for the Google Cloud Platform and a Java Champion. Ray works with engineering and product teams to improve Java developer productivity on GCP. He also helps Alphabet companies migrate and adopt cloud native architecture. Prior to Google, Ray worked at Red Hat, Accenture, and other consulting companies, where he focused on enterprise architecture, managed solutions delivery, and contributed to open source projects. Aside from technology, Ray enjoys traveling and adventures.

Oh Goody, this is the first episode after coming back from both OracleCodeOne and ApacheCon... and things are happening! First off we start that Oracle JDBC Drivers are FINALLY in Maven Central (hey, missed the mark for a couple of years). We then dive into Jakarta EE 9 updates, including Oracle's position on the "Big Bang" approach to the namespace changes (Hint, you WILL be affected by this, even when you think you aren't). We then look at Java SE 13 (Woohoo!), and that we can finally have Text Blocks (yeah, go crazy with that Json String), and look at Java SE 14 Early builds (including Helpful NullPointerExceptions). Spring is in the news as their Conference SpringOne went underway, and we talk about OracleCodeOne and ApacheCon (good, bad, bust?) Lastly we cover Unionizing Tech Workers and what could it mean to our industry, and we end up by setting the record straight on an article that seems to imply IBM is divesting in Java (This is a far cry from the truth). In all, a fun and great episode to listen while having a beer.

Java: The Programming Language, Not The Island

The History of Computing

Welcome to the History of Computing Podcast, where we explore the history of information technology. Because understanding the past prepares us for the innovations of the future! Today we're going to look at Java. Java is an Indonesian island with over 141 million people. Java man lived there 1.7 million years ago. Wait, wrong java. The infiltration of coffee into the modern world can really trace its roots to ancient coffee forests on the Ethiopian plateau. Sufis in Yemen began importing coffee in the 1400s to make a beverage that would aid in concentration and as a kind of spiritual intoxication. Um, still the wrong java… Although caffeine certainly has a link somewhere, somehow. The history of the Java programming language dates back to early 1991. It all started at Sun Microsystems with the Stealth Project. Patrick Naughton had considered going to NeXT due to limitations in C++ and the C APIs. But he stayed to join Stealth, a secret team of engineers led by a developer Sun picked up from Carnegie Mellon named James Gosling . Stealth was formed to explore new opportunities in the consumer electronics market. This came up when Gosling was writing a program to port software from perf to vax and emulating hardware as many, many, many programers had done before him. I wonder if he realized when he went to build the first Java compiler and the original virtual machine code that would go on to write a dozen books about Java and it would consume most of his professional life. I wonder how much coffee he would have consumed if he had. They soon added Patrick Sheridan to the team. The project was later known as the “Green” project and with the advent of the web, somewhat pivoted into more of a web project. You see, Microsoft and the clones had some runaway success but Apple and other vendors were a factor in the home market. But Sun saw going down market as the future of the company. They added a few more people and rented separate offices in Menlo Park. Lisa Friendly was the first employee in the Java Products Group. Gosling would be lead engineer. John Gage would direct the project. Jonni Kanerva would write Java FAQ1. The team started to build C++ ++ —. Sun founder Bill Joy wanted a language that combined the the best parts of Mesa and C. In 1993, NCSA gave us Mozilla. That Andreessen guy was on the news saying the era of the desktop was over. These brilliant designers knew they needed an embedded application, one that could even be used in a web browser, or an applet. The language was initially called “Oak,” but was later renamed “Java” in 1995, supposedly from a list of random words but really due to massive consumption of coffee imported from the island of Java. By the way, it only aids in concentration up to a point. Then you get jumpy. Like a Halfling. It took the Java team 18 months to develop the first working version. It is unknown how much Java they drank in this time. Between the initial implementation of Oak in the fall of 1992 and the public announcement of Java in the spring of 1995, around 13 people ended up contributing to the design and evolution of the language. They were going to build a language that could sit on top of the operating systems on the market. This would allow them to be platform agnostic. In 1995, the team announced that the evolution of Mosaic, Netscape Navigator, would provide support for Java. Java gave us Write Once, Run Anywhere platform independence. You could run the code on a Mac, on Solaris, or on Windows. Java derives its syntax from C and many of the object oriented features were influenced by C++. Several of Java's defining characteristics come from—or are responses to—its predecessors. Therefore, Java was meant to build on these and become a simple, object-oriented, distributed, interpreted, robust, secure, architectural neutral, portable, high performance, multithreaded, and dynamic language. Before I forget. The "Mocha Java" blend pairs coffee from Yemen and Java to get a thick, syrupy, and highly caffeinated blend that is often found with a hint of cinnamon or clove. Similar to all other computer language, all innovation in the design of the language was driven by the need to solve a fundamental problem that the preceding languages could not solve. To start, the creation of C is considered by many to have marked the beginning of the modern age of computer languages. It successfully synthesized the conflicting attributes that had so troubled earlier languages. The result was a powerful, efficient, structured language that was relatively easy to learn. It also included one other, nearly intangible aspect: it was a programmer's language. Prior to the invention of C, computer languages were generally designed either as academic exercises or by bureaucratic committees. C was designed, implemented, and developed by real, working programmers, reflecting how they wanted to write code. Its features were honed, tested, thought about, and rethought by the people who actually used the language. C quickly attracted many followers who had a near-religious zeal for it. As such, it found wide and rapid acceptance in the programmer community. In short, C is a language designed by and for programmers, as is Java. Throughout the history of programming, the increasing complexity of programs has driven the need for better ways to manage that complexity. C++ is a response to that need in C. To better understand why managing program complexity is fundamental to the creation of C++, consider that in the early days of programming, computer programing was done by manually toggling in the binary machine instructions by use of the front panel or punching cards. As long as programs were just a few hundred instructions long, this worked. Then came Assembly and Fortran and then But as programs grew, assembly language was invented so that a programmer could deal with larger, increasingly complex programs by using symbolic representations of the machine instructions. As programs continued to grow, high-level languages were introduced that gave the programmer more tools with which to handle complexity. This gave birth to the first popular programing language; FORTRAN. Though impressive it had its shortcomings as it didn't encourage clear and easy-to-understand programs. In the 1960s structured programming was born. This is the method of programming championed by languages such as C. The use of structured languages enabled programmers to write, for the first time, moderately complex programs fairly easily. However, even with structured programming methods, once a project reaches a certain size, its complexity exceeds what a programmer can manage. Due to continued growth, projects were exceeding the limits of the structured approach. To overcome this problem, a new way to program had to be invented; it is called object-oriented programming (OOP). Object-oriented programming (OOP) is a programming methodology that helps organize complex programs through the use of inheritance, encapsulation, and polymorphism. In spite of the fact that C is one of the world's great programming languages, there is still a limit to its ability to handle complexity. Once the size of a program exceeds a certain point, it becomes so complex that it is difficult to grasp as a totality. While the precise size at which this occurs differs, depending upon both the nature of the program and the programmer, there is always a threshold at which a program becomes unmanageable. C++ added features that enabled this threshold to be broken, allowing programmers to comprehend and manage larger programs. So if the primary motivation for creating Java was the need for a platform-independent, architecture-neutral language, it was to create software to be embedded in various consumer electronic devices, such as microwave ovens and remote controls. The developers sought to use a different system to develop the language one which did not require a compiler as C and C++ did. A solution which was easier and more cost efficient. But embedded systems took a backseat when the Web took shape at about the same time that Java was being designed. Java was suddenly propelled to the forefront of computer language design. This could be in the form of applets for the web or runtime-only packages known as Java Runtime Environments, or JREs. At the time, developers had fractured into the three competing camps: Intel, Macintosh, and UNIX. Most software engineers stayed in their fortified boundary. But with the advent of the Internet and the Web, the problem that the portability of software between platforms suddenly got important in ways it hadn't been since the forming of ARPANET. Even though many platforms are attached to the Internet, users would like them all to be able to run the same program. What was once an irritating but low-priority problem had become a high-profile necessity. The team realized this pressing need and later made the switch to refocus Java from embedded, consumer electronics to Internet programming. So while the desire for an architecture-neutral programming language provided the initial spark, the Internet ultimately led to Java's large-scale success. So if Java derives much of its character from C and C++, this is by intent. The original designers knew that using familiar syntax would make their new language appealing to legions of experienced C/C++ programmers. Java also shares some of the other attributes that helped make C and C++ successful. Java was designed, tested, and refined by real, working programmers. Not scientists. Java is a programmer's language. Java is also cohesive and logically consistent. If you program well, your programs reflect it. If you program poorly, your programs reflect that, too. Put differently, Java is not a language with training wheels. It is a language for professional programmers. Java 1 would be released in 1996 for Solaris, Windows, Mac, and Linux. It was released as the Java Development Kit, or JDK, and to this day we still refer to the version we're using as JDK 11. Version 2, or 1.2 came in 1998 and with the rising popularity we had a few things that the burgeoning community needed. These included event listeners, Just In Time compilers, and change thread synchronizations. 1.3, code named Kestrel came in 2000, bringing RMI for CORBA compatibility, synthetic proxy classes, the Java Platform Debugger Architecture, Java Naming and Directory Interface in core libraries, the HostSpot JVM, and Java Sound. Merlin, or 1.4 came in 2002 bringing the frustrating regular expressions, native XML processing, logging, Non-Blocking I/O, and SSL. Tiger, or 1.5 came in 2004. This was important. We could autobox, get compile time type safety in generics, static import the static part of a class, annotations for declarative programming, and run time libraries were mapped into memory - a huge improvements to how JVMs work. Java 5 also gave us the version number change. So JDK 1.5 was officially recognized as Java 5. JDK 1.6, or Mustang, came in 2006. This was a big update, bringing monitoring and management tools, compiler access gave us programmatic access to javac and pluggable annotations allowed us to analyze code semantically as a step before javac compiles the code. WebStart got a makeover and SE 6 unified plugins with webstart. Enhanced XML services would be important (at least until he advent of son) and you could mix javascript up with Java. We also got JDBC 4, Character Large Objects, SwingWorker, JTable, better SQL datatypes, native PKI, Kerberos, LDAP, and honestly the most important thing was that it was stable. Although I've never written code stable enough to encounter their stability issues… Not enough coffee I suppose. Sun purchased Oracle in 2009. Wait, no, that's one of my Marvel What If comic book fantasies where the world was a better place. Oracle bought Sun in 2009. After ponying up $5.6 billion dollars, Oracle had a lot of tech based on Sun products and seeing Sun as an increasingly attractive acquisition target by other companies, Oracle couldn't risk someone else swooping in and buying Sun. With all the turmoil created, it took 5 years during a pretty formative time on the web, but we finally got Dolphin, or 1.7, which came in 2011 and gave us compressed, 64-bit pointers, strings in switch statements, the ability to make a binary integer and use underscores in literals, better graphics APIs, more cryptography algorithms, and a new I/O library that gave even better platform compatibilities. Spider, or 1.8, came along in 2014. We got the ability to Launch JavaFX application Jars, statically-linked JNI libraries, a new date an time API, annotation for java types, unsigned integer arithmetic, a JavaScript runtime that allowed us to embed Javascript code in apps - whether this is a good idea or not is still tbd. Lambda functions had been dropped in Java 7 so here we also got lambda expressions. And this kickstarted a pretty interesting time in the development of Java. We got 9 in 2017, 10 and 11 in 2018, 12, 13, and 14 in 2019. Of these, only 8 and 11 are LTS, or commercial Long Term Support releases, basically meaning we got the next major release after 8 in 2018 and according to my trend line should expect the next LTS in 2021 or 2022. JDK 13, when released later in 2019, will give us text blocks, Switch Expressions, improved memory management by returning unused heap memory to the OS, improves application class and data sharing, and brings back the legacy socket API. But it won't likely be an LTS release. Today there are over 45 billion active Java Virtual Machines and java remains arguably the top language for micro service, ci/cd environments, and a number of other use cases. Other languages have come. Other languages have gone. Many are better in their own right. Some are not. Java is not perfect. It was meant to reduce complexity. But as languages evolve they become more complex. A project with a million lines of code is monolithic and probably incorporates plugins or frameworks like spring security as an example, that make code even more complex. But Java is meant to reduce cyclomatic complexity, to allow for a language that is simple enough for a professional to pick up quickly and only be as complex as the quality of the code being compiled. I don't personally love Java. I respect it. And I adore high-quality programmers and their code in any language. But I've had to redo so much work because other languages have come and gone over the years that if I were to be starting a new big monolithic web-app today, I'd probably use Java every time. Which isn't to say that Java isn't useful in micro-service architectures. According to what's required from the contract testing on a service, I might use Java, Go, node, python or even the formerly hipster Ruby. Although I don't love drinking PBR… If I'm writing an Android app, I need to know Java. No matter what the lawyers say. If I'm planning on an enterprise webapp, Java needs to be in the conversation. But usually, I can do the work in a fraction of the time using something like python. But most big companies speak Java. And for good reason. Because of the write once run anywhere approach and the level of permissions a JRE needs, there have been security challenges with running Java on desktop computers. Apple deprecated Java on the Mac in 2010. Users could still instal lications and is the gold standard for those. I'm certainly not advocating going back to the 90s and running Java apps on our desktops any more. No matter what you think of Java, one thing you have to admit, the introduction of the language and the evolution have had a substantial impact on the IT industry and it will continue to do so. A great takeaway here might be that there's always a potential alternative that might be better suited for a given task. But when it comes to choosing a platform that will be there in a decade or 3, getting support, getting a team that can scale, sometimes you might end up using a solution that doesn't immediately seem as well suited to a need. But it can get the job done. As it's been doing since James Gosling and the rest of the team started the project back in the early 90s. So thank you listeners, for sticking with us through this episode of the History of Computing Podcast. We're lucky to have you.
