This discussion explores how leveraging industry-standard CXL memory can be configured as a secondary, composable memory tier to alleviate this constraint. We will highlight some recent work we've done in integrating of this novel class of memory into LLM/RAG/vector database frameworks and workflows. Disaggregated shared memory is envisioned to offer high performance, low latency caches for model/pipeline checkpoints of LLM models, KV caches during distributed inferencing, LORA adaptors, and in-process data for heterogeneous CPU/GPU workflows. We expect to showcase these types of use cases in the coming months. // Bio Bernie is VP of Strategic Partnerships/Business Development for MemVerge.

The top AI news from the past week, every ThursdAI

Hello hello everyone, this is Alex, typing these words from beautiful Seattle (really, it only rained once while I was here!) where I'm attending Microsoft biggest developer conference BUILD. This week we saw OpenAI get in the news from multiple angles, none of them positive and Microsoft clapped back at Google from last week with tons of new AI product announcements (CoPilot vs Gemini) and a few new PCs with NPU (Neural Processing Chips) that run alongside CPU/GPU combo we're familiar with. Those NPUs allow for local AI to run on these devices, making them AI native devices! While I'm here I also had the pleasure to participate in the original AI tinkerers thanks to my friend Joe Heitzberg who operates and runs the aitinkerers.org (of which we are a local branch in Denver) and it was amazing to see tons of folks who listen to ThursdAI + read the newsletter and talk about Weave and evaluations with all of them! (Btw, one the left is Vik from Moondream, which we covered multiple times). I Ok let's get to the news: TL;DR of all topics covered: * Open Source LLMs * HuggingFace commits 10M in ZeroGPU (X)* Microsoft open sources Phi-3 mini, Phi-3 small (7B) Medium (14B) and vision models w/ 128K context (Blog, Demo)* Mistral 7B 0.3 - Base + Instruct (HF)* LMSys created a "hard prompts" category (X)* Cohere for AI releases Aya 23 - 3 models, 101 languages, (X)* Big CO LLMs + APIs* Microsoft Build recap - New AI native PCs, Recall functionality, Copilot everywhere * Will post a dedicated episode to this on Sunday* OpenAI pauses GPT-4o Sky voice because Scarlet Johansson complained* Microsoft AI PCs - Copilot+ PCs (Blog)* Anthropic - Scaling Monosemanticity paper - about mapping the features of an LLM (X, Paper)* Vision & Video* OpenBNB - MiniCPM-Llama3-V 2.5 (X, HuggingFace)* Voice & Audio* OpenAI pauses Sky voice due to ScarJo hiring legal counsel* Tools & Hardware* Humane is looking to sell (blog)Open Source LLMs Microsoft open sources Phi-3 mini, Phi-3 small (7B) Medium (14B) and vision models w/ 128K context (Blog, Demo)Just in time for Build, Microsoft has open sourced the rest of the Phi family of models, specifically the small (7B) and the Medium (14B) models on top of the mini one we just knew as Phi-3. All the models have a small context version (4K and 8K) and a large that goes up to 128K (tho they recommend using the small if you don't need that whole context) and all can run on device super quick. Those models have MIT license, so use them as you will, and are giving an incredible performance comparatively to their size on benchmarks. Phi-3 mini, received an interesting split in the vibes, it was really good for reasoning tasks, but not very creative in it's writing, so some folks dismissed it, but it's hard to dismiss these new releases, especially when the benchmarks are that great! LMsys just updated their arena to include a hard prompts category (X) which select for complex, specific and knowledge based prompts and scores the models on those. Phi-3 mini actually gets a big boost in ELO ranking when filtered on hard prompts and beats GPT-3.5

PowerInfer: Fast Large Language Model Serving with a Consumer-grade GPU

This paper introduces PowerInfer, a high-speed Large Language Model (LLM) inference engine on a personal computer (PC) equipped with a single consumer-grade GPU. The key underlying the design of PowerInfer is exploiting the high locality inherent in LLM inference, characterized by a power-law distribution in neuron activation. This distribution indicates that a small subset of neurons, termed hot neurons, are consistently activated across inputs, while the majority, cold neurons, vary based on specific inputs. PowerInfer exploits such an insight to design a GPU-CPU hybrid inference engine: hot-activated neurons are preloaded onto the GPU for fast access, while cold-activated neurons are computed on the CPU, thus significantly reducing GPU memory demands and CPU-GPU data transfers. PowerInfer further integrates adaptive predictors and neuron-aware sparse operators, optimizing the efficiency of neuron activation and computational sparsity. Evaluation shows that PowerInfer attains an average token generation rate of 13.20 tokens/s, with a peak of 29.08 tokens/s, across various LLMs (including OPT-175B) on a single NVIDIA RTX 4090 GPU, only 18% lower than that achieved by a top-tier server-grade A100 GPU. This significantly outperforms llama.cpp by up to 11.69x while retaining model accuracy. 2023: Yixin Song, Zeyu Mi, Haotong Xie, Haibo Chen https://arxiv.org/pdf/2312.12456v1.pdf

Enregistré le 15 décembre 2023 Téléchargement de l'épisode LesCastCodeurs-Episode-304.mp3 News Aide Les Cast Codeurs et remplis un petit formulaire pour nous guider l'année prochaine https://lescastcodeurs.com/sondage Langages Avec JEP 461, arrivée dans en preview dans Java 22 de la notion de “gatherer” pour les streams https://groovy.apache.org/blog/groovy-gatherers dans cet article de Paul King, de l'équipe Groovy, il montre et contraste ce que l'on pouvait faire en Groovy depuis des années, comme des sliding windows, par exemple explique l'approche des gatherers avec ses opérations intermédiaires gatherer sont des operations intermediaires custom qui prennent un etat et le prochain element pour decided quoi faire, et meme changer le stream d'elements suivants (en publier) (via la fonction integrate certains peuvent permettre de combiner les resultats intermediaires (pour paralleliser) Examples : fenetres de taille fixe, fenettres glissantes Joe Duffy, qui est CEO de Pulumi, mais qui avait travaillé chez Microsoft sur le project Midori (un futur OS repensé) parle du design des exceptions, des erreurs, des codes de retour https://joeduffyblog.com/2016/02/07/the-error-model/ Il compare les codes d'erreurs, les exceptions, checked et non-checked il separe les bugs des erreurs attendues (bugs doivent arreter le process) il raconte l'histoire des unchecked exception et leurs problemes et des checked exceptopns et poourquoi les developeurs java les detestent (selon lui) long article maisn interessant dans ses retours mais lon je ne suis pas allé au bout :smile: Après la disparition de Nashorn dans le JDK, on peut se tourner vers le projet Javet https://www.caoccao.com/Javet/index.html Javet permet d'intégrer JavaScript avec le moteur V8 Mais aussi carrément Node.js c'est super comme capacité car on a les deux mielleurs moteurs, par contre le support hors x86 est plus limité (genre arm sous windows c'est non) Librairies Une partie de l'équipe Spring se fait lourder après le rachat effectif de Broadcom https://x.com/odrotbohm/status/1729231722498425092?s=20 peu d'info en vrai à part ce tweet mais l'acquisition Broadcome n'a pas l'air de se faire dans le monde des bisounours Marc Wrobel annonce la sortie de JBanking 4.2.0 https://www.marcwrobel.fr/sortie-de-jbanking-4-2-0 support de Java 21 possibilité de générer aléatoirement des BIC amélioration de la génération d'IBAN jbanking est une bibliotheque pour manipuler des structures typiques des banques comme les IBAN les BIC, les monnaies, les SEPA etc. Hibernate Search 7 est sorti https://in.relation.to/2023/12/05/hibernate-search-7-0-0-Final/ Support ElasticSearch 8.10-11 et openSearch 2.10-11 Rebasé sur Lucerne 9.8 support sur Amazon OpenSearch Serverless (experimental) attention sous ensemble de fonctionnalités sur Serverless, c'est un API first search cluster vendu a la lambda En lien aussi sur la version 7.1 alpha1 Hibernate ORM 6.4 est sorti https://in.relation.to/2023/11/23/orm-640-final/ support pour SoftDelete (colonne marquant la suppression) support pour les operations vectorielles (support postgreSQL initialement) les fonctions vectorielles sont particulièrement utilisées par l'IA/ML événement spécifiques JFR Intégration de citrus et Quarkus pour les tests d'intégrations de pleins de protocoles et formats de message https://quarkus.io/blog/testing-quarkus-with-citrus/ permet de tester les entrees / sorties attendues de systèmes de messages (HTTP, Kafka, serveur mail etc) top pour tester les application Event Driven pas de rapport mais Quarkus 3.7 ciblera Java 17 (~8% des gens utilisaient Java 11 dans les builds qui ont activé les notifications) Hibernate Search 7.1 (dev 7.1.0.Alpha1) avec dernière version de Lucene (9.8), Infinispan rajoute le support pour la recherche vectorielle. https://hibernate.org/search/releases/7.1/ https://infinispan.org/blog/2023/12/13/infinispan-vector-search Hibernate Search permet maintenant la recherche vectorielle La dernière version est intégrée en Infinispan 15 (dev) qui sortira La recherche vectoriolle et stockage de vecteurs, permettent convertir Infinispan en Embedding Store (langchain) Cloud Comment choisir sa region cloud https://blog.scottlogic.com/2023/11/23/conscientious-cloud-pick-your-cloud-region-deliberately.html pas si simple le coût la securité légale de vos données la consommation carbone de la région choisie (la France est top, la Pologne moins) la latence vs où sont vos clients les services supportés Web Vers une standardisation des Webhooks ? https://www.standardwebhooks.com/ Des gens de Zapier, Twilio, Ngrok, Kong, Supabase et autres, se rejoignent pour essayer de standardiser l'approche des Webhooks La spec est open source (Apache) sur Github https://github.com/standard-webhooks/standard-webhooks/blob/main/spec/standard-webhooks.md Les objectifs sont la sécurité, la reliabilité, l'interopérabilité, la simplicité et la compatibilité (ascendante / descendante) sans la spec, chaque webhook est different dans son comportement et donc les clients doivent s'adapter dans la sematique et les erreurs etc la (meta-) structure de la payload, la taille, la securisation via signature (e.g. hmac), les erreurs (via erreurs HTTP), etc Data et Intelligence Artificielle Google annonce Gemini, son nouveau Large Language Model https://blog.google/technology/ai/google-gemini-ai/#sundar-note modèle multimodal qui peut prendre du texte, en entrée, mais aussi des images, du son, des vidéos d'après les benchmarks, il est largement aussi bon que GPT4 plusieurs tailles de modèles disponible : Nano pour être intégré aux mobiles, Pro qui va être utilisé dans la majeure partie des cas, et Ultra pour les besoins de réflexion les plus avancés Android va rajouter aussi des librairies AICore pour utiliser Gemini Nano dans les téléphones Pixel https://android-developers.googleblog.com/2023/12/a-new-foundation-for-ai-on-android.html Gemini Pro va être disponible dans Bard (en anglais et dans 170 pays, mais l'Europe va devoir attendre un petit peu pour que ce soit dispo) Gemini Ultra devrait aussi rejoindre Bard, dans une version étendue https://blog.google/products/bard/google-bard-try-gemini-ai/ Gemini va être intégré progressivement dans plein de produits Google DeepMind parlant de Gemini https://deepmind.google/technologies/gemini/#introduction Un rapport de 60 pages sur Gemini https://storage.googleapis.com/deepmind-media/gemini/gemini_1_report.pdf Gemini a permis aussi de pouvoir développer une nouvelle version du modèle AlphaCode qui excelle dans les compétitions de coding https://storage.googleapis.com/deepmind-media/AlphaCode2/AlphaCode2_Tech_Report.pdf Liste de petites vidéos sur YouTube avec des interviews et démonstrations des capacités de Gemini https://www.youtube.com/playlist?list=PL590L5WQmH8cSyqzo1PwQVUrZYgLcGZcG malheureusement certaines des annonces sont un peu fausse ce qui a amené un discrédit (non du) sur Gemini par exemple la video “aspirationelle” était vendue comme du réel mais ce n'est pas le cas. et ultra n'est pas disponible encore ausso la comparaison de ChatGPT sur la page (initialement au moins) comparait des choux et des carottes, meme si le papier de recherche était correct Avec la sortie de Gemini, Guillaume a écrit sur comment appeler Gemini en Java https://glaforge.dev/posts/2023/12/13/get-started-with-gemini-in-java/ Gemini est multimodèle, donc on peut passer aussi bien du texte que des images, ou même de la vidéo Il y a un SDK en Java pour interagir avec l'API de Gemini Facebook, Purple Llama https://ai.meta.com/blog/purple-llama-open-trust-safety-generative-ai/ Opensource https://ai.meta.com/llama/ dans l'optique des modeles GenAI ouverts, Facebook fournit des outils pour faire des IA responsables (mais pas coupables :wink: ) notament des benchmarks pour evaluler la sureté et un classifier de sureté, par exemple pour ne pas generer du code malicieux (ou le rendre plus dur) llama purple sera un projet parapluie D'ailleurs Meta IBM, Red Hat et pleins d'autres ont annoncé l'AI Alliance pour une AI ouverte et collaborative entre académique et industriels. Sont notammenrt absent Google, OpenAI (pas ouvert) et Microsoft Juste une annouce pour l'instant mais on va voir ce que ces acteurs de l'AI Alliance feront de concret il y a aussi un guide d'utilisateur l'usage IA responsable (pas lu) Apple aussi se met aux librairies de Machine Learning https://ml-explore.github.io/mlx/build/html/index.html MLX est une librairie Python qui s'inspire fortement de NumPy, PyTorch, Jax et ArrayFire Surtout, c'est développé spécifiquement pour les Macs, pour tirer au maximum parti des processeurs Apple Silicon Dans un des repos Github, on trouve également des exemples qui font tourner nativement sur macOS les modèles de Llama, de Mistral et d'auters https://github.com/ml-explore/mlx-examples non seulement les Apple Silicon amis aussi la memoire unifiee CPU/GPU qui est une des raisons clés de la rapidité des macs Faire tourner Java dans un notebook Jupyter https://www.javaadvent.com/2023/12/jupyter-notebooks-and-java.html Max Andersen explore l'utilisation de Java dans les notebooks Jupyter, au lieu du classique Python il y a des kernels java selon vos besoins mais il faut les installer dans la distro jupyter qu'on utilise et c'est la que jbang installable via pip vient a la rescousse il installe automatiquement ces kernels en quelques lignes Outillage Sfeir liste des jeux orientés développeurs https://www.sfeir.dev/tendances/notre-selection-de-jeux-de-programmation/ parfait pour Noël mais c'est pour ceux qui veulent continuer a challenger leur cerveau après le boulot jeu de logique, jeu de puzzle avec le code comme forme, jeu autour du machine learning, jeu de programmation assembleur Les calendriers de l'Avent sont populaires pour les développeurs ! En particulier avec Advent of Code https://adventofcode.com/ Mais il y a aussi l'Advent of Java https://www.javaadvent.com/ Ou un calendrier pour apprendre les bases de SVG https://svg-tutorial.com/ Le calendrier HTML “hell” https://www.htmhell.dev/adventcalendar/ qui parle d'accessibilité, de web components, de balises meta, de toutes les choses qu'on peut très bien faire en HTML/CSS sans avoir besoin de JavaScript Pour les développeurs TypeScript, il y a aussi un calendrier de l'Avent pour vous ! https://typehero.dev/aot-2023 Un super thread de Clara Dealberto sur le thème de la “dataviz” (data visualization) https://twitter.com/claradealberto/status/1729447130228457514 Beaucoup d'outil librement accessibles sont mentionnés pour faire toutes sortes de visualisations (ex. treemap, dendros, sankey…) mais aussi pour la cartographie Quelques ressources de site qui conseillent sur l'utilisation du bon type de visualisation en fonction du problème et des données que l'on a notemment celui du financial time qui tiens dans une page de PDF Bref c'est cool mais c'est long a lire Une petite liste d'outils sympas - jc pour convertir la sortie de commandes unix en JSON https://github.com/kellyjonbrazil/jc - AltTab pour macOS pour avoir le même comportement de basculement de fenêtre que sous Windows https://alt-tab-macos.netlify.app/ - gron pour rendre le JSON grep-able, en transformant chaque valeur en ligne ressemblant à du JSONPath https://github.com/tomnomnom/gron - Marker, en Python, pour transformer des PDF en beau Markdown https://github.com/VikParuchuri/marker - n8n un outil de workflow open source https://n8n.io/ gron en fait montre des lignes avec des assignments genre jsonpath = value et tu peux ungroner apres pour revenir a du json Marker utilise du machine learning mais il halklucine moins que nougat (nous voilà rassuré) Docker acquiert Testcontainers https://techcrunch.com/2023/12/11/docker-acquires-atomicjar-a-testing-startup-that-raised-25m-in-january/ Annonce par AtomicJar https://www.atomicjar.com/2023/12/atomicjar-is-now-part-of-docker/ Annonce par Docker https://www.docker.com/blog/docker-whale-comes-atomicjar-maker-of-testcontainers/ Architecture Comment implémenter la reconnaissance de chanson, comme Shazam https://www.cameronmacleod.com/blog/how-does-shazam-work il faut d'abord passer en mode fréquence avec des transformées de Fourrier pour obtenir des spectrogrammes puis créer une sorte d'empreinte qui rassemble des pics de fréquences notables à divers endroits de la chanson d'associer ces pics pour retrouver un enchainement de tels pics de fréquence dans le temps l'auteur a partagé son implémentation sur Github https://github.com/notexactlyawe/abracadabra/blob/e0eb59a944d7c9999ff8a4bc53f5cfdeb07b39aa/abracadabra/recognise.py#L80 Il y avait également une très bonne présentation sur ce thème par Moustapha Agack à DevFest Toulouse https://www.youtube.com/watch?v=2i4nstFJRXU les pics associés sont des hash qui peut etre comparés et le plus de hash veut dire que les chansons sont plus similaires Méthodologies Un mémo de chez ThoughtWorks à propos du coding assisté par IA https://martinfowler.com/articles/exploring-gen-ai.html#memo-08 Avec toute une liste de questions à se poser dans l'utilisation d'un outil tel que Copilot Il faut bien réaliser que malheureusement, une IA n'a pas raison à 100% dans ses réponses, et même plutôt que la moitié du temps, donc il faut bien mettre à jour ses attentes par rapport à cela, car ce n'est pas magique La conclusion est intéressante aussi, en suggérant que grosso modo dans 40 à 60% des situations, tu peux arriver à 40 à 80% de la solution. Est-ce que c'est à partir de ce niveau là qu'on peut vraiment gagner du temps et faire confiance à l'IA ? Ne perdez pas trop de temps non plus à essayer de convaincre l'IA de faire ce que vous voulez qu'elle fasse. Si vous n'y arrivez pas, c'est sans doute parce que l'IA n'y arrivera même pas elle même ! Donc au-delà de 10 minutes, allez lire la doc, chercher sur Google, etc. notamment, faire genrer les tests par l'IA dans al foulée augmente les risques surtout si on n'est pas capable de bien relire le code si on introduit un choix de pattern genre flexbox en CSS, si c'est sur une question de sécuriter, vérifier (ceinture et bretelle) est-ce le framework de la semaine dernière? L'info ne sera pas dans le LLM (sans RAG) Quelles capacités sont nécessaires pour déployer un projet AI/ML https://blog.scottlogic.com/2023/11/22/capabilities-to-deploy-ai-in-your-organisation.html C'est le MLOps et il y a quelques modèles end to end Google, IBM mais vu la diversité des organisations, c'est difficile a embrasser ces versions completes ML Ops est une métier, data science est un metier, donc intégrer ces competences sachez gérer votre catalogue de données Construire un process pour tester vos modèles et continuellement La notion de culture de la recherche et sa gestion (comme un portefeuille financier, accepter d'arrêter des experience etc) la culture de la recherche est peu présente en engineering qui est de construire des choses qui foncitonnent c'est un monde pre LLM Vous connaissez les 10 dark patterns de l'UX ? Pour vous inciter à cliquer ici ou là, pour vous faire rester sur le site, et plus encore https://dodonut.com/blog/10-dark-patterns-in-ux-design/ Parmi les dark patterns couverts Confirmshaming Fake Urgency and the Fear of Missing Out Nagging Sneaking Disguised Ads Intentional Misdirection The Roach Motel Pattern Preselection Friend Spam Negative Option Billing or Forced Continuity L'article conclut avec quelques pistes sur comment éviter ces dark patterns en regardant les bons patterns de la concurrence, en testant les interactions UX, et en applicant beaucoup de bon sens ! les dark patterns ne sont pas des accidents, ils s'appuient sur la psychologie et sont mis en place specifiquement Comment choisir de belles couleurs pour la visualisation de données ? https://blog.datawrapper.de/beautifulcolors/ Plutôt que de penser en RGB, il vaut mieux se positionner dans le mode Hue Saturation Brightness Plein d'exemples montrant comment améliorer certains choix de couleurs Mieux vaut éviter des couleurs trop pures ou des couleurs trop brillantes et saturées Avoir un bon contraste Penser aussi aux daltoniens ! j'ai personnellement eu toujours du mal avec saturationm vs brightness faire que les cloueirs en noir et blanc soient separees evant de le remettre (en changeant la brightness de chaque couleur) ca aide les daltoniens eviter les couleurs aux 4 coins amis plutot des couleurs complementaires (proches) rouge orange et jaune (non saturé) et variations de bleu sont pas mal les couleurs saturées sont aggressives et stressent les gens Pourquoi vous devriez devenir Engineering Manager? https://charity.wtf/2023/12/15/why-should-you-or-anyone-become-an-engineering-manager/ L'article parle de l'évolution de la perception de l'engineering management qui n'est plus désormais le choix de carrière par défaut pour les ingénieurs ambitieux. Il met en évidence les défis auxquels les engineering managers sont confrontés, y compris les attentes croissantes en matière d'empathie, de soutien et de compétences techniques, ainsi que l'impact de la pandémie de COVID-19 sur l'attrait des postes de management. L'importance des bons engineering mnanagers est soulignée, car ils sont considérés comme des multiplicateurs de force pour les équipes, contribuant de manière significative à la productivité, à la qualité et au succès global dans les environnements organisationnels complexes. L'article fournit des raisons pour lesquelles quelqu'un pourrait envisager de devenir Engineering Manager, y compris acquérir une meilleure compréhension de la façon dont les entreprises fonctionnent, contribuer au mentorat et influencer les changements positifs dans la dynamique des équipes et les pratiques de l'industrie. Une perspective est présentée, suggérant que devenir Engineering manager peut conduire à la croissance personnelle et à l'amélioration des compétences de vie, telles que l'autorégulation, la conscience de soi, la compréhension des autres, l'établissement de limites, la sensibilité à la dynamique du pouvoir et la maîtrise des conversations difficiles. L'article encourage à considérer la gestion comme une occasion de développer et de porter ces compétences pour la vie.

Data are not all created equal. There are structured (machine-generated) and unstructured (human-generated) data, and each requires a different approach. As a result of the increased use of digital applications and services, unstructured information is growing rapidly. It is estimated that 80-90% of company data is unstructured, and the amount of unstructured data continues to grow at an alarming rate per year. In this episode of The Analytic Mind Podcast, Sam McKay speaks with Kirk Marple, the founder, and CEO of Unstruk Data. Hear about the hidden value in unstructured data and how it impacts the future of data and analytics. Kirk Marple is a Customer-focused Technology leader with extensive expertise with cloud-based microservices, scalable multimedia data ingestion, knowledge graphs (entity extraction/enrichment), machine learning and computer vision integration, and CPU/GPU-based file and data processing workflows. He is highly skilled at architecting and managing teams developing APIs and scalable services, leveraging on-premise and cloud infrastructure, generating significant cost savings, and supporting revenue growth for startups through Fortune 25 companies. Unstruk Data, is a company that is building the industry's leading Unstructured Data Warehouse for automating data preparation via metadata enrichment, integrated compute, and graph-based search. Unstructured data can include anything from audio to visual data, and Kirk explains that analytics can be done on geospatial and temporal unstructured data. Then by using machine learning and artificial intelligence, it is possible to generate knowledge graphs based on this data.

By Michael G. Hull Modern technology has evolved at an even faster pace in the last decade generating cutting-edge innovations and breakthroughs – from artificial intelligence, augmented and virtual reality, decentralized finance, to blockchain and crypto technologies. Today, the world is highly connected more than ever. With the emergence of the next-generation cellular network, 5G is the latest iteration of the global wireless technology standard. Numerous countries are securing the availability of 5G coverage in their areas while there are places with limited availability. In 2021, South Korea, Saudi Arabia, Kuwait, Hong Kong, and the USA lead the countries with 5G network availability and user connection. Addressing Speed and Latency with Edge Computing and 5G Connection Along with the advancement of mobile network technology, the 5G network offers faster data speeds, bigger capacity, reduced latency, and improved mobile network services than its 4G predecessor. The 5G network enables significantly improved features of the previous networks to deliver a better user experience and connectivity. In comparing 4G and 5G speeds, the average 4G speed rate can reach from 10-50 Mbps (megabits per second) with a maximum speed ranging from 150 Mbps-1Gbps (gigabits per second) while the average 5G speed rate starts from 50 Mbps with a max speed rate of 1-10 Gbps. Speed rates may also depend on factors like wireless network connection, geographical location, and device unit. The latest 5G network has another major improvement: low latency. Latency is the measured gap or delay between the data transmission and response. Under the 5G network, reduced latency means faster response to transmitted data in real time, improving the overall mobile network user experience, and opening up opportunities across various industries. Nope — this is not an April fool's joke ? $SNE is coming to #LATOKEN this Monday, April 4th. Stay tuned for the official details ? StrongNode.io (@StrongNodeEdge) April 1, 2022 StrongNode powers mobile edge computing The mobile network industry is fast becoming decentralized with the rise of the 5G network. Shifting to a distributed and decentralized model places the transmission and processing of data towards the edge or closer to the data source with the help of edge computing technology. 5G and edge computing goes hand-in-hand as 5G is necessary to improve mobile broadband network performance and minimize latency for faster processing of high-volume data and increased, even instant, response time. 5G mobile edge computing can provide improved services and performances in gaming on 5G-enabled devices, telecommunications, IoT sensors from manufacturing plants, food delivery, video streaming, media, and entertainment among others. This is where StrongNode.io, an Infrastructure-as-a-Service tech company comes in. Leveraging edge computing technology, StrongNode aims to address high latency with the optimization of devices such as laptops, mobile phones, tablets, and eventually smart TV. The StrongNode Edge technology will harness the underutilized computing resources. CPU/GPU cycles, network bandwidth, and data storage – of digital devices commonly found in households, schools, and enterprises to build an edge network that can power the computing needs of other individuals, institutions, and organizations. With the proliferation of 5G-enabled devices, there will be an increase in the efficiency of use in computing resources leaving a higher percentage that can be shared with other users in the network. StrongNode CEO and Co-founder Daniel Saito said that with the rollout of 5G/6G technology, StrongNode could develop products and services that will help democratize computing for the masses regardless of the digital divide between different societies. With 5G/6G standards designed to have 10x or more faster network speed than the current 4G network, then 5G/6G can potentially enhance not only mobile broadband services ...

Discussion: I'd love some community testing and feedback I've found that flying to settlements is the place where performance is the worst of anywhere in the game. But if I murder all the NPCs and then take off performance is dramatically better. When I first booted up after the update I got the bug where all the NPC vendors were missing from a concourse; and performance was way better than normal. This follows with previous observations that NPC AI can stack up within an instance causing big performance hits on EDH/EDO in space and at settlements/concourses. In these cases I (and others) observe that the CPU/GPU is not even close to being fully utilized. My working theory is that the game engine is slowing down how quickly it sends frames to the processors to draw, not the processors hitting their power limit. This might only be apparent on very fast hardware. Please capture screen shots of your performance meter before and after murdering everyone at a settlement and share them in our hardware channel!

据报道,锤子科技创始人罗永浩昨天发布微博称,将再一次高科技创业。他在与网友互动时透露,重返科技行业后将会涉足VR、AR、MR类领域。据中新经纬,腾讯游戏《QQ堂》发布停运公告,因《QQ堂》项目组战略计划,现正式宣布《QQ堂》将在2022年4月20日停止中国大陆地区的运营。《QQ堂》将在2022年4月20日11点关闭游戏服务器,届时玩家将不能正常登陆游戏。 该游戏已上线17年。36氪获悉,从小红书方面获悉,平台已启动新一轮“虚假营销”治理专项,首批29个涉嫌虚假营销的品牌被封禁。相比此前的治理专项,此次治理范畴将进一步扩大,覆盖整个“代写代发”灰产链的上下游。在小红书上搜索某品牌关键词,相关笔记内容已经无法显示,页面仅出现“该品牌涉嫌虚假营销,相关内容不予展示”的提示。据央视新闻报道,教育部等九部门昨天发布“十四五”学前教育发展提升行动计划,到2025年,全国学前三年毛入园率将达到90%以上,普惠性幼儿园覆盖率达到85%以上,公办园在园幼儿占比将达到50%以上,覆盖城乡、布局合理、公益普惠的学前教育公共服务体系将进一步健全。据TechWeb报道,本周开始接任英特尔CEO之后首次亚洲之行的帕特·基辛格,已同台积电高层会面,就3nm工艺的代工事宜进行了探讨。英特尔希望能从台积电预订一条单独的生产线,用于生产他们的CPU和GPU,就像台积电与苹果之间的合作一样。但台积电方面希望英特尔为预订3nm工艺生产线支付预付款。据上证报报道,随着元宇宙“炒房”的大火,以NFT为代表的虚拟资产成为市场追逐元宇宙的又一题材。不过,有业内人士强调,当前元宇宙市场仍处于早期概念阶段,投资者应保持谨慎和理性。与元宇宙“炒房”相关的社交产品“虹宇宙”,也在官方微博多次发文称要严查炒作行为,提醒用户谨防上当受骗。据新华社报道,国际货币基金组织(IMF)15日发布的数据显示,受新冠疫情和全球经济衰退影响,2020年全球债务规模达到创纪录的226万亿美元。2020年是自第二次世界大战结束以来全球债务增加最多的一年,全球债务与国内生产总值(GDP)之比上升28个百分点至256%。其中,发达经济体公共债务上升尤为明显,其与GDP之比已从2007年的约70%升至2020年的124%。

Fiel a nuestra cita mensual, y sin que el coronavirus dichoso nos afecte, hoy lanzamos el séptimo programa de la tercera temporada de nuestro podcast, para que estéis enterados de toda la actualidad del mundo de los videojuegos y de los temas más candentes que han sucedido estos días. Teníamos ganas de una buena charla y mucho de lo que hablar, y por eso este programa ha quedado más largo de lo normal, casi dos horas, que esperamos podáis agradecer para sobrellevar mejor estos días de cuarentena. Dreams, las mejores parejas y la consola que nos robó el corazón Empezamos el programa repasando las noticias más importantes de estos últimos días, donde hablamos de Call of Duty: Warzone, la llegada de Horizon Zero Dawn a PC, los rumores de Sony tratando de hacerse con los derechos de Silent Hill, la demo de Resident Evil 3 y las novedades en Xbox Game Pass. En la noticia de la semana iniciamos una charla/debate sobre todo lo que hemos conocido de Xbox Series X y PlayStation 5, y es que las dos consolas de nueva generación han mostrado sus detalles técnicos y ya podemos compararlas. Analizamos su CPU/GPU, su memoria, sus características y añadidos, incluso nos atrevemos a apostar por su fecha y precio. ¿Acertará alguien? En la sección de El Recomendado de Allgamersin os dejamos varios juegos largos para que esta cuarentena por el COVID-19 se haga más llevadera, títulos que os ofrecerán decenas, incluso cientos de horas de juego y diversión. Finalmente en La Polémica hablamos de la extraña presentación de Sony con PS5 y la forma que está teniendo la compañía japonesa por ir ofreciendo la información de su consola en lo que va del año.

丽莎老师讲机器人之选择人工智能数据存储的六个注意事项欢迎收听丽莎老师讲机器人,想要孩子参加机器人竞赛、创意编程、创客竞赛的辅导,找丽莎老师!欢迎添加微信号:153 5359 2068,或搜索微信公众号:我最爱机器人。人工智能和机器学习将成为帮助企业利用其核心数字资产创造竞争优势的两个最重要的工具。但在采用人工智能数据存储之前,企业必须考虑一系列基于机器学习平台如何获取、处理和保留数据的需求。首先,企业需要检查机器学习软件使用的数据的生命周期,因为这可以帮助企业了解为人工智能选择存储时应考虑的事项。企业必须获取数据来训练机器学习或人工智能算法。这些是处理数据以学习任务的软件工具,例如识别对象、处理视频和跟踪运动。数据可以从多种来源产生,并且通常本质上是非结构化的,例如对象和文件。人工智能的训练过程需要使用数据资产,并使用机器学习或人工智能软件创建算法,以处理未来的数据源。在训练或开发算法时,人工智能软件将处理源数据,以开发一个模型,该模型可以创建企业需要获得的洞察力或收益。开发机器学习算法很少作为一个单一的过程来完成。随着企业积累新的数据,其算法得到了改进和完善。这意味着很少的数据被丢弃,相反,它会随着时间的推移而增长并重新处理。在企业为人工智能平台选择存储之前,必须首先考虑以下注意事项:1.成本。人工智能数据存储的成本是企业考虑的关键因素。显然,企业管理层和参与采购决策的管理人员都希望其存储尽可能具有成本效益,并且在许多情况下,这将影响企业的产品选择和策略。2.可扩展性。在此需要强调收集、存储和处理大量数据以创建机器学习或人工智能模型的必要性。机器学习算法要求源数据呈指数增长,以实现精度的线性提高。创建可靠和准确的机器学习模型可能需要数百TB甚至PB的数据,而且这只会随着时间的推移而增加。构建PB级存储系统通常意味着使用对象存储或横向扩展文件系统。现代对象存储当然可以解决人工智能工作负载的容量需求,但是它们可能无法满足其他标准,例如高性能。横向扩展文件系统可以提供高性能和良好的可扩展性,但是将整个数据集存储在单个平台上可能会很昂贵。由于可扩展性要求和大容量产品的成本,块存储通常不是机器学习或人工智能的正确选择,因为高容量产品的可扩展性要求和成本。这里唯一的例外是在公共云中。存储成本的变化引入了分层或使用多种存储类型来存储数据的思想。例如,对象存储是存储大量非活动人工智能数据的良好目标。当需要处理数据时,可以将其移动到高性能文件存储集群或为高性能而设计的对象存储中的节点,并且在处理完成后可以将数据移回。3.性能。人工智能数据的存储性能包括三个方面。首先可能也是最重要的是延迟。这定义了软件发出的每个I/O请求的处理速度。低延迟很重要,因为改善延迟会直接影响创建机器学习或人工智能模型所需的时间。复杂的模型开发可能需要数周或数月的时间才能运行。通过缩短此开发周期,企业可以更快地创建和完善模型。在检查延迟功能时,由于对象访问的数据流特性,对象将引用时间存储到第一个字节,而不是单个I/O请求的延迟。存储性能的另一个方面是吞吐量,这是可以将数据写入存储平台或从存储平台读取数据的速度。系统吞吐量很重要,因为人工智能培训会处理大量数据集,通常会反复读取和重新读取相同的数据以准确地开发模型。机器学习和人工智能数据的来源(例如自动驾驶汽车上的传感器)每天可以产生数TB的新数据。所有这些信息都必须添加到现有数据存储中,并且对任何现有处理的影响最小。正确设置存储平台至关重要,因为涉及的数据量非常大。存储性能的最后一个方面是并行访问。机器学习和人工智能算法并行处理数据,运行多个任务,这些任务可以多次读取同一数据,并跨越多个并行任务。对象存储擅长并行读取I/O处理,因为没有对象锁定或属性可管理。文件服务器跟踪内存中打开的I/O请求或文件句柄。因此,I/O请求的数量取决于平台上可用的内存。机器学习的数据可以由大量的小文件组成。在这个领域,文件服务器可以提供比对象存储更好的性能。向人工智能存储供应商提出的一个关键问题是,其产品的性能特征将如何在大文件类型和小文件类型之间发生变化。4.可用性和耐用性。机器学习和人工智能学习模型可以长期连续运行。通过训练开发算法可能需要几天或几周的时间。在此期间,存储系统必须启动并持续可用。这意味着任何升级、技术更换或系统扩展都需要在不停机的情况下进行。在大型系统中,部件故障是正常的,必须按此处理。这意味着用于人工智能工作的任何平台都应该能够从设备(例如HDD硬盘或SSD硬盘)和节点或服务器故障中恢复。对象存储使用擦除编码在多个节点上广泛分布数据,并将组件故障的影响降到最低。有擦除编码技术可以扩展文件系统以提供同等的弹性级别。擦除编码方案的效率非常重要,因为它直接关系到读写I/O的性能,特别是对于小文件。由于大多数大型对象存储太大而无法定期备份,因此可靠的擦除编码成为人工智能存储平台的基本功能。5.公共云。开发机器学习和人工智能算法既需要高性能的存储又需要高性能的计算。许多人工智能系统都基于GPU(例如Nvidia DGX),可以减轻开发精确算法所涉及的许多复杂数学计算的负担。公共云服务提供商已开始提供可用于机器学习的GPU加速虚拟实例。在公共云中运行机器学习工具可以降低构建机器学习开发基础设施的投资和成本,同时提供扩展开发机器学习模型所需基础设施的能力。使用公共云计算面临的挑战是如何以经济高效和实用的方式将数据导入公共云。基于云计算的对象存储速度太慢,无法满足机器学习的I/O需求;因此,必须使用本地块存储。每延迟一分钟传输数据以及执行机器学习的延迟,就意味着增加运行基础设施的成本。公共云的另一个问题是数据出口的成本。尽管云计算服务提供商不收取将数据移动到其平台的费用,但他们确实会收取从其平台之外的公共网络访问的任何数据的费用。因此,尽管公共云在计算方面提供了灵活性,但以一种及时且经济高效的方式在云中进出数据并不总是那么简单。供应商正在开发存储产品,以在其内部部署和公共云中运行其产品。这些产品可以有效地复制数据或将数据移至云中,并且只在完成后才将结果移回。这些复制技术具有高带宽效率,使在本地存储数据并导入到云中进行分析工作变得切实可行。6. 整合。构建人工智能数据存储可能很困难,因为存储网络和调整存储必须考虑其他因素才能与机器学习应用程序一起工作。产品的预包装使供应商能够在将产品交付给客户之前对其产品进行测试和优化。如今,有一些存储产品将流行的人工智能软件、通用CPU和GPU等计算、网络和存储设备结合在一起,以提供支持人工智能的平台。在部署这些系统之前,许多详细的调整工作已完成。尽管成本可能是一个问题,但对于许多客户而言,预包装的系统可以减少采用人工智能存储的障碍。显然,选择合适的人工智能数据存储平台是性能、可扩展性和成本等指标的平衡。正确使用存储平台至关重要,因为涉及的数据量很大。选择错误的产品可能是一个代价高昂的错误。与任何存储产品决策一样,重要的是与供应商沟通,以准确了解他们的产品如何满足人工智能和机器学习的需要。

Crypto and Blockchain Talk - Making You Smarter

  Blockchains and Algorithms   Blockchain is the latest tech craze and has attracted a lot of attention. Before blockchain, computers operated in a client/server relationship, where one central authority (the server) is contacted by a client (your laptop, phone, etc.) and is requested to send back information. An example of this is when you use Netflix. Your TV connects to a Netflix server, which has preloaded movies and shows for you to choose from. Once you select your show, it then streams the video content to you. That’s fine, until Netflix removes the show you want to watch, and you let out a big sigh. Well, it could be that their contract for sharing that show expired, or they needed the space to upload a new show. Either way, it is too bad for you.   What if there was infinite space, lots of bandwidth, anyone could upload a movie or TV show, and nobody was in charge, so your favorite show could never get removed? Sounds too good to be true, right? Well, that’s essentially what blockchain is: A network of ordinary computers, sharing resources, all working together with no master. The only control is the code shared by all these computers, which make the blockchain.   Every blockchain (network of computers) is designed to do something different. There are video distribution service blockchains being created right now, but there are many different uses for this technology, and ways to go about creating this network. No one way is perfect right now, and there is a huge race to evolve into the best overall solution. To have a blockchain, computers called miners must create new blocks which are then accepted or rejected by the network. Blocks are rejected if they are invalid, malicious, or incomplete. There have to be certain rules and guidelines set in place in order for the network to function properly. It wouldn’t make sense if a Netflix blockchain suddenly allowed someone to upload a book, or even a podcast, or upload a movie claiming themselves as the director or producer.   Here’s a brief overview of the Top 10 most used algorithms, and a sample of which popular blockchains use them:   Proof of Work - Bitcoin, Ethereum, and Monero Bitcoin’s founder created Proof of Work, where miners configure their computers to solve very intense puzzles, competing to create the next block. When they solve that puzzle (once every 10 minutes), they are given a reward (coins). Bitcoin has become so valuable, entire countries are setting up huge factories to create blocks and claim rewards. Places that have free power have a tremendous advantage, as the machines required to mine these blocks suck up unbelievable amounts of power. A decommissioned power plant in Australia was recently purchased solely for the purpose of Bitcoin mining. Video cards from NVIDIA and AMD have also been in exceptional demand. They are selling above MSRP, often sold out the same day a retailer has them in stock. Proof of Stake - NEO, DASH, and NavCoin Instead of mining, people who hold the coins belonging to the network have the option of being “minters”. A designated third party creates the blocks, then the minters run software on their computers that act as validators. It’s much less energy intensive and requires no special hardware, just coins. The more coins you have “staked” in the blockchain, the higher the chance you have at being selected (at random) to validate a block. Delegated Proof of Stake - EOS, Bitshares, and Lisk There is a major difference in this system compared to the previous two listed. Instead of everybody having a chance at validating a block, only a small number of machines on the network are selected, by a vote. This way, it is much easier for a handful of computers to talk to one another to compare blocks and validation, in a much more efficient way. If one validator starts to fail, they are voted out of circulation and replaced by another computer on the network. Instead of miners competing with each other, in DPoS they all work together to solve the block puzzle, creating blocks much, much faster. Proof of Authority - POA Network, Ethereum’s Kovan Testnet This consensus algorithm is pretty much the same as the client/server relationship. There is one authority in charge of everything, and the clients can just read the information (if allowed). This is best used in private corporate chains. Additional conditions to become an authority can be specified, including identity management and verification, in contrast to the previously mentioned algorithms, where the only identity on the network is often a wallet address or IP address/port. Proof of Activity - Decred This is a combination of both PoW and PoS. Currently only Decred uses it. Pros and Cons remain to be seen. Proof of Burn - Binance Coin, Counterparty, Slimcoin Instead of being rewarded for solving puzzles, you are supposed to send coins to an irretrievable address, to be lost forever. The concept is by decreasing the supply of coins, the value of the remaining ones increase. More often than not, the practice of “burning” coins is something done by the developers rather than the community. Blockchain ICOs often burn any unsold tokens remaining, as they cannot be allocated to any other area in an honest way. Binance burns some of its profits every quarter, to ensure its coin gains value. Proof of Elapsed Time - Hyperledger Sawtooth Every participant in the network is assigned a random time in each block. Whoever’s time runs out first, gets to create the next block. Clients on this network must be identified, and their code must have passed verification trust, to avoid simply exploiting the time on your network node to trigger sooner. Pros and cons are yet to be determined. Directed Acyclic Graph - IOTA, Hashgraph, and Nano Participants in this network that want to send a transaction, are first required to do a small proof of work, in which they verify two previous transactions that occurred before. In theory, this tangle can accelerate to near-instant speeds. Unlike traditional servers, the more users that are logged on, it gets faster instead of slower. Each of the networks has their own unique take on how to organize transactions, so read into each project more if you desire. Byzantine Fault Tolerance - Ripple, Stellar, and Dispatch Pre-selected validators are in charge of the network. No miners or community contributors are required. With that said, Stellar allows anyone to become a validator, while Ripple itself decides who validates blocks on their network. These are centralized services using blockchain technology. Proof of Space/Capacity - Burst Although, only one coin currently uses this, it is a fantastic algorithm. It allows people to mine using spare hard drive space, instead of CPU/GPU cycles. Your hard drive space is filled up with small amounts of random files that act like lottery tickets. The network elects a winner every defined number of seconds (or minutes) and gives them a coin reward. It takes tiny fractions of energy (5 watts) to power a hard drive, compared to 100+ watts of a single GPU or 1200+ watts of an ASIC (specialized mining hardware developed just for Bitcoin and other major coins).   There are still many more algorithms out there, including:   Proof of Importance Proof of Reputation Proof of Weight Proof of Evolution Tendermint CASPER Distributed Byzantine Fault Tolerance SPECTRE   If you’re thinking of creating a blockchain of your own, continue your research!

Allan’s recap of the ZFS User conference, first impressions of OmniOS by a BSD user, Nextcloud 13 setup on FreeBSD, OpenBSD on a fanless desktop computer, an intro to HardenedBSD, and DragonFlyBSD getting some SMP improvements. Headlines ZFS User Conference Recap Attendees met for breakfast on the fourth floor, in a lunchroom type area just outside of the theatre. One entire wall was made of lego base plates, and there were buckets of different coloured lego embedded in the wall. The talks started with Matt Ahrens discussing how the 2nd most requested feature of ZFS, Device Removal, has now landed, then pivoting into the MOST requested feature, RAID-Z expansion, and his work on that so far, which included the first functional prototype, on FreeBSD. Then our friend Calvin Hendryx-Parker presented how he solves all of his backup headaches with ZFS. I provided him some helpful hints to optimize his setup and improve the throughput of his backups Then Steven Umbehocker of OSNEXUS talked about their products, and how they manage large numbers of ZFS nodes After a very nice lunch, Orlando Pichardo of Micron talked about the future of flash, and their new 7.5TB SATA SSDs. Discussion of these devices after the talk may lead to enhancements to ZFS to better support these new larger flash devices that use larger logical sector sizes. Alek Pinchuk of Datto talked about Pool Layout Considerations then Tony Hutter of LLNL talked about the release process for ZFS on Linux Then Tom Caputi of Datto presented: Helping Developers Help You, guidance for users submitting bug reports, with some good and bad examples Then we had a nice cocktail party and dinner, and stayed late into the night talked about ZFS The next day, Jervin Real of Percona, presented: ZFS and MySQL on Linux, the Sweet Spots. Mostly outlining some benchmark they had done, some of the results were curious and some additional digging may turn up enhancements that can be made to ZFS, or just better tuning advice for high traffic MySQL servers. Then I presented my ZSTD compression work, which had been referenced in 2 of the previous talks, as people are anxious to get their hands on this code. Lastly, Eric Sproul of Circonus, gave his talk: Thank You, ZFS. It thanked ZFS and its Community for making their companies product possible, and then provided an update to his presentation from last year, where they were having problems with extremely high levels of ZFS fragmentation. This also sparked a longer conversation after the talk was over. Then we had a BBQ lunch, and after some more talking, the conference broke up. Initial OmniOS impressions by a BSD user I had been using FreeBSD as my main web server OS since 2012 and I liked it so much that I even contributed money and code to it. However, since the FreeBSD guys (and gals) decided to install anti-tech feminism, I have been considering to move away from it for quite some time now. As my growing needs require stronger hardware, it was finally time to rent a new server. I do not intend to run FreeBSD on it. Although the most obvious choice would be OpenBSD (I run it on another server and it works just fine), I plan to have a couple of databases running on the new machine, and database throughput has never been one of OpenBSD's strong points. This is my chance to give illumos another try. As neither WiFi nor desktop environments are relevant on a no-X11 server, the server-focused OmniOS seemed to fit my needs. My current (to be phased out) setup on FreeBSD is: apache24 with SSL support, running five websites on six domains (both HTTP and HTTPS) a (somewhat large) Tiny Tiny RSS installation from git, updated via cronjob sbcl running a daily cronjob of my Web-to-RSS parser an FTP server where I share stuff with friends an IRC bouncer MariaDB and PostgreSQL for some of the hosted services I would not consider anything of that too esoteric for a modern operating system. Since I was not really using anything mod_rewrite-related, I was perfectly ready to replace apache24 by nginx, remembering that the prepackaged apache24 on FreeBSD did not support HTTPS out of the box and I had ended up installing it from the ports. That is the only change in my setup which I am actively planning. So here's what I noticed. First impressions: Hooray, a BSD boot loader! Finally an operating system without grub - I made my experiences with that and I don't want to repeat them too often. It is weird that the installer won't accept "mydomain.org" as a hostname but sendmail complains that "mydomain" is not a valid hostname right from the start, OmniOS sent me into Maintenance Mode to fix that. A good start, right? So the first completely new thing I had to find out on my new shiny toy was how to change the hostname. There is no /etc/rc.conf in it and hostname mydomain.org was only valid for one login session. I found out that the hostname has to be changed in three different files under /etc on Solaris - the third one did not even exist for me. Changing the other two files seems to have solved this problem for me. Random findings: ~ I was wondering how many resources my (mostly idle) new web server was using - I always thought Solaris was rather fat, but it still felt fast to me. Ah, right - we're in Unixland and we need to think outside of the box. This table was really helpful: although a number of things are different between OmniOS and SmartOS, I found out that the *stat tools do what top does. I could probably just install top from one of the package managers, but I failed to find a reason to do so. I had 99% idle CPU and RAM - that's all I wanted to know. ~ Trying to set up twtxt informed me that Python 3.6 (from pkgin) expects LANG and LC_ALL to be set. Weird - did FreeBSD do that for me? It's been a while ... at least that was easy to fix. ~ SMF - Solaris's version of init - confuses me. It has "levels" similar to Gentoo's OpenRC, but it mostly shuts up during the boot process. Stuff from pkgsrc, e.g. nginx, comes with a description how to set up the particular service, but I should probably read more about it. What if, one day, I install a package which is not made ready for OmniOS? I'll have to find out how to write SMF scripts. But that should not be my highest priority. ~ The OmniOS documentation talks a lot about "zones" which, if I understand that correctly, mostly equal FreeBSD's "jails". This could be my chance to try to respect a better separation between my various services - if my lazyness won't take over again. (It probably will.) ~ OmniOS's default shell - rather un-unixy - seems to be the bash. Update: I was informed about a mistake here: the default shell is ksh93, there are bogus .bashrc files lying around though. ~ Somewhere in between, my sshd had a hiccup or, at least, logging into it took longer than usual. If that happens again, I should investigate. Conclusion: By the time of me writing this, I have a basic web server with an awesome performance and a lot of applications ready to be configured only one click away. The more I play with it, the more I have the feeling that I have missed a lot while wasting my time with FreeBSD. For a system that is said to be "dying", OmniOS feels well-thought and, when equipped with a reasonable package management, comes with everything I need to reproduce my FreeBSD setup without losing functionality. I'm looking forward to what will happen with it.

News Roundup Nextcloud 13 on FreeBSD Today I would like to share a setup of Nextcloud 13 running on a FreeBSD system. To make things more interesting it would be running inside a FreeBSD Jail. I will not describe the Nextcloud setup itself here as its large enough for several blog posts. Official Nextcloud 13 documentation recommends following setup: MySQL/MariaDB PHP 7.0 (or newer) Apache 2.4 (with mod_php) I prefer PostgreSQL database to MySQL/MariaDB and I prefer fast and lean Nginx web server to Apache, so my setup is based on these components: PostgreSQL 10.3 PHP 7.2.4 Nginx 1.12.2 (with php-fpm) Memcached 1.5.7 The Memcached subsystem is least important, it can be easily changed into something more modern like Redis for example. I prefer not to use any third party tools for FreeBSD Jails management. Not because they are bad or something like that. There are just many choices for good FreeBSD Jails management and I want to provide a GENERIC example for Nextcloud 13 in a Jail, not for a specific management tool. Host Lets start with preparing the FreeBSD Host with needed settings. We need to allow using raw sockets in Jails. For the future optional upgrades of the Jail we will also allow using chflags(1) in Jails. OpenBSD on my fanless desktop computer You asked me about my setup. Here you go. I’ve been using OpenBSD on servers for years as a web developer, but never had a chance to dive in to system administration before. If you appreciate the simplicity of OpenBSD and you have to give it a try on your desktop. Bear in mind, this is a relatively cheap ergonomic setup, because all I need is xterm(1) with Vim and Firefox, I don’t care about CPU/GPU performance or mobility too much, but I want a large screen and a good keyboard.

I prefer slow fashion. iXsystems iX Ad Spot NAB 2018 – Michael Dexter’s Recap Introduction to HardenedBSD World HardenedBSD is a security enhanced fork of FreeBSD which happened in 2014. HardenedBSD is implementing many exploit mitigation and security technologies on top of FreeBSD which all started with implementation of Address Space Layout Randomization (ASLR). The fork has been created for ease of development. To cite the https://hardenedbsd.org/content/about page – “HardenedBSD aims to implement innovative exploit mitigation and security solutions for the FreeBSD community. (…) HardenedBSD takes a holistic approach to security by hardening the system and implementing exploit mitigation technologies.” Most FreeBSD enthusiasts know mfsBSD project by Martin Matuska – http://mfsbsd.vx.sk/ – FreeBSD system loaded completely into memory. The mfsBSD synonym for the HardenedBSD world is SoloBSD – http://www.solobsd.org/ – which is based on HardenedBSD sources. One may ask how HardenedBSD project compared to more well know for its security OpenBSD system and it is very important question. The OpenBSD developers try to write ‘good’ code without dirty hacks for performance or other reasons. Clean and secure code is most important in OpenBSD world. The OpenBSD project even made security audit of all OpenBSD code available, line by line. This was easier to achieve in FreeBSD or HardenedBSD because OpenBSD code base its about ten times smaller. This has also other implications, possibilities. While FreeBSD (and HardenedBSD) offer many new features like mature SMP subsystem even with some NUMA support, ZFS filesystem, GEOM storage framework, Bhyve virtualization, Virtualbox option and many other new modern features the OpenBSD remains classic UNIX system with UFS filesystem and with very ‘theoretical’ SMP support. The vmm project tried to implement new hypervisor in OpenBSD world, but because of lack of support for graphics its for OpenBSD, Illumos and Linux currently, You will not virtualize Windows or Mac OS X there. This is also only virtualization option for OpenBSD as there are no Jails on OpenBSD. Current Bhyve implementation allows one even to boot latest Windows 2019 Technology Preview. A HardenedBSD project is FreeBSD system code base with LOTS of security mechanisms and mitigations that are not available on FreeBSD system. For example entire lib32 tree has been disabled by default on HardenedBSD to make it more secure. Also LibreSSL is the default SSL library on HardenedBSD, same as OpenBSD while FreeBSD uses OpenSSL for compatibility reasons. Comparison between LibreSSL and OpenSSL vulnerabilities. https://en.wikipedia.org/wiki/LibreSSL#Security https://wiki.freebsd.org/LibreSSL#LibreSSL.28andOpenSSL.29SecurityVulnerabilities One may see HardenedBSD as FreeBSD being successfully pulled up to the OpenBSD level (at least that is the goal), but as FreeBSD has tons more code and features it will be harder and longer process to achieve the goal. As I do not have that much competence on the security field I will just repost the comparison from the HardenedBSD project versus other BSD systems. The comparison is also available here – https://hardenedbsd.org/content/easy-feature-comparison – on the HardenedBSD website.

最近一段时间有一个与科技相关的重大热点话题,就是中国的中兴通讯公司被美国禁售的事件,好多听众都来问我对这事怎么看?我国为什么都已经厉害了,但是芯片却还是罩门呢?我想,既然是做节目,还是要简单介绍一下中兴通讯被美国禁售是怎么回事。2018 年 4 月 16 日,美国的商务部下达了对中兴长达七年的禁售令,这个禁售包含两部分意思。一是禁止美国公司向中兴公司出售任何有技术含量的软硬件,准确地说这个出售是广义的,免费赠送也算是出售,用商务部的原话就是不得订购、买卖、使用、送交、存储、交易、转让、运输,包括开源的安卓系统中兴也不能用,因为安卓是谷歌的,说的通俗点就是只要是美国货,中兴公司连碰都不能碰。另一层含义是中兴公司的产品不能在美国销售。可能大家没想到,2017 年的最新数据显示,中兴的手机是墙内开花墙外香,中兴手机在美国的市场份额排名第四,占 11.6%,排在苹果、三星、LG 之后,排名第一的苹果大约是中兴的三倍,中兴手机在美国的出货量大约是 460 万台。禁令是即时生效的,所以也就意味着,从禁令下达的当天开始,中兴原计划销往美国的手机瞬间就变成几乎不值一文的库存了。这个打击对中兴来说是休克性的,中兴的股票也马上就停牌了。在中兴工作的据说八万名员工瞬间不知道该干什么了,当然这是比较夸张的说法,中兴的产品线也并不是完全依赖美国货。我相信在这种公司的危难时刻,一定还是会有大量的中兴员工同心协力、共渡难关的。那这次美国人为什么下手这么狠呢,原因到底是什么?根据美国商务部的文件,是这么说的,中兴公司违反了 2016 年与美国商务部的一份调解协议,当时中兴公司因为违反了美国商务部关于美国产品的出口限制条例,违规将含有美国技术的产品出售给伊朗等国家,所以美国商务部对中兴实施了 8 亿多美元的处罚,其中有 3 亿美元缓期执行,但前提是中兴公司要承诺做到很多事情,如果不能做到,那就会遭到长达 7 年的禁售令。结果中兴公司实际上没有按照协议规定开除 35 名高管,被美国抓住了证据,于是美国商务部就按照当初的协议下达了禁售令。大致来说就是这样一个过程。我相信详细的具体过程肯定是非常复杂的,中兴公司也一定会有自己的理由。那这中间的是非功过我没有资格去评说,也不是我这个节目的宗旨,我只是把事件的背景给听众们交代一下。这件事情,我想,会给很多并不理性的爱国者上了一课,那些整天用一种很极端的方式号召抵制美货的人在我看来就并不是十分理性的,这次事件,就告诉他们,有些产品,我们买不到才是更大的悲剧。我们总不能一边高喊抵制美货,一边又骂美国人不卖东西给我们吧,这种情况是很矛盾的。同时,这件事情也让很多普通中国人吃了一惊,原来在市场经济中,也并不都是顾客就是上帝啊。可能有很多人都觉得现在这个时代甲方都是腰杆子最硬的,谁有钱谁有底气,只有卖货的求着买货的,哪有买家求着卖家的道理呢。在我们作为个人的日常消费中,确实是这样的。但是在世界贸易的大格局中,尤其是涉及到高科技产品的贸易中,其实并不都是这样。大家可能不知道,很多中国公司,包括中兴、华为这样的大公司,拿着钱去买美国、德国、日本等国家的高技术含量的产品时,那都是要低三下四,有时候还要通过一些有活动能力的中间人才能买到。即便买到了,也必须签署同意非常多的附加条件。但也有很多情况下,我国的公司费了很大的周折,填写了大量调查表格,受尽了屈辱后,人家回一封邮件,写道:很抱歉,我们不能将该产品卖给贵公司。有时候,中国的公司花很高的价钱去收购国外一家负资产的公司,可能就是为了这家公司拥有的某一台先进的设备或者某个有研发能力的团队。我们经常说,钱买不来知识、人品、气质等等非物质层面的东西。实际上,有时候,连物质层面的科技产品也是没法用钱买来的。其中,最最重要的高科技产品就是芯片——一块小小的集成电路。它的原料就是一把沙子,提纯成单晶硅后,在上面刻上成千上亿个半导体单元,就是我国现在面临的一道高高的技术门槛,如果我们不能自己迈过去,就有可能遭到别国一剑封喉式的打击。芯片到底是怎么做出来的呢?一块芯片的诞生,要经历设计、制造、封装、测试四个阶段,缺一不可,越是前面的步骤技术含量就越高,越往后就相对容易一些。中国和美国目前最大的差距就在芯片的设计上,这种差距是全方位的差距,不但有技术本身,还有人家先发的专利保护优势。芯片设计本身又要分成很多个层次,最基础的层次就是指令集架构,相当于建楼房的基本框架结构,这种框架结构目前百分之一百掌握在美国人的手上。在框架结构上继续细化的设计中国和美国、日本、德国的差距也很大。如果从销售额上来说,中国的紫光公司是中国最大的芯片设计企业,可是它目前也仅仅具备设计内存芯片的能力。从先进性上来说,华为的海思麒麟芯片是中国自主研发的最高成就了,不过,它依然是建立在美国人搞出来的 ARM 框架下,当然用别人的框架还有很多其他复杂的因素,并不仅仅是技术因素,但技术因素也是最重要的因素之一。还有,麒麟芯片中非常至关重要的数字信号处理器 DSP 买的是美国德州仪器的技术,华为还研发不出替代品。所以,如果美国对华为也禁售,那么理论上,华为的麒麟芯片也无法生产了。除了手机芯片我们勉强还能算有自主研发能力外,其他广泛使用的民用领域芯片,例如 CPU、GPU等等,我们几乎都还是空白。芯片的设计图出来了,就要进入到制造环节,如果制造技术跟不上,设计的再好也不行。衡量制造水平的高低有一个最重要的参数,就是芯片半导体单元的密度,这个一般用多少纳米来衡量。这个领域最强的是美国、中国台湾和韩国。中国大陆目前具备的最先进的生产线是 28nm 的,但是国际最先进的已经小于 10nm 了,我们还与国际先进水平有至少两代的差距,我这还是用的中国的最好的水平跟国际上的平均水平比,如果跟他们最先进的去比,那差距就更大。总之,我们在制造领域的差距,业内人士都知道,也是非常巨大的。如果台湾能回归祖国的话,这一块的差距倒是可以瞬间抹平,只是台湾问题就更复杂了。相比设计和制造,我们在封装和测试这两个环节上的差距倒是并不大,甚至在工厂规模上还远超美国,但工厂规模还是不能代表技术,用到的设备和技术依然还严重依赖进口。总之,如果大家看到有些乐观主义的文章说,设计制造芯片也没什么了不起的,技术没那么神秘,只要愿意投入研发资金,搞出来并不难,这么说是不客观的,如果真这么容易,中国早就搞出来了。用大炼钢铁的精神去搞芯片也就是历史重演罢了。有些人在谈论中国的成就和世界的地位时,往往眼里只有 GDP,尤其是在谈到日本时,总是拿 GDP 来嘲笑他们发展停滞了,可是,如果从科技的发展来看,日本不但没有停滞,还把中国甩在了后面。我觉得,中国人在对待发展这个问题上,我们也需要一次认知升级,我们不能再只盯着 GDP 来与世界各国比较了,我们还要跟他们比全民的科学素养、科技企业的软实力、科研体制的活力和全民对科学活动的重视程度。在这次中兴事件后,我也看了大量的评论文章。有两种倾向我都是反对的,一个是速胜论,以为我们只要拿出铁人的牺牲精神,不怕苦不怕累,咬紧牙关就能在三五年内打破国外的技术垄断。还有一个是亡国论,从一个芯片技术的落后就全面否定我国这三十年来在科技发展上取得的所有重大成果。我国的军事技术、航空航天技术、巨型计算机、量子通信、超级工程建设技术等等,那也都是实打实的取得了巨大的进步,该有的自信我们绝不能丢掉,要相信中华民族的伟大复兴迟早会到来。我做了那么多期节目,今天是第一次在节目中喊了一次口号,那是看了很多亡国论的文章实在忍不住了。但是,我其实心理很清楚,喊口号其实是最没有实际作用的做法。芯片很难做,无论是设计、制造还是封装,都有非常高的技术含量,也没办法靠几个归国的高级人才就能解决。它是一个国家综合科技实力的体现,是一个国家在厚厚的土壤上才能成长出来的花朵,要想造出好芯片,要从娃娃抓起。全民科学素养就是这层厚厚的土壤。我们与美国的真正差距就是这层土壤的差距。在面对中兴禁售事件中,有些人高喊着口号,有些人痛骂着国民劣根性。也有一些人,默默地咬紧牙关,用自己力所能及的点滴工作为我国的科技发展做一些贡献。而我,通过中兴事件,越发感到自己正在进行的这项科普事业的重大意义,我虽然不能直接为中国今天的科研起到促进作用,但是我在做的是默默地耕耘土壤的工作,或许,明天中国取得的科技成就会有我的点滴贡献,我今天就像是一个农民,为了这片土壤的肥沃,辛勤地翻土、浇水、施肥,这些工作说实话并没有太多的技术含量,只是一些体力活,但这种工作也必须要有人做,一片茂盛庄稼的诞生,每一个环节都需要做好。而你作为我的听众,或许正在竖立世界观的过程中,或许正在选择未来攻读的方向,也或许是年轻的父母,我想,我们都少喊一点口号,少骂几声娘,咬紧牙关,志存高远,或许我们今天的努力,可以让中华民族的伟大复兴早一秒钟到来。

In machine learning, training large models on massive amount of data usually improved results. Our customers report, however, that training such models and deploying them is either operationally prohibitive or outright impossible for them. Amazon AI Algorithms is designed to solve this problem. It is a collection of distributed streaming ML algorithms that scale to any amount of data. They are fast and efficient because they distribute across CPU/GPU machines and share a collective distributed state via a highly-optimized parameter server. They scale to an infinite amount of data because they operate in the streaming model. This means they require only one pass over the data and never increase their resources consumption, allowing training to be paused, resumed, and snapshotted and even for algorithms to consume kinesis streams directly providing an “always on” training mechanism.  They are production ready.  Trained models are automatically containerized and useable in production using Amazon SageMaker hosting. Finally, we provide a convenient SDK which allows scientists to create new algorithms which operate in this model and enjoy all the benefits above. This talk will discuss our design choices and some of the internal working of the system. It will also describe the distributed streaming model and its numerous benefits to machine learning practitioners. We will show how to invoke large scale learning from Amazon SageMaker, or Amazon EMR, and host the solution. Time permits, we will show how to develop a new Algorithm using the SDK.

This episode was brought to you by Headlines Alexander Motin implements CTL High Availability (https://svnweb.freebsd.org/changeset/base/r287621) CTL HA allows two .head. nodes to be connected to the same set of disks, safely An HA storage appliance usually consists of 2 totally separate servers, connected to a shared set of disks in separate JBOD sleds The problem with this setup is that if both machines try to use the disks at the same time, bad things will happen With CTL HA, the two nodes can communicate, in this case over a special TCP protocol, to coordinate and make sure they do not step on each others toes, allowing safe operation The CTL HA implementation in FreeBSD can operate in the following four modes: Active/Unavailable -- without interlink between nodes Active/Standby -- with the second node handling only basic LUN discovery and reservation, synchronizing with the first node through the interlink Active/Active -- with both nodes processing commands and accessing the backing storage, synchronizing with the first node through the interlink Active/Proxy -- with second node working as proxy, transferring all commands to the first node for execution through the interlink The custom TCP protocol has no authentication, so it should never be enabled on public interfaces Doc Update (https://svnweb.freebsd.org/base?view=revision&revision=287707) *** Panel Self-Refresh support lands in DragonFlyBSD (http://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/d13e957b0d66a395b3736c43f18972c282bbd58a) In what seems almost weekly improvements being made to the Xorg stack for DragonFly, we now have Panel Self-Refresh landing, thanks to Imre Vadász Understanding Panel Self-Refresh (http://www.anandtech.com/show/7208/understanding-panel-self-refresh) and More about Panel Self-Refresh (http://www.hardwaresecrets.com/introducing-the-panel-self-refresh-technology/) In a nutshell, the above articles talks about how in the case of static images on the screen, power-savings can be obtained by refreshing static images from display memory (frame-buffer), disabling the video processing of the CPU/GPU and associated pipeline during the process. And just for good measure, Imre also committed some further Intel driver cleanup, reducing the diff with Linux 3.17 (http://gitweb.dragonflybsd.org/dragonfly.git/commitdiff/6b231eab9db5ef4d4dc3816487d8e3d48941e0e2) *** Introducing Sluice, a new ZFS snapshot management tool (https://bitbucket.org/stevedrake/sluice) A new ZFS snapshot management tool written in Python and modeled after Apple.s Time Machine Simple command line interface No configuration files, settings are stored as ZFS user properties Includes simple remote replication support Can operate on remote systems with the zfs://user@host/path@snapname url schema Future feature list includes .import. command to moved files from non-ZFS storage to ZFS and create a snapshot, and .export. to do the inverse Thanks to Dan for tipping us about this new project *** Why WhatsApp only needs 50 engineers for 900 million users (http://www.wired.com/2015/09/whatsapp-serves-900-million-users-50-engineers/) Wired has a good write-up on the behind-the-scenes work taking place at WhatsApp While the article mentions FreeBSD, it spends the bulk of its discussion about Erlang and using its scalable concurrency and deployment of new code to running processes. FB messenger uses Haskell to accomplish much the same thing, while Google and Mozilla are currently trying to bring the same level of flexibility to Go and Rust respectively. video (https://www.youtube.com/watch?v=57Ch2j8U0lk) Thanks to Ed for submitting this news item *** Interview - Aaron Poffenberger - email@email (mailto:akp@hypernote.com) / @akpoff (https://twitter.com/akpoff) BSD in a strange place + KM: Go ahead and tell us about yourself and how did you first get involved with BSD? + AJ: You.ve presented recently at Texas Linux Fest, both on FreeBSD and FreeNAS. What specifically prompted you to do that? + KM: What would you say are the main selling points when presenting BSD to Linux users and admins? + AJ: On the flip side of this topic, in what areas to do you think we could improve BSD to present better to Linux users? + KM: What would you specifically recommend to other BSD users or fans who may also want to help present or teach about BSD? Any things specifically to avoid? + AJ: What is the typical depth of knowledge you encounter when presenting BSD to a mostly Linux crowd? Any surprises when doing so? + KM: Since you have done this before, are you mainly writing your own material or borrowing from other talks that have been done on BSD? Do you think there.s a place for some collaboration, maybe having a repository of materials that can be used for other BSD presenters at their local linux conference / LUG? + AJ: Since you are primarily an OpenBSD user have you thought about doing any talks related to it? Is OpenBSD something on the radar of the typical Linux conference-goer? + KM: Is there anything else you would like to mention before we wrap up? News Roundup GhostBSD 10.1 released (http://ghostbsd.org/10.1_release_eve) GhostBSD has given us a new release, this time it also includes XFCE as an alternative to the MATE desktop The installer has been updated to allow using GRUB, BSD loader, or none at all It also includes the new OctoPKG manager, which proves a Qt driven front-end to pkgng Thanks to Shawn for submitting this *** Moving to FreeBSD (https://www.textplain.net/blog/2015/moving-to-freebsd/) In this blog post, Randy Westlund takes us through his journey of moving from Gentoo over to FreeBSD Inspired in part due to Systemd, he first spent some time on Wikipedia reading about BSD before taking the plunge to grab FreeBSD and give it a whirl in a VM. "My first impression was that installation was super easy. Installing Gentoo is done manually and can be a "fun" weekend adventure if you're not sure what you're doing. I can spin up a new FreeBSD VM in five minutes." "There's a man page for everything! And they're well-written! Gentoo has the best documentation of any Linux distro I've used, but FreeBSD is on another level. With a copy of the FreeBSD Handbook and the system man pages, I can actually get things done without tabbing over to Google every five minutes." He goes on to mention everything from Init system, Jails, Security, Community and License, a well-rounded article. Also gives a nice shout-out to PC-BSD as an even easier way to get started on a FreeBSD journey, thanks! Shout out to Matt for tipping us to this blog post *** OpenBSD Enables GPT by default (https://marc.info/?l=openbsd-cvs&m=144190275908215&w=2) Looks like OpenBSD has taken the plunge and enabled GPT by default now Ken Westerback does us the honors, by removing the kernel option for GPT Users on -CURRENT should give this a whirl, and of course report issues back upstream Credit to Jona for writing in about this one *** DISCUSSION: Are reproducible builds worth-while? (http://www.tedunangst.com/flak/post/reproducible-builds-are-a-waste-of-time) In this weeks article / rant, Ted takes on the notion of reproducible builds being the end-all be-all for security. What about compiler backdoors? This does not prevent shellshock, or other bugs in the code itself Personally, I.m all in favor, another .Trust but verify. mechanism of the distributed binaries, plus it makes it handy to do source builds and not end up with various checksum changes where no code actually changed. *** Feedback/Questions David writes in (http://slexy.org/view/s20Q7XjxNH) Possnfiffer writes in (http://slexy.org/view/s2QtE6XzJK) Daniel writes in (http://slexy.org/view/s20uloOljw) ***
