Effektive Observability mit OpenTelemetryFrüher waren viele Applikationen eine Black Box, besonders für die Ops aka Betriebsabteilung. Dann fing das Logging an. Apps haben Log-Lines geschrieben, zum Beispiel wann die App fertig hochgefahren ist oder wenn etwas schief gegangen ist. In einer Art und Weise haben durch Logs die Devs angefangen, mit den Ops-Leuten zu kommunizieren.Irgendwann später gab es Metriken. Wie viel RAM verbraucht die App, wie oft wurde der Garbage Collector getriggert oder auch Business-Metriken, wie oft eine Bestellung ausgeführt wurde oder wann eine Geo- anstatt einer Text-Suche gestartet wurde.War das alles? Nein. Der neueste Hype: Traces. Eine genaue Einsicht, welchen Code-Path die App genommen hat und wie lange dieser gedauert hat inkl. aller Metadaten, die wir uns wünschen.Und wenn man dies nun alles in einen Sack packt, es gut durchschüttelt und man ein System hat, das man auf Basis dieser Daten fragen stellen kann, nennt man das Observability.Und genau da setzt das Projekt OpenTelemetry an.In dieser Episode sprechen wir mit dem Experten Severin Neumann über Observability und OpenTelemetry.Bonus: Was ist ein Sales-Engineer?**** Diese Episode wird gesponsert von www.aboutyou.de ABOUT YOU gehört zu den größten Online-Fashion Shops in Europa und ist immer auf der Suche nach Tech-Talenten - wie zum Beispiel einem (Lead) DevOps/DataOps Engineer Google Cloud Platform oder einem Lead Platform Engineer.

I've been told for a couple of years now that I'd love Katie Powner's books, so I've bought a couple, but now it's time to read it, and I think her most recent release, The Wind Blows in Sleeping Grass might just be the perfect choice for me. Listen in and see why! Note: links may be affiliate links that provide me with a small commission at no extra expense to you. What Do a Pig, a Garbage Collector, and an Elderly Woman Have in Common? I had a delightful chat with Katie Powner about writing, characters, her love of pigs, and even the Bible story about the demoniac of Gadarenes. Learning where she got the idea for a garbage-collecting prodigal and a pig named Pearl was only the highlight of the conversation. She also talked about her favorite kinds of books to read (she likes those that are still popular after the newness has worn off) and gave us recommendations for which of her books to start with based on the kind of book you're looking for. The Wind Blows in Sleeping Grass by Katie Powner For the first time in his life, Pete has everything to lose. After years of drifting, fifty-year-old Pete Ryman has settled down with his potbellied pig, Pearl, in the small Montana town of Sleeping Grass--a place he never expected to see again. It's not the life he dreamed of, but there aren't many prospects for a high-school dropout like him. Elderly widow Wilma Jacobsen carries a burden of guilt over her part in events that led to Pete leaving Sleeping Grass decades ago. Now that he's back, she's been praying for the chance to make things right, but she never expected God's answer to leave her flat on her face--literally--and up to her ears in meddling. When the younger sister Pete was separated from as a child shows up in Sleeping Grass with her eleven-year-old son, Pete is forced to face a past he buried long ago, and Wilma discovers her long-awaited chance at redemption may come at a higher cost than she's willing to pay.

But when I discovered Robert Gammal's book, The Garbage Collector, I learned that I had missed a huge part of the story.During a root canal procedure, the endodontist drills out the tooth's center. He then applies carcinogenic antiseptics such as phenol and formaldehyde in a futile attempt to sterilize it. Next, he fills it with a range of materials that are far from biocompatible. These toxic materials are described HERE, and all of them are considered safe and effective by the dental fraternity, the FDA, and the Therapeutic Goods Association of Australia. Any of these can pass into the brain, which is only a few inches away. Precisely filling the remaining hole where nerves went into a tooth's roots is impossible. So the dentist either leaves these open to the rest of the body or overfills it. In the past, this was often done using mercury alloys. Currently, other hazardous materials are used, but removing dead teeth with old amalgam-containing root canals is still part of any biological dentist's practice. Dr. Gammal's wrote me to say, “All root fillings leak and this gets worse over time. The other danger is that if the root canal is overfilled with toxic filling materials, it inevitably kills the bone around the end of the root. Mercury is sometimes still placed at the end of the root following the apicectomy procedure, and this is a total disaster.”Following a root canal, the tooth is no longer living but dead—it becomes a “foreign body.” A tooth is not a stone—it is human tissue. All surgeons know what happens when dead biological materials remain inside people. These are inevitably infected and spread bacteria to new locations. For example, nearly all heart attack artery blockages are infected with the same bacteria that are in the patient's mouth. Also, inflammatory diseases such as arthritis and other autoimmune conditions often go away when canal teeth are removed. Gammal editorializes:Nothing works. The whole procedure is based on illusion from beginning to end. If it were possible to sterilize the tooth, then this problem would not exist. There is a blanket denial that bacteria and toxins escape from the tooth the whole way down the length of the root, and not just through the apex. It would therefore make more sense to take the whole root out and not just the end of it. Fantasy and illusion reign in the minds of endodontists.NB: This introduction understates the harms of root canals. The rest of this post will document why they should never be performed and why they must be extracted.FOR MORE, SEE https://robertyoho.substack.com/p/259-i-thought-i-was-done-banging#detailsSupport the show

On today's episode, Chris and Andrew have an early start and catch up on their lives. Then, they dive deep into the latest developments in the Rails community, including the release of Rails 7.0.6, bug fixes, and changes to Active Record.  They share their experiences with GitHub deployments, documentation issues, and how they navigate through its challenges. They discuss the benefits of MySQL and Postgres, as well as the ongoing advancements in Postgres, specifically Crunchy Data's contributions.  Chris and Andrew share their views on working in different company sizes, the joys of learning new things, dealing with burnout, and the slower pace of feature shipping in larger companies. There's a discussion on Reddit's recent actions, its impact on subreddit moderations, and the discontinuation of the Reddit API. We'll also hear about Chris's cooking adventures, experimenting with different flavors, and making some Texas Twinkies.

Design of CPython’s Garbage Collector: https://devguide.python.org/garbage_collector/. Dificultades con el horario de la tertulia. Podría haber más tertulias en otros horarios, llevadas por otras personas. Problemas para publicar los audios. Editar es un infierno. Las notas de los audios tienen una importancia transcendental. Dinámica de las tertulias. Antiguo podcast "Python en español": https://podcast.jcea.es/python/. [08:32] Presentaciones. Raspberry Pi Pico: https://www.raspberrypi.org/products/raspberry-pi-pico/.

Issue9325: Add an option to pdb/trace/profile to run library module as a script https://bugs.python.org/issue9325. [16:27] Lo importante que es abrir bugs, para que puedan solucionarse. Queja productiva. [18:12] Nueva versión de MYPY http://mypy-lang.org/ y MYPYC https://github.com/mypyc/mypyc, que aprovechan Python 3.9. Sigue fallando mucho. [20:42] pyannotate https://pypi.org/project/pyannotate/ para meter anotaciones de tipos de forma automática. Las dificultades de meter tipos en un proyecto ya maduro. [22:52] Puedes usar tipos o no. Son opcionales. Ventajas en equipos grandes. Linter: https://es.wikipedia.org/wiki/Lint. Impone disciplina y una cultura. Las anotaciones de tipos no se verifican en tiempo de ejecución. Se usan en el sistema de test e integración continua. Una de la ventaja de los "__slots__" es que si te equivocas en el nombre de atributo en una asignación, te dará un error claro. Los tipos ayudan aquí también. "pyannotate" https://pypi.org/project/pyannotate/. Las anotaciones de tipos te permiten luego compilar Python para ganar rendimiento "sin coste". Las anotaciones se pueden meter en el mismo código o en un fichero "compañero". Usar un fichero "compañero" es útil para poder usar anotaciones modernas en versiones antiguas de Python. Evitar "contaminar" el sistema de control de versiones con cambios masivos irrelevantes que ofuscan la historia de un proyecto. Por ejemplo, el autor original del código. Que los creadores de código y los etiquetadores de tipos sean personas diferentes. "typeshed": Collection of library stubs for Python, with static types: https://github.com/python/typeshed. ¿Y meter tipos en los comentarios, como se hacía antiguamente? Hay mucha literatura de ingeniería de software sobre si es bueno documentar tipos o no, según el tipo de equipo y el tipo de proyecto. [40:17] Python podría ser mucho más rápido aunque no se usen tipos. Podría ser mucho más inteligente. Descubrimiento de tipos en tiempo de ejecución. Tema recurrente. Numba: https://numba.pydata.org/. Javascript V8: https://en.wikipedia.org/wiki/V8_(JavaScript_engine). [43:06] Habiendo tantos compiladores, ¿por qué no se integra alguno en el intérprete normal de Python? Complejidad y compatibilidad. Faltan manos. Hay muchos "gérmenes" que no germinan. Dispersión de esfuerzos. [46:12] Puntos de dolor de Python para la gente que viene de otros lenguajes: Tipos. Velocidad. Espacios significantes. [46:37] ¿Qué es "Python"? Cada novedad de sintaxis de Python cambia el lenguaje. ¿Qué es Python? Problemas para los que llegan nuevos al lenguaje. Hay organizaciones grandes que un lenguaje sin tipos ni siquiera lo consideran. [51:22] Cultura común en todos los proyectos Python. Baja barrera de entrada si conoces esa cultura. La cultura va evolucionando. Solución de compromiso: Meter tipos solo en la frontera. [53:02] El tipado avanzado de Python 3.9 da un error de sintaxis al importar el código en una versión anterior de Python. [54:46] El operador morsa no se puede usar dentro de un "list comprehension": >>> [i for i in ('a', '' ,'b') if i := i.strip()] File "", line 1 [i for i in ('a', '' ,'b') if i := i.strip()] ^ SyntaxError: invalid syntax No queda otra que escribirlo como: >>> [i.strip() for i in ('a', '' ,'b') if i.strip()] ['a', 'b'] duplicando el i.strip(). [56:40] En versiones de Python anteriores a 3.8 no se podría usar un continue en un finally. El texto era https://docs.python.org/3.7/reference/compound_stmts.html#the-try-statement: When a return, break or continue statement is executed in the try suite of a try...finally statement, the finally clause is also executed ‘on the way out.’ A continue statement is illegal in the finally clause. (The reason is a problem with the current implementation — this restriction may be lifted in the future). Eso se solucionó en Issue32489: Allow 'continue' in 'finally' clause: https://bugs.python.org/issue32489. [57:47] f-string con datetime https://docs.python.org/3/library/datetime.html. Ya está en los propios ejemplos de PEP 498: Literal String Interpolation: https://www.python.org/dev/peps/pep-0498/. [59:22] Modo depuración en f-strings en Python 3.8: >>> a = 5 >>> f'{a=}' 'a=5' Útil para el loging. [01:00:47] Versiones fijas de dependencias y actualizar un despliegue. Herramientas para esto: "pip" https://pypi.org/project/pip/, "virtualenv" https://pypi.org/project/virtualenv/. "pipenv" https://pypi.org/project/pipenv/. "Poetry": https://pypi.org/project/poetry/. Grafo de dependencias "pip-tree": https://pypi.org/project/pip-tree/. Paralelismos con el enlazado estático y dinámico. [01:14:22] ¿Por qué se ha instalado este paquete, qué paquetes exige y qué paquetes dependen de él? pip show. Grafo de dependencias "pip-tree": https://pypi.org/project/pip-tree/. [01:19:22] Visualizar el grafo de versiones de un sistema de control de versiones moderno. Por ejemplo con Mercurial: "hg glog" https://www.mercurial-scm.org/. [01:23:07] Recogida de basuras: Design of CPython’s Garbage Collector: https://devguide.python.org/garbage_collector/. Hora de sacar la basura garbage collector - Pablo Galindo y Victor Terrón - PyConES 2018 https://www.youtube.com/watch?v=G9wOSExzs5g. La recolección de basura de la generación más antigua funciona de forma diferente. En vez de ser por un número fijo de desequilibrio entre creación y destrucción de objetos, funciona por porcentaje.

I often bring a garbage bag with me on my Hook Mountain walks. I can’t stand to see trash on the trails, so I feel compelled to do my part to clean up the garbage along the way. I unpack some associations and metaphors that come to mind while collecting garbage. Garbage collectors were important to Martin Luther King, Jr. and the civil rights movement. Garbage collectors have been critical in nationally exposing and highlighting the abuses, non-unionized, low-paying jobs and dangerous working conditions that too many people have suffered under. MLK brought the garbage collectors’ plight into our consciousness, cared about them being treated with dignity and respect. Picking up and clearing garbage, has become a spiritual practice for me. It is a minuscule step in what truly needs to be done to address advocacy for our precious earth, but I feel cleansed, renewed and grateful for this simple measure to clean up garbage, outwardly and inwardly! May you be inspired to clean up your surroundings. May you treat nature with awe, reverence and wonder. May we learn multiple ways to be our planet’s fierce advocate.

Normally I'd start this out with some of the funnier things that happened; but before I dive into what happened last week, I want to talk about this week. Warning: death and violence follow. Yesterday was the 31st anniversary of the École Polytechnique massacre. If you're not familiar with this atrocity, let me quote Deb Chachra's chilling telling of the event:  On December 6, 1989, in late afternoon a man had walked into the École Polytechnique, the engineering school of the University of Montreal, carrying a hunting rifle, ammunition, and a knife. He entered a mechanical engineering class of about sixty students, separated out the nine women, and told them, "I am fighting feminism." One of the women, Nathalie Provost, responded, "Look, we are just women studying engineering, not necessarily feminists ready to march on the streets to shout we are against men, just students intent on leading a normal life." She reports that his response was, "You're women, you're going to be engineers. You're all a bunch of feminists. I hate feminists."He then opened fire on the women, killing six of them. Then he went from floor to floor in the building, targeting and shooting women.Fourteen women were killed that day, twelve of them engineering students, one a nursing student, and one a university employee.Here are their names: Anne St-Arneault, Geneviève Bergeron, Hélène Colgan, Nathalie Crotea, Barbara Daigneault, Anne-Marie Edward, Maud Haviernick, Barbara Klueznick, Maryse Laganière, Maryse Leclair, Anne-Marie Lemay, Sonia Pelletier, Michèle Richard, and Annie Turcotte. (Me: You can hear more about these women here.)An additional thirteen people were injured. Nathalie Provost was shot four times, but survived. In the weeks, months, and years that followed, among other responses, Canada implemented stricter gun-control regulations, and began to observe December 6th as a National Day of Remembrance and Action on Violence Against Women. The event remains the worst mass murder in Canadian history.Our industry has problems with sexism, whether latent or outright. While we hope never to have another atrocity like this one; we should strive for equality and justice in our industry. As a white dude in tech, I'll do everything I can; and I ask you to do the same. If you've never had to fear for your life just because you wanted to be an engineer, then you too need to stand up and help stop the sexism in our industry. Now, on to what happened last week in the world of .NET. 

In this episode, David Delabassee (Developer Relations) discusses with Per Liden (ZGC Lead) the Z Garbage Collector that is now production ready in JDK 15.

Rehan Staton, a 24-year-old college student who previously worked as a garbage collector, was accepted to Harvard Law School. Born and raised in Maryland, Staton had a difficult life growing up. At one point, his father, who was his family's sole provider, worked three jobs at once to make ends meet. Because of the difficulties his family faced, Staton struggled with his academic performance in elementary school. However, he eventually excelled and became one of the top students after getting help from a tutor his father met. When he was in high school, Staton focused on boxing and dreamed of becoming a professional athlete. However, his hopes were dashed because of a shoulder injury. Instead of continuing his studies, he decided to work as a garbage collector after graduating from high school. He said that he wanted to do it to help his father pay for bills and other household expenses. A higher-up from Staton's work heard about his story and helped him enroll at Bowie State University. Two years later, he transferred to the University of Maryland. After graduating in 2018, Staton became an analyst at a consulting firm. He eventually decided to pursue law and was accepted into Harvard Law School. Staton said that he could not have made it without his support system. Having his family and coworkers by his side inspired him to give his all and pursue his dreams. He will attend Harvard Law School this fall. To help with his expenses, a fundraiser has been set up.

“Rust hat alle Vorteile von Go, PHP, C und JavaScript und ist dazu noch typsicherer als alle anderen Sprachen,” sagt Matthias Endler, ein waschechter Rustacean, den wir in Folge 49 zu Gast haben!Rust ist eine Programmiersprache, die vor allem auf Performance und Sicherheit ausgelegt ist. Während sie systemnah ist und leistungsstarke Abstraktionen bietet, die stark an dynamische Sprachen wie Ruby oder Python erinnern, hat sie außerdem eine Speichersicherheit ohne Garbage Collector auf Lager! So macht sie die Low-Level-Programmierung einfacher und sicherer.In Folge 49 plaudern wir mit Matthias Endler über die Vorzüge der Programmiersprache. Er erzählt, dass der Code tatsächlich lauffähig sei, wenn der Compiler das sagt, und dass in Rust geschriebene Services monatelang problemfrei laufen können! Diese Vorteile hören wir uns genauer an und sprechen dabei auch über Plug-ins, die man mit Rust in anderen Sprachen einbinden kann, grundsätzliche Konzepte wie Borrowing und Ownership, und wie Rust auf CDN Edges mit WebAssembly ausgeführt werden kann.Pssst! Wir haben gehört, dass die Programmiersprache sogar von SpaceX verwendet wird… Na, wenn das mal nicht ein Reinhören wert ist! ;)Wenn ihr Lust habt, Matthias zu treffen und beim Thema Rust auf dem Laufenden zu bleiben, besucht doch das nächste Meetup von Rust Cologne in Köln!

O Garbage Collector é um importante componente que a maioria dos runtimes modernos possuem e como eles funcionam no background e funcionam bem, cada vez menos as pessoas sabem da sua existencia ou se preocupam em enteder a sua utilidade. Um arquiteto se soluções precisa entender como as coisas funcionam para dar boas soluções e por isso este componente faz toda a diferença.

1. First, let's make sure you don't have an agreement with someone that they bring home all their homework for you to do...cause that ain't cool.  You're not broken or busted, you have an unhealthy agreement with someone who lacks self-responsibility. 2. People that sincerely come to you with their heartache, know you are a safe space, and often don't need much more than a listening ear.  Make sure you remind yourself there's nothing else to be done, but love em.  That's more than enough. rebeccagarifo.com with love and joy- Rebecca Garifo Ph.D.

Panel: Charles Max Wood Guest: Nell Shamrell-Harrington This week on My Ruby Story, Chuck talks with Nell who is a principle engineer at Chef. Check them out at Chef.Io. She also works with Operation Code. This organization helps veterans to learn code, and helps them get a technical job. Check out today’s episode where Chuck and Nell discuss Ruby, Rust, and much more! In particular, we dive pretty deep on: 2:00 – Chuck: Episode 105 is another episode you’ve been on before. 2:25 – Chuck: I want to spotlight you and talk about what you are working on. How did you get into programming? 2:38 – Nell: I was a theater major in college. I graduated in 2007 and the big financial crisis hit in 2008. I found work at the Physics Department in Seattle. Once they found out that I knew how to code, they gave me more coding to do. When you are doing just the mathematics portion – you don’t see how this applies to real life. I didn’t pursue it because I didn’t see how it worked in the real world. Then I saw eventually how my theater background really helped me with coding because you have to be super creative. After that (this is when I got into Ruby) my roommate in college sent me a message. She was working with Ruby, too, and she wanted to bring me on as a junior developer. 5:55 – Chuck: It’s interesting, too, to see what you just said. Not seeing the real-world application with some of that stuff. I can relate to that. I wanted to get into IT after college. The other thing is that it was someone you KNEW to get you into Ruby. People get into a specific framework because of someone that they knew/know. 6:54 – Nell: Yes, it’s the personal testimonies that help people make those decisions. 7:13 – Chuck: It was someone that you KNEW that helped you get X job. 7:24 – Nell: Yes, in Operation Code, too. Take a look at this candidate (normally you wouldn’t look at them b/c of their CV) and take a chance on them. 8:09 – Chuck: One thing that I am curious about what’s been your favorite thing to work on with Ruby? 8:38 – Nell: I worked on the supermarket product. Cookbook is a chef recipe for infrastructure... We weren’t just running a site that people were using. They were saying: we love it, but we are behind a firewall. They couldn’t use the public one and they wanted a private one. The answer was: Yes! That was the first time I worked on software – packaged and distributed. I loved the breadth of the industries that it had an affect on. It was cool to see different industries use my work through a Ruby on Rails application. Ruby does scale! 10:42 – Chuck: Let’s talk about your work at Chef. You worked on Supermarket and then what was the distributed part to it? 11:05 – Nell: Chef Omnibus was the tool we used. You could take that package and install it on the infrastructure... 11:33 – Chuck: I worked at a university for a while. The work I did was that the access to the Internet was limited. Chef would have been nice! 11:58 – Chuck: What did you do at Blue Box? 11:59 – Nell: Software engineer there and we were a hosting company. We had a Rails application... I helped write the code. 12:29 – Chuck: What are you working on now? 12:32 – Nell: I am working on a project called Habitat. Nell talks about what THIS project is and how it functions. Check it out! 14:20 – Chuck: How did you get into Operation Code? 14:26 – Nell: Both my parents were air force operators. I wanted to but I had a physical limitation so I couldn’t. I grew up in military culture from 0-14 years old. After that I realized in my 20’s I really missed it. After the military it’s scary because you don’t have (maybe) a sense of purpose like you did in the military. She asked how she could help and someone referred her to Operation Code. She realized she could be an asset and help these veterans. She works with close to 3,000 veterans to help them give a purpose after military life. They learn code and then hopefully find a technical job. 17:13 – Chuck: I spent some years around that life, too, when I was a missionary overseas. My brother-in-law was medically discharged. You see this change and it can be scary for them. You wind up in this position and you want to help. I admire this. These folks have sacrificed for us so let’s make a difference for them, too. 18:35 – Nell: My friend said that she didn’t like it when people thanked her for her service. She said that so many warzones it seems empty. When she heard this it was powerful to her. 19:40 – Chuck: How can people get involved? 19:43 – Nell: Operation Code – Hit the JOIN link. You can sign-up to be a volunteer. The slack community is where all the magic happens.  20:24 – Chuck: Anything else? 20:28 – Nell: Habitat is written in Rust. I haven’t done tons in Ruby right now. But what I am known in Ruby is for regular expressions. People have told me that it has helped them a lot. 22:14 – Nell: Regular expressions can be a lot of fun but they are mind numbing at first. Seeing an example can help. 22:33 – Chuck: Habitat is written in Rust. What’s that transition like from Ruby to Rust? 22:49 – Nell: I took a Latin course. Learning Rust was like learning Latin in that it’s a HUGE learning curve. However, in both that I stopped fighting with the language. And stepped back to see why it was doing what it’s doing. In Rust there is no Garbage Collector. My Ruby experience did give me a leg-up. Nell continues to talk about the differences between Rust and Ruby. 24:30 – Chuck: Which language do you like better? 24:34 – Nell: Personally, Ruby but for this project Rust! 24:45 – Chuck: We were talking about the tradeoffs between... 25:01 – Nell: Yes, choose the language that works for THAT project and for your team. 25:17 – Chuck: How can people find you? 25:23 – Nell: Twitter. I check it throughout the day, so feel free to DM me. GitHub, too. I have gotten back to voice acting so check that out! 26:11 – Advertisement – Fresh Books!

You see this change and it can be scary for them. You wind up in this position and you want to help. I admire this. These folks have sacrificed for us so let’s make a difference for them, too. 18:35 – Nell: My friend said that she didn’t like it when people thanked her for her service. She said that so many warzones it seems empty. When she heard this it was powerful to her. 19:40 – Chuck: How can people get involved? 19:43 – Nell: Operation Code – Hit the JOIN link. You can sign-up to be a volunteer. The slack community is where all the magic happens.  20:24 – Chuck: Anything else? 20:28 – Nell: Habitat is written in Rust. I haven’t done tons in Ruby right now. But what I am known in Ruby is for regular expressions. People have told me that it has helped them a lot. 22:14 – Nell: Regular expressions can be a lot of fun but they are mind numbing at first. Seeing an example can help. 22:33 – Chuck: Habitat is written in Rust. What’s that transition like from Ruby to Rust? 22:49 – Nell: I took a Latin course. Learning Rust was like learning Latin in that it’s a HUGE learning curve. However, in both that I stopped fighting with the language. And stepped back to see why it was doing what it’s doing. In Rust there is no Garbage Collector. My Ruby experience did give me a leg-up. Nell continues to talk about the differences between Rust and Ruby. 24:30 – Chuck: Which language do you like better? 24:34 – Nell: Personally, Ruby but for this project Rust! 24:45 – Chuck: We were talking about the tradeoffs between... 25:01 – Nell: Yes, choose the language that works for THAT project and for your team. 25:17 – Chuck: How can people find you? 25:23 – Nell: Twitter. I check it throughout the day, so feel free to DM me. GitHub, too. I have gotten back to voice acting so check that out! 26:11 – Advertisement – Fresh Books!

Panel: Charles Max Wood Guest: Nell Shamrell-Harrington This week on My Ruby Story, Chuck talks with Nell who is a principle engineer at Chef. Check them out at Chef.Io. She also works with Operation Code. This organization helps veterans to learn code, and helps them get a technical job. Check out today’s episode where Chuck and Nell discuss Ruby, Rust, and much more! In particular, we dive pretty deep on: 2:00 – Chuck: Episode 105 is another episode you’ve been on before. 2:25 – Chuck: I want to spotlight you and talk about what you are working on. How did you get into programming? 2:38 – Nell: I was a theater major in college. I graduated in 2007 and the big financial crisis hit in 2008. I found work at the Physics Department in Seattle. Once they found out that I knew how to code, they gave me more coding to do. When you are doing just the mathematics portion – you don’t see how this applies to real life. I didn’t pursue it because I didn’t see how it worked in the real world. Then I saw eventually how my theater background really helped me with coding because you have to be super creative. After that (this is when I got into Ruby) my roommate in college sent me a message. She was working with Ruby, too, and she wanted to bring me on as a junior developer. 5:55 – Chuck: It’s interesting, too, to see what you just said. Not seeing the real-world application with some of that stuff. I can relate to that. I wanted to get into IT after college. The other thing is that it was someone you KNEW to get you into Ruby. People get into a specific framework because of someone that they knew/know. 6:54 – Nell: Yes, it’s the personal testimonies that help people make those decisions. 7:13 – Chuck: It was someone that you KNEW that helped you get X job. 7:24 – Nell: Yes, in Operation Code, too. Take a look at this candidate (normally you wouldn’t look at them b/c of their CV) and take a chance on them. 8:09 – Chuck: One thing that I am curious about what’s been your favorite thing to work on with Ruby? 8:38 – Nell: I worked on the supermarket product. Cookbook is a chef recipe for infrastructure... We weren’t just running a site that people were using. They were saying: we love it, but we are behind a firewall. They couldn’t use the public one and they wanted a private one. The answer was: Yes! That was the first time I worked on software – packaged and distributed. I loved the breadth of the industries that it had an affect on. It was cool to see different industries use my work through a Ruby on Rails application. Ruby does scale! 10:42 – Chuck: Let’s talk about your work at Chef. You worked on Supermarket and then what was the distributed part to it? 11:05 – Nell: Chef Omnibus was the tool we used. You could take that package and install it on the infrastructure... 11:33 – Chuck: I worked at a university for a while. The work I did was that the access to the Internet was limited. Chef would have been nice! 11:58 – Chuck: What did you do at Blue Box? 11:59 – Nell: Software engineer there and we were a hosting company. We had a Rails application... I helped write the code. 12:29 – Chuck: What are you working on now? 12:32 – Nell: I am working on a project called Habitat. Nell talks about what THIS project is and how it functions. Check it out! 14:20 – Chuck: How did you get into Operation Code? 14:26 – Nell: Both my parents were air force operators. I wanted to but I had a physical limitation so I couldn’t. I grew up in military culture from 0-14 years old. After that I realized in my 20’s I really missed it. After the military it’s scary because you don’t have (maybe) a sense of purpose like you did in the military. She asked how she could help and someone referred her to Operation Code. She realized she could be an asset and help these veterans. She works with close to 3,000 veterans to help them give a purpose after military life. They learn code and then hopefully find a technical job. 17:13 – Chuck: I spent some years around that life, too, when I was a missionary overseas. My brother-in-law was medically discharged.

Microsoft is doing a good job in shielding the complexity of what is going on in the CLR from us. Until now Microsoft is taking care to optimize the Garbage Collector and tries to come up with good defaults when it comes to thread and connection pool sizes. The problem though is that even the best optimizations from Microsoft are not good enough if your application suffers from poor architectural decisions or simply bad coding.Listen to this podcast to learn about the top problems you may suffer in your .NET Application. We have many examples and we discuss how you can do a quick sanity check on your own code to detect bad database access patterns, memory leaks, thread contentions or simply bad code that results in high CPU, synchronization or even crashes!

Rebecca and guest co-host Emily Pearl Goodstein talk with Watt Hamlett (a man of many talents) about nicknames (wanted and unwanted), things that we judge (or don't judge), personal style (or lack thereof), how it seems like we all have mentors (and/or mentees), whether ladies should be required to shave their legs (or not), and whether one should admit to ever having told a lie (or lie and claim to have always told the truth).
