Episode 165 feat. José Valim
# Episode 165 - José Valim on Bytepack, Open Source, and LiveView changes in Phoenix 1.5 Chris and Desmond are backed by a very special guest; José Valim! You might know José as the creator of the Elixir programming language and we're excited to have him back as a 3rd time guest on the show. José walks us through a brand new Dashbit project, Bytepack which is a way to package and sell software projects and takes all of the hassle out of the process today. We dig into Bytepack and discuss sustainable open source, Dashbit, and more. As well as that we also hear about the new Phoenix 1.5 features, LiveDashboard, all of the great new LiveView enhancements, some nice new Elixir additions and much more!

Episode 160-A new decade, Plataformatec acquisition, Elixir 1.10-rc and more
We’re back! It’s been a while but it’s 2020 and Chris and Desmond are back with a new episode for the new decade. In this very timely episode we dive into the big community news; Plataformatec being acquired and what that means for the community and the new Elixir v1.10-rc.0 release. After that, we accidentally stray once again into a spirited discussion about ops, Kubernetes, and picking technology that suits you right now. Desmond provides some controversial opinions and we kick off the new year with a bang :boom: ## Links in the show notes - EMPEX LA: https://empex.co/la - Bruce on Twitter: https://twitter.com/redrapids - James & Bruces book: https://pragprog.com/book/jgotp/designing-elixir-systems-with-otp - EMPEX NYC: https://empex.co/nyc - Plataformatec Announcement: http://blog.plataformatec.com.br/2020/01/important-information-about-our-elixir-and-ruby-open-source-projects/ - More context on the announcement on Elixir Forum: https://elixirforum.com/t/plataformatec-acqui-hired-by-nubank/28072/3 - Elixir v1.10.0-rc.0: https://github.com/elixir-lang/elixir/releases/tag/v1.10.0-rc.0 - Elixir 1.9 releases vs Distillery: https://elixirforum.com/t/elixir-1-9-release-vs-distillery/23454 - Jose on Elixir releases vs Distillery: https://news.ycombinator.com/item?id=20267585

Episode 159 - Property-Based Testing & Authorization in APIs
Chris and Desmond are back! In this episode we talk about Desmond’s exploration into Property-Based testing, and then do a deep dive into authorization and access control in Chris’ GraphQL API. Property-based testing is a new world for both of us, but we do our best to tell you all about what libraries to use and how we’re thinking of using it. Chris is deep in some reworking of the authorization code in his GraphQL API and we go into depth talking about how it is structured, some of the challenges of building a flexible authorization system and then how this integrates back into a system. After talking about authorization we then go into validation of parameters in our APIs and how we think about typing and validating them at the boundaries, and in our Ecto Schemas. ## Links * EMPEX LA (https://empex.co/la) * StreamData Library for property testing (https://github.com/whatyouhide/stream_data) * PropEr (https://github.com/proper-testing/proper) * PropSchema (https://github.com/podium/prop_schema) * Property-Based Testing with PropEr (https://pragprog.com/book/fhproper/property-based-testing-with-proper-erlang-and-elixir) * StreamData: Property-based testing and data generation for Elixir (https://elixir-lang.org/blog/2017/10/31/stream-data-property-based-testing-and-data-generation-for-elixir/) * Canada Library (https://github.com/jarednorman/canada) * GraphQL Scalar Types in Absinthe (https://hexdocs.pm/absinthe/custom-scalars.html) * JSON Schema in Elixir (https://github.com/jonasschmidt/ex_json_schema) * API versioning at Stripe (https://stripe.com/blog/api-versioning)

Episode 158 - Oban, Background Jobs, Concurrency, and Is Elixir Even Worth It?
# Episode 158 - Oban, Background Jobs and Designing Resilient Systems in Elixir. In this episode of ElixirTalk Chris & Desmond dive into background jobs using Oban, a new library that relies on Postgres to add persistence to job scheduling. We discuss why you’d want to reach for a library like Oban in the first place, which leads us to a discussion on distributed systems design, failure handling, and some of the gotchas of modeling everything in-memory. We’ve added some extra reading in the links belong for some articles that we didn’t mention in the episode, but might serve as good reading material regardless. ## Links - EMPEX LA: https://empex.co/la - Pigeon Push Notification: https://github.com/codedge-llc/pigeon - Oban: https://github.com/sorentwo/oban - Oban Recipes: https://sorentwo.com/2019/07/18/oban-recipes-part-1-unique-jobs.html - Eli Kim Leveraging GenStage to Implement You Own Event Bus: https://www.youtube.com/watch?v=ffhCUKI2_ho - Dangers of Single Global Process: https://keathley.io/blog/sgp.html - To spawn or not to spawn: https://www.theerlangelist.com/article/spawn_or_not

Episode 153 feat. Dave Lucia- The Dream Stack with Rust & Elixir
Episode 153 – The Dream stack with Rust & Elixir feat. Dave Lucia We kick things off by hearing about the newly launched Elixir Training :tada: which y’all should check out if you’re looking to learn the language, or have friends who might. In todays episode we’re joined by Dave Lucia, VP of Engineering at SimpleBet where we hear about the use of the “Dream Stack” (you heard it here first folks!), which is Elixir using Rust NIFs for performance reasons (in their case calculating real-time betting odds). We spend a lot of time in the episode digging into what NIFs are, why Rust is a good fit for writing Elixir NIFs and what the pitfalls are. We get real technical with dirty schedulers, resource arcs in Rust, and all of the reasons for why you should and probably should not use NIFs unless you really need it. Also in an Elixir Talk first Dave turns around and asks us a question at the end. And in maybe a podcast first we place an on-air bet on who can donate the most to the…

Episode 152 - Hire an Elixir Developer! and Chris's Ecto Adventures
# Episode 152 - The joys of Ecto This week it’s a Chris & Desmond episode! We kick things off by hearing all about Desmond’s latest project – Hire an Elixir Developer – a job board to help companies attract Elixir talent that’s launching soon. We dig into how Desmond has been writing his latest project, hear a bit about how he’s using LiveView and how he’s chasing boring technology to get this project done (Phoenix & Elixir). Chris has also been writing lots of code this week (and has kept Elixirin’) – he talks a bit about how Elixir has mostly just been getting out of his way. We then dig into one of our favorite subjects ... Ecto! We describe the joy of named binds, how we split up Ecto queries, and think about composing queries. We then go onto talk about lateral joins and the limits of Ecto preloads. ## Links * Hire an Elixir Developer – https://www.hireanelixirdeveloper.com/ * Absinthe GraphQL – http://absinthe-graphql.org * Ecto Named Binds – https://hexdo…

Episode 151 feat. Dave Thomas and Brian Mitchell - The Future of Elixir
# Episode 151 – Dave Thomas & Brian Mitchell In this special episode of ElixirTalk we are joined by Dave Thomas and Brian Mitchell where we continue a discussion that we had at EMPEX NYC this year as a fishbowl style format. If you haven’t yet seen the talk, you can do so here: https://youtu.be/pcbNT1iKebc –– probably best if you watch before listening, but you can also listen to this as a standalone episode. This episode is long, but is packed with some great tidbits about Elixir and Erlang and we go into considerable depth about how applications work today as well as outlining a vision for the future. ## Key moments in the episode - Dave lays out some of the key tenants of his argument about augmenting OTP to work better for a world that we’re in today - Brian describes what OTP is and gives his thoughts on Dave’s initial thesis, questioning some of the static nature that Dave argues about OTP - Dave lays out that what we’re doing in Elixir and Phoenix land is the OTP w…

Episode 150 feat. Juan Facorro - Clojerl!
Episode 150 - Clojerl with Juan Facorro This week on the show we’re joined by Juan Facorro, an avid Erlang-er and creator of Clojerl, a Clojure port written in Erlang. We give you an update about Elixir Training, and tell you a bit more about a potential bar / meetup we at EMPEX will be hosting during ElixirConf this year in Denver (if we can find a bar). We then get Juan to give us a run through of Clojerl, diving into the project, his motivations for creating it and going in-depth to some of the challenges Juan had along the way. We understand why you’d even want Clojure on the BEAM in the first place and where the Erlang concurrency model is advantageous here.

Episode 149 - It's just Chris and Desmond. And Elixir Training!
This week we don’t have a guest, so it’s just Chris & Desmond. We kick things off discussing our opening music and how weird it is listening to yourself on a podcast. Desmond tells us about his exploration into webflow and his love (hate) for CSS. We dig into bits in the language that still trip us up, even now with our experience in the language. We dig into some Ecto: query syntax that trips us up, materialized views, application logic vs database logic and lots of other database goodies. Desmond tells us how Phoenix contexts trip him up and we go into some depth about how both of us structure contexts and code in our Phoenix applications. We tell you about ElixirTraining, which is our new venture to help teach more engineers the beauty of Elixir, as well as engineering leaders about why Elixir is a great fit for your organization. Oh, and sorry we said we’d answer some community questions and then never did. Links: - Webflow: https://webflow.io - Database tables explai…

We announce a special new announcement: the launch of Elixir Training, our new business where we’re going out and looking to train more folks on Elixir across the US. We also have a special guest on the show this week: Maxim Federov a Software Engineer at WhatsApp. We dive into some of the joys of using Erlang at bonkers scale (~1.5 billion+ users), using 10k servers and attempt to ask some moderately interesting questions, that Maxim answers like a champ.
