@philipbrown @TylerAYoung @Code_of_Kai That‘s how libraries like Nx are able to unimport Kernel functions to replace them with their own :)

@TylerAYoung @Code_of_Kai I had no idea this works 🤯

#ElixirLang folks, is there a way to un-import a function? I have a third-party module that imports itself in its (required) `use`, but I'd like to replace one of the functions it imports.

MY GAME STUDIO IS HIRING! We secured additional funding for our multiplayer PC strategy game and have openings for Lead Character Artist, Senior Animator, Senior Tools Engineer, and Senior AI Engineer (not ML/GenAI). Please retweet, ping friends, & tell all!!

Just merged our first PhoenixTest.Playwright test into main. Feels good! We get the wonderful PhoenixTest syntax (🙌 @germsvel) , but with the ability to execute JavaScript, all without the unreliability of Chromedriver. 😌 Shoutout to @aeftes for making this happen!

@_wilfredh Yeah, I‘d love if that would be the case for more specs. A language agnostic set of test cases makes it so much easier to build implementations for something. Tests can guide the implementation way before the implementer has a thorough understanding of the spec

I love how the CommonMark Spec has a test suite that's just a JSON array. It's really easy to test a library for compliance, and I've seen developers nerd-sniped into full compliance. spec.commonmark.org/0.31.2/spec.js…

Elixir v1.18 is out: elixir-lang.org/blog/2024/12/1… 🎄🍾 It is a fantastic release: type checking of function calls, Language Server listeners, built-in JSON, ExUnit improvements, IEx auto-reload, and more. See the announcement for examples and videos.

@davydog187 @tvlabs Oh congrats. I really enjoy developer voices as well :)

It was an honor and privilege to share the story of @tvlabs with Kris, especially given that Developer Voices is one of my favorite podcasts I hope you enjoy youtu.be/_MwXbHADT-A

@shahryar_tbiz youtu.be/YJp6r6IXP6U?si… that one‘s been out for a while 😅

@lostkobrakai I always wanted to know what you look like. 😂😂😂

Today I published a first time video of mine talking about a concept I called "Behaviour Stacking" while working on it. kobrakai.de/videos/rwd3e If you ever wondered libraries like phoenix or bandit build features on top of OTP primitives work this is for you.

kino_websocket, a small #elixirlang library for @livebookdev with a smart cell containing in interactive websocket client ... #myelixirstatus Yes, I'm not a frontend guy, my JS skills suck 🙄

@thibaut_barrere @YOOOODAAAA @philipbrown @z_4seven That‘s the way. Fetching erlang and elixir in like 10 to 15secs.

How are you managing multiple versions of Elixir + Erlang on macOS? I feel like there has to be better way than asdf.

@jskalc @elixirphoenix And that problem exists all throughout the stack. You could be configuring kernel or stdlib, which are the first apps to start on the beam, not just things in your app being developed.

@jskalc @elixirphoenix Because it‘s simpler than expecting your app to be able to hot code reload all stateful processes, which might depend on the config changes. It‘s quite likely for apps to not support that. Like changing the port of your endpoint won‘t apply unless its process is restarted.

Am I the only one wondering why it's necessary to restart a server after making configuration changes in @elixirphoenix? 😅 #myelixirstatus

@arvindpunk @josevalim @thecodingtrain I was about to suggest those as well.

@josevalim I genuinely feel programming paired with realtime visual feedback is the way to go for beginners. @thecodingtrain's exceptional videos on p5.js are externally easy (and fun) to follow.

Any online courses/materials for a 10 year old who really wants to learn how to program? Either in english, polish, or portuguese? He already did a Scratch course and we are doing Lego SPIKE together on weekends. Maybe it is time for actually writing code? Suggestions?

@accomazzo @reachfh @sequinstream @elixirlang There‘s also #unboxed_run/2" target="_blank" rel="nofollow noopener">hexdocs.pm/ecto_sql/Ecto.… for smaller amounts of unboxed tests.

We have a lot of Postgres tests at @sequinstream. Because we're testing things like the replication slot, we can't use @elixirlang Ecto sandboxes all the time. We need rows to commit and flow through the slot. We discovered a cool pattern for this in the Oban project – h/t @sorentwo! Why can't we use Ecto sandboxes? Ecto sandboxes wrap all your operations in a transaction. So, changes are not visible outside that transaction. Importantly for us, this means that changes are also not sent to the replication slot – the transaction has to commit first. Setup You can create a new repo just for test, `UnboxedRepo`. Ours lives in `test/support`. The UnboxedRepo, of course, doesn't use an Ecto sandbox in test. So you need to make sure that you clear unboxed tables before each test run. Start it in `test_helper.exs`: `Sequin.Test.UnboxedRepo.start_link()` Then you can purge tables in your `DataCase` `setup` block like so: ``` if tags[:unboxed] do Enum.each([Schema1, Schema2, Schema3], &UnboxedRepo.delete_all/1) end ``` Naturally, with this approach, you need to run unboxed tests with `async: false` and the `:unboxed` tag (more on future work here below). Schemas and factories Because we have a lot of tests that are inserting/updating/deleting rows, we have test tables that we use for this purpose. These tables belong to the `UnboxedRepo`'s migrations, so we only create them when `MIX_ENV=test`. We have tables to test different permutations that are possible in Postgres, for example a table without primary keys or a table with >1 PK. We also have full-blown Ecto schemas for each of these tables, which also live in `test/support`. And factories to complement them, so we can easily arrange tests. We can setup a situation with a database that has a table with no PKs and a few rows with a single line. Future work Most of our tests are async, and so we can run 528 tests in 5 seconds. It's fine for now that we have some `sync` tests, seems to barely make a difference. However, we have a couple of other clever ideas to provide ourselves a sandbox outside of Ecto's transactional sandbox model: 1. We could add a column to our test tables, like `test_pid`. Our tables are explicitly designed for test anyway. Then, we could ensure all writes include the `test_pid` and all reads include a filter for the `test_pid` (could use Process dictionary here). 2. We could use Postgres partitions to do isolation. Each test would then simply work inside its own partition. As always, you can check out the code in our repo: github.com/sequinstream/s… Just do a global search for `UnboxedRepo` to see all the pieces. Our test tables contain Dune characters, so you can search for eg `Character` to see an example of a table + schema + factory.

Quick LiveView tip that I used the other day: add "contents" class (display: contents) to the LiveView container - this way the "box" property goes directly to child elements #MyElixirStatus

There’s an app called ‘Paprika’. Download it. It costs a couple dollars but it’s worth it. Any time you find a recipe you like, you copy the URL, paste it into Paprika, and it will download the ingredients and directions and save it as a simple recipe card. You can curate an entire library of recipes and never have to wade through a web page again. You can scale the recipe to halve/double/etc it, you can change the units (metric/imperial), and you can check off ingredients as you use them so you know where you’re up too. It’ll change your life.

@lawik Things are not as packed on my end, but certainly feeling similar atm xD

Yes I deferred everything until after Code BEAM but why did all of it go on tuesday? 2-3 hours intense pairing (not originally planned) Podcast recording Hong Kong meetup presentation And in 90 min another podcast. I'm a dumbass. I will have no brain this evening.

meetup.com/elixir-munich/… I won't be able to join due to travel, but if you're in the area feel free to join.

.@lawik is bringing us the latest and greatest in Nerves with additional practical demos and some international participation! 🙌 #CodeBEAM #CodeBEAMEurope #webeamtogether

So... my contract gigs will end in a few days. I’m now looking for a job! 🤓 - Principal engineer, backend/systems/arch focus - Fully remote, flexible hours (hard to find ppl in the same tz), pref async work - @elixirlang is def my strength, but I just love doing stuff
