The importance of tests goes beyond your own code. Last week I upgraded all mix deps and when I ran my tests, I found that some auth UIs broke. I later found that AshAuthentication introduced a bug to the magic link flow. Fortunately my tests caught that and I didn’t push the bug live. #ElixirLang

Another day, another time I had to search hexdocs for how to use Enum.reduce/3. For some reason I can’t memorize the params order for this function 😅 #ElixirLang

OK, I’ve tried both Fly.io and Gigalixir. Between the two, I think Fly.io is a bit better because it’s easier to use. But man… they made it really hard to use what they call “unmanaged” Postgres. It’s really annoying! They’re trying to force everyone into paying for managed Postgres. #ElixirLang

@gigalixir.com Just wanted to let you know that I tried to sign up and got this error. I’m _not_ using VPN. It looks like your system thinks that Starlink is a VPN.

Hey #ElixirLang friends! Can I get some recommendations on good hosting providers for Elixir / @ash-hq.org applications? I’m currently using Fly.io during the dev phase, but I’d like to explore other options for production. Note: I’m not experienced in DevOps, so I’d prefer managed hosting.

🚨Another supply chain attack on npm. This one affects 40+ packages. Beware!!! www.aikido.dev/blog/s1ngula... thehackernews.com/2025/09/40-n...

Maybe most of #ElixirLang folks won’t care, but for those of you using npm in your projects, please pay attention to this 0-day attack! www.aikido.dev/blog/npm-deb... Tons of npm packages compromised. Make sure to check your apps and local envs too, especially if you do anything crypto-related.

Made a small contribution to the OS community. This time to Expert, the official lang server for #ElixirLang. As I was following the installation guide, I noticed a dependency that was not mentioned in the prerequisites. I opened an issue and after some discussion, opened a PR that was just merged.

For those interested, PragProg.com sent a coupon code that gives 35% off almost all their books! I used it to finally purchase the @ash-hq.org book by @zachdaniel.dev and @sevensea.cat 🤩 #ElixirLang

TIL this mix command to run only the test that failed a prior run. Feeling dumb for not knowing this before. #ElixirLang

💫Just released: a GitHub Action to submit Elixir/Mix dependencies via GitHub's Dependency Submission API. ✅ Perfect for unlocking security alerts, dependency graphs, and Dependabot Security updates! Check it out: github.com/erlef/mix-de... #Elixirlang

I’m building a function to parse a CSV and insert records in the DB, giving back a CSV indicating which rows were successfully processed vs not. The @ash-hq.org has a few different error modules, so this is what I’m trying to do to parse the most common errors. Is there a better way? #ElixirLang

Expanding a little bit on my previous tip for speeding up tests: the config you’ll need to use depends on which hashing library you’re using in your project. Add one of these to your `config/test.exs` based on the hex pkg you have in your mix.exs. #ElixirLang

If you’re using Ash Authentication, don’t forget to add this to your `config/test.exs`. I went from running 133 tests in 33.3 seconds to just 0.9s! #ElixirLang

ObanWeb becoming free is the best news of this year so far. #ElixirLang

Just made my first contribution to an open source project ever. It was just a one-liner to fix a code example, but I feel happy to finally start contributing! At the same time, I feel ashamed of not doing this earlier. It’s better to do it now than never, I guess. 😅

Half an hour. That’s all the time I needed to develop a GraphQL CRUD for a resource with authorization policies in place, as well as version history and soft deletes. @ash-hq.org is THE framework! #ElixirLang

Although @ash-hq.org is really cool, I’m still not sure if I like the similarities with Rails. Ash does a lot for you, but it comes with a lot of implicit things from macros. At least the foundation is still a functional, immutable language. #ElixirLang

I’d love to hear you guys’ opinion on the fact that Elixir does not have `while`. Today I had to do an indefinite-range loop that would perfectly fit with a while, but I had to use recursion instead. I really like the recursive solution, but I wonder why we don’t have `while` available. #ElixirLang

I just configured ErrorTracker (hex.pm/packages/err...) on my project that uses @ash-hq.org and found it’s super easy to restrict the error dashboard to logged in users. If you use Ash Authentication and its Phoenix extension, you only need to pass the `on_mount` option. It just works! #ElixirLang

git-wrapped.com/profiles/fla... The only weird thing is the top language being HTML. I’m pretty sure I coded in #ElixirLang the most this year.

Hey #ElixirLang folks! How do you build your GitHub yaml file for running tests and deploying to fly.io? My pipelines are super slow right now — taking around 14 min. I think it’s because I’m installing asdf and then installing Elixir and Erlang, which takes almost 10 min. Need to optimize that 😢

I really hate when I see job opportunities that don’t inform the compensation, or at least a comp range. You see job descriptions that go deep in details of what they want from you, but are super secret when it comes to tell you how much you’ll be paid. Just be clear and tell at least a range.

Note to self: when using Ash Authentication, if I need to replace the framework’s logo by my own, make sure I override both the light and dark mode images. I’d say @ash-hq.org’s documentation could be a bit clearer on that, maybe even with a tip. I’d even open a PR to update the docs. #ElixirLang

Not only the Ash Framework is awesome, the community is also great! People are always willing to help on the Discord community. If you’re into Elixir, you should definitely give it a try. #ElixirLang

#ElixirLang is what I talk the most about on Bluesky. Not surprised at all.

Funny quote I saw in a blog article I was reading today: “Also I would like to thank ChatGPT and Gemini for outputting garbage and hallucinating solutions wasting hours of valuable time that were only recovered by the help of the author and the Elixir community.” #ElixirLang

Anyone else having issues with custom handles on Bluesky? I added my domain yesterday (using the file upload to server) but it keeps saying my handle is invalid 😢

I think it’s 042. What do you think?

Sometimes I feel like I’ve been spoiled by #ElixirLang. I’m used to building things so fast with it that when things take a little more time, I feel a bit frustrated.

“If your code is worth writing, it’s worth testing.” Another nice quote from the Programming Phoenix 1.4 book.

Yes!! Phoenix LiveView 1.0 is out! phoenixframework.org/blog/phoenix... Now I also hope that @redrapids.bsky.social can finish his book on it soon too! 🤞🏽🙏🏽 pragprog.com/titles/livev... #ElixirLang

Tip: be careful if you’re adding the Ash Authentication to an existing project that already has a `users` table. You may find some conflicts when running the migrations. In my case, it was easier to remove my own table in favor of the one added by Ash, then re-add my custom columns. #ElixirLang

it's the only way

We are hiring a full stack dev. in Europe. Preferably with #elixirlang experience, but we can also teach you! You will be working with an amazing team, with the latest tech, building an AI native application. Job will go public in a couple of days, but shoot me a message if you are interested!

It's so fun that people out there are playing the "full stack" role without knowing what #liveview is and how easier would be to adopt it #elixir #phoenix

Anyone else having issues with loading some feeds on #bluesky?

I’m so happy today! I convinced my business partners to build our new project in #ElixirLang using the @ash-hq.org. Let’s goooooo!!!

Looking for my next job! - Based in Berlin 🇩🇪, but also open to remote. - I've been most excited about #ElixirLang lately, but also open to other tech stacks(I've worked with Clojure, Rust, JS/TS) Some stuff I've worked on recently below👇. (And I'd appreciate a repost :))

TIL that IEx allows us to fetch a previous value by using `v(n)`, where `n` is the number of the expr. It also accepts negative numbers to fetch the latest nth expr. Example: ``` Repo.get_by(Post, name: “Foo”) %Post{} post = v(-1) ``` Now `post` has the value return by `Repo.get_by` #ElixirLang

Nice quote from the Programming Phoenix book: “The work best suited to the database must be done in the database.”

Coming soon, LVN Go for Apple Vision Pro and Apple TV! #ElixirLang

#ElixirLang is the first programming language that made me have fun writing tests. Call me crazy, but I actually have fun writing tests in Elixir.
