Elixir enthusiast. I love playing and watching basketball, reading books, and traveling.
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.

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.

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.

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!

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.

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!

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.
