I am back to sponsoring @lpil.uk at $20 / month for his amazing work on @gleam.run

If you didn't catch it, Gleam was ranked as the #2 most desired programming language from the Stack Overflow survey.

Louis's vision, determination, and cultivation of an impressive core team is incredible.

Just set up a @tailscale.com App Connector on @fly.io to securely route to internal services without exposing them to the public internet.

It was a bit tricky to get setup - thinking about writing up the process. Would anyone be interested in a blog post?

In #Phoenix #LiveView v1.1.0-rc.0 we shipped `:key` support for comprehensions in HEEx. The idea was to finally be able to have change tracking in comprehensions. We did this by leveraging LiveComponents. Sounds easy enough, right? There were some problems though. A thread. #MyElixirStatus

It’s clever optimization called an improper list used for some tricks in building deeply nested io lists. There’s some info about in around the internet if you search for it.

This comes from Erlang, Elixir just models it

I had redirected some sponsorships but will be back to committing to Gleam. Thank you for making the BEAM community approachable to so many people, Louis. Gleam is the dream!

v0.3.0 of Lua has been released with support for guards in deflua functions. We also add guards for checking encoded values in function arguments such as `is_table` and `is_userdata`

Maybe there could have been a more unique name, but I think your concern is a bit overblown in reality.

There’s also a ton of other (arguably more useful) tools than :observer

During my part of the talk, I describe the problem we're solving at TV Labs, and how Lua / Luerl enables us to solve it in an elegant way

Lua on the BEAM, a talk I gave with @rvirding.bsky.social at last year's @codebeam.bsky.social EU has just been published!

It was an honor to speak with Robert, and a reminder for just how cool Luerl is
