Credo 1.7.15 is out now, with massive perf improvements for large #ElixirLang codebases.
Got a few PRs in flight for Credo which cumulatively dropped the runtime from ~33 seconds down to ~9 on our 3500 file #ElixirLang codebase at work. 😁

Working with Beads + Tidewave to create a new Phoenix app to automate manual tasks I've been handling for Elixir Radar.
Current flow:
- While Tidewave pulls work from Beads
- I spec a new task by asking Claude to ask me questions about it
Keep the cycle and profit 😜

Don't get me wrong, building web apps is immensely fun (especially if you are using LiveView). But building a physical circuit and interacting with it just hits differently. I've been having a blast putting together the Programming Nerves projects 😁.

Saturday mornings are set aside for writing "Financial Analytics Using Elixir". And I must say....I'm really pleased with how the analysis framework is coming together 😍. @livebook.dev and its supporting tooling is such a nice fit for this!

Livebook runs each notebook on its own BEAM node, connects to Phoenix apps transparently, and spins up runtimes on remote machines. How?
Just submitted a talk proposal to @Elixir Conf Europe to explain this. 👀

We believe text is not enough when you want the agent to make UI changes.
With Tidewave's new Inspector, you can point at multiple elements so your agent knows exactly what you mean.

A highly experienced beginner. Ellyse Cedeno took us through her journey with getting into hardware using Nerves after many years of Elixir development.
No reason to be afraid of NervesConf EU. Keep an eye out for more from Ellyse, she is awesome.

Hi Elixir friends,
After 3 years on Hologram full-time (transpiles Elixir to the browser), I'm at a crossroads.
60+ hr weeks balancing contracts & dev isn't sustainable.
