Thank you to the kind Chattanooga Enthusiast who was able to get my Elixir shirt to me from Goatmire.

Made my day 😀

#elixirlang

I hope some of these disaffected #Ruby folks will give #ElixirLang a fresh look

So many Elixir developers come from Rails including Elixir's creator José Valim

The ecosystem is growing, it's inclusive (me <- 🏳️‍⚧️), and we could 100% use your energy and your devotion to developer happiness

My copy of The BEAM Book arrived 😀

It's chonkier than I imagined but fits nicely with my other desk references

npm debug and chalk packages compromised The popular packages debug and chalk on npm have been compromised with malicious code

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!

Tons of npm packages compromised. Make sure to check your apps and local envs too, especially if you do anything crypto-related.

It's happened.

My muscle memory now defaults to "behaviour", even when not in my IDE.

I'm actually curious how you came about 3k lines of Erlang, that's quite a project!

DYK - Using (a)bort in iex is a 'normal' exit.

Reminded me of this:

had a timeshift backup go haywire on my laptop;

Cursed but hilarious

Wrote a small library to play with rendevouz hashing, similar to HCA Healthcare's Project Waterpark from @bryan-hunter.bsky.social , and a visualization in @livebook.dev to show actor placement and replication across the cluster, based on the ID of the patient (or actor) @elixir-lang.org
