Finally finished my "bug-hunt trinity" - finding a bug in every major (backend-) programming language I've used! I now got Ruby, Erlang and Elixir. Thank you everyone for your great work! 💚 github.com/elixir-lang/el… #MyElixirStatus

We're meeting today at Lufthansa Innovation Hub! There will be some food (wraps, sandwiches). We'll dig into Retrieval Augmented Reality and mechanical sympathy with Amr Abdelwahab(عمرو) and Tim ! You can also give a lightning talk! rug-b.de/events/novembe…

Saying you don’t need Erlang/Elixir because you have k8s, is like saying you don’t need to restart applications, you will just shut your whole machine off and on.

Should be time to finally move off of this ever increasing hole. Mastodon hasn't quite worked for me, blue sky seems nice and feels a lot like old Twitter.

This afternoon I submitted an issue to the @JRuby team. Five hours later they had the fix ready to merge. I'm seriously impressed.

I want to share something I built for the Elixir community: elixirevents.net✨ I want to make it easier to find events like conferences and meetups, to help the community grow. For feature requests or feedback please let me know! 🙏 #myelixirstatus #elixirlang

There won't be a December meetup, sorry! Happy holidays and then a "guten Rutsch" to everyone. We'll probably see you in January!

🎙️ Luís Ferreira spoke with Tobias Pfeiffer about his decade working with Elixir. Tobias and Subvisual go way back—he spoke at RubyConf Portugal in 2016! The conversation brought back memories of how he was using and advocating for #ElixirLang even then. #MyElixirStatus youtube.com/watch?v=_-645Q…
