@AkitaOnRails E se fazer e publicar no nostr? O nostr ja não resolveria essa parte de reputação?

I love running "hail mary" prompts like this.

A few weeks ago I prompted Opus to find code loading optimizations in the Erlang/OTP code base. It came up with 6-7 options, 3 of which I could automatically discard, and I asked it to build experiments for the remaining ones.

Out of those, 1 was clearly successful, which I then wrapped up and now Erlang/OTP 29 will boot 10% faster for everyone.

/autoresearch from @karpathy seems to package this experience into a tighter loop and, if it can find something meaningful, it stands to benefit everyone, especially on OSS. Can't wait to try it and maybe "hail mary" a few other optimizations.

non elixir minds cannot comprehend just rpc'ing prod and introspecting state/debug inside the running vm. Now attach that to an AI agent (w/ human in the loop) and you have insane capability. "xyz seems bugged, use fly ssh -C ... to poke the release to debug it"
No MCP required.

Very suspicious that OpenAI and Anthropic both dropped major announcements within hours of me publishing this: https://t.co/UI4qZiTsxH

They want to silence it. Don't let them. Read it twice. Share it with your colleagues and friends.

Here is my take on why Elixir is the best language for AI: immutability, documentation, stability, and tooling for coding agents.

It builds on the recent study in which Elixir had the highest completion rate across models among 20 different languages.

Just pushed another compilation time improvement to Elixir. 3 years ago, Livebook took 6.4s to compile, it now takes 3.2s. Same machine and the codebase grew in size since.

Most of the gains came on v1.19 but the latest changes helped us cross 2x. Coming on the next v1.20 RC.

Today we celebrate 15 years since Elixir's first commit. To mark the occasion, we shipped an early release candidate for Elixir v1.20 which has TYPE INFERENCE FOR ALL CONSTRUCTS.🎉

In the latest article, I break down the next ~15 weeks and the challenges for the next ~15 months.

@levelsio Yesterday the mouse/trackpad click of my MacOS stopped working totally. It wasn't easy to restart to try to fix the issue.

My connection is so bad I'm unable to check the speed:
