I dev things

[Carlos Souza @caike]

I was paying >$300/month for accounting software that couldn't send invoices reliably. So I built Zippato.

The video of my talk on using Elixir to write network protocol clients has been published! Check it out if you want to learn how to use the BEAM for network programming - plus state machines, blockchain and açaí 🥣

[ElixirConf @ElixirConf]

WebSockets are easy.
Binary protocols at 2am? Different story.
@caike explores building blockchain protocol clients with Elixir, OTP, and gen_statem at ElixirConf US 2025.

@danielbergholz @sasajuric Be sure to add at least one pg replica for unmanaged. I’ve been burned by corrupted snapshots in the past.

@fseixas já testou o /grill-me do @mattpocockuk ?

[Carlos Souza @caike]

@glcst They should rewrite Rust in Turso

“production software is not judged by how much output exists. It is judged by whether that output is correct, maintainable, understandable, useful, and aligned with what customers actually need.”

We have just wrapped up the meta-issue which tracked type inference of all Elixir constructs: https://t.co/HvOu1Iw9Cv

It includes typing of the construct themselves and features like occurrence typing, to provide a high-degree of precision. Expect a new RC soon as we will continue measuring performance on our way to Elixir v1.20.

[FullstackPhoenix @FullstackPhoen1]

@openclaw So, im looking for a new job or contract in Elixir or Ruby space.

[George Guimarães @georgeguimaraes]

Just published my @ElixirConfEU 2026 slides:

Arcana: production-ready RAG for Elixir.

A serious RAG stack without leaving the BEAM: pgvector, Bumblebee, Nx.Serving, GraphRAG, reranking, grounding, eval.

Thanks to everyone who came by 🤘

@DominikTornow @blinklabs_io you all have been DSTing Dingo with @AntithesisHQ , yes ?

[Pekka Enberg @penberg]

What would a TigerBeetle-like architecture look like in Rust?

For a long time, I have wondered how you would do architecture like TigerBeetle but in Rust. How would you structure your server app in a way conducive to DST?

(Link to proof of concept git repository below.)

@DavidKPiano @ReactMiamiConf @jen_ayy_ The most wonderful state transition. Congrats! 👏🏻👏🏻👏🏻

[benoît chesneau @benoitc]

pure implementation of QUIC in erlang performs well now .

[Kamil Skowron @kamilskowron]

Is anyone doing interesting work with Elixir+ML?👀

I’m exploring new opportunities after my startup didn’t work out. I’m genuinely excited about machine learning and currently leveling up my skills - still early in the journey, but eager to grow and contribute🚀

@openclaw Turns out gemma4 doesn't handle tool calling reliably womp womp so I'm switching to gpt

[Carlos Souza @caike]

Good thing I just switched to using gemma4 for @openclaw 😅
