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 🥣
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. youtu.be/h_WAPbfur7M ElixirConf US 2026 Early Bird tickets: elixirconf.com

“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: github.com/elixir-lang/elixi… 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.

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 🤘 speakerdeck.com/georgeguimar…

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.) 1/

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🚀 #myelixirstatus

Sad to announce JNGL will be retiring on the next epoch, 620. It's been a fantastic journey and I've met many amazing people through the SPO community. Thank you to our delegators for the trust and support, and please consider re-delegating to one of the @AllianceXspo members 💚

I know there is some overlap between open source and anti-AI activists, but I have a hard time reconciling it. My million open source LOC were always intended as a gift to the world. Yes, I would make arguments about how it would strengthen our communities, and the GPL would prevent outright exploitation by our competitors, but those were to allay fears of my partners to allow me to make the gift. AI training on the code magnifies the value of the gift. I am enthusiastic about it! Some people do look at open source as a tool for social change, career advancement, or reputation building, but those are all downstream of the gift.
Genuinely devastating take to see from someone who popularized the GPL across so many communities. Fails to appreciate the social and cultural importance of the license.
