The biggest scandal in AI energy right now deserves to be xAI's data center running 35 methane gas turbines that don't need air permits because "temporary" and don't have catalytic reduction pollution controls installed because... they just didn't bother? simonwillison.net/2025/Jun/12/...

Deep Blue is 30 years old and was capable of defeating chess grand champions. It could be housed in a single cabinet. ChatGPT spans untold data centers devouring massive amounts of electricity and it got its ass whipped by an 8 bit gaming console from the 1970s.

Elixir 1.19 is a banger! Honestly I'm so pleased with the direction that #ElixirLang is going. My programs just get faster and more correct every time. I just know that we're in good hands. Thank you to everyone on the team for your hard work! github.com/elixir-lang/...

Annoying problem with #Sidekiq. When running tests sometimes some of tests fail with NameError: uninitialized constant Sidekiq::ScheduledSet while sometimes it all goes well. I suppose I have some problem in the tests setup but cannot figure out what it is.

Really excited to share this one - I arranged the PCB factory tour in China because I ordered the first production batch of Soleil boards there. This clip shows me unboxing the boards in the shipping room of the factory. They turned out absolutely great, really impressed with the quality

I've just released Handoff, a new Elixir library for distributed function graph execution. hexdocs.pm/handoff Among other things, the library enables distributed Nx computations (anyone said distributed inference?) A huge part of this was sponsored by tvlabs.ai!

Klarna made waves replacing staff with AI, but now it’s rehiring humans after quality dipped. They are still “AI first” by not replacing employees who leave given AI. I like to think of this as “hiring freeze first” instead. It’s more honest.

llama.cpp shipped new support for vision models this morning, including macOS binaries (albeit quarantined so you have to take extra steps to run them) that let you run vision models in a terminal or as a localhost web UI My notes on how to get it running on a Mac: simonwillison.net/2025/May/10/...

Gus Workman's Soleil board is a super interesting piece of hardware for running a Pi Zero for a long time on battery power. It was developed as a Nerves-first project and I'm very excited to see what else Gus has cooking, I know he has a few things coming :) https://youtu.be/G2wTGnElw-8 #elixirlang

Introducing Tidewave: tidewave.ai While working on our web apps, we run code, query the database, read logs, search docs… but our AI tools are limited to reading code. Tidewave closes this gap by introducing Runtime Intelligence, for Phoenix and Rails. More coming soon, check out the website!

What I don't like about #ElixirPhoenix is that with each new release existing applications feel like full of garbage and obsolete code. Too many changes give a feeling that 90 degrees turn is made and almost full application rewrite is needed.
