🥳 Another open source library announcement 🥳
Just published github.com/akoutmos/math_jax so that you can render MathJax expressions to PNGs/SVGs from Rustler! I needed this to inject math expressions into PDFs generated by ChromicPDF. See sample below 😉

Been hacking on an Elixir port of @karpathy's autoresearch — an LLM agent that designs and trains GPT models autonomously, overnight. Turns out the BEAM is (unsurprisingly) a natural fit: hot code reloading for experiments, multi-GPU fault tolerance, LiveView to watch it think.

We have converted our Livebook Desktop app to Tauri. If you're using Livebook, please give it a try by downloading the nightly builds: github.com/livebook-dev/live…
Our goal is to extract the Tauri integration as a separate package to make it easier for people to ship Tauri Elixir.

It's been a long day of writing and programming, but I think everyone that picked up a copy of Programming Nerves (programmingnerves.dev/) will really enjoy building the Etch A Sketch project 🎉!
@NervesProject @livebookdev = ❤️

I'm at Joe's famous "make it beautiful" part for the Programming Nerves Etch A Sketch project 🤩. Pretty cool that you can do all this inside of @livebookdev and @NervesProject.
Pick up your copy today at programmingnerves.dev/

We extracted Nimble ZTA (Zero Trust Auth) from @livebookdev as a separate package for Plug/Phoenix: dashbit.co/blog/zero-trust-f… - basically, the simplest way to add auth to an internal app when your identity management and deployments are on the same platform (GCP/Cloudflare/etc).

Saturday mornings are set aside for writing "Financial Analytics Using Elixir". And I must say....I'm really pleased with how the analysis framework is coming together 😍. @livebookdev and its supporting tooling is such a nice fit for this!

Last week we used tidewave.ai to find accessibility issues on @37signals's Campfire (Rails), @shadcn's UI (Next.js), and our own @livebookdev (Phoenix), and we were able to automatically fix 79% of the issues we found, 2x more than using Claude Code standalone.

@hugobarauna and I are hard at work preparing the Beta release of Programming Nerves. Every @livebookdev project in the book comes with a notebook that includes the wiring diagram and code 🤩.

Looks like I’m not the only one playing around with financial time series data in livebook. The analytics tooling in conjunction with VegaLite is soooo nice!

Elixir's ecosystem keeps expanding, from IoT to machine learning with Nx and Axon, and now AI-assisted development with Tidewave.
I'm exploring a new frontier for Elixir: Trading.
Just integrated TheoryCraft with @livebookdev using Kino. Live charts, indicators, and strategy logic all in Elixir.

Did you know you can connect a Livebook notebook to a running Phoenix app?
Apparently, many of us don't.
Useful for:
- internal tools
- runbooks
- and engineering support
Here's how you can do it. 👇

I just finished putting together interactive Livebook notebooks for every chapter of Advanced Functional Programming with Elixir.
You can now run all the examples in your browser. Or like me, spin them up locally with Docker:
