We released Pi 1.0! earendil.com/posts/pi-1-0/

beef is negative food. you turn 1000 calories of feed into 100 calories of beef and a whole lot of methane and cow shit. ai does produce more food than the beef industry (zero)

Great track by Spencer Krug from Twenty Twenty Twenty Twenty One: pronouncedkroog.bandcamp.com/track/my-mus... Which pairs really well with this one from This One’s For The Dancer & This One’s For The Dancer’s Bouquet: moonface.bandcamp.com/track/okay-t...

This means I can say I work at both an #ElixirLang and #LocalFirst company now, right? 😏 Congrats @electric.ax team! electric.ax/blog/2026/08...

hmmm

All ICE funding should be transferred to MRNA research and development . www.wsj.com/health/pharm...

"I'll get back to you on that last question when I'm back at my work computer, the documents I need are there" <- as if Claude is waiting impatiently, looking at its watch, wondering when I'm going to get around to supplying its requested information.

I thoroughly enjoyed this review. Both as a piece of writing in and of itself and because it articulated a lot of the things I found frustrating about the film.

It has been a lot of fun working with Omnigent in the weeks since its release. Policies were the component I had the least reason to use in my daily coding use, but I still wanted to understand them. I tested & wrote up a few different ways to use policies here: www.danliden.com/posts/202607...

Benchmarking Coding Agents on Databricks’ Multi-Million Line Codebase They ran a comprehensive evaluation on our tasks, code base, infra. It's been produced by more than 3,000 software engineers, spans 3 hyperscalar clouds and many languages and tasks. www.databricks.com/blog/benchma...

The goal with my rlhf book is to make the "home on the internet" for the next generation learning post-training. That's why I'm doing all formats (lectures, code, book, discord, model completions... & ofc blog of interconnects). A hub is more lasting than non-fiction writing. Join! rlhfbook.com

Another quick lecture -- I've been asked many times for prereq's to my book and what you should know, so built a little lecture (with GLM 5.2) to cover some more basics. youtu.be/MMDNaeIFVy8

Given today's LiteLLM supply chain attack, what are people's preferred development environment sandboxes on MacOS these days? I think it's time I started running my development environments somewhere where rogue code can't steal all my ~/... credential files

A reminder to the news media: “conflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.

Wrote up a short post on how I use registers to save window configurations in #emacs. It's simple, but it's something I've used daily since discovering it. www.danliden.com/posts/202511...

Good things are possible and we don’t have to settle.

Playing around with #emacs org-mode tables. I ultimately want an easy system where I can use capture templates to easily log new rows of data to tables in particular buffers/files.

Every so often I rediscover the immense usefulness of registering window configurations in #emacs . <C-x r w> to register the configuration, navigate away, return with <C-x r j>. Much easier than trying to reconstruct a complicated window arrangement after e.g. deleting windows.

Use AI to debug AI! 👏 With MLflow 3.4’s MCP server, Claude can query MLflow traces to compare runs and identify issues. @danliden.com’s post covers setup and examples in minutes. Learn more: www.danliden.com/posts/202510... #opensource #mlflow #oss #MCP #claude

Enjoyed this post by @matthewsanabria.dev on Taste and AI: matthewsanabria.dev/posts/you-ha... As the post notes—there's been a lot of discussion about the role of taste when working with AI & the idea that some notion of "taste" is what gives humans an edge. It's important with or without AI!

MLflow has added an MCP server in the most recent release, MLflow 3.4.0. You can e.g. use natural language to find and diagnose failing agent traces w Clauded Desktop. This is a huge step toward making MLflow a tool usable by agents. Blog on setting this up coming soon. #mlflow #ai #agents

Seems like this is a common experience at this point—I ran into an issue where Claude Code was struggling, switched to Codex and was able to resolve it quickly. But the UX of codex is much worse in its present form. Still—really incredible to have have both these tools to work with right now!

My #Emacs Elevaror Pitch (#August #Blog #Carnival): Me: Have you heard of Emacs? Me: On the surface, it looks like a text editor… xenodium.com/emacs-elevat...

Anyone regularly use #emacs ediff? I just used it to work through a (simple) merge conflict and it was quick and easy, but I've never really invested the time to seriously learn it. Worthwhile?

As OCR + transform can really shave effort from grunt work. An example xenodium.com/a-platform-t...

Looking forward to this session! MLflow 3 has introduced some fantastic tools for GenAI Evaluation and observability and Yuki is an excellent speaker on this topic.

I updated my note on how to use Emacs for Python development with a couple of new sections: - Using Python in org-babel - Using a src file + REPL development approach for Python in emacs www.danliden.com/notes/202411... I would love to hear how others use Emacs for Python! #emacs #python

"I think we need more tools like Magit: things like lazygit, lazydocker, tldr, LSP, etc. all extend users’ understanding of systems whilst not keeping them too far from the source." Great post by Ashton Wiersdorf. I hadn't thought of Magit that way before. lambdaland.org/posts/2025-0...

Boost observability in your #GenAI workflows with #MLflow Tracing! 🚀 In this hands-on session, @danliden.com shows how to set up tracing, organize data, work with multiple providers, and debug complex agent workflows. 🎥 Watch the full tutorial: www.youtube.com/watch?v=X5P-... #opensource #oss

Well worth reading if you use MLflow and work with image datasets!
