It’s crazy that Claude can build 3D visuals for the anatomy podcast I’m listening to. Everything’s synced with the audio. This is a great podcast called “Dissectible Me” by Sam Webster & Chris Summers. (As I’m not authorized by the author for re-adaptation so this is private for my own learning)

Welp... Got laid off from Podia today. Kinda a lot to process for a Thursday. I'll have something more coherent to say eventually. For now, send Ruby/Rails leads. Or dog pictures.... Both are good.

Went to a streetlifting competition today for just pullup and muscleup. Got this +70kg pull at 62kg BW 🥳 6th UK ranking at my -66kg category as well

Also happy to get this +12.5kg muscle up

st0012.devThe developer growth path has dramatically changedHow AI agents change our career growth, from less control over our tools to unequal learning opportunities and the cost of learning outside work.

With AI agents' development, I'm feeling a dramatic change for my growth path as a software developer. And I think that's something contributing to the industry and Ruby community's anxiety/frustration too. So I wrote a post to capture my thoughts: st0012.dev/2026/10/04/a...

I created a first draft of the @whysfoxes.bsky.social website: whysfoxes.github.io/whysfoxes_web/ Feel free to give me feedback on that. 😊 #whysfoxes #whysPoignantGuideToRuby #Ruby #RubyLang

Having built developer tools for half my career (literally!), I decided to build something “useless” this time. Today I’m announcing RubyLens, a gem that turns your Ruby codebase into a galaxy, as either a page or a video! Here’s an example using Discourse：

github.comGitHub - st0012/rubylens: Turn your Ruby codebase into a galaxyTurn your Ruby codebase into a galaxy. Contribute to st0012/rubylens development by creating an account on GitHub.

RubyLens uses Shopify’s Rubydex to map classes, modules, tests, and dependencies. It runs locally and generates a self-contained HTML file, so your code doesn’t leave your machine. github.com/st0012/rubyl...

st0012.devRuby Galaxies — Four Ruby codebases visualized with RubyLensFour Ruby codebases rendered as live galaxies by RubyLens, with interactive Explorers for every project.

I also generated Ruby Galaxies for RuboCop, Rails, Discourse, and rubygems.org Click any galaxy to open its Explorer and see how Ruby codebases of different sizes form different shapes: st0012.dev/ruby-galaxies/

Hope all my friends in Japan are safe 🙏

RDoc 8.0.0 is out now. This is the biggest RDoc release in years, and it brings together a lot of the Ruby documentation work I talked about at RubyKaigi. Also, RDoc now has a logo!

The biggest visible change is type information next to method documentation. RBS signatures now show up in both HTML and `ri`, and Aliki presents method entries as signature cards.

RDoc 8.0.0 also includes a live preview server, Prism-based parser, a refreshed coverage report, many Markdown/cross-reference fixes, and more Aliki polish. The release note has a short overview before the full PR list: github.com/ruby/rdoc/re...

After weeks of work, Ruby’s master documentation now displays rbs signatures! We will release this feature in RDoc 8.0 soon as well. So any projects using rbs (inline or .rbs files) can benefit from it too. Check it on docs.ruby-lang.org/en/master

RDoc server mode with live reload is almost ready for ruby/ruby. Currently `make html` takes 30-60s and you have to rerun it after every change. With `make html-server`, you get instant live reload. (Just found a bug with page links, but it's getting there) Here is a demo:

First Ruby LSP beta got released with partial migration to Rubydex 👀 github.com/Shopify/ruby... Indexing our Rails application (+ dependencies) currently takes 12s with Ruby LSP's internal indexer. Rubydex does it in 2s 💯 And I think it's even doing more work.

As I sit through yet another russian Shahed attack on Kyiv, I'm thinking of one of russia's most horrific crimes — the targeted destruction of the Mariupol Drama Theater four years ago today. That airstrike killed hundreds of innocent people, mostly women and children who had sought shelter there.
