Man, I felt invincible on today’s parkour training ✊🏃‍♂️ It gives me so much energy when I’m basically trying to be a ninja, compared to calisthenics where I’m mostly suffering just to gain extra muscle.

This really lowers the entry barrier 🙌 I can now skip Delta UI and have AI multiplayer in the Terminal or within Zed.

I recommend this course, it took me from zero to building an internal library of web components. Web Components are one of those web concepts I was failing to quite grasp, and I feel like people are still discovering what to use them for. As a next step I'm looking at exploring elenajs.com/start/

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)

This is true. Fable 5 and now Opus 5.5 and Fable 5.1 reliably write code that’s as good as if not better than I would have written myself. And they do it 100 times faster. They’re not making “slop” or tech debt. They’re creating high quality tested, maintainable software that works.

Me too! What are the odds? 😃

Because I chose Vite over the DHH-blessed importmap/jsbundling-rails, I was now able to add a Vitest suite covering our Stimulus controllers. It seems like a good alternative to Capybara tests on Chrome, which are just slow. I’d gain nothing from #nobuild, while Vite only costs a < 1s build.

Great news, everyone! After a TON of work, #RuboCop 1.92 is out with many improvements that make it play better with AI agents (and many other fixes and enhancements). Read all about those here metaredux.com/posts/2026/1... Feedback welcome! Enjoy! #Ruby

Hey, Rails peeps. Hot Cell is a suite of gems that helps you secure Active Storage against image library zero-days. I just released v1.0! mike.daless.io/posts/2026/1... Links to Rails World video and slides as well as the project repo and docs are in the post.

Wrote a thing about last week's Rails World. andycroll.com/ruby/look-a...

Thanks to the new language server features added to Herb 0.11, I could now close my PR to ruby-lsp-rails 🙌🏻 github.com/Shopify/ruby...

Hot Cell is ready to go if you're on Rails edge. Slides are up at mike.daless.io/prez/2026-09...

I'm honored and humbled to join the Rails core team. I'll be focusing on security and improvements to Active Storage and Action Text. Please reach out if you have thoughts on what would make your work easier.

The amount of new features and improvements is massive 😃 Besides the awesome reactivity features, I love the language server improvements, such as ability to follow render calls (I can close my ruby-lsp-rails PR now 😄) and listing render call sites for current partial 👌 github.com/marcoroth/he...

Today is a big day for Herb! It's built into Rails 8.2 by default for all HTML+ERB views. My talk at #RailsWorld in Austin today answered three questions: What is Herb? What ships in Rails 8.2? And what does this enable? Herb v0.11 and ReActionView v0.6 released alongside it.

Interviewer: "Where do you see yourself in 5 years?" Me:

Multiple tools using Rubydex already: Rubocop, Rubydex linter, RubyLens, ArchSpec, Enola... Still eagerly awaiting Ruby LSP release with Rubydex backend 🤞

New post: I added webmentions to my Bridgetown site. Replies, likes, and reposts from Bluesky can now show up directly under the original post. No comment system, no JavaScript widget, and the site stays completely static. I wrote up how it all works: andrewm.codes/p/adding-web...

Last call: EuRuKo 2026 tickets close tomorrow at midnight CEST. @matz.bsky.social opening, @ko1s.bsky.social closing, @headius.bsky.social on JRuby. Brno, Sept 17–18. After tomorrow there's no late registration. 2026.euruko.org

Here is a summary of my frustrations with MariaDB in my past jobs and why I wouldn't recommend it for production. www.reddit.com/r/rails/comm...

RuboCop 1.91 is out and it's the most interesting release in quite a while. Try some of the new features like `--diff`, `--changed` and `--preview` and read all about the improvements here github.com/rubocop/rubo... #Ruby

🚨 Announcing Pushin 🚨 Now officially: I'm announcing Pushin.eu, a git hosting platform built and run entirely in Europe. Think GitHub/GitLab but European, better, and faster. Built with #ElixirLang and #RustLang. peterullrich.com/announcing-p...

For a long time I was trying to figure out whether the solution to my back pain is increasing flexibility, strengthening back & core, improving hip mobility, or doing frequent walks/runs. And now I think the answer is just “yes”.

Two weeks out from EuRuKo 2026. Brno, 17–18 September. If you're still deciding, the flights are deciding for you 🎟️ 2026.euruko.org #Ruby #EuRuKo

Booked the jj workshop by Andre and Kasper. I will finally see what all the rave is about 🤞

Cool, you can now just wait for a certain write to be replicated before querying the replica. I can imagine automating this in Active Job, where current WAL state is serialized into the job and waited on. That way it should always be safe to read from replicas in jobs.

Here’s the SolidQueue batches 2.5 year architectural journey, filled with O(n^2) algorithms, hot row contention, excessive jobs, and much in between. There’s a strong chance you’ll learn a thing or two - I certainly did 😮‍💨 jpcamara.com/2026/08/31/s...

This is the feature I missed the most from fugitive.vim, I finally have it in Zed now 🙌

🚀 Zed v1.17 is out! Zed now previews CSV, TSV, PSV, and SSV files as interactive tables. You can sort and resize columns, then filter rows by selected values. Thanks HalavicH!

Having also read the linked article, I realized enqueueing background jobs after commit isn't guaranteed. First thought was that SQL-based background libraries implicitly provide the transactional outbox. But at any serious scale a separate DB should be used. karolgalanciak.com/blog/2022/11...

Lexxy doesn't currently export its *.css files, so I can't import the CSS with Vite. Strange that this hasn't been addressed yet. github.com/basecamp/lex...

The docs on SolidQueue batches are… solid 😉 In addition, I wrote up this blog post to dig in a bit further on how to use batches in SolidQueue, including some code inspiration - like splitting a RubyLLM chat into parallel sub agents using batches jpcamara.com/2026/08/24/a...

It turns out having Rodauth render Inertia.js components is pretty simple ✨ github.com/janko/rodaut... github.com/janko/rodaut... I let Claude lead me down the wrong path multiple times, thinking the integration would be more involved. In hindsight, I would've been much faster without AI 😅

Target Multiple Classes with the Class Prefix Selector: .btn-* { … } Yes please! (Coming soon) Great post by @bram.us: www.bram.us/2026/08/20/t...

More Git goodness, coming to Zed! github.com/zed-industri...

Today we’re introducing Delta. Delta is a multiplayer environment for coding with agents and reviewing what they build, powered by DeltaDB. The first invites to our private beta are going out now. zed.dev/blog/introducing-delta
