My @blastoffrails.bsky.social talk is live! youtu.be/ZBrBMC_sH2A?...

For AI-assisted Rails work, I'd prioritize request specs that try to read and update another account's records. "Always scope queries by account" in AGENTS.md is useful context. Even more useful if you can give CI a way to reject the code when the agent forgets.

I would give my worldly possessions away to work with Drew again on an engineering team. Hire him. Or tell a friend. And have them tell a friend he's on the market again.

A group of top-tier Rails developers I know and worked with (plus myself) were unfortunately laid off today. Any company would be fortunate to pick them up. If you or anyone you know is hiring, send me a DM 🙏

Hire Drew before your competitor does and you have to sit through a meeting about why they're shipping faster.

ZJIT is now as fast as YJIT: railsatscale.com/2026-10-09-z...

Ruby 4.1.0dev on Windows (mswin, not mingw) is getting faster. On the ruby-bench headline benchmarks, the 4.1 dev build runs 1.32x faster than 4.0 without a JIT, and 2.19x faster with YJIT, which now works on mswin. Stay tuned for the 4.1 release.

blue looks good on everything

Thought I’d catch up on the vibes before going back to work on Monday so I listened to the latest episode of Remote Ruby: www.remoteruby.com/2260490/epis... Well, now I’m depressed @andrewm.codes

Got paged just as I was falling asleep. By the time I reached my laptop, production had recovered. It's almost 5am and I haven't. Love a self-healing system. Would love to be one. Gonna be a long day. 💀

I got a haircut today and the lady asked me if I was stressed and then proceeded to tell me she could feel tension in my head. wtaf.

Hard to believe how much is hiding in the sky until you get somewhere dark enough to see it.

I put Claude to work…

Sir, a second GitHub Actions budget limit has hit the account 💀

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...

Just gave one of my older #Ruby posts a 2026 refresh: automating gem releases with GitHub Actions. It covers using Release Please for version bumps, changelogs, GitHub releases, and publishing to @rubygems.bsky.social andrewm.codes/p/automating...

I exported all 358 of my Pieces code snippets into Obsidian. I wrote up how I built the exporter, including the raw archive, normalization layer, deterministic filenames, metadata cleanup, SHA-256 verification, and the weird edge cases. andrewm.codes/p/exporting-...

Nothing good has ever started with "I'm in Scottsdale at 1am" but here we are.

Also: Ryan is building Knowatoa, which helps you see where your company is showing up in AI search and how to make sure you show up more. If you care about how ChatGPT, Claude, Perplexity, etc. talk about your product, check it out: knowatoa.com

My code vs. AI bug bounty farmers

Just booked my flights to #RailsWorld and after seeing the total, I'll be standing ten toes down on this issue for the foreseeable future.

New Remote Ruby is out. @davidhill.dev and I talk about my recent dive into MCPs: the Ruby MCP SDK, resources vs. tools, OAuth with Doorkeeper, and what I've learned building an MCP server for Rails. Plus, we're getting ready for Rails World in Austin. www.remoteruby.com/2260490/epis...

Happy and grateful to find Remote Ruby #1 again 🥳

I'm gonna be driving over 1000 miles this weekend. Please provide audiobook recommendations ⬇️

waking up to the sky

I was kicking off a project today that I thought might be 4-6 weeks of work when @andrewm.codes _eventually_ interrupts to tell me they’d basically built the entire thing in half a day. Tell me again that AI hasn’t changed this industry faster than we can adapt

90 days. New codebase. Shipping value while still figuring out where the service objects live. Andrea Fomera's field report on AI-assisted onboarding is the playbook you didn't know you needed. Get your early bird ticket still! rockymtnruby.dev/tickets

New Remote Ruby is out. @inazarova.bsky.social and @palkan.bsky.social join us to talk SF Ruby 2026, what they learned from year one, building startups with Rails, open source, AI, and the Ruby companies quietly doing interesting work. www.buzzsprout.com/2260490/epis...

I have been watching Rick & Morty since season 1. Season 9 is easily the greatest season they've done since the early days.

Can't remember the last time I was in a movie theater but I saw the new Spider-Man and was not disappointed

🎙️ New Remote Ruby is out! We finally gave the show a new intro, so let us know what you think. This week’s episode covers RubyConf, Raspberry Pi side projects, MagicMirror dashboards, AI, Battlefield 6, IPv6, and a surprising amount of air conditioning. www.buzzsprout.com/2260490/epis...

Finished Smallville in under 2 weeks. They should have stopped after season 7. Everything after just pissed me off.

Genuinely, I find myself working harder. One of my super powers was I was faster than you at designing & writing what I needed to. I needed that time saved to be able to regulate, avoid burnout. Now that’s taken from me. I can’t outpace you. You (proverbial) got to catch up to me for free.
