Something to be cheerful about: @therubypassport.com and the sheriff office! Credit to @thehale.dev ❤️🥹
An image showing a collection of playful, mock "Wanted" and "Have You Seen This Dog?" posters pinned to a dark bulletin board. The posters feature humorous text and drawings, including a "Wanted" poster for answering a beginner question patiently and another for a "big-ish reward" with a smiley face. The central poster shows a photo of a fluffy brown dog with text asking to let "Rosa know you saw her dog."

.@dhh wrote 150,000 lines of code last month, mostly Rust. Number of Ruby Passport stamps that earned him: zero. The embassy stays open all day if he wants to come and explain himself.

NOTICE FROM THE RUBY EMBASSY 🛂 Following yesterday's keynote, the holder of passport #0001 (@dhh) is under review for unauthorized travel to Rust. The Sheriff's office is looking into it. 🤠

200-ish Passports left for @euruko 🚚 We also sent some typical Romanian rum chocolates for the Embassy table. Make sure you grab one while you get your Passport stamped.

Now it clicked for me. The paid gems get their own updates and that messes up bugbot. Heard it loud and clear. 🫡

One thing is for sure: In the winter, our heating bill should be a bit lower, because we now have these powerful computers running coding agents all the time.

It's still not easy to get used to 200-line PRs for things that are functionally 3 lines. LLMs add inline comments, tests, and sometimes docs supporting the change. I know I can steer them. I know it's for our own good. It's just a change. How do you cope with that?

Then I need to manually set up environment variables and scripts—plus decide whether it should have access to the internet, whether it should have caching, and all of that. So archaic! Cursor just works 🙌

Today I wanted to use Codex agent from Linear. I can’t. I assign it an issue, and it tells me I need to set up an environment. So I go looking for how—and why that isn’t automatically set up for me. I end up having to Google it or ask a different app, because it won’t tell me.

Now that's a "normal" PR and we "push through." We started adding CI jobs to highlight how many lines of code are tests and comments, hoping that we can ease the review process.

Adrian Marin @adrianthedev.com · 10/08/2026
This is a shift in how we think about PRs too. Before, a 1,000-line PR would have been considered a big one and would be requested to break it into smaller ones.

Adrian Marin @adrianthedev.com · 10/08/2026
So a PR that would take around 250 lines written by hand can now take up to 1,500 lines.

Adrian Marin @adrianthedev.com · 10/08/2026
One thing we had to acclimate ourselves to at @avohq.io with the new LLM-powered engineering methods was that our PRs would be much thicker, with more lines of code. LLMs (or at least our setup) document things inline much more than we did. Also, the tests are much more detailed.

Non-technical founder with a SaaS idea? You don't need a dev team. At MicroConf US 2025, Avo founder @adrianthedev.com made the opposite case: one developer is enough (if you pick the right one). YouTube link in 🧵:

Using the vibe-coding-way of doing things on pre-LLM projects is really difficult. Not in the sense of using LLMs in coding, but in the sense of "code doesn't matter anymore" and "if it works and the tests pass, then it's all good". I can't do that on those projects.

We're all such AI-pilled that we think that this is not important, while it's more important than ever. The person who watches these and implements them (using an LLM or not) in their apps, will get ahead the most in this "rinse and repeat" we all use the same LLM world.

This is the best time there's ever been to build software. The boring parts get cheaper every month. Avo is where you spend less of your time on the part of your app that was never going to win your market anyway. Try Avo 4 today 👉 avohq.io/blog/avo-4

New pricing too. We unbundled. Every feature is an addon, pick exactly what you need. Then we bundled the common ones at a discount. Start small with Essentials or grab the Everything bundle.

New addons, each one less thing you build and babysit: → Kanban boards → Forms → Reactive fields → Notifications → Collaboration → HTTP Resource (back a resource with any JSON API 🤯) → JSON API (auto-generated REST for your resources)

Keyboard navigation everywhere ⌨️ Browse records with J/K, focus the table with Shift+T, jump around with shortcuts for search, views, actions, sidebar. Hit Shift+? to see them all. It's almost VIM mode for your admin.

The new UI is themable and accessible. Light and Dark Mode, neutral + accent color controls, full themes coming soon. Runs on Tailwind 4 with CSS variables, so you (or your LLM) can shape it however you want.

Avo 4 is here 🎉 15 months, ~2000 commits, and about 50 teams kicking the tires. It's a full redesign, not a fresh coat of paint. A safer way build your internal tools 🧵

All of the things that people say about AI are mostly true. That's the problem and the most polarizing thing. It's not completely true, but mostly true.
