Almost five long years of blood, sweat, and tears… and it’s finally here! 🙌 Thank you to everyone who helped and supported me—we did it! 🎉 It feels surreal to finally hold it in my hands 🤗

Funny you should ask! This Thursday, I’m teaching a class on exactly this topic: coupling and cohesion in the era of AI-assisted software engineering learning.oreilly.com/live-ev…
Why no one is writing an article on how Coupling and Cohesion is impacted by the AI Agents? cc: @vladikk

Pls welcome @vladikk to #YOW26! Vlad will look at why so many approaches to modularity haven't quite delivered on their promises, & share a practical way to evaluate the modularity of your own codebase, identify where things have gone wrong & start fixing them.

Yes, macOS Spotlight, when I type `1pa`, I definitely don't mean the app that I access a dozen times a day (1Password) What I really want to know is how many inches of mercury 1 pascal is. Someday I'll memorize this. Until then, thanks for having my back.

The biggest threat to software engineering isn't AI. It's the software engineers aren't curious and no longer think critically.

So big balls of mud, especially distributed ones, are the pinnacle of software engineering. These are weird times…
If you understand your whole codebase, the codebase isn't that important. Real software is larger than what your brain can comprehend.

『ドメイン駆動設計をはじめよう』の増刷が決まった(6刷)。 ロングセラーの仲間入りかな。ソフトウェア設計やアーキテクチャの考え方を学ぶには良い本だと思う。 原著者 Vlad Khononov さんが11月に来日して講演されるタイミングでの増刷になった。

Apple removed the text on many of the keys on the new Magic Keyboard Now they're all variants of arrows 😵‍💫 I'm sorry, but this is just bad design

Opus 5, Medium reasoning. I have a skill that explicitly asks to use a dedicated skill for creating a PR. The agent ignored the instruction. The reason? ¯_(ツ)_/¯ But the coding is definitely solved, folks!
