Dual-loop BDD is the new Red-green TDD

This one goes out to all the testing neophytes who only recently realized that it's useful to have an automated means of verifying their code does what it…

Great post on Anthropic's C compiler by an actual compiler expert https://www.modular.com/blog/the-claude-c-compiler-what-it-reveals-about-the-future-of-software
Modular: The Claude C Compiler: What It Reveals About the Future of Software

Compilers occupy a special place in computer science. They're a canonical course in computer science education. Building one is a rite of passage. It forces you to confront how software actually works, by examining languages, abstractions, hardware, and the boundary between human intent and machine execution.

Highly recommend this post. It perfectly captures the internal conflicts and mindset shift I’ve gone through over the last 2 years of coding with AI.

Thanks for sharing this, @mattiem! It sparked a great discussion on AI and its real-world applications. Worth reading the whole thread.

PSA: Did you know that it’s **unsafe** to put code diffs into your commit messages?

Like https://github.com/i3/i3/pull/6564 for example

Such diffs will be applied by patch(1) (also git-am(1)) as part of the code change!

This is how a sleep(1) made it into i3 4.25-2 in Debian unstable.

Almost freaked out when I saw this, thought it could be a new VSCode feature.

Turns out, it's a special ligature feature of the Maple Mono font https://font.subf.dev/

Apple engineers get IDEChatInternalAllowUntrustedAgentsWithoutUserInteraction, while us peasants need to click "allow" 100 times a day

"A common fallacy is to assume authors of incomprehensible code will somehow be able to express themselves lucidly and clearly in comments."

"... or prompts." I would like to add.

Pretty much agree with most of this: If users notice your software, you’re already a loser https://pivot-to-ai.com/2026/01/10/if-users-notice-your-software-youre-already-a-loser/

Nobody wants a computer. They want what it does. Not the annoying machine. Including phones. I just got a new phone, a Fairphone 5. It’s a nice phone! And Fairphone will even sell you it with the G…
