As I’m approaching 2026 and reflect on what’s ahead of me, I like to come back to first principles: 👉 optimising for happiness 👉 optimising for challenging work 👉 optimising for positive dent on the universe Not in a self-help way, but as a selection mechanism.

Wow 😀 Just got my first NON-FRIEND subscriber to Compiled AI! Feel like such a great milestone. Someone who doesn't owe me any favours actually thinks my #AI newsletter is worth their time. Sake bar, here I come! 🍶🎉

#AI is 90% artificial, 10% intelligence. We’re building very sophisticated autocomplete systems and calling them intelligent. Don’t get me wrong—they’re useful! But let’s stop pretending they ‘understand’ anything. The magic is in the engineering, not the intelligence. 🤖

I still think that running containerised apps in a simple way is an unsolved problem. Am I wrong? What would you use to run a single container?

That moment when you realize you've been doing pwd → manually copying the path like a caveman 🦴 Just add this to your shell config: alias pwc="pwd | pbcopy" Now "pwc" instantly copies your working directory to clipboard. Such a simple thing but it genuinely sparks joy every time I use it.

🔥 The ability to keep chatting with Claude Code whilst it's executing tasks is a bigger deal than it sounds. Every other LLM blocks input during execution. Claude Code just... doesn't. You remember something? Add it. Requirements change? Update them. No restart needed.

Been running pre-commit hooks alongside #AI coding assistants for a while now, and it's genuinely a game-changer for code quality. The secret sauce? Make "--no-verify" a forbidden phrase in your rules.

If you make a favicon for your new project, you deployed too late. If you don't, it looks shit. So, I just make favicon.svg as a circle using brand colour as background. It takes me no time, and looks much better. #buildinpublic

The most annoying "feature" of Claude in desktop app by far is the fact that it is not great at rewriting and updating documents. It messes them up a lot, to the point that I have to ask it to write it from scratch.

I think the key is using #AI tools like Claude Code to free up our mental bandwidth for the higher-order thinking. In my experience, when Claude Code handles the routine implementation work - migrations, boilerplate, refactoring - it gives me more headspace to focus on:

Honest take on Anthropic Claude Code after weeks of daily use 🤖 Finally feels like working with a proper developer instead of fighting with a tool. What actually works: ✅ Learns from mistakes (keeps a memory file) ✅ Respects your workflows consistently ✅ Integrates seamlessly with other tools
