Most bugs aren't from bad code — they're from **missing states**. Statecharts + actor models saved me from endless edge cases. For the next 90 days, I'll share one insight a day on how actors + charts make complex systems simple. Feel free to follow along.

Please stop mixing source and derived state in your domain objects. I know it's convenient, but it risks drift and subtle bugs. Instead: - Keep only source of truth in your model - Derive everything else when you need it

If you're vibe coding, ALWAYS implement tests first and create rules to enforce proper type safety. Here is my go-to prompt I tend to re-use throughout my workflow whenever I need to reset the context: "Avoid `any` types and if necessary, replace with `satisfies`. Do not

SolidJS makes more sense if you use XState or an actor-based model in your apps. React had its run, but it doesn't make sense for me to use it anymore.

Web Dev has so many nice things. Latest discovery: Wallaby. Runs tests in the background, shows state right next to the code.

Wallaby runs your JavaScript and TypeScript tests immediately as you type in VS Code, WebStorm and other editors, highlighting results next to your code.

Also, AI absolutely is a blessing. Incredible what it can do. Incredible when it Just Works. But we're still a million miles from AI obsoleting all programmers. And it doesn't feel like we've gotten that much closer to the promised land in the last 6-9 months.

This is awesome. Pair-programming with AI agents ("learning" mode) is going to result in higher-quality, more maintainable code. Don't go full autopilot with AI coding agents. Not worth it IMO.
Today we're launching new ways to learn in Claude Code and the Claude app. First up: Claude Code now lets you customize communication styles with /output-style

You have no idea how fucking amazing this is. 90% of people don’t act on their ideas. And for the few who do, 90% give up too early. Making $1K/month with little startups built solo is already top 0.1%. The problem is social media only showing you the top 0.1% (the guys
Lately I've been feeling a sense of failure, burnout, and emptiness. My two main products (blawgy and foodbuddy) both make some fun money (blawgy at ~$600/mo, foodbuddy at $150/mo). Just two weeks ago I signed a contract with a F500 on another old project for $10k/yr. When I
