- Watching videos titled "X is the best model" is a huge waste of time, now more than ever
- This is not what vibe coding means. "It wasn't the code that I would have written, it lacked my character, which made it hard for me to understand it at a glance." matklad.github.io/2026/01/20/v...

- So true. Even spending a day to replace something that costs $100 a year doesn't make economic sense. There are other factors, such as learning or simply enjoying building things, but don't fool yourself. x.com/AveryChernin...
- "I'd like to see more investigation into long-term patterns of AI use in tech companies. Is the slower learning rate per-task balanced out by the higher rate of task completion? Can it be replaced by carving out explicit time to study the codebase?" 🤔 www.seangoedecke.com/how-does-ai-...
- Zig has started to reimplement libc (news.ycombinator.com/item?id=4685...), which is exciting. I asked Claude what this means for macOS, where libc linking is a bit trickier.
