My latest example: Over my career, I’ve personally performed a few thousand code reviews of PromQL (neé Borgmon). Any issues I catch can be distilled down into a handful of categories, none of which I consider exotic. ...

LeetCode-style interview prep has a hidden assumption baked in: that for any unfamiliar problem, you can quickly spot which algorithmic pattern applies — even though most problems admit more than one valid approach. Grinding through exercises doesn’t really train that skill on its own. So I built a small tool to practice it directly: it pulls problems from LeetCode, then quizzes you multiple-choice style on which pattern fits before you ever write code. ...
