Engineering a chess match against my brother

This is the story of me trying to win a game of chess against my brother. A single freaking game. What’s so special about it? Am I good at chess? Not at all. Did I improve at my game in the process? Also no. Is it a story about “the journey rather than the destination”? Not really. Did I at least have fun in the process? Not so sure.

Ripgrep code review

I’ve been playing around with Rust for a year and a half, and the best part of it, like many others say, has been the very helpful community. There are a lot of online resources that help you to get started: the Rust book, the Rustonomicon and many blog posts and stack overflow questions. After I learned the basics I felt a bit lost though. I couldn’t find enough resources for intermediate-level-Rustaceans....
