What I got instead was a teammate. One that argues, makes silly mistakes, forgets things mid-conversation — but somehow helps me ship production-grade Rust faster than I ever could alone. Over the past few months,..." current

A Wishlist of Sharp, Friendly Tools Created page with "500px Rust is a little like rock climbing with a great belayer: you’re safe, but you will feel the pump. The compiler has your back, the ecosystem is growing up fast, and yet… there are still those tiny paper cuts and once-a-week yak shaves that add friction. So here’s a fun thought experiment for the community: if you could wish for a piece of software, tool, or crate that doesn’t exist yet (or doesn’t work well enough),..." current

A value was used in the wrong unit, a function was called with an uninitialized object, or a simple null check was missed somewhere deep in the logic.
