The top advice given to anyone wanting to get better at writing, besides just writing, is to _read_ more. Especially good writing. Because we imitate that which we experience more of.

Our thoughts about the future of version control

A short intro for now: since hyper stabilized 1.0, it powers more, and needs more. Large improvements lacked a clear path for proposal, scrutiny, and decision. So, hyper Improvement Proposals (https://hyper.rs/contrib/hips/0001-hyper-improvement-proposals/), or HIPs.

How & why we're running cargo-semver-checks in Rust's CI

I dislike the pattern in some languages to create durations by multiplying constants. It feels like a concession when it cannot be expressed more nicely. There's a tracking issue (https://triagebot.infra.rust-lang.org/gh-comments/rust-lang/rust/issues/57391) to add such constants in libstd.
