💡 Trivia: What language was used to write the first Rust compiler?
Today's Rust compiler is self-hosting (written in Rust, compiles itself using an existing compiler). But this raises a question: How was the very first Rust compiler created when there was no Rust compiler to build it?

Today I switched my deployment from staging to production using GitHub Environments. Same workflow, but GitHub Actions automatically loaded all the prod secrets and configs. No script changes needed—it just worked exactly as designed. Love to see it!

Cloudflare's biggest outage since 2019 came down to an `.unwrap()` call that "should never fail" - until it did.
Key lesson: "This can never happen" usually means "hasn't happened yet." Always implement proper error handling in prod!
Kudos to Cloudflare for the transparent postmortem 🦀
