The Real Cost of Drop-in Compatibility: What I Threw Away Porting markdownlint-cli2 to Rust
I ported markdownlint-cli2 to Rust and matched 264,114 diagnostics on this blog repository byte for byte. The commits that ported 51 rules landed in a single day, but turning that into a tool you could actually swap in took two weeks. A record of giving up a parser 37 times faster, correcting two performance misreadings, and finding 11 more compatibility differences in an adversarial review.

What Happens When You Install typescript@7: A Blog Monorepo Migration Log
I dropped typescript 7.0.2 into a monorepo where pnpm lint took 12 minutes 32 seconds. Type checking passed quietly, but next build broke and lint crashed. A record of the chain reaction from one day of swapping eslint and prettier for oxlint and oxfmt, with before-and-after measurements. To say it up front, the build did not get any faster.
