re2js just got a lot faster at boolean matching. 🚀 I stripped out the overhead so matches() hits the DFA fast-path directly. Also added test() and testExact() for zero-allocation matching that bails on ReDoS traps instantly (no slow exceptions). re2js.leopard.in.ua/ #redos

Just updated PGTune. The math was showing its age, so it now supports PostgreSQL 18's new Async I/O, NVMe storage profiles, and scales memory limits based on whether your DB actually fits in RAM. Check it out: pgtune.leopard.in.ua/ #postgresql #pgtune #tunning #database

"Active development [of jemalloc] has come to an end" - Jason Evans
This doesn't really change my usage of jemalloc in the short term (the current release is 3 years old and works great). But in 1-3 years we'll probably have a different/better allocator option for Ruby.

Google, Azure, Twitter, Facebook, Heroku Oauth - just use it, allow to use API, no billing required
Shopify Oauth - billing API required and plan per Shopify shop (even if you don't need to be in their marketplace)
Worst requirements ever for integration
