Footguns with Postgres “at time zone 'UTC'”
And why you may need to repeat AT TIME ZONE 'UTC' twice. SUMMARY * AT TIME ZONE 'UTC' converts the data type from timestamptz to timestamp (example). * Now you are inadvertently using the timestamp without time zone (aka timestamp) data type, which is markedly discouraged. * There are tons of footguns with timestamp…

JIT-optimized Ruby can outperform a C extension
YJIT’s ability to improve performance by adapting to run-time behavior can increase the speed of our code in a way that dropping down to C can’t. As such, I think we should reconsider the common wisdom that “rewriting our Ruby in C” is the ideal path to performance optimization and take a serious look at “rewriting…

It looks at how its focus on minification led to very different design choices than TypeScript, and how this and a few other factors led to TypeScript becoming the ubiquitous solution for JavaScript + types. The…
