Building the Async Python Task Queue I Wished Existed<\/a><\/h3>

If you’ve ever written async Python for your API and then switched to synchronous code for your background tasks, you know something is off. Repid v2 is an attempt to fix that - an async-first, AsyncAPI-native task queue built over two years of production use, countless rewrites, and one hand-written AMQP 1.0 implementation.

Inverse Sapir-Whorf and Programming Languages<\/a><\/h3>

The Sapir-Whorf hypothesis is the idea that the languages you speak influence the thoughts you can have. The inverse is the idea that your language limits what you can’t but say. When applied to programming this has subtle results determining core ideas like execution order.
