Stories, tutorials, and deep dives spanning across diverse worlds.
The definitive production reference for Python asynchronous programming: event loop internals, structured concurrency with TaskGroup, free-threaded CPython 3.13, connection pooling, and profiling event loop starvation.
Master Python asyncio in 2026: Coroutines, TaskGroup vs gather, uvloop internals, preventing event loop starvation, and async semaphore pooling.
Why 4 threads can make CPU code 50% slower. Compare AsyncIO event loops, GIL workarounds, and multiprocessing benchmarks with architectural decision trees.
Master advanced Go concurrency patterns: goroutine worker pools, channel fan-in/fan-out, context cancellation, and race condition prevention strategies.
Audit C extensions, eliminate GIL assumptions, and safely migrate multi-threaded Python workloads to free-threaded CPython 3.13+ for true parallelism.
