Here's a thrilling odyssey of a C/C++/Rust acolyte discovering that Haskell—yes, 
#HASKELL —can do concurrency! Who knew that "self-indulgent academic baloney" could also be "fast, simple, correct"? 
Get ready for groundbreaking insights that will inevitably make you reconsider every life choice you've ever made about #concurrency.

Just published a longform article on parallel collectors in Java Streams.
Covers correctness, performance, pitfalls
Custom collectors with CONCURRENT semantics

TL;DR: .parallelStream() is not a magic wand.
Concurrency and parallelism are often confused in async programming discussions. Go's goroutines highlighted the difference: concurrency is doing many things at once, while parallelism is doing many things at the same time.
AsyncIO handles concurrency well for I/O, but CPU-bound tasks need parallelism. Python uses AsyncIO for concurrency, and ProcessPoolExecutor for parallelism, distributing work across CPU cores.
Process communication is harder than thread communication. AsyncIO's task cancellation differs from ProcessPoolExecutor's, requiring workarounds like event objects for reliable cancellation and shutdown.
Essentially, ProcessPoolExecutor enables parallelism for CPU-bound tasks, scaling them across multiple cores, while AsyncIO handles I/O concurrently.

Interesting, I've wrapped some code in `Task { @MainActor in /* code */ }` because I wanted to hide the concurrency warning, and now my app is way faster. I've no idea how, but I'm happy that this is the effect

Finally got the mpb progress bar with #goroutines and goroutine limiting to work properly.
Python and concurrency are a pain. I'm trying to read the Raspberry Pi camera and send mouse coordinates via USB.
If I try to send mouse coordinates via USB in the same thread, it slows the raspberry pi camera FPS from 70 -> 40. Same problem if I try to use different threads via 'threading', 'asyncio' or 'multiprocessing' API.
It works fine if I run two completely separate Python scripts. 75 fps, and 100 fps in mouse script.
Maddening!
