Why does this code using random strings print “hello world”?
...
I'll just leave it here. Whoever has a lot of (CPU) time to spare, feel free to experiment :) Also, if you have mastered some fork-join-fu to make this thing burn all CPU cores (just threads are boring, right?), please share your code. I would greatly appreciate it.

Why are C character literals ints instead of chars?
...A' from this main memory into a register, which one would you read?
Some CPUs may only directly support reading a 16 bit value into a 16 bit register, which would mean a read at 20 or 22 would then require the bits from 'X' be cleared out, and depending on the endianness of the CPU one or other wo...

Try using more partitions, you should have 2 - 4 per CPU. IME increasing the number of partitions is often the easiest way to make a program more stable (and often faster). For huge amounts of data you may need way more than 4 per CPU, I've had to use 8000 partitions in some c...

Concurrent.futures vs Multiprocessing in Python 3
...ay eventually frustrate you in ways the richer interfaces won't.
So far as CPU-bound tasks go, that's way too under-specified to say much meaningful. For CPU-bound tasks under CPython, you need multiple processes rather than multiple threads to have any chance of getting a speedup. But how much (i...
recursion versus iteration
... course every recursion can be modeled as a kind of loop : that's what the CPU will ultimately do. And the recursion itself, more directly, means putting the function calls and scopes in a stack. But changing your recursive algorithm to a looping one might need a lot of work and make your code less ...
