When should I use the “strictfp” keyword in java?
...lations need to be deterministic no matter what the underlying hardware or CPU is. What's the trade-off? Most likely execution time.

What is the easiest way to remove the first character from a string?

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...

NSOperation vs Grand Central Dispatch
...down of these NSOperations was accounting for a significant portion of the CPU cycles in the running application, and was slowing things down. I replaced these with simple blocks and a GCD serial queue, and that overhead disappeared, leading to noticeably better rendering performance. This wasn't th...
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.

Async/Await vs Threads
...
Worth mentioning await Task.Run for cpu-bound work. If I understand correctly, that sometimes accomplishes what one would otherwise create a thread, or a background worker, to do.

What is Turing Complete?
... together to allow for all of those nice things that you mention. E.g. the CPU produces "tape" for the GPU to read so that it can write "tape" for the monitor so that the monitor can write "tape" to the user. Likewise, the CPU could produce "tape" for the hard drives, NICs, sound cards, etc.

How are everyday machines programmed?
...have 8 or 16 pins on the chip - compared to scores of pins in your regular CPU socket.
So the workflow is write some code (say, in C), compile it on your desktop machine. That compiler generates machine code for the embedded chip. Then that code is loaded onto the microprocessor (and you need speci...
