What is the difference between integration and unit tests?
...ence, when a unit test for a method implementing some feature is green, it does not mean the feature is working.
Say you have a method somewhere like this:
public SomeResults DoSomething(someInput) {
var someResult = [Do your job with someInput];
Log.TrackTheFactYouDidYourJob();
return someR...

Why is unsigned integer overflow defined behavior but signed integer overflow isn't?
...rently in that case).
It is also worth noting that "undefined behaviour" doesn't mean "doesn't work". It means that the implementation is allowed to do whatever it likes in that situation. This includes doing "the right thing" as well as "calling the police" or "crashing". Most compilers, when pos...
What is the fastest/most efficient way to find the highest set bit (msb) in an integer in C?
...ult for input=0 as 32 or 64 (according to the operand width). x86's lzcnt does that, too, while bsr produces a bit-index that the compiler has to flip unless you use 31-__builtin_clz(x).
(The "undefined result" is not C Undefined Behavior, just a value that isn't defined. It's actually whatever w...

Python: fastest way to create a list of n lists
...
is
from itertools import repeat
d = [[] for i in repeat(None, n)]
It does not have to create a new int object in every iteration and is about 15 % faster on my machine.
Edit: Using NumPy, you can avoid the Python loop using
d = numpy.empty((n, 0)).tolist()
but this is actually 2.5 times sl...

When should I use std::thread::detach?
..., it is advised not to join from a destructor. The problem is that joining does not end a thread, it merely waits for it to end, and unlike you have a signal in place to cause the thread to terminate you might be waiting for a long time... blocking the current thread whose stack is being unwound and...
Spinlock versus Semaphore
...hem at some far away time in the future.
A semaphore, by contrast, either does not spin at all, or only spins for a very short time (as an optimization to avoid the syscall overhead). If a semaphore cannot be acquired, it blocks, giving up CPU time to a different thread that is ready to run. This m...
