Why #define TRUE (1==1) in a C boolean macro instead of simply as 1?
...
This approach will use the actual boolean type (and resolve to true and false) if the compiler supports it. (specifically, C++)

Why do people say there is modulo bias when using a random number generator?
I have seen this question asked a lot but never seen a true concrete answer to it. So I am going to post one here which will hopefully help people understand why exactly there is "modulo bias" when using a random number generator, like rand() in C++.

How to check if an object is a list or tuple (but not string)?
This is what I normally do in order to ascertain that the input is a list / tuple - but not a str . Because many times I stumbled upon bugs where a function passes a str object by mistake, and the target function does for x in lst assuming that lst is actually a list or tuple .

Clang vs GCC - which produces faster binaries? [closed]
I'm currently using GCC, but I discovered Clang recently and I'm pondering switching. There is one deciding factor though - quality (speed, memory footprint, reliability) of binaries it produces - if gcc -O3 can produce a binary that runs 1% faster, or Clang binaries take up more memory or just fai...
