Why does GCC generate such radically different assembly for nearly the same C code?
...fast_trunc_one() - register names and everything.
Notice that there are no xors in the assembly for fast_trunc_one(). That's what gave it away for me.
How so?
Step 1: sign = -sign
First, let's take a look at the sign variable. Since sign = i & 0x80000000;, there are only two possible values th...
What is the preferred Bash shebang?
...through 2018 /usr/bin/env exists on more machines than either of /bin/bash xor /usr/bin/bash, so a script that starts with this line will do the expected thing on as many machines as possible.

Using scanf() in C++ programs is faster than using cin?
...a simple case: a program to read a list of numbers from standard input and XOR all of the numbers.
iostream version:
#include <iostream>
int main(int argc, char **argv) {
int parity = 0;
int x;
while (std::cin >> x)
parity ^= x;

STL or Qt containers?
...ture, if need be.
The same is true of doubly linked lists, which could use XOr linking to drastically reduce space used. Again, this is impossible with Qt, due to it's requirements for growth and COW.
COW can indeed make something lighter, but so can Intrusive Containers, such as supported by boost,...

Why is a boolean 1 byte and not 1 bit of size?
... Not sure I would agree that bitwise operations are slow. ands, nots, xors etc are very fast. It is typically the implementation of the bitwise operations that are slow. At the machine level they are quite fast. Branching... now that is slow.
