Removing trailing newline character from fgets() input
...trimming is usually not an issue given code is doing I/O - a black hole of CPU time. Should following code need the string's length or is highly performance conscious, use this strlen() approach. Else the strcspn() is a fine alternative.

Why does integer overflow on x86 with GCC cause an infinite loop?
...y integers wrap around, but on occasion weird stuff happens".
Yes, on x86 CPUs, integers usually wrap the way you expect. This is one of those exceptions. The compiler assumes you won't cause undefined behavior, and optimizes away the loop test. If you really want wraparound, pass -fwrapv to g++ or...

Why are primes important in cryptography?
... @stujo: same principles will rule when all of us use Quantum CPUs, as primes can keep growing, its all about finding larger, impractical for quantum CPUs, the problem exists if some use regular CPUS to create keys, and some use Quantum CPUs to break those. The power of quantum CPUs, as...
Best way to check if object exists in Entity Framework?
...housands of database calls were being made to check for duplicates (so the CPU sent a lot of time at 100%). In the end I decided to keep the last 100,000 records cached in memory. This way I could check for duplicates against the cached records which was extremely fast when compared to a LINQ quer...
Java logical operator short-circuiting

Note that this is more than an attempt at saving a few CPU cycles: in expressions like this

short-circuiting means a difference between correct operation and a crash (in the case where mystring is null)....
