How to generate a random int in C?
...
+1 for simplicity, but it is probably a good idea to emphasize that srand() should only be called once. Also, in a threaded application, you might want to make sure that the generator's state is stored per thread, and seed the generator once for each thread.

Check if a string is html or not
...) {
if (c[i].nodeType == 1) return true;
}

Return all enumerables with yield return at once; without looping through
...ollection must be created per call, returning a collection is a really bad idea.
Most collections can be modified when returned.

What does “DAMP not DRY” mean when talking about unit tests?
...ningful Phrases.
"DAMP not DRY" values readability over code re-use. The idea of DAMP not DRY in test cases is that tests should be easy to understand, even if that means test cases sometimes have repeated code.

How to send an object from one Android Activity to another using Intents?
