Why does comparing strings using either '==' or 'is' sometimes produce a different result?
...orks interactively is that (most) string literals are interned by default. From Wikipedia:
Interned strings speed up string
comparisons, which are sometimes a
performance bottleneck in applications
(such as compilers and dynamic
programming language runtimes) that
rely heavily on hash ...
Should I return a Collection or a Stream?
...likely to use the answer.
First, note that you can always get a Collection from a Stream, and vice versa:

Then, we swap t and t2. Swap operations should be nothrow in C++, so let's hope the swap you ...

How does the bitwise complement operator (~ tilde) work?
...peration is a complement, not a negation.
Consider that ~0 = -1, and work from there.
The algorithm for negation is, "complement, increment".
Did you know? There is also "one's complement" where the inverse numbers are symmetrical, and it has both a 0 and a -0.
