In other words, a computer science student cannot assume that an associative array is ordered. The same is true for sets in math
the order in which the elements of a set are listed is irrelevant

How to generate a random number in C++?
... and from what generator and
in what galaxy it was requested. That is what word "random" means
after all - being unpredictable and independent of anything -
otherwise it is not random anymore, right? With this intuition it is
only natural to search the web for some magic spells to cast to get
such r...

Benchmarking
On the web we rarely find (if ever) a well-engineered benchmark. Until today I only found benchmarks that were done the journalist way (pretty quic...
Where does Scala look for implicits?
... because the question never seems to get fully formed, as if there weren't words for it. :-) For example, where do the values for integral below come from?

Why is x86 ugly? Why is it considered inferior when compared to others? [closed]
...ittle choice but to do some amount of bashing given the way the question's worded. But with the exception of (1), all these things were done for good reasons (see comments).

struct test{
void f() &{ s...
Fundamental difference between Hashing and Encryption algorithms
...but can't store the plain representation (for any number of reasons). Passwords should fit this use-case very well since you don't want to store them plain-text for security reasons (and shouldn't). But what if you wanted to check a filesystem for pirated music files? It would be impractical to s...
