require anywhere from a small number

The ability of the interpreter to deduce type and type conversions makes development time faster, but it also can provoke runtime failures which you just cannot get in a statically typed language where you catch them at compile time. But which ...
How can we match a^n b^n with Java regex?
...his answer will guide readers through the process of deriving it. Various hints are given as the solution is slowly constructed. In this aspect, hopefully this answer will contain much more than just another neat regex pattern. Hopefully readers will also learn how to "think in regex", and how to pu...
Why does Windows64 use a different calling convention from all other OSes on x86-64?
...fix byte to select them and therefore have a bigger instruction size footprint, so you wouldn't want to choose any of those if you have options.

return $a->baz - $b->baz;
}
Functions
