What's a good rate limiting algorithm?
...ard_message();
allowance -= 1.0;
There are no datastructures, timers etc. in this solution and it works cleanly :) To see this, 'allowance' grows at speed 5/8 units per seconds at most, i.e. at most five units per eight seconds. Every message that is forwarded deducts one unit, so you can't se...
C++ project organisation (with gtest, cmake and doxygen)
...nd TEST_F. Value- or Type-parameterised tests using TEST_P, TYPED_TEST_P, etc. aren't handled at all.
The problem doesn't have an easy solution that I know of. The most robust way to get a list of gtest cases is to execute the test exe with the flag --gtest_list_tests. However, this can only be ...
How to check whether an array is empty using PHP?
...easiest way to check if it's empty? I'm assuming I can do so as soon as I fetch the $gameresult array into $gamerow ? In this case it would probably be more efficient to skip exploding the $playerlist if it's empty, but for the sake of argument, how would I check if an array is empty as well?

What is Java String interning?

(How) can I count the items in an enum?
...ainerClass *m_containers[Folders_MAX + 1];
....
m_containers[FA] = ...; // etc.
Edit: Regarding { FA, FB, FC, Folders_MAX = FC} versus {FA, FB, FC, Folders_MAX]: I prefer setting the ...MAX value to the last legal value of the enum for a few reasons:
The constant's name is technically more accur...
What exactly are DLL files, and how do they work?
...e binary files that can contain executable code and resources like images, etc. Unlike applications, these cannot be directly executed, but an application will load them as and when they are required (or all at once during startup).
Are they important?
Most applications will load the DLL files the...

For HTML before HTML5 only: you want all data sent to you by browsers to be in UTF-8. Unfortunately, if you go by the only way to reliably do this is add the accept-charset attribute...
