Polymorphism in C++
... a .size() member you'll use one function, otherwise another function that doesn't need .size() (but presumably suffers in some way - e.g. using the slower strlen() or not printing as useful a message in the log). You can also specify ad-hoc behaviours when the template is instantiated with specifi...

How do I achieve the theoretical maximum of 4 FLOPs per cycle?
...mperatures!!!Make sure you don't overheat it. And make sure CPU-throttling doesn't affect your results!
Furthermore, I take no responsibility for whatever damage that may result from running this code.
Notes:
This code is optimized for x64. x86 doesn't have enough registers for this to compile w...
Where and why do I have to put the “template” and “typename” keywords?
...s that:
t * f;
How should this be parsed? For many languages a compiler doesn't need to know the meaning of a name in order to parse and basically know what action a line of code does. In C++, the above however can yield vastly different interpretations depending on what t means. If it's a type, ...

Does this approach fail to work on the 24-bit example(3rd)? I'm not quite familiar with C and bitwise operators but from your explanation of the approach I'm guessing 24->12->6->3(3 bits uneven to split). As numBit...

Why is it slower to iterate over a small string than a small list?

You can check that this does seem to make a difference:

What is the purpose of Flask's context stacks?
