Actually, it is implementable without having to much CPU load (I think. I haven't been testing it). On dom ready build the <a> elements with javascript, take the mouse postion and then remove all <a> elements. On mousemouse you should have other function to take the...

Why is Swift compile time so slow?
...thing to note is that, by default, it builds 2 files concurrently per each CPU core, and will not give you the "net" elapsed time, but the absolute "user" time. This way all the timings even out between parallelized files and look very similar.
To overcome this, set the -jobs flag to 1, so that it ...

What is the purpose of the “final” keyword in C++11 for functions?
...s is that for any such virtual object (assuming 64-bits on a typical Intel CPU) the pointer alone eats up 25% (8 of 64 bytes) of a cache line. In the kind of applications I enjoy to write, this hurts very badly. (And from my experience it is the #1 argument against C++ from a purist performance poin...
What's the purpose of the LEA instruction?
