Why is processing a sorted array faster than processing an unsorted array?
...sn't able to optimize the branch into a conditional move, you can try some hacks if you are willing to sacrifice readability for performance.
Replace:
if (data[c] >= 128)
sum += data[c];
with:
int t = (data[c] - 128) >> 31;

This eliminates the branch and repla...

This "hack" allows to launch of a reactor build from the root after a checkout and make things even more handy. Actually, this is how I like to setup maven projects and a VCS repository for large builds: it just works, it scales we...
What is the difference between LR, SLR, and LALR parsers?
...sing GLR means I can relatively easily build working grammars, compared to hacking a grammar to get into LALR usable form. This matters a lot when trying to deal to non-academic langauges such as C++ or Fortran, where you literally needs thousands of rules to handle the entire language well, and yo...

..., with the exception of IE6/7, where display:inline; zoom:1 is a fall-back hack for the broken support for inline-block.
display:inline-block;
This is my favourite option. It works well and consistently across all browsers, with a caveat for IE6/7, which support it for some elements. But see above f...

[1, 2, 0, 3]
Just one simple library import and no hacks.
This comes from an implementation of the itertools recipe unique_everseen which looks like:
