Using Node.js only vs. using Node.js with Apache/Nginx
...tatic files as so many (every?) competing technologies (PHP, Ruby, Python, etc) require a web server like HTTPD or Nginx in front of the application server(s).

How to make an array of arrays in Java
...onality (index-based lookup, sorting, uniqueness, FIFO-access, concurrency etc.).
While it's of course good and important to know about Arrays and their usage, in most cases using Collections makes APIs a lot more manageable (which is why new libraries like Google Guava hardly use Arrays at all).

Why is std::map implemented as a red-black tree?
...these trees require that nodes carry information on height, weight, color, etc. Only Splay trees are free from such additional info. But most people are afraid of Splay trees, because of the ramdomness of their structure!

How does C compute sin() and other math functions?
...at book, you can decide if you have a hardware adder, multiplier, divider, etc, and decide which operations are fastest. e.g. If you had a really fast divider, the fastest way to calculate sine might be P1(x)/P2(x) where P1, P2 are Chebyshev polynomials. Without the fast divider, it might be just P(...
