Why should I not include cpp files and instead use a header?
...would've got from separating your source files in the first place.

Node.js vs .Net performance
...FAST and handling lots of LOAD are two different things. A server that's really FAST at serving one request per second might totally croak if you send it 500 requests per second (under LOAD).
You also have to consider static (and cached) vs dynamic pages. If you're worried about static pages, then...
deciding among subprocess, multiprocessing, and thread in Python?
I'd like to parallelize my Python program so that it can make use of multiple processors on the machine that it runs on. My parallelization is very simple, in that all the parallel "threads" of the program are independent and write their output to separate files. I don't need the threads to exchan...
How to pass objects to functions in C++?
...ne whether to pass by const reference or not.)
Passing by pointer is virtually never advised. Optional parameters are best expressed as a std::optional (boost::optional for older std libs), and aliasing is done fine by reference.

Is R's apply family more than syntactic sugar?

Edit 2:
Regarding the usage of parallel packages for R (e.g. rpvm, rmpi, snow), these do generally provide apply family functions (even the foreach package is essentially equivalent, despite the name). Here's a simple example of the sapply function in snow:

Why is lazy evaluation useful?
...epending on the sequence of conditional expressions, only a subset may actually be used. In a language like C, all three values would be computed anyway; but in Haskell, only the necessary values are computed.
It also allows for cool stuff like infinite lists. I can't have an infinite list in a lan...
