How do you pick a programming language, to learn or to use for a project? This article probably overlaps a lot with what others have already said on this topic . But I try to add a categorization of programming languages that reflects the way they are discussed on blogs and discussion sites. I think these categories are often implicit in discussions on the programming sub-reddit, Hacker News, or Lambda the Ultimate, but never made explicit for the benefit of younger developers. Each section describes languages in a category, how they are similar, and what distinguishes them from each other, along with a little history.

Motivation A perfect hash function maps a static set of n keys into a set of m integer numbers without collisions, where m is greater than or equal to n. If m is equal to n, the function is called minimal. Minimal perfect hash functions are widely used for memory efficient storage and fast retrieval of items from static sets, such as words in natural languages, reserved words in programming languages or interactive systems, universal resource locations (URLs) in Web search engines, or item sets in data mining techniques. Therefore, there are applications for minimal perfect hash functions in information retrieval systems, database systems, language translation systems, electronic commerce systems, compilers, operating systems, among others. The use of minimal perfect hash functions is, until now, restricted to scenarios where the set of keys being hashed is small, because of the limitations of current algorithms.

__inline BOOL SearchOneDirectory( IN LPSTR Directory, IN LPSTR FileToFind, IN LPSTR SourceFullName, IN LPSTR SourceFilePart, OUT PBOOL FoundInTree ) { // // This was way too slow. Just say we didn't find the file. // *FoundInTree = FALSE; return(TRUE); } [Vilhelm S. comments: Note that provides an offsetof(type, field_name) macro, so you can leave the dirty work of abusing NULL pointers in perverted ways to your standard library implementor! (The typical implementation of it is as above, though...)]

FFTW Home Page
Introduction FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). We believe that FFTW, which is free software , should become the FFT library of choice for most applications. The latest official release of FFTW is version 3.3.1 , available from our download page . Version 3.3 introduces support for the AVX x86 extensions, a distributed-memory implementation on top of MPI, and a Fortran 2003 API.
