Previously, fiction books published on the Web were often divided into lines of ~80 characters for comfortable reading. This can be a problem on small displays (such as phones), causing poorly-wrapped formatting. Reformator is a simple Qt utility that attempts to remove newlines inside paragraphs without removing those between paragraphs. Just set the size of the first line indent, and Reformator will recognize real paragraphs and remove all non-useful newlines. It can also detect indent size automatically. It is recommended to back up your books before reformatting.
Libfbm is a C++ library for fast and accurate bulk-simulation of multi-dimensional (1D, 2D, 3D, .., 8D) Gaussian stationary processes, fractional Brownian motion, and fields with power-law power spectrum. It makes use of the circulant matrix embedding and FFT. Random number generation is provided by SFMT (SIMD-optimized Mersenne Twister) with a ziggurat based algorithm for normal distribution. For FFT functions, it depends on the FFTW library.
