The ServerUsage system collects and processes statistical information from computers running a GNU/Linux Operating System. It is composed of two subprojects, the ServerUsage-Client to collect usage statistics (via a SystemTap module) and send them to a remote server via TCP, and the ServerUsage-Server to collect all statistics from different clients and aggregate them in a SQlite database table. A PHP Web service is available on the server module to extract information or display graphics.
CloudBuddy Analytics is a Web-based tool that generates exhaustive statistical reports about your S3 bucket access. It has an intuitive interface for a rich user experience and takes care of enabling logging, fetching logs and generating reports. It can be configured for multiple S3 accounts, uses the AWStats engine, employs caching for faster reports, and gives details on bandwidth usage, visits, unique visitors, visit durations, last visits, days of week and rush hours (pages, hits, KB for each hour and day of week), domains/countries of visitors, and more.
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.
