A Simple Version Control System is an easy to install and easy to to use version/revision control system. It differs from most other version control systems in that it is designed to keep track of files in place. It does not allow any changes to be made to files; all changes require the users to change files externally with FTP or SSH access. It is very easy to set up and use. Users do not need to work with repository, branches, commit, and check-out files. All a user needs to do is upload the changes files and click Update, or if enabled, just wait for it to be updated automatically.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
Hedgehog is a very concise implementation of a Lisp-like language for low-end and embedded devices. It consists of a compiler and a byte code interpreter. The Lisp dialect has proper support for local and lambda functions, lexical scoping, variable argument functions, garbage collection, exceptions, macros, and over a hundred predefined functions or special forms. The built-in types are lists, symbols, strings, 32-bit integers, AVL trees, and tuples up to 16 elements wide.
LDPC-codes is a collection of programs and modules intended to support research and education concerning Low Density Parity Check (LDPC) codes. The decoding algorithm for LDPC codes is related to that used for Turbo codes, and to probabilistic inference methods used in other fields. Variations on LDPC and Turbo codes are currently the best practical codes known, in terms of their ability to transmit data at rates approaching channel capacity with very low error probability.
LayManSys is an RDF-based PHP framework for generating a consistent layout for Web documents. It includes a library that can be used online as well as on the command line. It generates the headers and footers for HTML documents, manages (CSS) style definitions, shortcut icons (favicons), static HTML, and dynamic PHP content, and much more. The necessary meta information is either stored in RDF files or in special layout configuration files.
