deal.II is a C++ library supporting the generation of complex adaptive finite element codes. It features locally-refined grids, various scalar and vector-valued finite elements, linear solvers of low and higher order, arbitrary mappings, and support for 1, 2, and 3D computations. It comes with extensive documentation and example programs showing the use of the library for modern finite element programs.
Biblos is a powerful indexing tool that can manage your CD/MP3 collection as well as local directories. It records full information about each file on the specified media, and has a powerful searching tool that can help you find specific files. You can select from the database a list of files/directories, and it will help you copy them from the source media to the chosen directory.
Gangplank is a Computer Mediated Communication (CMC) system (or "chat server") which supports real-time communication between users, currently using a text-based user interface. It runs as an Internet server which implements the standard telnet protocol, so no special client program is necessary for users. Server-side processing provides input editing/history and terminal- handling features over the telnet connection for standard ANSI terminals. This code has been in production use on a private server since early 1993. This single-process server is fast, efficient and stable.
APD is a general purpose non-interactive PHP profiler/debugger that produces formatted strace/truss type reports. APD supports full stack backtraces via calls similar to croak() in Perl's carp. APD is a Zend Extension and is designed to provide timing with the minimal performance impact. APD supports varying levels of debugging and can be turned on/off in individual scripts.
