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.
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.
Libcwd is a full-featured and well-documented library that assists C++ developers with debugging their applications. It includes support for ostream-based debug output, custom debug channels and devices, memory allocation debugging, run-time sourcefile:linenumber information, and demangled type names of variables. It is thread-safe.
Cassandra is a scientific data viewer based on VTK. Cassandra provides dynamic interaction with the VTK pipeline and enables the user to load plug-ins dynamically in order to perform specific tasks in data manipulation and visualisation. Cassandra is open and modular, and can easily be extended to new filters through a set of dynamically loadable plug-ins. A plug-in template is provided to help users to develop and share their own plug-ins. This approach allows users to perform complex filtering without any specific knowledge of VTK or C++.
Cervisia is a KDE graphical frontend for the CVS client. It features checking out a module from a repository, updating or retrieving the status of a working directory or single files, common operations like add, remove and commit, diff against the repository and between different revisions, annotated view of a file, view of the log messages in tree and list form as well as resolving of conflicts in a file.
Eckbox is van Eck Phreaking tool that interprets a radio signal emanating from a computer's monitor to recreate the image (in black and white) that is displayed on it. It could be used as a valuable security tool for testing otherwise secure computers or for developing hardware and software to counter this type of remote shoulder-surfing. It is not intended to be used for illegal purposes, and includes information on the hardware required.
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.
