OpenSC provides a set of libraries and utilities to work with smart cards. Its main focus is on cards that support cryptographic operations, and facilitates their use in security applications such as authentication, mail encryption, and digital signatures. OpenSC implements the PKCS#11 API so that applications supporting this API (such as Mozilla Firefox and Thunderbird) can use it. On the card, OpenSC implements the PKCS#15 standard, and aims to be compatible with every software/card that does so.
SWFTools is a collection of code for handling Flash .SWF-files. This includes a merging tool (swfcombine), an extracting tool (swfextract), PDF/JPEG/PNG/AVI/TTF/WAV to SWF converters (pdf2swf, jpeg2swf, png2swf, avi2swf, font2swf, and wav2swf), a text parsing tool (swfstrings), an SWF parser (swfdump), and a library for writing and reading SWFs (rfxswflib).
CLIP is a Clipper/XBase compatible compiler with initial support other xBase dialects. It features support for international languages and character sets. It also features OOP, a multiplatform GUI based on GTK/GTKextra, all SIX/Comix features (including hypertext indexing), SQL and ODBC drivers, a C-API for third-party developers, a few wrappers for popular libraries (such as BZIP, GZIP, GD, Crypto, and Fcgi), a multitasking client and application server based on TCP/IP sockets, object data base utilities, and a functions library.
Java Memory Profiler (JMP) uses the JVMPI interface to track objects and method times in the JVM (Java Virtual Machine). It uses a GTK+ interface to display statistics. The current instance count and the total amount of memory for each class is shown as is the total time spent in each method.
PhysicsFS is a library to provide abstract access to various archives. The programmer defines a "write directory" on the physical filesystem. No file writing done through the PhysicsFS API can leave that write directory, for security. For file reading, the programmer lists directories and archives that form a "search path". Once the search path is defined, it becomes a single, transparent, hierarchical filesystem. This makes for easy access to ZIP files in the same way as you access a file directly on the disk, and it makes it easy to ship a new archive that will override a previous archive on a per-file basis. Symbolic links can be disabled, for added safety. Finally, PhysicsFS gives you a platform- abstracted means to determine if CD-ROMs are available, the user's home directory, where in the real filesystem your program is running, etc.
Distributed Checksum Clearinghouse (DCC) is a system of clients and servers that collect and count checksums related to mail messages. The counts can be used by SMTP servers and mail user agents to detect and reject bulk mail. DCC servers can exchange common checksums. The checksums include values that are "fuzzy", or constant across common variations in bulk messages.
IRC Channel Relay Bot allows you to have an IRC channel span multiple IRC networks. It relays public and private messages, informs you about people joining and leaving the channel, and passes topics across networks (if you op it). It has minimal ability to help protect the channel.
GPLIGC is a program for analyzing IGC flight data from GNSS flight data recorders used by glider pilots. It uses Perl/Tk and gnuplot. The openGLIGCexplorer (written in C++) allows one to view the data in 3D with OpenGL, and can also be used as a digital elevation model terrain viewer. It can also be used for off-screen rendering of 2D and 3D images of flight tracks or terrain/map data.
