crypt++.el is a package of Lisp functions that recognize automatically encrypted and encoded (i.e., compressed) files when they are first visited or written. The BUFFER corresponding to the file is decoded and/or decrypted before it is presented to the user. The file itself is unchanged on the disk. When the buffer is subsequently saved to disk, a hook function re-encodes the buffer before the actual disk write takes place.
ctGUI is the window system abstraction and associated widget sets in the Coral Tree Library Set. The window system abstraction currently supports X/OpenGL, X/Xlib, Win32/OpenGL, and Win32/GDI (window & event system/drawing mechanism). ctGUI (aka LEWDS and EW/WDS/IWS) provides yet another approach in addition to the approaches taken by Qt, gtk, MFC, etc.
CwMtx is a library written in C++ that provides the matrix and vector operations that are used extensively in engineering and science problems. A special feature of this library is the quaternion class which implements quaternion math. Quaternions are very useful for attitude determination in 3D space because they do not suffer from singularities. Furthermore, successive rotations and transformations of vectors can be accomplished by simple quaternion multiplication. Attitude dynamics can be expressed in a very compact form using quaternions
cxmon is an interactive command-driven file manipulation tool inspired by the "Amiga Monitor" by Timo Rossi. It has commands and features similar to a machine code monitor/debugger, but it lacks any functions for running/tracing code. There are, however, built-in PowerPC, 680x0, 80x86, 6502 and Z80 disassemblers and special support for disassembling MacOS code. cxmon is primarily intended for emulation development but it can be used as a generic tool for manipulating and analyzing binary data and machine code, or just as a hex calculator.
DarkFire IRCd is an efficient, modern, and flexible IRC server used primarily on the DarkFire IRC Network. Originally based on Dreamforge, it has numerous enhancements and a wider variety of features. It features an efficient server to server protocol, a wide variety of user and operator commands, and a flexible protocol.
