The CRT X-Y Library (libcrtxy) allows you to write vector-based video games (like Asteroids, Lunar Lander, and Battlezone from the 1970s and 80s). The end-user (and/or packager of your software) determines how lines are rendered, depending on the capabilities of their system. This choice includes anti-aliasing, alpha blending, blurring, and even the display size and depth. Fixed-point math is used, and sine and cosine trigonometric functions (using look-up tables) are provided. The library is based on libSDL and uses SDL as the video backend.
libmsocket is a socket abstraction library in C, which aims to support as many protocol abstractions transparently as possible. Current goals include SSL and Socks5 proxies. At its core, libmsocket makes developing socket applications very easy, even if you're not using any of those abstractions at all. It also ties in to libevent for I/O multiplexing and asynchronous DNS resolution.
libpwstor is a library implementing a password storage format for C programmers. This format provides a reasonable level of security by utilizing SHA-256 in addition to a random salt to mitigate dictionary and rainbow table attacks. In addition to the core functionality, libpwstor also offers some additional functions such as Base64 encoding and decoding. All functionality is implemented and designed in such a way as to be easy to use for C programmers of varying skill levels, while preserving reasonable security in the underlying storage format.
WMFS (Window Manager From Scratch) is a lightweight and highly configurable tiling window manager for X. It can be configured with a configuration file (made with LibConfuse), supports Xft (Freetype) fonts and is compliant with the Extended Window Manager Hints (EWMH) specifications.
The System Data Recorder has a collection part, or the part that handles recording the data from each system, and a reporting side where it permanently stores and generates simple reports and graphs. For some configurations, it can use only the recording part without the reporting side at all. The data recorder consists of many simple utilities developed in Korn and Perl that extract different telemetry from the Solaris kernel statistic module. Some recorders gather their data from various processes directly using OS or third party utilities. There are 5 recorders that should be installed and deployed in any system, and optional recorders needed only in certain cases: CMT and JVM.
