Quake 2 is a commercial 3D action game from id software, the makers of Doom. It is a shooter with a first-person perspective, in Doom's tradition. The game comes with three display methods. Anybody can run it on a virtual console (using SVGAlib) or under X. If you've got a 3D accelerator board based on the Voodoo chipset from 3dfx Quake 2 can use it to improve the display quality.

RenderDotC (RDC) is a photorealistic rendering toolkit which adheres to the RenderMan(R) standard. Using the Reyes architecture, RDC supports advanced capabilities such as motion blur, depth of field, trim curves, texture/environment/displacement mapping, and programmable shading in the RenderMan Shading Language. The shader compiler included in the toolkit compiles shaders all the way to machine language for the highest possible performance.
Rute (Rute Users Tutorial and Exposition) is a book on GNU/Linux that aims to be the definitive guide for new users as well as sufficing as training course material, covering both the RHCE and LPI requirements. It covers essential theory to UNIX as well as giving practical tutorials on all fundamental aspects of Unix administration, from basic commands, the theory of TCP/IP, the Linux filesystem, through to configuration of mail, DNS, and other servers, through hardware configuration and package management. It is not Unix-specific but tends to give examples suited to Debian and RedHat-like systems. Rute comes in HTML and PDF formats.
Saké Mail is a very high performance Web-based email system, designed for scaling to large numbers of concurrent users. It takes advantage of the Java Servlet API's memory-resident architecture and multi-threading HTTP response model. It avoids file system accesses through memory caching at every possible point, and never needs to touch the file system at runtime at all if coupled with an IMAP server. It supports POP3, IMAP, and SMTP, including authenticated SMTP. It also provides an extremely sophisticated message rendering system that can easily handle even complex HTML encoded messages with attachments that have been forwarded multiple times.
SecureNet PRO is a network monitoring and intrusion detection platform. It combines powerful scripting functionality with real-time session viewing and control capabilities. It goes beyond network-grep and signature-based intrusion detection offerings, offering a combination of true state-based decoding of application-layer protocol traffic and high-speed pattern matching. It offers full IP fragment reassembly functionality, TCP session reconstruction, and an advanced TCP/IP stack emulation facility.
