Spoink is an output plugin for snort that works by blocking access to attackers using OpenBSD's pf API. Spoink uses a pf table and a blocking rule to stop "attackers" from accessing your system. To protect from false negatives you must have a whitelist full of IP addresses. It only blocks attacks defined in snort rules.
Brabosphere is a program for the 3D visualization of molecular systems and their properties. Its name is derived from the quantum mechanical program package BRABO, for which it acts as a graphical frontend. It can also be used for the analysis and visualization of the data resulting from this type of calculation, so results from some other quantum mechanical applications will also be accepted.
LibJAD is collection of miscellaneous routines for a variety of purposes. This library includes functions of reading ini style files, multi-threaded programming, finding the number of processors available on the system, computing combinations and permutations, base64 and URL encoding, and working with ASN1 and PGM files.
NTW Lisp is a server written in Common Lisp for applications that use the NTW protocol to communicate with a GUI client. This asynchronous protocol makes it possible to serve remote applications that are indistinguishable from native ones. It's also useful for quickly writing GUI apps from Common Lisp that can be run locally.
The Zero Calorie DNS is a domain name server for which the binary weighs in at 26K, that has no dependencies other than the minimal FreeBSD 6.0 installation. The server responds to "name server" (NS), "start of authority" (SOA), "address record" (A), "reverse address" (PTR), and "mail exchanger" (MX) requests. The server is fairly fast because the feature set has been trimmed down to the bare minimum. A few things are hard-coded so that a two minute setup is easy to accomplish. The hard-coding means that it may not be for everyone, however.
