neko-install-cd is a development tool for modifying System Rescue CD images. It can also perform many other operations. It has a simple interface with excellent inline help. Operations it can perform include: booting your modified image in a virtual machine, burning the original or modified image to a USB drive, creating patch sets from your modifications (using aufs or built-in helper scripts). All of these operations can be performed directly from your Linux distribution, without having to first boot into the system rescue CD as with the system rescue CD equivalents.
pgmp is a PostgreSQL extension module that adds support for the arbitrary precision data types offered by the GMP library. It provides higher performance arithmetic for numbers, only limited by the 1GB varlena maximum size, a rational data type for absolute precision storage and arithmetic, and specialized functions to deal with prime numbers, random numbers, and factorization. The GMP data types can be used in mixed arithmetic with other PostgreSQL numeric types and indexed using the btree or hash methods. The extension is compatible with PostgreSQL 8.4 and later, and the package includes comprehensive documentation and regression tests.
Quasi extracts code fragments from text documentation and appends them to new source code files. Unlike other literate programming tools, it does not perform any sort of macro expansion. The strength of Quasi is its simplicity - it forces the programmer to think in turns of properly designed methods.
dosbox-ipxrelay is a very simple, super-low-overhead dedicated server to support the DOSBOX version of IPX-over-UDP for old games. In particular, when left completely idle, it should consume no CPU time whatsoever. It should also have substantially better latency than the DOSBOX built-in server. It was designed and tested on Linux, and it should compile on any modern POSIX-compliant system.
PHDoc is a version of Markdoc adapted to the needs of academics. It aims to provide a lightweight alternative to large database-powered wiki systems, giving easy management of Web sites with a clean typographic layout, inspired by the beauty of LaTeX-made documents. LaTeX math markup and automatic hyphenation are supported. Scaffolding exemplifies everything that is needed for a personal website, without any technical prerequisites like HTML or CSS.
ACOPOST is a set of freely available POS taggers modeled after well-known techniques. The programs are written in C (aiming for extreme portability and code correctness/safety) and run under various Unix flavors (and probably even under Windows). ACOPOST currently consists of four taggers that are based on different frameworks: Maximum Entropy Tagger (MET), Trigram Tagger (T3, based on Hidden Markov Models), Error-driven Transformation-based Tagger (TBT or Brill Tagger), and Example-based tagger (ET).
