PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension.
WordPress is a state-of-the-art, semantic, personal publishing platform with a focus on aesthetics, Web standards, and usability. It was born out of a desire for an elegant, well-architected personal publishing system. While primarily geared towards functioning as a Weblog, WordPress is also a flexible CMS capable of managing many types of Web sites. In addition to the basic blog functions, it also has an integrated link manager, categories, tags, custom taxonomies, file attachments, XFN support, support for stand-alone pages, Atom and RSS feeds for both content and comments, blogging API support (Atom Publishing Protocol, Blogger, MetaWeblog, and Movable Type APIs), spam blocking features, advanced cruft-free URL generation, a flexible theme system, and an advanced plugin API.
Dictconv-cx is a dictionary converter that is a stripped down and expanded version of dictconv. It removes support for the DICT dictionary, stardict, as other tools such as makedict handle it well, and adds support for UTF-8 encoding, keywords longer than 255 characters, 82,000+ character length in definitions, and other changes.
mkESA is a program for constructing enhanced suffix arrays (ESAs) from biological sequence data. The program is based on an implementation of Manzini's lightweight Deep-Shallow algorithm, which can also utilize multiple CPUs/cores for extra performance. The generated output is compatible with the output of mkvtree from the Vmatch package.
Cgictrl is a CGI framework for Ruby. It allows you to use the structure of a mainframe program (like on IBM's CICS) with CGI. Programs are selected by transaction codes, and the CGI program indicates the next transaction code to continue the conversation process. Basically, one CGI program sends only one kind of view, and processes input data from only this view. Each program can store internal data in a SPA (Scratch Pad Area) on the server, which is allocated uniquely per session.
