Topologic is a simple renderer for certain higher-dimensional geometric primitives and some regular 3D shapes. The idea is to make it easy for students of certain higher-dimensional maths and physics topics to visualize the typical primitives in those fields and get a grasp for the topic. Note: the program as such is freeware, while the part of it that deals with the Mathematics to project the geometric shapes to 3-space and 2-space has been released separately under an MIT/X style license.
OpenLaunch is a Web-based content management system that integrates a broad array of services into a single, fully-featured, elegantly designed Web site. The project aims to eliminte the difficulty of integrating multiple systems into a single Web site by implementing a blog, forum, Web pages, wiki, and (coming soon) E-Commerce and support tickets. It is built around the Torpedo Framework, an open MVC framework which includes support for controllers, forms, and a large number of other very useful utilities.
cso is an easy to use C module that serializes objects into a simple binary format. It can be used to store data or to send it over a network. It supports either an object of type struct (CSO_DICT) or array (CSO_ARRAY) which contains elements of type integer of different sizes, double, binary, string, struct, or array.
The libQtCassandra library is an advanced C++ library used to access Cassandra servers. Unlike the basic Cassadra server interface, this C++ library provides separate objects that handle each level of the server data, i.e. the cluster, contexts, table, rows, and cells. It uses Qt and the Qt style for all the classes, which makes it very easy to use if you already know Qt.
URL Router is a PHP class that can match URLs with routes for controllers and actions. It takes the definition of one or more routes with string expressions that define patterns to match given URLs. It supports a special route pattern syntax that allows defining how to extract the name of the controller and action from the URL. The class returns an array with the details of the matched route.
Gfarm is a distributed filesystem, generally used for large scale cluster computing. It's implemented in userland, and can be mounted by FUSE. It utilizes locality of a file to access a data node, and supports Globus GSI for Wide Area Network. Users can explicitly control file replica location on Gfarm. Gfarm can be used as an alternative storage system to HDFS for Hadoop, Samba, MPI-IO, and GridFTP. Monitoring via ZABBIX and Ganglia is also supported.
txtorcon is a Twisted-based asynchronous Tor control protocol implementation. Twisted is an event-driven networking engine written in Python, and Tor is an onion-routing network designed to improve people’s privacy and security on the Internet. It includes unit-tests with 96%+ coverage, multiple examples, and documentation. There are abstractions to track Tor configuration and state (circuits, streams), launch private instances, support Hidden Service, and more.
