EarthLink SIPshare, a simple, SIP-based proof-of-concept content sharing application, demonstrates the viability of SIP as a protocol over which peer-to-peer (P2P) applications other than the well-known voice and video cases may be implemented.
framework for secure peer-to-peer networking that does not use any centralized or otherwise trusted services. A first service implemented on top of the networking layer allows anonymous censorship-resistant file-sharing.
parser attempts to conform, as much as possible, to the DOM Level 1 specification. Being written in JavaScript, it lacks some fundamental abilities found in other parsers, like loading XML data from a file or validating from a DTD.
a product that allows an organization HPC grid to be extended through aggregation of unused computing resources. For instance, ComputeMode allows a virtual cluster to be built using an organization's employees' PCs.
protocol intended for use in networked roleplaying games, and provides a flexible and extensible means of communicating between the components of a game system. The protocol is transport independant, encoding independant and portable.
The art of guessing results and solving problems without doing a proof or an exact calculation. Techniques include extreme-cases reasoning, dimensional analysis, successive approximation, discretization, generalization, and pictorial analysis. Application to mental calculation, solid geometry, musical intervals, logarithms, integration, infinite series, solitaire, and differential equations.
A GNU-FDL book on algorithmic graph theory by David Joyner, Minh Van Nguyen, and Nathann Cohen. This is an introductory book on algorithmic graph theory. Theory and algorithms are illustrated using the Sage open source mathematics software.
a cross-platform application to download and convert videos from your hard drive or from dozens of video sharing websites like YouTube, Dailymotion, Veoh, Metacafe, etc.
a program that analyzes Python programs and detects various errors. It works by parsing the source file rather than importing it, so it is safe to use on modules with side effects. It's also much faster.
