Stash makes it easy to speed up your code by caching the results of expensive functions or code. Certain actions, like database queries or calls to external APIs, take a lot of time to run but tend to have the same results over short periods of time. This makes it much more efficient to store the results and call them back up later. Stash makes caching easy by providing a wrapper class in front of various backend storage handlers.
Chebfun is a collection of algorithms and a software system in object-oriented MATLAB that extends familiar powerful methods of numerical computation involving numbers to continuous or piecewise-continuous functions. It also implements continuous analogues of linear algebra notions like the QR decomposition and the SVD, and solves ordinary differential equations. The mathematical basis of the system combines tools of Chebyshev expansions, fast Fourier transform, barycentric interpolation, recursive zerofinding, and automatic differentiation.
csvgroupby is a small utility program that allows you to obtain aggregated statistical information from comma-separated files containing tabular data. It is similar to the SQL GROUP BY clause. It currently supports the COUNT, MAX, MIN, SUM, and AVG operators. It performs as many processing jobs as possible in a single run through the data file, which means that large data sets can be efficiently processed.
Java Gearman Service is a Java implementation of the gearman service, which provides a generic application framework that farms work out to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions in other languages. It can be used in a variety of applications, from high-availability Web sites to the transport of database replication events.
Raster is a library of raster image operations. Raster uses a graph method, where each node represents an operation. The root nodes of the graph are the resulting output images. Leaf nodes of the graph are sources of input data. Nodes in between represent operations on their children. Cycles in the graph must not be made.
PHPTracker is a PHP library to generate .torrent files, set up a Bittorrent tracker server, and a seed server too. It is capable of creating standard .torrent files from any file on your server, tracking client peers and managing peer announcements, and initially seeding your file with a peer daemon that automatically shuts down once you have enough external seeders.
The radierl project implements the RADIUS protocol, as decribed in RFC2865 and RFC2866, as a stack application in Erlang/OTP. It includes test suites, documentation, and an example application that implements basic athentication and accounting servers using mnesia and disk_log respectively.
