Mover is a system designed to move mail while eliminating as much metadata as possible. In fact, it eliminates virtually all metadata, except for the order and possibly the time that a message arrives at a given site. Addresses are encryption keys. The encrypted messages are sent to all mover locations. The intended recipient uses their key to decrypt the message.
MathMod is mathematical software for visualizing and animating parametric and implicit surfaces. It is an extension/rewrite of the K3DSurf project. It supports 3D/4D plotting and animation, a scripting language, a JSON file format with a large set of scripted examples, and an OBJ output file of the 3D mesh.
Qmonix is a quantitative software monitoring and analysis SDK. It allows you to build your own analytics infrastructure by monitoring and analyzing events from any platform that supports HTTP, visualize your data in real time in the provided Web interface or query with the HTTP API, embed charts in your Web sites, or export data for further analysis.
Synth is a C++ template framework - a set of components that can be mixed and matched to build the right functionality; furthermore, components are loosely-coupled, designed to be both extensible and replaceable. Synth blurs the line between compile-time and runtime, and it does so by blending the static C++ type system, the dynamic values that need to be manipulated and formatted, including those from other languages, and the templates to do so. The name is an allusion to this synthesis process, which combines values to generate new ones (streams, files, strings, numbers, etc.)
HHVM (aka the HipHop Virtual Machine) is a virtual machine designed for executing programs written in Hack and PHP. It uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. To date, HHVM (and its predecessor HPHPc before it) has realized over a 9x increase in Web request throughput and over a 5x reduction in memory consumption for Facebook compared with the PHP 5.2 engine + APC. HHVM should be used together with a FastCGI-based Web server like Nginx or Apache.
The Link Grammar Parser (link-grammar) is a syntactic parser of English, Russian, Arabic, and Persian (and other languages as well), based on link grammar, an original theory of English syntax. Given a sentence, the system assigns to it a syntactic structure, which consists of a set of labelled links connecting pairs of words. The parser also produces a "constituent" (Penn tree-bank style phrase tree) representation of a sentence (showing noun phrases, verb phrases, etc.). The RelEx extension provides dependency-parse output.
