The Open-Transactions project is a collaborative effort to develop a robust, commercial-grade, fully-featured, free-software toolkit implementing a full-strength financial cryptography library, API, CLI, and prototype server. Open-Transactions democratizes financial and monetary actions. You can use it for issuing currencies/stock, paying dividends, creating asset accounts, sending/receiving digital cash, writing/depositing cheques, cashier's cheques, creating basket currencies, trading on markets, scripting custom agreements, recurring payments, escrow, etc. Strong crypto is used. Balances are unchangeable (even by a malicious server). Receipts are destructible and redundant. The transactions are unforgeable. The cash is untraceable. The cheques are non-repudiable.
MyMediaLite is a lightweight, multi-purpose library of recommender system algorithms. It addresses the two most common scenarios in collaborative filtering: rating prediction (e.g. on a scale of 1 to 5 stars), and item prediction from implicit feedback (e.g. from clicks or purchase actions). It contains dozens of recommender engines, including state-of-the-art matrix factorization methods. It also supports real-time updates to the recommender engines, storing engines to disk and reloading them again, and several evaluation measures to compare the accuracy of different recommender system methods. Three command-line programs that offer most of the functionality contained in the library are included.
OSCATS (Open-Source Computerized Adaptive Testing System) implements Item Response Theory (IRT) and cognitively diagnostic (latent classification) models and item selection algorithms used in Computerized Adaptive Testing (CAT). OSCATS facilitates the development of CATs and simulations of CATs by providing ready-to-use code for running the CAT item selection and ability/classification estimation in an extensible, modular framework. The library is written in object-oriented C using GObject, and has bindings to Python, Perl, PHP, and Java.
RedWolf is a security threat simulator that tests security system effectiveness. Its threat generation capabilities include email, IM, malware, P2P, social networking, VoIP, DDoS, and many more. The guiding philosophy is that by generating realistic scenarios in a wide variety of categories, an auditor or organization can assess the effectiveness of network defenses. The scenario suite allows one to verify compliance with PCI-DSS, Sarbanes-Oxley, or HIPAA controls. RedWolf helps identify data loss risks and provides expert recommendations concerning risk mitigation. It reports present findings, recommendations, best practices, and blocking guidance in a straightforward, easily readable format. RedWolf also acts as a 'Red Team' agent, running drills to measure the readiness of your operations staff.
CTL is a cross-platform control dispatching tool that makes it easy to automate any kind of distributed systems management or application provisioning task. Rather than writing complex and error-prone scripts that over utilize "for loops", CTL handles the network dispatching for you and allows you to focus on the actual management tasks you need to accomplish. In addition to being a dispatching tool, CTL comes with pre-built cross-platform utilities so you don't have to script actions like file distribution or process and port checking. You can also write your own custom utilities and share them with others in your organization. Custom utilities are defined in XML, and your scripting can be done in multiple scripting languages (Perl, Python, etc.), *nix shell, Windows batch, and/or Ant.
Funpidgin is a modified version of the Pidgin instant messenger application. It was made in response to the controversial auto-resizing textbox that was implemented in Pidgin. Current features of Funpidgin include manual resizing and the ability to turn off persistent window placement. Funpidgin's releases are meant to coincide with Pidgin's releases.
