CCruncher is a project for quantifying portfolio credit risk using the copula approach. It is a framework consisting of two elements: a technical document that explains the theory, and a software program that implements it. CCruncher evaluates the portfolio credit risk by sampling the portfolio loss distribution and computing the Expected Loss (EL), Value at Risk (VaR), and Expected Shortfall (ES) statistics. The portfolio losses are obtained simulating the default times of obligors and simulating the EADs and LGDs of their assets.
Fairmat is a derivative and capital investments modelling tool. It permits you to build a pricing model for many financial projects (or derivative contracts) using a graphical representation blended with a high level algebraic language. It is also possible to use it to evaluate projects and perform real options valuations. The platform can be extended using a plug-in system.
NixBill Automation provides many features to manage your Web hosting business. It provides hosting modules, domain modules, payment modules, and encryption modules.

You can create as many encryption modules as you like to store different sets of credit card data differently.
The FIX message viewer is a set of Ruby scripts that parse FIX (Financial Information eXchange protocol) messages to display them in a more human-readable format. The viewer can only parse FIX messages in a file or from STDIN. It also expects a full FIX message on each line. The FIX message can be prepended with a timestamp, but this will be ignored. The output is colored to make it easier to read, and the MsgType field is highlighted. The log viewer works on the command line only, and requires that Ruby is installed.
StratosERP is a module set that allows you to use Drupal as a major part of your business operations in areas that Quickbooks and MYOB are lacking. The Drupal node system is used so that almost any other Drupal module can also be added to expand the power of the system. Existing Drupal modules are employed wherever possible, using Views, Gmap, Date, and Calendar modules in particular. The Stratos ERP module can act as the core of a small business, handling all aspects of it except tax reporting and employee payroll. Its features include franchises, stores, quoting/estimates, invoices, purchase orders, payment receipt, stock tracking over multiple stores with the option of tracking by serial number, job tracking, automated item/pricing import from CSV/XLS files via the Web or email, PDF generation of invoices for email, Ubercart item synchronization, POS instant login via RFID tag, and more.
Bitcoin is a peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.
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.
