A portfolio-optimizer using Markowitz(1952) mean-variance model
PortOpt [Portfolio Optimizer] is a C++ program (with Python binding) implementing the Markowitz(1952) mean-variance model with agent's linear indifference curves toward risk in order to find the optimal assets portfolio under risk. You have to provide PortOpt (in text files or - if you use the api - using your own code) the variance/covariance matrix of the assets, their average returns and the agent risk preference. It returns the vector of assets' shares that composes the optimal portfolio. In order to minimise the variance it internally uses QuadProg++, a library that implement the algorithm of Goldfarb and Idnani for the solution of a (convex) Quadratic Programming problem by means of an active-set dual method. This solution is very efficient as it allows to solve hundred of thousand of portfolio problems in seconds. PortOpt runs as a text/console tool so it can be easily used in your own scripts.
SMS API for sending and receiving sms's through reachit's API
Very lightweight and minimalist spreadsheet application. Through a notepad-style interface, you create informal spreadsheets with formulas as powerful as any full-sized spreadsheet program. It can also serve as a calculator with revisable history.

Artificial Intelligence and Statistics for Excel
Xlai is an open source Add-In for Microsoft Excel. Xlai adds artificial intelligence capabilities to Microsoft Excel and a host of non-parametric analysis methods. Xlai's focus however, is on neural networks, in the forms of multi-layer perceptrons (FFANN) for numerical logistic regression (various optimisation techniques are included, ranging from evolutionary to back-propagation). Xlai has the ability to find relationships between continuous variables. Combined with the other statistical features included in Xlai (Bayesian classifiers, kendal tests, MANOVA), this makes for a powerful tool for regression analysis.
