The symeig module contains a Python wrapper for the LAPACK functions to solve the standard and generalized eigenvalue problems for symmetric (hermitian) positive definite matrices. Those specialized algorithms give an important speed-up with respect to the generic LAPACK eigenvalue problem solver used by NumPy (linalg.eig and linalg.eigh).

rpCalc started out as a little program written to try out various Python GUI toolkits. But I ended up using it all the time (it's much quicker to pull it up than to pull an actual HP calculator out of the desk), and I made several improvements. So I decided to make it available to others who also like RPN calculators.

SNNS (Stuttgart Neural Network Simulator) is a software simulator for neural networks on Unix workstations developed at the Institute for Parallel and Distributed High Performance Systems (IPVR) at the University of Stuttgart. The goal of the SNNS project is to create an efficient and flexible simulation environment for research on and application of neural nets. The SNNS simulator consists of two main components: 1) simulator kernel written in C 2) graphical user interface under X The simulator kernel operates on the internal network data structures of the neural nets and performs all operations of learning and recall. It can also be used without the other parts as a C program embedded in custom applications. It supports arbitrary network topologies and the concept of sites. SNNS can be extended by the user with user defined activation functions, output functions, site functions and learning procedures, which are written as simple C programs and linked to the simulator kernel. The graphical user interface XGUI (X Graphical User Interface), built on top of the kernel, gives a 2D and a 3D graphical representation of the neural networks and controls the kernel during the simulation run. In addition, the 2D user interface has an integrated network editor which can be used to directly create, manipulate and visualize neural nets in various ways.

wxMaxima is a wxWidgets GUI for the computer algebra system maxima. Most of maxima functions are accessible through menus, some have dialogs. The input line has command history (up-key, down-key) and completion based on previous input (tab-key). wxMaxima provides 2d formated display of maxima output.

Bbjd is a tool to calculate the optimum strategy playing Black Jack. This program may be used to prove that when playing Black Jack it is possible to beat the casino. Probably, Black Jack is the only game offered by casinos, where it is possible to win in the long term (and this fact is mathematically proven).

The Free Software Foundation's "find" utilities, including "find", "locate", and "xargs". These utilities exist in the FreeBSD base collection, but the GNU versions have added functionality that is sometimes useful. Note that this port will install these utilities with a `g' prefix, eg., glocate, gfind, gxargs, but the texinfo documentation will refer to these utilities without the `g' prefix.

detachtty is a Unix utility that lets you run interactive programs non-interactively, and connect to them over the network when you do need to interact with them. It's intended for use with long-running server processes running in Common Lisp implementations.

GCstar is a free open source application for managing your collections. Detailed information on each item can be automatically retrieved from the internet and you can store additional data, such as the location or who you've lent it to. You may also search and filter your collection by many criteria.

The General Cartographic Transformation Package (GCTP) is a system of software routines designed to permit the transformation of coordinate pairs from one map projection to another. The GCTP is the standard computer software used by the National Mapping Division for map projection computations.
