CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

Precise Calculator has arbitrary precision and can calculate with complex numbers, fractions, vectors and matrices. Has more than 150 mathematical functions and statistical functions and is programmable (if, goto, print, return, for).

TXM is a free and open-source cross-platform Unicode & XML based text analysis environment and graphical client, supporting Windows, Linux and Mac OS X. It can also be used online as a J2EE standard compliant web portal (GWT based) with access control built in. DOWNLOAD LATEST VERSION OF TXM : http://textometrie.ens-lyon.fr/spip.php?rubrique61&lang=en TXM offers a comprehensive range of analysis tools (concordances, collocate search, frequency lists, etc.) based on the powerfull CQP full text search engine (http://cwb.sourceforge.net) and a range of statistical functions (factorial analysis, classification, cooccurrency analysis, etc.) based on R packages (http://www.r-project.org). Read the scientific background at the Textométrie project web site http://textometrie.ens-lyon.fr/?lang=en. Read a full description at the TEI Tools wiki http://wiki.tei-c.org/index.php/TXM.

Approximator is program for experimental data approximation and interpolation (20 dependencies for select). Graphical charts. Export to Gnumeric/OpenOffice Calc/Microsoft Excel. Multi-language interface.

A simple DOS program pack that can very smoothly take some engineering calculations. It's fully written in russian, but I working over it's english version.

The fast powerful CALC is a desktop scientific calculator, still is under development and tests. The objective is offer a good and easy to use mathematical tool. I hope you enjoy it.

Over 75 C++ function for working with vectors, matrix and quaternions. Inside the package there is no cycles, if's, classes or structures. Ideal for designing 3D engines. Headlines of functions are intuitive. For each headline there is a one line comment in Russian. Matrix are presented in OpenGL form 0 4 8 12 1 5 9 13 2 6 10 14 3 7 11 15 Now we are working on adding 50+ more functions for processing the planes, splines, bezier curves and interpolation methods.

FVM2 is VM for running machines like Markov algorithms, Turing machine and so on. FVM2 has debugger with step mode and breakpoints. Goal of this project is to help students with studying Theory of computation. FVM2 shows how complex code works within a real machine. Currently the only implemented machine is Markov algorithms.
