repasa is a set of three kind of tools: For creation of contents directly in the XML format of repasa or in other file formats (DocBook and LaTeX) following some conventions, for checking the contents, and for studying the contents and registering progress.

The contents can be specified with definitions, classifications for the definitions (possibly along with exercises), and sequences of study. repasa project is especially well suited to organize information according to the current legislation for education in schools of Colombia

AspectES is an implementation of Aspect-Oriented Programming in JavaScript 1.5, as standardized by EcmaScript Specification 262.
AspectES project contains core classes that enable software engineers to gracefully develop JavaScript applications that have clear, well-documented designs that incorporate Aspect Oriented Programming.
This project only uses standardized Web technologies: JavaScript 1.5, with no proprietary extensions. The framework is documented with JavaScriptdoc.
Mission:
Produce a superior implementation of Aspect-Oriented Programming in JavaScript v1.5, as standardized by EcmaScript Specification 262.
Scope: A package framework that contains core classes that enable software engineers to gracefully develop JavaScript applications that have clear, well-documented designs incorporating Aspect Oriented Programming.
Agenda:
Current:
- This framework powers the drag-and-drop capability in the (open-source) Gigapan Explorer Application, delivered to the United States NASA in late 2005.
- This project only uses standardized web technologies: JavaScript 1.5, with no proprietary extensions.
- Enjoy complete JavaScriptdoc as you develop this codebase.
- See the Coding Standard.
- See the tips on Debugging JavaScript.
Immediate Future:
- Develop a test suite that completely exercises the existing functionality.
- Log and fix bugs on said functionality.
- Identify additional desired functionality.
- Build a pluggable module for generating JavaScriptdoc from AspectES aspects and their associated yarn.
Enhancements:
- This version is now contained in its own tigris.org project, separate from the Gigapan Explorer application for which it was originally developed.

Mecanica project is a simulation software for classical mechanics.

Its written in Portuguese and should help physics students to solve their exercises.

Keen little rabbit ears is a simple ear training program for Linux and Windows. It is free of charge. You can exercise the recogniton of intervalls, chords, scales and chord progressions.
Keen little rabbit ears requires the installation of Perl (Version 5), Perl/Tk, Perl::MIDI and an extermal MIDI player, like timidity (Verion 0.2i). Keen little rabbit ears is written in perl, uses Perl/Tk for the user interface, Perl::MIDI to write MIDI files and timidity to play MIDI files.
This is an early release, which means that there is a number of features which are not implemented. But keen little rabbit ears works pretty fine on my Pentium 90 using Suse Linux (Version 6.1) and under Window 95 too.
I strongly recommend everyone to read a good book on this. There are several ways to train. In general you do it like this. In the first level only select 2 or 3 items you already know or which are
the most common. In the next level you proceed and add the next 2 common items.
Below is are two lists, which can be used as guideline. But it is usually better to ask your teacher which exercises should you train.
Enhancements:
- Quiz mode
- advanced root note selection
- extension to playing direction (both)
- highlighting of selected instrument / root note
- 440 Hz (sing an "a" test)
- bug fix (pitch drill)

Raw Print Server project is a "raw" print server that makes it possible for a computer to act as a "Socket API" or "AppSocket" print server.
This software would not exist without Sam Rushings excellent asyncore module, nor would it exist without Steve Holdens excellent explanation of that module (in his book "Python Web Programming" from New Riders, a truly outstanding book that I cant recommend enough) from which I learned enough to write this server. Im also indebted to Guido van Rossum for Python itself, which has made my life SO much easier, and to Mark Hammond for the win32all modules which are essential parts of the Windows version of the print server.
This is version 0.1 of the Raw Print Server. There are no installation instructions to speak of; I plan to write an install script to assist with getting the software up and running, but for now its all manual.
You will need a working Python 2.x system to run the print server itself, and if you are installing on Windows youll need a working set of the win32all modules from Mark Hammond (which you really ought to have anyway). To run the GUI properties program, youll need a working PyGTK module set, and on Windows that means finding a compatible GTK+ runtime also.
Finding all of the above is left as an exercise for the reader.
Okay. If you are on a recent Linux system, or any of the BSD family, you should be able to install all of the above from your original installation media, or download them from the appropriate website for your distribution.
If you are running Windows, start by getting a recent Python build from www.python.org; follow the links from that site to the win32all downloads (currently somewhere on Sourceforge).
After that, go to www.pygtk.org and follow their links to the downloads you need for Windows. Note that as of this time (October 2005), the GTK libraries normally used for the Gimp dont work with PyGTK (despite notes on the PyGTK for Windows site saying that they do), at least, not on Win9x.
Get the runtime or development libraries referenced from the PyGTK for Windows site. If you already have the Gimp installed, uninstall the GTK+ libraries you got with it before installing the alternate runtime. My Gimp still works, so it must be okay, right?
Enhancements:
- close printer when done

GenChemLab is an OpenGL-based application intended to simulate several common general chemistry exercises. It is meant to be used to help students prepare for actual lab experience. It could also be used in cases where laboratory facilites are not accessible, for instance in K-12 schools or home schooling.

At present, supported experiments include titration, calorimetry, freezing point depression, vapor pressure, and spectrophotometry.

PerlActor is a simple automated executable acceptance test framework for Perl.

PerlActor is a simple automated executable acceptance test framework for Perl. It can be used by Extreme Programming (XP) teams to rapidly develop executable acceptance tests for their Perl code.

XP mandates that the Customer writes acceptance tests for the application under development. The acceptance tests, also known as customer tests, demonstrate that application features are complete and that they work as expected. Ideally, the tests should be directly executable and automated so that they can be run continuously, without manual effort.

PerlActor enables an XP Customer to write *executable* acceptance tests as plain text files, using a very simple syntax. Each test consists of a number of parameterized commands (one per line), which PerlActor uses to exercise the application. PerlActor parses the test, invokes the commands with any parameters, and reports the result. The developers provide glue code to implement the commands required by the tests.

PerlActor allows tests to be grouped into suites so that related tests can be run as a group. The Customer can also just place test scripts in a directory structure and have PerlActor find and execute them all.

The PerlActor approach to acceptance testing has a number of advantages:

1) As the application grows the team will gradually develop a comprehensive set of Commands for testing the application.
2) The Customer, independent of the development team, can write and execute new tests for the application at any time, using any of the existing Commands.
3) Existing tests may be changed by the Customer at any time, again without developer help.

EXAMPLE SCRIPT

The following sample test script is adapted from one of the example scripts contained in the examples/calculator directory of this distribution. It tests a toy calculator "application":

# Script to check addition
# 10 + 32 = 42

# Create a new calculator application
NewCalculator

# Ensure that the display reads 0, initially
CheckDisplayReads 0

# Press key 1, then key 0
PressKeys 1 0
CheckDisplayReads 10

PressKeys +
CheckDisplayReads 10

PressKeys 3 2
CheckDisplayReads 32

PressKeys =
CheckDisplayReads 42

The following is sample output from the included test runner:
