Talk:Software components

Have you considered adding Mono as a software component of the OLPC?

If Sugar was running on Mono, it would make it easier to write Activities in languagues other than Python. For example Java, C#, possible Ruby: http://www.mono-project.com/Languages

IronPython is an implementation of Python that runs on Mono. It is supposed to be faster than CPython. There is a reference to that on the original IronPython page. The current IronPython page is: http://www.codeplex.com/Wiki/View.aspx?ProjectName=IronPython

I've read that the final version of the OLPC will run Windows (according to this article, that is why the SD slot was added). Will these applications also be on the final Windows version or will they be rewritten?

Applications that can be looked for integration in the Sugar environment

• Dr Geo, an interactive geomtery software which allows one to create geometric figure and manipulate it considering the geometric constraints associated with the figure.

• X-word, a GTK crossword puzzle program that reads and write puzzles in the Acrosslite format used by the

New York Times . It has printing, a clock, a word list, auto saving and options to check and reveal letters of the puzzle.

• Range Software Packages, a software for engineering simulations, finite element analysis and is able to solve problems based on heat transfer , radiation , stress strain , porous media flow and viscous incompressible flow.

• Ascend, an interactive mathematical modelling system for engineering and scientific applications capable of solving non linear systems containing 100,000 of variables.

• gElemental, a periodic table viewer that provides detailed information on the chemical elements.

• xyz2ila, a little C program to convert earth centred earth fixed(ECEF) cartesian coordinates to latitude, longitude and altitude.

• Lybniz, a simple function graph plotter in Python which can also be made to function as a graphing calculator

for the Sugar.

• Scilab, a numerical computation system similar to Matlab or Simulink.

• gElemental, a periodic table viewer that provides detailed information on the chemical elements.

• g3data, a program for extracting data from graphs.

• G Flashcards, a teaching tool for learning vocabulary lists or historical facts.

• Comix , a pyGTK based user friendly and customizable image viewer specifically designed to handle comic books but can also serve as a generic viewer.

• gretl, an application useful for teaching Economics Stastics.

• Shrinking Man, a diet tracker application that can be used for tracking your weight and the calories consumed

per day.

• Electric Form, an application that can be used for calculation purposes in the field of Electricity based on the relationship between Power(P), Current(I), Voltage(V) and Resistance(R) that is 'P=I^2*R', 'P=V*I', 'P=V^2/R' and 'V=I*R'.

• A basic quizzing web application with around 20 quizzes built by CERTY

In general web applications, while accessible from the laptops, will not be bundled onto the laptop. --Walter 02:50, 4 November 2006 (EST)

The problem with Mono is that it allows too many languages to be used, each of which requires its own support libraries. The OLPC doesn't have the storage to spare for Python libs, Ruby libs, C# libs, etc.

Python has the power to build the type of applications that would be useful in an educational environment. That's why it was chosen. The laptop also supports Javascript in xulrunner and csound. And programs can be written in C as well.

The laptop is not a PC in the conventional sense. It has very limited memory and will be used in a very different networking environment from a PC. Most software will need to be written specifically for OLPC or heavily modified to suit a very different environment. Python is the ideal language for this development work.
