Overview

The OLPC Trojan horse is the ebook and the soldiers inside the horse are children and teachers with laptops.

The way to penetrate the walls of the Education Industry is through the more efficient creation of instructional materials--the traditional textbook.

Once we are inside, the opportunities to move instructionism towards constructionism--learning through doing--abound.

  1. teachers (and children) can construct lesson plans and other learning materials;
  2. they can share these materials;
  3. they can engage in a critical dialog about these constructions.

Thus we can infect the Education Industry with the ethics, methodologies, and efficiencies of the Open Source community.


A matrix of applications for the laptop can be found here.

OLPC software is a set of carefully chosen and integrated Linux applications, creating an innovative user environment.

Basically, the laptop runs the Fedora Linux distribution; On top of the X Window System and the Matchbox window manager, we run a novel "Sugar" user interface and support library, supporting a core set of "activities". Activities are programs that follow the OLPC Human Interface Guidelines. There is an emphasis on Python and GTK. Other Linux software can be run too, but having a common and enabling user interface is nice; requiring additional libraries (KDE, java runtime, whatever) is in tension with disk and memory limits.

In regard to OLPC software, you can:

If you are comfortable reading python and writing documentation, much new code is in need of doc strings, tutorials, etc. (sugar, geckoembed, ...what else?)

Some Details

(This section needs to be updated)

There are four flavors of software:

  • Activities, written or ported to the Sugar user interface, and following OLPC interface. Activities are mainly written in the python and C programming languages. The standard libraries are listed in software components.
  • Code written for a programmable activity, such as squeak and its etoys, OLPCities(?), javascript(?), ...(?).
  • Linux software using the standard libraries listed in software components.
  • Any other linux software. Memory and disk space are constrained (256MB,1GB), so requiring additional libraries makes this a less attractive option.

Some content to integrate

This text went by on boston-pig, from doug. It should be integrated above.

The project needs help on just about every level. There are open tickets at http://dev.laptop.org/ for documentation, translation, python programming, c kernel programming, UI work, and of course bugs. There is a special section of bugs for people who are not familiar with the system but want to help out: http://dev.laptop.org/query?status=new&keywords=%7Esugar-love&order=priority

These are bugs in sugar which are already triaged which good instructions on how to fix them in most cases and can be fixed with the LiveCD.

The CD's that were available are the LiveCD from here: http://wiki.laptop.org/go/LiveCd in case you didn't get one.

There are other ways to check out the XO and do development but the LiveCD is the easiest. Here is a good link for other forms of emulation: http://wiki.laptop.org/go/Software

Because Sugar (the core interface) is GTK+ python based, you can run it and do development for it anywhere those packages are available (Mac, Linux, win32). Linux is the easiest and best documented.
