Re: Interested in the Google Summer of Code
I just signed up to the developer's list a few days ago (After seeing an XO live for the first time at SigCSE 2008 in Portland) and would love to work on the OLPC as a Google Code project. I look forward to seeing more information on this. In the mean time I'm going to continue figuring out how to get Sugar up and running and get my feet wet with the development platform. Thanks! Blaine 2008/3/18 Bobby Powers [EMAIL PROTECTED]: Hi, I'm a master's student at the University of Bergen and I'm interested in bringing System Dynamics to the XO. Before I start, if there is a better mailing list for this just let me know (I briefly looked through the other ones liked from the Wiki, and this seemed the most appropriate). System Dynamics (SD) [1][2] aims to help people understand the world by explicitly modeling how pieces of it work and then performing experiments in these models. It is used around the world, frequently in majority world countries, in development planning [3], for example. More formally, its a methodology for examining and describing the behavior of complex systems with an emphasis on the effects that feedback loops and time delays have. At a basic level you have to specify the mathematical equations for the different parts of your system. The same problems can be solved by writing code in a programming language (I had a course taught in Fortran a year ago...), but usually in SD the modeling is done using a visual editor where you can show causal relationships, stocks and flows graphically. I personally think the biggest short-fallings of the discipline are the barriers to entry: the current software is far from intuitive and all the major commercial offerings (there are no FLOSS products) [4][5][6] are very expensive (educational licenses alone are frequently $500 USD). Will Wright studied SD and used ideas from it when designing SimCity [7]. So I have several things I would like to work on: first is a core simulator that can transform equations into code (I'm currently working on this for my master's thesis, but don't have and funding. eesh): I'm using the JIT library from the LLVM project to be able to do this. Second I want to create a Sugar modeling interface that makes it easy and fun to create models and explore their results (collaboratively, I hope!), and third I want to hook this into Metropolis. I think it would just be so cool if you could click an icon in Metropolis and have the visual model that controls the Metropolis world pop up (in the aforementioned editor) and be able not only to fiddle with parameters, but change the structure! If all of this goes smoothly and there is more time, I would love to add the ability for models to interact with and manipulate geospatial data. I guess I am looking for people's reaction, is this something people like? I'm certainly willing to adapt myself to the collective needs and I wanted to get a discussion started before the application deadline. Oh I guess a little more background on me: I attended RPI in NY, USA for 2 years studying computer engineering, but transferred because I wanted to do something more applied. I studied environmental studies (at SUNY ESF) for a couple years, and got back into coding through classes on ecological modeling and GIS. I've been pretty heavily coding models, algorithms and interfaces for the past 2 years, mainly in C#, ObjC and some Fortran, but the past 3 months I've been using C++ for 8 hours a day and Python here and there. I've got a Mac with Linux (both FC8 and openSUSE10.3) and Windows, and I've just started over the past few weeks to pick up GTK, although I've used Cairo in a project for a couple months. I've only dabbled with the XO, but am really looking forward to developing bundles for it.

Re: Interested in the Google Summer of Code
Hi, if you are interested in hacking Sugar, please check the roadmap in the mail below and find something you would have fun working on: http://lists.laptop.org/pipermail/sugar/2008-March/004546.html I would recommend people interested in participating in the google summer code to send an email to the sugar mailing list presenting themselves and, most importantly, stating the mini-projects they would like to work on. Chances are high that, if the area to work on is in the roadmap, one core developer will offer his mentorship. Unfortunately, in this precise moment developer's time is very scarce and there's not much time for medium-term goals. But of course, everybody is free to work on whatever they want and I personally will try to answer as many questions as possible.

I guess I am looking for people's reaction, is this something people like? We don't just like it. Some of us are quite excited about it. We started a discussion not long ago involving. * Engineers Without Borders * The Geographic Information Systems community, including International Symposium on Digital Earth * Globe.co.uk (weather stations in schools in many countries) * Timepedia.org (geographic and other free time series data) about community data gathering of environmental information, feeding to global mapping, and feeding from there back to communities and out to NGOs, governments, and international organizations. We are also discussing collection of health information, and anything else that we can feed into a computer that bears on the needs of the children and their communities. So the prospect of an engine that can start from our data and give us a peek into various possible futures is a jump up and dance type of idea. I'm certainly willing to adapt myself to the collective needs and I wanted to get a discussion started before the application deadline. Excellent.
