Novel OS Drives the '$100 laptop'
jrwr00 writes with a link to a CNN story about the $100 laptop's unique operating system. We've discussed the OLPC's UI before but the article offers a few new piece of information on the project, which is expected to roll out this year. From the article: "The XO machines are still being tweaked, and [OLPC UI] Sugar isn't expected to be tested by any kids until February. By July or so, several million are expected to reach Brazil, Argentina, Uruguay, Nigeria, Libya, Pakistan, Thailand and the Palestinian territory. Negroponte said three more African countries might sign on in the next two weeks. The Inter-American Development Bank is trying to get the laptops to multiple Central American countries."
AbiWord. We have kicked abiword into a library, with the GUI stripped off. This allows one to build a GUI on top of it in python, like the rest of Sugar is. Seamless integration. This will be the writing Activity the children will use. Then we are working on special import/export filters for abiword to read/write the 'fileformat' of choice of sugar: crossmark. This will allow perfect integration with the Journal. Neat trick is that you can even embed abiword in mozilla to do inline editting.
Also, a collaboration plugin for abiword is being worked on, that will use the mesh infrastructure and sugar presence framework to find and communicate with other users. This will allow realtime collaboration on documents (for example, 2 or more children working on an assingment simultaneously).
So there you have an application that takes full use of the offered platform.
Most of Sugar, the OLPC's desktop environment, is written in Python. The source is here:

I just tried it out, and I am pleasantly surprised! It's amazing how much faster Python is for desktop applications than Java is. Even when using IBM's SWT for developing Java applications, they still feel far more bloated and slower-responding than OLPC's Python-based GUI applications.
I would have expected Python to be slower than Java, but apparently that is not the case. It could be that the layers upon layers that make up Swing really slow it down. Maybe it's time for Sun to take a page from OLPC's Sugar project, and develop a UI framework that is fast and easy to use.
