Walter Bender — Taking Sugar Beyond the XO Laptop
waderoush writes "While the One Laptop Per Child Foundation tries to reboot after drastic staff cuts, Sugar, the original open-source graphical interface for OLPC's XO Laptop, is rapidly evolving into a stand-alone learning platform that can run on any PC. Walter Bender, who left OLPC last year to start the non-profit Sugar Labs, has given a detailed interview about 'Sugar on a Stick' — the USB drive that allows any machine to boot into the Sugar environment. Bender also describes the Sugar upgrades coming in March — including better tools for file management, portfolio presentations, and Python code hacking — and talks about his hopes for expanding Sugar Labs and getting Sugar into more classrooms than OLPC can reach through its hardware."

... "A Young Lady's Illustrated Primer" and infused it with nanotech, but that's just me.
What I found most interesting about the OLPC wasn't Sugar, the networking, or even the hardware. It's the Bitfrost security system, which is a different take on implementing security.
To my mind, it presents a radical way of approaching security, and seems entirely different from that taken by Microsoft. That is, instead of locking out applications based on whether they have proper credentials, it locks applications out based on bad behaviors.
I'd like to see this approach taken and explored more fully. Linux and other Open Source OSs will be facing more exploits and attacks, and a security model based on how trustworthy an application behaves instead of the credentials it carries seems a much saner approach.
Before everyone that has an XO goes crazy and start dumping on Sugar, please remember the target market. Put it in front of an elementary age student and see how easily they take to it. Of course, I've noticed that they take to even inefficient desktops pretty quickly also. It is old people (like teenagers) that can't handle having an icon moved.
A lot of people bash the environment as being bad. But I doubt they use it. It is a bit different that a PC/MAC but really other than file storage (which you can do via the terminal the old fashioned way) it is really a good interface. I actually have one, and would use it more if I actually bought a USB keyboard. That keypad is not much better than a cell phone qwerty pad (other than the spill resistance and cool green color).

My TV has a USB port. (It is there for firmware updates)
Can this boot Sugar on to my TV?

I read the article, and one of Walter Bender's comments jumped out at me:
This is the best thing about Sugar for the long run. In the old days of Apple ][ or Commodore 64 computers, lots of software was written in BASIC; and it wasn't too hard to interrupt the program, look around inside it, and even tweak it a bit. The hardest part was the sucky BASIC language. Now Sugar is being explicitly designed to not only make this kind of tweaking possible, but encourage it and make it as easy as possible. And Python is the best language they could have possibly chosen for encouraging school kids to try to tweak things.
If you read the article, you can read about how they have extended the "Turtle Art" program to allow programming the turtle movement in Python. So someone can learn trivial programming by chaining control blocks together, and then learn somewhat more advanced programming to script a special block in Python, and then perhaps move from there to tweaking the behavior of other parts of the system.
P.S. The OLPC project proper seems to be walking away from this sort of constructionist learning; putting Windows on a laptop is the total opposite of the above approach. I really wonder what Negroponte is thinking.
