The XO-3 tablet concept promises a different vision of computing  (Source: OLPC)
Even poor kids need faster computing

Over the last five years, the OLPC (One Laptop Per Child) project has sought to develop and distribute a low-cost and rugged computer to children around the world in a bid to raise global standards of living. The non-profit organization successfully developed the XO-1, and has distributed over 1.4 million of the netbooks for less than $200 each.

“The first version of OLPC’s child-centric laptop, the XO, is a revolution in low-cost, low-power computing. The XO has been distributed to more than 1.4 million children in 35 countries and in 25 languages,” said Nicholas Negroponte, the founder and Chairman of One Laptop per Child.

Mass production of the XO-1 first started in November 2007. Computer technology has made significant advances over the last two years, and the XO-1 is getting long in the tooth. The XO-1 features an AMD Geode CPU running at 433MHz, 256MB of DDR DRAM, and 1GB of SLC NAND flash memory for storage. A 7.5-inch screen with a 1200x900 resolution is used. Wireless networking is enabled by a chip from Marvell, while a built-in camera, microphone, and speakers add functionality. A variety of battery choices are available. The XO-1 only uses 2W to run.

The OLPC project will introduce a new XO-1.5 in January 2010 using the same basic design. However, it will drop AMD in favor of a VIA C7-M Ultra Low Voltage CPU which will double operating speed. DRAM will be increased to 1GB, while 4GB of flash memory will be the standard, with an option for 8GB. It will be capable of running Windows and Linux, and is targeted for a $200 price.

Two other designs have been added to the OLPC roadmap. The XO-1.75 is currently targeted for the $150 mark and an early 2011 launch. The design will be updated, with rubber-bumpers on the outside for added shock protection. A new 8.9-inch touch-sensitive display will be used. The project is working with Marvell on integrating a new ARM processor that will double speeds while cutting power consumption by 75%. This ARM-based system will complement the x86-based XO-1.5, which will continue to remain in production to give deployments a choice of processor platform.

The XO-3.0 is being developed for 2012 at a target price of less than $100. It will feature a new tablet design using a single sheet of flexible plastic, and will supposedly be unbreakable. The XO 3.0 will leapfrog the XO-2.0, a concept approach that the OLPC project decide not to pursue.

“To fulfill our mission of reaching 500 million children in all remote corners of the planet, OLPC will continue to innovate in design and performance. Because we are a non-profit, we hope that industry will copy us,” Negroponte added.

The XO-1 helped to establish that low-cost netbooks could be functional and affordable, and helped push Intel into developing the Atom. Former OLPC CTO Mary Lou Jepsen left the project to form Pixel Qi, a fabless firm which designs and and markets energy-saving screens that are readable in daylight. There is no word yet on which OLPC netbooks will use the technology, but Pixel Qi just entered mass production of its first 10.1 screens for use with new Pine Trail netbooks, and its future screens  are rumored to be used in Apple's tablet computer.

Walter Bender's Sugar interface has also been spun off. Originally designed for the OLPC project,  it is now being developed by Sugar Labs and is available for free under a GNU General Public License.

I have a hard time feeling sorry for teachers who spend all their time correcting homework. If they didn't assign so much, they wouldn't have to spend so much time correcting it.

When I was going through school, most of the homework assigned was merely busy-work and didn't contribute at all to the education of the students. Also, many teachers use HW as a crutch to avoid actually having to teach their students anything.

When my dad was in school they had no more than an hour of homework each night. In order to get A's, kids had to spend 6-8 hours every night just to get all their homework and studying done.

There is a big problem with this. A standard school day is 7 academic hours of class time. A student taking a regular full-time course load should spend 40 to 45 hours per week on academics (including both class and study/HW time). That would be 12-15 credits at college. 45 hours per week is 9 hours, 5 days per week. With 7 spent in class, that leaves a maximum of 2 for HW. Maximum. IMO, children should not be working more than 45 hours per week under any circumstances, and really shouldn't have to work any more than 40. I believe 1 hour should be the maximum total homework a kid should have in a night unless they voluntarily take on extra course load, with parental consent. For kids, HW needs to be just a brief exercise at the end of class to give the kids an opportunity to practice what they just learned. It also gives the teacher a clue as to who needs help before the test comes up and what they need help on. I believe this is what HW was in the past, but now it has become the end rather than the means.

My personal experience has been that this trend of excessive HW has a horribly detrimental effect on both education and quality of life for Americans.

I hate homework with a passion. Especially essays and reports in courses where the professor does nothing except ask questions and repeats what the other students says adding very little of his own opinion/points across. Thank goodness I've just finished my engineering degrees....no more of that liberal arts BS.
