The upcoming XO Tablet: A parent's perspective

Submitted by sverma on Tue, 2013-07-09 17:56

Every afternoon, when I go to pick up my daughters from school, I ask them "What did you do in school today?" Several years into the ritual, it has become a habitual question now, and I get varying degrees of responses from them, depending on their mood, and what they feel like sharing. To me, it's of paramount importance to hear it from them. At least until they stop sharing with me smiley

The Engadget Show 44 has featured OLPC among its other targets on education. Others include Google, LeapFrog, Adafruit, Sparkfun and more. First, I applaud Engadget for including OLPC in the mix. More importantly, the show includes OLPC's work in the US, especially in North Carolina through a series of projects run by the Knight Foundation.

File this under the "because I can" section. A while ago, when looking for replacements to Dropbox, I came across Tahoe-LAFS. A least authority file system, where your data is uploaded to a set of servers, where they all have pieces, encrypted before the upload by you, and a bare minimum is needed to recover the original.

Doodling on the XO-4 Touch

I was simply doodling on the XO-4 Touch. One thing led to another, and before I knew, I was adjusting brush sizes, mixing colors and finger-painting away. Given that the "touch" is based on infrared LEDs and photodiodes, the resolution and response is impressive - even for a terrible finger-painter like me!

Hint: I think those are really tall Redwood trees :-)

I've been playing with the camera and lens combo using the Tuk Lens Kit and a XO-4. The camera on the XO does not autofocus, like most smartphone cameras do. So, instead of holding the object steady, one has to move the object into focus, and while holding steady, click on the "circle" button.  I wanted to have a better way to move the object, and keep it steady for a picture - sort of like a microscope.
