OLPC tablet distribution proves concepts laid out in ‘The Diamond Age’

We don’t remember hearing about the One Laptop Per Child initiative distributing tablet computers but apparently a couple of shipments were distributed to rural communities in Ethiopia. The problem one might think of in this scenario is that the literacy rate in the two test villages was basically zero. But that’s exactly the population targeted with thr technology.

Going as a Fembot from Austin Powers: International Man of Mystery sounds like a lot of fun … Read the rest

Computer tracking of billiard balls

The folks at the London-based startup GoCardless have a pool table at their office. Being the techies they are, they decided to build a system that automatically scores games. The results, while not fully complete, are still pretty impressive for something whipped up during a 48 hour hackathon.

The automated score keeper uses a webcam duct taped to the ceiling … Read the rest
