This is an example of a writing robot Handwriting is quite a difficult task for robots, but children find the result interesting. This is a robot which carries a paper disc. The program is written round the edge of the disc with a black felt-tip, like a bar code. The disc is carried by the robot rather like music on a music stand, it bears on one of the robot's axles,which rotates it so that the code passes in front of a simple light pen. This works a relay which reverses the motor driving the other axle. A felt-tip is carried in the middle which traces out a simple pattern according to the program. A disc about 3 inches diameter is big enough, the novelty of writing the programs soon wears off. This next one is similar, but uses an electronic memory to store the program which it scans by rotating once on the paper disc, there is a downwards-pointing light pen at the end.

"Some of you may have heard a few popcorn farts re: our sites being threatened by hackers," wrote KISS bassist Gene Simmons on his website yesterday, responding to a DDoS attack that took down GeneSimmons.com earlier this week.
The attack was part of Operation Payback, a campaign that over the past few weeks has been targeting organizations who legislate and litigate in support of copyright laws. Loosely organized by Anonymous, a group of Internet "vigilantes" has launched a series of denial-of-service attacks against the likes of the MPAA, the RIAA, the UK Intellectual Property Office, as well as against the KISS bassman. The direct action campaign has effectively shut down sites that have been most vocal (and litigious) about their pro-copyright and anti-piracy stances. It has also targeted law offices that have been deemed to be part of a what TorrentFreak has called "pay-up-or-else" schemes, threats of legal action aimed at alleged file-sharers.
First, they will be punished. Sharp Stone Age spearheads were cooked then flaked - life - 28 October 2010. If you want to make really sharp stone spearheads, do like Stone Age cave dwellers did and cook them first. Palaeoanthropologists have discovered that this two-step trick was invented 50,000 years earlier than they previously thought. The findings add to evidence that Africa's southern tip was a centre of technological and cultural development during the middle Stone Age.
The key technique, known as pressure flaking, was used to make finishing touches to stone spearheads. Pushing a narrow tool against one side of the spearhead releases a thin flake of material from the other side. Paola Villa of the University of Colorado at Boulder and her colleagues have spent years analysing artefacts found in the Blombos cave near Still Bay in South Africa, including some 75,000-year-old spearheads made of a cement-like substance called silcrete they had found there.
Then last year another team discovered that some of the artefacts had been heat-treated. Make your own More From New Scientist.
