Byte-size news: Putting a stop to that random naked guy

The latest internet fad, Chatroulette.com, is cleaning up its act - or should that be the antics of some of its more dubious members.
Originally launched in November by Russian teenager Andrey Ternovskiy, the site had the noble intention of connecting internet users around the globe by randomly pairing up webcam users to have a chat.
"Chatroulette was great in the first honeymoon days after it was launched, before it was discovered by strange people who started to abuse the true freedom and democratic nature of the service," Mr Ternovskiy said in a blog post.
The strange people he refers to are the approximately one in 10 who have a tendency for showing a bit more of themselves than expected.
"We've blocked thousands of IP addresses, reported offenders and the service seems to be much cleaner than before," he said.

Curry - the climate's saviour
Not just delightful spices to fire up your curry - coriander and turmeric might just save the world.
Well, that might be overstating it a tad, but research by Newcastle University has found the the fiery flavours can reduce the amount of methane produced by bacteria in a sheep's stomach by up to 40 per cent.
"Spices have long been used safely by humans to kill bacteria and treat a variety of ailments - coriander seeds, for example, are often prescribed for stomach complaints while turmeric and cloves are strong antiseptics," research student Mohammad Mehedi Hasan said.
The study looked at cumin, coriander, clove, turmeric and cinnamon with each being ground up - like a sheep would chew it - and added to an in-vitro solution mimicking the rumen of a sheep.
Coriander came out on top; dropping methane production by 40 per cent, followed by tumeric with a 30 per cent reduction.
What's that FitzRoy? You say a storm's coming?
NIWA's recently welcomed a new adddition to its arsenal - a $12.7 million IBM p575 POWER6 supercomputer dubbed "FitzRoy".
This computing juggernaut is one of the most powerful computers in the world for use in environmental research and forecasting, and is the most powerful in the Southern Hemisphere.
Housed in a specially constructed computer room at NIWA's Greta Pt base, FitzRoy has 100 times the power of NIWA's existing supercomputer, equivalent to about 7000 laptops working simultaneously. When fully installed, it will weigh 18 tonnes, meaning the floor had to be custom-strengthened to hold its weight.
It has 500,000 gigabytes of disk storage and its two tape libraries will hold another 5 petabytes (5 million gigabytes) of data - the equivalent of a 3000-year-long MP3 file.
"To have access to such an incredibly high-powered supercomputer opens up a whole new world for NIWA and for New Zealand science," John Morgan, NIWA chief executive, said.
An economic study of a similar computer used by the UK Met Office found the benefit to cost ratio was nine times the cost of the computer, based on its ability to improve flood forecast lead times.
Why FitzRoy as a name? History buffs will tell you he was the second Governor of NZ and also the first person to do data assimilation and produce a weather forecast.
