It's time for one of our semi-regular looks at some of the best stories and features out there on the web.

IT Pro Portal has an interesting story about the Chinese authorities shutting down the country's biggest "hacker training centre". Of course, this comes just weeks after Google claimed that its own services in China were being targeted by hackers.

Network World looks into claims that there is a shortage of data centre expertise on the market, especially in the virtualization space. Very apposite given our roundtable on virtualisation today here on IT Galaxy.

BBC News has a fascinating piece looking at how mobile devices could benefit from a trick in quantum physics to create pressure sensitive touch interfaces. I'm no expert in quantum physics but essentially scientists have created a material that can detect different pressures by taking advantage of a phenomenon called "tunnelling". I suggest you read more if you want to really understand how it works.

The Rackspace website has a post rounding up stats from uptime monitoring firm Pingdom.com Apparently, in 2009 over 90 trillion e-mails were sent across the net.  Every day 200 billion spam e-mails are sent - and most of them seem to land in my inbox.

Smaller and more efficient home consumer electronics could be on the way if a Sony innovation takes off. The Register reports on Sony's new wireless technology designed to replace wires inside devices. Instead of using wires, the technology can transmit data at very high speeds but at extremely short distances.

From the Register: "Using a 1mm antenna, Sony was able to get a 11Gb/s transmission speed over a distance of just 14mm. The effort used 70mW of power. Better, more directional aerials can be used to get the distance up to 50mm"

And why do this? Well, it could mean the replacement of components inside devices making them more power efficient and even smaller.
