An anonymous reader writes "What better way is there to learn something than by making your own DIY gadget? Here's a new video showing how to use a common hobby servo, in conjunction with a small water pump, to create a USB controlled water gun! You can use your keyboard to aim and fire at an unsuspecting passerby. Both fun and educational, this project looks like a great DIY weekend project for any IT guy, wanting to make sure people think twice before asking a stupid question!"

holy_calamity writes "CERN have released images of the damage done to the world's most powerful machine, the Large Hadron Collider, when an electrical fault caused a helium leak. New Scientist has posted them, along with explanations of what you can see. The sudden burst of gas shifted some of the huge superconducting magnets by half a meter, causing at least $21 million in damage."

I don't know why they need such a big grid, according to the inquirer they only create about 15 Gigs of data each year.

No, 15 million gigs - now you see! And yes, a full detector read out consists of every non zero channel in the entire detector which comes to about 3 Mb per event and we readout ~200 events/sec. And there are 4 main detectors each doing this. Not even mentioning the processor power to run statistical analysis on these data sets!
