Scientists plan to test whether sharks enjoy listening to Christmas pop songs, after US research showed fish could recognize melody. Chris Brown, senior marine biologist at the Loch Lomond aquarium, said seasonal music would be played through walkthrough underwater tunnels where they can be heard by dozens of nurse sharks, black-tip reef sharks, and ray species. Experts will then monitor the sharks' reactions to different songs. We'll play everything from Kim Wilde and Mel Smith's Rocking Around the Christmas Tree and Merry Christmas Everybody by Slade to Wham's Last Christmas. We may find they prefer something softer like White Christmas by Bing Crosby," Brown said. Thank you for answering this question science.

Dr. Zowie writes "The 10th annual Nethack Tournament just started over at nethack.devnull.net, so put on your Hawaiian shirt, grab an expensive camera, and head for the dungeon. The tourney runs through the month of November each year, with volunteer game servers dotted around the world. Fewer than 1% of contestants actually finish the game by retrieving the Amulet of Yendor and ascending to demigodhood, but take heart: there are many prizes for intermediate goals, and prizes for team effort. For those too young to remember games older than Halo, Nethack is the apotheosis of the Roguelike genre of role-playing games, rendered in ASCII. Gameplay is phenomenally complex, and the game is somewhat sadistic; there are no 'checkpoints,' so if you manage to kill yourself somewhere in the dungeon you must start over from the beginning. The dungeons are quasi-randomly generated, so every game is different."

'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008."

Whiteox writes "The Australian Prime Minister's plan to equip high schools with 'one laptop per child' may go open source. Kevin Rudd's $56 million digital revolution will include 'laptops [that will] run on an open source operating system with a suite of open source applications like those packaged under Edubuntu. This would include Open Office for productivity software, Gimp for picture editing and the Firefox internet browser.' So far this has been considered for New South Wales and I think other states may follow."
