New research suggests that in addition to being one of history's cruelest conquerors, Genghis Khan may have been the greenest. It is estimated that the Mongol leader's invasions unintentionally scrubbed almost 700 million tons of carbon from the atmosphere. From the article: "Over the course of the century and a half run of the Mongol Empire, about 22 percent of the world's total land area had been conquered and an estimated 40 million people were slaughtered by the horse-driven, bow-wielding hordes. Depopulation over such a large swathe of land meant that countless numbers of cultivated fields eventually returned to forests. In other words, one effect of Genghis Khan's unrelenting invasion was widespread reforestation, and the re-growth of those forests meant that more carbon could be absorbed from the atmosphere." I guess everyone has their good points.

'Game publisher and miniature manufacturer Games Workshop just sent a cease and desist letter to boardgamegeek.com, telling them to remove all fan-made players' aids. This includes scenarios, rules summaries, inventory manifests, scans to help replace worn pieces — many of these created for long out of print, well-loved games...' As a lifelong hobby gamer of table, board, card and miniature games, I view this as pure heresy. It made me reject the idea of buying any Games Workshop (read Warhammer) products for my son this Christmas. Their fate was sealed, in terms of my wallet, after I Googled their shenanigans. In 2007 they forbid Warhammer fan films, this year they shut down Vassal Modules, and a while back they went after retailers as well. What ever happened to fair use?"

An anonymous reader writes "According to Australia's Office of Film and Literature Classification, Left 4 Dead 2's content exceeds that allowable for an MA15+ rating. Any such game is rated as Refused Classification, effectively banning it. From the report: 'The game contains realistic, frenetic, and unrelenting violence which is inflicted upon "the Infected" who are living humans infected with a rabies-like virus that causes them to act violently. The player can choose from a variety of weapons including pistols, shotguns, machine guns, and sniper rifles. However, it is the use of the "melee" weapons such as the crowbar, axe, chainsaw and Samurai sword which inflict the most damage. These close-in attacks cause copious amounts of blood spray and splatter, decapitations and limb dismemberment as well as locational damage where contact is made to the enemy which may reveal skeletal bits and gore.'"

Barence writes "Since writing about the success he's had with powerline networking, a number of readers emailed PC Pro's Paul Ockendon to castigate him for recommending these products, such as HomePlug. They were all amateur radio enthusiasts, claiming the products affect their hobby in much the same way that urban lighting affects amateur astronomers, but rather than causing light pollution they claim powerline networking causes radio pollution in the HF band (otherwise known as shortwave). Paul's follow-up feature, 'Does powerline networking nuke radio hams?' documents his investigation into these claims, which found evidence to support both sides of an intriguing debate."

Voyager529 writes "While virtually every Core 2 Duo processor supports the hardware virtualization technology that powers the Windows 7 XP Mode, The Register UK reports that the Core 2 Duo processors in the Sony Vaio Z series laptops had the virtualization features intentionally crippled in the BIOS. Senior manager for product marketing Xavier Lauwaert stated that the QA engineers did this to make the systems more resilient against malicious code. He also stated that while they are considering enabling VT in some laptop models due to the backlash, the Z series are not among those being retrofitted."
