Hack knocks out a fifth of the Dark Web—Engadget, Jon Fingas Top line: “An Anonymous-linked hacker speaking to Motherboard brought down about a fifth of the Tor network’s ‘secret’ websites (over 10,000 of them) in a claimed vigilante move. The intruder decided to attack a Dark Web hosting service, Freedom Hosting II, after discovering that it was managing child porn sites it had to be aware of — they were using gigabytes of data each when the host officially allows no more than 256MB. Each site had its usual pages replaced with a message that not only chastised FH2, but offered a data dump (minus user info) and explained the nature of the hack.” Topics to follow: Hacking, Anonymous 7.

Lady Gaga’s Halftime Show Drones Have a Bright Future—Wired, Brian Barrett Top line: “Preparations kicked off in early December, when Intel’s engineers started wading into the mind-numbing logistics of choreographing 300 dancing drones. Do they fly inside the stadium? How are they integrated into what Lady Gaga is doing onstage? Is the stadium’s domed roof open or closed? ‘The whole halftime is a huge execution monster of an exercise,’ says Anil Nanduri, who leads Intel’s drone efforts.” Topics to follow: Lady Gaga, Super Bowl, Intel ~LindseyW is reading Space
