dartttt writes with an excerpt from Ubuntu Vibes: "Skeltrack is a Free Software (GPL3) library by Igalia for tracking the human skeleton joints from depth images. It is implemented with GLib and uses plain mathematics to detect the human skeleton and although it does not use any database, it was inspired by Andreas Baak's paper: "A Data-Driven Approach for Real-Time Full Body Pose Reconstruction from a Depth Camera" Skeltrack devs have recorded very cool videos showing Gnome Shell and Linux games being controlled through gestures."
Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."
Election officials in northern Chicago want to know why voter registration material was sent to Princess, a dead goldfish. "I am just stunned at the level of people compromising the integrity of the voting process," said Lake County Clerk Willard Helander, a Republican, who said she has spotted problems with nearly 1,000 voter registrations this year. Beth Nudelman, who owned Princess, said the fish may have got on a mailing list because the family once filled in her name when they got a second phone line for a computer. When will we recognize a goldfish's right to vote?
