Toyota To Let People Ride In Self-Driving Prius 282

fergus07 writes "Toyota is to show an autonomous Prius at Tokyo Motor Show. Dubbed the Toyota AVOS (Automatic Vehicle Operation System), the car will be available for members of the public to take 'back seat' rides at the show, demonstrating first hand how the Prius can avoid obstacles, be summoned from a parking garage and park itself."

Garbage Collection Algorithms Coming For SSDs 156

MojoKid writes "A common concern with the current crop of Solid State Drives is the performance penalty associated with block-rewriting. Flash memory is comprised of cells that usually contain 4KB pages that are arranged in blocks of 512KB. When a cell is unused, data can be written to it relatively quickly. But if a cell already contains some data, even if it fills only a single page in the block, the entire block must be re-written. This means that whatever data is already present in the block must be read, then it must be combined or replaced, and the entire block is then re-written. This process takes much longer than simply writing data straight to an empty block. This isn't a concern on fresh, new SSDs, but over time, as files are written, moved, deleted, or replaced, many blocks are a left holding what is essentially orphaned or garbage data, and their long-term performance degrades because of it. To mitigate this problem, virtually all SSD manufacturers have incorporated, or soon will incorporate, garbage collection schemes into their SSD firmware which actively seek out and remove the garbage data. OCZ, in combination with Indilinx, is poised to release new firmware for their entire line-up of Vertex Series SSDs that performs active garbage collection while the drives are idle, in order to restore performance to like-new condition, even on a severely 'dirtied' drive."

Extinct Pyrenean Ibex Cloned 249

jamie points out a story in the Telegraph about a project to clone the Pyrenean Ibex (known also as bucardo), a species that went extinct in 2000. Before the last known member of the species died, scientists took tissue samples to begin a project to clone the animal. "Using techniques similar to those used to clone Dolly the sheep, known as nuclear transfer, the researchers were able to transplant DNA from the tissue into eggs taken from domestic goats to create 439 embryos, of which 57 were implanted into surrogate females. " Now, for the first time, one of them has survived the gestation period, living for seven minutes after birth. One of the researchers said, "The delivered kid was genetically identical to the bucardo. In species such as bucardo, cloning is the only possibility to avoid its complete disappearance."
