Apple-1 Sells For $671,400, Breaks Previous Auction Record
Sun, 26 May 2013 06:17:00
hypnosec writes "What is believed to be one of the six working Apple-1 computers has fetched a whopping $671,400 for its current owner at an auction in Germany. The Apple-1 was built by Steve Wozniak back in 1976 in the garage of Steve Jobs' parents. The model sold at auction is either from the first lot of 50 systems ordered by Paul Terrell, owner of the Byte Shop chain of stores, or part of the next lot of 150 systems the duo built to sell to friends and vendors. The retail price for the Apple-1 at the time was $666.66."

ARM In Supercomputers — 'Get Ready For the Change'
Sun, 26 May 2013 03:10:00
An anonymous reader writes "Commodity ARM CPUs are poised to to replace x86 CPUs in modern supercomputers just as commodity x86 CPUs replaced vector CPUs in early supercomputers. An analysis by the EU Mountblanc Project (PDF) (using Nvidia Tegra 2/3, Samsung Exynos 5 & Intel Core i7 CPUs) highlights the suitability and energy efficiency of ARM-based solutions. They finish off by saying, 'Current limitations [are] due to target market condition — not real technological challenges. ... A whole set of ARM server chips is coming — solving most of the limitations identified.'"

Researcher Unlocks Galaxy S4 Bootloader For AT&T, Verizon Phones
Sun, 26 May 2013 00:02:00
Trailrunner7 writes "Those of you who like to tinker and jailbreak Android phones should take notice of some new research conducted on Samsung Galaxy S4 Android devices shipped by AT&T and Verizon. Both devicemakers ship the Galaxy S4 smartphones with a locked-down bootloader that prevents users from uploading custom kernels or from making modifications to software on the phone. Azimuth Security researcher Dan Rosenberg has found a vulnerability in the manner in which the devices do cryptographic checks of boot image signatures and was able to exploit the flaw and upload his own unsigned kernel to the device."

Mayor Bloomberg Battles Fleet Owners Over NYC 'Taxi of Tomorrow'
Sat, 25 May 2013 23:00:00
An anonymous reader writes "In April, Mayor Mike Bloomberg announced that the Nissan NV200 minivan had won a citywide competition to replace the current cab model, the Ford Crown Victoria, in a phased-in period of five years. Cab owners sued, pointing out that New York City law requires that hybrid electric models be available for immediate use for cab medallion owners; that excludes the current Nissan NV200, with its 2.0 liter, 4-cylinder engine rated at a combined 24 mpg. The NV200 also has poor accessibility for wheelchair users. After a state judge blocked the mayor's plan, Bloomberg allegedly told the CEO of Taxi Club Management at a private club, 'Come January 1st, when I am out of office, I am going to destroy your f--king industry.' Tim Fernholz of Quartz speculates that Bloomberg (a billionaire) may be planning to launch a cab-hailing service like Uber, which was just allowed back onto the streets of New York, with significant limitations."

Schrödinger's Cat and RCU (Well, Structured Procrastination, Actually)
Sat, 25 May 2013 21:58:00
davecb writes "Paul E. McKenney, one of the Linux RCU implementors, addresses the problem of synchronization using structured deferral on, what else, Mr Schrödinger's famous cat. Courtesy of deferral/procrastination, the cat can be both alive and dead at the same time. 'In this example, Schrödinger would like to construct an in-memory database to keep track of the animals in his zoo. Births would of course result in insertions into this database, while deaths would result in deletions. The database is also queried by those interested in the health and welfare of Schrödinger's animals. Schrödinger has numerous short-lived animals such as mice, resulting in high update rates. In addition, there is a surprising level of interest in the health of Schrödinger's cat, so much so that Schrödinger sometimes wonders whether his mice are responsible for most of these queries. Regardless of their source, the database must handle the large volume of cat-related queries without suffering from excessive levels of contention. Both accesses and updates are typically quite short, involving accessing or mutating an in-memory data structure, and therefore synchronization overhead cannot be ignored.'"
