GMGruman writes "A bug in Oracle Database that could take down large databases — or let a hacker do so — has been found, and Oracle promises a patch later today. When InfoWorld first heard of the bug two months ago, its investigation revealed how dangerous this bug could be, and after convincing Oracle to address the issue, InfoWorld held the news until a patch was available, so hackers could not exploit the bug in the meantime. Paul Venezia details just how this bug exposes companies to the possibility of databases going offline, and Eric Knorr asks Oracle users to help test the patch in their complex environments. (InfoWorld's tests in simpler environments show the patch works there.)"

New submitter theonlyholle writes "Naked Security, the Sophos IT security blog, has published an article about the authors of the Koobface malware that plagued Facebook users in 2008 and the investigation that led to their identification. Apparently the botnet was created by five Russians from St. Petersburg."

bonch writes "Microsoft has shared details about its new filesystem called ReFS, which stands for Resilient File System. Codenamed 'Protogon,' ReFS will first appear as the storage system for Windows Server and later be offered to Windows clients. Microsoft plans to deprecate lesser-used NTFS features while maintaining 'a high degree of compatibility' for most uses. NTFS has been criticized in the past for its inelegant architecture."

An anonymous reader writes "Following reports of misconduct by Google employees in Kenya and India, It has been found that Google IP addresses have been responsible for deliberate vandalism of OpenStreetMap data. While it is unlikely that this was a deliberate or coordinated attack by Google HQ on the competition, multiple such reports does raise the question of whether or not Google has become too big to effectively enforce its 'Don't be evil' philosophy across its massive organization."

Skuto writes "At yesterdays linux.conf.au Browser miniconference in Ballarat, Australia, Mozilla engineer Nicholas Nethercote gave a detailed presentation about the history of Firefox's memory consumption. The 37 slides-with-notes explain in gritty detail what caused Firefox 4's memory usage to be higher than expected, how many leaks and accidental memory use bugs were tracked down with Valgrind plugins, as well as the pitfalls of common memory allocation strategies. Current work is now focused on reducing the memory usage of popular add-ons such as AdBlock, GreaseMonkey and Firebug. Required reading for people working on large software projects, or those who missed that Firefox is now one of the most memory-efficient browsers in heavy usage."

symbolset writes "Jimmy Wales confirms that the entire English language Wikipedia will be on blackout January 18th from midnight to midnight, Eastern Standard Time. The site's 25 million daily users will redirected to an education page with a call to action. Votes are still being taken on the exact implementation." Despite a small victory against SOPA in the House, Wikipedia still feels the blackout is necessary due to the looming Senate vote on PROTECT IP, and as a deterrent to future attempts to revive a similar law under a new name.

Timothy Lord caught up with Raspberry Pi product leader Eben Upton at CES. The long-awaited $25 Linux single-board computers are finally being shipped from the Chinese factory where they're being assembled and will be available for sale in just a few weeks. Eben talks not only about the Raspberry Pi boards and the add-on Gertboard, but about the eBay auction that helped finance Raspberry Pi. Timothy says he considers Eben Upton one of his "personal tech-world heroes." After watching this video, maybe he'll be one of yours, too. Read on below to watch.

An anonymous reader writes "'The U.S. government just concluded a consultation on whether it should support Canada's entry into the Trans Pacific Partnership negotiations.' The TPP raises significant concerns about extension of copyright and digital locks, so that might be a good thing. However, Michael Geist reports that the IIPA, which represents the major movie, music, and software lobby associations, sees this as an opportunity to force Canada to enact a Canadian DMCA and to implement ACTA."

Hugh Pickens writes writes "Andrei Chikatilo, 'The Butcher of Rostov,' was one of the most prolific serial killers in modern history committing at least 52 murders between 1978 and 1990 before he was caught, tried, and executed. The pattern of his murders, though, was irregular with long periods of no activity, interrupted by several murders within a short period of time. Hoping to gain insight into serial killings to prevent similar murders, Mikhail Simkin and Vwani Roychowdhury at UCLA built a mathematical model of the time pattern of the activity of Chikatilo and found the distribution of the intervals between murders follows a power law with the exponent of 1.4. The basis of their analysis is the hypothesis that 'similar to epileptic seizures, the psychotic affects, causing a serial killer to commit murder, arise from simultaneous firing of large number of neurons in the brain.' In modeling the behavior the authors didn't find that 'the killer commits murder right at the moment when neural excitation reaches a certain threshold. He needs time to plan and prepare his crime' so they built delay into their model. The killings eventually have a sedative effect, pushing the neuronal activity below the 'killing threshold' – which is why there are large intervals of time between groups of murders. 'There is at least qualitative agreement between theory and observation [PDF],' conclude the authors. 'Stats can't tell you who the perp is, but they're getting better and better at figuring out where and when the next crime might happen,' writes criminal lawyer Nathaniel Burney adding that 'catching a serial killer by focusing resources based on when and where he's likely to strike next is a hell of a lot better than relying on the junk science of behavioral profiling.'"

An anonymous reader writes "Facebook and Google told the Delhi High Court today they cannot block offensive content that appears on their services. The two Internet giants are among 21 companies that have been asked to develop a mechanism to block objectionable material in India, and the Indian government has given the green light for their prosecution. Although India is democratic (in fact, it's the world's largest democracy), many fear the country will resort to censorship."

mikejuk writes with an excerpt from an article at i-programmer about a neat graphics demo written in Dart: "One of the difficulties in getting a new computer language accepted by a wider audience is that there is doubt that it is real. Is it a toy language that just proves a concept or can it do real work? In the case of Dart, which is Google's replacement for JavaScript, the development is speeding ahead at a rate that is impressive but worrying. To prove that Dart is already a language that can be used, we now have a port of the well known 2D physics engine Box2D, the one Angry Birds uses, to Dart." Box2D has previously been ported to Javascript. Source is available at Google Code (under the Apache license). Note that you'll need Chromium to run the demos.
