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."

macs4all writes "Apple has finally addressed the Java vulnerability that nearly everyone else patched months ago. Available now for OS X 10.4 and 10.5, and through Apple's Software Update service, this update patches a flaw in the Java Virtual Machine that could potentially allow a malicious Java applet to execute arbitrary code on the machine. Apple had previously advised users to turn off Java temporarily in their Web browsers."

An anonymous reader writes "The Washington Post's Security Fix is reporting that hackers broke into servers at the Virginia health department that monitors prescription drug abuse and replaced the homepage with a ransom demand. The attackers claimed they had deleted the backups, and demanded $10 million for the return of prescription data on more than 8 million Virginians. Virginia isn't saying much about the attacks at the moment, except to acknowledge that they've involved the FBI, and that they've shut down e-mail and a whole mess of servers for the state department of health professionals. The Post piece credits Wikileaks as the source, which has a copy of the ransom note left behind by the attackers."

Norsefire writes "Two economists at Washington University in St. Louis are claiming that copyright and patent laws are 'killing innovation' and 'hurting [the] economy.' Michele Boldrin and David K. Levine state they would like to see copyright law abolished completely as there are other protections available to the creators of 'intellectual property' (a term they describe as 'propaganda,' and of recent origin). They are calling on Congress to grant patents only where an invention has social value, where the patent would not stifle innovation, and where the absence of a patent would damage cost-effectiveness."

eldavojohn writes "Ars brings us news of Amazon's entrance into the casual gaming market after purchasing Reflexive last year. Amazon identifies this sort of gaming as a good start for its demographic of customers and is certainly making competitors in the field nervous. There is a lot of evidence that Amazon is testing the waters to see how these small time games go as a prerequisite to something bigger, although they aren't talking. From Ars, 'For the first week, visitors will even be able to grab three games for free: Jewel Quest 2, Build a Lot, and The Scruffs. That, along with the ability to try every game before you buy, should be enough to entice fans of casual gaming to check out Amazon's offerings. It also looks like this could be Amazon's first step into the world of digital distribution for video games.' Do you think this trial will go well for Amazon?"

jonbryce writes "The Internet Watch Foundation, guardians of the Great Firewall of Britain, have stopped censoring Wikipedia for hosting what they considered to be a child porn image. They had previously threatened to block Amazon for hosting the same image." Here is the IWF's statement, which credits the Streisand Effect for opening their eyes: "...in light of the length of time the image has existed and its wide availability, the decision has been taken to remove this webpage from our list. Any further reported instances of this image which are hosted abroad, will not be added to the list. ... IWF's overriding objective is to minimize the availability of indecent images of children on the internet, however, on this occasion our efforts have had the opposite effect."

joe writes "Aram Harrow and colleagues have just published on the arXiv a quantum algorithm for solving systems of linear equations (paper, PDF). Until now, the only quantum algorithms of practical consequence have been Shor's algorithm for prime factoring, and Feynman-inspired quantum simulation algorithms. All other algorithms either solve problems with no known practical applications, or produce only a polynomial speedup versus classical algorithms. Harrow et. al.'s algorithm provides an exponential speedup over the best-known classical algorithms. Since solving linear equations is such a common task in computational science and engineering, this algorithm makes many more important problems that currently use thousands of hours of CPU time on supercomputers amenable to significant quantum speedup. Now we just need a large-scale quantum computer. Hurry up, guys!"

Khuffie writes "It seems that the upcoming version of Opera 10, of which the first Alpha has recently been released, has already passed the Acid 3 test with a 100/100. The only other rendering engine to have a complete score is WebKit, which can be seen in Google Chrome's nightly build. Opera 10 Alpha 1 will also finally include auto-updates, inline spell checking, and see some improvements to its built-in mail client, including much-requested rich text composition."

An anonymous reader writes "SIFO (a major Swedish survey company) has conducted a gaming survey right before the launch of Dreamhack Winter. One of the results is that gaming is bigger than football and hockey combined."

We made it. It's election day. Tomorrow we'll know. So for today's election discussion story, I'm throwing it wide open: let's discuss the election itself. Who are your picks and why. And also what about your actual experience voting today? Did Diebold eat your vote or did everything go off without flaw?

CNet is reporting that Netflix has opened up its "Watch Instantly" feature to Mac users (here is Netflix's blog entry). They accomplished this by using Microsoft's Silverlight technology on both platforms, abandoning the Windows Media Player solution that had been employed in the first, Windows-only, version. Silverlight's DRM capabilities meet Netflix's needs, apparently. Netflix warns that this is beta software. Mac users can opt in here, then watch instantly with Safari or Firefox 2+, with the Silverlight plugin in place. Movie selection is somewhat limited.
