PHP Floating Point Bug Crashes Servers 213

Posted by timothy on Thursday January 06, 2011 @02:55PM from the inexactly-wrong dept.

angry tapir writes "A newly unearthed bug in certain versions of the PHP scripting language could crash servers when the software is given the task of converting a large floating point number, raising the possibility that the glitch could be exploited by hackers. The bug will cause the PHP processing software to enter an infinite loop when it tries to convert the series of digits "2.2250738585072011e-308" from the string format into the floating point format. The bug only seems to affect version 5.2 and 5.3 of the language." Adds reader alphadogg: "Computer scientist Rick Regan first reported the bug on Monday, and the PHP development team issued patches the following day."

Smartphones For Text SSH Use Re-Revisited 359

Posted by CmdrTaco on Thursday January 06, 2011 @10:33AM from the serious-business dept.

Kainaw writes "This was asked in 2005 and 2008. I think it should be revisited yet again... With iPhone, Android, and Windows smartphones running around, which (if any) of them are well-suited to Unix/Linux server administration on the run? SSH is a must. A good screen resolution. A physical keyboard won't block the screen with a virtual keyboard. Many physical keyboards omit the numeric keys now, making the typing of numbers rather difficult. Nearly every smartphone has WiFi capability now. Some will do an X display through SSH tunnelling. So, pushing through all the bells and whistles that have nothing to do with effective server administration, what is left?"

Why Creators Should Never Read Their Forums 221

Posted by Soulskill on Thursday January 06, 2011 @03:52AM from the lalala-i-can't-hear-you dept.

spidweb writes "One full-time Indie developer writes about why he never goes to online forums discussing his work and why he advises other creators to do the same. It's possible to learn valuable things, but the time and the stress just don't justify the effort. From the article, 'Forums contain a cacophony of people telling you to do diametrically opposite things, very loudly, often for bad reasons. There will be plenty of good ideas, but picking them out from the bad ones is unreliable and a lot of work. If you try to make too many people happy at once, you will drive yourself mad. You have to be very, very careful who you let into your head.'"

IBM's Jeopardy Strategy 99

Posted by samzenpus on Wednesday January 05, 2011 @04:37PM from the john-henry dept.

jfruhlinger writes "Developing a computer that could play chess once seemed like a worthy AI goal — but it turned out to be something of a dead end, as chess is very abstract and simple when compared to the real world. Will creating a game-show-playing computer lead to more interesting results? IBM hopes so, and its Watson machine will tackle problems in parallel processing, data searching, and natural language comprehension in an attempt to beat Jeopardy legends Ken Jennings and Brad Rutter. " IBM announced the man vs. machine competition last month.

Samsung Develops Power-Sipping DDR4 Memory 152

Posted by timothy on Wednesday January 05, 2011 @03:11AM from the continue-to-enjoy-the-treadmill dept.

Alex writes with this excerpt from TechSpot: "Samsung Electronics has announced that it completed development of the industry's first DDR4 DRAM module last month, using 30nm class process technology, and provided 1.2V 2GB DDR4 unbuffered dual in-line memory modules (UDIMM) to a controller maker for testing. The new DDR4 DRAM module can achieve data transfer rates of 2.133Gbps at 1.2V, compared to 1.35V and 1.5V DDR3 DRAM at an equivalent 30nm-class process technology, with speeds of up to 1.6Gbps. In a notebook, the DDR4 module reduces power consumption by 40 percent compared to a 1.5V DDR3 module. The module makes use of Pseudo Open Drain (POD) technology, which allows DDR4 DRAM to consume just half the electric current of DDR3 when reading and writing data."

Reverse Engineering Doctor Who Into Color 171

Posted by timothy on Wednesday January 05, 2011 @12:09AM from the like-time-travel-for-real dept.

Lanxon writes "In 1967, the BBC set about junking its Doctor Who archive: a moment sci-fi fans wish they could travel back in time to prevent. There are 108 vintage episodes missing, but since 1978 a number have been rediscovered as 16mm black-and-white films. The BBC shot many of these series in color, but made monochrome copies for countries such as Australia, where many TV companies were still broadcasting in greyscale. The reels had sat in archives since. Now, the Doctor Who Restoration Team, an independent group contracted by the BBC, is using a new technique to regenerate The Doctor in color."

Honeycomb To Require Dual-Core Processor 177

Posted by timothy on Tuesday January 04, 2011 @10:56PM from the expand-the-requirements dept.

adeelarshad82 writes "According to managing director of Korean consumer electronics firm Enspert, Google's new Android Honeycomb tablet OS will require a dual-core ARM Cortex-A9 processor to run properly. That means that many existing Android tablets will not be upgradeable to Honeycomb, as they lack the processor necessary to meet the spec. Currently, Nvidia's Tegra 2 platform is the only chipset in products on the market to include a Cortex-A9, although other manufacturers have said they're moving to the new processor architecture for 2011 products."

The Care and Feeding of the Android GPU 307

Posted by CmdrTaco on Tuesday January 04, 2011 @03:05PM from the eet-mor-hooman dept.

bonch writes "Charles Ying argues that Android's UX architecture has serious technical issues because, unlike the iPhone and Windows 7, Android composites the interface in software to retain compatibility with lower-class devices. Additionally, Android runs Java bytecode during animation, and garbage collection blocks the drawing system. Google engineers dismiss the desire for hardware-accelerated compositing and cite more powerful hardware and an avoidance of temporary objects as a solution to the collection pauses, but Ying argues that will just lead to [a lower] average battery life compared to devices like the iPhone."

Researchers Claim 1,000 Core Chip Created 118

Posted by CmdrTaco on Monday January 03, 2011 @02:12PM from the eat-the-seeds dept.

eldavojohn writes "Remember a few months ago when the feasibility was discussed of a thousand core processor? By using FPGAs, Glasgow University researchers have claimed a proof of concept 1,000 core chip that they demonstrated running an MPEG algorithm at a speed of 5Gbps. From one of the researchers: 'This is very early proof-of-concept work where we're trying to demonstrate a convenient way to program FPGAs so that their potential to provide very fast processing power could be used much more widely in future computing and electronics. While many existing technologies currently make use of FPGAs, including plasma and LCD televisions and computer network routers, their use in standard desktop computers is limited. However, we are already seeing some microchips which combine traditional CPUs with FPGA chips being announced by developers, including Intel and ARM. I believe these kinds of processors will only become more common and help to speed up computers even further over the next few years.'"

Does Windows Phone 7 Have a Data Transmission Bug? 202

Posted by CmdrTaco on Monday January 03, 2011 @12:48PM from the that's-a-lotta-bits dept.

blarkon writes "Microsoft commentator and Windows Phone 7 Expert Paul Thurrott has reported a serious bug that indicates Windows Phone 7 is uploading up to 50 MB of unidentified data every day. The phone operating system apparently ignores Wi-Fi connections for sending this data, leading some Windows Phone 7 owners hitting their 2 GB plan data limit while doing little more than checking email and social networking sites. Thurrott has written a book on Windows Phone 7 and is unlikely to be making such a claim unless it has some substance. At the moment no one knows what this data contains or where it is going, though Thurrott suspects it may be related to the Windows Phone Marketplace."

MS Asks Google To Delay Fuzzer Tool 205

Posted by CmdrTaco on Monday January 03, 2011 @12:00PM from the i-need-somebody dept.

eldavojohn writes "Polish Google security white hat Michal Zalewski has announced concerns that one of a hundred vulnerabilities his fuzzer tool found in IE is well known to third party hackers in China. His simple explanation provides an interesting counter argument to Microsoft's usual request that security problems not be released until they can slowly investigate them. From the article, 'Microsoft asked Zalewski to delay cross_fuzz's release, but he declined, in part because of his fear the IE vulnerability was already being explored by Chinese hackers, but also because the company's security experts had not responded to information he provided.' You can read about and download cross_fuzz for your own use."

Wikipedia Meets $16M Budget Goal 255

Posted by CmdrTaco on Monday January 03, 2011 @10:32AM from the burn-that-portrait dept.

netbuzz writes "Thanks to some 630,000 individual contributions that averaged $22 apiece, Wikipedia has reached its fundraising goal of $16 million, founder Jimmy Wales announced over the weekend. Writes Wales, '... this year is a little more incredible than most because this year we celebrate Wikipedia's tenth anniversary. It's so important that we kick the year off just like this: by fully funding the Wikimedia Foundation's budget to support Wikipedia and all the sister projects as we head into the next decade of our work together.' The online encyclopedia now boasts of being the Internet's fifth largest site, which renews questioning by some as to whether it can afford over the long haul to stand by its policy of refusing advertising."

Intel Sandy Bridge Desktop and Mobile CPUs 116

Posted by CmdrTaco on Monday January 03, 2011 @09:44AM from the touch-the-future dept.

Vigile writes "The new Intel Sandy Bridge architecture is being launched at CES this week but the reviews and benchmarks are out today. PC Perspective took a look at both the desktop and mobile variants, the former of which turns out to be quite an impressive processor for both highly threaded and single threaded applications. With some tweaks to the execution unit, a new Turbo Boost mode that increases clock speeds dynamically and a vastly improved integrated graphics implementation, the Core i7-2600K improves in every aspect. Also interestingly, the most expensive desktop part will start at $317, putting the screws to AMD yet again. On the mobile side of things, PC Perspective tested the quad-core Core i7-2820QM and the benchmark results are equally impressive; especially when looking at the gaming performance using integrated graphics. Sandy Bridge will no doubt put quite a dent in the discrete notebook graphics market for NVIDIA and AMD."
