Submission + - How Often Does Your Car Really Need an Oil Change?

Hugh Pickens writes writes: "The LA Times reports that quick-lube companies have done such a good job convincing consumers that they need to change the oil in their cars every 3,000 miles that drivers are wasting millions of gallons of oil annually because they have their vehicles serviced too often as improvement in oils, friction proofing and car engines have lengthened the oil-change interval, typically 7,500 miles to 10,000 miles for most vehicles. "Our survey data found that nearly half of California drivers are still changing their oil at 3,000 miles or even sooner," says Mark Oldfield, a spokesman for the California Department of Resources, Recycling and Recovery, which has launched a website, checkyournumber.org, where drivers can look up the suggested motor-oil change interval number for their vehicles. Ford Motor Co. recommends oil changes for most of its new vehicles at 10,000 miles, although some still require the service at 7,500 miles. "Our new generation of engines have tighter internal tolerances, which reduces the amount of carbon and other products from combustion that gets into the oil," says Richard Truett, a Ford spokesman. Both Honda and Acura are equipped with a maintenance minder system that recommends oil changes and other services based on a number of vehicle-usage factors, including mileage and climate and other manufacturers have similar systems that alert drivers to the need for an oil change. "The idea is to prevent either over- or under-maintaining a car by following a set schedule," says Chris Martin, a Honda spokesman. "Now, there is no guesswork.""

Submission + - JPMorgan Rolls Out (Another) FPGA Supercomputer (computerworlduk.com)

An anonymous reader writes: JP Morgan is expanding its use of dataflow supercomputers to speed up more of its fixed income trading operations. Earlier this year, the bank revealed how it reduced the time it took to run an end-of-day risk calculation from eight hours down to just 238 seconds. The new dataflow supercomputer, where the computer chips are tailored to perform specific, bespoke tasks (as explained in this Wall Street Journal article) — will be equivalent to more than 12,000 conventional x86 cores, providing 128 Teraflops of performance.

Submission + - Video Analytics Opportunities Abound (smartertechnology.com)

An anonymous reader writes: Any programmers out there with expertise in the pattern recognition and motion processing algorithms which come under the rubric 'video analytics' would do well to bone up. The video analytics business is becoming a billion dollar market. In addition to the legions of algorithms needed for security and safety, everything from pinpointing available parking spaces for drivers to counting attendees at the latest 'occupy' rally are fair game.

Submission + - Nightingale Media Player Preview Released (getnightingale.com)

ilikenwf writes: "You may or may not remember the Mozilla-based Songbird media player, which dropped official Linux support in April, 2010. Since then, the Nightingale community fork has waxed and waned in terms of membership and progress, but thanks to having a completely new dev team has today produced a preview build based on Songbird 1.8.1. The team promises a release of a Songbird trunk based build later this year, with fixes and an upgrade to Gecko 6. Plans to support Linux, Windows, and Mac are in the works, with the preview builds being available only for Linux and Windows at the moment. Aside from trying to pull in refugees from the Songbird community, Nightingale wants more developers to aid in fixing dropped and broken features from Songbird — and to add new ones."

Submission + - Google Wallet Stores Card Data In Plain Text (darkreading.com)

nut writes: The much-hyped payment application from Google on Android has been examined by viaForensics and appears to store some cardholder data in plaintext. Google wallet is the first real payment system to use NFC on Android. Version 2 of the PCI DSS (the current standard) mandates the encryption of transmitted cardholder data encourages strong encryption for its storage. viaForensics suggest that the data stored in plain text might be sufficient to allow social engineering to obtain a credit card number.

Submission + - Hubble pic of a 30 octillion ton baby's tantrum (hubblesite.org) 2

The Bad Astronomer writes: "In what is one of the most staggeringly beautiful Hubble pictures ever taken, a newly-born massive star is blasting four separate jets of material into its surrounding cocoon, carving out cavities in the material over two light years long. But only three of the jets appear to have matter still inside them, and the central star is off-center. This may be a gorgeous picture, but the science behind it is equally as compelling."

>The question is whether you will be able to take an existing Win32 app, and recompile it for Win8/ARM.

I think we're having a semantic issue. What I consider a windows desktop is what we currently see as a windows desktop, with all of the ability to run windows executable, legacy or new (which is how the windows desktop has always been).

If you consider the "desktop" as being able to run anything, then looking at how they've handles windows phone unlocking, it appears they don't have any problems with people running non-signed/app store apps on ARM platforms (assuming you're willing to download some "I want out of the sandbox" "jailbreak" from the app store).

My point is that they'll never put a current looking or functioning windows desktop on the arm.

Well, that and the fact that an desktop on the arm would require x86 emulation for 99% of the existing applications.

They will *never* make it appear as a standard desktop because of this. People will pick it up and say "absolutely none of my software works on this". They'll come out with something that, technically, is a desktop, but has no resemblance to the standard desktop (meaning no indication to the user that 99% of the programs aren't compatible"). Oh wait, that's what metro is...a sandboxed cross platform desktop.

Comment Re:doubt it (Score 5, Insightful) 389

Nobody will be forcing anyone to use metro or buy any of the walled garden metro apps. It's just a program that lets you run the sandboxed metro apps. Close it or boot into the standard desktop. Most metro apps will support windows mobile devices and the desktop.

To the vast majority of users that download and try all the free apps they can click on and who don't know or care about any of this, being able to fix a "my phone is infected and doesn't work!" type scenarios is absolutely a feature.

Also, I doubt any os provider will want to be in the spotlight for causing mass network outages after some trojan decides to activate on 100,000 phones, with no way to stop it.
