Replacing Atime With Relatime in the Kernel 416

eldavojohn writes "Our friend Jeremy at the Kernal Trap has dug up some interesting criticism of atime from Linus Torvalds. As Linus submitted patches to improve relatime he noted: 'I cannot over-emphasize how much of a deal it is in practice. Atime updates are by far the biggest IO performance deficiency that Linux has today. Getting rid of atime updates would give us more everyday Linux performance than all the pagecache speedups of the past 10 years, _combined_.' And later severely beat atime about the head with a pointed stick: 'It's also perhaps the most stupid Unix design idea of all times. Unix is really nice and well done, but think about this a bit: 'For every file that is read from the disk, lets do a ... write to the disk! And, for every file that is already cached and which we read from the cache ... do a write to the disk!'" Well, I guess I can expect my Linux machine to become a little bit faster!"

Automatix 'Actively Dangerous' to Ubuntu 284

exeme writes "Ubuntu developer Matthew Garrett has recently analyzed famed Ubuntu illegal software installer Automatix, and found it to be actively dangerous to Ubuntu desktop systems. In a detailed report which only took Garrett a couple of hours he found many serious, show-stopper bugs and concluded that Ubuntu could not officially support Automatix in its current state. Garrett also goes on to say that simple Debian packages could provide all of the functionality of Automatix without any of the problems it exhibits."
AMD

3.0GHz Phenom and 3-Way CrossFire Spotted 103

MojoKid writes "AMD revealed the clock speed of the Agena-based processor they showed to the press today yesterday in conference, and clocks in at 3.0GHz. There has been a lot of speculation that AMD wasn't able to push early Phenom samples to frequencies this high, but here is proof that at least some Phenoms clocked at 3.0GHz do exist. You may also notice that the system hit a Windows Experience index score of 5.9, which is the highest score possible. It should be noted that AMD talked about 4-way CrossFire as well (a 3-way CrossFire is shown online), and that the company has continued plans to produce discreet GPUs at all performance levels (mainstream — enthusiast), even after Fusion arrives."

Submission + - Computer waste fuels toxic trade (itmanagersjournal.com)

nanday writes: "Do you know what happens to your used computer equipment after it has been discarded? The answer may surprise you. Even if you have tried to recycle it, your old hardware often gets shipped to a developing nation in direct violation of international law. Useful components are then extracted — without safety precautions — by locals earning pennies a day and who are exposed to a range of hazardous toxins that include lead, beryllium, mercury, cadmium, and brominated flame retardants. Though slated to be banned over a decade ago, the practice continues and seems to be growing. North America, Japan, and South Korea are among the worst offenders. Solutions exist, and free software is a small part of them, but implementing them remains a painfully slow process."

Wii May Be Succeeding in Widening Game Market 184

superdan2k writes "When Nintendo brought the Wii to market, one of their stated goals was to get people who didn't normally play video games using their console. Based on an article from the AP, it seems they've made some headway in capturing the senior citizen market. With the Wii's price point, and it being a good way to get people engaged in physical exercise, it's easy to envision it catching on with other retirement homes beyond the one mentioned in the article."

Submission + - Wired trying to bury Digg? Or after a good story?

thefickler writes: Bloggers and social news site aficionados are accusing Wired News of trying to damage social news site Digg, after a story appeared on Wired News in which the journalist claimed she bought "diggs" to make her ridiculous story "popular" on Digg.

Wired News is owned by CondéNet, which also owns Digg competitor reddit

A more likely scenario is that Wired was simply after an interesting story...

Submission + - Is Wired Trying to Kill Digg?

ClamIAm writes: "Wired's latest article about Digg is interesting. But with the parent company of Wired also owning reddit, are there hidden motivations behind it? Michael Arrington of TechCrunch thinks so, and suggests that Digg sue Wired. From the article:

Reddit was acquired in late October. By December, Wired had predicted the fall of Digg, saying "Digg Becomes the New Friendster" without disclosing that they were a sister company to a competitor. .... Today Wired takes another, more elaborate shot at Digg. In a piece of investigative journalism, Wired reporter Annalee Newitz used a service called User/Submitter that pays people to Digg a story, which resulted in it getting to the home page of Digg.

Why the iPhone Keynote Was A Mistake 507

jcatcw writes "Mike Elgan at Computerworld lists six reasons why it was a mistake to make the iPhone keynote at Macworld. He argues that extremely high expectations can only lead to disappointment for consumers and investors. The focus on the phone during the keynote also took away from the Apple TV announcement, put iPod sales at risk, gave competitors a head start, and (perhaps worst of all) ruined the company's talks with Cisco over the iPhone name. From the article: 'The iPhone, despite its many media-oriented virtues and its sweet design, will do far less than most existing smart phones. The problem Apple now faces because of Jobs' premature detail-oriented announcement is that of dashed expectations. When customers expect more and don't get it, they become dissatisfied.'"

Microsoft to Launch Zune in EU 220

An anonymous reader writes "Happy with the sales from the little brown music player here in the states, Microsoft is working to launch the Zune media player in Europe by the end of the year. According to the Washington Post article, they are trying to have a realistic outlook on the entrenched Apple product line. They're not trying to play catch-up at the moment ... they're just trying to get on the map. From the article: '"Our next round of introductions will probably be in time for the holiday of this year." [Jason Reindorp] said Microsoft planned extensive research with focus groups in Europe to see how it could be modified for a European consumer. He said the Zune had a 10.2 percent market share in the U.S. in the 30 gigabyte category, according to the latest data, and that it was still in line to sell over a million units by June 30, the end of its current fiscal year.'"

1 Million PlayStation 3s Shipped 234

The word from Gamasutra is that Sony is boasting 1 million PS3s shipped. They hope to have 6 million units out the door by the end of this year. This came from Sony's CES press conference, which only touched briefly on their new system. Hints were, though, that they'll be rolling out an IPTV system for many of their consumer electronics via the Xross GUI already in use on the PSP and PS3. From the article: "According to the company, the majority of new Sony televisions -- starting with several Bravia flat-panel LCD TVs this spring -- will accept an attachable module that can stream broadband high-definition and other Internet video content with the press of a remote control button. The module will be available this summer, and content will come from sources including AOL, Yahoo! and Grouper, now part of Sony Pictures Entertainment, as well as Sony Pictures itself and Sony BMG - however, none of this streaming video content has yet been confirmed for the PlayStation 3."

New iPod Owner Onslaught Overwhelms iTunes 395

Billosaur writes "In the post-Christmas rush to power up and use their new iPods, an onslaught of downloaders brought iTunes to its knees, according to CNN. Monday and Tuesday saw users posting message after message about slow downloads and the iTunes site denying them entry. The heavy traffic was apparently more than the system could bear, what with the large numbers of people receiving iPods and iTunes gift cards. Perhaps Apple was underestimating just how successful they were going to be?"

Small Businesses Worry About MS Anti-Phishing 291

prostoalex writes "Ever get that warm feeling of safety, when the anti-phishing toolbar on Microsoft Internet Explorer 7 turns green, telling you it's safe to shop on the site you're visiting? Well, you probably don't, but the millions of Internet users who will soon be running IE7 probably will be paying attention to the anti-phishing warnings. WSJ.com is reporting on how Microsoft is making it tough for small businesses to assure they're treated properly by the anti-phishing algorithm." From the article: "[S]ole proprietorships, general partnerships and individuals won't be eligible for the new, stricter security certificates that Microsoft requires to display the color. There are about 20.6 million sole proprietorships and general partnerships in the U.S... though it isn't clear how many are engaged in e-commerce... 'Are people going to trust the green more than white? Yes, they will,' says Avivah Litan, an analyst at Gartner Inc. and an expert on online payments and fraud. 'All the business is going to go to the greens, it's kind of obvious.'"

How 'Games for Windows' Will Change PC Gaming 392

Joystiq has a short piece up talking with Windows (GFW) Marketing Director Kevin Unangst and PR Manager Michael Wolf about the future of the 'Games for Windows' initiative. With the launch of Vista, Microsoft is making a big push to turn PC games into a 'console-like' cohesive brand. Instead of relying on the good name of individual publishers to sell titles, Redmond is requiring that all titles use similar packaging and a distinctive logo. Along with the new gamer-centric features in Vista, and the tie-in to Xbox 360 with 'Live Anywhere', this is meant to reinvigorate the PC games market for the sometimes not-so-savvy consumer. From the article: "By making gaming a priority in the Vista experience, Microsoft is molding a powerful pairing of the Games for Windows and Xbox 360 brands. To some extent, this is based on a hope that Live Anywhere will be embraced by GFW developers and publishers, pulling Xbox Live (and your Gamertag) outside of the 'Box, in turn encouraging an unrivaled virtual community. But there are simpler touches that also spark our interest. For example, start up Vista's Minesweeper, connect your 360 controller, and enjoy a subtle rumble each time you slip up. It's the melding with the familiar that will drive new and lost consumers to the Games for Windows brand."

Third Place Is Fine By Nintendo 368

anaesthetica writes "The New Yorker writes that Nintendo is fine with third place. Between Sony and Microsoft both trying to build the most comprehensively next-generation console, and barely breaking even in their efforts [Zonk: Though that's changing for Microsoft], Nintendo has decided to go a different route. Wii doesn't have all the bells and whistles, but it focuses on simple fun playing games — a strategy which turns out to be much better for Nintendo's bottom line and stock prices. From the article: 'A recent survey of the evidence on market share... found that companies that adopt what they call "competitor-oriented objectives" actually end up hurting their own profitability. In other words, the more a company focuses on beating its competitors, rather than on the bottom line, the worse it is likely to do.'"
