Comment: Resolution is not the hard-to-solve problem.. (Score 4, Informative) 135

Display resolution is not the hard-to-solve problem. This quote from John Carmack sums it up best:

The latency between the physical movement of a users head and updated photons from a head mounted display reaching their eyes is one of the most critical factors in providing a high quality experience. Human sensory systems can detect very small relative delays in parts of the visual or, especially, audio fields, but when absolute delays are below approximately 20 milliseconds they are generally imperceptible.

According to the article

[...]the latest GameFace SDK significantly reduces latency to a point that it is easily comparable to the DK1. The company plans to benchmnark their latency soon to get a quantitative latency figure.

Notice that is DK1 latency, not DK2. DK1's latency was notoriously bad and made many people nauseous. So, while I'm happy to see competition in this space, as far as GameFace is concerned, there is not a lot to see here yet.

Comment: 640x400 per eye. (Score 1) 93

The Oculus is 640x400 per eye for a total of 1280x800. Not 1280x800 per eye. I've no idea why the total resolution is always mentioned since it's a completely useless metric. I think they've solved a lot of hard problems with this device -- in particular head tracking lag -- but it still has some baking to do before it's ready for your average gamer to use as a monitor replacement. In particular the resolution needs to approach or surpass 720p. Can someone more familiar with HDMI comment on the viability of pushing 2 720p signals @ 60Hz over HDMI? I know it's an issue for 1080p, not sure about 720p.

Security Camp Is Not Space Camp, Just Based On It (Video) 38

Posted by Roblimo
from the way-better-than-spending-summer-watching-TV dept.
The idea behind the United States Space Camp is to give kids (and some adults) a chance to do astronaut training-type things that will get them jazzed on science and technology, in addition to getting away from home for a while. Security Camp is sort of like that that, says instigator Marc Tobias, but is about security stuff rather than space, and somehow interviewer Timothy Lord didn't ask Tobias about plans to teach security, computer or otherwise, for space travelers, when he talked with Tobias at HOPE (Hackers on Planet Earth) in New York. Since Tobias is an expert in physical security (locks), and locksmithing is going to be taught at Security Camp along with electronic/hacking-type security skills, it's a good thing all participants will be checked for criminal records and tendencies before they're allowed to participate. If there are plans to make a movie about Security Camp, which Tobias didn't mention one way or the other during this interview, we hope it's better than the 1986 movie, Space Camp.

For me, the quality of slashdot has been declining, for years really. It still presents a lot of great stuff, but more and more I find myself annoyed by
  • non-tech articles
  • articles that no one here cares about but that get posted over and over anyway because someone at slashdot has a vested interest (bitcoin)
  • politics being inserted into articles
  • poorly reviewed articles that either purposefully sensationalize the headline or get the summary completely wrong
  • and now infomercials

I really enjoy slashdot because there are a lot of intelligent, well-spoken people here, but I'm so close to being done with it. Makes me a little sad.

Just to be clear, the original plant that started the cloning process was not 200,000 years old. According to TFA it was between 12,000 and 200,000.

Honestly /., if you are going to use questionable scientific articles from the Telegraph, can you at least not make it more sensationalist by purposefully misquoting the age of the plant?

Vista Security — Too Little Too Late 483

Posted by kdawson
from the five-years-work dept.

Thomas Greene of The Register has a fairly comprehensive review of Vista and IE7 user security measures. The verdict is: better but not adequate, and mostly an attempt to shift blame onto the user when things go wrong. From the review: "[Vista is] a slightly more secure version than XP SP2. There are good features, and there are good ideas, but they've been implemented badly. The old problems never go away: too many networking services enabled by default; too many owners running their boxes as admins and downloading every bit of malware they can get their hands on."

"Very Severe Hole" In Vista UAC Design 813

Posted by kdawson
from the she-said-he-said dept.
Cuts and bruises writes "Hacker Joanna Rutkowska has flagged a "very severe hole" in the design of Windows Vista's User Account Controls (UAC) feature. The issue is that Vista automatically assumes that all setup programs (application installers) should be run with administrator privileges — and gives the user no option to let them run without elevated privileges. This means that a freeware Tetris installer would be allowed to load kernel drivers. Microsoft's Mark Russinovich acknowledges the risk factor but says it was a 'design choice' to balance security with ease of use."

Vista Not Playing Nice With FPS Games 437

from the shoot-em-up dept.
PetManimal writes "Computerworld is reporting that gamers who have installed Vista are reporting problems with first person-shooter titles such as CounterStrike, Half-Life 2, Doom 3. and F.E.A.R. (Users have compiled lists of games with Vista issues.) The complaints, which have turned up on gamers' forums, cite crashes and low frame rates. Not surprisingly, the problems relate to graphics hardware and software: 'Experts blame still-flaky software drivers, Vista's complexity, and a dearth of new video cards optimized for Vista's new rendering technology, DirectX 10. That's despite promises from Microsoft that Vista is backwards-compatible with XP's graphic engine, DirectX 9, and that it will support existing games. Meanwhile, games written to take advantage of DirectX 10 have been slow to emerge. And one Nvidia executive predicts that gamers may not routinely see games optimized for DirectX 10 until mid-2008.'"

Windows Expert Jumps Ship 939

from the hello-apple dept.
An anonymous reader writes to let us know that Scott Finnie, Computerworld's Windows expert, has given the final verdict to Windows after 3 months of using a Mac. And the verdict is: "Sayonara." Finnie is known to readers here for his many reviews of Vista as it progressed to release. Quoting: "If you give the Mac three months, as I did, you won't go back either. The hardest part is paying for it — everything after that gets easier and easier. Perhaps fittingly, it took me the full three-month trial period to pay off my expensive MacBook Pro. But the darn thing is worth every penny."

Bitlocker No Real Threat To Decryption? 319

Posted by Zonk
from the keep-this-under-your-hat dept.
An anonymous reader writes "The Register is running a story called 'Vista encryption 'no threat' to computer forensics'. The article explains that despite some initial concerns that lawbreakers would benefit from built-in strong encryption, it's unlikely the Bitlocker technology will slow down most digital forensic analysts. What kind of measures does one need to take to make sure no one but yourself has access to your data? Is Bitlocker just good enough (keeping out your siblings) or does it miss the whole purpose of the encryption entirely?" One would hope an international criminal mastermind could do better than the encryption built into Vista.

Vista Indicates A Shift in Microsoft's Priorities 499

Posted by Zonk
from the end-users-at-the-end dept.
jcatcw writes "After hundreds of hours of testing Vista, Scot Finnie is supremely tired of it. And of Microsoft. Although 80% of the changes in Windows Vista are positive, there is nothing about Vista that is truly innovative or compelling; there's no transformational, gotta-have-it feature in Vista. But the real problem isn't with Vista. It's with Microsoft itself. His opinion is that Microsoft has stopped focusing on end users. They 'now seemingly make many decisions based on these two things: 1. Avoiding negative publicity (especially about security and software quality) 2. Making sure the largest enterprise customers are happy.'"

Koreans Advised to "Avoid Vista" for Now 333

from the as-long-as-warcrack-still-works dept.
An anonymous reader writes "The Chosonilbo reports that several government ministries in South Korea are advising users not to install Windows Vista, at least until popular online services can be made compatible. The problem is that ActiveX is pervasive in the Korean webspace, employed by everyone from web games to online banking. Upgrading to Vista is expected to render many of these services unusable. Portions of the popular "Hangul" word processor, a major competitor to Office in that country, are also not functioning under Vista. The Ministry of Information is planning to publish compatibility information for popular websites, and urging users to carefully research the implications of upgrading."
