Comment Re:Software using OpenGL (Score 1) 88

I believe you meant to reply to the post above me? I was arguing the same thing as you. Development for the Playstation, apparently can use either their own GCM library or an OpenGL ES compatible api called psGL... so that would be another exception in addition to Apple's Metal api.

Sorry for that obvious question but is there left any software still using OpenGL? :-) (mesa demos do not count)

The first things that come to mind would be any hardware accelerated 3D graphics not targeting a Microsoft-only platform. Any software or games that are compiled against D3D and run through Wine are implicitly using OpenGL. All iphone and android apps are using OpenGL. Scientific visualization applications are most likely using OpenGL along with any other industry that goes back to the early 90's or before. I don't see a whole lot wrong with OpenGL for my needs, and Vulkan doesn't seem to add a whole lot that I can't do already though it is apparently necessary for pushing the envelope wrt next generation game engines. -metric

You completely left out the difficult parts of the Oculus SDK like corrections for lens distortion and chromatic aberration. Their SDK also does a ton of work when your app can't meet the 75 fps vsync target of the hmd and starts doing its "time warp" frame interpolation based on current head orientation. There's a hell of a lot more they are planning before the final release next year with things like layers for distant objects which shouldn't need to be rendered twice and their custom spatial input controllers.

There's OSVR.. though it appears that they are doing the lens correction via shaders and I don't think they have a driver for the Oculus head tracking yet. I build against the Oculus SDK 0.4.4 on Linux because that's the _only_ thing available to me right now. If only I had the luxury of choice.

NVIDIA's GeForce GTX 980 Ti Costs $350 Less Than TITAN X, Performs Similarly 156

Deathspawner writes: In advance of the rumored pending launch of AMD's next-generation Radeon graphics cards, NVIDIA has decided to pull no punches and release a seriously tempting GTX 980 Ti at $649. It's tempting both because the extra $150 it costs over the GTX 980 more than makes up for it in performance gained, and despite it coming really close to the performance of TITAN X, it costs $350 less. AMD's job might just have become a bit harder. Vigile adds The GTX 980 Ti has 6GB of memory (versus 12GB for the GTX Titan X) but PC Perspective's review shows no negative side effects of the drop. This implementation of the GM200 GPU uses 2,816 CUDA cores rather than the 3,072 cores of the Titan X, but thanks to higher average Boost clocks, performance between the two cards is identical. And at Hot Hardware, another equally positive, benchmark-laden review.

Patriot Act Spy Powers To Expire As Rand Paul Blocks USA Freedom Act Vote 500

Saturday, we mentioned that three major spying powers that the U.S. government has exercised under the Patriot Act might be nixed, as the sections of the Act granting authority to use them expires. The Daily Dot reports that Senator (and presidential contender) Rand Paul today used Senate rules to block a bill which would have extended those powers, which means that as of midnight Sunday on the U.S. east coast, sections 206, 207 and 215 of the Patriot Act will have expired. Says the Daily Dot's article, linked by reader blottsie: The reform bill, which the House passed before leaving town for a week-long recess, would end the government's bulk collection of Americans' phone records under the Patriot Act's controversial Section 215 but leaves the other two provisions intact. ... Sunday's procedural meltdown was the second narrow defeat for the USA Freedom Act. In a late-night session on Friday, May 22, the bill fell three votes short of an initial procedural step after [Senate Majority Leader] McConnell lobbied hard against it. The Senate's failure to meet its deadline was a blow to President Obama, who on Friday had warned lawmakers that the country would be vulnerable if the USA Freedom Act did not pass.

Tron 3 Is Cancelled 205

Dave Knott writes: Tron 3 won't be coming to a theater near you. Disney had been developing a sequel to Tron:Legacy since the movie, made for $170 million, grossed $400 million worldwide. But now they have chosen not to move forward with a third installment in the sci-fi series, sources say. "Disney has had strong success with its live-action properties recently, including Maleficent and this year's Cinderella, which earned $527.4 million worldwide. But it recently had a stumble with the $180 million live-action film Tomorrowland, which underperformed at the box office this past weekend with a $33 million U.S. debut."

Even if they support Linux, you still need people producing content for it that also supports Linux. I have a DK1, and while I did manage to get it going on my gentoo install, there was (and honestly still is) very little to actually play with. I ended up just installing Windows on a second drive.

Most bitcoin public keys are sitting behind two levels of hashes: SHA256 and Ripemd-160. So both would need to be broken to even get the PUBLIC key. The elliptic curve cryptography would also need to be simultaneously proven flawed in order to spend the coin. The blocks in the blockchain, however, just use SHA256 to chain themselves together.. so there might be some advantage to the miners if this was flawed though it might only enable double-spend attacks which would be detectable.

Comment Re:Chinese IP Knockoffs Forgo Branding,Now Bypassi (Score 1) 104


The original Oculus Rift prototypes used a sensor that was readily available on the market, but ultimately we decided to develop our own sensor hardware to achieve an optimal experience. With the new Oculus VR sensor, we support sampling rates up to 1000hz, which minimizes the time between the player’s head movement and the game engine receiving the sensor data to roughly 2 milliseconds. The increased sampling rates also reduce orientation error by providing a denser dataset to integrate over, making the player’s real-world movements more in-sync with the game.
