Efforts to implement NVIDIA's Video Decode and Presentation API for Unix (VDPAU) on the open source Radeon Gallium3D drivers (for AMD/ATI chipsets) are reportedly just beginning to work. Being Gallium3D-based means this new VDPAU state tracker is using GPU shaders and not the dedicated Unified Video Decoding (UVD) engine found on modern Radeon HD graphics processors, but using shaders is still a big performance win for HD video playback compared to pegging the CPU constantly. Also, MPEG-2 is the only codec known to work at this time. Once the basic state tracker functionality works, support for other video codecs, such as VP8 and H264, should be relatively easy to add.

They where "slow" just as much because of old school fixed function GPUs as they where because every company had to reinvent the wheel by coming up with their own proprietary method of doing the same thing that did nothing but case massive compatibility problems with accelerated apps and games back in the bad old days.
These days with unified shaders they can implement allot more features allot faster, hence the *.1 releases backporting new features to older GPUs that can still handle the new extensions.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.

The day has finally come: Google has started shipping Google Glass to the lucky few early adopters. Now that it's shipping, Google has also unveiled a lot more about the API and the specifications of the device itself. While the company had already given out substantial details at earlier occasions, there are still a few surprises here.

Almost exactly three years ago, I wrote about why OSNews was no longer OSNews: the alternative operating system scene had died, and OSNews, too, had to go with the times and move towards reporting on a new wave of operating systems - mobile, and all the repercussions that the explosion of smartphones and tablets have caused. Still, I was wondering something today: why aren't we seeing alternative operating systems on mobile?

You can say what you will about Windows Phone and Windows 8's Metro interface (I refuse to drop that name) - it's inefficient, unpopular, cumbersome, beautiful, ugly, organised, clean, limiting - but there's one thing we can all agree on: it's unique and distinctive. CNet has published a profile of Microsoft's Albert Shum, the man behind Metro, and he highlights what I think is at the very core of Microsoft's problems in mobile right now.More Features »

Remember how slow the OpenGL consortium used to be?
That was for agreeing about software standard. Now care to wager how long it would take to get people to agree about hardware standards? We'd end with too little or too much, after taking way too long.
If you want to be able to support new tech, then we don't have a set-in-stone standard, and what good is it, then?
A minimalist interface, say modesetting and basic 2D acceleration + compositing would go a far way, and could probably done in UEFI. I don't believe in anything more than that.
I do wish hardware vendors would be more open and release specifications, but OTOH there's the whole point about R&D costs and patented tech that might even have been licensed from other companies.
