No, I don't mean the lame simulated HDR in newer games. I mean the real thing. IF this tech becomes big it'll a bigger jump in quality than standard def -> high def is.
The Composite extension currently available in Xorg facilitates an alternative approach, based on XRender which still uses the video card's 2D engine, and that's quicker to implement, but not as robust or flexible.
Repeat after me. There is no formal relationship between XRender and Composite. The Composite extension simply provides a method for an external program to handle how the desktop is rendered. It hands that program a bitmap for each window, and it is up to the program to do something with them. xcompmgr and KDE's composite manager, which is based on xcompmgr, use XRender to blit those bitmaps in the proper order. Luminocity, gnome's next gen window manager, contains a composite manager that uses OpenGL to render the desktop. The point is that composite manager can do whatever it wants to the bitmaps it recieves. It can invert the colors, make it translucent, flip it upside down, or tile a picture of elmo all over every window. That is the power of Composite.
And XRender doesn't benefit from hardware acceleration -- they're working on that now, under the name "Exa"
EXA is the replacement for XAA. XAA and EXA are 2D acceleration architectures. Much like OpenGL is to 3d. They provide the raw methods for hardware accelerate bit blitting, line drawing, 2d polygons, etc. Some cards accelerate more things than others. A video driver can provide 2d acceleration using XAA or EXA and not accelerate the XRender extension. The default configuration for the propietary nvidia drivers does this. However it uses neither EXA or XAA, but a propietary acceleration architecture. Not that it matters much as it is transparant to applications. XRender can, and is accelerated under many drivers. EXA and XAA do not depend on it, though, and it does not depend on them.
but the nice thing about OpenGL is that we already have it accelerated.
We already have 2D acceleration as well. The nice thing about OpenGL is it is usually faster and more feature rich. XGL aims, as far as I am able to tell, to replace all the functionality your typical driver comes with using OpenGL: EXA, XRender, Xv, RandR, etc.
Basically, what this boils down to is that XGL will draw the content of the windows: the text, the buttons, the images, etc. Then, if there is a composite manager, it will send the content of those windows to it, and it will do with them as it sees fit. Once the window contents are sent to composite what happens next is beyond the scope of XGL.
The fact that you even have to ask is pretty damn scary. You seriously see nothing wrong with this? If you wanted to read it, and they visited you, you'd just thank them for doing their job?
Well I'll tell you why it's a big deal then. It's a big deal because it's NONE OF THEIR DAMN BUSINESS. That's why. I'll read whatever I want, whenever I want. I do not need or desire big brothers permission, and if I so wanted I'll do it while hitting the bong and having another man sexually please me. Government needs to stay out of my damn personal life. Now if I start killing people then by all means I'd expect them to come knocking at my door, but not before.
Is this a joke? You see our eyes ALREADY DO THIS. We don't need to simulate it! Why waste time making the dark areas of a game greyscale and blurry when our eyes will already do that for us if the scene is dark?
I read about this recently myself. The biggest downside I see to this is that the array of leds is a MUCH lower resolution than the LCD itself. They use software algorithms that take advantage of the bloom effect to compensate, but that has its limits. I imagine this display would be very poor for use as a computer monitor, especially in the console.
Pan, Konqueror, JuK, Kmail, K3B, tinyfugue, Gaim, Kaffeine, KOffice, Konversation, KDevelop, jack, Kate, kpdf, ethereal, nmap, akregator, tvtime, cron, cups, samba, gkrellm, gimp, and several other apps that are either only run or only run decently on linux, not to mention all the functionality available to me that I do not have in windows.
I switched because I love openness. I don't just love being ABLE to dip into the source of any app I use to learn or change what it does, I love doing exactly that on a day to day basis. I love being able to easily know exactly what my system is doing at any time.
So many links at that tesla coil site, but not a single "wtf is a tesla coil" link. I hate websites like this. Do such website creators not even considering the f'ing possibility that somebody might now know wth their site is about?
First of all VMWare is not technically an emulator. Because of the way it works it can attain very high speeds. Second, VMWare 5 introduced experimental direct3d support into their guest windows video driver that uses OpenGL on the host machine. It is experimental and lacks features, but it does work. You mat not be able to play the latest game that requires a geforce 7800 and a 3Ghz processor just to run decently in 800x600, but many gamers have an extensive library of games that would be possible to play if this direct3d support matures.

In the ideal Linux world, everyone has discard MS Windows, and they are strictly using open source software...
I disagree with this, and I really have a hard time understanding why articles like this think the focus should be on attracting users. Whatever happened to the grand old idea of scratching an itch? It's MY itch damnit. If other people like the software so be it, but an author shouldn't change his vision of what he wants his app to be because some teeny bopper windows kiddie demands he does.
I am of the belief that windows is the way it is because of its users. Masses of willfully ignorant people demanding all the wrong things from a company that must cater to them. Part of the beauty of OSS is we can ignore these idiots, tell them to keep using windows, and to leave us alone. Linux is an OS made by geeks for geeks.... lets keep it that way. Thanks.
I'd be interested to hear more. From what I understand most games don't tax the acceleration capabilities of creative dsps. I've seen reviews where 4 out of 5 games benchmark the same, but a 5th which uses EAX extensively suddenly needs 20% of the CPU to emulate it on the non creative card. I, unfortunately, do not remember the games or where the review was located. Does the C-Media chip even have a programmable dsp? If it does can you show me where to find any details on its capabilities? I've done basic programming on the emu10k1 chip in my sound blaster live. You can do some neat things if you take the time to learn how to program the chip, and I'd love to find a non creative card w/ a programmable dsp in the same price range and with better sound.
I just call them all Malware. That seems pretty accurate to me. I don't care if it only shows ads if it installed itself as a damn driver or hooked the kernel it "Does bad things to your system/configuration."
More to the point, TV ads don't use up my paid-for bandwidth, and are kept rigidly separate from the programmes: You don't get banner ads plastered across the top of the screen in climactic moments of the TV show, but you frequently encounter them on web pages.
Two words: Product Placement
Unfortunately this is not only becoming much more commonplace, but also much more obtrusive and obvious. For a recent example just watch I, Robot. Half the damn movie is an ad for Converse. Even worse.. Harold and Kumar go to White Castle. What the hell is that? Remember the movie advertised a while ago about a girl living in Wal-Mart? There is no clear line between ad and program anymore.
I agree that is a nice card, but it lacks the same feature every non creative card lacks; hardware acceleration. I think even the dolby digital live is only hardware assisted. However Creative has been the MS of sound cards for so long I'll still buy the blue gears card. I am waiting for them to introduce a card based on C-Media's next chip. It will have DTS encoding as well as Dolby Digital, but while the Dolby Digital is 384kbps, DTS is 1.5Mbps. That bit rate is high enough for me to not worry that it is recompressing the audio when I play mp3s.
I understand your situation. Ubuntu is incredibly overrated. Although while I say this I haven't tried any distro, but I have to hope some are better. Ubuntu does NOT like non standard PC setups, and by standard I mean only IDE disks and optical drives, 1 video card, a rather generic and well supported audio card, etc. If it runs into anything even remotely out of the ordinariy it screws up all over the damn place. With me it was a minor issue of having onboard video and a pci video card and not having the ability to disable th eonboard video in my bios. I did, however, have the ability to specify which card should be the primary card in the bios. Despite this ubuntu tried to start X on the onboard video which I was not using and did not have a monitor plugged into. Once I plugged the monitor into the onboard I tried to edit the config manually after it installed only to find out I did not have access to the root account. I had to search google and find some obscure entry on some obscure forum somewhere to find what ubuntu sets the root password to! Overall I must say I am HIGHLY disappointed by ubuntu. It was recommened to me by many people as a great newbie distro to introduce some people to, and in the end I ended up tossing windows xp back on out of frustration. I had an easier time getting Gentoo working on my home box. Pathetic.
then the worst you'll have to do is open the disc in Explorer and double click on something yourself
Speaking of which, even with autorun off if you double click on your cd drive in My Computer with an autorun enabled cd in the drive it'll "run" the cd instead of "explore" it. If the cd installs a driver w/o so much as a prompt you could just as easily get screwed by this lame behavior as you could by having autorun off. Do you know how to turn this "feature" off?
Trust me I know, but if these vendors gave a shit they've had years to make their apps work with non priviledged accounts. One example is Monkey's Audio. I don't know windows at all nor do I care to as I don't use it, but I tried doing this for my dad, but Monkey's Audio complained about some file with an ocx extension not being registered. Winamp won't play music, and takes a loooooong time to start up. Nero requires some tool that it is kind enough to tell you exists, but it won't help you find it.
There are many more examples of apps that just screw up in this configuration. Perhaps for some of us just not using the app because it's obviously broken junk is an ok option, but it's not hard to understand why nobody uses limited user accounts when it's so much trouble to get one working correctly. Software vendors don't care, and Microsoft apparantly only expects such use out of a corporate environment where you have a dedicated help desk. With windows obfuscated registry system and non openness about how to configure shit it not easy to figure out how to manually fix these programs. I searched for over an hour about what to do about a non registered OCX and found nothing. Why do they insist on making this shit so hard?
I use to use tvtome.com just to find the upcoming schedule for new episodes, or to find the season and episode number of an episode I've seen. It was one place to go that could do that for every show. Unless you are looking for discussion, rumors, spoilers, backgrounds, etc. for the show tvtome was more convenient and did the job.
I have never, ever seen a student running in a non-administrator account on their Windows PC, even though XP supports this feature.
Have you ever tried this? Precious few applications actually do this correctly. Most won't install start menu entries for All Users. Others are worse and install themselves in ways that make them not work at all in a limited user account. I think it'd be easier for the average user to install and learn Linux than try to get a limited user account in Windows XP working well.
It sounds to me like you are assuming everybody that switches is switching to hurt microsoft or to take some sort of moral high ground. Unfortunately, these are bad reasons, and anyone switching for those reasons probably doesn't understand the real reasons to switch, which will make switching a bit of a pain. I am assuming that since the possibility of switching for any other reason hasn't quite entered your mind, you are unable to think of any other reasons. Pity, really, but please try to keep in mind others may have better reasons.
Either you are incredibly naive, or you are trolling. I'd almost prefer you to be trolling, but just in case you are that naive I will tell you why the price is that high. You are gleefully neglecting the one thing this thing was designed for.. audio! Very high quality audio components are NOT cheap. Your new dell laptop and your xbox probably don't even come close in audio quality. Any high quality stereo reciever will cost you that much, and they cost that much for good reason.
But those cable/DSL lines are private property, paid for and owned by private companies. Am I willing to destroy the concept of property rights just so there can be "competing" cable companies? No way.
In many, many, many cases those lines may be privately owned, but they are paid for with government grants. To me that makes them public lines.
I've heard this from many people. I've had many friends whos parents forced them to spend X amount of hours outside for every Y amount of hours on the computer. What, exactly, is the big deal about being outside? Will being outside make you a better person? It's not like you have to be outside to stay in shape. I stay in shape by spending my time indoors... in the gym. So why is it so damned important that you spend time outdoors?

This is a review of the only HDR capable monitor in production.

This discusses two methods for creating a HDR capable display and why you would want to. The display in the earlier link uses one of these methods.
Just a few minor corrections :).
