Would these "proper optics" cost thousands of dollars and only be available to military customers perhaps? And have you actually experienced it yourself?
Let's talk about stuff that is actually available..
There wont be a generation 2. No-one is buying the generation 1 glasses.. so there's no money to develop the generation 2 glasses. Until someone who is sufficiently passionate about this stuff develops it on their own dime and then has enough business smarts to actually get the product to market, we're never going to have the "virtual light" displays. Maybe some funding channel will open up one day and we'll get government development of this technology, but NASA and the military seem to still be blown away by regular head tracking head mounted displays and CAVE systems, so it won't be for decades if ever.
Umm.. no. I actually own a head mounted display with head tracking.. the simple fact is, scanning across a display that is half an inch in front of your eyes is worthless. In fact, the only way to get immersion from it is to block all the light coming from outside the displays and wait until your eyes into "tunnel vision".
Sigh. It's a standard part of critical thinking. Assume the values are correct.. assume there's somebody, somewhere, who has those values. They care about the environment and they have an SUV and a dog, which should they get rid of? If the logical, scientific, quantitative answer is their beloved pet, then maybe there's something wrong with the question. Maybe the rest of us should rethink laying blame at the feet of the SUV owners of the world.. maybe we should stop being fucking facists about it and admit that different people have different values and we don't have the right to tell them what they can and cannot buy on the free market.
that's the entire point.. it's right there in the report.. your SUV uses half as much as your pet, your plasma uses under a tenth. Even if you did both at the same time it would be better. I think the point is: stop being an eco-nazi.
This is the DNI we've been waiting for... The surgeon pops open your skull, injects some strategic locations with some gene altering viruses and installs some flashing lights. Now you can do two-way communication with a computer. What you experience depends on which cells were modified, and what program you're running. With sufficient funding for targeted research, we could see this technology in new kinds of: cochlear implants for the deaf, vision implants for the blind, artificial limb control and feeling for amputees.. and the continued improvement of those technologies will eventually lead to full sensation virtual reality immersion for anyone who can afford it. And we haven't even gotten into the gritty details of what we can learn about the brain using this technology.. reverse engineering is so much easier when you can poke as well as peek.
Sorry, you're not the kind of apologist I'm talking about. You don't care about open source either.. fine, you two enjoy each other. My objection is to the asshats who think NVIDIA "can't" open source their drivers and so people who do care about open source should give them a free pass. They can, they choose not to.
Q: Are there any plans in place to provide new features within the xf86-video-nv driver or to better engage with the Nouveau developers for some open-source support?
With the nv driver, we've always tried to provide something minimal that just works out of the box and requires the least maintenance. For that reason, feature set in the nv driver has stayed pretty slim.
The guys working on nouveau have done a really incredible job so far. However, our policy remains the same: we won't try to hinder their efforts, but we have no plans to help them.
Scumbags.
Q: AMD was able to open source and/or document a lot by separating out the parts they couldn't legally disclose. Similar problems have been cited as preventing NVIDIA from open sourcing their driver (licensed 3rd parts code, etc) or documentation. Could nVidia use the same strategy?
A similar strategy might be technically possible for NVIDIA, but for better or worse I think it is quite unlikely. There are several reasons for this:
- For competitive reasons on other platforms, I don't think we would ever open source any of our cross-platform driver source code (which is 90%+ of the Linux driver... see my earlier description of code sharing). The Linux-specific pieces of the driver code base don't really stand on their own, and generally need to change in sync with the cross-platform code, so I don't believe it would be practical to just open source the Linux-specific pieces.
- We have developed substantial IP in our graphics driver that we do not want to expose.
- Unfortunately the vast majority of our documentation is created solely for internal distribution. While at some point it may be possible to release some of this information in pubic form it would be quite a monumental effort to go through the vast amounts of internal documents and repurpose them for external consumption.
Yes, and there's a whole community that would like to help you do that. That second answer is the real point here. They don't want to open source it because they don't believe in open source. It's that simple. Hopefully this will kill the last of the NVIDIA apologists.
You remember that bit in The Road To Perdition where Tom Hanks demands justice for the mob boss's son killing his wife? The mob boss says "huh? we're all murderers here." You lie down with dogs, you get fleas.
Yes, but as the chart shows, the energy density has a hell of a lot of margin.
Hell, growing ethanol is more effective than making batteries.
The real difference is that full electric cars are charge at home.. people currently don't care about this but I think when it eventually becomes common place they'll wonder how they ever got used to having to go to a fuel station to "recharge" their car.
Huh? Neither is an ultracapacitor.. I think I was making a perfectly far comparison.. you can store energy for mobile application in a battery or in an ultracapacitor (worse) or in hydrogen (better).
Unless you're in the US. Every time I'm there I see someone on the side of the road with a car fire. What's with your shoddy cars that they just burst into flames?
The ultracapacitors are made of activated carbon and have an energy density of six watt-hours per kilogram. (For comparison, a high-performance lithium-ion battery can achieve 200 watt-hours per kilogram.) Clifford Clare, chief executive of Foton America, says another 60 buses will be delivered early next year with ultracapacitors that supply 10 watt-hours per kilogram.
Or, to put this in more sensible terms. 0.021MJ/kg (0.036MJ/kg next year) for an ultracap vs 0.72MJ/kg for a lithium-ion battery. Aka, the tiny bottom left square in this chart. Compare this to, say, gasoline at 47MJ/kg or even hydrogen at 142MJ/kg and you start to get some idea of why people are excited about "the hydrogen economy".
In less than 3 months, I would spend just as much on a maid as a Roomba vacuum costs
If, after 3 months, you haven't realized that your Roomba is a toy that can't do a tenth of the job of what it is required to do then you're doing better than most of us.
I *hate* to get into a humans vs robots argument, but seriously, just hire a good maid.. you'll never think robots are close to the same capabilities of humans again.
I wish every "home robot" designer would do this, maybe we'd start getting some robots that are actually capable.
Slashdot Mirror
Sure, but you're still going to see a rectangle of display. If this magical lasers on the retina stuff can do better than that I'll be impressed.

Let's talk about stuff that is actually available..
done it: http://quantumg.net/tigeronvmware.php deleted the image shortly after.. yawn.
Maybe if there was some place I could go to get up-to-date torrents of vmware images I might care, for the novelty.

But that's all that is on the market.
Yup.. and it's the best head mounted display you can buy for under $2000. If no-one buys these things, they'll never get any better.
Ya, augmented reality continues to suck, but if no-one bought the Altair we never would have gotten the machine you have on your desktop today.
http://www.vuzix.com/iwear/products_wrap310.html
Available right now for under $250. Also one of the only head mounted augmented reality systems that is commercially available today.

Ya know, really there is. Neurosurgeons are doing it every day. People with epilepsy are being *cured*.
wow, you and I seem to be the only two who read it.
This is how bad Slashdot has gotten.
or intelligent conversation it seems.
If you'd bother to read the article you'd discover that's exactly what they're doing.
I recommend it, it's a good read.

The system is abuse.

Finally, now we can make "the ball" guard from The Prisoner.
