And I want to see terrorists flying Mach 5 airliners into buildings. Specially since even the fastest air-force jets or missiles wont be able to catchup with it.
Quoting from the excellent article posted by the parent:
A serious problem that is often overlooked when demonstrating a ray traced game like Quake 3 RT is that while ray tracing scales well for static scenes, it does not for moving scenes. The most important operation in ray tracing is to determine the closest triangle from the origin of any particular ray. This is generally done by building a partitioning tree which allows you to quickly disregard most of the triangles in the scene without actually doing the expensive intersection test. The problem is that computing these trees is expensive, and any change to the location of triangles inside the tree means recomputing the entire partition tree.
The author of that article (Dean Calver) repeatedly gives examples (like the one above) to how doing ray-tracing in real-time for motion scenes scales much worse than rasterization.
I think that this post is just another one in a series of FUD tactics by Intel to set the stage for Larrabee.
Besides nothing prevents current one chip GPGPU systems (like CUDA from NVIDIA and CTM from ATI) from being better than that really expensive cluster.
Exactly.. and the ipod has a fixed interface. So you dont have to look at the click wheel to operate it. The fixed shape and position of a physical button is both an advantage and a disadvantage. I quote a slightly modified form of a dialogue from the matrix: Buttons, they are the quintessential smart-phone delusion, simultaneously the source of their greatest strength, and greatest weakness.
The team I used to work for 3 years ago wanted a web gui layer framework similar to this back then.. and i remember Echo 1.x was one of the first ones we prototyped. Then there also was millstone http://www.millstone.org/ And i think echo was also featured on slashdot http://developers.slashdot.org/article.pl?sid=03/0 9/09/2337216 Echo 2.x seems to have now added support for ajax.. a demo is available here: http://demo.nextapp.com/Demo/app..and it runs smoother than the ajax controls found on flickr atleast. In the end it seemed that the world wasnt ready for this... and higher management didnt like the risk associated with trying something completely new.
Try reading this(i used to have a hp workstations @ work a few years ago) or other similar guides on the internet. A few important points according to me: 1. make sure that your chair and table height are correct/comfortable for you, you should not have to bend forward (refer to ergo guide for what correctness means) 2. invest in a good chair with sufficient lumbar support & hand rest, should cost around $150 (adjustible arm-rests wud be great too) 3. make sure that the keyboard and mouse are placed properly, if required get one of those ultra adjustible keyboards especially if you are going to be typing all day. 4. take frequent breaks (and that doesnt imply reading/.) 5. try to get some exercise for you back wrists and neck atleast a few times a week, dont ignore any pain in joints (could be CTS)
Before, when copying 40 GB of movies/tv/pr0n from your friend's removable HDD, your computer would tank, practically deadlocked.
I believe disk transfers are mostly done using DMA, the processor isnt really executing a loop for copying data (check ur cpu usage during a copy)... the deadlocking i think has prolly more to do with the IO interface being choked.
You are right about the amount of available parallelism though, architects/designers simply dont know of any good way to use all the real estate on the chip to run single threaded code faster (curse the signal propagation delay)... and its much easier in term of chip verification, design costs etc. to add a dupe on the chip. No matter how many core's we have on a chip... single threaded performance is always going to be important unless we shift to a more parallel programming model.
One major problem with in-order architectures is that its hard for them to do useful work during cache misses... they simply cant fetch out of order and have to just stall in almost all cases, whereas outta order can manage to use atleast part of the miss penalty. But this does come at the cost of complexity and power.
If only everyone was taught to think and program in parallel since birth...
hmmm... I understand straight, gay, lesbian etc. but taking a bath with an intelligent computer... is there a term for such stuff ? What if HAL prefers his own kind ?
"We did finally make the Minidisc machine everbody knew Sony was capable of," said Miyazaki, "but at a considerable cost." Some members of Sony's vaunted Shinagawa engineering labs have apparently felt the burden has been too high however; since January over two dozen engineers and scientists have left to join Google Japan where, it is rumored, a wireless portable audio device with a wow-factor exceeding the iPod is under development."
Now why isnt this on the frontpage instead of MD's sad death.:-(
So many bad things have happened to Sony just because of the constant struggle with the Entertainment division.. crapping up so much innovation. Google could prolly be THE company to set things right in portable music.
I hope they fixed the nasty default very-low quality setting of MS Paint when saving images as JPEG's... or atleast made it configurable. In the hands of the uninformed thats enough to destroy a beautiful picture.
yea.. i know what u mean !! If i was there i would have introduced a much purified sample to mebbe start a resonance cascade reaction and then mebbe opened a few portals to u know where.. where's that crowbar now !
This should be one of the fewer (or maybe the only) instance of a live video feed site beeing slashdotted by appointment. Sad that Zonk wanted to give them a fair notice... well.. Bring lets 'em down !! hee haaa haaaw !!
Has anyone read the rececnt edition of TIME on google... I remember one of eric or sergey or larry commenting that they wanted to make philanthropy a business !! So look at this as an investment.
Hey u r forgetting the very important BLINK state...;-) so that wud make it 2 bits... now wat cud i use the 4th state for ? or mebbe the BLINK was being emulated in software.
Damn... this card is no good for the water heater i had built with my 6800 SLI config...:-( Nvidia cant deny us our warm water !! well there always is ATI.
interesting.. i wonder whether SLI would allow it to play some of the newer DOOM3 level games ?
hey i wanna play quake3 on my ipod !! while watching a video on my TV... but wait a minute, does the ipod video have a TV-out ? Well, i have played Doom on a Sony Ericsson P800 while on a high speed train in europe, and its kinda *nice*... feels like playing it on a wide screen.

How about registering and trademarking TheSimpleDawg.com/simpledawg.com instead ?

Do two people count as a party ? (Me and my computer ?)

So finally the tile processor architecture makes it to the industry. People in the comp arch group at MIT envisioned and prototyped something pretty similar to this years ago as the RAW processor.b er=13382&arnumber=612254

..and mebbe add in a little A.J.A.X. to asynchronously slashdot all the stories ?

Those results are kinda interesting... a comparison between alienware and dell notebooks on the alien site!! Are'nt they gonna take them off ?
Whoa!! finally we get to dissect and run experiments on the aliens now ? Better barcode them first.
Maybe the game is just plain entertainment without all the blood and gore being assumed by everyone here.
