8K is the width, in pixels. Digital film work always talks about picture width - because the picture height is variable, depending on what aspect ratio is being used.
I'm not sure of the exact format that was used on that picture, but roughly speaking, we're talking 8192 wide x 4096 tall x 3 components (RGB) x 16 bits per component - or 192 MB per frame. That's 4.5 terabytes per second.
As far as "theoretical resolution" being 18K - only if you want to see individual film grains. No commonly available scanner goes above 8K so it doesn't much matter what the theoretical number is.
What about the car enthusiasts? To me - and to many other geeks, judging by what's in the typical engineering corporate parking lot - driving is fun. I doubt that the Robocar will have 300 horsepower feeding the rear wheels. The article even points out that the suspension on such a car can intentionally be made extra-mushy. I, for one, would refuse to work on such a project.
Some people want the ability to power slide a car around a freeway on-ramp at 90 MPH - and pay handily for a car that will do so. The drivers of such cars are, overall, far better drivers and cause far fewer accidents than your average parent in a minivan talking on a cell phone. But - such entertaining activities will be banned by our new robotic overlords.
theoretically, couldn't an encoder scan the data stream for keyframes
Well, no. The input is uncompressed video - there are no keyframes. One of the jobs that an encoder has to do is to generate keyframes - i.e. to decide where to insert one. This decision has little to do with the input video.
(It is generally efficient to put a keyframe where the input video changes dramatically - for instance, a cut from one scene to another - but that can't be your only algorithm).
MPEG video is based on macroblocks - 16 x 16 square blocks of pixels - and it is possible to split the processing of these blocks (or more commonly horizontal bands of these blocks) between different processors. However, this requires one parent process to handle the splitting of the input data and the assembling of the final output data - so the parallelism must be built into the algorithm.
So why do they even need to ask their workers? NASA owns some very large buildings.... just replace all of the urinals with waterless ones, and collect the output. Each sample is not uniquely identifiable so there would be no privacy concerns. Many of the buildings are run 24/7 so weekends aren't an issue.
The list only needs to be one item long: Make windows secure.
The first thing any corporate user of Windows does on a new machine is to install anti-virus software. Make Windows secure enough that anti-virus software isn't needed. If Vista was a secure operating system, most people would forgive it's other flaws.
And the reason people were going to the BBC for online content was.... NBC's coverage sucks.
NBC insists on covering the Olympics "live", in prime time. Problem is - the Olympics are being held in a different time zone. So NBC tapes the events, blocks any "live" coverage that it can, and then presents the taped event in EST prime time as if was live. (That's why so many of the events on TV have *surprise* American winners - they just discard the tapes from events where the Americans lose badly).
Hopefully, if NBC is streaming content, they'll stream really live content from all sports. If not... then broadcasters that do a decent job in other countries will see a large uptick in their traffic.
The battery life of a flash-based iPod nano is basically identical to that of a HD-based iPod Classic. However - the battery in a Classic is much larger.
Obviously the use model for both devices is the same.
Pull up a reasonably complex web page (e.g. NYTimes). Click on a link. Now hit the "Back" button. What takes so *ing long to repaint the previous screen that was displayed less than five seconds ago and so is (hopefully!) still in the browser's cache?? I can frag alien life forms at 72 Hz, but a simple browser page repaint takes a visibly long time?
And - do not under any circumstances pop up a new friggin' window unless I ask for it.
Computer jobs are like auto industry jobs. And who doesn't want to work in the auto industry?
Software developers are like automobile engineers: exciting work, developing new products that customers will want.
IT workers are like auto mechanics. Nothing to do until something goes wrong. If some engineer did something wrong, you'll get a steady stream of work patching up their mistake.
Yeah, sure, there are a few auto mechanics with incredibly great jobs (like working for a Formula 1 team). But the vast majority of IT jobs are as exciting as changing oil at the corner gas station.
Windows is, by default, configured to automatically connect to new networks. Which means, it is configured to silently break the law, without your knowledge. The 53% of people who admit to stealing WiFi is probably really higher - many people don't know where thier bits are coming from.
The power went off in my house the other day - and nobody noticed. The four or five laptops in use all silently switched over to a neighbour's network. I can't see that being considered a crime.
The government has more secure systems for people's laptops, like Bastile Linux, and should be using them instead of a consumer grade OS that was never intended to store anything more important than Solitair.
Ah. Been using that Bastille Linux spell checker again, have we?
Sure, criminal behaviour has changed. Instead of using regular cell phones, professional bad guys now use nice untraceable prepaid cell phones (and discard them regularly). So, the data retention has indeed brought on a change - but the change makes the data retention useless.
What the data retention does do, is to trip up the only-vaguely-criminal acts of the amateur. For instance, it is now much easier to track down the affairs of an unfaithful spouse, and to win a nice fat divorce settlement. Somehow I doubt that was the original aim of the data retention.
You can purchase a Vonage/etc. adapter in the USA, and then plug it in anywhere in the world. This works in a lot of places that VOIP is officially "not available" - exactly where depends on the settings of that country's firewall.
So, you're supposed to be sneaking around and not raising suspicion while hacking on a brightly colored plastic computer that looks like a child's toy??
A generic laptop - or even better, a smartphone with wifi - allows you do do the same level of hacking, but look like your average person and not attract attention.
Why is Cisco gear assumed to be "trustworthy"? Since this is all closed source software, maybe Cisco has been secretly spying on us all for years - and this has only come to light because of FUD spread about "chinese" routers.
So.... whatever happened to the iPod? You listened to music, and it worked in every room in your house!! Plus, if I walked into a room where someone else was - I could still listen to my music, while they listened to theirs. Plus - extra special bonus - it actually worked outside the house.
This sure looks like a solution in search of a problem to me.....
So Wal-Mart makes $4.69 on each CD. That's their gross profit. Sure, they have expenses like light, heat, employees... but they have that for everything. They bought a CD for $11.30 and make $4.69 on it - that's a 41.5% markup, which is not bad at all.
Plus, why is Wal-Mart selling CDs for MORE than MSRP? Take the Killers CD "Sam's Town"...
The Amazon.com price makes the article's numbers look questionable as well - if the CD costs Wal-Mart $11.30, how can Amazon.com sell it for $9.97? I'm sure that Wal-Mart has just as much buying power as Amazon, if not more.

It's time to start ditching backward compatibility. Every refresh of the 802.11 spec does not have to have backward compatibility.
You mean in the same way that 802.11b was backward compatible with 802.11a?

I see a major problem here: real life doesn't have a respawn.
The tactics you use to play a game like Counter-Strike (a cooperative military FPS) would be very different if you only got one life every 24 hours.

Do you suppose that George Bush has ever sent an email?
(I mean, by himself - not typed by someone else, or sent on his behalf).
But, where are they going to hide a bluetooth spoofer during a strip search?
Oh, wait, it's a prison... never mind, sorry I asked.

CMTV yesterday announced that they would not be shipping the MMDTVB03 at all -- it would be replaced by the MMDTVB02
What sort of company replaces a product version 3 with a "newer, better" product version 2??

I call bullshit on the numbers.
$0.80 Retail profit
$3.89 Retail overhead
So Wal-Mart makes $4.69 on each CD. That's their gross profit. Sure, they have expenses like light, heat, employees... but they have that for everything. They bought a CD for $11.30 and make $4.69 on it - that's a 41.5% markup, which is not bad at all.

MSRP (according to Amazon) = $13.98
Amazon.com price = $ 9.97
Wal-Mart price = $14.88
The Amazon.com price makes the article's numbers look questionable as well - if the CD costs Wal-Mart $11.30, how can Amazon.com sell it for $9.97? I'm sure that Wal-Mart has just as much buying power as Amazon, if not more.
