Is there security on that? No of course there's no security on that. I mean, just because we have been able to make proper encryption and authentication for the last 30 years doesn't mean we'd want to put that into a pacemaker. What ridiculous thing will they propose next: Passwords for computers? Launch codes for nuclear missiles? PIN codes for your ATM?
You could use it to describe that the phases/periods are not synchronous, ie that they are different. But this isn't the normal way you'd use it. An asynchronous connection would be more like one where the capacity varies with time.
The chip in the Xbox 2 is very similar to what's in a power mac G5. The chip that's going in to the PS3 is pretty much unlike anything avalible today.
That said, it's possible that there will be a 1/4 speed xbox2 emulator for the G5 powermacs at some point, seeing as how the G5s were shipped to xbox2 developers as development machines. I'm not sure I'd agree with you that the Xenon (in X360) is similar to the CPU in a Power Mac G5. From the Ars articles on the CPUs the (in the Xenon case gurestimated) execution unit layouts are:
PowerPC 970 functional units [1]
* Two floating-point units
* Two integer units
* Two load-store units
* One branch unit
* One vector unit
The PPE's execution units (note that there are 3 of these cores on the Xenon chip): [2]
* 1 integer unit
* 1 floating-point unit
* 1 branch unit
* 1 load-store unit
* 2 VMX-128 units
Basically, less power to the normal execution (FP and int) and more to the vector processors. Apparently the instruction set in the vector units on the Xenon (and Cell for that matter) are subsets of Altivec they do have some specific additions to optimize 3D processing. So while they are similar, they are not all that similar. The Xenon is clearly optimized for a very specific purpose.
It may be possible to emulate the simple games like Geometry War on a G5, but I doubt it'll ever happen. If for no other reason than that I imagine encryption on the X360 will kill off a lot of those possibilities. It'll be far more efficient to just reimpliment those few games on the target platform than to make an emulator. (Not that this has ever stopped hackers before.)
Also consider that the other parts of a X360 differ a lot from what you find in a typical computer. And for historical reasons you can consider that while the Xbox is extremely similar to a Intel PC there are still no emulators for it (there are some proof on concept emulators, but they don't work well).
and you quickly lose definition in the lows. Take a picture of a test card with film and with a digital and you'll see what I mean. I'll give you the highs, but from what I've seen of comparisons between digital and film, digital handles shadows better than film. That's with good dSLRs though, the small sensors in compacts is another thing.
I can't really make the comparison myself though as I don't have access to that kind of equipment. The cost of professionally scanning film is often astronomical (for very small astronomical distances).
So get a charger which can use 12V from the car. (Not sure if one exist you can buy, but you could make one.) Heck, there are even solar powered chargers on the way now.
Invention Disclosure: This patentable and novel process is first published December 21st, 2005. Feel free to use this technique today for your own photography, but camera designers should contact me before implementing it in firmware. Thanks!
Perhaps the guy should credit the people who had the idea before him. And not only that has a much more profund understanding of what is actually going on. I recommend reading the Expose (to the) Right and the Understanding Histograms articles. Short story is that if you only underexpose the image then you will lose detail in the image.
Furthermore, the entire underexpose and push in Photoshop idea was not created a month ago.
On second though, this is the guy that compared the 20D to the D70 and concluded that the extra 2Mpx in the 20D was useless but that the faster flash-sync of the 70D is absolutely vital (1/250 vs 1/500). Google him and you'll find quite a few humorous threads discussion his ego.
That said, this advice is basically sound. Just as long as you know that there are trade-offs. When comparing digital and analog the import part is to understand that analog handles overexposure better, and digital handles underexposure better.
The biggest problems with taking all your photos in this way are that they're large (very large, relative to JPEG), and you either must use proprietary camera software or plugins for software like Photoshop For the first part of this statement, I find that when I take pictures with my 20D the difference in size isn't that big. It's like 2MB for JPEG and 6MB for RAW. (I had a couple of shots taken in JPEG(Large, Fine)+RAW). If you want to do more advanced stuff like noise surpression then RAW is the way to go.
For your second statement there is a OSS RAW converter out: DCRAW. AFAIK it produces better quality images than most software you get with cameras. (Though it may not be as good as the professional tools.)
The other thing about digital vs. film is that when I buy a film camera, I can expect to use it happily for years.
Is that because when your 3Mpx model is replaced with a 6Mpx model in the makers line-up it will suddenly stop taking good photos?
I've made more progress with a digital camera (dSLR) in a year than any time previously with analog models (SLR). The reason is that I can take a lot of pictures and evaluate them quickly. Eg just this week I played around with taking a lot of macro shots of flowers. So I set it up, took 50+ images and loaded them over to the computer. I can now spend a couple of minutes reviewing these and checking for errors and mistakes and then retake the photos directly.
You can't do that with analog.
Regarding tonal range, you're pretty much right. (Though IIRC the "effective range" on digital and analog are about equal. What really differs is that while digital is brutal with the cut-offs analog makes it possible to push the film a little extra in the highs and lows, to rescue a photo.) But with digital I can instead take 10 pictures with different exposure and then composite them with HDR techniques. That is really hard to do well with analog. (Unless you take multiple analog pictures and go to digital and then do the assembly.)
It's correct though that dSLR is for people with a lot of money. But today you can get a good dSLR for the price of high-ish quality lens. If you're a serious photographer you'll spend more on the lenses than the camera anyways.
But then you can't do colour, you'll have to get a high quality scanner (only that will offset the price of the digital camera) and you'll have to spend a lot of time doing the developing.
And in the end the results will not be as good.
Many pro photographers gone digital that I've read about has "saved time" as one of the biggest benefits with digital over analog.
BTW it's worth mentioning that many of the chemicals used for development are nasty so there's an environmental issue as well. (As a personal health issue, the same chemicals are bad for you.)
No, the vector elements in a Cell are not capable of doing the work of a GPU. Nor are they intended to do it.
A typical GPU is the same size (or larger) than a CPU, and it's optimized for pumping out pixels. It will take more than 7 DSPs to do the same work.
I'm sure that the PS3 and X360 will be about equal in power. But they are different enough that it may help make the exclusive games differ in interesting ways.

The problem is that the two cars I was driving at the time both either didn't have ABS, or the ABS didn't function because I was on a very slippery surface.
As someone else already posted, those are ideal conditions for ABS to work. In my experience in breaking a car with ABS doesn't leave any doubt that the ABS is working. You will feel the break pedal pulsate quickly and hear a sharp grinding/rattling noice from the hydraulics system. If the ABS is active you will notice. (And that is the way it's supposed to work, don't ease off on the break.)
Furthermore I think that in many conditions ABS will break your car faster. Particularly on wet surfaces as the moving wheels will continue to pump water away from under the wheels and ensure that the car doesn't begin to "surf". (I'm not sure what the english term for this is wrt cars.)
Though I think that in ideal conditions (dry tarmack or similar) ABS will still be slower than good 'ol locking the breaks.
And seriously, from your description above it seems like you over-estimate your capacity to drive. I have *never* had an ABS system activate when I didn't need it.
The reason I want ABS breaks to be standard (and perhaps other automagic system as mentioned in the articles) is to protect me from other people that can't handle their cars. These systems are not there to make you a sloppy driver, they are there to save people (hopefully other than the sloppy driver) when the shit hits the fan.
Same in Sweden and Norway. Not sure about Finland, but it would surprise me if they didn't have similar rules as they have the same (or worse) driving conditions.
Personally I'd love to see more of that. First off, it's a lot of fun. And second, skidding around a bit like that is a great way of getting respect for your car. After the first time you are in a car which is out of control and there's nothing you can do about it you do get some more respect for driving carefully.
When I entered "sleep to ram" into google the entire first page was full of relevant hits. Look into the Wikipedia article on ACPI for more info.
AFAIK the reason this isn't always turned on in Linux has historically been due to compatability issues. (As in, the kernel coders have had to reverse engineer things and it has sometimes caused unstable behaviour.) Depending on your distro and hardware configuration I'm sure there are plenty of times this works out of the box on Linux too.
Other than that, you're not supposed to turn off a Linux machine.;-) You'd know that if you were actually a Linux user and not just trolling.
Well thanks Anand for posting comparison shots between BR and DVD taken with a mobile phone camera. I'm sure that'll do justice to the resolutions. (Hint, next time try using a camera resolution that can at least capture NTSC detail.)
My personal experience (from Tokyo Electronics Show last autumn) is that HD does give an edge. It's most likely very dependent on the content though. (Eg there are some really impressive comparisons between LOTR in DVD and 1080p formats.)
I was going to just mod this down but let me argue the point instead.
You are severely misinformed. It's true that the X360 and PS3 have monstrous GPUs and can shovel polygons to the screen faster than before. But that's just one part of the system. The CPU cores are quite capable of processing data and their power has not been sacrificed in favour of the GPU. Rather the CPUs have been boosted to even more ridiculous levels compared to previous generations.
It's also turned out that the DPSs in the PS3 are not as limited as was once thought. They do (as the Xenon in the X360) have some branch prediction and will be able to handle themselves. Also note that while next gen cores may not have quite the branching logic as a standard CPU it's expected that developers spend more time to optimise for a console than a normal PC.
Since there are no data on the Revolution yet any speculation on its power is just borderline trolling IMHO. However, considering that Nintendo seem to aim for the slightly cheaper market again it's not reasonable to assume that it will be more powerful than the X360 and PS3. It may well be easier to get performance out of though, but that's hardly the same thing.
The problem with developing for next gen consoles will not be that they lack power. The problem is that the power will be harder to get the most out of.
That said, the clear winner in the next gen consoles is (as always) the gamer that gets all of them.
If you want to do the same in Linux look up "sleep to RAM" and "sleep to disk".
It's not a complete boot though, you only reload the last state the computer was in. So if your PC is getting cranky (leaky programs and such) then this quick boot method probably won't fix it for you.
BTW, one of the reasons WindowsXP is so quick to boot is that it does things in parallel. You can do this in Linux as well, look up "make boot" for that.
Not really, you can create a lot longer words in Swedish if you want to. Although that may very well be the longest words that's officially avaialable.
There why an article about sociopaths in a Swedish magazine for engineers. Basically they pointed out that people with those disorders are more common among managers than in most other situations. The reason being that their disorder typically aid them in getting promoted. The article was basically about what to do if you had such a boss. Their tip was to not pick fight with them and either let them take credit for your work (which they often do) or find anew place to work.
It should be pointed out that it is an illness though. Much like aspergers or ADD I so it's not like they can help it. (Though they could make an effort.)
Also an important aspect of MMOs seem to be cooperation. So it really makes more sense to have a dungeon present a specific challenge. If the adventurers don't match up then they'll have to overcome that or find additional players to help them out.
Kind of the point of the game really. (Well, theoretically anyways.)
As someone who has a 10-22mm (about 16-35 35mm equiv) for a 20D I can say that while 23mm certainly is wide, it ain't no ultrawide. I wonder how they solve the flash with a wide lens though. The build in flash on a 20D can't handle that wide. And you really need a separate flash to get good quality.
For those who own a dSLR I recommend getting an ultrawide lens (there are good third party ones too). It is seriously the most fun I've had with a camera! The pictures just tend to give you a lot more "oomph".
Slashdot Mirror
Consider that a GPU today is as big (or bigger) than a CPU and then consider if it's really all that expensive.
Naturally high-end stuff carry a bit of a premium price too. You can get good cards for below $200.
Is there security on that?
No of course there's no security on that.

Asynchronous means at different times.
