Since most academic research groups are not overly flush with cash, the authors put these results in terms that someone holding the purse strings would understand. It terms of computing power per cost, the PS3 delivers 50,000 LUPS/dollar, the super high performance IBM QS20/QS21 runs at 3500 LUPS/dollar, while a quadcore desktop machine is capable of putting out 17,000 LUPS/dollar.
However, there seems to be the issue with the memory though:
The researchers point out that LB simulations take a large amount of RAM and, when moving to a three-dimensional simulation, the amount of RAM will become very important. Since the PS3 has only 256 MB of RAM, even moderately sized 3D grids could end up being written and read into swap memory, which would be a significant performance bottleneck.
Or you do what I do: use xubuntu. I cant imagine running full ubuntu on less than 1gig.
Have you actually tried Ubuntu out with 256Mb? I ask because what you're saying directly contradicts this article which says Ubuntu is actually easier on the memory than XUbuntu: http://www.linux-mag.com/cache/7520/1.html
And the subject of the article is of great relevance of course, LUbuntu, which supposedly beats both XUbuntu and Ubuntu's pants off.
Ok, I know this isn't technically on topic and I'm sorry about that... but I'm having this problem with Firefox on a few sites and since I haven't found anyone else that suffers from this problem I haven't been able to isolate it properly.
I just tried submitting a URL to tr.im and after doing so my browser bogged down and slowed to a crawl. My CPU usage jumps to 50% (so 100% of one of the two cores I have) and my whole system becomes ill-responsive. Meanwhile the "answer" section of tr.im is "fading in". So the problem seems to have something to do with opacity in HTML rendering.
Slashdot crowd: please help me... is anyone else experiencing this problem?
I'm running Firefox 3.5.2 on Kubuntu 8.04 with an NVIDIA graphics card and my XServer version is 7.3.
I know this is late and all but wuala might suite someones needs:

It's a distributed file system.
Pros:
- Owned by LaCie
- Uses distributed P2P technology to store data fragments (your data is encrypted and distributed).
- Ability to "trade storage space" (donate your hdd space and bandwidth for more "distributed storage").
- Multiplatform
Cons:
- Java application on your desktop:-(

There are already tests that check for some genetic markers that increase the possibility of prostate cancer. An example is decodeme.com, if you take their test you get a genetic profile about yourself with information about a few (34) known diseases and traits. One of them is prostate cancer.
It may of course very well be that they have developed an even better indicator of the risk you have of getting prostate cancer... but the article made it sound like this was a completely new thing.
If your software team is having problems with the significance of white spaces in Python, my bet would be that, no offense, the team was to blame.
The trick is to coordinate the "white space rules" between members of the team. If it can't pull that one off, I wouldn't trust them to write code for a production system anyways.
Please mod parent up, it's true, this is bullshit!
Monolithic libraries in C++ restrict your freedom? How in the world do you get to that conclusion? FYI, almost nobody uses MFC, and if it bogs you down, well duhhh... don't use it!
C++ is almost exactly the way it used to be, the language hasn't changed at all. You can still do everything by hand like you used to if that's what you want. The "monolithic" libraries you speak of tend to help the rest of us get things done and I for one, welcome a more diverse selection of these.
Well, or you could just not use Amazon S3 for your big ass project.
I like the fact that I can use S3 and only pay for what I use, even if it means that it wouldn't be cost efficient for me to do that if my usage goes through the roof.
Don't think of S3 as your "one and only" storage solution. Think of it as a great starter kit and possibly an excellent addition to your existing infrastructure.
For example, I know that a rather big video sharing site uses S3. I'm not sure what the details are exactly in their case but perhaps storing the very popular videos locally but offloading the rest to S3 for storage and infrequent access works for them?
Bottom line is, this is the service that they offer. If it doesn't fit your needs either adjust your needs to fit their offering or, even simpler, don't use their offering.
I guess this really depends on how interested your kid actually is in learning the internals of computers. It might be a good idea to start with a "high level" tool, and I'm not talking about using Python or some such thing, but using Alice and/or LEGO Mindstorm. I've played with Mindstorms myself in a robotics course and I can vouch that you can do a lot of fun and interesting things with it. There's even a C-like programming language and compiler that you can switch to when the "block interface" becomes boring and your kid gets interested in learning more "orthodox" programming.
Once he has a solid knowledge of basic programming and if he's still interested in learning more of the basics of how computers work and if you are willing to dedicate quite a lot of time and effort to destroying the social life of your kid once and for all and turning him into a full blown geek I'd recommend that you take a look at a course that has been called "From NAND to Tetris" in which students are given a NAND logic gate and must construct their own (simulated) computer out of that by gradually building on top of that NAND gate. Eventually they end up implementing a simple game, such as tetris or snake in a computer that they build from the ground up.
Above all else I think you need to be sensitive to your kids needs and longings. Who knows, maybe he will not be interested in all about learning the internals of computers but more interested in the usability and design of interfaces (I know, your worst nightmare I'm sure). My point is, don't push him into a direction that isn't to his liking.
Well, it's a little complicated. I think the largest amount you can get is around 25.000 ISK (it varies between banks) and since we have a central "hub" for all bank transactions that all banks are connected to, this is a per day limit. In other words, you can't exceed the 25.000 ISK withdrawals limit in total per day (per card of course), no matter how many different ATMs you visit (even from different banks).
Yes, I did realize that the headphone jack had to do with accessibility for vision impaired people.
But just out of curiosity:
1) How easy is it for a blind person to figure out that a) the ATM actually has the headphone jack and b) where the plug is located?
2) Do vision impared people usually carry headphones with them to use with such devices?
Additionally, the headphone jack might be a good idea if it actually worked! I tried plugging a pair in myself and got only the sound of silence. Maybe someone thought it would be funny to play a joke on them?

oooh... cool... so how "rapid" does the impact have to be???
I'll give you a hint. The answer can be found somewhere in the first 8 words of my post: "The behavior of this stuff sounds a bit like..."
The behavior of this stuff sounds a bit like the Smart Mass Thinking Putty I have from ThinkGeek.com.

Well done... you just managed to piss of three religions in one comment!
I decided to verify your research.
OH MY GOD THEY'RE MULTIPL-*CONNECTION LOST*
I decided to verify as well and concur with your findings. 298,000 images of gnomes.
I also found that turning off the "safe search" feature resulted in a total of 305,000 images being found.
Can someone please tell me how I can get only those 7,000 additional images?!
"FREE (not as in beer) TIBET!"
... weavers. Probably not the fanciest title to put in a job ad but I think it catches the work they do rather nicely.
There is never enough porn to watch!
There, fixed that for ya.

Python is absolutely unusable on real world projects (any project where you aren't the sole developer) due to that indentation crap.
Would you mind repeating that? I don't think the guys developing the following projects heard you:
I could go on... but you get the point.

hosted vs. stand-alone
Yeah, I'm sure a hosted Operating System would totally rock!

Exactly, as they said: The Internet is for Porn
They'd never enforce something like that - they'd lose 40% of their subscribers overnight.
Hmmm... OK so how exactly do those other 60% get around the ban and download their porn? Please share!
