"In 2010 the volume of digital information created and duplicated in a year will reach 1.2 zettabytes, according to new data from IDC and EMC. The annual Digital Universe report is an effort to visualize the enormous amount of data being generated by our increasingly digital lives. The report's big numbers -- a zettabyte is roughly a million petabytes -- pose interesting questions about how the IT community will store and manage this firehose of data.

Even in simple cases of move from here to here in more then 1 burn can not be numerically solved with current technology (damn computers too slow)..
I'm not sure why the parent has a 5 Informative tag... The writer probably meant that the case couldn't be solved *analytically*.
An analytic, or closed form solution is where you derive a model that explains exactly what will happen in any situation. As far as orbital dynamics is concerned, this is only possible with a two body problem (and perhaps a few special cases of three body problems). When you can't solve a problem analytically, you turn to numeric methods. No matter how fast your computer is, it is not going to figure out an analytic solution for you for this kind of problem. If an exact analytic solution exists for an N body problem, it most certainly won't be discovered by some brute force method.
NASA has made numerical calculations for this flight (basically by iterating the forces involved at each point along the proposed path), and they know the result with a high degree of accuracy.
To save space, the library used a VARCHAR(16) for the full name, so every time George returned something, there was an buffer overflow, and the database had to be fixed by hand.
Seems like twice, they just forgot.
If Adobe wants to, they can make their "compiler" a language engine that rewrites a flash/flex app in objective C. Apple doesn't want java apps and flash apps because they lose the unique look and feel of the device. Java apps look terrible on windows, mac and linux, because they live in their own interface world.
Obviously an app that can be written once for all platforms is not good for Apple's business, but I think Jobs is more interested in making sure all the iApps, have the same distinct look and feel that makes iphones and ipads so intuitive.
Certain settings can be changed on an iPhone just based on links/downloads clicked on from within Safari (on the device). That is how iphone os 3.0.x users could enable tethering without jailbreaking their phones. It was just a settings file that could be downloaded. I believe it was unsigned, but now, apparently it would be easy to make it look like an apple signed file.
I always thought the Need Another Seven Astronauts joke was pretty dumb. Airplanes don't need to sleep, so you always have multiple crews per aircraft. Commercial airlines usually have 4 to 7 complete crews per airplane. If you lose any aircraft, you don't need more crew, because you instantly have a surplus.
How about motorcycle like steering connected to a Beechcraft Bonanza style "throw over" column, so the wheel can be quickly transferred from one driver to the other with out loosing the advantageous feel of a standard steering device.
It actually can be better than with Wifi. If you pace around like I do while talking on the phone, you'll find all kinds of little weak spots around your house/yard that will disrupt a call. I've made some phone calls in the past with skype on a jailbroken iPhone, and it worked fine, but there was really no point since I never use all my regular minutes.
People who need to call international will like this a lot though.
I don't want to bash it just because it was designed by a Microsoft scientist, but...
A circle is really hard to read and jumping away from the center and then counterclockwise to get to the next "row" is wacky. If you can't read the numbers very well, you won't be able to tell what order the elements are in.
Won't it look nice on a Zune HD (chemistry edition) though?
Well, switch to SAS drives, and replace each 1.5T sata with 3 450G SAS with 1,500,000, and you will also have drives fail at the same rate. (3x longer mtbf but 3x more disks). Seems like you are really criticizing lack of tiered storage, rather than consumer grade hardware here.
Additionally, if you RTFA, you would see that they were using RAID6 + a hot spare and have split up their arrays so they are not too big and do not end up with ridiculous rebuild times. A RAID6 + HS solution will not lose data with a double drive failure, and can handle three drives out so long as the first parity segment has been rebuilt by the time the third drive fails.
Clearly this solution would not work for most enterprise needs. It is just disk based backup, and with the hardware they are using, it is just barely "online", but certainly far more "online" than tape would be.
On top of all that, the company explains what they are doing, so their customers know exactly what they are getting into. You do not pay $5/month for unlimited backup and expect to get a high-end tiered backup system with high availability.
If studies have shown the human eye can perceive as few as 5 photons (some say even fewer is perceivable), what exactly to they mean by 1000 times fainter? Just spread out in time, I suppose.
...That's a unit of energy (in case you didn't have time to RTFA). If they can't make a simple table without screwing up their units, can they really make a car?

In a diesel, the fuel is injected into the cylinder.
FTFA: "Once the fuel is injected into the piston, the heat and pressure are enough to cause the fuel to combust without a spark"
No, what we have here is a true revolution. This company is only one step away from screwing spark plugs directly into the fuel tank.
but to an android, it is nearly an eternity.

I'm so tired of these ridiculously thin 2D laptops that always slip silently down behind the desk and disappear.

And then you'll know if your boss reads Slashdot.
I don't like how in that simulation, there is a 0% chance of a survivor killing a zombie. How about some hope!
I can't find any reputable references online for for this though.

I agree with the "Hey! Let's just make Shit up" poster.
How exactly is this newsworthy?
Come on, Slashdot. I like apple as much as the next guy, but this is just pointless.
That's really nice. I was so tired of reading the /palm version on my iphone. Thanks for the link.
The question is: Will fusion always be 50 years away? Hopefully not, but so far, that has been the trend despite all the research.
(just like in 1950, Fusion Power was going to become a reality in the year 2000 and in 1970, Fusion Power was going to be real in 2020)
I can't wait!
I had a QM professor named Schroeder in grad school. Maybe the parent did too. That joke came up more than once.
