Roadrunner is open for unclassified research for 6 months IIRC, but will be reserved for classified research for the rest of the time.
I'd really, really, love to learn about the programming practices one follows for a computer like that.

McCain Backs Nuclear Power
·
· Score: 2, Insightful
Any idiot can see the need for nuclear power and cheap oil now. It's funny how we only see the need for something which takes 10 years to build when we need it today.
A real leader would have seen it 10 years ago.
I'm not impressed. Building new power plants is a proposition that a 6th grader could write. These politicians act like their geniuses when their train of thought appears to be "If people scream about problem X, then we fix problem X.". It should be "X will become a problem in 5 years. Better start fixing it now."
Amen. I'm amazed that some Paul observers don't understand basic economics.
We didn't get off the gold standard/Bretton Woods because someone wanted to scratch an itch or was bored. It COLLAPSED, and would have taken the world economy with it.
Maybe Paul has a way around it that his supporters haven't been able to explain to me. However, whenever they talk about his policies and I respond "we tried that once, it collapsed", they kind of walk away dumbfounded...
Wave of the Future? Yes*. Revolution in computing? Not quite.
The GPGPU scheme is, after all, a re-invention of the vector processing of old. Vector processors died out, however, because there were too few users to support. Now that there's a commercially viable reason to make these processors (PS3 and video games), they are interesting again.
The researchers took a specialized piece of hardware, rewrote their code for it, and found it was faster than their original code on generic hardware. The problems here are that you have to rewrite your code (High Energy Physics codebases are about a GB, compiled... other sciences are similar) and you have to have a problem which will run well on this scheme. Have a discrete problem? Too bad. Have a gigantic, tightly coupled problem which requires lots of inter-GPU communication? Too bad.
Have a tomography problem which requires only 1GB of RAM? Here you go...
The standard supercomputer isn't going away for a long, long time. Now, as before, a one-size-fits-all approach is silly. You'll start to see sites complement their clusters and large-SMP machines with GPU power as scientists start to understand and take advantage of them. Just remember, there are 10-20 years of legacy code which will need to be ported... it's going to be a slow process.
The Internet2 is a clever name for a semi-public, semi-private ISP which provides a large amount of bandwidth to universities. The way they can afford to do this is by having a private network only between paying universities and not having to pay for network data to travel across commercial networks.
Oh yeah, and it also performs some research. Note how none of it even comes up in the article
That is correct. I work in an organization which deals exclusively in certificates (everyone also encrypts with S/MIME). The CA does not keep the private key.
If the NSA compromises your CA, the best they can do is create another certificate which pretends to be yours. If the destination already had your certificate, then the public key they have won't match your private key.
For me, it's simple - it gives me an idea of what RHEL might look like in a couple of years.
I have access to a couple tens of thousands of servers which run various RHEL derivatives. I have access to none that are Debian derivatives.
One of the best things my boss has taught me to do out of college is to listen to people. Sometimes a person gets whiney or edgy (and if I got a call at 3am, I'd be bitchy too); listen to them, filter out the abusive parts, and find the parts which you need to listen to.
Finally, if there's anything which needs to be addressed, let them throw their tantrum, and bring it up again later on.
Don't know about this case, but it works 90% of the time for me.
It's going to be a race, really, to see what happens first - the Tevatron squeaking out enough events to confirm detection, or the LHC operating smoothly enough to get all the calibration and background processes established, then finding the Higgs.
It's going to be a close race. On one hand, the LHC will ramp up to have a huge advantage over the Tevatron. On the other hand, the Tevatron folks are at the top of their game.
Estonia.
A lot of the congressional meetings are held online, bills are not printed out, the president signs bills with the click of a mouse. Citizens even vote on the internet.
The problem is that you have too many options in your table. I'll simplify the case and assume car is behind door one.
Strategy 1, always switch:
Choose one, then switch: LOSE
Choose two, then switch: WIN
Choose three, then switch: WIN
Strategy 2, always stay:
Choose one, then stay: WIN
Choose two, then stay: LOSE
Choose three, then stay: LOSE
Your first choice is "which door?" (three options) and the second choice is "stay or change?" (two options). So, you have a total of six paths to winning or losing. Your mistake in the above table is assuming that "you choose one, monty chooses 2, you switch" and "you choose one, monty chooses 3, you switch" are distinct possibilities.
It's not an easy problem, read the wikipedia article a couple more times...
In response to this, Microsoft made fundamental changes to the way Windows Vista was linked together; shifting more towards modular designs rather than the monolithic processes used in previous versions of Windows. This increased amount of componentization, while satisfying the DoJ and EU, also led to performance issues due to the increased number of libraries which comprise the operating system. On traditional hard drives, the more separate files which the operating system has to load, the more seeking across the hard drive is required, and therefore overall performance takes a hit.
Hmm... so, the reason Windows Vista is slow is because it has too many files? I mean, I understand the overhead of loading DLLs is non-zero, but really?
He goes on to explain that the problem with Unix is that when you upgrade, you lose compatibility with old applications because the libraries change. I'm not Unix wizard, but I'm damned sure that you can always just keep copies of your old libraries and get about anything to run. That's why you can still run old Mosaic Netscape versions, right?
Finally, he claims that they will replace all existing frameworks with a new monolithic framework. I'm sure.NET is going to get a version bump for Win7, but replacing it? Hell no.
Isn't this what the CIA did to the USSR? They purposely sold the Soviets Counterfeit CPUs and other technology so their economy would be based on faulty technology.
In fact, it culminated in the mid 80's when a brand new pipeline was turned on with turbines taken from America via a Canadian intermediary. The turbines purposely malfunctioned and the resulting blast was about 1/4 the size of Hiroshima. Taking out such an important oil pipeline made a non-trivial dent in the Soviet economy.
My understanding was that they sat down and figured out the minimum volume of liquid you need to make a bomb large enough to take down a plane, and decided you couldn't hit that volume in X many 3 mL bottles.
Then again, that understanding was based upon a cable news report, so it could just be complete BS.
Yeah, you're right, they aren't even close. If I got this in a CS class, I would fail someone.
Why would you bother ripping off the code? Any decent Flash jockey could re-write this game in an hour or two. However, any low-paid, entry-level programmer in another country could just take the code and decide no one will notice.
A tornado can do what, couple million dollars of damage, tops?
A hurricane can do many billions of dollars of damage.
In fact, my homeowner's policy in Nebraska is incredibly cheap compared to what a similar one would be in Florida (even taking into account that my current house would cost 2x as much in Florida...)
Except you forget to take into account the cost of living differences with respect to geography.
In Nebraska, $75k is middle-middle class and $100k is upper-middle class. $250k is "rich people's land". $75k will allow you to buy 2 new/fairly new cars, a 3-4 bedroom house (a good one in a good neighborhood is about $150k) in a good area of town, and support a kid or two. If you raise the taxes on folks making $150k or more, you would probably hit = 1% of your earners.
In California, the cost of living is dramatically higher. I claim the Federal income tax brackets ought to depend on geographic location.
Most of Europe, from my understanding, has very strict privacy policies regarding personal data. You must have data retention policies detailing when the information will automatically go away, always allow customers to opt out, and always allow customers to remove their data.
Thank god we have freewheeling capitalism where companies can sell my personal data with no consequence.
I'm sure someone can point out something wrong with the European system, but it sure is a whole hell of a lot better than the US one.
I hate to say it, but the Reg might be right. Assuming the linked CV is the real thing, he only claims to have experience with Excel macros and a smattering of VB.
The real part of his hack is probably social engineering and stumbling upon oversights in the trading system. How many IT folks, even the dumb ones, can say "I could take this whole system down if I wanted!" - this guy actually did.
Goes to show that there's a difference between checking off boxes for auditors and actual security. Auditors can make sure the proper safeguards are in place; auditors can't tell if everyone in the department uses the same password.
Stock investors lose their shirts and tech companies close down? It's a hiccup, but no problem. (Most) people still have jobs, but the economy corrects itself after a few months of recession..Coms lost everything, but the "backbone" of the economy is fine. Just the flashy part caused everyone to lose money.
This time, I worry. The people who caused this aren't the flashy folks who just sprung up months ago, this time it's the banks that are dragging things down. The core economy itself needs a correction.

Thus resulting in the fact that European countries are faring high oil prices better than the US because they are better leveraged?
WE SURE SHOWED THEM! USA!
Have you ever seen a midwest state? You can effectively put a power plant which is 100 miles from any town.
Then, all you need to do is figure out how to *transport* all that energy to somewhere useful.
Ha, that's waaay too low. Here's the international traffic for one project I work on, CMS:
http://t2.unl.edu/phedex/xml/quantity_cumulative?link=dest&span=86400&starttime=time.time()-30*86400
Total is 3.7PB over the last month. I doubt that one science experiment accounts for 40% of global IP traffic in Cisco's estimates.
The funny thing about that contest is they state you have a very low probability of winning if your program is over 200 lines of C.
So - 1 underhanded line out of 200 LOC takes skill to do. Imagine what you could do with 1 million LOC.
Amen. I'm amazed that some Paul observers don't understand basic economics.

Indeed. I remember during the 2004 presidential election hearing a girl ask "Mom, I forget, which one are we again? R or D?"
That is correct. I work in an organization which deals exclusively in certificates (everyone also encrypts with S/MIME). The CA does not keep the private key.
If the NSA compromises your CA, the best they can do is create another certificate which pretends to be yours. If the destination already had your certificate, then the public key they have won't match your private key.

Hm.. let's select a portion of the code you posted:
From China:
bonus_mc.bonusPtsTXT.text = score;
bonus_mc.bonusCtTXT.text = "X" + _loc5.length;
bonus_mc._alpha = 100;
bonus_mc._x = ice_mc._x;
bonus_mc._y = ice_mc._y;
From the other one:
bonus_mc.bonusCtTXT.text = "BONUS X " + cloudCount;
bonus_mc.bonusPtsTXT.text = cloudCount * 100;
score = score + cloudCount * (cloudCount * 10);
bonus_mc._x = xpos;

bonus_mc._y = ypos;
