GNAA Announces Project to Port Slashcode to ASP.NET
GNAA Announces Project to Port Slashcode to ASP.NET
Fremont, California - In a surprise announcement, GNAA has announced a truce and alliance with the popular news for trolls website Slashdot.
GNAA member godspeed broke the news at an early-evening press conference, announcing that GNAA would cease trolling the website, and will instead work with the current Slashdot staff on porting the Slashcode to ASP.NET, to be run under IIS.
"We've had our difference with Slashdot in the past," godspeed began, "but with recent slowdowns in performance on the website, they have finally realized that Opensource is indeed dead, and it's time to move on and replace their antiquated codebase with something that will meet the modern day's needs. We're pleased to be given the opportunity to work with the Slashdot staff on making this port. Of course, the new code will not be opensourced, an NDA will be signed in blood by all who see it and if you release it, the penalty... well, you've seen what happened to Nick Berg, Paul Johnson, and the others. Major changes to be implemented include the removal of goatse link evasion, major overhauls to the karma system, and the replacement of pinkpages with LastMeasure,"
At this point godspeed turned the podium over to fellow GNAA member goat-see and stormed out of the room. goat-see offered to take any questions the audiencemembers have. When asked why there were no Slashdot representatives at the conference, he was quick to reply "You can speak to CowboyNeal outside after we're through here, we couldn't get that motherfucker in here without widening the doorframes. Next question?," eliciting a hearty chuckle from the audience. When asked the reason for the sudden change in relations with Slashdot, goat-see paused to think for a moment, before answering "Our historical differences were meant to hilight the flaws in the Slashdot system. As soon as the staff realized what an impacted shitpile their site was and the need to update it, we were the first to volunteer to assist in the migration. We look forward to seeing the hight performace of ASP.NET pages with a MS SQL backend as much as any other nigger out there."
bare, a GNAA member sitting in the audience, stood up and confirmed this announcement with a hearty "LOL." goat-see concluded the conference at that point, saying "If you have any further questions, please direct them to new GNAA member Wil Wheaton, now let's all go outside and poke that fat fuck CowboyNeal with sticks."

Hmm, I've never seen any serious computing grids that are open to outside networks or that run windows.
I think its common wisdom to isolate grids from the internet and other potentially hostile networks.
But a grid's very strength -- its distibuted nature -- makes it vulnerable, indeed, they're finding.
Ewwww, awkward!
Better: But the grid's very strength, its distributed nature, makes it more vulnerable to these types of attacks.
Or: However, they're finding the grid's strength -- its distributed nature -- makes it vulnerable.
This is one of those times dramatizing a sentence makes it worse.
Cue in jokes about studying the slashdot effect on grid computer...
But seriously, what can simulate a DDoS more accurately than a bazillion slashdotters trying to RTFA and get the slashdot fix?
Did anyone else read that as "NIST Studies Virus, DDoS Effect on Girls?"
I suppose DDoS'ing a girl is a pretty good way to give her a virus.
Slashdot is proof that Sturgeon's Law applies to mankind.

Does anyone know anything about the scienceblog.com site? It doesnt seem very reputable considering all the ads and the very obvious SEO technquies (look for the hidden links at the bottom).
In America we are imprisoned by our fear of them.
one of the disadvantages is that the same data will be sent to multiple computers. You can see that they used a grid computing system to create the article:
From the first paragraph:
Grid computing takes advantage of ''down time'' when computers are not using their full processing power to provide quick answers to problems in fields such as genomics, engineering design and financial services. While parallel processing typically involves tying together multiple computers at a single site--all using one piece of software--a computer grid may be much more geographically dispersed, composed of many heterogeneous computers whose availability may change over time.

Crushing dreams at the speed of sarcasm
can a grid contract the gay flu?
i read the title as...

"NIST Studies Virus, DDoS Effect On Girls"
And just noticing the word "girls" on slashdot i was exciting to read the article... until i realized i read it wrong.
The perfect web ad for the slashdot crowd!
is to turn off your bloody computer and GO OUTSIDE. Get off your fat lazy fat asses you fat lazyass geeks and GO OUTSIDE! You know, that room with the big blue ceiling! It's nice out there! Who knows, maybe some of you nerds might like it so much you'll forget about your l337-5|i11z and become productive members of society! Maybe even get a REAL girlfriend!
Then again this is Slashdot, land of the terminal geek. At least none of you useless fucks will ever reproduce.
Gov't studies effect of viruses, DDoS on grid computers

By connecting hundreds or even thousands of computers together to work on a single project, computer scientists are more frequently using a technique called grid computing to do previously intractable computations. Grid computing takes advantage of ''down time'' when computers are not using their full processing power to provide quick answers to problems in fields such as genomics, engineering design and financial services. While parallel processing typically involves tying together multiple computers at a single site--all using one piece of software--a computer grid may be much more geographically dispersed, composed of many heterogeneous computers whose availability may change over time.

While parallel processing typically involves tying together multiple computers at a single site--all using one piece of software--a computer grid may be much more geographically dispersed, composed of many heterogeneous computers whose availability may change over time.
Computer scientists at the National Institute of Standards and Technology (NIST) recently launched a new project to improve understanding of how computer grids react to volatile conditions. A computer grid's strength--the teaming of many computers--also makes it more vulnerable to failures, viruses, sudden changes in workload and cyber attacks such as denial of service. NIST researchers are developing computerized models that will help establish how vulnerable grid networks are to failure. They hope to create ways to detect failure quickly and then fix the problem.
Originally developed as a way to connect supercomputers working on extremely complex problems like climate modeling, grid computing is rapidly finding commercial applications. Already some investment companies are using grid computers to analyze shifts in financial markets in real time. And pharmaceutical companies are beginning to use them to overcome the computational challenges of developing new drugs.
As commercial applications grow, protecting such networks and ensuring their reliability will become more critical. The NIST researchers hope to complete their models by early next year.
NIST Studies Virus, DDoS Effect On Grids
Boy are they in denial. Yeah sure, it was all just an experiment...studying, right....
Now the first step in any virus infection is admitting you have a problem (You havent patched), the second step is allowing others to help. Just these easy instructions and your grid will be sasser free in no time....
Dont worry, despite popular misconception its not just typical poor grannies with fat pipes that fall victim to script kiddies. Some think its the stress that comes with a high responsibility job of a computer scientist at an goverment research body makes one extra suseptible. Unlike grannies computer scientist are likely to try to hide the fact they are infested to avoid imbaresment.
How to recognise a victim:
You may notice their work is slowing down and they may take decades for even the simplest urgent security tasks Then they will start their denial. When questioned about stuff like this the typical computer scientist in denial will respond its the NSA that made him recommend the intentionally broken crypto years after its publicly cracked and that his or her grid isn`t really infected but that he/she is just "researching viral distribution paterns".
How to help:
Forcing someone like this to admit the problem takes time. It is best if you just direct these victims to you local script kiddie victims anonymous gathering. After a few sessions most victims will want to enter the 3 step program on their own... Ofcourse there are the more discreet commercial venues for helping with problems like this but they just want to get you addicted to virus paterns.
Remember it takes courage to admit you have a problem. This has been a script kiddie victims anonymous service announcement
Kind of a waste because it has exactly the same text as scienceblog. same text as the scienecblog.
Friends don't help friends install M$ junk.
I think its common wisdom to isolate grids from the internet and other potentially hostile networks.
So you want to build a third internet? Sounds great, so long as you let me into internet 2, which was built specifically for grid computing on university sites. When you migrate to internet 3, will you promise to keep it windoze free as a demonstration? Sooner or later people might understand how insecure commercial junk degrades a network.

The way I understand it, they're talking about all the cubies in Charles-Schwab and Raython and Citibank, with Folding@Home and Seti clients running as screensavers. Not dedicated clusters; just plain old ordinary workstations.
And I'd imagine the viruii and worms and DNS outtages all take a serious bite out of their collective assets...
Informative.
A GRID is a non-centralized distributed system, sharing storage, processing and connectivity with quality of service guarantees, over open protocolls. Is that about right?
Last summer, I was in Barcelona for a class trip. We visited the European Center for Parallellism of Barcelona (Like there are redundant arrays of Barcelonas. Well, there's the smaller town/city of Badelona right outside Barcelona.)
Anyway...
The CEPBA is a partnership with IBM. I talked to one of the IBM researchers there. They very much believed in the GRID as a distributed system that would hold all your personal data for you, and where you would buy your processsing power and storage from big vendors. Thus users wouldn't have to keep up with the hardware advances themselves.
I suggested that some of the less time-critical processing and storage resources could be provided by the nodes themselves. He did not buy into this idea.
This philosophy reminds me of the old time-sharing systems of yore. If GRIDs are really deployed to a vast number of users, I would predict that users with smaller processing power would team up and sell their (lower quality?) processing to other users, much as the F***** Article says. The only thing that could preclude this would be an enforced requirement that only reputable vendors provide services with QoS guarantees, and digital restrictions stop users from selling their cycles.
Why not have several layers/levels of quality and security? That's much of the point of QuS, isn't it -- telling what's your worst offer and the client deciding beforehand wether to accept your service level?
Oh, look: Now their saying that institutions really WILL be able to pool their resources What is GRID compiting
Looks like I was "getting with the program" better than that IBM guy was. Either he misunderstood or given wrong information (something I've done a few times and been ashamed of), or is a firm believer in that Those darn kids will never provide the computing power! Only me and my VAX!
Irene KHAAAAAAN!
This hypothesis seems to go against logic but maybe it holds some water until things change a little. When you have one very good point of control to access to the system where is the difference then? Also when distributed systems use multiple locations as well as multiple configurations doesn't this create a more survivable system? The laws of nature clearly say that biodiversity is directly linked to an ecosystem's success. An attack or technical problem can not effect every part of a diverse system in the same way. Lately I have been comparing the laws of nature to the laws of technology and I have come to he simple conclusion that since computer systems are governed by the same laws it is inherent that the laws apply equally to there functioning parameters and design. This area of convergence between the laws of nature and computing is to interesting to ignore. Software could be developed by writing an ancestor program and creating random variations that are 'naturally selected' by simulated use and disruption of the population of software being tested, evolving software basically.

I've always just likened a grid to one big computer composed of many parts, which makes the next bit easier to visualise.
As a grid basically has all the connected boxes on the same framework, the possible attacks could either be external or internal to the grid. If external then it's either the fault of the underlying OS or the grid itself and should of course be repaired. Just like a single computer.
However I think it's unlikely that internal infection could occur (which is how most networks get infected) as for one the virus has to be written especially to take advantage of the grid, i.e. no script kiddies, secondly infecting the grid would infect your own box as it is part of the grid. Just like a single computer.
Also because the of the way resource allocation and processes move in grids like globus it'll localise the infection first, so if anything your box would get most of the infection and then only start trickling outwards.
But they're finding a grid's very strength -- its distributed nature -- makes it vulnerable, indeed.
This is more fun than the Soul Train Scramble Board!
