Tshirts given to Terascale VolunteersI volunteered time to help get some G5's ready for this baby, and I think my favorite moment was getting the tshirt all volunteers received:
It is quite the fashion statement

Ordering through iTunes
Though those of you who aren't at VT can't see this image, it's still quite hilarious.
Apparently Tech ordered the G5s through iTunes: http://computing.vt.edu/research_computing/terasca le/images/g5ordering/IMG_0099.JPG -
Cold Fusion"and Neural Networks: Similar FatesWhat is happening to the research in the cold fusion also happened to the research in neural newtorks. Please read the following.
To briefly summarize the tale of woe, Frank Rosenblatt invented the perceptron in 1957. It had one layer of artificial neurons and sparked an entire field of research in artificial learning. In 1969, Marvin Minsky at MIT wrote a book called "Perceptrons: An Introduction to Computational Geometry"; in it, he mathematically proved that the perceptron could not solve certain classes of problems. This book essentially decimated funding for neural-network research for about 15 years.
In 1982, John Hopfield at Caltech revived the field with the invention of the Hopfield Networks. Further, several researchers invented backpropagation as a way to train neural networks with 2 or more layers or artificial neurons and overcame the limitations that Minsky indicated. Now, the field of neural networks has plenty of money to do research.
So, there is a possibility that research into cold fusion will grow hot again.

Re:Java's not exactly pining for the fields just n
#1) Java was NOT originally developed for embedded systems. It wasn't until the past couple of years that Sun has moved it into that direction. (There is a difference between embedded systems and a cross platform VM)
BUzzzzzzzz... sorry, wrong. Java, originally named oak, was intended to be a language to develop for consumer electronics gear, set top boxes, etc. I refer you to this article as evidence. -
FIRST reliable supercomputing facility...
Or so they claim here. It seems they have all their bases covered and don't give a damn about ECC for a reason.
[Srinidhi Varadarajan, an assistant professor of computer science at Virginia Tech, and Jason Lockhart, director of the College of Engineering's High Performance Computing and Technology Innovation, initiated the venture at Virginia Tech. Varadarajan is an expert in reliability, a key issue in successfully exploiting terascale computing.]
They keep on going:
[Component failures are endemic to any large-scale computational resource. While previous generations of supercomputers engineered reliability into systems hardware, today's high performance computing environments are based on inexpensive clusters of commodity components, with no systemic solution for the reliability of total machine.]
And now for the solution for your reliability problem.
[Virginia Tech has the first comprehensive solution to the problem of transparent fault tolerance, which enables large-scale supercomputers to mask hardware, operating system and software failures - a decades old problem. It's a software program called Deja vu, designed by Varadarajan. He also integrated the software with Apple's G5s. This work will enable the terascale computing facility to operate as the first reliable supercomputing facility, according to Varadarajan, a National Science Foundation Faculty Early Career Development Program (CAREER) Award recipient.]
So maybe, just maybe, you and other people could:
1. READ before posting.
2. Then READ a little more.
3. Did I say READ already.
-sigh- Whatever. -
No increase, decrease!
Why don't you zip it and please read the facts from the horse's mouth:
["Virginia Tech will have one of the top ranked supercomputing facilities in the world, supporting significant "big science" research. It is anticipated that Virginia Tech will realize at least a five to one return on this investment in terms of annual research grant and contract activity," says Glenda Scales, assistant dean of computing and distance learning at Virginia Tech.]
Let me say that again: Five to one return of investment projected. At least. If they are saying this outloud, I can assure you Ms. Scales knows what the hell she's talking about.

Re:"Beef up their Website"
It was a random, inane, and completely useless comment. This, coming from someone with a joke for a website. If VT's website needs beefing up, pudge's website is the cow that died 5 years ago and has since been picked clean.
Seems to me the design for Virginia Tech is just fine. They could stand to get rid of their table-based layout, but it's not a horrible site. Pudge is just being an asshole. -
I agree
I just graduated from there and that website, while not ugly, is non-sensically arranged and the search comes up with some of the most ridiculous links. The department does have some nice clusters already set up though as well as a sweet 3d visualization studio!

"Beef up their Website"
Can someone explain the " Maybe VT can use the new computers to beef up their web site" comment? It loads perfectly fast for me. It looks pretty good. It even runs PHP, so it couldn't be a "They shouldn't use ColdFusion" type remark.
Am I missing something, or was that just a completely random comment? -

Re:Do they have a need for it?
Obviously you haven't looked at VT recently. Tuition and fees is only $7,500, out of state. I can only wish that my tuition were that low. Hell, for in-state students, the room and board is the same price as tuition (around $2,000). But of course, you're modded up insightful, because you pulled a random idea out of your ass and presented it as fact.

Talk about a ton of desktops in a server room
For the ones who are questioning this existence, the order is shipping, the racks (a ton of them) are there in the main Computing Center server room. First they required all servers to be moved innto racks. Then they started moving servers around, including removing the Petaplex. The power has been upgraded in the server room (the UPS backup generator actually). This caused a morning of basically all the important servers on campus having to go down for one day in the summer - I hated waking up to go switch off machines for that one. The AC has been upgraded to accomidate the huge amount of heat to be put out. It was't until I heard about the cluster that all the chages in the Machine Room made sense. Now they're recruiting help to do the grunt work of putting all the machines in the racks.
The stated objective was to be on the next 500 list. Dell and HP were considered, but they couldn't fill the order in time (possibly as they have made announcements of other large clusters recently) and Apple promised delivery after someone leaked the story of the cluster meetign with Dell and HP to Apple and Apple jumped at the chance.
Basically, the story is not a rumor from the point of view of the geeks on campus who have been effected by the preperations. I'll probably post the /. link to the campus geek list (If someone hasn't beaten me to it).
I'm disapointed about this being only on the Apple section of /. since a cluster this size is noteworthy of the frontpage. (Rumor - and this is rumor sice I haven't goe to direct sources on this - is that it will not be running OS X, and probably BlackLab or YellowDog or SuSE.) -
It's true.

Making... oh... ONE good thing about the Empo.
Well, maybe 2. The chairs are pretty comfortable.
Kinda curious why the Empo needs them, especially in the budget crunch. But I shouldn't complain (especially since I'm now an alumnus), I'll just watch University Surplus and score a used G4 from there for cheap once they retire them in favor of the G5s. (WOOHOO!) -
Re: NOT reverse engineeringI am not a lawyer, so do not use what I say as legal advic.e My understanding is that verbatim copying of a program will usually involve copying expression of other creative aspects of the software (beyond those covered by fair use, merger, scenes a faire, etc.), which would be copyright infringement.
However, you ask a really good question that has been asked since the beginning of copyrighting software and the CONTU panel. Here is one reference to it:
"By 1974, Congress saw a need for investigation into the effects of technology on copyright issues. The National Commission on New Technological Uses of Copyright Works (CONTU) was created and given the task to study problems that were arising. CONTU presented their findings and recommendations in 1978. Their suggestion was for the enactment of an amendment that would clarify the scope of copyright protection on computer software. This recommendation resulted in the Computer Software Copyright Act of 1980. This amendment added the definition of a computer program and a new section 117 concerning an owner's exclusive rights of computer programs."

Re:ChoiceIf you read the computer requirements for computer science majors you will see that they also require to you be able to run mandrake linux.
In FAQ they respond to the question "Do I have to use Windows XP Professional on my computer?"Certain assignments or software in some classes may require the use of Windows which is available in the Computer Science undergraduate labs. If you do not run Windows on your computer, you will miss an educational opportunity to learn Windows administration, which is a marketable skill. The Department will not check that you are, in fact, using Windows XP Professional. However, if you choose to run Windows 95 or 98, you will almost certainly experience increased difficulty in the programming classes.
The requirement is more of a guideline for people who don't know what to get. And the original poster is probably just a karma whore who doesn't know what he/she is talking about. -

When Windows Update fails...
I can't get windows update to install fixes on my machine either. However, as long as it's downloading things correctly, you can still install things manually from the download location (a hidden folder which is, AFAIK, c:\WUTEMP by default). If it's not downloading them correctly, check out Daisy, which basically just parses lists of updates available, determines which ones you don't have installed, and wget's the installers directly.

Re:life expectancy
Actually, humans are more likely to die from old age than from "other" causes. This is indicated by a "Type 1 Survivorship Curve".
Other species, such as those with predators, don't tend to die as much from old age.
Of course, there are other "natural factors" besides aging that kill us off. -
Blackboard
This is probably having to do with "blackboard" software, i.e. learn.vt.edu.

Re:QWERTY speeds typing. QWERTY 4ever!
However, Dvorak is absolutely dreadful where the alternating left-right hands is concerned, which accounts for an awful lot of QWERTY's speed.
I'm curious what your source for this is. Everything I have read indicates that one of the goals of the Dvorak layout was to increase alternating hand typing. As an example, I dropped the text of your post into the applet here. For Dvorak, ~23% of characters were typed with the same hand. For QWERTY, ~35% of the characters were typed with the same hand. Try it with most English text, and you'll find similar results. Of course, I haven't audited the code for the applet (though I probably should).
If you do trust the applet (man, I should really verify the results to be sure :-)), here are some observations about the Dvorak layout:
1. You stay on the home row more.
2. You alternate hands more.
3. You change fingers more.
4. Your fingers don't travel as far.
Well, whatever the reason, I feel more comfortable typing on a Dvorak layout :-). Everyone else can do whatever they want :-). -

As it was in the beginning is as it is and will beNothing new for Gates and M$ accomplices. See this syncophantic review of Gate's early computer "work".:
It was not long before the young hackers started causing problems. They caused the system to crash several times and broke the computers security system. They even altered the files that recorded the amount of computer time they were using. They were caught and the Computer Center Corporation banned them from the system for several weeks.
Bill Gates, Paul Allen and, two other hackers from Lakeside formed the Lakeside Programmers Group in late 1968.
.. The first opportunity to do this was a direct result of their mischievous activity with the school's computer time. The Computer Center Corporation's business was beginning to suffer due to the systems weak security and the frequency that it crashed. Impressed with Gates and the other Lakeside computer addicts' previous assaults on their computer, the Computer Center Corporation decided to hire the students to find bugs and expose weaknesses in the computer system. In return for the Lakeside Programming Group's help, the Computer Center Corporation would give them unlimited computer time [Wallace, 1992, p. 27]. The boys could not refuse. Gates is quoted as saying "It was when we got free time at C-cubed ..."Was the degraded perfromance was a direct result of Gate's activity? Was this really the model Gates grew up on? It surely matches his company's means of using bugs as a means of extorting money out of their users. Microsoft's time is every bit as over as $1,000/hour charges to run a 16 bit PDP-11. Hopefully, the extortion will end with it.

Interactive Coursework
At Virginia Tech, we have a 802.11b wireless network that includes several buildings and the coverage is growing. Only certain degree programs such as Architecture and Engineering require laptop computers. These programs offer courses that require students to interact and use their computers in the classroom. The number of courses is small at the moment but is expected to grow exponentially in the future.

Re:They just now figured this out?
I thought a big part of the RIAA's argument is that the labels have to underwrite the promotion and some of the costs for the tours...
From what I have read this is not true. Most record contracts state that all/most costs related to marketing and distribution will be recouped from the artists cut of the CD sales, not the record companie's. Of course this means if the record doesn't sell well the record company doesn't get all that money back through the artist's cut... But it also means the artist will get nearly nothing.
I wrote a paper for school on how I morally justify downloading mp3s which outlines the way most record contracts work. -
Fable of the FableThe site mentions Liebowitz's article that contrary to common sense and empirical data the QWERTY layout is better than the Dvorak one. Lieby claims Dvorak (the man) used special texts designed to make his keyboard look superior, but you can try it yourself on virtually any text and verify Dvorak's numbers.
Dvorak users consistently report less effort in typing and that it just "feels" better, but they must be wrong since QWERTY is better. QED. Even though the fastest typer uses dvorak and other dvorak typers cleaned house in competitions, these results are all faked or "suspect". Even though all reason points to markets acheiving local maxima, just like theory says they should, Liebo insists that if one just defines the value of technology based on what the market has chosen then it proves that the market always right.
And oh yeah, therefore Microsoft never had an OS monopoly.

Re:A couple things
Sure, I trust testing. After all, if an OS seems to work right most of the time, it's fine. If my copy of mozilla doesn't crash within an hour, it will never crash. Since the Therac-25 underwent stringent testing, it was perfectly safe, right?
BZZZZZT! Wrong answer. Evidence shows that testing cannot be trusted to reveal all defects. No matter how much you test a system, there is still a very significant risk that it will contain a defect. That's why practically all critical systems use a PROCESS to prevent errors from getting in. That's why the military forces Ada for all systems, why off-the-shelf components aren't used for life-support systems, and why MIL specs are not just based on reliability tests. Since neither Linux nor WinCE underwent any type of certification, code audit, or specialized quality-control processes, they cannot be trusted despite what tests might indicate. -
Re:They both work well
I think letting "I hate Microsoft" or "I hate open source" sway your decision is unprofessional
Many of the reasons that people hate Microsoft are very relevant to what is the best tool for a job. Microsoft has a very long history of screwing over people, including their own customers, they have a long history of insecure products, a long history of bugs, a long history of thwarting interoperability, and many other things which really should be considered. People who hate Microsoft and apply this to their choice of tools to use for a job may have just internalized the knowledge of the risks that generally come with using Microsoft products. It doesn't just matter how well the product works, it also matters whether the company that makes the product is going to knock on your door a year later demanding that you prove that you paid for all of your software, it matters whether your software will suddenly stop working because you can't re-register it when it decides to demand it, it matters if the product plays nice now but down the line breaks interopability with standards such that it only works with other products from the same company. Just because .NET may work fine now doesn't mean that it is a good business decision - Microsoft's sordid history should be a consideration and it is not unprofessional to factor in a company's past business practices into whether using its current products is a good idea. -

Re:SupercomputersWhy on earth was this modded interesting? The only interesting thing about is the misconceptions that make it possible.
What is the theoretical speed of 0 latency for computations?
(a) The theoretical "speed" of 0 latency is just that: theoretical (or maybe fictitious is a better word). Nothing in the real physical world happens with 0 latency.
(b) So let's talk about when we have a "perceived 0" latency . . . which would mean, umm, operations conducted in units asymptotically approaching Planck time? Or something. Anyway, ridiculously fast. Point is, it stil matters what you're going to calculate. And if you decide to calculate the factorial of googolplex, well, that'll probably still hurt.
(c) But let's posit a machine that does the factorial of googolplex in perceived-0-latency. What's it do with the factorial of googolplex raised to the googolplex power? The point is that you can always describe, in an instant, a computation that is any arbitrary order of magnitude more complex than the fast computation.
(d) so the real question you're asking, what's the speed at which computers become perceived-instantaneous for all interesting problems.
And, of course, the answer depends on what the interesting problems are. I think recent history shows that our appetite for computation actually grows faster than the supply. In other words, the minute someone hands us an "Earth Simulator", we can immediately think of all the cool things we could do if it could simulate at higher fidelity (i.e., do more computation faster). And that'll always happen, because we'll always want to model more complex phenomena with greater fidelity. And, as has also been pointed out on this thread, there are inherent limitations around things like light-speed and the parallelism of a problem (i.e., how many pieces can a problem be subdivided into and how fast do they need to talk to each other drives how far apart they can be and still function). Grace Murray Hopper used to hold up a piece of wire, about a foot long, to show how far apart things could be at 1ns-latency at lightspeed. Some limits are fundamental.

Of course, in Star Trek the computers run immersed in subspace fields that make them superluminal, so . .
