All experiments make simplifying assumptions. Sometimes they make the wrong assumptions, but that doesn't necessarily mean the assumptions are faulty. It is simply the result of the complexity of the problem.
Seti@Home decided to focus on part of the problem.
They decided to look for intentional transmissions to other intellegent life , not cell phone calls & other artifacts of civilization like computer noise (jesus christ, where do you get this shit).
They have to start somewhere, don't they. They can't very well start looking for transmissions methods that humans dont' know about and they can't look for transmissions using methods which we can't hope to detect.
Personally, I think it reasonable to go after lowest common denomitator communications.
A lot of people are getting worked up about the tone of the SETI guy in the wired article.
Keep in mind, this article is a news *story*. Like all news storys, it is designed to try and get a reaction out of the reader. This one is clearly constructed to insite your outrage.
Well guess what, it looks like it worked you have been manipulated by the media.
I can't be sure, but I bet if you had the full text of the interview, or if you talked to the guy yourself (please, don't try, he obviously has enough to deal with) you might feel differently.
Wait, I know, Linux uses HLT, saving power. Too bad your hard disk, RAM and power supply are still burning up significant wattage.
Oh, wait, you would be cracking RC5 keys. Can you say boring?! Can you say, it was an interesting project the first time but it isn't any more?
Get over it. Get over the perceived slight against UNIX & Linux users, it was a general comment. I don't see how you could take it personally unless a) you are cheating, b) you have a big chip on your shoulder.
If you are cheating, shame on you! If you have a chip on your shoulder, keep in mind that this guy is probably a UNIX/Linux type of guy. They are using UNIX on their back end and they are trying to do big science on a small budget.
On the subject of publishing source. I think their concern about doing what they can to eliminate tampering is a valid one. There are various ways to deal with it, but they are obviously resource constratined. Ultimately though, they are trying to do real peer-reviewed science, so you can be sure that even if they don't publish the source, they will describe it in great deatail and provide a lot of background on how it works and why they did things the way they did.
I really agree with this. Until now, I have viewed these Red Hat deals as good, over all.
I guess I still do, supporting one Linux Distro makes it that much easier to support other Linux distros.
I hope that ISVs will realize that supporting only one Distro is bad for their linux investment. If they help balkanize the market then the market will not grow as fast as it could, making their upside considerably less than it could be.
The Alpha fabs that Intel acquired and are bound to produce alphas on aren't that attractive. They are little more than a buffer for DEC/Compaq at this point. Samsung has taken the lead in manufacturing Alphas.
Must be why they build 16-way alphas with huge I/O bandwidth. The floating point may be wasted, but it is the only chip Digital had that could play in the high end.
I really doubt that NT is what is keeping the Alpha alive. Compaq, & Digital before it, have intel boxes that play at the level where NT sits. If anything, the Alpha has been around this long because they still need it to compete with Sun, HP and IBM in the big computer business.
First, a couple of years is a long time in the networking industry. More impressive first products have been engineered in that time frame.
Second, don't be missled by claims that something is done in hardware. As often as not, this does not mean that the entire implementation is burned into silicon. Often it only means that processing that may have been done on the main CPU has been shifted to a dedicated processor. Often times this dedicated processor may be particularly well suited to the task at hand because it implements special instructions. It may also be on the same die as other discrete functional units dedicated to the task (like an ethernet controller).
What you end up with can be quite fast, but it still retains a bit of flexibility, so it can be reprogrammed to fix bugs, or meet new standards. (or something totally unrelated. Appearantly the engineers at Alteon programmed the MIPS CPUs they use in their gigabit ethernet switches (two per port) to crack RC5 keys for a laugh.)
Um, it is equally possible it doesn't suck. What is a "DOS loophole" Open source would be nice, but it doesn't necessarily determine the success or failure of this card. I think the amount of money they can put into marketing and distribution is a bigger issue.
So, perhaps we should drop hardware FPUs too and put that silicon into improving integer performance?
We will have to see, but I think things like AltiVec and KNI are probably a wise use of silicon in that they can improve the performance of some of the most computationaly intensive tasks likely to run on a microprocessor these days.

Besides, if they can do 5.5 MB second sustained then that is enough for a single DV stream.
If you are aliasing root e-mail to another account in order to receive editorial submissions then I think you are better off picking another name, like editor, or something.
Unless, of course, you think it looks cool to use root, in which case you should consider that it might look really lame to others.
In any case, I think it is great that someone took the initiative to get this going.
Man, I would love to run Beowulf on one of these.

Get your facts straight and calm down.

The closest star is far less than 100 LY away. Why bother doing the math if you don't bother getting good numbers.

I don't get the fuss about waste.
What would your CPU do otherwise?

I don't follow your logic.

Sorry, I couldn't resist.

Do you know the difference between a server and a workstation? Didn't think so.
The 4-way Intel machines you are talking about absolutely pale in compairison to the 10+ processor Alpha machines the previous poster is referring to.
Or perhaps you were thinking of the NonStop servers Compaq sells. These were the result of its acquisition of Tandem and use MIPS chips.
Must be why they build 16-way alphas with huge I/O bandwidth. The floating point may be wasted, but it is the only chip Digital had that could play in the high end.
I really doubt that NT is what is keeping the Alpha alive. Compaq, & Digital before it, have intel boxes that play at the level where NT sits. If anything, the Alpha has been around this long because they still need it to compete with Sun, HP and IBM in the big computer business.
Anyone who would pay money for one of these to keep them out of Carmack's hands is a complete and total looser.
Well, have you?
Ever heard of switched ethernet?

I think that is more an issue of the mechanism used, which is still an important consideration.

Just think of how fast it could break RC5! d00d!
Just seems like a bad idea to me.
