This addresses fundamental routing issues, so my apologies to most of you, however I think some of this crowd needs some clarification (albeit a simplified version):
To all those who are posting such things as "now all I need is fiber to my home" or "I wonder if the Slashdot effect can saturate it" or "how come my ping times to it are so slow?":
You should know that hosts on these networks are generally a mix of globally- and non-globally-accessable. Meaning, many POPs that are "hooked up" to some high-speed initiative like vBNS or Abilene also have "commodity links." Commodity links are normal T3s, etc that are hooked up to a commercial ISP. This makes the site multi-homed, and helps minimize the amount of non-research-related traffic being sent over the high-speed links, because if you want to look at www.cnn.com from, say, a vBNS-connected box, it'll go over the commodity link instead of vBNS.
So the answer is, yes: the Slashdot effect can probably affect GEANT's web site because the Slashdot effect would flood their commodity link. On the other hand, if you were at a GEANT node... good luck trying, and enjoy the pings:)

What happens when one motor fails? The thing will turn in circles and is too heavy to lug around.
you should read the article. You were right in guessing that each wheel has its own motor. however, they are each the backup motor for the other. so if one breaks down, the good motor takes over. same kind of redundancy goes for the dual "sisterboards" inside the chassis that house the logic circuitry.
Gray may have had a very key part in the development of the telephone, but you shouldn't say he "really invented" it. To say that is to discredit the work done by the others I mentioned. If you research the development of the telephone, you'll see there are many brilliant contributers.
The electrical research behind the telephone was done by Heinrich Hertz and Leo Graetz, both German. The invention of the first physical telephone device was done independently by Philip Reis (German) and Antonio Meucci (Italian). The strongest evidence, however, points to a German named Emile Berliner. Alexander Graham Bell never (initially, at least) claimed to have invented the telephone; his patent was for an improvement to Meucci's patented device.
Bell was born in Scotland. Who's the Canadian you speak of? Canadian Reginald Fessenden supposedly invented wireless radio. Maybe you're referring to Bell's claim that he had the idea for the telephone while staying at his Brantford, Ontario home?
If you're so good with Unix systems, why don't you do it (take up the challenge) then?
Because I don't have time. He did ask me to do it, and I said I'd love to but I just coulnd't fit it into the schedule. And I didn't say I was "so good with Unix systems"; I just said I was more comfortable with them than Dan is.
I find it ever harder to believe that you goto school full time, run all these services by your self, and still don't have a clue about unix. If you know this little about Unix you shouldn't be advertising a hosting service. I noticed you offer unix shells as well, what business do you have offering shell services without knowing 2 bits about Unix? Also, if you have all this time to develop "scWeb" why can't you get some books and do this project yourself. I noticed this projectg went from version 1.0 to 3.0 in less than 2 months.
Dan, the guy in question, is a close friend of mine. He works for a consulting company full time, 9-5. He then goes to school from 6-10 at night, taking 18 credits. He's one of the most efficient programmers I know, and is, in my opinion, a gifted site designer. His program went from v1.0 to v3.0 in 2 months because he goes on coding binges that sometimes last days.
The unix shells he offers are on my boxes. Dan is an excellent Windows admin but he isn't comfortable about his skills with Unix. Rather than simply not sell a valuable service, he contracted it out to me. Sounds like good business sense if you ask me, but then again I'm making money on the deal so what do I know?:)
fliplap, reading a couple things on Dan's website and then thinking you can draw all sorts of conclusions about him as a techie or as a person is simply irresponsible.
You may want to learn what Internet2 actually is and why it exists. As stated several times by Stas Shalunov in these threads, Internet2 is dedicated to advancing core Internet technologies, while providing optimized, unsaturated bandwidth for demanding educational and research applications. The engineers of Internet2 are researchers, and one day those same "annoying users" you talk about will be using technologies developed at I2.
I dare you to try. Filing a complaint through ICANN and the WIPO will set you back $2000 in processing fees alone... and thats just to get the WIPO to hear your case; you may not even get the domain back because the squatter can always say he registered it with good intentions.
No, that would be true if this was a Constitutional government.
In reality, government buys whatever it wants because it can, and does, pay for anything on credit alone. Despite our taxes being so high, only a tiny fraction of the government's income is from taxes. Government spends on CREDIT, plain and simple.
Okay I assume most of you here either a) have a KVM and either like or hate it, or b) don't have a KVM but might consider buying one but don't know which to buy. I'm going to tell you what you should look for. And by the way, Tom's guide (as usual) is dreadfully incomplete.
Some switches are mechanical, and others are electronic. Most electronic ones are better because they feature some kind of "emulation", meaning that when you switch off one machien to another, the machine you switched FROM still thinks the mouse and keyboard are connected when the OS polls the ports. On mechanical KVMs, they won't see anything and will sometimes b0rk.
However, not all emulating electronic KVMs are created equal. Belkin, Aten, Linkysys... they all have the same fundamental flaw: they have only one microprocessor trying to handle the emulation requirements of all the ports on the KVM.
One of the best switches you can possibly buy is a Raritan. They have a dedicated microprocessor for each port.
I have tried using a Belkin Omnicube and an Aten Masterview with a very simple setup: one Windows XP box, and one FreeBSD or Linux box. With both switches, XP worked fine but with FreeBSD, you get (at best) errors from the kernel about how the mouse is out of sync (psmintr....). With Linux, I could only get it to work if I used a standard PS/2 Microsoft Intellimouse with the gpm and X driver settings set to "PS/2". If I wanted to use "IMPS/2", I had to kill and restart GPM every time I switched back to Linux. And neither Linux nor FreeBSD would even RECOGNIZE my Microsoft Optical Intellimouse with the USB-to-PS/2 converter on the end... although I reiterate that XP worked just fine.
Raritans, on the other hand, work flawlessly in any situation. They JUST WORK. I'm currently waiting for my new Raritan to arrive in the mail. They're slightly more expensive, but totally worth the money. And for those of you who are sysadmins for larger-scale projects, consider Raritans for those racks because they make rack-mountable KVMs with up to 12 ports... we used them at Internet2 and they work perfectly.
My priorities are where they should be... focused on me. Like everyone else, I am deeply saddened by the events of 9/11, and I think sorrowfully about it at least 30 times a day, but I am not letting it consume my life. I have not quit school and work so I can go on a 24/7 worry binge.

Notice how the towers fell straight down, instead of toppling over and taking out nearby buildings.
My girlfriend is a civil engineering student, and they discussed the attacks in her Structural Engineering class yesterday. Apparently, the guys who designed the towers should be very proud. In a worst-case scenario, fires would (as they did) cause the steel structures to melt. The towers were designed so that, in that worst-case scenario, they would implode straight down instead of falling over.
Some people blame Microsoft for the world's computer security problems. After all, if Microsoft cared a whit about security, the virus outbreaks wouldn't be so damn nasty. Others say Microsoft isn't the problem; networks are inherently insecure (see the EROS Project for a solution in development). I'm not one to say Microsoft is totally to blame, but I would like to quote Stanley Kubrick's Full Metal Jacket on the issue:

The thing about Michael Bloomberg is, he really does suck. He's chairman of the board of trustees at my school (Johns Hopkins University) and he does shit like, make anonymous donations even though everyone knows it's him, on orders that the money be spent for shit we don't need (like brick walkways, instead of, say, student services or online course registration). Plus, the school insists on naming everything after him: so far, we have the Bloomberg Center for Physics and Astronomy, and the Bloomberg School of Public Health.
And now he thinks he can become mayor of NY. ~sigh~
