computers like the earth simulator go vastly under utilized for the most part
From first-hand experience, such computers are running jobs almost 24x7. Due to job scheduling details there are times when some of the machine is idle, but this is still a small percentage. These machines are used for a vast array of applications, not just the advertized ones.
Now the utilization as a percentage of peak theoretical is another matter. For some algorithms, 20% of peak performance (IIRC) is considered good (ie. a particular code might only get 2 TFlops on a machine rated for 10).
The interconnects are (usually) not commodity parts -- just the servers.
As an example, the first IBM SP "supercomputers" were essentially just common Power workstations bolted into racks, but connected with a custom made SP switch.
Nevertheless, EarthSimulator has shown what can be done by designing the entire server from the ground-up with the application in mind.
20. Although it completed an initial public offering, SCO has failed to create a successful business around Linux.... In fact, the company as a whole did not experience a profitable quarter until after it abandoned its Linux business and undertook its present scheme to extract windfall profits from technology that SCO played no role in developing.
21. In an attempt to revive its faltering Linux business, SCO aquired Original SCO's rights to UNIX and undertook "the unification of the UNIX and Linux operating systems." To that end, SCO markets and sells a number of UNIX products. [...] Like SCO's Linux business, however, this enterprise is failing. With apparently no other prospects, SCO shifted its business model to litigation.
22. SCO devised a scheme to profit from the UNIX rights that it aquuired... though UNIX was in no way developed by SCO... SCO undertook to create fear, uncertainty and doubt in the marketplace...
23. Recognizing that there is little value in its UNIX rights, SCO did not limit its scheme to that technology. Rather, SCO devised and executed a plan to create the false perception that SCO holds rights to UNIX that permit it to control not only all UNIX technology, but also Linux -- including those aspects generated through the independent hard work and creativity of thousands of other developers and long distributed by SCO itself under the GPL.
This is why I think that all sub-standard open source mail servers should be outlawed in favor of Exchange 2000, which in coordination with Active Directory is the only messaging solution which supports a PKI (Public Key Infrastructure) whereby sources of email can be authenticated by the sender's trusted certificate, and if necessary blocked.
Now why the hell wasn't this moderated as funny?
The poster was kidding, right?!
[Although I do agree that SMTP needs to be replaced entirely]
wonder what kind of bandwidth one needs to do the whole 640x480 thing at a decent frame-rate?
With iChatAV I was using about 50KBps in both directions. The video is pretty good, but the audio sometimes cut out.
FYI, I had some trouble getting it to work at first. After opening my firewall to AIM and restarting iChat everything worked flawlessly -- don't know which was the fix.
UI wars aside, KDE 3.1.2 still has an obnoxious bug. Please vote and/or comment at the given link.
KDE is IMHO awesome, but its habit of automatically switching focus to error dialogs on another desktop is driving me insane. Especially since, statistics aside, the switcheroo invaribly happens when I'm writing a Slashdot post, and in my furor hit "enter" just as a warning dialog comes up.
-- Just another 2 minutes that I should have been writing my thesis.
I assume you are talking about the black circles around the front? I have a feeling that these are RCS thrusters and windows -- although the webserver died before I could investigate any further.
Or, better yet, get down and dirty and start reverse engineering products and coding your own open source drivers.
Unless you live in the USA in which case reverse engineering could get you thrown in jail -- because congress is sure that by reverse engineering you must either be a terrorist or a thief.
What the fuck: I can purchase 1,000 rounds of 30-06 ammunition, along with a few pounds of power for reloading, but they think that a few Estes model rocket engines are dangerous.

Ever pay for VPC? $250 -- $200 of that is for the Windows license. MS didn't cut Connectix any deals.
Of course you _could_ buy the $50 DOS version and install your own copy of Windows. I expect that version to be discontinued real quick. Or to include a "free copy of Windows" -- for $250.

Given MS's history, I think it is a safe bet that this will be a _bad_ thing for VirtualPC Mac.
At the very least, I fully expect one to be required to purchase it with a Windows license.
I personally think VPC (all platforms) will go away entirely.

someone makes a worm that downloads and installs a Linux distro?
If the development tools were as good as Visual Studio I'd probably switch entirely
Have you checked out XCode ?

This is officially known as the "loose nut behind the keyboard."
The irony is they probably used software to come to that conclusion.

Not sure if this is the website, cut it does have the complete text on-line of Wilkins "An Essay Towards a Real Character..." Also see this summary.
Anyone find the "Rosetta Stone" chart that he mentioned on his website in the (600 page) essay?
Congrats to Todd!

Ah, but that would require thought, courage, and change. Ever meet a record executive?
Nice idea though -- as a consumer I like it.
Hum. Linux seems to support "coma" all too well on my laptop.

Ink is the only thing that HP makes money on these days. I wouldn't be surprised if inkjets become disposable soon. Gillette has this racket down pat.
