A comet's orbit is defined by the same laws as any other. Some comets (primarily "long period" comets) do travel remarkably fast as the progress through the inner solar system (but at the same time progress quite slowly through the outer solar system). Others don't (Comet Eike comes to mind). And, no the "yank" won't affect the comet measurably at all -- consider the mass of the comet and the mass of Rosetta, and you'll realize it'd be analogous to a fly pushing off against your arm. Christopher A. Bohn
Aside from the near-difficulty (read "impossible" without Star Trek engines or a couple centuries of lead-time) of being able to shift a comet's orbit enough to force an intercept with the Earth, would you want to be responsible for providing the precise delta-vee to place it in an orbit about the Earth? And how about orbit-keeping adjustments to keep the orbit from decaying? Christopher A. Bohn
The problem is "nongravitational accelerations" -- a comet's orbit, unlike most other bodies in the solar system, changes from orbit to orbit. The outgassing provides accelerations that subtly change its orbit. While accelerations so close to aphelion have less effect than if they were near perihelion, they still make it difficult to precisely predict its next orbit. This should only raise a concern if it was already going to be passing close to the Earth in one of its future orbits -- the change is too subtle to cause drastic shifts. Christopher A. Bohn
We saved the French from the Germans in WW2 for the same reason the Germans conquered Belgium in WW1 -- they were along the way. =) Christopher A. Bohn
The reason the Prime Meridian is where it is is because of the Greenwich Observatory, considered at the time to be the astronomical observatory. It wasn't because England wanted to be the world's center of culture, it was so that when an astronomer anywhere in the world noted the time of an event, it could easily be converted to the precise (as in not-off-by-even-one-second) time at a major observatory.

PDF is not a collaborative format -- that is, while we can all write in the format (with appropriate plug-ins for our word processors), and we can all read in the format, we cannot use a typical word processor to edit a PDF document someone gives us. Christopher A. Bohn
The question here is not the quality of the product. What we are dealing with here is the philosophy of free enterprise. BMW or Yugo, they have the same rights under free enterprise. And at those times the government decides it needs to limit free enterprise in a specific instance to encourage free-er enterprise on a general scale, then both BMW and Yugo would have the same responsibilities.

I am betting that it is BEOS plus the GNU parts of Linux i.e. everything but the kernel. They just threw in the word "Linux" to be buzzword compatible
If this turns out to be the case, I think we need to retain a roof-repair contractor since RMS will hit it. As much as he's been fighting for the prefix "GNU/" whenever someone refers to an operating system with the Linux kernel and GNU components, I can just image the color of his face when someone uses "Linux" to refer to the GNU tools and not the kernel!

If you provided a separate channel for left & right eyes, then you could have stereoscopic vision. Slap on a couple data gloves. Have the computer project an image of a virtual keyboard in front of you. Touch type (or hunt 'n' peck). Now there's an image as people walk down the street. Christopher A. Bohn
The article says it simulates viewing a 52" TV from 6.5' away. Correcting my math for 78" separation, this is the same as a 12" monitor (albeit with very high resolution). Christopher A. Bohn
I power-down my Linux box at night since I have no need for it to be on when I'm not using it (it's not a server for anything), and I'd just as soon not pay for the extra electricity (disregarding environment issues). I'm sure many other do the same. Christopher A. Bohn
I expect this will show up during the initial power-up, not as a part of the OS load. For example, your computer's brand name, or an "energy-star compliant" logo often show up now, usually disappearing just before the memory test. Christopher A. Bohn
Anyone think code from the pgcc fork will get re-integrated into gcc 3.0? IIRC, it does include some support for AMD processors, too. Christopher A. Bohn
You wouldn't need multiple versions of gcc -- just provide more allowable arguments for the existing command-line arguments for gcc. gcc -m=cpu -march=cpu Christopher A. Bohn
Except that GPL does not require that Intel distribute its gcc-related work outside of Intel. So they could have simply continued to keep it inside Intel (no pun intended) and used it to show what their processors could do. Christopher A. Bohn
And how about AMD-specific tweaks for the Linux kernel? The recommendation that we configure for i386 for AMD processors (including K6-3! and presumably K7!) makes me hesitate as I consider my new box. Christopher A. Bohn
This was filmed in 1997, and supposed to air last year. That's why there's no iMac. I think the other reason it ended where it did was because that's a good poetic note, with BillG looming over Jobs on the big screen just like Big Brother in the 1984 commercial. Christopher A. Bohn
They also played a little with some facts. For example, Apple getting WIMP from Xerox PARC (the leading technology center for everyone but Xerox) was completely above-the-table, with stock gifts, etc. It was kind of "okay" IMO. When it ended, I felt like there was still another hour of the show -- that's my big complaint, that it fell flat at the end. And, frankly, I'm surprised those NECs were shipping with Windows 1.0, since my first taste of MS Windows (2.something) was that it was a horrible piece of wasted bits -- even Windows 3.whatever was a vast improvement.

Sometimes it's less expensive to buy a nodes pre-assembled. Sometimes it's necessary because of the particular fund the money's coming from (a system I built was in this boat -- about a fourth of our money came from the "desktop computer" fund). Sometimes it's a question of effort -- they'd rather not spend time physically assembling the nodes. Christopher A. Bohn

You're right. I mixed aphelion & perihelion.
Christopher A. Bohn
to keep it from bouncing off. The comet just doesn't have enough gravity for a traditional soft landing.

Diskless nodes is a path many take when they build Beowulf clusters -- makes it easier to replace nodes &/or expand the cluster.

Sometimes it's less expensive to buy a nodes pre-assembled. Sometimes it's necessary because of the particular fund the money's coming from (a system I built was in this boat -- about a fourth of our money came from the "desktop computer" fund).
