I went with the middle-A=440 Hz standard. Then, half-step up to Bflat with 2^(1/12), then divide by 2^57 to go down 57 octaves. Flip (1/x) to get the period, and start dividing to convert seconds to years. The original journal article (see another comment) says 9.6 million years, which is actually 0.35 half-steps sharper than Bflat, but still 0.65 half-steps flatter than B, so it's closer to Bflat.
One of the authorsposted a link to the original paper. They say that the amplitude of the ripples is about 20-30% of the X-ray brightness. I don't know what density variations that corresponds to, but it sounds huge. The amount of energy carried by the wave would be correspondingly huge.
Yeah, what he said. None of the articles I read actually gave the frequency or the period of the oscillation. They did say it had been going on for a billion years or so.
I think it comes in useful when dealing with instruments whose key is not C. It makes transposing the key easier. In the final form, I guess they would be converted to the "actual" notes.
...the intellectual property of most companies is not visible enough to "protect". You can't avoid assimilating that which you by definition cannot recognize.
I wish I had mod points left. Very insightful. Of course, this problem isn't open-source specific. It's just easier to *catch* the open source violators because you can see what they have. It probably happens in proprietary software all the time without anyone being the wiser, as no one (who would expose it) has access to the current and potentially copied source codes.
Believe me, I've pondered string theory. The basic problem I have is that in order to really get a physical theory, I have to fully understand it from the ground up. Most of the people who are smart enough to get string theory are terrible teachers. So all that's left is bad books. These are either written for normal people and leave out most of the details I want, or they are written for specialists who are being guided by an expert who can answer their questions. I'm neither. I'm a PhD physicist who doesn't have any string theorists around to ask questions to.
By the way, there are only the modes you described for a non-linear triatomic molecule. The number of modes is equal to 3*N (where N is the number of atoms), and there are always 3 translational. Linear molecules have 2 rotational, while non-linear molecules have 3 rotational. The rest are vibrational.
Nothing like a discussion about a physics topic that most physicists don't understand. If you poll 50 PhD physicists, most likely *none* of them really understand string theory beyond what Brian Green writes in his books indended for the public.
There was a recent article in Science magazine talking about the effects of hydrogen on the stratosphere. For their purposes, the source of hydrogen and/or water would be waste from hydrogen fuel cells and leakage from hydrogen transport systems. Both noctilucent clouds and ozone depletion are mentioned in the abstract.
But if somebody is concerned about the emissions from a few Space Shuttle launches, imagine what cities full of hydrogen-powered cars would do.
Of course, the download gives Blaster plenty of time to worm its way in before the actual patch is applied. Luckily for me I was behind a firewall when I had to patch an open Win2k system this past week.
I discovered a few months into it that whenever I would connect AC power to the laptop (while running off batteries) the system would begin to "skip".
The moment I put in batteries while AC is connected, the unit freezes hard and must be restarted.
Strange. I'm having the exact same problem with an IBM T20 laptop. Whenever I try to run off the AC while it's charging the battery, it freezes up. If I boot off battery then plug in the AC, it's okay. If I pull the AC, it freezes.
Sometimes during these lock-ups, I can hit the volume or "ThinkPad" button, and it will run a few cycles, then freeze again. Sometimes it will unlock. And all of this may be related to a BIOS upgrade in a failed attempt to get WinXP running.
If you find a solution to your problem, make a post here or let me know or something. I may be experiencing the exact same thing.
It takes a lot of money and effort to set up a distribution network for a software company. RedHat, SuSE, etc. are providing this service for FREE. Each additional copy of Linux (not GNU/Linux, because SCO only claims rights on the kernel) is another potential $700 for SCO. The more that are passed around, the more potential money SCO can make. Heck, SCO should be paying the Linux distributors for the additional revenue stream. The downside is that only a small fraction of the users will actually pay the money.
On page 47, near the end of Chapter 2, the report states:
So eager was the general public to turn in pieces of potential debris that NASA received reports from 37 U.S. states that Columbia's re-entry ground track did not cross, as well as from Canada, Jamaica, and the Bahamas.
The ground track did cross 7 states (including LA), so that leaves only 6 states where everyone was smart enough to keep quiet.
This document has some beautiful photos of Columbia and Challenger in it, especially at the beginning of each Part. These pics are add a nice memorial feel to the report, in addition to the let's-not-let-it-happen-again tone.
In the CNet interview, Mark Heise says, You're not going to see "copyright, The SCO Group."
Well, there is a copyright claim under their old name. In my kernel source v2.4.20, the files drivers/net/tlan.c and net/ipx/af_ipx.c both claim all or part copyright by Caldera!
I tend to agree with Linus. They're smoking crack.
I wonder, isn't there some requirement for a plaintiff to try to resolve a dispute *before* going to the courts? By refusing to let the kernel developers fix the kernel, they're insisting on the infringement rather than trying to fix it.
SCO CEO Darl McBride was going on a family vacation to Hawaii when the RedHat suit and IBM countersuit came up. Gee, it's too bad the nice man's free time was ruined by corporate litigation.
Oh, wait, many people develop Linux in their free time...
These devices could serve as a communications system to get information to/from special forces soldiers during covert ops. With a guaranteed friendly receiver within maybe a mile, an extremely low power could be used for the soldier to transmit. Add encryption, compression, and a high bandwidth, and only short, un-sniffable, non-locatable transmissions could be used. The "Pringles cans" would even lay down a base of inteference so that actual communications would be impossible to spot.
The function of a single can would be some combination of:
if a friendly base is within range, establish a link
keep a network going with neighboring cans, passing data around as necessary
listen for friendly communications to forward
listen for hostile comm. to intercept
jam hostile comm.
act as a smart mine in case of enemy tampering?
Maybe they could even have solar cells to make them last more than 2 months in the field.
Apparently the cell service of at least one company didn't actually go down when the power went out. Verizon Wireless issued a Press Release stating that it was just a huge demand that made calls not go through. They do admit there may be "isolated outages" "because of back-up power limitations", i.e. they ran out of gas.
The picture detail from light isn't nearly as good as from electrons. In electron microscopy, you can (barely) see the positions of individual atoms, which are a few Angstroms apart. Laser light has a much larger wavelength (>1000 Ang) and hence gives less resolution.
I had to do that back in '93 on a Seagate SCSI drive. Luckily I had several of them, so I didn't have to buy one to get the working circuit board. I got my data off the one and then put the board back to into the "donor". So in the end I only lost one drive but not the data.
The hard way is opening the drive in a cleanroom and reading the data off manually with a scanning head. That's why they charge thousands for that service.

What's the error on the frequency of the note?
Yeah, what he said. None of the articles I read actually gave the frequency or the period of the oscillation. They did say it had been going on for a billion years or so.

At least it would compress well. Especially if expressed as a MIDI file.

Yeah, I saw ALSA as well. I'm glad I could still get my drivers, but I guess the inconvenience would have been part of the protest.
Texas, Jamaica, they're close, right?

Could that be an unauthorized public performance of someone else's copyrighted work?

I have no idea of the extent, but I would have thought that cellular services would have backup generators. It really upsets me that they don't.
