Not necessarily. In both the magentic pendulum and chaotic pendulums this is not a problem. Jim Choate ravage(a)ssz.com

Steve Jackson Games (SJG) was raided by the Secret Service for that game, in which the Secret Service showed their total ignorance of computers by mistaking it for a "handbook of computer crime." Since they're the ones also concerned with counterfeiting: A. this indicates something about how much one needs to worry about counterfeiting, and one reason that even with the new changes, US currency is still one of the easiest ones to counterfeit with modern technology. B. they're likely to be total idiots when it comes to digital cash On the other hand on the last point, they did look at one private currency scheme and deem it allowable, since the (physical) bucks in that case didn't resemble US currency. The governmental group that _did_ have problems with it was the SEC, who decided that since its non-inflationary qualities were based on direct funding through a group of investments, it qualified as an unlicensed mutual fund. Moral of the story: don't base it in the US, or don't make it run off of investments. -Allen

I believe that all of this comes down to what and when is the "waveform collapse" - what and when is observation. If any interaction with something else counts as observation, then it won't work. This problem is where one gets into the many worlds hypothesis et al. -Allen

Another way of thinking of vacuum noise >is that amplification mixes the state of the signal, with the (unknown) >phase of the universe at infinity. I would think that the action of a optical fiber amplifier is, in a sense, "negative loss," or the inverse of the kind of loss normally found in a fiber cable. Thus, if quantum crypto can be done through a long fiber at all, the fiber amplifier shouldn't negatively affect it. However, if polarization is important (and I know that "polarization maintaining" fibers are available) then I assume that the amplifier would probably also have to be designed to ensure that polarization would also be maintained through the EDFA (Erbium-Doped Fiber Amplifier.)

Your email >address is in the message sent, regardless of what netscape thinks >your identity is. Sorry for the imprecision here. I was referring to Netscape 2.0 on unix here. Changing the email address known to netscape is insufficient for non-root users on unix systems, because sendmail will put your real address into the headers. The auto-responder used by the posted example page apparently isn't sophisticated enough to extract the real address, but the address is still in the headers for someone to extract. For those who haven't read the script, the technique used is as follows. A java script sends a mail message to the author of the script. The identity of the sender is in the mail headers. The script does not look at netscape variables or otherwise get the information from netscape or the environment. The major point is that setting a bogus email address in netscape will not necessarily prevent your email address from being captured in this manner. Mike

Public Access Obsolete. Capitalism offers free email
by Duncan Frissell 17 Dec '03

17 Dec '03

The NYT's Cybertimes reports (http://www.nytimes.com/library/cyber/week/0219email.html) that two companies are preparing to offer free email to customers who agree to be barraged by ads. Juno and Freemark will soon offer free email to all (Americans). http://www.freemark.com/freemark.html http://www.juno.com/ And since you can do (almost) anything with email that you can do with the rest of the net (just more slowly and less conviniently) I guess we don't have to worry about government-provided public access any more.
