Well the DOS PGP.EXE binary should do (no need for source, as it is uses keysizes greater than allowed by ITAR already, so ability to increase key sizes is not required for ITAR applicability). It's 94k pkzipped. Front and back print on a T-shirt would give you 80k. You could probably tweak something to get it on a shirt. Dunno if it would read printed on a shirt. It would be fun to see what it looked like a sheet of paper tho'. Anyone happen to have code to do some of these 2d barcoding things? Or are they all proprietry? > >If the CJR for the t-shirt is ultimately denied, ditto? > > That would be much better. More free publicity.

Is that what you meant, that "this shirt is a muntion" is misleading? The "has been classified" was wording that Don Henson used in his earlier ads, but did not appear on any of the shirts (AFAIK). Joel Furr's shirt says: THIS SHIRT IS A MUNITION Don Henson's says: WARNING THIS SHIRT IS A MUNITION My shirts say: WARNING THIS SHIRT IS CLASSIFIED AS A MUNITION AND MAY NOT BE EXPORTED FROM THE UNITED STATES, OR SHOWN TO A FOREIGN NATIONAL I think Raph sent them one of Joel's, so it says "this is shirt is a munition", rather than "...has been classified...". Perhaps some people think that this too is inaccurate?

Need Mail-to-News gates
by bluebird＠alpha.c2.org 17 Dec '03

17 Dec '03

Could someone PLEASE netmail me some _known reliable_ gates that use the straight netmail address format (alt.whatnot(a)bosco.kollege.edu)? All of the old reliables are shut down and none of the ones listed in the last remailer helpfile I got work either: group.name(a)news.demon.co.uk group.name(a)dispatch.demon.co.uk group.name(a)bull.com group.name(a)cass.ma02.bull.com group.name(a)paris.ics.uci.edu group.name(a)crs4gw.crs4.it group.name(a)berlioz.crs4.it group.name.usenet(a)canaima.Berkeley.EDU NONE of these work, or were nonfunctional when I tested them, anyway. I use the other gates like mail2news(a)utopia.hacktic.nl with the Newsgroups: field format, but the straight address format is useful for some other purposes. Thanks.

Worst case scenario -- you write down the seed, and when the police break down your door, they find that you've written it down. Well, if things have progressed to that point, you're in pretty serious trouble anyhow, and if you're expecting this to happen you have a simple remedy -- back up & encrypt your wallet rather than writing the seed down. Or, put the seed in a little text file, encrypt the text file, and back it up. I suspect, however, that this means that the Digicash wallet doesn't pick up new bits of entropy to "groom" it's random state. Also, it was unclear where this state came from, but it's hopefully not just text entered by the user. (I could see getting the state from something like keystrokes or mouse clicks, then having the user write down a checksummed, error-corrected string as a preferred alternative.)

groupware position available in Boston
by Vladimir Z. Nuri 17 Dec '03

17 Dec '03

I recently got word of an interesting groupware development position in Boston that someone here may be able to benefit from. feel free to pass on this info. (contrary to some here who are not impressed with groupware application potential, in my estimation groupware is soon going be a key "killer app" in cyberspace, perhaps the "next" one after Netscape, driving key technological advancement in network & software development... in my opinion virtually every significant and valuable aspect of the internet can be boiled down into a subset of the functions of groupware.) === From: mike(a)kni.mv.com (Mike Hren) ... We are starting a company called Emergent Systems and are looking for technical partners to help turn our vision into reality. We're developing a meta-groupware application that seeks to accelerate the learning of a workgroup. Called a Discovery Acceleration System, the idea is to use a text engine to synthesize the collective email dialogue (voicemail later) of a workgroup into its core concepts (Concept Map) that can be visualized, hypertext linked to related information sources, and used as a prioritizer of unsolicited email based on conceptual relevance. Just as knowledge is born of chaos, this Concept Map emerges from the workgroup's daily interaction--as opposed to being externally defined by a static knowledge base. In a dynamic sense, since the Concept Map is used as a distributed Linker and Lens between workgroups, it also enables a system of interaction to emerge at the organizational level. We are looking for someone with software development experience, and interest in information retreival, data visualization, groupware, or messaging systems. Since most of the components of this system are commercially available, integration is more important than theoretical development. Also, a desire to be part of a start-up effort is a must. .... If you or anyone you know might be interested, please email a resume and description of interest. Thanks for your time. Mike Hren President Emergent Systems, Inc.

POINTER: The Money Laundromat
by Damaged Justice 17 Dec '03

17 Dec '03

J. Orlin Grabbe's essay, "The Money Laundromat", as published in the November 1995 issue of Liberty, was sent to me via e-mail by someone who prefers to remain anonymous. After checking for accuracy against my own hard copy, I have posted it to the following Usenet newsgroups: alt.security.pgp alt.society.sovereign alt.society.anarchy talk.politics.crypto I will be making this article available on my Web page shortly as well. The article covers both the threat and the promise of digicash, with much detail devoted to electronic surveillance and financial tracking via PROMIS software. This single paragraph summarizes rather well: "...the coming battle over financial footprints is inevitable, and perhaps inevitably bloody. But in the end it is the money laundering regulations that will have to go. For one thing, advances in the technology of anonymity are putting financial privacy within the reach of everyone. For another, there is a growing awareness that the existing laundering statutes have little or no effect on terrorism or drug-dealing, but instead are related to an upswing in government-sponsored harassment of targeted political groups." -- http://yakko.cs.wmich.edu/~frogfarm ..for the best in unapproved information S..O)....
