As the Department of Health is supposed to be sending this report to people who ask for it attempts at restricting distribution would be absurd. I've skimmed it - fairly boring - but I could understand Zergo being embarrassed.

The Kodak disposable camera I have in front of me says "Kodak, Fun and Gold are trade marks." and "(c) EASTMAN KODAK COMPANY, 1994" while I have 361 references to Gold, dated 1611, and it was very likely an old word then.

Decay, rather than fission, I suppose. I believe there's a treaty prohibiting nuclear weapons in space. Not so surprising if they're inpractical - political points for nothing. Bill Frantz: >I think this comment is in error.

Replacement of tritium is certainly the dominant need. As for the decay products - it depends how close they get to pure 239. Half-lives: (years) Pu 238 89 Pu 239 24000 Pu 240 6500 Pu 241 15 Pu 242 400000 D 0.015 T 12.3 Paul Pomes wrote: > >Even a fizzle with a yield in the hundreds of tons equivalent is respectable. >Plutonium decay products have a high neutron cross-section and steal the >fast neutrons necessary for the chain reaction to build.

The only books I have to hand contain _thermal_ cross-sections. :( If it's an H-bomb I was under the impression you don't care that desperately about the size of the plute yield - only that it is enough to start the fusion. Anybody know what happened to the proposed fissionless H-bomb of the '60s ? Presumambly it never got working. Warm&ComfyMonger

Bill Of No Rights
by Bill Frantz 17 Dec '03

17 Dec '03

I thought you would enjoy: ---------- Forwarded message begins here ---------- Bill Of No Rights The following was written by State Representative Mitchell Kaye from Cobb County, GA We, the sensible people of the United States, in an attempt to help everyone get along, restore some semblance of justice, avoid any more riots, keep our nation safe, promote positive behavior and secure the blessings of debt-free liberty to ourselves and our great-great-great grandchildren, hereby try one more time to ordain and establish some common sense guidelines for the terminally whiny, guilt-ridden delusional and other liberal, commie, pinko bedwetters. We hold these truths to be self-evident, that a whole lot of people were confused by the Bill of Rights and are so dim that they require a Bill of No Rights. ARTICLE I: You do not have the right to a new car, big screen TV or any other form of wealth. More power to you if you can legally acquire them, but no one is guaranteeing anything. ARTICLE II: You do not have the right to never be offended. This country is based on freedom, and that means freedom for everyone - not just you! You may leave the room, turn the channel, express a different opinion, etc., but the World is full of idiots, and probably always will be. ARTICLE III: You do not have the right to be free from harm. If you stick a screwdriver in your eye, learn to be more careful, do not expect the tool manufacturer to make you and all your relatives independently wealthy. ARTICLE IV: You do not have the right to free food and housing. Americans are the most charitable people to be found, and will gladly help anyone in need, but we are quickly growing weary of subsidizing generation after generation of professional couch potatoes who achieve nothing more than the creation of another generation of professional couch potatoes. ARTICLE V: You do not have the right to free health care. That would be nice, but from the looks of public housing, we're just not interested in health care. ARTICLE VI: You do not have the right to physically harm other people. If you kidnap, rape, intentionally maim or kill someone, don't be surprised if the rest of us want to see you fry in the electric chair. ARTICLE VII: You do not have the right to the possessions of others. If you rob, cheat or coerce away the goods or services of other citizens, don't be surprised if the rest of us get together and lock you away in a place where you still won't have the right to a big-screen color TV or a life of leisure. ARTICLE VII: You don't have the right to demand that our children risk their lives in foreign wars to soothe your aching conscience. We hate oppressive governments and won't lift a finger to stop you from going to fight if you'd like. However, we do not enjoy parenting the entire world and do not want to spend so much of our time battling each and every little tyrant with a military uniform and a funny hat. ARTICLE VIII: You don't have the right to a job. All of us sure want all of you to have one, and will gladly help you along in hard times, but we expect you to take advantage of the opportunities of education and vocational training laid before you to make yourself useful. ARTICLE IX: You do not have the right to happiness. Being an American means that you have the right to pursue happiness - which by the way, is a lot easier if you are unencumbered by an overabundance of idiotic laws created by those of you who were confused by the Bill of Rights. ------------------------------------------------------------------------- Bill Frantz | Internal surveillance | Periwinkle -- Consulting (408)356-8506 | helped make the USSR the | 16345 Englewood Ave. frantz(a)netcom.com | nation it is today. | Los Gatos, CA 95032, USA

The tritium used in thermonuclear weapons has a much > shorter half life, and would need to be replaced about that often. Since radioactive decay is first-order, the following equation applies: N = N exp(-kt) 0 where N=amount of material at time 't'; N = amount of material at time t; k=decay rate constant; t=time of interest. The decay rate constant (k) for first-order decay processes can be expressed as k = ln(2)/half-life. Hence the equation can be expressed as follows: N / N = exp(-[ln(2)/half-life]*t) 0 N / N will express the amount of substance remaining as a percentage 0 of the original. Plugging in the numbers: exp(-[ln(2)/250,000y]*6y) = 99.998% Hence, ca. 0.002% (actually less than that) of the material has decayed. It may be the case that even this minute amount of "impurity" could poison something like weapons-grade material, but I am not a radioactive materials expert.

Non-US or US-exportable secure modems or RS232 crypto/authentication
by Bill Stewart 17 Dec '03

17 Dec '03

I'm looking for a source of modems that can be used in non-US sites that support built-in encryption or at least strong authentication (e.g. token cards would be great, or something stronger than simple password+dialback.) A box sitting on the RS232 side of the modem would probably work fine too, as long as it didn't interfere much with regular traffic. One of my customers would like a managed router network, but they're paranoid (probably reasonably so :-), and our router management folks insist on modem access to the router console port so they can do things like reconfigure routers or reboot them when they're hosed. The customer views dialback as cute but crackable, and would probably accept one-time passwords like S/Key but not basic reusable passwords. Thanks!
