PGP Tools for Linux
by Mark Grant 17 Dec '03

17 Dec '03

Hi, Now that I'm back in Europe I've been able to do some more work on Privtool (PGP-aware mail-reader for X11 on SunOS/Solaris, Linux and FreeBSD) and should be releasing version 0.86 once I've fixed the last segmentation fault (see my Web site for details of the latest changes). In the meantime I've finally got around to fixing one of the early PGP Tools versions that escaped to Europe so that it works on Linux (and probably FreeBSD). I'm just about to upload pgptools.linux.1.0.tar.gz to utopia.hacktic.nl and idea.sec.dsi.unimi.it, so it should be available there shortly. I'm not back on the list yet, so send any mail to this address. Mark |-----------------------------------------------------------------------| |Mark Grant M.A., U.L.C.

WHAT TOPICS ARE APPROPRIATE: "On topic" discussion includes technical aspects of cryptosystems, social repercussions of cryptosystems, and the politics of cryptography such as export controls or laws restricting cryptography. Discussions unrelated to cryptography are considered "off topic". Please try to keep your postings "on topic". In order to assure that the quality of postings to the mailing list remains high, repeated postings "off topic" may result in action being taken by the list moderators. MODERATION POLICY: In order to keep the signal to noise ratio high, the mailing list will be moderated during its initial weeks of operation.

I disagree that it's a "dangerous misconception" to believe that "LCD screens reduce the risks of emanation." While it might be correct to say that it would be dangerous to believe that they ELIMINATE the risks, LCD displays would make it exceedingly difficult to read the screen remotely. The main reason is that the LCD segments are activated in parallel, which means that the electronic noise associated with a particular row is a smeared product of each portion of the display. This is quite unlike CRT's, in which individual pixel information is completely (well, except for color) demultiplexed by time. > However, the gotcha with current laptops is their >backlighting.

DentlCare Management, Inc. (DentlCare) is a publicly listed Nevada corporation founded for the purpose of acquiring dental health care facilities nationwide. DentlCare has developed a model for the delivery of quality dental care to all segments of its population. DentlCare and subsidiaries provide innovative services and products to the dental marketplace, at affordable rates. "Given the rapid success of this concept, its no surprise that Wall Street has latched on to it. In the past year eight PPMs have gone public, raising over $350 million in new capital. Many of the stocks sell at better than 35 times earnings. Some, like Med-Partners, are closer to 70 times." Forbes Magazine, September 1995. The DentlCare model provides a fully-operational dental health care facility and all management support to the dental professional on a "turn key" basis. Because of its managerial efficiency and the volume of business created by aggressive advertising to the "fee-for-service patient" and participation in "managed care" dental plans, the model generates higher than average operating margins. DentlCare provides business and practice management services to dentists through its wholly owned subsidiaries, which currently manage twelve fully operational clinics, along with one mobile dental team. Through these contractual relationships, the Company manages the financial, administrative and marketing activities, allowing Dentists to concentrate on the delivery of high quality, affordable dental care to their patients. The success of these operations indicates that the same concepts can be duplicated in major metropolitan areas throughout the United States. The clinics are to be located in those regions of the country where the demographics support a high volume operation, mainly in large metropolitan areas or in cities where the percent of residents over age 65 exceeds 15% of the total population, or in areas which have strong Managed Care programs. The Companys target market is the estimated 60% of the American public that do not have a dentist. They will go to one only if they are in pain. As badly as they need regular dental care, they avoid it because they are afraid of pain, expense, and humiliation. The Company has so successfully addressed these three fears that 90% of the fee-for-service customer base are patients who have previously avoided regular dental care. We believe this is a timely opportunity to invest on the ground floor of a new company with explosive growth potential.

RE: Silence is not assent (re the Vulis nonsense)
by Blanc Weber 17 Dec '03

17 Dec '03

Well, I see that my email came out a bit skewed, so I'm reformatting a bit and resending to make it more readable: ----------------------------------------------- From: Dale Thorn ... I believe that my idea above [asking John Gilmore to speak up, and if he doesn't, say to the list that he has declined to do so] is still a great idea (if the subscribers are not afraid of confrontation), as it would tend to force the issue more into the open. I don't know what you mean by "forcing the issue more into the open". Do you mean the issue of John' s not replying, or of censorship per se? If you mean "forcing the issue of John not defending himself on the list", I don't see where the issue needs to be forced. John has rarely posted to the list since it started, and typically only announcements of events or crypto papers/conferences, etc.; he does not engage in the discussions at all. I personally have no argument with his decision over when he posts or what he cares to post about, or how much or how little. My own interest in the list has nothing to do with whether the list owner is moved to defend himself or not. I'm free to roam at will, read or delete, post or unsubscribe, publicly and loudly or privately & quietly. I don't feel constrained in any way, shape or form to stay or go or speak or stay quiet. I make all my own decisions about this and John never knows nor, I expect, suffers any concern over it. And vice-versa. I (and apparently many others) do not feel the need to discuss John's decisions. I, and others, are not bound, like geese flying in formation, to follow his lead, nor are we going to fall apart at a loss for direction if he fails to "show up". You mention what "others had overlooked". How about this: Tim May sent a message the other day stating (in essence) that the whole "censorship" thing was pretty much a size (rather than content) problem. I posted that notion twice, and there has been *no* discussion of it, as far as I know. Too bad Tim didn't post that at the beginning of the affair, since everyone apparently reads *his* mail. What I meant by what "others had overlooked" was in regard of the content of posted messages which I have read, not in regard of *which* poster's messages are overlooked/not read by others. Tim can have whatever opinion he likes about censorship or size or content, and none of us are under any obligation to either agree or disagree with him. On a libertarian/anarcho-capitalistic list like this, the individuals who have elected to join and lurk or post are not expected to do anything but follow their interest. There are more than 1200 subscribers to the list; if each and everyone of them had decided they had something to say to each other about the concept of the rights of the person whose computer these messages are all flowing through, that would have been their fortunate privilege to do, as no one has put any limit to the number of messages allowed, from any one, during any particular period of time. (Of course they would all be expecting not only that their particular message would be read, but that everyone would absorb their wisdom, right. Not!) >Frankly, most of the long-time members of the list >would not need any such statements of defense from >John in order to appreciate the nature of the >circumstance and the reasoning for his symbolic >'censorship'. I apologize in advance for this one, but I honestly think that statement says more about acceptance of the Iron Boot principle than it says about what really happened. I for one am not an insider in any of the various cliques that surround this list, so perhaps I missed something that would explain it better to me. I suppose you are referring to an unspoken understanding, but again, and for future reference, you might want to consider the non-long-time members and speak the unspoken, as it were. What really happened is that, upon weighing the relative merits of John's action vs Vulis' contributions, what John did was seen as more of a benefit than a detriment, and this dimmed any arguments which might have been raised against it. It's not like everyone was clammoring for the privilege of reading what Vulis had to say or there aren't any other avenues to getting his literary works. The "unspoken" understanding on the list is that it was started by a couple of guys who happen to be very libertarian/cryptoanarchist in their philosophy of life (not simply as it applies to cryptography, but rather as cryptography relates to that philosophy). I put "unspoken" in quotes because there have been no end of discussion and comments and replies and retorts and flames on this very subject in the past years since I've been on the list (Oct '93, and it is actually what attracted me to subscribing), so it has hardly gone unmentioned and to many is no surprise, although is often difficult for them to see or agree with. I recommend that you go through the archives and do a little light reading. Your mind will soon be saturated with the flavor of the underlying theme, and you will Understand. .. Blanc

I will pull it out of a larger volume when I have time. > When I was doing my undergraduate work several of us built a heat-seeking and homing circuit which we subsequently tested in a small (24-inch) solid propellent rocket. Four CO-2 cooled germanium sensors picked up radiation from a small flat-topped piramidal mirror which drove fin servos to 'null' onto (place its image atop the piramid) the heat source. One evening we were able to 'shoot down' a lit cigarette tied to fence up in the hills near the college from a distance of about 1/4-mile. For some time we considered making available 'Visible Missile" plans/kits, for a few hundred dollars, which had everything except the easily obtained zinc-sulphur propellent (would this be illegal given the laws passed since the '70s?) so those interested in IR missile technology could learn from a functioning testbed. I did quite a bit of serious amateur rocketry in my teen years through the Northrup Rocketry Club (So. Cal) and launches at a site near Edwards AFB (they were happy to track our launches and make sure there was no aircraft hazzard). Our 24-inch rockets reached speeds of over 1000 mph in about 1 second and altitudes of about 10,000 ft. 48-inch rockets (still small enough for shoulder launch) could reach over Mach 2 and altitude/ranges of about 50,000 ft (all figures insignificant payloads). I'm certain I and many of my friends got much of our interest for math and science and subsequent academic success from such hands-on activities which were encouraged or supported by teachers, parents, corporations and the government. We were forced to solve real chemistry, math, engineering, physics and material science problems. This has all vanished is our zeal to protect youth and society from any activity which might lead injury or misuse. I can't even find a place to buy a niece a real chemistry set as tort laws have forced them from the market. When considering the plumeting interest and achievement of our youth in math and science we look nor further for a reason. -- Steve

Encryption/data-changing in russia
by Benjamin Grosman 17 Dec '03

17 Dec '03

Dear All, whilst on the subject of PGP in Russia, I encountered something very interesting. A friend of mine who is Russian, but lives out here, frequently corresponds with friends in Russia via email, and in the course of sending emai, they occasionally send an attachment. However, the attachment that _all_ his russian friends send, including the ones who use MIME capable email clients such as Eudora, always, _always_, uuencode files, and they say they can't do MIME. I am wondering if the encryption/data-changing laws in Russia are so strict as to disallow MIME encoding even, but still allows UU for some reason? Any clues as to this? Yours Sincerely, Benjamin Grosman
