Thinking that LCD screens reduce the risks of emanation monitoring is a dangerous misconception (at least under a high threat model). LCDs' current requirements are pretty small, and they only emanate a low magentic and electrical field. However, the gotcha with current laptops is their backlighting. Electric and magnetic fields are considerably higher compared with a low-res/contrast device. There are documents that circulate within certain security circles that list just how noisy (and therefore easy to monitor) various off-the-shelf machines are. It would be an interesting project for some ham radio type Cypherpunks to measure their machines, and publish the results. Or, for some well connected person just to scan and anonymously post such a document to the list. Of course, I'd never encourage anyone to do something illegal. Joel

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

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 to 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

_______________________________________________________________________________ From: Nelson Minar on Thu, Dec 5, 1996 19:00 >Ah, the age-old question. This is the same question as "is there a way >for me to show a web page to someone and not let them copy it?", As a sidelight to this thread which has already strewn far from the [crypto] heading, it *is* possible to show a web page to someone w/out letting them copy it. Some guy in California, who touts the fact he has "every foul word known to man" on his site (to generate more hits) has (I believe developed/worked to help develop) a product which does so. I don't know how he does it, and I know there are ways around it through sniffing, etc., but when you do the trivial act of "View Source" in Netscape, a filtered version is displayed in the source window. While it's really not possible (AFAIK) to eliminate unwanted copying by a person who knows what they're doing, this works against people who don't (like most people). If anyone's interested, I *might* be able to find the URL somewhere. PM
