Responding to msg by Stephen D. Williams: >There are some theories that various 'power' segments >of society actively cultivate a particular working >model for their own benefit. Foremost, of course, are >Clergy, lawyers, and gov. Well, reading books like the one from which I took that quote would alert one's attention to the fact that there are many working models of human nature possible, and that one should not merely take the one given out in school or at church or by whomever. I think that when one realizes that these models are all the product of our own human reasoning, then the idea of liberty & freedom becomes more meaningful, as one realizes that there are choices beyond the views created by one's elders or leaders. >I've always thought and recently espoused that there >should be classes from the beginning of highschool on >philosophy and sociology. I suppose the problem would >be which philosophy and whose spin on things the >schools would encourage. I think this would start a big fight in the public schools as to which philosophy or sociological works to use in the classroom. However, in classrooms per se if there were a general presentation of the concepts and discussions on the human ability to develop comprehensive views of the world, then everyone was turned loose in the library, each person could begin their study of any of them and proceed at their own pace & interest. At the very least they could become aware of the source of the images of human nature which surround us and could better evaluate what it means to live & act within any particular system of operations. >I just think that too many people don't think of >themselves on the 'meta' level. (Thinking about what >they think and do and why.) The opportunities for this kind of thinking are greatly limited to what the church and politics provide as a frame of reference (not that the libraries aren't open and available for budding curiosities). It was from browsing through picture books of other peoples & reading about how other cultures arrange their existence, that I developed the comprehension that there are different methods of doing things in the world, that there is such a thing as choice, and that not only cultures but individuals can arrange their affairs according to their own ideas of success.

Encrypted databases
by Ben.Goren＠asu.edu 17 Dec '03

17 Dec '03

In _Applied Cryptography,_ Bruce Schneier describes a method of encrypting a database in such a way that it's easy to get individual entries but "impossible" to get the whole database. Basically, the first field is a hash of the individual's last name, the second is encrypted (symmentrical algorithm) w/ that name and contains the rest of the info. Are there any readily available implementations of this or anything equivalent? I've a use for such, but I'm not likely to have the time to start writing anything like that for a month or two.

Remailer reorder and delay
by ghio＠cmu.edu 17 Dec '03

17 Dec '03

I added a reorder and delay feature to my remailer <ghio(a)kaiwan.com> Here's how to use it. Add a header Latent-Time: with the time (in HH:MM:SS format). You must 24 hour time, no AM/PM accepted. The seconds are optional and may be omitted. Example: > To: ghio(a)kaiwan.com > Subject: Anonymous Mail > From: punk(a)crypto.com > > :: > Anon-To: cypherpunks(a)toad.com > Latent-Time: 00:00:00 > > This message will be sent to cypherpunks at midnite pacific daylight time. You can also have it delayed a certain amount of time. To do this, put a plus before the time. Example: > To: ghio(a)kaiwan.com > Subject: Anonymous Mail > From: me(a)my.domain.com > > :: > Anon-To: recipient@site > Latent-Time: +01:30 > > This message will be delivered one hour and thirty minutes after it is > received by ghio(a)kaiwan.com. Random reordering is possible by adding r to the time. > To: ghio(a)kaiwan.com > Subject: Hello tentacle > From: detweiler(a)tmp.com > > :: > Anon-To: medusa(a)pseudospoof.com > Latent-Time: 18:00:00r > > This message will be delivered at random, but no later than 6 PM pacific > standard time. > To: ghio(a)kaiwan.com > Subject: Exterminate PGP > From: sternlight(a)netcom.com > > :: > Anon-To: alt.security.pgp(a)nic.funet.fi > Latent-Time: +04:00:00r > > This meaningless drivel will be delivered at random, sometime within the > next four hours. The longest delay time possible is 24 hours. Don't expect on the minute delivery - there are many things beyond my control which can delay mail. "Anon-To" and "Latent-Time" do not need to go in the body of the message; they may be placed in the headers if your mailer supports it. Let me know if you have any questions or problems.

Then they came for the trade unionists, and I didn't speak up Actually I didn't have a written reference, so I really _did_ forget the first line.
