The fact that this patent was issued indicates to me that the patent office does not understand computer technology. There is nothing new here that I was not using for other purposes at least 20 years ago. Unfortunately, once a patent is issued, it cost a great deal of money to break.

I want to apologize to everyone for being gratuitously nasty here. It wasn't called for. >> Thats funny. I thought you were being completely serious and I sent you this file. You are exactly right. it is of GREAT use for doing wordlist crack runs. Why dont ya check out some realllyyy secure systems and find out what utils they use to test their own security. I ALWAYS use created segments of this when trying to brute force my way into my OWN machine. It helps finding bugs that overwrite the stack..etc. But... apology accepted. You may learn from it.

-----BEGIN PGP SIGNED MESSAGE----- Here's an idea that I always wanted to implement but never did yet. I thought I'd share and if someone else has already done it let me have a copy. I should be able to execute scripts remotely by sending e-mail to an account. Simple mail-handling scripts at that account should check the PGP signature (and timestamp/counter to prevent replay/delay attacks) and then pass the contents to a full script-language interpreter. Perl is a natural choice of interpreter. Has anybody implemented this (hopefully complete with replay/delay prevention)? Thanks! Bryce P.S. No, actually I can't think of any good use for this trick. But maybe if I had it I would find good uses for it. -----BEGIN PGP SIGNATURE----- Version: 2.6.2i Comment: Auto-signed under Unix with 'BAP' Easy-PGP v1.1b2 iQB1AwUBMd7FIEjbHy8sKZitAQHhRQMAmZoekRgmUKSYv89/QrkzRFdTUZLZHK8a tlaXLtyJXrOjajxJRVvXWY7Rum6mVXe/4eHTPCGzzWQdXMJB/TJSQeRmTuSiSd9i 0DtWcQSmP4q5AFor48NtNvqAOEonf5Vi =My90 -----END PGP SIGNATURE-----

[RANT] Giving Mind Control Drugs to Children

They have to scan through it all day long and look what kind of >self-righous pricks they have become! The doublethink and hypocrisy of modern society is astounding. A friend of mine has an 8-year-old son, whom he has custody of on weekends. Sometimes his son wants to have his friend stay over Saturday, as kids like to do. When the mother (a single mother, as this is California) drops her son off with my friend (also single, of course), she includes several "Ritalin" capsules with instructions on how to dose her son with this depressant/behavior modification drug. My friend ignores these Ritalins, which upsets the Mom greatly the next day when she realizes her son has not been given the tranks that are also known as "Mother's little helpers." I've been over visiting my friend to see some of this. The Ritalin-sodden kid arrives like a zombie. When the Ritalin wears off, he's rambunctuous, but all kids are. My friend Paul has had to discipline him a bit to keep him from--as the psychobabbles would say--"acting out." This discipline sets him straight, but it's not something his New Age "supermom" would ever think of doing. Hence the kid throws temper tantrums, acts out, calls her "You fucking asshole" (remember, he's only 8 or so), and so on. So she cranks up his dose of Ritalin and he's zoned out for a while. Frankly, I think telling the kid that if throws a tantrum he'll get punished for it is a whole lot more normal--ever notice that a dog smacks her puppies when they get out of line, or that a cat swats her kittens the same way? It establishes the rules of the game. (No, I'm not talking about "child abuse," the sadistic beltings and lashings which some parents give. However, here in Kalifornia it is essentially illegal for parents to use corporal punishment. Heavy doses of drugs are, after all, the California way!) "Just say no to drugs!" is the mantra of these doublethinkers, as they dose their kids at school and at home with tranquilizers and behavior modification drugs. The kids grow up thinking pills are the answer to everything. Also in California, the public schools dispense these mind control drugs to a growing fraction of the school population. Apparently this has become the largest part of the job of "school nurses." I believe parents are involved in this dosing regimen, but I would not be surprised if this changes. After all, such medical procedures as abortion are now handled "discreetly" by the school nurses, without any requirement that the parent be notified. Whatever one thinks of abortion, this is surely a strange state of affairs, where the public school system is taking on such a role and is actively deceiving a parent. The connection with the themes of our list is that this linguistic doublethink is what allows Big Brother's control of our communications and private files to be called by the relatively benign name of "escrow." --Tim Boycott "Big Brother Inside" software!

It seems that these companies are going to have a problem as long as they use lists of *excluded* sites. Forget insight into company policy; these are global indices of "smut" on the net. (The lists of the more liberal companies are probably most attractive to those not titillated by NOW position papers.) They have to give you the list, and they have to give you software that uses it, so there's no way to achieve complete secrecy. I think the best they can do is to distribute a list of hashed URLs. -- Eli Brandt eli+(a)cs.cmu.edu

See page bottom of page 561 in Knuth's "Searching and Sorting", First Edition. (Vol 3 of Art of Computer Programming) With a Bloom filter you can hide which URLs you reject yet quickly rejecting particular URLs. Compute SHA(URL) yielding 160 bits. Divide that into 16 ten bit quantities b[i], for 0<=i< 10. Reject the access if P[b[i]] = 1 for each i. P is an array of 1024 bits computed by someone with the index prohibitorum. (pardon my Latin) Yes, this excludes 1/1024 "falsely accused" URLs, but you get the idea.

As has been discussed in numberous previous threads on this topic, even a passive rating system is very hard to implement. The computer doesn't know if you hit delete because the post was garbage or because you are running late on some project. An active rating system is virtually impossible to implement, given the added workload on the readers. Good lucky anyway, -- Lucky Green <mailto:shamrock@netcom.com> PGP encrypted mail preferred.
