http://www.thestranger.com/2002-07-04/city4.html "We have always lived in slums and holes in the wall. We will know how to accommodate ourselves for a time. For you must not forget, we can also build. It is we who built those palaces and cities here in Spain and America and everywhere. We, the workers, can build others to take their place. And better ones. We are not in the least afraid of ruins. WE are going to inherit the earth. There is not the slightest doubt about that. The bourgeoisie might blast and ruin its own world before it leaves the stage of history. We carry a new world, here in our hearts. That world is growing this minute." Buenaventura Durruti:

For example, a single past world line for me, for you, for Hal, for Chaucer, for Einstein. Now we may not know what this world line is very accurately, but as we look at more closely, e.g., by examining the photographs someone may have taken, or their diaries, or whatever, the more we home in on what that world line was. We never look closely and see two or three or N different histories, we just see a higher fidelity view of what we must assume is the One True Past. I don't doubt that Hal gets the sense that many potential Hals could have resulted in the current Hal...an interesting notion. But everything does in fact point to a One True Past which various measurements get closer and closer to, and which no measurements contradict. This is what I meant by "convergence." Homing in, getting closer, sharpening the image, filling in the details. As for "tacitly assuming some kind of communication between observers," I am _explicitly_ saying that observers get together and compare notes...and they find no contradictions, if they are honest observers. Hal may have meant something different, perhaps. --Tim May --Tim May (.sig for Everything list background) Corralitos, CA. Born in 1951. Retired from Intel in 1986.

Take several encryption algorithms of your choice, then use a fixed IV, and the same sets of keys, and encrypt blocks of 0's. For each algorithm, compute several sets of staticstics (a la NIST or DIEHARD). With 100 blocks of 10 Megabytes (100 different keys) you should see some interesting differences. Remember, your question originally was "how can you tell which algorithm", not "how do you find the key". Let us know what you find out :-) --yes :) Patience, persistence, truth, Dr. mike __________________________________________________ Do You Yahoo!? Yahoo!
