On the one hand, everything is essentially random, but if you look at trends across, say, all stocks of a particular type (say, tech stocks), their value curves pretty much match each other. The same can be said for tracking-funds like DJIA, Nikkei, NASDAQ, etc... when one goes up they all go up. Also, barring big crashes, the trend is that all values go up (at least in numeric value) over time. Now, maybe one could take two similar (or, based upon my "complaint" above) figures and use the "noise" between the two (since their values are definitely not exactly the same, even if the curves look similar at a high-level) for your source of entropy. Of course, this is not practical: nobody is going to store historical stock data just for entropy, and nobody is going to query Google Finance every time their server needs to start. :) - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk7w7yEACgkQ9CaO5/Lv0PA0kACfXujaU7D7u5KFQd6KEOYHcTzT M6cAoKjLsqcXrqSLPUcJg8mu/eu5I5gw =2lCE -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
