 Being truly random is hard. Computers can't be random: no matter how much they mangle and transpose numbers, if you start with the same seed and apply the same algorithms, you wind up with the same results.
Which is bad news for the crypto biz: untold millions of daily transactions rely on truly patternless random numbers for secure, encrypted connections. So where do truly random numbers come from?
The good ones come from some interesting sources: there was SGI's LavaRand, a system that used a Webcam trained on Lava Lites, its successor LavaRnd, which keeps just the Webcam, HotBits, which uses a Geiger counter and random.org, which uses 2 radios tuned to atmospheric noise. Hmmmm... I wonder if you could use some combination of blog RSS feeds to generate truly random numbers... |

Apache problems... the new HD is doing fine, but Apache isn't referring virtual domains correctly... I think it's an issue with the 10.2 upgrade which I applied to the new drive... so anneknudsen.com, ridey.net, tracksidephoto.com and ppagla.org are temporarily lost in space... (though the preceding links will work). I'm guessing we have a new version of Apache thanks to the upgrade, and something's up with the config file... Comments 9:49:39 AM
