Long ago there was a slashdot story about someone who returned to their office to find a co-worker looking at a long printout with a number of peaks circled on it. This printout turned out to be a frequency spectra derived from a covert recording device monitoring the 3 phase feed into the facility. This turned out to be useful for estimating Uranium enrichment yield. I thought it was a damned cool story, but now I can't find it any more. 8(

Google won't help me find this story... but it did at least once in the past. And now I can't even find that reference to the earlier reference.

Also... try finding something about marking up hypertext documents... you can't... you have to know that "annotation" works instead... at least it used to. Who knows what Google will spit out these days. Google-fu isn't what it used to be, because Google goobered it up.
