I'm not sure what a "79% correlation" even means. The way to describe correlations is to provide estimated correlation coefficients. It appears that even the original article uses this bizarre percentage notation ("r = 63.5%"), which suggests that perhaps the authors don't understand correlation as well as they think they do. Sigh. This is what happens when computer scientists try statistics without any training...

What Electronic Door Lock Would You Buy? 97

zentigger asks: "I work for an ISP that supports internet in several dozen remote areas. Our POPs are typically fairly small shed-like structures, with a couple racks of equipment. For the most part, we can manage this stuff in-band, but frequently we need to have a local agent physically access the equipment for some minor maintenance work or adjustments. As time goes on, the shuffle of keys is becoming farcical and expensive. What we need is an electronic lock of some sort that can be reprogrammed remotely (preferably from a remote console via serial or directly via ethernet) that will stand up to extreme weather. Google certainly turns up lots of glossy brochures — although I don't see how they can -all- be 'The heaviest duty lock you can buy!' Does anyone have good experiences with any particular products or perhaps other means of dealing with the key shuffle?"
