This came up in a chat at work, and it's got me curious. I've done lossless vinyl rips to preserve stuff I can't find good digital copies of (the Loving Awareness album for example) which came out to about half a gig, but I think that's more to do with the unreasonably overkill sample rate I was using (I know better now!) rather than any meaningful way of measuring data storage because 192 kHz FLAC is going to have a far better noise floor than vinyl.

As vinyl records are fundamentally analogue we need a digital modulation technique, apparently vinyl has about 18 kHz of bandwidth available so perhaps we could employ several frequency-shift keying channels? Could we do better than audio frequency shift keying^1 since vinyl records have more bandwidth available than the phone lines this is used on?

Last summer, I read an essay^1 by Paul Graham called "The Four Quadrants of Conformism". It argued that people's personalities can be categorised on two axes, how conventional- or independent-minded a person is and how passive or aggressive this nature is. The essay also argues that the sizes of these quadrants are unequal size with there being more conventional-minded people than independent-minded people and more people are passive than aggressive in this nature.

While the implications of this are quite interesting on their own, I'd like to know if this idea can be empirically tested. Would it be possible to design a system of measurement for these traits and where a person might fall on these axis? Can we make useful predictions about people's interactions based on where their positions on the axes? What would this measurement entail, would it be based on a questionnaire like other psychological studies or something else?
