10:08 pm - Interesting notes
An interesting bunch of information about how various famous and prolific geeks organize their lives. I may have to take a few tips from this. Maybe use my blog here more for thoughts on projects and things.
Here's a link to it on my own server in case it disappears from the other one.
On that note, I had an interesting idea today. Noise cancelling microphones are neat, but one difficulty is deciding exactly what's noise, and what's something you want to keep. I'm not sure how current noise cancelling microphones do this, but I thought of a way to do it. This may even be how humans manage to listen to just one person talking in a noisy environment filled with people talking...
You have two or three microphones, and you make some decision about some component of your signal that isn't noise. Then you measure the timing differences between that signal showing up at the different microphones. That gives you a spatial location. So you can look for other signals who's timing indicates that they come from a spatial location very nearby the one the signal you know you're interest in comes from. You can tell this by similar timing patterns. With good, sensitive electronics for detecting the timing differences, the different microphones don't have to be that far away from eachother.
