Mostly looks good. At the very end of the section on noise, redundancy and information theory I think I made a comment that the scribe missed. If there's no dissent, I'd like it recorded: After the existing entry: Chris: redundancy helps succesful conveyance of information accurately. Hence the need for surrounding context when using a URI to transfer information Noah: True, but I wanted to clarify that I wasn't referring to lossy channels or redundancy when I suggested that information theory could help us. Though I'm not expert in Info. Theory, my understanding is that it gives a definition of "pure information" (my term, not Shannon's--I don't have his writing here=) that is essentially what you are TRYING to communicate through the channel. So, by analogy, we need not have redundancy in a temperature value or the words in a poem to say that they are "information". We may need redundancy to communicate them with some predictable probability of success through a noisy channel. HTTP needs redundancy on the wire, the info resource definition as information does not involve redundancy IMO. I've elaborated a bit but I think this was the spirit of my comment. Might this be added to the official minutes?
