#12I like his speaking style and appreciate the intro to Kademlia and Chord. This page has some visual representations: http://tutorials.jenkov.com/p2p/peer-routing-table.html

#13"In the middle of the pattern matching algorithm, there was this single comment that read # and now for the tricky bit." (~10:40) At ~28:00 is he saying that the optimal computing device could operate 27 orders of magnitude more efficiently that what we use today? At ~36:00, finally something to make me sit up. "content addressable store".
Thermodynamically speaking, a perfectly reversible computer which erases no bits (and creates no entropy) approaches zero watts per operation to run.
Kurzweil has pointed out that one can think of the 10^15 state changes per second going on inside a 1Kg rock with no outside energy input as a computation device.
Ok, so at 28 minutes, he's referring to some quantum mechanical lower bound to change a bit. I imagine the rock is using that really tiny amount of energy from the outside environment.

#14During the last minute of the talk, he says:
"Computers are becoming a big environmental threat. They're using more energy than air traffic."
Is this actually true? Sure, the average person spends a lot more time on a computer than in a plane, but still it seems crazy that they'd be comparable. Or at least the comparison isn't very relevant, because the Internet can significantly reduce people's need to travel.

Well modern aircraft are pretty efficient and probably not the top offender.
However he also mentions we probably can't do a lot more with computer to reduce their power consumption.

You are getting downvotes, but energy efficient computation has been a large driver in the recent upsurge in interest in C++.

#18What is this about? Edit: Strange Loop is a multi-disciplinary conference that aims to bring together the developers and thinkers building tomorrow's technology in fields such as emerging languages, alternative databases, concurrency, distributed systems, mobile development, and the web. Strange Loop was created in 2009 by software developer Alex Miller and is now run by a team of St. Louis-based friends and develope…

Wait C++ is has been getting more popular? I'm not complaining (I mostly like C++), I guess I just didn't get the memo.

#20Great talk. Very light-hearted and entertaining. Always impressed by Joe. Programming since the 60s and still programming, still writing, giving talks. He is a great role model. I wish I would be programming and be just as excited about it when I am at his age.
I wished I would be half that excited about it at my present age!
