When I went to grad school, my career had been programming, and I'd done a lot of it for some years. Two applied math profs were starting a computer science course and asked me what good lessons I'd learned, and I answered. The

I tried a co-founder. He had a lot to offer. But too soon he wanted to do no work and be a bitch on the team. So, I had to break off with him. "Co-founder disputes"? Yup, they are likely. The result is, I've just had

But, could molten aluminum or other metal be used for energy storage? So, when the sun is shining and/or the wind is blowing, use the resulting electric power to heat the metal by, say, just simple resistance heating. Then when want t

Maybe they are just giving back the energy to the grid in two respects, (1) energy they contracted for today they do not consume but sell back to the grid and (2) the energy was to come via the grid to them but, in not consuming that ener

Thanks for the info on the $1.60. I don't yet know the details of how Web sites get paid for running ads. Of course, at venture firm KPCB, the Mary Meeker reports commonly claim that a Web site can get paid $2 per 1000 ads displayed --

Good lecture: Important content, well organized, clear. But, but, but: It looks like there is a kind of a bus or bandwagon , and after this lecture I'm thinking of either not getting on or just jumping off before going too far. Su

Okay, if the title is correct, then to heck with traditional RAM and, instead, have very long addresses , say, a(i).b(j).c(k) ... stored in, say, a key-value store. Then, as usual for caching, just hash that long address. Why do

A mechanical engineer knows about the properties of the metals, plastics, etc. he uses. A civil engineer knows about strengths of steel I-beams, etc. An electrical engineer knows about capacities of cables, switches, etc. So, these engin

Yes, long ago it was observed that the first step in proving software correct was a clear specification of what the software was supposed to do and that for a lot of realistic software writing that spec was unreasonably difficult.

Fine, but the Fourier part is really in the violin and not in the human. Listening for beats is very old stuff in signals, and no doubt circuits and/or software are sometimes used to detect them; if so, then we can do the stuff with th

Let's see: (1) Make some progress learning to play violin. I did. E.g., I made it through not all of but over half of the Bach "Chaconne", regarded as great music and challenging by nearly all violinists. (2) Learn some F

In the violin tuning, a human just listens to the beats. In principle, a tone deaf person could do that. So, the beats just need sensitivity to volume, amplitude modulation, not really frequency. So, the frequency stuff is in the violin,

The sound from one string on a violin is essentially periodic. So, can apply Fourier series. When do that, get the amplitudes of the overtones. The periodic sound from a violin string is not a sine or cosine wave, but, as in Fourier theory

How about an 18th century machine that performs Fourier analysis? A violin! Also it has a really good numerical approximation of 2^(7/12). Why? A violin has 4 strings. The lowest string in frequency is the G, the first G below middl

Somehow much of the image I had of Ballmer was that he was shouting, throwing chairs, a buffoon, not very thoughtful, and standing on the good thinking of Gates and the rest at Microsoft. In this lecture, he did some buffoon-like shouting b
