I remember inspecting the thermostat in my parent’s house as a child. It was a coil of something metalic which I assume expands and contracts with temperature and physically pushes electrical contacts together to turn on the heat when needed. Knowing how it works, it’s hard for me to imagine that this feels like anything. The whole contraption is just an arrangement of molecules doing what molecules do. But then again, so am I.
This is great. Suggest one additional bit to show black at the bottom. That way the player of black is not handicapped by playing from an upside down position.
Or just rip off the chess piece design of this other minimalist chess board simulator, which is never upside down:
Note: I was carefully reading along and well into the third notebook before I realized that the code sections marked "TODO" were actual exercises for the reader to implement! (And the tests which follow are for the reader to check their work.)
This is a clever approach. It just wasn't obvious to me from the outset.
(I thought the TODOs were just some fiddly details you didn't want distracting readers from the big picture. But in fact, those are the important parts.)
Karpathy ends on a note of despair "Maybe I should just do a startup. I have a really cool idea for a mobile local social iPhone app." That's exactly the path his now-boss took to bring us this. :)
I'll expand for those asking. The first third of the presentation does such an excellent job of steel-manning the case for concern, that I couldn't wait to hear his arguments against it. When he gets around to that, he reaches for a made-up concept he calls the "outside view" where he argues you should ignore rational arguments (aka the "inside view") if the person making those rational arguments seems weird.* Slides follow showing VCs in bad PR photos. What more evidence does anyone need?
*"But the outside view tells you something different. ... Even though their arguments are irrefutable, everything in your experience tells you you're dealing with a cult. Of course, they have a brilliant argument for why you should ignore those instincts, but that's the inside view talking."
Let me save you 20 minutes of your life: This guy's lead argument is that the smart people who advise caution in creating super-intelligence look weird. He's quite proud of this argument.
You would have an immediate market for them since dollars are the only legal way to pay your taxes. Since everyone must do this, it creates a kind of Schelling point such that everyone defaults to using dollars for everything else also.
If you produce something of value in return for Bitcoin, you must still acquire dollars to pay your taxes. If you refuse, men with guns will escort you to jail. That is what ultimately backs Buffet’s preferred currency.
FWIW, I once explained cookies this way to my non-technical co-founder of that day. I could see the clouds part and he confessed it removed all the magic and mysticism surrounding these web cookie things. It was like “ah, just small text files. Got it.”
