Garen means cook, bald means soon, I guess a pressure cooker cooks your food quickly (soon)?

If you like this, there’s a great early iPhone game called Eliss with similar finger twisting multitouch. There’s an Android version now too.

Are the exercises that go with the lectures available? Thank you!

Thank you for the link. That article says the cpu has a 630 op reorder buffer. Does that mean it has to throw out up to 630 instructions on a mispredict? That sounds huge, so I wonder if I’m misunderstanding.

"It fails for x-y when x and y are close"

I don't think that's quite right. Each individual operation is accurate within epsilon, the trouble with cancellation is that the error from operations prior to the subtraction is much larger than the result of the subtraction.

Example, if I do 1 + 2^30 - 2^30 in single precision I get zero. But each individual operation is correct. 1 + 2^30 = 2^30, so the error is 1 < 2^30 * epsilon. Then 2^30 - 2^30 = 0, which is exactly correct.

OP said:

"Shrink" is of course accounted for in the economics, but not worker and customer safety, which is externalized as violence and loss in the communities.

So they're saying that the business does pay the cost of stolen items ("shrink") but not the cost of the violence, which is borne by its victims.
