So the results are in, and I haven't actually noticed much of a change. Last night I went to sleep after 11 and woke up at 5:30. So apparently night shift by itself doesn't have much of an impact one way or the other, at least n

Parts of it once were, yes.

Night shift seems to have a very strong causal effect on my sleep cycles. Up until about ten years ago I was a night owl, rarely falling asleep before midnight and rarely waking up before 8. Then I started getting serious about light hygi

Planck units are physical limits. The Planck mass is the limit of the mass of an elementary particle before it would form a black hole.

I have to confess I have not actually done the math.

Maybe. It's not clear whether these are fundamental limits or merely technological ones. Reversible (i.e. infinitely efficient) computing is theoretically possible.

This was my thought. Nanoseconds are an eternity. You want to be using Planck units for your worst-case analysis.

This analysis is not quite fair. It takes into account locality (i.e. the speed of light) when designing UUID schemes but not when computing the odds of a collision. Collisions only matter if the colliding UUIDs actually come into causal

Um, where is the car? All the images are of (parts of) the interior, and the captioning is bizarre. Ooohh! It has a steering wheel! (And it's a input! Who knew?)

Singapore is on the equator, so winter is not even a well-defined concept there.

OK, so the defining characteristic of a monad M is that: a.M(b).M(c) = a.M(function(x){return b(x).M(c)}) So the next question is: why should I care about that pattern in particular?

I can do you one better and specify that the normal base-2 integer represented by the bits is the number of up-arrows. But as /u/tromp has already pointed out, that is not very interesting.

Ah. Thanks.

Thanks!

I had the privilege of working with Don back at JPL at the time he invented the rocker bogey. (I wrote the software for the first prototype with a computer on board.) Not only was he brilliant, he was also a really nice guy. I didn'
