If you find this sort of thinking interesting, definitely also check out "The Psychology of Invention in the Mathematical Field" by Jacques Hadamard.

I've been trying to find a Kubrick/2001 anecdote I vaguely remember, maybe somebody here has a source? Roughly a lighting technician found the initial very bright point-source lights needed to illuminate the space ship models wer

I am assuming shards are much smaller than 1/3rd of all the data.

There never is a break-in where they get 1/3 or 1/2 of the accounts. It has to be nearly all or some much smaller faction. (my own presumption based on the idea nothing large does mere 2 to 3 way replication or partition)

Speed differences of that magnitude are largely due to bad interactions with R's data allocation model. R for loops are not that slow if there is no allocation going on, and there are ways to organize the allocation ahead of time: h

Actually it sounds like they broke their own rules which seem to not allow removal of passengers for crew (but do allow it for overbooking, which is a different situation): http://www.nakedcapitalism.com/2017/04/un

Probably isn'y the sky falling. But if knowing the length fixed all hash function issues then cryptographic hashes would just use a some more bits for length.

Dual numbers are a blast, especially with type-templated languages. I wrote a Scala implementation some time ago that I would like to share: http://www.win-vector.com/blog/2010/06/automatic-differentia...

I think the intuition that such infinite games make sense requires the axiom of determinacy to be well founded. The axiom of determinacy has been known to contradict the axiom of choice since the early 1960s (i.e. it is inconsistent to have

Jacques Hadamard's "The Psychology of Invention in the Mathematical Field" 1945 is a very good essay on the deep preparation, rest, and then inspiration pattern (and possibly how to cultivate it).
