Existential Pontification and Generalized Abstract Digressions

Move aside, poker! While the probabilities of various poker hands are well understood and tabulated, the Chinese game of chance Mahjong [1] enjoys a far more intricate structure of expected values and probabilities. [2] This is largely due in part to the much larger variety of tiles available (136 tiles, as opposed to the standard […]

Dumpling Hylomorphism Anamorphism: the building up of a structure. Catamorphism: the consumption of a structure. Hylomorphism: both an anamorphism and a catamorphism. This event? A hylomorphism on […]

Having worked in the trenches, Byron had some very hilarious (and interesting) quips about device driver development. After all, when a device driver crashes, it's not the […]

...because I don’t live in a room numbered 245s anymore. Yep. :-) This is a cow. They munch grass next to the River Cam. Pop quiz. What do matrix-chain multiplication, longest common subsequence, construction of optimal binary search trees, bitonic euclidean traveling-salesman, edit distance and the Viterbi algorithm have in common?

Unattributed to protect the innocent. (But you can probably guess.) “And so these poor programmers, they had to drink this much whiskey to get the job done.” [triumphantly produces a bottle of whiskey and places it on the table.] “And this group of programmers did X, and how hard was that? Two bottles of whiskey.” […]
