    Perhaps mistercow means things like def foo(): x = 5 def bar(): print x def baz(): x = 6 print x bar() baz() print x Which prints 5, 6, 5. If baz tried to print x before assigning,…

    Not really -- "any" and "filter" are total functions, but "first" of an empty list is undefined. On the other hand, that also applies to foldl1 and {max,min}imum{,By}, so it's prob…

    You should add the word "web" to the title. There are many other kinds of caching.

    That's a fixed-point combinator, but it's not actually the Y combinator; in fact, it defeats much of the purpose of Y, since it's defined using explicit recursion, which Y is desig…

    "bar none" is a little excessive -- Haskell's syntax is probably even cleaner. Compare: 1. map (*2) [1..10] 2. sum [1..1000] -- sum = foldl (+) 0 3. any (`isInfixOf` tweet) wordlis…

    No, because robbing someone of their incentive to work is a net loss to society, so the bandits would no longer be perfect (unless they in turn gain a corresponding incentive to wo…

    This title is designed to get people to click it (to discover what "The One Group" is), rather than to be informative. Please add e.g. ": Developers" to the end of it, so that peop…

    The difference is that the whole point of the Y combinator is that it's a fixed-point combinator that doesn't use explicit recursion. Imagine that you didn't have "var", and couldn…

    Here is Richard Feynman's answer to a similar question (this isn't about gravity but about this type of question): http://www.youtube.com/watch?v=wMFPe-DwULM

    Some methods: 1. Change your layout from "USA" to "USA International (AltGr dead keys)". Then use right-alt+key to make various special characters (you can look at what each charac…
