...Date instance has no concept of time-zone. This might seem strange if you call toString() on a java.util.Date, because the toString is relative to a time-zone.

Why are functions in Ocaml/F# not recursive by default?
...es (f1, f2 etc.) which pollutes the scope and makes it possible to accidentally invoke the wrong "version" of a function. And there is now a discrepancy between implicitly-recursive fun-bound functions and non-recursive val-bound functions.
Haskell makes it possible to infer the dependencies betwee...

Implications of foldr vs. foldl (or foldl')
...
@Desty because it produces new part of its overall result on each step -- unlike foldl, which collects its overall result and produces it only after all the work is finished and there are no more steps to perform. So e.g. foldl (flip (:)) [] [1..3] == [3,2,1], so scanl (f...
