Vim: Creating parent directories on save
...ries for files like ftp://* and !isdirectory will prevent expensive mkdir call.

When NOT to use yield (return) [duplicate]
...is h deep. Then there will at most points be O(h) nested iterators built. Calling "MoveNext" on the outer iterator will then make O(h) nested calls to MoveNext. Since it does this O(n) times for a tree with n items, that makes the algorithm O(hn). And since the height of a binary tree is lg n <=...
