What are the differences between SML and OCaml? [closed]
...a top-level primitive in SML; it's not part of the Caml library. The Caml string library doesn't provide a fold function (at least not as of version 3.08). Implementations of many of the Caml List functions are unsafe for very long lists; they blow the stack.
The type systems are subtly different:...
Flatten an irregular list of lists
... if isinstance(el, collections.Iterable) and not isinstance(el, basestring):
for sub in flatten(el):
yield sub
else:
yield el
I used the Iterable ABC added in 2.6.
Python 3
In Python 3, the basestring is no more, but you can use a tuple of s...
Programmatically change UITextField Keyboard type
...rrently-focused field to update the keyboard type immediately, there's one extra step:
// textField is set to a UIKeyboardType other than UIKeyboardTypeEmailAddress
[textField setKeyboardType:UIKeyboardTypeEmailAddress];
[textField reloadInputViews];

String.equals versus == [duplicate]
This code separates a string into tokens and stores them in an array of strings, and then compares a variable with the first home ... why isn't it working?

What are the underlying data structures used for Redis?
...u asked, here is the underlying implementation of every Redis data type.
Strings are implemented using a C dynamic string library so that we don't pay (asymptotically speaking) for allocations in append operations. This way we have O(N) appends, for instance, instead of having quadratic behavior.
