Maybe as a Functor
The idea of transforming one type to another one such that operations on the old type can also be transformed to work on the new type is the concept behind the Haskell type class called Functor, which Maybe a has a useful instance of.

Using margin:auto to vertically-align a div
...
In the >= IE9 age, position: absolute; top: 50%; transform: translateY(-50%); is also feasible and quite popular... (unlike top:50%;margin: - $halfHeight you don't have to know the height in advance...)

CGContextDrawImage draws image upside down when passed UIImage.CGImage
... 'flipped vertical' version of all my images. Now I don't need to use any Transforms. Hopefully this won't cause further problems down the track.
Does anyone know why
CGContextDrawImage would be drawing my
image upside down? I am loading an

Using python map and other functional tools
...ramming is about creating side-effect-free code.
map is a functional list transformation abstraction. You use it to take a sequence of something and turn it into a sequence of something else.
You are trying to use it as an iterator. Don't do that. :)
Here is an example of how you might use map...
Get nested JSON object with GSON using retrofit
...ouple of days ago. I've solve this using response wrapper class and RxJava transformer, which I think is quite flexiable solution:
Wrapper:

Serializing object that contains cyclic object value
... and also de- and encodes them: https://gist.github.com/Hoff97/9842228
To transform just use JSONE.stringify/JSONE.parse.
It also de- and encodes functions. If you want to disable this just remove lines 32-48 and 61-85.
var strg = JSONE.stringify(cyclicObject);
var cycObject = JSONE.parse(strg);

With a LocalDate in hand, we next need to transform that into a pair of moment, the start and stop of the day. Do not assume the day starts at 00:00:00 time-of-day. Because of anomalies such as Daylight Saving Time (DST), the day may start at another time such as 01:...
