Draw a perfect circle from user's touch
...
A classic Computer Vision technique for detecting a shape is the Hough Transform. One of the nice things about the Hough Transform is that it is very tolerant of partial data, imperfect data and noise. Using Hough for a circle:

Aren't promises just callbacks?
...s easily
Promises are chainable (monadic, if you want):
If you need to transform the value that a promise represents, you map a transform function over the promise and get back a new promise that represents the transformed result. You cannot synchronously get the value to use it somehow, but you...

What is a lambda expression in C++11?

A quite common pattern is to build monad transformers instead of simple monads (see also the link in the next paragraph). It basically means you build something that must be combined with other monads, resulting in a more complex one able to handle features of both ...
