2. RX
Rx is a library for composing asynchronous and event-based
programs using observable collections.
Rx has a strong theoretical basis by using the duality between the
classic Iterator and Observer design patterns to simplify controlling
asynchrony

5. Genesis 2
AMQP (and it’s brokers
RabbitMQ etc)

6. Genesis 2
AMQP

7. genesis III

8. What we want?
We want something Generic

9. Problem

10. CUGLY
CUGLY = FUGLY but for Callbacks

11. LINQ
Microsoft
Functional Programming (posta)

12. LINQ III

13. LINQ II
var query = yourData
.GroupBy(x => x.Name,
(k, g) => g.Aggregate((a, x)
=> (x.Priority > a.Priority) ? x : a));

14. select es fmap (list map)
SelectMany (mapcat) listmap

15. DEMO

16. Implementation

19. In other words, x >>= k is a computation
which runs x, and then uses the result(s)
of x to decide what computation to run
second, using the output of the second
computation as the result of the entire
computation.

20. [ EVENT(KEY) -> (KEY ->
EVENT(MOUSE) ] -> EVENT(MOUSE)

21. In the process we've discovered what Rx really is: a fancy way of writing event handlers,
specifically event handlers that fire events that trigger other event handlers that fire events, and so on in big
chain that looks like a query

22. Async everywhere
