Most general purpose operating systems provide interrupt facilities, sometimes called signals. 
Unhandled signals generally terminate a program in a disorderly manner. Signal handlers are 
created so that the program behaves in a well-defined manner upon receipt of a signal.

For this task you will provide a program that displays a single integer on each line of output at 
the rate of one integer in each half second. Upon receipt of the SigInt signal (often created by the user typing ctrl-C) 
the program will cease printing integers to its output, print the number of seconds the program has run,

  The "hello world" of neural networks: a simple 3-layer feed-forward
  network that implements an XOR logic gate.

  The first layer is the input layer. It has two neurons a and b, which
  are the two inputs to the XOR gate.

  The middle layer is the hidden layer. This has two neurons h1, h2 that
  will learn what it means to be an XOR gate.

Async/Await for Swift

• Proposal: SE-XXXX
• Authors: Chris Lattner, Joe Groff

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.
