     7  The Go programming language is an open source project to make programmers more
     8  productive.

    11  <p>
    12  Go is expressive, concise, clean, and efficient. Its concurrency
    13  mechanisms make it easy to write programs that get the most out of multicore
    14  and networked machines, while its novel type system enables flexible and
    15  modular program construction. Go compiles quickly to machine code yet has the
    16  convenience of garbage collection and the power of run-time reflection. It's a
    17  fast, statically typed, compiled language that feels like a dynamically typed,
    18  interpreted language.

    37  <p>
    38  An interactive introduction to Go in three sections.
    39  The first section covers basic syntax and data structures; the second discusses
    40  methods and interfaces; and the third introduces Go's concurrency primitives.
    41  Each section concludes with a few exercises so you can practice what you've
    42  learned. You can <a href="//tour.golang.org/">take the tour online</a> or
    43  <a href="//code.google.com/p/go-tour/">install it locally</a>.

   167  Three things that make Go fast, fun, and productive:
   168  interfaces, reflection, and concurrency. Builds a toy web crawler to
   169  demonstrate these.

   172  <h3 id="go_code_that_grows"><a href="//vimeo.com/53221560">Code that grows with grace</a></h3>
   173  <p>
   174  One of Go's key design goals is code adaptability; that it should be easy to take a simple design and build upon it in a clean and natural way. In this talk Andrew Gerrand describes a simple "chat roulette" server that matches pairs of incoming TCP connections, and then use Go's concurrency mechanisms, interfaces, and standard library to extend it with a web interface and other features. While the function of the program changes dramatically, Go's flexibility preserves the original design as it grows.

   177  <h3 id="go_concurrency_patterns"><a href="//www.youtube.com/watch?v=f6kdp27TYZs">Go Concurrency Patterns</a></h3>
   178  <p>
   179  Concurrency is the key to designing high performance network services. Go's concurrency primitives (goroutines and channels) provide a simple and efficient means of expressing concurrent execution. In this talk we see how tricky concurrency problems can be solved gracefully with simple Go code.
