Go is expressive, concise, clean, and efficient. Its concurrency
mechanisms make it easy to write programs that get the most out of multicore
and networked machines, while its novel type system enables flexible and
modular program construction. Go compiles quickly to machine code yet has the
convenience of garbage collection and the power of run-time reflection. It's a
fast, statically typed, compiled language that feels like a dynamically typed,
interpreted language.
Installing Go
Getting Started
Instructions for downloading and installing the Go compilers, tools, and
libraries.
Learning Go
A Tour of Go
An interactive introduction to Go in three sections.
The first section covers basic syntax and data structures; the second discusses
methods and interfaces; and the third introduces Go's concurrency primitives.
Each section concludes with a few exercises so you can practice what you've
learned. You can take the tour
online or install it locally with:
$ go get golang.org/x/tour
This will place the
tour
binary in your workspace's bin
directory.
How to write Go code
Also available as a screencast, this
doc explains how to use the go command
to fetch, build, and install packages, commands, and run tests.
Editor plugins and IDEs
A document that summarizes commonly used editor plugins and IDEs with
Go support.
Effective Go
A document that gives tips for writing clear, idiomatic Go code.
A must read for any new Go programmer. It augments the tour and
the language specification, both of which should be read first.
Diagnostics
Summarizes tools and methodologies to diagnose problems in Go programs.

Talks
A Video Tour of Go
Three things that make Go fast, fun, and productive:
interfaces, reflection, and concurrency. Builds a toy web crawler to
demonstrate these.
Code that grows with grace
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.
Go Concurrency Patterns
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.
Advanced Go Concurrency Patterns
This talk expands on the Go Concurrency Patterns talk to dive deeper into Go's concurrency primitives.
