gb, a project based build tool for the Go programming language | Dave Cheney
A few months ago I introduced gb as a proof of concept to the audience at GDG Berlin. Since then, together with a small band of contributors and an enthusiastic cabal of early adopters, gb has moved from proof of concept, written mostly on trains during a trip through Europe, to something approaching a usable build tool. This post gives an introduction to gb, and explains the benefits of adopting

Go 1.4 Release Notes - The Go Programming Language
Introduction to Go 1.4 The latest Go release, version 1.4, arrives as scheduled six months after 1.3. It contains only one tiny language change, in the form of a backwards-compatible simple variant of for-range loop, and a possibly breaking change to the compiler involving methods on pointers-to-pointers. The release focuses primarily on implementation work, improving the garbage collector and pre

Goji - A web microframework for Golang
What is Goji? Goji is a HTTP request multiplexer, similar to net/http.ServeMux. It compares incoming requests to a list of registered Patterns, and dispatches to the Handler that corresponds to the first matching Pattern. Goji also supports Middleware (composable shared functionality applied to every request) and uses the standard context to store request-scoped values. Quick Start Install Goji by
