Iron.io is an organizer/sponsor of GoSF — a meetup for the Go programming language. We use Go here at Iron.io for most of our server side work and it's pretty darn awesome.
In short, "it's a fast, statically typed, compiled language that feels like a dynamically typed interpreted language." Here's more on the language:
(from golang.org) The Go programming language is an open source project to make programmers more productive. 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.
The first meetup is April 18th. Two top developers, Brad Fitzpatrick from Google and Blake Mizerany from Heroku, will sharing code examples and explaining how Go plays into their algorithms and approaches. Both have built a number of popular high-performance applications, systems, and frameworks and while expert in many languages, are spending most of their time with Go.
If you're around, stop by (location tbd). Given the speakers, it's an event not to be missed.
