Why do I think Go is more 'distributed' than other languages, and why do I think that is a good thing ?

  1. Go does not have a BDFL, there is no Guido Van Rossem, no Theo De Ralt, etc. We have our spiritual leaders like Rob Pike and Ken Thompson, but their influence is much less immediate.

  2. The very nature of the development of the Go standard library discourages adding new stuff to the standard library.

2a. I believe this is a good thing

We're looking for a junior to mid level Javascript and/or Ruby developer to join our team at The Exchange Group.

The Exchange Group is best known for online bike marketplace,, which in the last couple of years has expanded to New Zealand and Germany. We've also added, and to the mix.

The application is primarily Ruby on Rails 3.2, which we're planning on upgrading to 4.0 in the near future. We've brought in AngularJS to several sections of the site already: our new search is entirely Angular. As our application grows, we'll be reducing our reliance on a monolithic Rails application and splitting things into UI & API implementations; this is where you'll come in.

The successful applicant will:
