Learning Go
"None of the engineers on the team have taken very long at all to come up to speed in the language; heck, even one of our interns picked it up in a couple of days." - http://bit.ly/14NxLnc
Easy to learn interactively: http://tour.golang.org/#1
Going from Ruby to golang
The creator of Sinatra (the ruby framework we use) now uses Go and has released Sinatra's `Go` successor.
- https://github.com/bmizerany/pat and other projects https://github.com/bmizerany?tab=repositories
"Python and Ruby programmers come to Go because they don’t have to surrender much expressiveness, but gain performance and get to play with concurrency."
- Rob Pike
http://bit.ly/ZGHF9d
- Currently handling > 100 million messages / day
- Experienced Java programmers spent the last few years in Ruby and decided to do a rewrite in Go after evaluating Java, Scala, Node.js and Erlang.
"Our CPU utilization was less than 5% and the entire process started up with only a few hundred KB's of memory (on startup) vs our Rails apps which were ~50MB (on startup). Compare that even to JVM memory usage! It was night and day. "
http://backstage.soundcloud.com/2012/07/go-at-soundcloud/
- Mainly a Ruby/Rails shop that started adding more services in Go.
- "An environment of shared code ownership is a perfect match for expressive, productive languages with low barriers to entry, and Go has proven to be exactly that.[...] All together, SoundCloud maintains about half a dozen services and over a dozen repositories written entirely in Go. And we’re increasingly turning to Go when spinning up new backend projects."

- "Going back to Ruby after working with Go for a week makes me appreciate a fast feedback loop. Ruby Y U SO SLOW? #golang"
https://twitter.com/burkelibbey/status/312328030670450688
- "#golang is quickly becoming the de facto third language of @shopify (after ruby and JS). Pretty excited about this."
https://twitter.com/darkhelmetlive/status/142506549171073024
"It's faster to recompile and run my #golang app from scratch than it is to restart my ruby app doing the same thing."
