My favorite talks at GopherCon 2014:

• Peter Bourgon: Best Practices for Production Environments Soundcloud were an early Go adopter, and this talk is their distilled learnings from two years of Go: Repo structure, config, logging, testing, deployment, and lots more. The one talk you need if you’re starting (or running) a significant Go project, and you want to do it right.
• Petar Maymounkov: The Go Circuit: Towards Elastic Computation with No Failures Stick with this one. It starts off quite academic, but gets fascinating very fast. He models whole companies as a distributed system (based on CSP), then builds a language-agnostic cluster programming library where the API is a filesystem The Circuit. One of the highlights of the conference for me was building a filesystem with Petar in the hallway.
• John Graham-Cumming: A Channel Compendium John is the author of those great in-depth Cloudflare blog posts. Solid talk about Go channels. nil channels always block, so you can ‘disable’ a select clause by setting a channel to nil. Closed channels never block. Heartbeat is just time.Tick, timeout is time.After. Go programs are small sequential pieces joined by channels.

Those are the three talks I enjoyed most. Here are my general notes on the conference and a few of the other talks.
