3. What is Go? #define
4. Go is a board game involving two players, that originated in ancient China more than 2,500 years ago.
6. Go Is … Go is a compiled, type-safe language developed by Google that targets system programing by providing concurrency, garbage collection, and simple cross- compilation.
7. caveat I am not a language junkie
8. Goal: To learn enough about Go to start experimenting immediately
9. Basics ⊡ Google 2009 (1.0 2012) ⊡ Gaining momentum □ Docker □ Heroku □ CloudFlare □ Kubernetes □ Malwarebytes □ Uber □ SpaceX ⊡ compiled ⊡ garbage collected ⊡ concurrent ⊡ type safe ⊡ multiple targets
10. Fast or understandable, pick one.
11. Tradeoffs ⊡ Speed versus simplicity □ Python asyncio □ Node.js ⊡ Ability to onboard new devs ⊡ Concurrency syntax ⊡ How much magic?
12. main.go
13. Primitives
14. slices.go
15. maps.go
16. types.go
17. interfaces.go
18. Why is this interesting?
19. A goroutine is a lightweight thread of execution managed by the runtime.
20. concurrency.go
21. Channels are the pipes that connect concurrent goroutines. You can send values into channels from one goroutine and receive those values into another goroutine.
22. channels.go
23. Go’s select lets you wait on multiple channel operations.
24. select.go
25. type_embedding.go
26. In Brief ⊡ `range` keyword ⊡ Deployment -- cross-compiling ⊡ Testing ⊡ Benchmarking ⊡ Debugging ⊡ Dependency management
27. Closing Thoughts ⊡ How should we evaluate its use? ⊡ Where is it used in Blue Coat? ⊡ New language means new code
28. Questions?
