Go Lang is a programming language that is general purpose, compiles code quickly, and is strongly typed. It includes features like goroutines for concurrency and tools like go get, go test, go run and go build. Resources for learning more about Go Lang include its official website, an interactive tour, books and blogs.

Editor's Notes
- #3: Personal opinion My history
- #4: Starts on late 2007. Became open source in November 2009 Today's version is 1.7.4 Key Players: Robert Griesemer (Hotspot, JVM) Rob Pike (58) (Unix/UTF-8) Kenneth Thompson (71) (B and C lang/Unix/UTF-8) Ian Lance Taylor (GCC) Russ Cox (Plan9/CSP) Solve big problems at google such as: thousands of engineers, C++ on servers, distributed build system, maintainability, big scale
- #5: Expressive Comprehensive Sophisticated
- #6: Garbage collection Remote package management Great builtins No exceptions :O! Among others...
- #10: Gzip Reflect Math Unicode Image Net/mail Net/http Json Crypto/Aes HTML/Template ------------------ Live coding: webserver example from scratch -> interaction with log.fatal (ie 2 ws on the same port) - webserver.go

- #12: You can define concurrents units of executions (concurrently execution functions) Apps uses all cores - Can run on multiples cores at the same time No limits NON BLOCKING IO!!! Can communicate & sync via channels Demo -> 1 & 2 process - goroutine.go
