The document is a presentation by Paul Balogh introducing the Go programming language, highlighting its simplicity, efficiency, reliability, productivity, consistency, and popularity among developers. It also discusses a project called 'weesvc', which serves as a comparison framework for application development using various languages and frameworks. Finally, it provides resources for further learning and community engagement within the Go ecosystem.
![What Next?
● Finalized “requirements” for functionality
● Compatibility Suite to ensure service compliance
● Updated weesvc-[springboot|micronaut|gokit]
● Website with logo
● Profiling Suite for comparative analysis
And to appease the crowd...
● weesvc-vapor written in Swift
Coming Soon...](https://image.slidesharecdn.com/letsgost-200129020622/85/Let-s-Go-St-Louis-CocoaHeads-23-320.jpg)

- 4. What is Go? SECTION 01
- 5. https://golang.org/ Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
- 6. What is Go? ● Publicly announced by Google in November, 2009 ● Created by Robert Griesemer, Rob Pike, and Ken Thompson ● ThoughtWorks Technology Radar suggests Trial use in 2014; switches to Adopt 6 months later ● Vibrant, inclusive community striving for diversity backed by the Go Community Code of Conduct ● Development language for major Cloud Native projects: Kubernetes, Linkerd, Docker, Terraform, Vitess, etc. About Go...
- 7. What is Go? ● Simple ● Efficient ● Reliable ● Productive ● Consistent ● Popular About Go...
- 8. {Simplicity. Advertised due to the smaller number (25) of keywords and single binaries. In reality, more of a credo than a language feature. “Clear is better than clever.” What is Go?
- 9. Rob Pike … a desire to keep the language specification simple enough to hold in a programmer’s head.
- 10. {Efficiency. Compiles to native machine code (32- & 64-bit x86, ARM). Programs compile fast with a very small binary result. Built with concurrency in mind: goroutines and channels. What is Go?
- 11. {Reliability. Managed memory with Garbage Collection; pointer arithmetic not allowed. `defer` for use with cleanup code. What is Go?
- 12. {Productivity. Large standard library. Strong typing with type inference. Standardized test framework. What is Go?
- 13. {Consistency. Static analysis tools `gofmt` and `golint` for ensuring standard code and documentation format. “Gofmt’s style is no one’s favorite, yet gofmt is everyone’s favorite.” What is Go?
- 14. {Popularity. Go is the #4 language in use in GitHub behind JS, Python, and Java based upon “stars.” A trend driven by high-profile programs in the Cloud Native Computing Foundation (CNCF). What is Go?
- 16. What is Go? Gophers are multiplying! Popularity
- 18. Helps you select an application framework by implementing a common service application with various languages and frameworks allowing for benchmark comparison. Wee S-V-C: a tiny service
- 19. About WeeSVC... Meet WeeSVC ● First repo started May ‘19 with Java/SpringBoot ● Like TodoMVC but for backend (micro)services ● Many implementations; same use requirements ● weesvc-gorilla is currently defining standard ● It’s only me at this time Where it’s headed ● Compatibility tests to ensure requirements met ● Testing with simulated load for profiling ● Website with published profiling results
