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.

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...

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).

SECTION 02

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

20. Demo,
weesvc-gorilla

22. What Next?
SECTION 04

23. 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...
