Rupher = Ruby+Gopher. Why Ruby and Go can't live without each other, what is the reason and how they complement each other.

1. Rupher

2. Aleksandr Simonov
Developer
DBA
DevOps
TechAddict
Owner

4. James Gosling
Java

5. Ken Thompson & Dennis Ritchie
UNIX

6. John McCarthy
Lisp

7. Larry Wall
Perl

8. Matz && RMS
Ruby and GNU

10. Ryan Dahl
Node.js

11. Rob Pike
Plan9, UTF-8, Go

13. Ruby
• Dynamic
• Object-Oriented
• Dynamic Typing
• Metaprogramming
• Block syntax

14. Ruby’s Unicorns

17. Gopher’s Bullets

20. What to choose?!

21. Ruby?
•ORM
•DSL
•Fast Development
•Pure performance

22. Go?
•Strict types
•Compiled binary
•Blazing fast
•Slow development

23. BOTH!

24. WHY BOTH?!!

26. Web Application
• HTTP Routes
• Database
• Assets Compilation
• Background Jobs
• Export/Import Data
• Deployment

27. HTTP Routes
• GET
• POST
• PUT
• DELETE

28. HTTP Routes
• JSON Parsing much faster on Go
• XML Parsing much faster on Go
• Go can process request in goroutine

29. Database
• INSERT
• SELECT
• UPDATE
• MIGRATIONS

30. Database
• SQL Drivers is very fast
• Database pools helpful
• Bulk Insert will help you Luke!

31. Database
MIGRATIONS in Go so UGLYYYY

32. -- +goose Up
CREATE TABLE post (
id int NOT NULL,
title text,
body text,
PRIMARY KEY(id)
);
-- +goose Down
DROP TABLE post;

33. class CreateAccounts < ActiveRecord::Migration[5.1]
def change
create_table :post do |t|
t.text :title
t.text :body
end
end
end

34. Sequel.migration do
change do
create_table(:post) do
primary_key :id
column :title,:text
column :body, :text
end
end
end

35. Assets Compilation
• JavaScript/CoffeeScript/TypeScript
• CSS/LESS/SASS
• Handlebars/Mustache
• Gzipping

36. Assets Compilation
• Sprockets is Ugly
• Gulp is Ugly
• Browserify is Ugly
• WebPack is Not Ugly YET :)

37. Background Jobs
• Database queue
• Redis queue
• RabbitMQ queue

38. Background Jobs
• DelayedJob is slow
• Resque is fork based
• Sidekiq is memory eat monster

39. Background Jobs
• Goworker is Resque compatible
• Go-Workers is Sidekiq compatible
• Your own queue via channels

40. Export/Import Data
• DSL is your power
• Metaprogramming is your crown
• Pipes is your horse

41. Deployment
• Docker
• Dokku
• Flynn
• Docker-Compose
