Ruby
• Dynamic

• Object-Oriented

• Dynamic Typing

• Metaprogramming

• Block syntax

Ruby?
•ORM

•DSL

•Fast Development

•Pure performance

Go?
•Strict types

•Compiled binary

•Blazing fast

•Slow development

Web Application
• HTTP Routes

• Database

• Assets Compilation

• Background Jobs

• Export/Import Data

• Deployment

HTTP Routes
• GET

• POST

• PUT

• DELETE

HTTP Routes
• JSON Parsing much faster on Go

• XML Parsing much faster on Go

• Go can process request in goroutine

Database
• INSERT

• SELECT

• UPDATE

• MIGRATIONS

Database
• SQL Drivers is very fast

• Database pools helpful

• Bulk Insert will help you Luke!

Database
MIGRATIONS in Go so UGLYYYY

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

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

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

Assets Compilation
• JavaScript/CoﬀeeScript/TypeScript

• CSS/LESS/SASS

• Handlebars/Mustache

• Gzipping

Assets Compilation
• Sprockets is Ugly

• Gulp is Ugly

• Browserify is Ugly

• WebPack is Not Ugly YET :)

Background Jobs
• Database queue

• Redis queue

• RabbitMQ queue

Background Jobs
• DelayedJob is slow

• Resque is fork based

• Sidekiq is memory eat monster

Background Jobs
• Goworker is Resque compatible

• Go-Workers is Sidekiq compatible

• Your own queue via channels

Export/Import Data
• DSL is your power

• Metaprogramming is your crown

• Pipes is your horse

Deployment
• Docker

• Dokku

• Flynn

• Docker-Compose
