telling• What• Why

Do it in *your* project

✴in English, of course

Pro Tip #4

English

Why are you scared?

✴We had been learning English for 6～ years

✴We’re speaking Ruby everyday✴There are only 26 letters

✴Know these 26 letters✴Aware of the accents

Watch Railscasts

Pro Tip #5

Live on the edge

edge is fun

✴As you’re reading edge every day,

✴Can’t wait to try these great new features until stable release

Just bundle it

✴gem 'rails', :path => '~/src/rails'

Yes, Bundler! <3 <3 <3

Pro Tip #6

Contribute to the documentation

docrails

% git clone lifo/docrails

docrails

A special Rails fork just for contributing

documentations via GH

Rules

✴Anyone can commit✴No code. Documentations only

(guides / code comments)✴Commit to master branch

directly

Let’s start with a minimal contribution

For example,

“s/a/an/g”https://github.com/rails/rails/commit/90887cb

Anyone can do this if he/she knows how to

use grep & sed

Pro Tip #7

Share your monkey patches

Push it to the upstream

That’s the absolute way to make the world

happier.

✴local monkey patch => makes only your app better

✴push your patch => makes the whole world better

Lonely Monkey Patches

Rails

Social Monkeys

Rails

Stop writing “how to workaround”

on your rubbishy H◯tena blog

Push the patch instead

Please.

fork Rails, push, and send a pull request

Pro Tip #8

Start from a gem

not only using edge Rails,

use edge Gem

% gem up% bundle update

for your health

% gem i [any gem] --pre

is also a good challenge

add a feature!x a bug

request for a feature

Gems I wrote patches for

https://github.com/amatsuda

Pro Tip #9

Write a good README

Kaminari

Pro Tip #10

Attend RailsConf

RailsConf✴Everyone you see in the `git log`

is there✴Meet your Rails heroes✴For a Rails otaku, RailsConf

would be far more exciting than RubyConf

One more thing

Pro Tip #11

Write a book

You will !nd tons of bugs, typos and

incompatibilities

So you can !x them

that’s called

BDD

Book Driven

Development

B-D-D!

No, I’m not talking about “VDD”...

Summary

Code Ruby socially and get yourself involved in

“the community”
