Richard Stallman & Linus Torvalds

Completely different views on open source. Even though both are considered open source “heroes”.

I didn’t want code, I wanted comments. - Linus Torvalds

If you use a proprietary program, you’re defenceless. - Richard Stallman

What is your motivation?

Its fun and unexpected stuff happens!

Two stories of my own

Writing a brainfuck interpreter in a 20-day-old language.

Vivaldi - Hacker News

Current examples

I wonder if I can write a

brainfuck interpreter with Vivaldi

🤔

Github issue #1

Archiving certain USGOV sites in response to Trump

Professors were scared that the Trump administration would withdraw funding for certain gov-sites.

They started mass-archiving sites to the Internet Archive.

Big open source™

Modern open source
- Google (TensorFlow, Kubernetes, Angular, …)
- Facebook (React, HHVM, jest, …) and what about their patent-clause?
- Microsoft, yes Microsoft.. (dotnet, vscode, TypeScript, ..)
Could open source be used in new places?
- Outside of software?
- Open source banks? governments?
- Why aren’t governments institutions open sourcing their code???
  - WHY?!?#!@#^!

Contribute to open source

How can I get started contributing?
- Contributing to a OSS project
- Building a OSS project

How can I get started contributing?

Contributing to a OSS project
- Start small
- Read some old pull requests and issues
- Validate that your change is needed
- Be nice
- Spend time on writing good issues and pull requests
Building a OSS project
- Build something yourselves
- Being a maintainer can be hard
- People are not always nice

Remember the code from the first slide?

include OpenHack

author = Presenter.new(:buren)
slides = OpenSource::Slides.new

wait until author.ready?

author.present(slides) do |slide|
  print slide
  any_questions? if slide.last?
end

DEADLINE = Time.new(2017, 6, 3, 14, 30, 0).freeze
module OpenHack;end
module OpenHack::OpenSource;end
String.class_eval { define_method(:last?) { false } }
NilClass.class_eval { define_method(:last?) { true } }
define_method(:wait) { puts 'Still not ready..';sleep 3 }
define_method(:any_questions?) { puts 'Any questions?' }
define_method(:feedback) { puts 'Feedback?' }
class OpenHack::Presenter < Struct.new(:name)
  define_method(:ready?) { Time.now >= DEADLINE }
  def present(slides); slides.to_a.each { |slide| yield(slide) };end
end
class OpenHack::OpenSource::Slides
  define_method(:initialize) { @slides = File.read('slides.md').split('---') }
  define_method(:to_a) { @slides + [nil] }
end

This actually makes the previous code work
