Richard Stallman & Linus Torvalds :neckbeard:

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

Its fun and unexpected stuff happens!

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.

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 :trollface:
