Two types (OSS project) founders…

A. Nurture and converse “Do you care?”

B. Previously A “Do it yourself”

Life as an A-type is awesome…

Life as an A-type is awesome… until it is not

“Saying Goodbye”

Jamis vs Dr Nic Proof of Jamis’s awesomeness Downloads 500000 375000 250000 125000 0 Capistrano Composite Keys NewGem RubiGen source: http://gems.rubyforge.org/stats.html

! Disclaimer My projects aren’t wildly popular

80 60 40 20 0 mid-2007 mid-2008 mid-2009 I just have heaps of them

Some formulas… X projects/yr x 40 years = ? 5 projects/yr x 40 years = 200 25 projects/yr x 40 years = 1000 1000 projects x ½hr/wk = 500hr/wk There are only 168 hrs in a week

OSS projects don’t scale but neither does raising pets nor children

A dog trainer having a pet dog vs maintaining many dogs

A teacher having a pet child vs maintaining many children

An OSS owner having a pet project vs maintaining many projects

What to maintain? pet projects and libraries you need each day

and abandon the rest http://www.ﬂickr.com/photos/robbyrussell/243693247/

Maintenance Goal: Zero Effort

Aim: Manage expectations

• Publish project status • Facilitate group therapy • Forward emails to mailing list Aim: Reduce bad karma

Aim: Community self-sufﬁciency

Centralised patches

$ gem install defunkt-github # super lazy $ cd your/project $ gh pull username --merge $ rake test $ git push # update History.txt for next release Use: Command line tools

Add: Admins/contributors

Aim: Zero maintenance cost

require 'rubygems' gem 'hoe', '>= 2.1.0' require 'hoe' Hoe.plugin :newgem Hoe.plugin :cucumberfeatures Hoe.spec 'looksee' do developer 'George Ogata', 'george.ogata@gmail.com' end Packaging: Hoe/Echoe for Gems

ChocTop.new do |s| s.host = 'commitchat.com' s.base_url = 'http://commitchat.com/dl' s.remote_dir = '/opt/apps/commitchat/dl' s.background_file = "dmgbg.png" s.volume_icon = 'VolumeIcon.icns' s.app_icon_position = [106, 83] s.applications_icon_position = [422, 83] s.applications_icon = "dmgappico.png" end Packaging: ChocTop for DMGs

Packaging: ChocTop for DMGs

• Test frameworks: ............... • Reuse processes: rake • Create tools: newgem • Promote your process: blog Aim: zero process cost

5 mins to run tests 30 mins looking at bug reports Aim: zero defects

5 mins to run tests 0 7.5 15 22.5 30 30 mins looking at bug reports Aim: zero defects

$ cucumber features/development.feature Scenario: Generate RubyGem Given this project is active project folder And "pkg" folder is deleted When I invoke task "rake gem" Then folder "pkg" is created And file with name matching "pkg/*.gem" is created 1 scenario (1 passed) 6 steps (6 passed) QA test packaging

Aim for zero • Don’t use it? Don’t maintain it • Manage expectations • Community self-sufﬁciency • Zero process cost • Zero defects

Use your spare time • Find a hobby • Talk to your spouse • Create more projects

Create a new project newgem my_project cd my_project git init git add . git commit -m "initial" github create-from-local
