How to contribute code to an open source project

  • Identify something

to fix

  • Find the repository
  • Install new trendy

source control tool

  • Check out

repository

  • Find build

instructions

  • Install the right

build tools

  • Build attempt #1
  • Install missing

dependencies

  • Build attempt #2
  • Install more missing

dependencies

  • Build attempt #3
  • Something’s wrong

with the makefile

  • Who the hell

understands make anyway?

  • Google
  • Find and apply

makefile fix

  • Build attempt #9
  • WORKING APP!
  • Search source for

bug

  • Read API docs
  • Fathom API docs
  • Create fix
  • Test fix
  • Enjoy fix
  • Create patch
  • Submit patch
  • Wait for patch

merge to trunk

  • Wait some more
  • Snark about

maintainer

  • Start nagging
  • Meanwhile, build on

fix, make more patches

  • Provide own

tarballs

  • Multiple anguished

flamewars

  • Fork

Folk Programming is...

  • The social life of code
  • How it breeds, travels and evolves

> exam rube Rube Goldberg contraption (aka #6498, Rube Goldberg contraption, Rube Goldberg, and contraption) Owned by Aladdin. An incredibly complicated contraption. There is a lever on one side. A sign

  • n the other side says "To run contraption, 'pull lever on contraption'; to

add parts to contraption, first 'enter contraption'" Obvious verbs: en*ter rube g*et/t*ake rube d*rop/th*row rube pull <anything> on rube > pull lever on contraption Rosy_Guest pulls down the handle on Rube Goldberg contraption. The lever pulls on a string, releasing a steel ball high up. The ball enters a maze of passages. Somewhere deep inside, the ball hits a switch with an audible click. A large television comes to life, showing re-runs of "Gunsmoke." The sheriff's bullets fly out of the screen A Kung Fu master catches them in his teeeth. The subtitles read "I should've ordered glutinous rice chicken!" He spits out the bullets, which fly toward poor Mel Torme. Sorrow drifts over the land for the death of Mel Torme. ...and now for something completely different... A gigantic puffball bursts, filling the air with spores. A hush falls over the contraption; everything has stopped. A horde of monkeys runs all over the contraption, setting everything back sort of the way it was.

What’s the power here?

  • 1. Create your own code
  • 2. View, clone and modify someone else’s code
  • 3. Free, always-on, ubiquitous hosting
  • 4. Huge array of diverse data sources/objects
  • 5. Code creates new data for use by others

There is strong social pressure against forking projects. It does not happen except under plea of dire necessity, with much public self-justification, and requires a renaming.
