Advantages

Why participate ? (don’t be shy, we NEED your help)

- project maintainer is a bottleneck => need more trusted maintainers- steer the project to match your needs- be proud of doing something useful => you reach this step once you realize you start to give away your code- be happy to do something fun- improve your skills- meet other cool people- sometimes, find a better job

88

Advantages

How to participate- read CONTRIBUTING- subscribe to the mailing list- “janitor” work / help others- participate to design discussions & workshops, your opinion matters- read the docs and propose fixes / improvements- try to reproduce reported bugs, send “me too”- try development versions and report failures and/or success- try RFC patches and report failures and/or success- try to find the cause of reported bugs- review posted patches and explain how to improve their quality- propose cleanup patches for existing code- propose bug fixes- announce your intent to work on some features, then propose patches- become a maintainer

99

Advantages

How to piss off the community- send a patch and disappear- send a patch not respecting the basic rules in CONTRIBUTING- send a github pull request- send a patch for anything but the latest mainline branch- give wrong advices to people who seek help- help people who do not respect others
