history

more or less precise

Until '80 sharing source code was a common thing.

Microsoft (which now loves Linux), AT&T and other big players were boosters to start closing source codes.

Closing Unix source code caused BSD to be born.

Not being able to modify new printer software in his laboratory, Richard Stallman has decided to create Free Software Foundation and GNU Project few years later.

There are loads of different licenses, GPL and less restricted BSD are most common used.

Open Source Software vs Free Software

free as speech, not free beer

Note: There are projects which are based on open source solutions but they aren't free to use Windows GetApp

Note: MacOS is not based on GNU tools! Containers to the rescue.

yes | read -p "should I contribute?"

yes because...

  • you can
  • you already use OSS
  • tl;dr - give back what you've got
  • it's great experience

how to contribute?

  • learn the basics - github and git
  • submit an issue, code contribute
  • join the community (slack), meet great people
  • all skills are welcome

Note: skills - advocates, release managers, code reviewers

big community effort

ways of contributing

  • create your own project
  • create open source alternative to commercial solution
  • contribute to existing projects

outcomes

  • request for features
  • report bugs
  • reach communities outside Kainos, they are so helpful
  • if you can, submit code
  • if you can't code, learn how to - satisfaction guaranteed

Note: Stop creating jobs in Jenkins to do nightly cleanups

You're all engineers, act as ones.
