I will start of talking about why 'working for free' became an importantpart of the developer culture all around the world and talk about whycompanies should try to share as many tools as possible. I'll give someexamples of tools that were open sourced and got immense tractionleading to the projects growing with an intense speed. I'll try to takeaway the 'fear' of open sourcing tools that cost ten of thousands ofdollars to create. Then I'll describe how my journey with open sourcelooks like and start talking about how you can get your feet intocontributing to known projects. After that I will close off with somehints on doing and contributing to open source projects that worked outgreat for me. They will also get an impression on what opportunitieswill show up if they put some of their time into doing OS.The audience can be mixed, but it's way more interesting for people thatare either new to programming or have never worked with open source.In a perfect world, some of the listeners would leave the presentationwith the motivation and hard goal to start with OS as soon as possible.
