 Hello, thank you Actually, I decided to forego slides entirely just that I can squeeze a thought a single thought into these five minutes a Thought about something that suzer cares about and let me start with the story. It was in 90s sometime still before my suzer time That two friends of mine were developing a interesting project. It was a hardware project It was a free space optic device that would allow a 10 megabit Bandwidth across a couple hundred of meters for internet connection It was it in the time of dial up So that was actually pretty amazing and they had it working and they wanted to attract the community to it some somebody That would help them to actually expand it and make it work better So they were coming to me and said well, you know, we saw this open source software movement We want to do something like that And I said, okay. Well, then you just publish the source for your device and that's it, right? But what is the source for a hardware device? So initially they just published the list of materials all the steps that you needed to make the device this the actual Photos of the machine and well nobody really did that because nobody did understand how it works So then they talked to me, okay But that's not enough you actually need to go deeper. You need to publish at least the schematics So the schematics was out. It was actually done in a nice open source Open data format such that you could use open source tooling to do all the steps to create a printed circuit board and make your device And still that didn't work so They were flabbergasted right there was there was all all out there and there was nothing and So the last thing actually You need to explain why it works the way the way it works. Why have you designed it? Why have you added this particle component here and that particle component there because without that understanding? nobody can really expand on it and Actually that worked that device became rather successful until well Wi-Fi came around and It was a happy project so Where this brings me um? if you are Doing open source It is important to be open. It is important to actually give out everything that you have all the thoughts that are going to do that Go into your project Not just the source itself Fortunately today we have Source code repositories we have get we have subversion we have all those so actually a lot of that thought goes right into the commit commands so The gpl actually nicely captures that you need to share your source code the gpl v3 Actually nicely captures the fact that what the source code is that it is actually the form of the code that is the easiest for modification But still it does not tell you that the one component that is also needed is the how component How do you come to these conclusions? How do you actually find out that this is the best software? This is the best way to do it and Well, that's the message that I want to share today actually I'm also a manager right and so I've been taught that if I want to keep a Developer a employee working for me I need to teach them everything they need to know for the next job and then they will not leave because they are all Safe, so it's the same thing for your project. You actually need to give out everything for people to be able to fork it And that's what makes it healthy Um once more about Susie we actually do practice that at least we try and So when my department is releasing the Linux kernel For customers obviously paying customers. We also release the sources and we don't just release the SRPM with One big terrible of kernel sources and one huge patch of what we have changed But we actually already during development make public or of our internal git repository so that you can see What and why we changed along the road to make an enterprise quality distro You actually are able to replicate all that if you like and so again the message to you is It's the nature of people it's a nature of business That people try to keep the secret source to themselves Don't do that. It is counterproductive If you see wall gardens being built For contribution if you see that customers are actually not treated as potential contributors to the project Tear down those wall gardens and always think about being open. Thank you
