 Well, as you can see, I'm, well, the deaf room organizer for today. We have a very nice program, I think. It was a bit of struggle sometimes because this year quite a few people had to cancel because they had problems with getting visa and things like that arranged in time. But anyway, I hope we still have an interesting program. Just a few things for you. I don't know, who has been at POSDM before? Okay, so more or less half of you, okay? So, okay, let's turn off this sound. Maybe some important things to know. One thing you will see is that we have a schedule which is completely full. It means there is no breaks. If you want to break, you just skip the talk. So choose one which you don't really like or it's not that much into your interest field. The reason why we do that is that, well, there are a lot of deaf rooms and if everyone makes a break at 12 o'clock, then everyone will go to these few places to eat and it will just not work. So that's the reason why we do it like that. Also, we want to give as many people as possible a chance to talk. In case you really want to see everything, there's one person. I think he's building rock climbing maps with OpenStreetMap who indicated to me that actually he wanted to give a short presentation but I gave him a block as long as he was. So his talk will probably be shorter. So maybe that's a good time to skip to run out. Some other things. I don't know if some people are here with a lot of luggage. It's still okay. But there's a cloak room in the K building. Why do I say it? Because at one point the room might be full of people and then if people bring a lot of these big bags and stuff like that, it's getting like unpleasant. Yes. About food. If you want to get food, if you go out, there's like the main avenue. There are a few food trucks who will open soonish and then you can get some things there. Yes. What else? I might just put this. If you go out this building and to the right, there's the H building. There's a small info desk there. There you can get like a flyer with all other things happening at FOSDOM just in case you don't know it. Of course, you can check through the website fosdom.org and look at it from there. Some remarks for the speakers. We have blocks of 30 minutes. The idea is that we have 25 or that we have 20 minutes talk and then 5 minutes or something like that for discussion. And then another 5 minutes where the next one can prepare. You can still discuss a little bit in smaller groups. But then we can definitely start in time. It's important that we start in time because we are parallel with other tracks. Some people they might want to see a talk in another room and then come here so we have to keep good the schedule. And for that reason or another reason is that we are recording. So you can see I'm wearing a microphone. If you go to the website, it's called live.fosdom.org there you can watch all the live streams. So in case this room is full, which might happen you can still pick up a talk there. We will also publish videos of the presentations. Yes. That's the last thing I want to say is that full is full. If we put a sign that the room is full you cannot enter. This is for fire safety measures and stuff like that. So don't make us angry. Just stay outside and wait until you can enter. Well, that was basically my talk. I will now pass the word to Petrien who will be talking about free watch. And he can explain much better than I what it is.
