 Okay, this is Tup. I'm Buk. We make some shameless advertisement for a new rocket application since already a few rockets with you. I guess we build a dating app for the rocket. And a slide, please. This is of course very important because dating seems to be a hard problem and it involves some awkward social situations. You need to get close to people, physical proximity and talk to them. And maybe in the end they don't share your views on cannibalism or anything. So it's good to know before. And of course as all social problems they have a technical solution. And this technical solution is our application. Slide, please. There is a dating site in the Wiki. The dating site is not very well populated. There is four categories or five categories for human dating. And there are three entries in there in total. So that's more categories than actual entries. And we want to get this up. So... Is there a section for carbon dating? Repeat the question. Is there... A section for carbon dating? Carbon dating, like every live form based on carbon. I didn't get it, sorry. Okay, so we have this great new application and you can check it out. Slide, please. On our website, download it now and put it on your rocket. And in the meantime, Tobias will explain to you how it works. So the basic idea of, okay, rocket is you create a profile of your preferences and this profile is broadcasted to other users who also have this application running. So it's very simple. You go to the website, you download the code file. If you don't trust us, download the C file and compile it yourself. And put it on your rocket by just copying it using USB mass storage mode. And then you're asked to fill out a small profile consisting of 14 binary questions. So, like, what chromosomes do you have? What chromosomes would you like your partner to have? If you're like, we are your e-mags, docks or cats, and so on. So this creates a small bit string that is just broadcast to your vicinity along with the nicknames of other people having the application running. And then you instantly see a list of people and how much their profile matches yours. And if there's someone whose profile has a more than 80% match with yours, then the red LED starts blinking. So you should have a look around and see if there's any other people who have the red LED blinking and then you should go talk to them. So, okay, so this is the camp rocket and the current rocket have another position for the red LED. So you should say it's the down left. Okay. So this is the bottom left LED is the red one on the 28C3 badge and on the camp badge it's green. Yeah. Okay. So, yeah. Download the app. By the way, next slide. We actually did a field test and it works. So, okay, this couple wasn't made with the application but they were asked to install it on the rocket and they completed their profiles and indeed the red LED started blinking for them so that confirmed that our questions work or that, yeah. So, yeah, super sufficient. Yeah. So, fork it, create your own version of it, download it, play with it and hopefully find people who you like and who like you. Our network has currently two players. Extend time. Extend time. Any questions or go for a field test maybe? You can easily extend the questions so you can set up other things from dating. So, one person yesterday suggested to us that we should make a flame war version of it so you can go around and your flame starts blinking as soon as it finds someone with a different view on the favorite editor. So, that's very easy. Send us pull requests or something and we get out more versions.
