 ich weiß nur zwei Dinge über den nächsten Talk. Der erste ist, es wird kurz dunkel, nicht erschrecken und nicht hinfall währenddessen. Der zweite ist, es sind acht Mikrokosmen, acht Experten und je acht Minuten. Was weiter passiert, werden wir sehen. Einen großen Applaus bitte. Willkommen zu der Englischen Übersetzung. Welcome to the English translation of bits and trees live from the 36th case communication congress in Leipzig. Your translators are Goonies bro, Snakey and Mio. Sporangium from the Greek, a vessel, a approximately spherical container in which the spores are created. The sporangium, a vessel from Greek, an almost spherical container on ferns in which the spores are created. In most cases, sporangia have a special opening mechanism in order to spread the seeds over the greatest distances possible. The sporangium of the gold serpent fern around the spore containers of the golden serpent fern curled a row of cells with strong inner walls and thin outer walls. Initially the cells are filled with plenty of water, but as the spores mature, they gradually dry out. The pressure inside the cells changes due to the evaporating water. When a critical value is reached, a phenomenon occurs called cavitation. The formation of bubbles inside the cells, the cells expand, the strong inner walls now act like a spring under tension. They bend the cell now in the opposite direction. The catapult is loaded. Now the spores are thrown out of the spore capsule at up to 10 meters per second, where the spores fall on fertile, so new gold serpent ferns can thrive. Welcome tonight in Borg. Thank you for coming here either on feet or per data. We're happy you've chosen to make the experiment and share tonight. We are Reine and Juliane. Reine, what is it you're doing here and what has this to do with bits and trees? Well, nice good you're asking. Well, I myself call myself a critical computer scientist and I am active in several fora. What we do is make complex technology understandable. We will contextualize everywhere where technology is relevant for society. That's where we come in. This is for fair IT, cyber IT, data privacy. Well, so I am a critical and informed scientist at the Open Knowledge Foundation. What we do is we explain technology and make sure that people can discuss technology, that technology is democratized and it's shared and that civil society can share technology. Open source or Fragtenstadt or youth hacking. Yeah, so we, FIFF and UKF, have in 2018 with other organizations in Berlin started this project. Other organizations, what that means is this is techy organizations like the CCC, but also organizations from environmental activists. The Boat für die Welt, German Watch und also netzpolitik.org. What do we do though? So, first we discovered we're all activists and the idea of bits and trees is that the techies and the eco have the same goals. We all live in this world, not just some random people. And what we need for this is a planet that is inhabitable tomorrow by humans under, with human conditions. What we also need is rooms, is spaces that are not subject to, where can we find the basis for this on a party? Right, so party after a conference. A party where everybody abounds with knowledge. That was the conference, bits and trees. And since then the BUND has helped to bring open source forward and is behind this idea just like the CCC has subscribed to the goals of environments. This happened a year ago, so what happened since then? Well, so. The fruit of our projects are address books. What we do, we help the track of resilience and sustainability. And also there are CCC internal groups like Sustainability groups. So what do we do today on this stage? What we'll do is just like a report today. Like the Spurangia spread knowledge at high speed into this room and into the world such that we can all flower and bloom. How does this happen? Well, we will see eight people on the stage that have eight minutes each to spread their knowledge into your brains, into your heads. So to make sure that only eight minutes are used, we have a watch here that will keep the time. So on the other side of that we see the Timekeeper. Welcome. All right. So, he spoke about automatic video surveillance. It can be seen at media CCCD. This is Banks. Banks has the time cards that you will see to be in the suspense as well. I think that's all for now. All right. So, onstage, please, our first Spurangia. All right, please hit the buzzer. Thank you very much. Jetzt, now. Hello, Katrin Heneberger. Nice to meet you. Please give her a round of applause. Katrin, you've come just from the Rhineland. And some of you may know her. She's active at the Hambacher Forest. And she's the media liaison for the climate activists and the Gelände. And you've been protesting against the coal company RVE. So, they have tried to threaten you with all kinds of legal measures, but that didn't work. Did it? Because you're still here and you keep protesting, and we hope you keep on protesting. It's not just that. You're also generally an expert in this climate crisis questions. And she told us before we should avoid the word climate change. Please tell us why, because I think it's very important. Well, we shouldn't use climate change anymore, because it's a very soft word. If we talk about change, it's a very gradual thing. But this is a crisis now. It's a very existential crisis. And how we treat these things is how we talk about these things. So, if we talk about the climate crisis or the climate catastrophe, it becomes suddenly more urgent. Well, from school I know this as global warming, which sounds pretty cuddly. But there's a lot of things happening, which we're going to hear about. Other than defending a favorite forest, you've been to the UN climate conferences for ten years. And you're working for indigenous action and the gender action plan. And you're working for a sustainable future. Now, I'm not going to talk much longer, but we're going to hear now what's going wrong in this world, in our world. So, three, two, one. Sporangium. Our house is on fire. Greta Thunberg sat this about a year ago, and she prophesied what was going to happen in 2019. In summer we have seen the Arctic tundra burning. This was something scientists had predicted for the year 2019. At the same time in the equatorial, the Amazonas rainforest was burning. They are partially still burning. And today in Australia we have crazy bushfires. Our planet is burning already. Our house is on fire already. This is actually not very surprising. Here you see a little video from NASA. It started in 1880, how the temperature changed in the past hundred years. And we are already living in a world where we're about one degree warmer than it should be. And this is a huge problem. One degree Celsius doesn't sound like much. It's not even a reason to wear another sweater. But for the global climate system works different from the weather. A very small number of degrees decides if we have glaciers in Berlin or if our coastal cities are drowning. And there have been some abrupt changes in the world climate in our world history. But those all have in common a great mass extinction of species. And I would like to say we're at the beginning of the next mass extinction in our global history. But actually we're right in the middle of it. In 2012 there have been studies from the World Bank that said if we continue on, if we don't reduce emissions, we're going to head for a world that is four to six degrees warmer. Since 2012 we haven't done much. The situation has worsened as pertaining to the global emissions. And here we have a map, how the world would look at four degrees warmer. The yellow and brown zones are non-habitable zones. People always tell me, yeah, yeah, but we can adapt, we can develop technology. We're not going to the high rises in Siberia. We're going to move to Siberia, to Antarctica or we're going to Mars. But this is all bullshit globally. If we don't act now, if we let global temperatures rise by one and a half degrees or even two degrees, then we're going to have feedback. And we're going to read tipping points. The most famous one is the Tundra in Siberia or Canada. If this starts thawing, then a lot of methane and carbon dioxide is going to be released to the atmosphere. And this is going to worsen the climate crisis. Another tipping point is the Greenland ice sheet. If this goes away, this huge mass of ice, then the climate has one cooling effect less because ice reflects the solar beams back into the atmosphere. And also sea levels are going to rise by about seven meters globally. A third tipping point is the Amazonas, the rainforest there. It is going to turn into a step into grassland in the long term. So this is what you see in this picture now, the nice and green rainforest. This is going to turn into sand and dust. This was three tipping points. There are more tipping points all over the world, as you can see by the Potsdam Institute. This shows how vulnerable we are. And if we don't act now, then it's going to be too late very soon. But why do we fail in the face of this climate crisis? Why don't we do what needs to be done? There's two reasons for that. The first one is that there's a small, rich part of the population who profit from the burning fossil fuels and from exploiting human nature. And they keep telling us that if we try to change the system, then our world is going to go to ruin. But we're all nice and we believe them. And we don't dare to start a David versus Goliath fight. Because especially us in the north, because we're in a rather cushy position and don't feel repercussions yet. Every day, cruel reality is the climate crisis already. Because we keep talking about like this is in the future. Because we're still in denial. We recognize the saber-toothed tiger and we act. But we don't act if this threat is going to happen at some point in the future. We are very bad at anticipating these things. And this is another reason why we don't act now. The climate crisis is not a danger of the future. It's the cruel reality. For example in Chad in the South Zone in Africa. And the heat waves have increased in number and in frequency a lot. Over 50 degrees. This is dangerous for children, the pregnant and the elderly. And this, of course, worsens the conflict between different ethnicities about the last remaining bits of fertile soil and the fights about soil. Water is running out there. The most hardest hit are the women and the indigenous people. Here we can see indigenous people. And the women are responsible for getting water and wood. And their ways are getting longer due to the climate crisis and this is a huge security risk. And their cows produce less and less milk. And if there's not a lot of food during the day, it's the women who give their food to the children first. Overall it's women in these communities, especially in the global south. And women are hit the hardest in these regions by the climate crisis. But they have the least voice at the negotiation table. Their voice isn't heard, especially at the UN climate conferences. This made me aware. I was made aware of this at the UN climate conference in 2010 when there was a typhoon in the Philippines and my colleague Chanel from the Philippines couldn't call her family and her friends for days. And we didn't know are they still alive, are they not? And at the same time we saw the governments accomplish nothing and that made me really very angry. And it showed me we can't rely on anybody. Nobody is going to come save us. We need to act ourselves. The climate crisis needs stopping. And this means we need the action of every single person on earth and every single person in this room. Use your abilities, do something. In the Rhineland we have the Hambacher Forest. We've occupied it. We could successfully stop deforestation here. The activists have been taking to the streets so the coal mine every day for six years. They use their bodies to stop the mining. And this shows that we need to do something here even in Germany and you need to cross the line of legality. You need to do illegal things here sometimes to show the people how dangerous the situation is. But unfortunately they keep on. Instead of a coal exit, we're going to get a new coal power plant next year. It's going to go online next summer. And we're going to need all your help to stop this. The next months are going to be very loud. We're going to have a lot of protests. And we have a greeting from Brazil. It's almost too late for concrete actions. We can't wait anymore. I wanted to introduce her. She's the President of the Indigenous People's Coalition. So we have your voice from the Global South. And this is why we have this video message here. It's almost too late for concrete actions. We can't wait any longer. Mother Earth can't wait any longer. The Earth isn't longer blue and green, but it's deep red. We have to stop this bloodshed. We, the Indigenous People, can't pay the price with our lives any longer. Just to keep the consumer society going. The moment to act is now. We can't wait for 20, 25 or for 2030. We need to act now. It's a bit of a mess, but I guess for that message, our number guy was lenient. You need to pay attention to the time. Or we're going to kick you off the stage at some point. This can't continue. It's okay. We were patient. Don't worry. It's not just bad news. Sie können diese 8 Minuten zeigen, dass Sie die Konsequenzen des Klima-Changes zeigen. Sie können diese zu deinen Freunden, Familien und Nachbarn nehmen und mit ihnen in die Städte auf den nächsten Klimaprotest. Vielen Dank, Katrin, für diesen Brief-Overview. Sie können jetzt mit den Banken übergehen, aber bevor das ... Ich wusste, dass es zuerst sein muss, aber wir müssen die nächste Person wählen, die uns über ihre Spurangien erinnert wird. Bitte klicken die Ente-Button. Tension wird erhöht. Okay, ich denke, er wird uns wissen, was es ist. Also, wir sind mit dem Klima-Krisis. Jetzt haben wir jemanden, um zu sprechen, der eine Bedeutung ist, die sehr wichtig ist, um die Energie-Sektion zu ändern. Natürlich wissen wir, dass das eine der größten Sorten der CO2-Elektronik, die wir haben, und wir müssen das ändern. Manchmal funktioniert das und manchmal weniger. Es ist wichtig, dass wir viele Informationen und öffentliche Informationen haben. Aber das ist nicht immer der Fall. Es ist schwer zu finden, wofür die Ökologischen Energie-Providers sind, die eigentlich ökologisch und grün sind. Wir möchten für das Transparenz sein, damit wir die Ökologischen Energie-Provider, die wir eigentlich machen können, bekommen? Oder ist es wirklich ein CO2-Energie-Provider? Wir haben ein Gesetz, wie in allen diesen Cases. Aber wenn man diese Informationen bekommt, sind sie sehr interessant. Aber oftmals sind sie satt und oft mit großen Gäben. Das ist warum in dem nächsten Gespräch Lisa Passing erzählt uns, warum ECO-Energie nicht die gleiche als ECO-Energie ist, sondern die grüne Energie-Rabbitale. Hallo Lisa. Okay, Lisa, willkommen. Gut, hier zu sehen. So Lisa developst Software as open-source developer, she also codes video games. She also shares her knowledge and her abilities in coding workshops for underrepresented crypto workshops and digital defense. Her long goals are destroying the patriarchy. Welcome. Good, we all believe the same thing here. ECO-Energie, well, I think Katrin should first sit down. Do you know how these things look like, what they are? So, these are air snouts. So Katrin will get an air snout to be able to blow her off the stage. This is not aggression. Please, Katrin, sit down. And if this time really will hold up the zero, you can please trump your snout. Okay, ECO-Energie. Two, one, zero, Sporangium. Okay, off we go. This talk will give you an introduction into our research on ECO-Energie, some context. I work at the data school. This is a project of Open Knowledge Foundation, lesser known. We give workshops to data and also workshops for NROs. Where do I find data? How do I clean the data? How do I analyze the data? That's one part of what we do. The other part is that we cooperate in projects that have to do with data and help them, whatever that means. So, our current project is Robin Wood. Robin Wood, every few years, published an ECO-Energie-Report and answered the question, which ECO-Energie efforts are really worth a suggestion. The big energy companies greenwash themselves, like to greenwash themselves to get some money. And we will show through four criteria that look behind the curtain and show you what are these companies and are they really doing the best for the planet and for the energy energy vendor. Four criteria, the first criteria of this is number one, the company only deals with green energy. This is a very important criteria, because a tariff that is called ECO-tariff doesn't mean that the company actually only sells green energy. So, that is the number one criteria, in which companies only deal with ECO-Energie. So, our first research question was, which ECO-Energie-Companies only deal with 100% green energy? Well, we were a bit naive, so we went to the Bundesnetzagentur. They have a list. It's not a list of companies for that deal energy, but companies that produce energies. It's the same. It's 820 companies and it's a PDF. It's a table in PDF form. However, it just contains the company name and the address. There's no information whatsoever, what kind of tariff they might have. So, we researched further. We found another report from the BNA. Again, it's a PDF. It has several graphs. So, yes, good news, where there's a graph and there must be data. However, it wasn't quite clear. How does the graph and the market relate? I mean, what does that mean for a specific company? So, we send companies, we send emails. Can we get the actual data? The first answer was no. We didn't think that was very cool. So, then we became a little more formal. Well, and saying, well, we actually have a right to these data. So, please hand over the data. And so, they looked at the data again and said, actually, our data are not fit to draw any conclusions at the level of a single company. But we think that would be a good thing. Okay, so, and next year, we will have data that will actually, we can draw conclusions on the level of a supplier. The Umweltswundesamt actually has a market analysis for eco-energy, where they talk about where does the energy come from, what systems are used. This is a rabbit hole, if you look at it. Again, it's a PDF. Nice, lots of nice colorful graphics. We asked for the data behind the graphics. Well, the answer was, actually, the data were done by an external company. They own the data. We just have the license for this one single report. That is not so funny. If you think about it, that we can't get at the data. I mean, we could have bought the data, but we didn't want to do that. So, what we did next is, we scraped the data from everything that we could get hold of. Starting from the B&A lists, from several comparison portals, from lists of eco-labels and best of lists in general. Just to see how can we get as complete as possible a picture. This wasn't easy. There was a lot of manual work, manual labor involved to match names and such, because of course they're written differently and then there's so many different abbreviations. But then we hit it lucky and found the supplier of eco-energy called Lichtblick. The same problem as we did. They too tried to collate such a list and fell back to a manual gathering of data. So, they didn't like the fact that the EEG, the Terfs for Green Power, can be used to essentially greenwash your company. So, they recalculated the data to account for that fact, which is exactly what we wanted as well. We sent a couple of emails. We were allowed to use their lists to check our lists. We unfortunately weren't allowed to actually use their lists. They weren't really familiar with the concept of open data. Tough topic. So, here's a teaser. Our list has 1,210 suppliers. The first 1061 suppliers fail the first of the four criteria because they sell also energy made from non-green sources, gray sources. Only 149 suppliers make the second round. This is a teaser. And actually, this is the end of my talk. And I'm at the end already because we'll be back in January 2020 with another report from Robin Wood. Period. Thank you very much. Thank you very much. This is great. And you've even stayed within timing. Yes, we're all very surprised. Well, you were fast enough. Well, dear translators, you've been warned. And yes, it was fast. So, the S-Nauts. Can we... If you look at this, do you have any associations? Yes, great. Okay, well, let it stand there. So, please hit enter again. Okay, the tension mounts and the tension mounts. Okay, so. Technology can, especially in the energy sector, help to reach our climate goals or just so, or maybe help that isn't entirely bleak. We still need to think. Everything that we think isn't quite as bad will be twice as bad for those in the Global South. So we really, really, really need to speed up. In the energy sector, you see that digitalization has many different aspects. Technology can be used for sustainability goals. But the technology itself also needs energy and resources. And also, that technology needs to be sustainable as well. Where does all this come from? Where is it produced? What are the consequences? So everything needs to be not just ecological, but also looked at under social aspects. How can we make these technologies social and sustainable? So, let's look at digitalization and the crisis of climate and of social and how they feed on each other. And for this we hear Anja Hüffner. The fairy tale of the dematerialization of through technical tools. A warm welcome for Anja. Hello. You had the wish we prepared something for you. Anja is part of the think tank, a new economy. And you are part of the organisers behind the bits and boimers congress. And in your think tank you think a lot about implications of digitalization and sustainability. And you co-author and editor of the book of the conference from the speakers of the bits and boimers congress. And you can download it this book. And it's a great source of knowledge. You have had a talk today already. It's the degrowth talk that was two hours ago. The topic Anja works on and also on the camp Anja told us about the thing. So we have here Greeny who we invited to the tech people and so you are invited for our Sporangium. 2, 3, 1, Sporangium. It's cozy here. We will read a fairy tale from the brothers Gaffam. She takes on her glasses. Okay, so we start with a fairy tale. Once upon a time there was a country where resources were scarce and it changed. In March it became really warm and in winter there was no snow. The king of the country knew that there was a consequence of the too high lifestyle of the people. But he knew that if he would challenge his lifestyle there was a big riots. So he knew that and he had ideas on how to change it. So first one guy said we want to put all the books away and do it through ebooks. And it's easy. Books have to be printed but ebooks work all the time. It showed that the ebook reader took more energy because statistically it was above 50 ebooks that it really worked the ebooks. Then the ebook reader ran out of battery and they had to buy a new ebook reader. So the next business person had a new idea. It's about if we don't print them on CDs but instead we stream them from the internet. It's easy, it's simple. That's very cool, the king said. So everybody streamed in the whole country. A lot of servers were built. A lot of server farms were built. So the streaming was so easy that the people watched more movies in the country. And suddenly at some time the big thinkers thought well it took much more CO2 than before because it took a lot of CO2. They didn't only stream movies or series but also they streamed movies they didn't need. Many of these server farms were powered by cold energy. So the king said well this is not a good idea and he got really mad. So the other businessman didn't work so well said one businessman. But now I have the idea which works really great. When people go out they often leave the lights on. When a lot of people do that then it's a lot of energy. How about we do it with a smart home? So everything is in a network with everything and then my phone knows that it has to switch off the light. And the king said yes, that's a good idea. In the beginning the idea seemed to work. But the businessman forgot that it took so much energy for all the technology and so the energy consumption raise. So he went to the fourth businessman. What should we do? The fourth businessman was a little bit nervous but he took his idea. Don't you think that there's way too much cars on the streets? So, we should have less cars and less time. How about we put automated cars on the street and then the machines don't make mistakes so this is much easier and even if we share it then in the end there is much less cars. So the problem was that people didn't want their cars because it's my car, my Netflix account and so on. The automated vehicles also used a lot of energy and a lot of data. In one minute it used 3 gigabytes so now I didn't need serverparks not only for streaming but also for cars. Everywhere there was a really fast internet even in the farthest corner away it was needed to have this thing. If nobody was helping who should the king ask and so there was a fifth businessman to ask. The fifth businessman said well now I can give my big idea. My how about we solve all problems with one way. How about we optimize all the technologies and all the devices we had. The lamps, the cars, the servers the streaming everything will be solved in one problem. The king was really a little bit skeptical because he saw everything fail but the businessman was really into his idea. How about we make a big strategy where everybody is into it and feels and believes in this strategy. The king said okay I believe in you. So if we do everything if it's sienta then the electricity went down, the electricity consumption went down but the energy controller came back and said well but for some reason the energy consumption is rising again to exploding levels. They looked at the electricity bill and they were really happy because it was so low. Every of the consultants of the king was really happy that the energy went down and now they saved so much money that they could put a new thing a new light for his son who could soccer play at night. Every consultant of the king had a new thing he bought with a new extra money. The king had the revelation and saw that in his country in a few years ago he saw that in a different country but he didn't see when he talked to the businessman in the end nobody of the business people kept their promise so he banned all the five of them so he decided that all people in the country were broke and there were no better ones there also everybody got an energy budget and they couldn't go over the energy budget so he invested into the public transport the king searched in the whole country more experts to for real solutions and if this king hasn't died in the meantime he still lives on so what's the moral? it's not like a fairy tale thank you thank you do you know what you forgot? you forgot the cat videos so in the next story please we would like to see cat videos here is your air snout in pink next we are going to need you the random buzzer start this and you need to say stop tension mounts okay we have seen how to use technology for green goals that's very important and we think about networks we have seen how how we need to make energy screen and we need to change our habits but what we will be at bits and trees if we stay with this one way road also the techies, we techies have thought about sustainability even though we might have always named it this way so we can bring the green activists into the boat to see things in a new way so when you talk about software it's not just about energy but also other aspects anja will tell you so anja will tell you who will tell us about this Karina Haupt sustainable software development for less exploding rockets Karina please on stage hi Karina nice to see you for those who don't know Karina Karina leads the software engineering task force at the DLR, the German institute in our context she looks at the research how to support researchers to develop sustainable software she's also part of the German research engineers foundation and open source enthusiast we are looking forward to 8 minutes on sustainable software development thank you for you 8 minutes i hope my voice is gonna make it for one and a half days i have not spoken just to be able to give this talk sustainable software development for less exploding rockets i'll tell you in a second sustainable software development is something that many people use but there's no clear definition i am not talking about running our computers on eco energy that's certainly a good idea and also this is not about building our computers from sustainable materials in such a manner that it can be used in a more sustainable manner other people can use that software for example our future self in 3 months so to be able to use software later you need to look at a couple of things i did promise you rockets so here is an example that was tried but failed with sustainability this is ariana 5 1996 it's a well back for the ariana 4 a control computer was built it worked really well ariana 4 flew really well and the decision was we're gonna save some money and resources and use the same software for ariana 5 so this was the virgin flight of ariana 5 magnetospheric satellites should have been shut in the orbit it looked good, the rocket started however soon after a strong course correction was done the rocket took a sharp turn that's not good that actually extremely high forces are exerted in 39 second you had a nice firework or maybe not so nice a very costly firework it was a software bug the problem is that the difference between ariana 5 and 4 is 5 is stronger higher faster 5 had accelerations than ariana 4 which triggered a buffer overflow so people thought that if something goes wrong let's at least dumb diagnostic data so the other piece of the software that interacted with the control computer looked at those values and thought they were normal control values misinterpreted the data the course, deviation and ultimately the explosion this is a nice example for sustainable development well it was tried but if you really want to be sustainable then you need to look at a couple of criteria and meet criteria and develop after criteria and there need to be tests so in software development you have the classical integration tests and components and make sure that they work with each other so they've done that and tested the entire scenario and indeed the same result on the lab bench happened which is the simulated rocket exploded too late now but the benefit is that this really brought some attention to developing complex software and so new versions of that software and new methods need to be brought in what you need to do for software development is to look at different fields requirements management, software architecture change management, design implementation, there needs to be a process for change management and testing of course we just looked at testing release management and automation and dependencies i'm not going to explain all of these because that's going to go way beyond my eight minutes so instead i'll just look at the minimum requirements so please raise your hand if you have written code whatever just a few lines will qualify alright that's a lot so do you pass the minimum criteria code under version control is your code online under version control step two make sure your code is in a shareable state what does that mean so we're talking about code style sorry it's speaking names, it's comments relevant parts using functions and ideally also have a speaking file structure who does all of these okay that's less people, number three add the essential documentation yes i know everybody likes that topic i'm going to be really brief here what i'm talking about is a readme or some do but essentially information is missing like what is the software named, what does it mean what is the software good for, what's the purpose use two or three sentences to describe the purpose how do you install the software, what are dependencies what licenses are brought in through dependencies how do you actually start the software or how can you contribute to the source which of you has a readme that does all or at least most of these things okay we're down to very few of you number four, please add a license file add your license terms without license your code cannot be used in a safe manner because if there's no license it's a gray zone that really only means you have the right sort of code please put the license with it with the open source and that's what you do number five, do a release just because your code is out there but if it's anything beyond a really small script prepare your code, test again does it work, document give a release number and number six, this is in gray because this is mostly for researchers make it possible to cite your code let people know how to cite your code this is important for papers if you are in a scientific author you are measured on insights even though the content should be more relevant if you're interested in this you can look at the following links there's guidelines for software engineering that I co-developed there's the eScience center checklist they also develop such guidelines and have information here in checklists step by step to make your code sustainable now, okay, let's see I promised you guys here is more bonus material the mass polar lander actually failed too it was going to land it put down the landing gear and that was actually interpreted as a vibration the other part of the software interpreted this as we're on ground and the lander was actually still 40 meters above the ground and so it crashed into the ground one group knew that this was going to happen or that could happen, the other didn't and until today we haven't even found the crater that it made thank you very much I see bangs, you're getting structure, very good okay, great I think this thing also got a bit horse, the trumpet thing it was a nice example for science science is knowing why it didn't work afterwards alright, so, thank you and we are going to have a very suspenseful carousel here we can enter now, a tension rising okay we had a view on microcosmos cosmic or mega cosmic about sustainable future and we have learned what sustainability sustainability means for technology and has to mean for technology so, please note, convival technology especially Andrea Fetter has drawn up a matrix for this what sustainable technology can cover and who decides which features and functions a technology should have you can think about it if maybe a survey has any consequences for you but we can't and mustn't forget that sustainability isn't just an ecology thing, but also a social thing a lot of these isn't being implemented is being blocked or is being dragged out we have carbon tax that isn't doing much we have power plants that are running longer whether they have no clue or no vision or they have a proper agenda, we don't know but we don't just want to criticize we want to show what needs to be done and what can be done and bits and trees has sat down and between tech people, development politics and climate experts, we have come to an agreement so it can't be too hard and the parties could follow our lead maybe, would be great our demands are supported by roughly half a million people like BUND the environmental organisation or the chaos computer club oh, some things happening what's going on? stop, we can't have that okay, we're being thrown off the stage demands we have a catalogue of demands that's all great but the problem with this list of demands is, yeah, you read it and it's nice, but you just file it somewhere and this can't go on these are demands that are very important and we can't just for that list of demands, we have to call it a manifesto that we are going to defend that we are going to shout out into the world it's a manifesto with 11 Theses and we're going to keep on about it we're going to shout it, we're going to take it to the heads of people we need to internalize it we need to shout out into the world and this is what we are doing now and this is our manifesto these are the Theses of bits and trees and here we go 3 to 1, Spurangium, I just had to say this alright, we are going to start, first point the common good digitization must serve the common good it shall not primarily pursue just economic growth but it needs to promote social, environmental and development policies and also we must keep peace objectives in mind digitization must contribute to a sustainable transformation of energy transport, agriculture and source policy moreover digitization shall foster human rights climate protection goals as well as the end of hunger and poverty a sustainable digitization relies on meaningful, decent work social justice and sufficient lifestyles woop woop then it goes on, second democratic decisions in democracy democracy democratic decisions are basis of good society digitization must be made more democratic in itself and at the same time support democratic processes instead of countering them it must consistent be geared towards promoting emancipatory potential decentralized participation, open innovation and civil society commitment 3 next one, I don't have to tell you this data protection freedom from manipulation and informational self-determination shall be promoted both nationally and globally as essential prerequisites for free, democratic peaceful and sovereign societies let's go on, the next thing is very important 4 controlling and abolishing monopolies we need to create basic traditions for controlling digital monopolies in order to enable a self-determined digital economy in the north and the global south existing monopolies of operators of commercial platforms must be broken existing monopolies of operators of commercial platforms must be broken for example by imposing mandatory predefined interface for exchange between social media services we can implement this right away 5 obviously political regulation must begin to see knowledge and education about technology and its consequences as part of the public good this has to become an elementary component of public knowledge a critical and emancipatory handling of digital knowledge should be part of digital education including the competent handling of false information and hate speech in digital media we need to be faster, 6 global justice countries of the global south must have the opportunity to develop their own digitisation according to local and national needs the costs and benefits of this shall be shared equally between all societies negative aspects such as inhumane working conditions must not be unilaterally passed onto the global south and in conclusion really fair trade bilateral and multilateral trade agreements must not contain any prohibitions or restrictions regarding taxation open source disclosure or localisation then we need it a bit long we need to be excellent to each other and the problem is if we don't do that then we need to make this mandatory then technology sector must be made to commit to sustainability and must commit to human rights ecological due diligence everything else is just stupid and not on next IT security and software liability bad software has bad consequences therefore we need security liability so the developers are liable for the consequences instead of just looking at the dollar signs now long live software software must be adaptable to individual use and must be fit for long term use as is the case with open source software manufacturers must provide security updates throughout the lifetime of hardware devices and make a variant of source code open source at the end instead of just establishing software locks whoop whoop then 11, that's the last thesis long live hardware electronic devices must be repairable and recyclable we have to eradicate planned obsolescence or build in obsolescence of electronic devices whoop whoop how do we accomplish this? warranty periods must be massively extended manufacturers must offer spare parts repair tools and know how for everyone to keep it permanently available this must go in hand-in-hand with greater financial support for open workshops or repair cafes as well as research and development projects geared to the common good public funding must be granted to open source products exclusively whoop whoop and the problem is that with these demands, of course you're all right this is common sense but tomorrow maybe we won't remember because in reality you're just going to go on as before this is why we're trying to raise awareness for this complex and that's why I'm going to do a really public stand I'm going to break this table now so that you remember this so then we can keep on talking very good so common good whoop whoop long live hardware this was a 70s 80s move but we've moved on, we're doing it differently now that's why we're going to open up a repair cafe now one that's geared toward the common good come on more lasting tables so bye bye don't run away don't run away we're going to need you I think we've lost them that was very very impressive please come back maybe we need to hit the buzzer no protest without the buzzer maybe if you recognize the voice from the one protest or another at Edel's Nightmare and this shows that protesting can be fun and this is why I recommend to you all to go to demonstrations and see if they hear you and you can join in the order link, I love it now we're going to come to your task I'm going to prepare the random generator so if you think it feels right now you're going to hit enter ok, I use this button here ok, tension mounts looks good ok, so what I wanted to say these demands, they're good you don't need to remember them you can look at them at bitsundbäume.org so you understand this Sustainability is the goal and Technology is just one of the tools to get there Technology is just like innovation it's never a goal on its own it's always meant as a tool ok, so our first central demands are rather large and put something like democracy at center to get a more green and democratized future and that's why we'll now listen to how protecting the climate and protecting data privacy match alright, Victor Schlüter data privacy protecting the climate and future, please welcome ok, and these demands you can sign these demands and if you don't do that, you will have to memorize them or at least very effectively talk to them Victor, good to see you on the stage we know Victor from his active times in 2017, he has founded digital freedom and has been active there since so he is from far away where we yesterday you were at Kauers West with his punk band System Absturz System Crush, it's really cool ok, we are infiltrated with fans already and by the way, you can dance the thesis yes, so we've just seen it he works in IT security and studies IT security, Victor this is your floor in 3, 2, 1, Sparangium right I don't need to explain what happened last year, Germany millions of people protested took to the street for climate justice and many more internationally Fridays for Future has changed public debate away from immigration to, oh, there's a climate crisis and if we don't do something, many people will die ok, I think that's great that's a good direction I think we all agree that the last year has been the step in the right direction but the problem is that the climate crisis probably endangers many, many, many species and they will become extinct and on the other hand also Fridays for Future is endangered everything goes on as it has gone on so far because if things continue as they are then in 15 years there will be no mass movement like Fridays for Future, there can be no such mass movement and I'm talking about that now in 2001 two airplanes crashed into World Trade Center as an answer that many western democracies in the US and Germany have built mass surveillance so you can look at surveillance and surveillance of behavior and surveillance of movement and of course that includes information in Germany we have Vorratsdatenspeicherung that means collecting un-deciphered information there are also companies that track and collect all the information that can get help the messenger back doors are in the discussion time and again to be able to actually also survey Cypher to communication and when it comes to movement we have targeted querying of mobile cells and also face detection the problem is that technically you will know which person is when, where so compare that to your mobile phone you can never walk around without your face up with it you cannot get out of this already we have gapless surveillance of movement and behavior in Germany but if you predict that in the future for 15 years then it's very possible that in 15 years completely all movement all behavior will be tracked and that will be a problem if you want to protest without leaving a data trace then because anytime I protest I will have to do some behavior I will have to move to a street I will have to be where the protest is if it's not possible to protest without leaving a data trace then the problem is that social mass movements as we know them are not possible a social mass movement if you want to participate in it and it's not possible without leaving that data trace then every time you do that you need to ask yourself can I do this in all future I might be confronted with my actions I might be queried about being at the demonstration I'm gonna look at you differently now maybe this person wants to become an employee of the state maybe they want a specific health insurance maybe they need a specific job maybe it's really important to never be on a list from the police so you never know which political system we will have in the future so that is an incalculable risk so every person will need to understand whether they can afford that also mass protests usually look like this there are small groups that are really really into the topic and larger sets of people that wouldn't take that support the topic but don't take great risks like the school children that took part in the eco-protests sounds funny but we've had that in Germany that if you've been at demonstrations you had to that was detrimental to you that was in the 70s when you wanted to be an employee of the state you were being background checked by the Professor Schutz and if you were too close to the 68 protests you would not be able to enter public service frontline defenders in the last year 200 or 300 so the problem is that if it's not possible anymore to have social mass movements that is a giant problem for your democracy to actually evolve and to get new ideas find a new consensus that's not just abstract for our democracy we need to do this here and now and we need to do this for the climate crisis because I think it's our best chance to actually change anything for the climate and to do something for the climate crisis if you ask people in campaigning they always say you need a crisis to mobilize people to mobilize them you need to show them you need to do something now you can't wait until next month it needs to be now and the climate movement is pretty good at that now they say you need to take to the streets now you can't wait in 15 years mit Data Privacy we're not quite as good because these conflicts are further ahead in the future and we're not able to teach people that we also need to take the streets now for Data Privacy I think we can use the same methods we need go to the streets now such that in 15 years we still have a chance to protest without Data Privacy In both cases, we now need to become active such that we don't lose something really. What good is a democracy if the climate has collapsed? And on the other hand we need our freedom and the possibility to protest without leaving data to save the climate. And so I think we need to tell the story like this. We need to save the climate, but we also need to save those things that we need to save the climate. And so I think that because mass movements are our best chance to save the movement, we can ask these two things. First, climate justice. Second, we need protests without leaving data traces. And that you can think of in a future movement that says we need to act now such that our future isn't fucked. And of course, after I've said this, so what does all this mean, what are we going to do now? I don't have any recipes. Well, I don't think it wasn't really my idea to put these two topics together. That was a bits and trees idea, but I still have some asks of you. So please data privacy people. Please come to the next demonstration for data for climate and bring all the people from your hackerspace. Dear climate activists, what we now need is transparency, is being visible in those groups in which you're organized. Talk about protest, being able to protest without leaving a data trace. And why that is important. And most important, come with us to the next anti-surveillance demonstration. And we don't have a lot of time. The climate movement has needed 40 years to establish the arguments. We now have 15 arguments. I'm sure we can do it, but only if we're in it all together. Thank you very much. Thank you very much. Big applause, please. Great. Thank you very much for this bringing together of movements. And I always take as a good movement to take other people to demonstrations. Specifically, if it makes new friendships. Okay, we're going to get to the next carousel, to the next, okay, we're hitting the enter button now. And again, the tension mounts. All right, okay. Let's all organize majorities, as we do in a democracy, to be able to influence politics. We want to be able to do that, make political transparent, just to reach these goals that we just heard. We only have this one chance. I think it's important to remember what we heard in the first talk. The climate won't be safe for us. And for many it is too late already. The only thing is we can limit the damage now. But how do we do this together? That's not so easy if so. Different people with different backgrounds and different understandings want to collaborate. It needs discipline. It needs possibilities. It needs the right framework. So you can ask how do hackers and eco-acquavists, how do they get in the same space? Is that even possible? So, is there anything between black hoodies and white eco-activists? Where is our common ground? How does our common language sound like? How can we make sure that the barriers aren't too high to be able to look across the fence? So that's why we now look at, Julia, we'll talk about a room for knowledge, where we meet to save the world. Thank you, Julia. Thank you very much. Julia, I'm very happy that you're here today. I am as well. You've studied Germanistical Sociology and now you're finished. You did that in Gina and Osnabrück and now you've done your master's as well to function and legitimacy of female hackerspaces. Julia is interested. She did this at the chaos West stage on day one. It's a very enjoyable talk so you can see in the Internet. You also round a lot for open knowledge, open data. You're a volunteer at Youth Hacks and you're at the chaos meeting of Osnabrück as well. You're also at the Digital Courage University Group. So, of course, you're predestinated to help us understand how we can work together in spaces and hack our future together. So now I'm saying, and I want to hear all of you here, three, two, one, Sparendium. Thank you very much. I'll start immediately. At first, I brought this, a title and a citation. It's called, Who Does Who Makes Is Right. This is a saying you think. Well, it's something that a lot of activists say, that in a lot of activist contexts doesn't matter if here or in the climate activist context. Well, doing things is what makes a difference and it's what actually works. A lot of people talk, but when you start doing something, it's what changes something. Last week, I gave in my sociology thesis, my master thesis and we worked on the topic, how does this society actually work? You learn to question everything, to question everything that humans actually did in this society and the structures. And then I look at this quote and I ask myself, well, who does who makes is right, but who is able to do, to make? Well, this depends on who has the possibility and has the tools to actually do or to make. It's one of the most essential things and one of the most essential things is actually knowledge. So I'd like to add, who knows, can do, can make and is right. I'll admit, some things are missing here. When I do something, something has to happen, right? So first I have to change a part of the world so that something is visible, something is seen. So first I have to create reality. So who knows, can do, can make, can create reality and therefore is right. At least as no one else doubts this and questions this. So now the question is, well, who has the knowledge here in this room? I think there's a lot of people who have a lot of knowledge and have a lot of ideas about sustainability and ecology, who I've seen on the stage. And there's a lot of people who have a lot of ideas of technology and are available in this topic. But where can these people come together to share this knowledge and can become active together and save the world? That would be a good plan, I think. So of course now I have a special view on the meeting point between technology and ecology and I've asked myself, where's the space for knowledge? So I'm thinking about, well, I myself, you've heard it. I've studied Germanistic and Sociology. It's pretty far away from topics about technology. Who else is in this topic of more technology distant realms? Well, it's not so many people. Well, now I'm going to confront you with shocking reality at first. How important is knowledge? Well, I'll give you an example. I did an internship. I had to work with an Excel sheet with 3,000 Tables. And now I had to work with these columns and change them and that was a stupid job for me because I could automate this job. But my chef actually didn't know this. So, well, knowledge is a tool to make jobs easier. A different example was at the Hackathon. A politician in the jury was very surprised. What? You can actually encrypt without blockchain? Well, yes, it's possible. So knowledge also is an orientation, of course, because in the media, if you always am here, there's always a connection between cryptocurrencies and blockchain on the other side, then you always think it's the same thing and it's also important for encrypting, but it's actually not. So, if there's a lack of knowledge, or let's say the other way around, when there is knowledge, we notice this when we talk with each other and we talk with each other in spaces. Well, mostly sometimes also more on their cell phone in virtual spaces where we communicate with each other. But still, if we want to meet, if we want to convene, to find out who has which knowledge, who can share the knowledge, then it's obvious that knowledge has already to be there so that you can join, so that you can create together. So, the question is, what do we actually need so that communication between different peoples is possible, as well as in the virtual, as also in the real world. So, number one, we need usable software for one, that's our first idea. Usable, of course, is one of the part of this word. You can press it and it actually works, but it also means you have to be able to put it together with the idea of democracy. So, do I want to use this in the idea of democracy? And a lot of times in the communication devices of big US American companies, I'm not sure if I really want to use it in a democracy, so that's also a question of, what do I want to use, not only what can I use, and that also excludes some people. Number two, we have to share our knowledge so that we can reach something together. This also includes not only the knowledge that, but also the knowledge how to do this. I know that encrypted communication is possible and that a private key should be private, but in the end I might put it in a chat accidentally, oopsie, sorry. So, it's also important to see how does encrypting, for example, or how do things in general work, because we have a big problem, it's called digital divide. It's a big societal divide between the people who have knowledge and the people who do not have knowledge, between the people who have access to the internet and those who do not have access to the internet. That actually means knowledge is costly. Not everybody has the access to this knowledge. Not everybody has the time to research, but everybody has the money to research, has the possibility to research all of this knowledge. So, yes, knowledge is costly. And the third point, we can only work together if we share resources. When we split the costs, well, we say you may not have time because you have to cook. So, okay, you can cook and we will do other things. We have to actually share the abilities and the resources that we have. So, if we want to change the world together, we have to create spaces where we can actually do this. And these actually exist. These are hackspaces. These are places where we share researches and knowledge. And that's what I was looking at in my master's thesis. To find out, okay, so why, how can we reach accessibility? Accessibility, another point that's important. On the one side, design and language, because of course it's great if all of us walk around with hoodies and stickers and we have a certain image of ourselves and it gives us identification. So, in this time for others, this can seem exclusive. It's the same thing with language. Of course, abbreviations are clear to us, but not always to others. That means that a space is always dependent on how we construct it with our actions. That's what we call social construction. So, it means it depends on how do I understand a different person and if we understand the person as a woman, for an example. So, who's girlfriend are you? It really gets the person's nerves. So, spaces are constructed socially. And if we all want to save the world together, then we should really think about these kind of things. Participation needs to actually work together, needs the knowledge and to have the knowledge means you have to have accessibility. So, developers, please make good software that's usable for everybody. Cities, please give us the spaces, or at least leave us those that we have. And people, please live up to your values. Because if we want to have accessibility, then you have to create it. Think about your actions, think about how you create spaces. If you want to save the world, then please look, what is sustainable? And if you really want to live freedom, then for God's sakes, encrypt your data and show others how to do it. Thank you very much. Thank you very much. And this applause shows that a lot of people are on your side, hopefully. Yeah, now you may sit down in a second. And where are our ass-nuts? Here's your ass-nuts. Ah, thank you. I know you've been looking forward to this. All right. Now we're going to play the same game with you. We are going to start a random generator, who is obviously totally smart and who knows who's left. But please, press enter, yes. Tension is rising. Who is still on our list? Now we have seen how we can communicate, how we can organize majorities, what we have to pay attention for and what we have to pay attention for when we're doing protests so we can take everybody along. We have seen how important transparency is in sharing information, in questioning things and how to change politics and society according to these societies together. And we only have this one chance. But how does this all work together? You've told us. And so far we have talked about the now, the here and now, how we are going to design our togetherness. And now we're going to look at the future. So we're going back to the rockets that we've mentioned and we're going to go on a journey to the stars. Now please read out our last talk. Isabella Herrmann, Utopia Outer Space, the future of humanity in science fiction movies. Welcome Isabella. Please take a seat. Hello and welcome. Isabella, nice to have you. We're going to hear about Utopia Outer Space, the future of humanity in science fiction movies. She's a political scientist and science fiction fan. And she combines these two interests by examining which sociopolitical values are present in science fiction movies. We're all into science fictions, or at least most of us. And there's not just neutral statements. But technology shows a lot about our societies. Also, she's a festival associate of the yearly Berlin Sci-Fi Film Festival. It's going to happen again next November. Yeah, it's in Berlin, so of course it's in Berlin. Oh, you're all invited. So, you have eight minutes now and have fun in three, two, one, Spirandium. Hi, I'm going to take you away at this late midnight hour. I'm going to take you to outer space. And I want to show you what science fiction, the genre of the future, can show us about our future in outer space. Maybe one of you has already realized it. This is a picture from Interstellar, the protagonist and his daughter looking at the stars with great hopes for the future. Now, the question is why do people want or have to in movies like Interstellar leave Earth and we can look at the motto of this year's Congress, resource exhaustion. It's simply a fact that us humans are ruthlessly exploiting nature and so life on Earth has become impossible. So, it's always about the very current topics and it's being extrapolated into space and into the future. Now, the question is, can these science fiction films like Interstellar, where everything has gone wrong already, can they tell us something about how to maybe do it better in the future? So, if us humans, if we can see us more as part of the ecosystem or if we should maybe invest more into technology. These are the questions. And there it is. And now we're going to gallop through science fiction movies, four movies in four minutes. So, maybe we can finance us through these questions and who would have thought, I'm going to start with Interstellar. And Interstellar isn't set in 2014. It is set 30 years into the future, mid of the 21st century. And in Interstellar, humanity is plagued by sandstorms. Agriculture is down. This can't continue. And therefore, a mission to space started to find a habitable planet somewhere in outer space. And this mission is successful. We, the audience, don't get to see this planet, but we get to see a space habitat on the way there. And if this space habitat is real or just a delusion of the protagonist, that doesn't matter. What is important is that in this space station, in this habitat, we see the ultimate tech fix that makes nature a perfect product of humanity. And what do you pick? Of course, you see a thoroughly cultivated piece of the USA, where everything is ordered neatly. You have neat fields and they curve upwards like an inception. The same director, of course. And you get an idea of how it might look on these other planets. It's ominous, but maybe you can look for another planet. So let's just continue on as we have done before. And we're doing as before in cargo. It's a bit farther in the future, in the 23rd century. And Earth has become inhabitable. And as you can see on the right, you can live in a space station that is like a Blade Runner. It's inhuman, it's cold and inhospitable. And the only hope humanity has is going to Rio. Rio is marketed as a geo-engineered planet and it is habitable and it is fertile. So you can walk around in nice dresses, in fertile Fields, it's all really very great. And if you haven't watched the movie yet, spoiler alert, please close your ears now. Rio is just a simulation. And if you buy a ticket to get flown to Rio via a space shuttle, you are going to cry asleep and you are being locked into the simulation. It's a great example for the ultimate tech fix where all the possibilities are available. But we choose a picture of nature that is again available to nature to exploit at will. At the end of the movie, we realize that Earth is fertile again. And what do we do? We send volunteers to Earth to start a new agricultural production. So history repeating itself. There's also similarities to the film WALL-E. It's set very far in the future, 29th century. And the Earth has become inhabitable and littered with garbage. And the poor cute robot WALL-E has clear about shit. Humans are living on a space station. They're doing well. But they're all degenerates mentally and physically. WALL-E finds this tiny plant and automatism is triggered that humanity can return to Earth. So as soon as nature has fixed itself even a little bit, we have to go back. And another direction moves the film The Martian. The starting point is in the year 2035. There's no ecological collapse. But there's just a space mission. And some unfortunate circumstances. And the protagonist is stranded on Mars and has to fend for himself. And has to work for his own survival. What I think is very interesting is the title The Martian. Because he doesn't become a Martian. He doesn't adapt to Mars. It's the other way around. He stays a human from Earth and adapts Mars to his needs. And the question is that we have to ask ourselves, can we do it differently? Can we conceive a different idea of humanity? And now we need to diverge a little bit from our path and all these Mars and space movies. A part of a broader discourse space where it's about fictional and real stories. So that we really need to go colonize Mars. And there's Elon Musk and SpaceX. And he's arriving force behind this. And if he could, he would probably fly his Tesla to Mars. But that's another talk altogether. Okay, so what has this quick journey taught us? What has it showed us? It has shows that these movies, whether they play in space or back on Earth, there are no real solutions there. Rather, they go back to the same old story. And we can see this critically, because films that pretend to talk about the future, but they reinforce the status quo. I wouldn't be quite this critical. I think generally, just as well as the media scientists here, it's not the job of science fiction to show us how to solve problems or how to avoid problems. How should they? It's more a fact that they state that our society has concrete problems, anxieties and questions. And the films that I've showed you are an offer to get talking about the future. And so I think that science fiction is as fascinating as it is. Well, live long and prosper basically. Thank you for this conclusion. Thank you. So please sit down for just a second. Here you have your air snout. So can please have some spacey feelings on the stage now. So no light please. Please take out the black light. Sprangium, Greek engine, vessel. An almost spherical container of people in which the ideas are created. In most cases, Sparangium has a special mechanism in order to spread the knowledge over great distances as possible. Sparangium of the 36th Kias Communication Congress around the spark containers of the CCC speakers curls a row of neurons with a strong inner walls and thin outer walls. Initially the cells are filled with space, but as the knowledge matures on stage, they gradually fill up. The pressure inside the cells changes due to this process. When a critical value is reached, a phenomenon occurs called cavitation through the formation of knowledge inside the cells. The cells expand. The strong inner walls now act like a spring under tension. They bend the cell row in the opposite direction. The catapult is loaded. Now the knowledge is thrown out of the spark capsule at high speed where the spirals fall on fertile soil. New ideas can thrive. This was bits and trees at the 36th Kias Communication Congress. Your translators were Gooniesbro, The Snakey and Mareike. So, we thank all our presenters here. And we also thank our number guy. And thanks to our interpreters in the cabins. And thanks to the Vok. Thanks to all helping angels like Whale, who supported us and has organized everything we have needed. And thank you. Big round of applause for all of them. This is for you. Thank you, the content team, for the courage to let us here onto the stage. And maybe for our stage to let the masks onto the stage. And a huge thanks to my dear friend Marco from SPRI for the design and the colorful existence here and to be our emergency hotline if we needed. New slides in a hurry on if the video was broken. So, thank you very much for that. And this is your applause, please. Come on, stand up. And in conclusion, let's just mention to the right bottom, together we can make it. But if you remember, we have to make it together. So, thank you all. If you have, come on, proper round of applause.
