Es wird um die tollen Drohnenprojekte der Kölner Community gehen. Es steht auch Material zum Ansehen oder zur Einblendung zur Verfügung. Wir zeigen, welche Möglichkeiten sich durch den Einsatz von Drohnenflügen für die Wikimedia-Projekte ergeben und wie Wikimedia-Deutschland die Ehrenamtlichen dabei unterstützen kann. about this event: https://cfp.verschwoerhaus.de/rc3-2020/talk/PF83SX/

Every day, surveillance companies attack mobile networks, attempting to track the location of mobile phone users. We will analyze, using real-life data, these surveillance companies’ tactics and show the different ways that users are tracked in the wild over 2G, 3G and 4G networks. For 5G, we describe the critical functions and information elements in the core network that might be targeted by these attackers. Mobile core signaling networks have been known to have exploitable vulnerabilities for several years. However very little information has been presented on whether these vulnerabilities are being exploited in real-life or not, and if so, how it is being done. This presentation will give first-hand information about how location tracking – the most common form of mobile signaling attack - is being done over multiple types of mobile networks in the wild today. We will start with briefly introducing mobile telecom networks, their known security flaws and how surveillance companies exploit these flaws. Surveillance companies are success oriented and have a toolbox which they use for location tracking of mobile phone users, which is the most common attack. Based on real-life experiences we will describe what “tools” we see in the wild and how they work. We will also describe how attackers optimize attacks based on the target network and technology, and how attacks have changed over time since some mobile operators have begun to put in place protections. We will also show a visualization of how these attacks can happen. Finally, we will make a projection for 5G core networks, and how they will also be targeted by surveillance companies as they are deployed globally over the next few years. about this event: https://fahrplan.events.ccc.de/rc3/2020/Fahrplan/events/11511.html

This lecture will highlight commonalities and differences of the climate crisis and the Covid-19 pandemic. Both crises are symptoms of dysfunctional unsustainable interactions of social systems with natural systems. In this lecture I will unpack the common elements of these crises and outline lessons learned from the comparison. Building upon a recently published scientific article, the analysis is divided into four sections: diagnosis, prognosis, therapy and rehabilitation. It highlights the role of science in its ability to anticipate crises before they are imminent, for example through projections and probability calculations. The climate emergency and the Covid-19 pandemic are characterized by critical time points, after which certain damages (such as loss of life) can no longer be avoided through adaptation measures. This time criticality does not allow us to wait for the perfect solution. Therefore, early preventative action with available measures is of the essence. Collective action guided by courageous moral stewardship on different levels of governance is key to overcome these complex crises. In closing I will thus discuss our understanding of the differential responsibilities across generations and income groups to contribute to transformative solutions. about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/NCZR93/

None Die seit Jahren anhaltende Trockenheit zieht vor allem Bäume in starke Mitleidenschaft. Zwar werden frisch gepflanzte Stadt-Bäume von der Stadt die ersten Jahre noch gegossen, doch dieser Bemühungen, gehen viele Bäume leer aus. So hat das CityLab Berlin die Anwendung giessdenkiez.de entwickelt, die Bürger informiert und motiviert, selbst Bäum in ihrem Kiez zu adoptieren und regelmäßig zu gießen. Auch wenn auf Berlin beschränkt, gewann die Anwendung auch über diese Grenzen hinaus Bekanntheit. So wurde an das OKLab Leipzig der Wunsch herangetragen, diese Plattform auch für Leipzig aufzusetzen. Neben den interessanten technischen Herausforderungen dieses "Redeployments" (und der damit vermiedenen Neuentwicklung, auch Dank der Unterstützung des CityLabs bei Fragen) sind die dabei und daraus entstandenen Kontakte und Kooperationen mit regionalen Akteuren (Stiftung Ecken Wecken mit ihrem Lösungsteam "Baumfreundschaft - Gießen im Quartier", dem Amt für Stadtgrün, BUND, NABU, Oekoloewe, Umweltforschungszentrum (UFZ), Parteien im Stadtrat) berichtenswert. Zu dem die Bedeutung von OpenData, sowohl die Baumkataster-Daten der Stadt, als auch die Niederschlagsdaten vom Deutschen Wetterdienst (DWD), ohne welche diese Anwendung nicht möglich gewesen wäre und nun sogar die Offenlegung weiterer Daten fördert.

What are social imaginaries, and why are they so relevant for understanding current times? In this session, we’ll dig deep into this question while we also get our hands dirty in a meme making workshop where we’ll try to envision how the imaginaries of 2077 might look like. Let’s design metamodern narratives, but make it fun and funky. **REGISTER TO ATTEND** https://us02web.zoom.us/meeting/register/tZUscuiopj8sHtO-cL7tELcyd5GBXYF7EPrT After registering, you will receive a confirmation email containing information about joining the meeting. about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/DMACWJ/

We have started building the CCC Camp in unity as a game mod for a hacking game called OffGrid. We have build the rough camp site, milliways and most of geraffel and the c-base village. We would like to extend this to more if not all of the camp site and create a digital walkable memorial of the ccc camp 2019. We will be using the rc3 to work on this map mod. This workshop is for anyone who wants to come and learn how to mod 'Off Grid' - a hacking game about surveillance and data privacy - and make their own levels and hacks. Come and hack the game with us! An inside look at how Lua moddable videogame 'Off Grid', which is currently in development, can be used by modders and hackers to explore hacks and vunerable devices, and to open up hacker culture and infosec stories to future hackers, both young and old! We'll be going over how to use our LevelKit to build levels and how to mod or create your own Lua scripts to make your own righteous hacks, devices with abhorrent vulnerabilities, or data types that will alter space-time. Come with a laptop and some unique hacking ideas and we will help you with the rest. No previous knowledge of Lua or game development required :D Your machine will need to be able to run Unity engine, (https://unity3d.com/unity/system-requirements) - Windows is the most stable platform, there is a beta version of the Linux Unity editor available but it does have some issues (hence not RC yet) so worth bearing in mind. Before attending if you could download Unity version XXXX that would be great (https://store.unity.com/download?ref=personal) Also having Steam installed would be a boon, as this is the easiest way for us to distribute the tools. (http://store.steampowered.com/about/) But if you aren’t keen on the platform we will be able to pass you the files directly, you will just have to download some files from the internet. :) Videogames have a culture of being a unique medium for exploring complex systems and ideas. 'Off Grid' is a third person stealth / hacking game which forgoes weapons for hacking tools and ingenuity, and it is completely moddable. The idea being that players, modders and hackers (many of whom caught the hacking bug by messing around with games in the first place) will be able to use the game to tell new and interesting stories about hacking and surveillance, create new hacking tools in the game, and who knows even drop a 0day or two for real... Expanding on a talk given at Electromagnetic Fields camp in the past, Rich will give a live demo and talk you through Off Grid, and show how the moddable API he and his co-devs have been developing means that players and modders can not only use Lua to build new levels but also their own hacks, hacking tools, data types and vulnerable IoT devices. Although the visualisation is an abstraction of hacking, all the underlying principles are made to reflect real live circumvention tech and hacking tools. mc.fly will walk you through the ccc camp 2019 mod and explain how to design and add your village to it. about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/ZL7BAV/

Oftentimes, we read about the state of digital rights on the Global North and their challenges, but we hear little from the Global South. What is, then, the state of digital rights on the Global South and, specially, in Latin America? Are those rights threatened in the same way that they are in the Global North? Do those rights apply in the same way? On this talk, we will explore these questions. We will touch upon the history of digital censorship in Latin America, how it has evolved, and how surveillance in the region is increasing. Perhaps one of the biggest challenges that we have as a community is the fact that we hear little from the perspectives from other regions of the world that are often consuming the technology and ideas produced from the Global North. This talk will aim to bring the Latin American perspective to the table: to talk about the state of digital rights in the region, about the challenges facing towards a digital sovereignty, about the state of digital rights from a legal and political perspective, and more. about this event: https://fahrplan.events.ccc.de/rc3/2020/Fahrplan/events/11526.html

CO2, Kohlenstoffdioxid, ist inzwischen im Bewusstsein aller angekommen. Ob als ppm Wert in der Erdatmosphäre und als Treibhausgas, oder durch die im Sommer vorgeschlagenen CO2 Ampeln. Aber: wie kann man denn die Konzentration eines unsichtbaren Gases in geriger Konzentration messen? Die "CO2-Ampel" hat seit August sprunghaft an Bekanntheit gewonnen, als die Konzentration von Kohlendioxid als potentieller Indikator für unzureichenden Austausch der Raumluft und damit für ein generell erhöhtes Infektionsrisiko vorgeschlagen wurde. Die prominenteste Sensorfamilie arbeitet über die Detektion der breitbandigen IR-Absorption des CO2-Moleküls, wir sehen uns IR- und Rama Spektroskopie an, wie einfache Sensoren funktionieren bis hoch zu hoch genauen industriellen Sensoren. Eine weitere Detektionsmethode bieten Metalloxid Sensoren, die mit moderner MEMS-Technologie sehr kompakt gefertigt werden können und mit der Größe eines Streichholzkopfes gut geeignet für wearable Devices sind. Dabei unterscheiden sich Sensoren, die tatsächlich CO2 messen können von solchen, die flüchtige organische Verbindungen (engl. volatile organic compounds, VOC) messen. Ein VOC Sensor findet sich auch auf der auf dem Camp 2019 vorgestellten card10 smartwatch. Wer eine besitzt, darf gern die neueste Firmware installieren und zu Hause mit experimentieren! about this event: https://fahrplan.events.ccc.de/rc3/2020/Fahrplan/events/11550.html

Die Geschichte einer Kollektivkneipe, das Aufdecken eines Briefkastenimperiums und eine Räumung. Und was das Ganze mit Birnenschnaps zu tun hat. In meinem Vortrag werde ich das Syndikat und seine fast 35-jährige Geschichte vorstellen und was es heißt, als Kollektiv ohne Hierarchien zu arbeiten. Der Schwerpunkt wird auf der Kündigung durch den sogenannten Eigentümer "Firman Properties S.a.r.L." im Jahr 2018, unserer Recherche zu dieser Briefkastenfirma, dem Aufdecken des dahinter stehenden Immobilienimperiums (Pears Global Real Estate mit Sitz in London) und den vielfältigen Protesten und Aktionen gegen dieses Immobiliennetzwerk liegen. Außerdem gebe ich einen Einblick in die (internationale) Medienresonanz und unsere Vernetzung mit anderen bedrohten Projekten und stadtpolitischen Initiativen. Abschließend werde ich auf die unverhältnismäßige Räumung des Syndikat durch über 2274 Polizisten, die damit verbundenen Einschränkungen der Versammlungs- und Bewegungsfreiheit sowie den Gegenprotest berichten. Das Syndikat bestand seit 1985 als Kollektivkneipe und war für alle Leute aus dem Kiez und darüber hinaus (außer Nazis, Antisemiten, Sexisten u.ä.) ein Anlaufpunkt und Ort des sozialen Lebens, der Solidarität, des Austausches und der Vernetzung. Hier kamen die unterschiedlichsten Menschen, Ideen und Initiativen zusammen. Darüber hinaus haben wir mit Solipartys und unseren Trinkgeldern immer Projekte aus den verschiedensten Spektren unterstützt. Von Repression Betroffene, ein Kinderheim in Sri Lanka, Kiezinitiativen, Mieter:innen, Geflüchtete, progressive politische Gruppen in aller Welt, um nur einige zu nennen. Die Kneipe war ein soziales Netzwerk, wenn auch offline. about this event: https://talks.rc3.oio.social/r3c-oio/talk/9ZDC9X/

What kind of cyber-physical infrastructure can insure that producing for human need can stay within planetary boundaries? This is based on the recent P2P Foundation report, 'P2P Accounting for Planetary Survival', which you can find here: http://commonstransition.org/p2p-accounting-for-planetary-survival/ Kate Raworth's Doughnut Economy proposes an economy that can navigate below an ecological roof, that preserves planetary boundaries, and a social basement, which insures the basic needs of humanity. In our study we looked at three inter-related emergences of shared accounting and distributed ledgers (contributory, flow, and thermodynamic), and the possibility of a 3-layered cyber-physical infrastructure that combines the best of the commons (open stigmergic collaboration), of generative markets (that integrate externalities) and orchestrated planning limits to protect resource constraints. about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/QEFPZX/

Seit der Wahl Donald Trumps 2016 erleben wir einen offensichtlichen Niedergang der liberalen Gesellschaftsordnungen in zahlreichen Ländern innerhalb und außerhalb Europas. Die weltweite Zahl der Staaten die als Demokratien bezeichnet werden können nimmt dann in den letzten Jahren auch stetig ab. Im Vortrag soll es darum gehen die Ursachen und Konsequenzen des Niedergangs der liberalen Demokratie zu analysieren und mögliche Gegenstrategien aufgezeigt werden. about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/DWZVSZ/

With her transdisciplinary works, media artist Theresa Schubert manages to make the fine connective tissue between human / nature on the one hand and science / technology on the other visible and, above all, tangible. Often, organic materials such as slime moulds, fungi or bacteria are the starting point for an experimental exploration via practices of posthuman self-organisation or interspecies communication. In her lecture, she will present some of her art projects and her methodological approaches - such as biohacking, theoretical analysis or performative interpretation. about this event: https://fahrplan.events.ccc.de/rc3/2020/Fahrplan/events/11416.html

Storing ice volumes of more than 65 meters sea-level equivalent, the ice sheets on Greenland and Antarctica are by far the largest potential source of future sea-level rise. Their long-term stability thus determines the fate of our coastal cities and cultural heritage sites. While massive in size, the ice sheets also belong to the most vulnerable parts of the Earth system: feedbacks between ice, atmosphere and ocean give rise to non-linearities in their response to progressing global warming. Once a critical temperature threshold is crossed, this could lead to self-sustained and potentially irreversible ice loss from drainage basins in Greenland and Antarctica. In this lecture, we will review the processes behind these dynamic instabilities, discuss the potential of crossing ice-sheet tipping points in the future, and explore the resulting impacts on sea-level rise and our global climate – not just for this century, but for the next millennia and beyond. about this event: https://fahrplan.events.ccc.de/rc3/2020/Fahrplan/events/11484.html

The EU Commission is using education politics and digitization to increase European Integration and move beyond ERASMUS+. Current trends in European Higher Education Policy include the European University Initiative, Micro-Credentials, Virtual Exchange, Internationalization at Home or the Student eCard. We want to show you how these ideas and concepts are interconnected and discuss the pros and cons of the current developements as they can lead to more democracy and more cooperation as well as to more isolation. As the common notion of an "ever closer union" has failed with Brexit, new ways are considered to increase Europeanization. Although the idea is as old as the Union itself a new concept has taken center stage promising to create greater cohesion within the union: the European University. In November 2017, the European Commission went public with plans to start a so-called "Sorbonne Process" in order to create an EU-wide common educational area (EEA) in which mutual recognition of qualifications, mobility and improvement of language acquisition are tackled in unison. These efforts include the introduction of European University Alliances (EUAs) and a Student eCard. The latter aims to improve the exchange of bureaucratic information between universities in the EU. Other concepts like Micro-credentials, Virtual Exchange and Internationalization at Home have later been added to these new efforts by the Commission. The EUAs have become important testing fields and launch pads for these ideas and student representatives are increasingly worried about their implications for the future of education. But while these new instruments can fundamentally change the nature of higher education, there are also reasons for optimism. From the beginning on some of the EUAs have included democratic student involvement in all their structures. We hope that these early efforts can lead to new forms of student representation, teaching young students democratic cooperation on a European level and helping them represent their interests even better. This talk will introduce you to current trends in European Higher Education Policy with special attention on how digitization is used to further strategic goals of the EU Commission. The implementation of the European Universities will not be without conflict and conflicting positions: Micro-Credentials, European Student eCards and new democratic structures can lead into a benevolent as well as a malign future. Our talk aims to cover all relevant dimensions and offer you the opportunity to discuss with us the problems at hand. about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/Y7GFRS/

Der Wechsel vom Präsenzunterricht auf Ortsungebundener Unterricht war für viele Schüler*innen und Lehrer*innen eine ziemliche Umstellung - besonders für mich. Als eine gehörlose Person möchte ich näher bringen, wieso der Onlineunterricht über Video-Calls und die Integration bzw. Inklusion zurzeit nicht kooperieren (können) und selbst als Träger von beidseitigen Cochlear-Implantate seit der Maskenpflicht auf mehr Frustration und Ärger im Alltag mit Kommunikation stoße. Barrierefreiheit beginnt mit einem Gespräch. Und dieses Gespräch will ich mit euch führen. about this event: https://cfp.verschwoerhaus.de/rc3-2020/talk/MWMEMT/

Forestry and woodland accounts for just 1% of the land in the West Bank. Accessible forests like Sweitat Garden, close to the cities and regularly served by public transport are even fewer in number. Jenin city is home to around 40,000 people, whilst the broader Jenin region has a population of over 250,000. There is a growing, young population in the area, who lack free, open, safe places to play and roam. There is just one theatre and no wildlife parks, or museums about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/CCHVHL/

I talk about failures of AI/ML, how it more often affects minorities, can even have deadly consequences, what the reason for those failures are and what we can do to prevent this from happening in the future. Nowadays “Artificial Intelligence” is everywhere! And rightly so, it does enable us to do really cool things, things we couldn’t even imagine doing just a decade ago. In fact, it sometimes just feels like magic. This ‘magic’ behind it is often powered by “Machine Learning”. But even “AI” has its limitations. I’ll show examples where “AI” and ML have failed (sometimes with horrible consequences) and will explain why failures are unavoidable in ML but also mention what we can do to reduce them in the future. Furthermore, I’ll showcase how current AI implementations discriminate against minorities and how that in some cases even leads to a higher risk of death for those groups. I’ll cover the bias that humans introduce and I’ll explain how poor choice of data makes our world even more unjust than it already is. The takeaway for the audience: AI can fail and sometimes it has horrible consequences. Why is AI so hard to “do right”? How can we make AI better? about this event: https://pretalx.rc3.studio/rc3-channels-2020/talk/8VFMPP/
