Mit einer Strichfiguren-KI von Fraunhofer sollen die Passanten \"digital skelettiert\" und analysiert werden. Strichfiguren, die sich nicht angepasst und unauffällig verhalten, lösen einen Alarm aus. Allerdings können Umarmungen nicht zuverlässig von Schlägen unterschieden werden. Gerne wüssten wir mehr über die KI, wie sie trainiert worden ist und welche Minderheiten sie besonders gut diskriminiert.\n\nNach einigen IFG-Anfragen, kleinen Anfragen in der Hamburgischen Bürgerschaft, diversen Presseberichten und einer Diskussionsveranstaltung wissen wir noch immer (zu) wenig.

Wie, das erzählen wir euch in unserem Lightning Talk!\n\nEs ist faszinierend mitzuerleben, wie sich die FOSS-Bewegung den Techgiganten tagtäglich mit unglaublich viel Kreativität und tausend tollen Tools entgegenstellt, die unsere persönlichen Daten persönlich sein lassen und uns in immer mehr Bereichen Alternativen zu fancy durchdesignten Apps bieten, die oft mehr shiny sind als nice. \nDennoch bleibt das Wissen über all die tollen Möglichkeiten zum Schutz der eigenen Daten und warum das überhaupt wichtig sein soll, häufig ein intellektuelles Privileg. Und auch Hardcore-Nerds überblicken doch meist nur ihr eigenes kleines Techno-Village und bekommen gar nicht mehr mit, dass Open Source, Fediverse und DDOS-Attacke vielen Menschen einfach gar nichts sagen.\nWir, das @all-Kollektiv, finden, dass sich das dringend ändern muss.

In line with its FLOSS tradition, the University of Innsbruck focuses on the Fediverse and has established an instance on university servers. Alongside insights into the process, motivation and networking is the aim of this Lightning Talk. Universities, join the Fediverse!\n\nThe disaster with Twitter highlighted the risks of relying on commercial platforms for central communication channels. This isn't new, but it sharply illustrates the issues with much of social media's structure. Universities can significantly contribute to establishing the Fediverse as a decentralized, non-commercial, privacy-conscious network. Using the example of the University of Innsbruck, the talk will show how a trio from different departments, science communication, data protection and IT, set up a Fediverse instance for institutional science communication on Mastodon on university servers. This Lightning Talk aims to inform and showcase how one university successfully engaged with the Fediverse, serving as a call to action for other universities to join in seizing the opportunity to improve online communication structures.\nMelanie Bartos, Hansjörg Pehofer, Matthias Weiler","original_language":"eng","persons":["Melanie Bartos"],"tags":["37c3","58016","2023","Science",""],"view_count":314,"promoted":false,"date":"2023-12-29T12:55:00.000+01:00","release_date":"2023-12-30T00:00:00.000+01:00","updated_at":"2026-03-14T22:00:06.809+01:00","length":297,"duration":297,"thumb_url":"https://static.media.ccc.de/media/congress/2023/58016-790bf4f4-e6d1-5271-8460-4049b8ff1c83.jpg","poster_url":"https://static.media.ccc.de/media/congress/2023/58016-790bf4f4-e6d1-5271-8460-4049b8ff1c83_preview.jpg","timeline_url":"https://static.media.ccc.de/media/congress/2023/58016-790bf4f4-e6d1-5271-8460-4049b8ff1c83.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/congress/2023/58016-790bf4f4-e6d1-5271-8460-4049b8ff1c83.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/37c3-lightningtalks-58016-universities-step-into-the-fediverse-reclaiming-digital-sovereignty","url":"https://api.media.ccc.de/public/events/790bf4f4-e6d1-5271-8460-4049b8ff1c83","conference_title":"37C3: Lightning Talks \u0026 Clips","conference_url":"https://api.media.ccc.de/public/conferences/37c3-meta","related":[]},{"guid":"5dbd1227-15b1-52fb-a8eb-b7f0f8bfe93b","title":"Building your own algorithms for social networks - Bluesky Custom Feeds with SkyFeed","subtitle":null,"slug":"37c3-lightningtalks-58023-building-your-own-algorithms-for-social-networks-bluesky-custom-feeds-with-skyfeed","link":"https://pretalx.c3voc.de/37c3-lightningtalks/talk/S3GEE8/","description":"Most social networks use proprietary algorithms to recommend new content and keep you on their platform for as long as possible.

Meanwhile, a litigation in Cyprus and Italy targeted a porn giant for violations of General Data Protection Regulation (GDPR).\n\nWe will present the achievements of our campaign to reshape the sector of online pornography and why this is so important for a better cyberspace for all. The adult entertainment industry was valued at nearly €45 billion in 2022, while major porn platforms today rank among the most visited websites in the world. This is truly a multi-stakeholder landscape and, through a continuous collective work, we have identified many core issues to be addressed. The fight against gender-based violence, the destigmatization of sex work, the accountability of big tech, the empowerment of CSOs and much more are all crucial aspects of our initiatives. We are confident that with a truly holistic approach we will be able to foster positive change. As we expect substantial transformation of the online porn industry in the near future, this is the right time to push together for inclusivity, decentralization and transparency in this field.

For most audiences, this is a choice between two foreign locales. We need to do better. We can choose another English: an International English.\n\nOur choice of language defines the framework for our communication. It defines what’s expressible, and what the defaults are. It limits our expressibility in ways seen and unseen, and subtly hints where our allegiances lie.\n\nIn this post-Brexit Europe, English is a more neutral choice than it’s ever been. We need to recognise this, and to capitalize on this opportunity to appropriate the language wholesale. In the software we write and the sites we maintain, we can: European English and International English are already supported by the underlying standards and libraries, and it’s up to us to use them, and to own our voice.\n\nThe English we speak in international contexts does not need to change; we only need to explicitly realise that it is _our_ language, and that it does not need to bow to imperial authorities. Beyond that, I want to change default language of the Internet.
