You even might have heard names like YC ombinator and a16z\, or terms like "Unicorn"\, "PMF" and "TAM".\n\nBut whe re does that money come from? How can you get it? And why do people contin ue to give money to startups\, despite 90% of them returning 0 money?\n\nE ven among IT nerds\, VC is often seen as something vague and mysterious - despite it shaping the world of technology since the early 2000s. Some peo ple get money\, some don't - with little rhyme or reason.\n\nThis is a sma ll talk of someone who actively participated in the VC ecosystem. The prim ary goal isn't to bash or praise that industry (though it deserves a lot o f bashing)\, but to shine a light on how it works under the hood.\n\nNote: this is an adapted version of a short lecture I gave at the Mega-Knowledg ecamp (Hacksaar 2025)\n LOCATION:SoS Saal 6 URL:https://hub.test.c3voc.de/en/event/detail/how-does-vc-funding-actually -work-actually END:VEVENT BEGIN:VEVENT SUMMARY:Hold my passkey!

Passkeys promise to free us from both the hassle and the breaches. But will they so lve authentication\, or are they failed by design? A deep‑dive into conv enience\, control\, and everything between.\n\nPasskeys are designed to re place passwords. All you need is your phone or hardware token\, meaning yo u have to remember only one password at most. But isn't that the promise o f password managers? Although they fulfil a similar role\, password manage rs usually use classic passwords\, making them seem like an interim soluti on on the way to more secure authentication. Wouldn't it be great to get r id of passwords once and for all and switch to passkeys?\n\nWhile passkeys promise a passwordless future\, the reality is far more complex. User rel uctance\, questionable usability and corporate interests are making the ca se for passkeys increasingly difficult. So let's delve into whether passke ys do make sense from the perspective of both professional and regular use rs.\n\nThis talk is not a technical deep dive into passkeys\, but rather a ddresses the issues of IT management & IAM and whether secure "passwordles s" auth can work in the real world. The aim is not to give a bureaucratic or opinionated talk\, but to open a discussion about enshittification and whether auth (doesn't) work(s) for both regular and pro users.\n LOCATION:SoS Saal 6 URL:https://hub.test.c3voc.de/en/event/detail/hold-my-passkey-the-password less-future-not-happen END:VEVENT BEGIN:VEVENT SUMMARY:Jurist:innentreffen DTSTART:20251228T103000Z DTEND:20251228T105500Z UID:a2c7e43a-42d0-434b-b9fd-44fd55a6d00e CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/dickma ulrussler\n\nDescription:\nVon Jura-Studis über Rechtsanwältinnen und Re chtsanwälten bis zu Jura-Profs sind alle Jurist:innen i.w.S. eingeladen\, sich gegenseitig in lockerer Runde kennenzulernen und zu vernetzen.\n\nDi e verfügbaren Räume auf dem Congress sind knapp. Daher haben wir im SOS 6 nur 25 Minuten.

Early home-computer “market simulators” s uch as Hammurabi\, Oregon Trail\, and Lemonade Stand encoded entire ideolo gies of productivity\, scarcity\, and profit into a few dozen lines of BAS IC. They taught us how to play the economy — literally.\n\nBut what happ ens when players stop following those rules and begin to rewrite them? Thi s talk explores the power cycles inside these classic games: loops of cont rol between player\, program\, and system. By modifying code\, exploiting glitches\, and bending rule sets\, we can expose how computational models reproduce economic dogmas—and how small hacks can turn libertarian fanta sies into playful counter-economies.\n\nThrough live demonstrations and sh ort historical dives\, we’ll trace how the simple act of “cheating” becomes a tool of critique. Each intervention reveals a new feedback loop between code and ideology: where every CPU cycle becomes a site of politic al power.\n\nCan a hacked simulation still be fun? Can rewriting a game’ s rules help us imagine different systems of value and exchange? Between n ostalgia\, code archaeology\, and playful subversion\, this session invite s you to rethink what—and who—games simulate when we let the power cyc le run differently.\n LOCATION:SoS Saal 6 URL:https://hub.test.c3voc.de/en/event/detail/power-play-cycles END:VEVENT BEGIN:VEVENT SUMMARY:Shift allocation for Video Mixer Angels (Day 3) DTSTART:20251229T171500Z DTEND:20251229T181500Z UID:3da2b1b3-3851-4c78-b4e3-40f8dcebc424 CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/video- mixer-3\n\nDescription:\n LOCATION:SoS Saal 6 URL:https://hub.test.c3voc.de/en/event/detail/video-mixer-3 END:VEVENT BEGIN:VEVENT SUMMARY:Esperanto Schnupperkurs / Esperanto Lightning course DTSTART:20251229T183000Z DTEND:20251229T192000Z UID:21f24081-0093-47fa-986a-a7e017f9324d CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/espera nto-schnupperkurs-esperanto-lightning-c_uzyw\n\nDescription:\nA short snea k peek course to the International language Esperanto.\n\nEsperanto is a p lanned language\, initiated more than 130 years ago by Ludwik Lejzer Zamen hof.

To better equip the broader OSS community with how to doc ument\, detect\, and handle these issues we need to threat model and abusa bility test common governance and community frameworks and publish relevan t guidance.\n\nIn this session\, we are starting with Phase 1: building co mmunication norms. This is because the work that follows carries inherent risk as we identify\, research\, and model these frameworks. We'll also pu blish our recommended communications practices regarding sensitive informa tion in open source.\n\nGithub: [https://github.com/nivenly/securing-open- source-communities-wg/](https://github.com/nivenly/securing-open-source-co mmunities-wg/)\n\nPresentation @ 11:00 Day 4: [https://events.ccc.de/congr ess/2025/hub/event/detail/how-to-keep-open-source-open-without-leaving-our -communities-open-to-threats](https://events.ccc.de/congress/2025/hub/even t/detail/how-to-keep-open-source-open-without-leaving-our-communities-open -to-threats)\n LOCATION:SoS Saal 6 URL:https://hub.test.c3voc.de/en/event/detail/how-to-keep-open-source-open -without-leaving-our-c END:VEVENT BEGIN:VEVENT SUMMARY:📑 Lesezeichen 2: Das JavaScript schlägt zurück 👾 DTSTART:20251230T123000Z DTEND:20251230T132000Z UID:12f961db-5b94-4a65-94ed-28ee1feff1df CATEGORIES:official DESCRIPTION:Full details: https://hub.test.c3voc.de/en/event/detail/leseze ichen-2-das-javascript-schlagt-zuruck\n\nDescription:\nWhat if your browse r bookmarks didn't just save an address\, but unlocked a whole arsenal of features?
