"Sag mal, du hast doch Informatik studiert - du kannst mir doch sicher sagen, wie ich meine Fotos am besten back-uppe?", fragt mich meine Tante neulich beim Kaffee. Wärend meine Tante mir ihre utopischen Anforderungen erklärt, und ich Erwartungs-Management betreibe, frage ich mich wie ich in diese Situation gekommen bin. Und schließlich frage ich mich als Person mit Lehramtstudium: "Was müsste ich...

On the 7th of May 2020, six-weeks after lockdown was announced, the source code for the UK's COVID-19 contact tracing app was published on GitHub. This is the story of how Open Source helped save lives. Come and learn about how we convinced the NHS to open source the app. What pitfalls there were. How we allayed security concerns. What went wrong. How we dealt with trolls. And why it was so import...

To spell bind the audience, gasp, wonder and laugh. Demonstrations, the eerie strange sound of the theremin and it's analogue, the musical saw. Resonance, levitating objects, and the occasional funny smell, now accompanied by Robots, Hugi, Tibbles and Ani. Arduino controlled automata, a cat, a bird and a skull. Even some “Real” Magic Tricks. Presented by an experienced science show presenter. The...

Going for a job in the space industry may seem like a moonshot but it's actually much closer than most people think - and a makerspace is a great place to start from. I now work in the space industry but began my journey into engineering just six years ago by joining a makerspace. Using examples from my own experience - plus some history - I’ll examine how the skills you can pick up as a maker tra...

This talk explains how you can build your own scalable data processing system with just a few open source tools: DBT, Trino, Iceberg and MinIO. And also why SQL is still the best language for data analysis! Have you ever used PostgreSQL to store *massive* amounts of data? Did your queries take *minutes* or even *hours* to compute? The field of data analysis is rather complex and a ton of solutions...

Rücksichtslose Organisationen (zer-)stören unser Klima und unsere Privatsphäre. Klimaschutz und Datenschutz können uns dabei helfen, dass unsere moderne Gesellschaft lebenswert bleibt/wird. Doch wie verhält es sich mit beidem zueinander? Versauen uns die Cookie-Banner die Umweltbilanz? Wie viele Hektar Regenwald kosten uns Datenschutzerklärungen? Und was hat #BingoTechBullshit mit alldem zu tun? I...

Special event - Talk followed by secret film screening What do impact campaigns accomplish in the creative landscape, and what is the role and responsibility of the media in driving that social impact? Inspired by the film "Don't Look Up", where Benn produced the impact campaign, we will explore this dynamic together. When the ethics are no longer focused on being accurate, but rather being first,...

Other industries have their (somewhat pretentious) awards ceremonies, but tech (probably) does not. Let us change that and give away awards for stuff like the best bug turned into a feature, the coolest upcoming open source project, most employees laid off despite a really profitable year, the most interesting timezone handling bug and more. The first Tech Awards Ceremony will be a must-see event...

Für diejenigen in der Bahnbubble, die nicht so im Universum Eisenbahn stecken, dass sie mit den meisten Zugbetreuern im Fernverkehr per du wären, soll dieser Talk einen Einstieg in das informierte Inanspruchnehmen von schienengebundenen Personenbeförderungsdienstleistungen in Deutschland geben. Wie wurde die Bahn überhaupt zu dem, was sie in Deutschland heute ist? Wie funktioniert Zugverkehr eigen...

Die schlechte Unterstützung von Wayland unter Nvidia-Treibern hat zurecht einen Meme-Status erreicht. Aber gerade in den letzten Jahren hat sich einiges getan, um diesen Status zu verbessern, sowohl seitens Nvidias als auch in der Wayland-Community. Und dank großer Fortschritte im Nouveau-Projekt sind Anwender:innen nicht mehr alleine auf Nvidia angewiesen, auch ein vollkommen offener Grafikstack...

This talk will take you through a short history of female protagonists in video games, my experience as a female-perceived person playing games, including how this affects my interactions with others, and will finally look at some research to see the theories behind this, as well as some ideas for how we can make sure video games are for everyone. about this event: https://www.emfcamp.org/schedule...

I'll cover what you can do with a limited budget; lenses and cameras you already own (your phone for example); and what you might expect to see. I'm not a professional, or even a very talented amateur, but tenacity and the willing to sit out in the dark and get eaten by mosquitoes, growled at by foxes and frozen in the winter does sometimes pay off. I've been taking pictures of the sky and things...

GPT PowerPoint Karaoke in 2022 was a hit — but also GPT was toooooo good at generating the topics. Let’s go retro: HR training manuals, overhead transparencies, terrible diagrams from 1970s Open University TV programmes, and random photographs. Then we make people from the audience give talks on subjects they don’t know about with slides they’ve never seen. Licensed to the public under https://cre...

In 2022 we convened a group of artists, technologis...

This talk will take a look at Älgen, a custom-built guitar that is a fusion of traditional hand-crafted woodwork and advanced 3D-printing and generative-design techniques. The guitar is built using no less than 4 different types of 3D-printing, including 3D-printed aluminium. At the same time it sticks with traditional hand built woodwork for the playing surface, matching material with function. T...

Was ist dieses ADHS eigentlich, warum gibt es so viele betroffene Personen und was kann eins mit dieser (manchmal) so tollen Superkraft alles machen? Hi, ich bin Niggo und ich habe ADHS. Auch wenn’s eigentlich obvious ist, wurde ich erst viel später als mir eigentlich Recht ist mit dieser Realität vertraut. Seit meiner Diagnose habe ich vieeeeeel über mich selbst, die Art und Weise wie ich denke g...
