Not sure what to do with your discarded, never working, inkjet printers? Rosa Schuurmans and Riviera Taylor combine the sound of printers with the craft of live coding. Together they hack discarded printers and connect them to live coding environments on computers to generate analogue sounds from digital messages. Printer Jam welcomes familiar, mechanical quirks and the inherent noise of printers....

Der klassische Sicherheitsansatz ist im Zeitalter von Plattform-Engineering und Cloud-Geschwindigkeit nicht mehr haltbar. Mit der Beschleunigung der Software-Entwicklung und -bereitstellung muss die IT-Sicherheit nicht mehr als Hindernis, sondern als Katalysator für die digitale Transformation gesehen werden. Das Ziel der IT-Sicherheit ist nicht nur die Gewährleistung eines sicheren Laufzeitschutz...

Dieser Vortrag sucht die Antworten mit einer Analyse offener Wahldaten – und liefert überraschende Erkenntnisse. Die Wahlen zum Deutschen Bundestag sind komplex: Erststimmen, Zweitstimmen, Überhang- und Ausgleichsmandate,...

Tastaturen...das periphere Eingabegerät, dass uns die Möglichkeit gibt, eins zu werden mit unseren Systemen, Werkzeugen, und uns ermöglicht, das zu tuen was wir lieben. Es gibt Tastaturen wie Sand am Meer. Viele sind wunderbar und viele sind Schrott, Mechanical Keyboard sind keine Randerscheinung mehr. Trackballs, Ergonomische Mäuse, Stühle und höhen verstellbare Schreibtische... Und doch beherrsc...

Overstory uses satellite imagery plus machine learning to understand individual trees - at scale. I'll talk about how we do this, some of the practical challenges of remote sensing and earth observation, and how we translate this into real world prevention of wildfire and power outage by working with utilities, who manage many thousands of miles of power cables. about this event: https://www.emfca...

Fotografieren auf Chaos Events ist eine Herausforderung. Im Vortrag möchte ich Möglichkeiten zeigen wie es trotz unterschiedlicher Regelung möglich ist cool Bilder zu machen und die Stimmung bestmöglich einzufangen. Fotografieren auf Chaos Events ist eine Herausforderung. Veranstaltungen wie das Camp oder der Congress haben eine eher restriktive Foto-Policy, die GPN dagegen hat eine eher liberale...

Passwörter sind nicht mehr zeitgemäß! Seit 2023 wird viel Hype um das Thema Passkeys betrieben, viele IT-Dienstleister, Cloud-Anbieter und Mailprovider bieten das System schon an. Aber wie funktioniert das eigentlich? Wie gut ist die Nutzbarkeit, im Vergleich zu Passwörtern und Multi-Faktor Authentifizierung? Warum sind passkeys immun gegen phishing und was unterscheidet sie von "herkömmlichen" Au...

As a semi-professional plane spotter when I hear or see an aircraft fly over I will sometimes point at it. But I can't always tell if there's an aircraft flying over, and I can't be awake 24/7 so I miss some, which I find unacceptable. Enter the auto spotter, a robot that is capable of pointing at the nearest aircraft continuously. The auto spotter uses 1090Mhz ADS-B Out transmissions to work out...

Few things are as polarizing today as the production of oil, and unconventional production (including 'fracking') is even more controversial. Whether you're for it or (more likely) against it, it's well worth knowing what is actually involved in making it happen and where the real risks are. The presenter recently left a long career in the US oil industry and will give you a view into this world w...

It isn't just you. There are so many pressures on us, not only from our jobs and industry, but from the state of society, politics and the economy as a whole. Join me on a joyful journey through the alphabet of overwhelm, we’ll cover Anxiety, Burnout, Capitalism, Depression, Emotional Labour and many other fun factors. We’ll talk through how to recognise symptoms in yourself and your friends. Lets...

What do semaphore, octopuses, Scrabble, rotary telephones and Microsoft Paint have in common? If you've been to previous EMFs, you might recognise these as some of the themes for our puzzles! We are Dreamcat and we are a group of friends who made our first puzzlehunt for EMF 2018 and haven't stopped since. We love the combination of escape room, treasure hunt, video game, and just a dash of immers...

Tidal energy is one potential source of green energy but the impact of placing large turbines on the seabed is not fully understood. In particular, how are sea mammals coping with such changes in their environment? Do we need to put automatic mitigations in place – is it even possible? For over a year, we have been annotating more than 60 terabytes of data, finding these rare events of interest. W...

Join BAFTA winning digital artist Seb Lee-Delisle in this engaging talk about his life and work over the past few years. Although Seb is known for his large and spectacular outdoor light and laser shows, he is fundamentally a coder. In this fun keynote, he’ll talk about the unique challenges of working with computers at this scale, and demonstrate how to code mesmerising particle effects with an a...

Internet voting allows you to submit your vote over the internet using your own device. This talk will give an introduction into the topic: Why might governments, associations or political parties turn to internet voting? What are the security requirements of such a system, and how does this differ to e-banking or postal voting? How do such systems work, and what separates a bad from a good (or at...

Um mit Retro-Spielen Spaß zu haben, braucht man entweder die alte Originalhardware oder man greift zu PC und Emulatorsoftware. Was wäre aber, wenn man die alte Hardware nachbilden könnte? Ich zeige, wie man mit sogenannten FPGAs fast vergessene Technik auch ohne Lötkolben daheim nachbaut und so alten Spielen neues Leben einhaucht. FPGAs (Field Programmable Gate Arrays) sind eine eigene Chip-Famili...

Woher kommen sie? Was sind sie? Und wo gehen sie hin? - Ein Einstiegs-Talk mit vielen Live-Demos über das Erstellen, Modifizieren und Zurückziehen von PGP (Pretty Good Privacy) Keys in GnuPG (GNU Privacy Guard). E-Mail ist selten Ende-zu-Ende verschlüsselt. Eine Möglichkeit, Vertraulichkeit und Integrität in E-Mail sicherzustellen ist PGP. Wenn mensch nicht weiß was mensch tut und z. B. nur Keys m...

Computing is riddled with security vulnerabilities, many of which arise from memory safety issues. Conventional hardware architectures and the C/C++ codebase are chronically prone to exploitable errors - a 75-year-old problem at the heart of computing. This talk will introduce CHERI, showing how (finally?!) we can do better. The CHERI research project has developed a new architecture+software appr...

A bit more than two years ago, someone contacted our Hackspace asking if we would be interested in an electronically defective, but probably repairable industrial coffee vending machine. An industrial coffee machine with a touchscreen and cocoa toppings? No idea where we would find enough room for it or if it would actually be used, but of course we'd be interested! After a few months of collectin...

The Roman archaeological record is far from complete; There are hundreds of high status Roman buildings yet to be located in Britain. I was volunteering in the ambulance service during COVID when I was given a piece of Roman pottery by a patient. With no training (I later embarked on an Archaeology degree ), I started to carefully investigate and record what is now established as an enigmatic high...

I recently released Downpour, an app that anyone can use to make little games on their phone. And before that I made Cheap Bots, Done Quick, a website that anyone could use to make a Twitterbot on their computer. And so unsurprisingly I am a big advocate of making creative tools - I love the feeling of seeing other people make cool stuff, and knowing that I enabled that to happen. In this talk, I'...

There are three things about this poem that will surprise you. First: though written 300 years ago, it contains superb guidance on being an engineer or maker of any kind. Second: you’ll immediately recognise some of its best lines. Third: its author was an indomitable twenty-three year old hunchbacked dwarf, who had educated himself due to religious persecution. I hope you’ll take away some maxims...

Earlier this year, a developer was trying to benchmark a database. But something was wrong - SSH was taking up too much CPU time in the background. This accidental observation led to the discovery of an audacious attempt to introduce a backdoor that would allow an attacker access to almost any system in the world running SSH, an attack made up of both technical and social components. This talk wil...
