If you are a British nerd of a certain age, you almost certainly played Elite on the BBC Micro. And if you didn't, this talk will explain why you should care about a now 40-year-old game. It was years ahead of its time, with 3D graphics, a procedurally generated open world, and a whole novel's worth of lore - all running on an 8-bit home microcomputer in 1984, when most games were little more adva...

We'll show you all the cursed uses of bash you didn't want to know about. Implementing network protocols, compilers, and emulators? Coming soon to a /bin/bash near you! During the presentation, we'll show you the really juicy details of how we stretched bash to its absolute limits in some of our craziest projects, while also teaching you about features that will hopefully one day prove useful in y...

Ein Erfahrungs- und Leidensbericht darüber, wie man Qualitätskontrolle mittels KI/ML an Produktionslinien umsetzen kann. Und das alles über Eigenentwicklungen - wir haben Interna von Tensorflow gesehen, die sonst wohl nur die wenigsten sehen. Ein Erfahrungs- und Leidensbericht darüber, wie man Qualitätskontrolle mittels KI/ML an Produktionslinien umsetzen kann. Und das alles über Eigenentwicklunge...

Die zu Grunde liegenden Fehler, die Ransomwareangriffe ermöglichen (und einfach machen), sind häufig über verschiedenen Kunden hinweg die gleichen. Dieser Talk ist nicht nur ein Rant über immer gleiche Fehler, sondern soll IT-Verantwortlichen praxisnaher Empfehlungen zur Absicherung der IT-Infrastruktur geben. Denn die gute Nachricht ist: Der weitaus überwiegende Teil der Ransomwareangriffe lässt...

Offline RFID systems rely on data stored within the key to control access and configuration. But what if a key lies? What if we can make the system trust those lies? Well then we can do some real spooky things… This is the story of how a strange repeating data pattern turned into a skeleton key that can open an entire range of RFID access control products in seconds. It’s a scrappy but scary hack...

During the pandemic, trains got weird for a while. We weren’t quite sure whether it was safe to travel collectively, and the impacts of that difficult time continue to shape our railway network to this day. Meanwhile, many of us were exploring our own, hyperlocal neighbourhoods on foot with obsessive levels of depth that we never otherwise would have got around to. (Was I the only one who highligh...

For two weeks every summer, half a million people attend the oldest and most prestigious Tennis Tournament, with another billion people following from afar. Underneath the pristine courts of Wimbledon, a massive technology operation underpins almost every aspect of the event, from the grass growing, to the scores appearing on screens around the world. This talk will cover the many interesting ways...

Gas boilers, almost all homes in the UK have them, but they are dreadful! +90% of the ones I've seen are badly spec'ed and horribly configured, so they burn way too much gas. Then Martin Lewis keeps telling us to "lower the flow temperature" but it's never really explained how to, or what this does to save gas (and money). Well have I got a Slide Deck for you!! As with any serious problem, it need...

I’m an archivist. Every day I deal with the records that people chose to save, or forgot to destroy. Archival material ranges from the sublime (Royal wills, lost love letters, newspapers announcing the Titanic’s demise) to the ridiculous (broken chips of wax from old seals, IOUs from unknown persons, too much human hair). A key role of an archivist is to decide what to save and what to destroy. Bu...

What does a computer programmer do if they can’t type code? Speak it, of course! Like many programmers and heavy computer users, I suffer from chronic hand pain aggravated by computer keyboard use (often called repetitive strain injury, or RSI). After having mild symptoms for years, in 2019 my hand pain worsened from irritating to unignorable. Eventually I got desperate enough to try to learn to c...

Files and directories feel like the Sun and Earth: they are the eternal foundations, and pretending they don't exist can only make make things worse. Except files were invented by humans! What if we left our zone of comfort and explored the possibilities? We live in the world of hierarchical file systems. We juggle named files, named directories, and symbolic links daily. It has been this way sinc...

Writing schematics via code isn’t a new idea. But with new open-source projects like Atopile, this workflow suddenly makes a lot more sense. Let’s take a look at why one would even write schematics in code instead of using the established visual way in software like KiCad or Altium, the advantages (from git integration, reusing components & modules, AI support, and more), previous software project...

Das ZKM | Hertzlab ist als künstlerische Forschungs & Entwicklungsabteilung des Zentrums für Kunst und Medien Karlsruhe die zukunftsgewandte Abteilung. In sechs Themengebieten beschäftigen wir uns mit der Frage, was in 100 Jahren ist, wie wir da hinkommen und wie wir das eigentlich hinkriegen, dass das eine lebenswerte Zukunft für alle ist. Wir geben einen Überblick über aktuelle Projekte des ZKM...

Controlling websites with an Arduino is like magic. Suddenly little bits of hardware can control all kinds of games and interfaces on screens. And building a UI for your electronics becomes trivial too. This is a talk for anyone who’s ever tinkered with hardware or web design, and wants to join the physical to the digital. During this talk I will explain the basic techniques of keyboard emulation...

This is the story of Reading Hydro, how a group of volunteers built and are now operating a hydro generation plant on the Thames in Reading. From raising the £1.2M to the parts build by volunteers, and how they are now operating the plant.

Single Sign-On (SSO) is sold as a way to • centralize managing your organization’s users, • make life easier for your colleagues, and • enforce consistent security standards. But SSO protocols are just ways for an identity provider to share information about an authenticated identity with another service. Me having a way to tell my vendor “yeah, that’s Bob” doesn’t tell me what the vendor does wit...

A talk looking at Off-Grid Renewable Energy technology and off-grid living. This presentation is based on 20 years of off-grid living experience and showcases case studies from an off-grid eco-village from 2000 to 2018. The talk aims to share some of the knowledge gained and look into the possibilities for future renewable off-grid living opportunities and how new technologies might be used to imp...

I was trained as a tax lawyer and data scientist as a profession but I always wanted to build. I attended the my first EMF and was hugely inspired by the participants and presenters I met. The following year, with the support of an EU innovation grant, I embarked on a 6-month product design course, culminating in an interactive children's book inspired by the Art of War. This unique book blends st...

How do you transmit data when there’s 205,000 people trying to access the same mobile network in a field? Satellites, of course! After facing dilemmas of tracking the staff shuttles at a major UK festival, we decided to look at other options and discovered some cheap Iridium satellite constellation hardware on eBay. When they arrived, we surveyed what we had purchased, discovered it was ex-Ministr...

Wie baut man eigentlich ein Hochvakuumsystem ohne dabei bankrott zu gehen und was kann man damit so machen? In diesem Talk werde ich über meine 4-jährige Reise durch Hochvakuumsysteme berichten. Hochvakuumsysteme sind die fundamentale Basis für einige große Bereiche der Physik wie etwa Elektronenmikroskopie, Massenspektronometrie und Dünnfilmbeschichtung. Ich bin von diesem Thema seit meinem erste...

​​Debuggers are indispensable tools for all Python developers, empowering them to conquer bugs and unravel complex systems. But have you ever wondered how they work? Curious about the implementation of features like conditional breakpoints and single stepping? Join me for a talk in which we create our own debugger with conditional breakpoints, single stepping, and a Python-based debugging shell an...

Wer in der Chaos Community unterwegs ist, trifft unweigerlich auf Nix. Doch ist es das von vielen geprädigte Allheilmittel für IT Sorgen? Wann ist es wirklich Sinnvoll? Mensch könnte den Eindruck haben, dass in den letzten Jahren NixOS in der Chaos Community zum neuen ArchLinux wurde. Egal in welchen Hackspace man geht, findet man eine Gruppe an NixOS affinen Haecksen und Hackern die am liebsten j...

This artist talk presents two mobile-device art applications developed for use with bicycles in the summer of 2021: SpeedPitch is a simple augmented sonic reality experiment that alters music playback speed based on your actual GPS ground speed. The faster you go, the higher the pitch and sudden stops lead to dragging audio samples. Natural motion leads to unnatural sound. ShadowPlay is an explora...

Seit zehn Jahren stellt das Projekt OpenRailwayMap eine thematische Karte bereit, die Informationen über die Eisenbahninfrastruktur aus der OpenStreetMap-Datenbank darstellt. Wie werden diese Informationen von Freiwilligen erfasst? Welche Informationen können in OpenStreetMap erfasst werden? Wie kann man beitragen? Auch andere Nutzungsmöglichkeiten, z. B. Routing und Geocoding, der Daten werden im...
