Kubernetes has had a rapid ascent to default cloud infrastructure. However, this didn’t happen simply because Google open sourced it. This talk will share the messy human side of the community architecture and how that investment has paid dividends in bringing more under represented minorities into open source leadership. I’ll offer tips and tricks to intentionally manage humans when you have no authority. you can also expect some of the more complicated situations explosive growth combined with emergent organizing can lead to when governed by those who show up.

Atuin is a command line tool for searching and synchronizing shell history across devices. I'll be telling the story of how I accidentally made a popular open source project, diving in to how it synchronizes and encrypts data, and covering some of the lessons learned from working in public For disclosure; I currently work on Atuin, which is what this talk is about. about this event: https://www.emfcamp.org/schedule/2024/160-keeping-shell-history-in-sync-with-turtles-and-magic

Im Automotive Bereich gibt es viele neue Standards die eine einfache Vernetzung über 2 Draht Leitungen bis 2,5 Gbits ermöglichen. T1S mit Multidrop ermöglicht es einfache Interfaces, wie LIN, CAN, UART, etc. ins Netzwerk zu bekommen und das alles in einem einfachen Bussystem. Ebenso ein Überblick über die momentan herrschenden Standards und wie man das in vorhandene Projekte bekommt. Beim Besuch des diesjährigen Automotiv Ethernet Congress gab einen Einblick in jetzigen Standards, interessante Bauteile. Dies hat auch noch mal zur Änderungen beim WomoLIN Projekt geführt. Welche Steckertypen werden verwendet, was ist beim erstellen der Leiterplatte beachten muss, wie integriere ich Ethernet PHYs und Switches. Welche Verschlüsslung findet direkt an der physischen Ebene statt. about this event: https://cfp.gulas.ch/gpn22/talk/MVPTEK/

Critical research on digital influence and micro targeting has generally focused on privacy violations by commercial marketers and Cambridge Analytica-style political manipulation. But increasingly, the UK government, police, and security services are using these tools for public policy. The targeted advertising and influence platforms give public sector actors complex tools with which to target behaviour change communications - allowing them to tailor nudge messages based on online behaviour, interests, and fine-detail location. This is allowing the police to use targeted behaviour change advertising to attempt to prevent crime before it happens - but poses serious questions for accountability, ethics, and privacy. Drawing on a dataset of more than 12,000 government adverts from the Meta Ad Library and in-depth interviews with law enforcement, we map the landscape of what we call 'influence policing' in the UK, and discuss the ethical and democratic implications of this new mode of policing. about this event: https://www.emfcamp.org/schedule/2024/237-influence-policing

Hin- statt wegsehen, zur Polizei gehen statt weggehen - warum wir uns alle trauen sollten, mehr Zivilcourage zu zeigen und wie dabei der Selbstschutz gewahrt bleibt. Was ist das eigentlich, "Zivilcourage", was bedeutet sie, warum brauchen wir sie heute noch mehr als früher - und zwar offline und online? Das müssen wir in diesem Talk klären. Erst dann können wir uns Fragen widmen wie: Wie erkennt man, ob Menschen unsere Hilfe brauchen oder wir uns (unerwünscht) einmischen? Wie spricht man Opfer an, gerade bei Unsicherheit, ob sie Hilfe brauchen und wollen? Sollten wir das Einmischen lassen, wenn wir unsicher sind? [Spoiler: Nein.] Jede*r kann und sollte Zivilcourage zeigen, unabhängig von Alter, optischen und körperlichen Merkmalen, Herkunft ... aber sich niemals selbst in unkalkulierbare Gefahr begeben. Deshalb müssen wir darüber sprechen, wie wir Zivilcourage zeigen, aber Selbstschutz wahren, können. Und uns vergegenwärtigen, dass echter Einsatz nicht endet, wenn Polizei, Behören und Justiz übernommen haben, sondern dann (vielleicht) erst anfängt. Im dritten Teil des Talks müssen wir über für Opfer gefährliche Arten reden, nicht zu helfen. Nicht, weil gut gemeint oft nicht gut gemacht ist. Sondern, weil Zivilcourage auch heißt, sich im Namen der Opfer gegen untätige Behörden aufzulehnen, auf Täter-Opfer-Umkehr, Victim Blaming und sekundäre Viktimisierung aufmerksam zu machen. Und natürlich wird der Talk auf meine persönlichen Erfahrungen mit Zivilcourage eingehen. Ihr werdet erfahren, warum mich manche Menschen "SEK-Wawuschel", andere "die ominöse Frau mit den giftgrünen Haaren" (oder noch fieseres) nennen - und mir das egal ist. about this event: https://cfp.gulas.ch/gpn22/talk/J3MKEY/

Die Geschichte wie ein simpler Temperatursensor zu einem Großflächigen Energiemonitoring im Industrieumfeld eskalierte. Als frisch ausgelernter Facharbeiter rutschte ich in die Position des Prozessoptimierers, doch eine kleine Idee mal eben die Hallentemperaturen zu messen startete ein Projekt, das in 2 Jahren doch etwas eskalierte. Das Projekt soll auf lange Sicht komplett Open-Source werden, vielleicht ist ja was für euch dabei. Wie es dazu kam, was man mit Siemens, Node-Red, TimescaleDB und Grafana so alles im Industriebereich anstellen kann, und was ich auf dem Weg gelernt habe, das erfahrt ihr im Vortrag. about this event: https://cfp.gulas.ch/gpn22/talk/FNUJQR/

Emily Peasgood and Mark Hanslip will present a talk on creating EverSong, followed by an invitation to try their vocal transfer models in real-time. EverSong is a sound installation where you can hear the lifespan of a person in a song, from 5-years-old at the start to 95-years-old at the end. It explores the fragility of life, its circularity, invites people to celebrate the moment we are in right now and questions our legacy as humans moving into an increasingly digital age. Since January 2024, Peasgood & Hanslip have worked with DDSP-SVC, a newly-developed process which builds on Google Magenta’s DDSP by combining it with a diffusion-based vocoder. They recorded vocal datasets with people aged 5-95 and trained models which can be mapped onto Emily’s voice enabling her to sound younger and older than she is. This technology is starting to be adopted by contemporary pop musicians, high-profile examples being web services such as Grimes’ Elf and Holly Herndon’s Holly+. EverSong represents a new application of this technology by making it possible to hear a voice age in real time. It will be experienced in tunnels and pathways, installed sustainably in nature, touring before finding a permanent home in an ancient site. about this event: https://www.emfcamp.org/schedule/2024/120-eversong-singing-voice-transfer

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 advanced than Pac-Man or Space Invaders. Over the last few years, I've been picking apart the original Elite game engine to understand how it worked, and also to experiment with extending it. In this talk, I'll examine some of the methods that the game used - how it used the graphics hardware, how the game state is represented in memory, how the ship models were designed, how the AI worked, and how galaxies and planets were generated. I'll also explain some quirks of the game... including the real reason that docking was so hard. I'll demonstrate some new tools I've developed, which access the game state in real time, letting you experience the original game in new ways - including an OpenGL frontend with VR support, and an attempt to recreate an arcade-style version of the game, with an old-school vector display. Finally, if all goes to plan, I will attempt to demonstrate something that was an impossible dream for 40 years: multiplayer Elite on the original BBC Micro version. about this event: https://www.emfcamp.org/schedule/2024/113-exploring-and-extending-the-elite-game-engine

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 your own down-to-earth scripts. This is a high effort shitpost: we woke up one day and chose violence — if in "violence" you include using bash for the things that really should use a systems programming language, that is. We implemented emulators, network servers, parsed text and binary data alike, and crafted libraries to help with all of the above – just so you don't have to wonder: "could it be done"? about this event: https://cfp.gulas.ch/gpn22/talk/TL97JJ/

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 sich mit der Umsetzung relativ grundlegender technischer und organisatorischer Maßnahmen frühzeitig verhindern. about this event: https://cfp.gulas.ch/gpn22/talk/GUYAHS/

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. Im Talk werde ich die Entwicklungen zeigen, die ich weitgehend alleine, teils auch im Team, seit ~2019 für einen Industriekonzern umsetzen durfte. Das ganze entstand aus einem Hobbyprojekt, was nun Millionen von Teilen mittels Kamera und KI-Modellen auf Fehler prüft. Und was wir dabei gelernt und erfahren haben möchte ich euch nicht vorenthalten. about this event: https://cfp.gulas.ch/gpn22/talk/NAFLDR/

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 highlighted every street I walked in a London A-Z to see if I could get complete coverage?!) In 2021, I did a design-based MA all about railways, railway infrastructure, and what it means to travel and live communally. To do this, I walked all the way from London to Brighton (in sections), following the railway line as closely as possible. This is a talk about what I saw and what I thought about, and will hopefully be enjoyed by fans of trains, hiking, community and travel. (And anyone else who fancies a sit down, I’ll try and make it interesting, I promise) Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://www.emfcamp.org/schedule/2024/69-london-to-brighton-by-train-and-on-foot

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 that spawned from something we noticed whilst trying to duplicate an access card onto a subdermal RFID implant. This covers the discovery of the flaw, how we investigated it, and how significant the flaws ended up being. about this event: https://www.emfcamp.org/schedule/2024/80-digital-skeleton-keys-we-ve-got-a-bone-to-pick

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 that technology supports this huge live event as well as a behind the scenes peek of the IBM operation in the broadcast centre.

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 needs hard data. So I wired my Raspberry Pi home server to my central heating controls, wrote a bunch of code, and spent last winter collecting data from my boiler, a dozen temperature sensors, some humidity sensors and the Octopus Energy API. I have pretty graphs to show what happens all around my home, how altering the flow temperature works, how altering set points work, why my house was too cold, then too hot, and used way too much gas. I'll explain the (simple) physics and how to tweak your system for best performance too. But ultimately, we all have to stop burning gas and move to heat pumps, a solution not understood by many and requiring something of a mind shift from the way gas central heating has always worked. I'll explain how heat pumps work and what you can do to prepare for their arrival in your home. The future is bright, and it's heading rapidly in this direction. about this event: https://www.emfcamp.org/schedule/2024/161-gas-boilers-suck-hack-yours-today-save-money-save-the-planet

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. But this is the past. Today most records are no longer on paper but sent in the form of bytes and I’ve started to wonder what the point of my job really is? We have free access to near-unlimited email inboxes, all our photos are backed up to the cloud to access from anywhere, and instant messaging is synced between our devices. Why bother deciding what to keep for posterity? Just save everything, let computers do the hard work, and all will be well. This approach unsettled me so much that I set off to explore what it would really mean if we “saved everything”: how this would affect our world, communities, and ourselves as humans. In this talk, I will share this journey and my thoughts with you, and try to persuade you that my job is not in fact pointless. about this event: https://www.emfcamp.org/schedule/2024/253-are-archivists-pointless-when-the-cloud-can-just-save

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 code by voice. To my surprise, it worked. Speech recognition technology has advanced dramatically in the past decade, but most people’s ideas about voice-driven UI are based on highly limited voice assistants like Siri or Alexa, powerful but imprecise tools like LLMs, or special-purpose dictation tools. What does a voice interface for precise control by expert users look like? A small but growing community of programmers, many affected by RSI, have been developing tools that explore this question. I use one such tool, called Talon, to control my computer, write and edit computer code, and even to write my dissertation. In this talk, I will live-demo how I edit code by voice, as well as tackling the following questions: 1. What is voice-coding like? What unique challenges does it present? 2. How do voice control systems like Talon work under the hood? 3. Could voice coding ever be *better* than typing? 4. What can we learn from all this about designing voice interfaces for expert users?

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 since the days of DOS, and it remains this way now. It's just the way it is. Or is it? Phone operating systems try to hide the underlying file system from the user. Yuck! Or actually, do we really want to manage our files manually? Is it really that fun to decide if the train ticket to FOSDEM goes under the "2023" or "invoices" directory, and in which order? Or do we just want to find the cursed thing when we need it? Documents have not always been bound to files, and they aren't, and they don't have to be. Put away the Stockholm syndrome, and I'll tell you about semantic desktop, WinFS, alternate streams, [photo managers](https://www.digikam.org/), [Perkeep](https://perkeep.org/), [IPFS](https://ipfs.tech/), and my own plan to ascend. about this event: https://cfp.gulas.ch/gpn22/talk/ZRKD3G/

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 projects in that field, the current development state and how you can try out this new workflow yourself. Ideally, you already have experience in PCB design, but also PCB design newbies can learn a lot in this talk and learn some tricks for their first circuit board design. about this event: https://cfp.gulas.ch/gpn22/talk/RUW3HF/

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 and using the Javascript Web Serial and Web Bluetooth APIs. To make it fun, and introduce some peril, I will demo all of the techniques live: controlling the Google Chrome Dino game by jumping up and down on stage, making a musical instrument from stretchy rubber and allowing audience members to connect to a set of handbells from their phones. Along the way will be plenty of tips on what to buy and what to avoid, I’ll demystify some of the complexity around Bluetooth and USB, and share several ideas for how to use this to cause mischief amongst friends, colleagues and enemies. I have done this before, but only once. Fingers crossed.

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 with this information, or if the vendor always asks me who’s coming in the door. A bad SSO implementation can make you think you’re safer, while hiding all the new and fun things that have gone wrong. To get the most out of implementing SSO, I need to know what I’m trying to accomplish and what steps I need to follow to get there. To illustrate why SSO needs to be set up carefully, for each of the things you need to do right, I’ll give you some fun examples of creative ways you and your vendor can do this wrong. We all learn from failure, right??? I’m sharing this info because this year I got deeply involved in the SSO setup for several vendors at work. It turns out that I’m good at asking weird questions, and it’s an extremely valuable thing to do. If you know how things should be, then you know where they could be broken, and you can ask your vendors (and your colleagues!) “weird questions” before an adversary does. about this event: https://www.emfcamp.org/schedule/2024/233-omg-wtf-sso

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 storytelling with 3D paper origami, touch sensors, cloud-based audio features, making ancient wisdom fun and engaging for young minds. In my talk, I'll share the challenges and triumphs of this unexpected adventure, from design principles to prototyping hurdles, offering valuable insights for aspiring makers and seasoned professionals alike.
