Flightgear is an open source flight simulator, We take a look at it, how to get started flying and how to hack on it. Since the release of the Microsoft Flight Simulator 2020, flight simulation has become a more mainstream genre. What flies past many is the existence of an open source flight simulator with a long standing history and way more flexibility in many regards. We take you on a flight through the world of Flightgear... In the first part we will take a look at the history, where the project is headed in the future and how you can make the first steps in the simulator, helping you get in the air. Now that we have an overview what flightgear is, we go on to the second part where we take a look how to interface the flight sim with your own hacked hardware and other systems. We will show you for example our first PCB design we're working on right now which will be a control interface for the simulator as well as similar projects from the community. about this event: https://cfp.gulas.ch/gpn22/talk/KUEALJ/

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 translate over to the space sector, how there are plenty of similarities between hobbyist making and professional space engineering, and how Makerspaces teach skills that are actually in great demand in professional engineering! Where there isn't a direct link from makerspaces into professional work, I'd like to go briefly into what skills you should look to pick up, and how to do it, if want you to go for a space job!

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 important to be as transparent as possible. This talk asks if we did the right thing? Should have done something differently? Could we have been more open? Were the risks justified? Was being Open Source a help or hindrance? This is a personal recollection of a very strange period in health-tech history.

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 are available: therefore I will show how to compare systems with each other. You will learn why databases like PostgreSQL or MongoDB are not suited to compute analytics queries on huge amounts of data. Then we will look at data analysis architectures that are capable of scaling to terabytes of data and I will explain why they are better in those particular situations. At the end of the talk you will know which solution is best suited for your next large-scale data project! about this event: https://cfp.gulas.ch/gpn22/talk/L3SXWL/

This talk will provide an overview of all the pieces it takes to receive data via Wifi. Starting with the basics of encoding information in wireless signals we will go over various building blocks (hardware and software) needed to receive bits and bytes via Wifi. Deep Dive into the 802.11 Wifi standard. The talk starts with an overview of which hardware is involved into receiving Wifi signals and how signals get converted into bits. During the talk we will explain the hurdles which need to be taken to receive Wifi and which solutions the Wifi standard describes to solve them. We will also look into several real world Wifi implementations based on SDR transceivers or proprietary datasheets from Broadcom. In the end we will briefly discuss what would be necessary to create open source firmware for full-MAC Wifi chips. about this event: https://cfp.gulas.ch/gpn22/talk/MTNMRD/

A gentle introduction into the security concepts offered by modern POSIX systems: Kernel Sandboxing and Privilege Separation This talk will cover two concepts that are crucial in modern applications: Sandboxing and Process Separation, as well as the combination and necessity of these two. As programmers, we often make tiny silly mistakes. Tiny silly mistakes, that lead to unnoticeable bugs, which might be exploited in the most dangerous and ugliest ways. Acknowledging this fact, by restricting the powers of a process, makes the impact of potential exploits much harder. After this talk, the audience will know about the necessity of sandboxing, the history of security in operating systems in general, as well as the current mechanisms used to secure modern applications. about this event: https://cfp.gulas.ch/gpn22/talk/Y8VRLY/

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? In diesem Talk stelle ich die Methoden und Ergebnisse meiner Bachelorarbeit ([ba-thesis.blog.luap42.de](https://luap42.de/notes/ba-thesis/)) zu den Klimaauswirkungen des Datenschutzes vor. Ich gehe darauf ein, wie #BingoTechBullshit ("KI", "Bl*ckchain" etc.) sowohl dem Klima- als auch dem Datenschutz schaden, und was als Gegenteil datenschutz- und klimafreundliche Technologien sind. about this event: https://cfp.gulas.ch/gpn22/talk/7HQPLZ/

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,and being attention grabbing, it becomes difficult for people to discern what is and is not an important story. So we wonder how some of the most important stories either fall through the ether entirely, or are seen and dismissed by the apparatus of the 24 hour news cycle and 3 second refresh feeds. That's what films like Don't Look Up tackle so well. Benn is a SXSW Grand Jury Prize & UNICEF Prize winning, Oscar Shortlisted, Webby nominated producer. He has been a social impact advisor and producer working across film, games and events, with a mission to bridge gaps between story and policy, and ultimately champion vast perspectives to aid social movement. He is the Head of Partnerships for Neon Picturehouse, and Executive Producer & Vice-Chairman of HF Productions. He serves as an Advisor of Think Film, Global Environment Media, Screen South, SIE Society, and Treun House Atelier. Benn also consults on projects from producing Netflix impact campaigns (“Don’t Look Up”, “Breaking Boundaries…), Sony’s Picture This, and SDGs in Action with UN DESA as part of the High Level Political Forum. about this event: https://www.emfcamp.org/schedule/2024/630-the-role-of-media-in-impact-campaigns

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 eigentlich? Welche Tools gibt es, um meine Bahnreise besonders effektiv zu gestalten und auch bei Problemen mehr als die anderen Fahrgäste (und manchmal sogar das Zugpersonal) zu wissen? All das und mehr wollen wir in diesem Talk beantworten. about this event: https://cfp.gulas.ch/gpn22/talk/FUNVJJ/

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 scheint wieder in greifbarer Nähe. Daher stelle ich mir 2024 wieder die Frage: Lässt sich Wayland endlich problemlos mit Nvidia-GPUs nutzen? Seit 2021 gab es einige Meilensteine, die die Unterstützung von Wayland auf Nvidia-GPUs Stück für Stück verbessert haben. Dies geht von der teilweisen Öffnung der offiziellen Nvidia-Treiber über eine Annäherung Nvidias an die Wünsche der Wayland-Community bis zu den kürzlichen Fortschritten des Nouveau-Projekts, aktuelle Nvidia-GPUs nicht nur zu unterstützen, sondern auch offene Treiber für Vulkan und OpenGL zu liefern, die vollkommen standardkonform sind. Es scheint also, als könnte dies das Jahr des Nvidia-Linux-Desktops werden. In diesem Talk wollen wir uns anschauen, was mittlerweile alles möglich ist, sowohl in Bezug auf Gaming als auch die alltägliche Nutzung des Desktops. Welche Unterschiede gibt es dabei zwischen den verschiedenen Desktopumgebungen? Wie viel manuelle Konfiguration ist noch notwendig, um das beste Wayland-Erlebnis zu erreichen? Und lohnt sich der Umstieg auf Nouveau? Einige nennenswerte Fortschritte der letzten Jahre sind: - Juli 2021: Xwayland, die Kompatibilitätsschnittstelle, um X11-Anwendungen innerhalb einer Wayland-Umgebung auszuführen, erhält Hardwarebeschleunigung für Nvidia-GPUs. Da gerade Spiele (und Wine/Proton) vorrangig nur unter X11 laufen, wird Wayland zum ersten Mal für Spieler:innen mit Nvidia-GPUs interessant. - Oktober 2021: Nvidia veröffentlicht die erste Treiberversion mit Unterstützung für Generic Buffer Management (GBM), einer offenen Schnittstelle zum allokieren von Render Target Buffers, die in allen Wayland Compositors zum Einsatz kommt. Zuvor hatte Nvidia versucht, die eigene Lösung EGLStreams als "bessere" Alternative zu etablieren. - Mai 2022: Nvidia veröffentlicht die "GPU Open-Source Kernel Modules", welche die "sensiblen" Teile des Nvidia-Kernel-Treibers in einen geschlossenen RISC-V-Prozessor auf Hardware-Seite (genannt GPU System Processor, kurz GSP) verschieben und es Nvidia ermöglichen, nur die Kommunikationsschnittstelle für diesen als Open Source zu veröffentlichen. Die Userland-Teile des Treibers (CUDA, OpenGL, Vulkan, DLSS) bleiben weiterhin Closed Source. - August 2023: Der offene Vulkan-Treiber NVK des Nouveau-Projekts wird dem Linux-Grafikstack Mesa hinzugefügt. Dank des Vulkan-basierten OpenGL-Treibers Zink unterstützt Nouveau damit sowohl Vulkan als auch aktuelle OpenGL-Versionen. - Oktober 2023: Nvidia fügt Unterstützung für Gamma Lookup Tables (Gamma LUT) hinzu. - November 2023: Der offene Linux-Kernel-Treiber Nouveau fügt Unterstützung für den GSP hinzu, welcher es ihm zum ersten Mal in fast 10 Jahren erlaubt, die Taktrate auch auf neueren Nvidia GPUs zu verändern und damit einen performanten Einsatz möglich macht. - November 2023: NVK erreicht volle Konformität für Vulkan 1.0. - Februar 2024: NVK erreicht volle Konformität für Vulkan 1.3. about this event: https://cfp.gulas.ch/gpn22/talk/FFJ8QT/

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 for anyone within tech. Awards will be a mix of sincere appreciation of cool things, friendly fun, and criticism of capitalist companies that make tech a much more difficult space to be in than it should be. If the event is popular, I hope to make it an annual thing, but let's see how the first one will work out before deciding anything about that. about this event: https://cfp.gulas.ch/gpn22/talk/KVKVDM/

This talk is a ‘how-to’ or recipe to make your electronic projects look professionally finished. It will cover simple graphic design and small-scale metalwork with hand tools. The emphasis is on the techniques useful for personal making and hobby use. As an example we'll look at how to make a professional-looking bench power supply for general test and experimental use.

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 in it on and off for over 30 years. I started with a cheap Tasco telescope from a catalog company and a 110 film camera glued to the eyepiece - it didn't work well (if at all), but it got me hooked.

EveryWhere is an open source system for creating mesh networks to allow communities to connect with themselves without having to use commercial systems to do so. Inspired by David Graeber's idea of the sustainable activities of play and care, EveryWhere aims to make new rituals around technology that allow the network to exist across generations. In 2022 we convened a group of artists, technologists, designers and activists to start the project. As result of the connections made, we have identified themes and ideas that we will present in this talk. The five themes are Community, Sustainability, Software, Hardware and Creative. Within each of these themes, we've identified four main areas of concern. The purpose of this talk would be to relate our progress up to this point and to galvanise further collaboration with the EMF community. We are a pair of artistic researchers and creative technologists and we care! about this event: https://www.emfcamp.org/schedule/2024/195-everywhere-a-regenerative-mesh-network-for-communities

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. This talk will focus on the design behind the guitar, looking at what you can do with generative design and 3D-printing, how to interface the old and new construction techniques (e.g., mating a walnut body with 3D-printed nylon sides), and how to decide what bits to do with which technique. I'll also show how I achieved this as an amateur maker: the aim is to show the audience that what seems like far-out construction is actually reachable by us mortals thanks to improvements in tooling and 3D-printing services.

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 gelernt – und was es eigentlich im Alltag bedeutet, ADHS zu haben. In diesem Talk möchte ich meine Erfahrungen mit der Odysee der Diagnostik/Behandlung und dem Alltag, mit ADHS zu leben, nahebringen und wie eins daraus das beste macht. Dazu zählen vor allem Hacks, mit denen eins seinen privaten als auch beruflichen Alltag ADHS-freundlicher gestalten kann. about this event: https://cfp.gulas.ch/gpn22/talk/BHHPVL/

Model rocketry is great fun and an excellent way to get young people interested in science and engineering. In 2022 and 2023 I mentored a team of 3 teenagers to enter UKROC, the UK youth rocketry challenge. The team had to design and build a rocket to take a raw egg to 250m and return it to the ground in 45 seconds, without breaking the egg. The team went in 2 years from not knowing much to (spoiler alert) winning UKROC and then the International championship at the Paris Airshow. I will talk about the basics of model rocketry (physics, engineering, legal, financial, safety etc), what is involved in entering UKROC, our experiences and how you can get involved in the next UKROC competition.

A research project that started with the question, 'what was the average person in Britain eating 500 years ago?', and resulted in a rich knowledge base of over 1200 native and naturalised plants with food uses. The vast majority of our modern foods originate overseas, introduced to Britain by colonialism and Victorian exploration, and the global human diet now contains less than 100 plants, with limited biodiversity. Starting from the BSBI's database of native and naturalised plants, over the course of 3+ years I painstakingly reseached each entry for historic, archaeological, or ethnographically documented food uses. This body of ancestral knowledge could help provide local food resilience, reduce the impact of the plants we eat, and better protect food supplies from climate change, pollinator loss and disease. The research is still in its raw form as a giant spreadsheet, so the first part of the talk will focus on the process of research and identification, and some of the trickier questions such as the difference between a food and a medicine, what level of toxicity is tolerable, and how to really define a native plant. The second part will focus on some highlights of the results, including obscure disused vegetables, native things you can still forage, lost recipes for brewed alcohols and psychoactives, vegetables we've bioengineered for edibility, some exciting natural poisions, and addressing whether or not lettuce really exists. about this event: https://www.emfcamp.org/schedule/2024/461-the-edible-native-plant-project

I once accidentally got YouGov to poll whether it should be ‘the data is’ or ‘the data are’. Whether you favour 'are' or 'is', in many ways, data is plural. When we talk about data, we’re talking about different things, contexts, needs, and perspectives. Thinking of ‘data’ as a singular thing brings risks. We always have to set data in a more plural context and can never think about ‘just’ the data. And data we think of as being about us – singular, as individuals – is often about a plurality of others, and its value – to governments and tech companies – is in plurality or aggregate. All of this means we need to rethink our approach to data and take a relational, collective and democratic - a plural, political and human – approach.

I am the creative director and programmer at Hollow Ponds, a videogame development studio. I'm going to briefly show some of our earlier games for context, and then talk about a number of interesting things about the development of our forthcoming game FLOCK - a multiplayer game about exploring a big wild landscape on the back of a giant bird, seeking out strange creatures, and charming them into a big flock.

Why, given that 50% of screenwriters in the silent era were women and that there were quite a few female directors and producers, did women get pushed out of filmmaking and never really come back? What happened in the studio era, and why has nothing changed in all the waves of forward movement since? Why, today, do the number of female directors hover around the 10% mark, even after #MeToo and #TimesUp? Female A-list stars still earn only about half as much as their male counterparts, partly because only about 12% of leading roles go to women. Films made by or for women get smaller budgets, smaller releases and smaller marketing spend than male-made equivalents, and the picture is much, much worse for women of colour. So why is this and how do we change things? And why is Barbie such an important step forward?

We will take a peek behind the scenes at the technology used in performing arts venues in order to asses the cyber security implications and how we can address them. A modern performing arts space is no longer several independent systems providing show elements such as light and sound, but rather an IP network fabric delivering the desired elements flexibly around the venue and sometimes beyond. As a community we have gathered a good understanding of designing reasonably secure networks and protocols I would like to apply this knowledge to the unique demands of a theatre. If you often find yourself distracted by the coordination of the light fixtures rather than the performance this talk is for you. Or may you just like designing networks and learning about interesting protocols. I previously covered Audio over IP in a talk at MCH2022: https://media.ccc.de/v/mch2022-113-audio-networks-and-their-security-implications In the interest of transparency I am partially employed (and was previously fully employed) by Holoplot a professional audio company that principally sells network based loud speakers. I'm also a freelance security consultant. However, I'm doing this talk purely in a personal capacity and all thoughts an opinions expressed are my own not those of any employers, clients, or customers.

Wie funktioniert der Prozess von einer Produktidee über Prototyping, Prüfungen hin zu einem Massenprodukt. Ideen haben wir alle viele und manche sind es wert, daraus ein Produkt zu machen und eine eigene Firma/Startup darum herum zu gründen. Unterwegs gibt es viele Stationen die wichtig sind, teils viel Geld kosten und noch mehr Kosten vermeiden. Ich habe selber mehrere (Elektronik) Produkte erfolgreich von der Idee zur Fertigung gebracht und habe selber immer mehr Spaß an dem Drumherum um die eigentliche Entwicklungsarbeit. about this event: https://cfp.gulas.ch/gpn22/talk/ZYCAVA/

Die elektronische Patientenakte (ePA) ist ein Phantom. Jeder hat eine andere Vorstellung davon. Wie es zu dieser Situation kommen konnte und wie die Digitalisierung im Gesundheitswesen dennoch gelingen kann, darum geht es in meinem Vortrag. Die elektronische Patientenakte (ePA) gilt als die zentrale digitale Anwendung im Gesundheitswesen. Zur Einstimmung präsentiere ich Ihnen alternative Realitäten des Gesundheitswesens und wie politische Fiktionen zu Fakten werden. Danach treffen diese politischen Fakten auf die Alltagsrealität. Dazu nehme ich Sie mit in meine ärztliche Sprechstunde. Ich meine natürlich den Teil, wenn meine ärztliche Patientenbehandlung schon beendet ist und nur noch gerade eben schnell die Daten in die elektronischen Patientenakte (ePA) hochgeladen werden sollen. Im letzten Teil gibt es eine Perspektive, wie die Digitalisierung im Gesundheitswesen über das Konzept der informationellen Gesundheit bzw. der informationelle Erkrankung doch noch gelingen kann. Nein, ich meine nicht die informationelle Selbstbestimmung. An dieser Stelle höre ich dann immer wieder die Frage, kannst Du informationelle Erkrankung noch mal erklären? Das mache ich dann. Vorab nur so viel: Neben dem Digitalanwendungsfall der Corona-Warn-App ist diese Theorie auch nutzbar im Spannungsfeld von Geschlechtsinkongruenz und Geschlechtsdysphorie. Die elektronische Patientenakte (ePA) füllt zukünftig den größten Teil des Gedankenraums dazwischen. Informationelle Erkrankung entsteht, wenn Information von außen auf die Betroffenen lebensverändernd einwirkt. Das hat es schon immer gegeben. Zusammen mit dem Wirkungsverlust von Fakten verlieren wir gerade die Wissenschaft als sozialen Moderationsraum. Muss man das alles zu einer Frage der Gesundheit machen? Nein, muss man nicht, aber wenn sich sonst keiner zuständig sieht, dann schon. Exklusion und Armut machen krank und dann sind wir Ärzte zuständig. Hier geht es um die Verhinderung von Krankheit und vorzeitigem Tod und da sind die Ärzte, als die akademischen Experten für Gesundheit und Krankheit unzweifelhaft gefragt. Gleichzeitig verlagert der Ansatz der bio-psycho-sozio-informationellen Erkrankung, oder kurz der informationellen Erkrankung, Teilaspekte von Krankheit, die heute allein einzelnen Menschen zugeordnet werden, zurück ins soziale System, so wie es die Ottawa-Charta der WHO fordert, um Gesundheit zu befördern. Die Digitalisierung im Gesundheitswesen, kann nur gelingen, wenn konfliktreduziertes Zusammenleben und mehr Gesundheit befördert wird. Die Idee der informationellen Gesundheit macht dies möglich. about this event: https://cfp.gulas.ch/gpn22/talk/98NYLC/

Alchemy is a misunderstood art. From Hellenistic Egypt through to the modern day, the story of alchemical science teaches us about how science has changed in the last 2000 years and how it has stayed the same. The influence of this ancient science resonates through our modern world in scientific theory, misconceptions and popular culture. Learn how ancient alchemists formed accurate predictive models of the material world around them, How the Victorians lied to you and possibly even the secret to making gold.

It's 1975! You need a high-resolution computer display for fine drawings (e.g. CAD diagrams). Memory's EXPENSIVE, processors are slow: what to do? Here's an analog solution to a digital problem: an unusual cathode-ray tube that preserves whatever it draws with no flickering, fading, or any kind of refresh. A brilliant dot sears emerald trails into the screen, rendering intricate line-art without pixels. No need for video memory when the screen itself remembers! It's mesmerising to see this special tube in action; more satisfying still to know how it works. Discover a mechanism Tektronix refined over three decades, growing from palm-sized oscilloscope readouts to 25" computer-lab behemoths. A wreath of electron guns, kilovolt potentials, microscopic cobalt cones, and transparent anodes set the stage for a nonlinear dance of charges that yields visualisations with style --- and we'll unravel its mysteries with animated diagrams. En route we'll visit notable storage tube applications, from early computer memories to 1978's _Battlestar Galactica_. Of course we'll see a real Tektronix terminal at work, too! Computer memory is cheap now: by the mid 1980s, modern displays had advantages storage-tube systems couldn't overcome. Nobody's making them anymore, so check out this talk while old stock still works!

The Post Office Horizon IT Inquiry was established in 2020, led by retired high court judge Sir Wyn Williams, to investigate the “failings which occurred with the Horizon IT system at the Post Office leading to the suspension, termination of subpostmasters’ contracts, prosecution and conviction of subpostmasters”. Transcripts of the inquiry hearings are put online, but only in PDF and text format. This talk will explain my history of scraping and parsing official information, how I have taken these transcripts and converted them into a linkable, searchable, and readable version, how I automatically keep the site up to date, and why I've done this.

About the challenges and delights of designing playful interactive systems with elephants currently living in the UK, featuring elephants with brambles, supersize balls, giant sliders and didgeridoos, being curious, affectionate, playful, apprehensive, bored, wilful, impatient, destructive, muddy, moody and matriarchal. This is an ongoing project, focusing on offering choice and control in elephants’ environments to investigate preferences around audition and design aesthetics. Enrichment goals are to provide interesting cognitive and sensory experiences that encourage the expression of natural behaviours. We’ll consider the why, what and how associated with all of that animal-computer interaction stuff, and invite people to share their thoughts and suggestions - either remotely or subsequently over a cup of tea. Love and respect to the elephants in your life.

Einführung in Webservices mit REST, inklusive historischem Abenteuer in Vorgänger und wie wir REST kaputt machen können (mit Praxisbeispielen!) REST ist die moderne Art, Webapplikationen zu schreiben - sogar Java kann damit umgehen. Representational State Transfer bietet eine Möglichkeit, dass wir nicht nur statische Webseiten anschauen, sondern interagieren können, ohne uns mit Javascript befassen zu müssen (ein Quell der Freude für einen eigenen Talk - oder sieben). Wir schauen uns an, was REST ist und wie wir es verwenden, ohne Einschlafpotential. Die etwas eingestaubte Seife aka Webservices mit SOAP und WSDL schauen wir uns aus historischen Gründen an, genauso wie RPC unter etwas Sonnenschein. Nachdem wir ein Grundverständnis von Historie und Funktionsweise von REST gewonnen haben, finden wir kreative Wege, sie einer unbeabsichtigten Verwendung zuzuführen, die sicherheitsbedenklich sein könnten, garniert mit Beispielen aus der Praxis und den unendlichen Weiten des World Wide Webs. Geeignet zum Einstieg und alle, die ein wenig IT-Archäologie und Software-Forensik hören wollen. about this event: https://cfp.gulas.ch/gpn22/talk/FVCLQX/

Common Code möchte geschrieben werden. Warum nicht mit NeoVim? Die Geschichte von Vi, Vim und NeoVim reicht schon circa 50 Jahre zurück. Wir drehen eine kurze Runde durch die Vergangenheit und schauen uns an, wo das alles herkommt. Dabei wird es einige Überraschungen geben! Außerdem stellt NeoVim moderne Editor-Features bereit. Einige davon sehen wir uns an: - Language Server Protocol Client (für Autocompletion, Refactorings…) - Diagnostics API - Lua API (und die init.lua) - Tree sitter Syntax Parser - Terminal Emulator - Plugin-Ökosystem Es wird passend zum Vortrag noch einen NeoVim Konfig-Workshop geben! about this event: https://cfp.gulas.ch/gpn22/talk/ETE9ZT/

In diesem Vortrag werde ich das Konzept des Software Defined Vehicles (SDV) erörtern, welches aktuell die Automobilindustrie umtreibt, indem es Fahrzeuge durch umfangreiche Software-Integrationen und -Updates hochgradig anpassungsfähig und funktional macht. Wir beleuchten die technologischen Grundlagen, Herausforderungen und zukünftigen Potenziale dieser Paradigmenverschiebung, die von der Vernetzung über die Benutzerschnittstellen bis hin zur Implementierung künstlicher Intelligenz reicht, um die Interaktion zwischen Mensch und Maschine neu zu definieren. Und natürlich spreche ich auch die "Sitzheizung als Abo" an about this event: https://cfp.gulas.ch/gpn22/talk/ZJ7TMZ/

You, Eleanor Shellstrop, are dead. You are in cardiac arrest. Your heart has stopped beating, you have stopped breathing, and medically speaking you have died. Not a great start to your day! But worry not: someone has called 999. This talk is the story of that 999 call. This talk, presented by the CAD & Technical Lead at the London Ambulance Service, will describe everything that happens between dialling 999 and getting to hospital, and all of the technology involved in triaging the call, dispatching the ambulance, and helping patients over the phone before it arrives. This isn't a heartwarming human-interest story from the documentaries — this is the full ins and outs of all the systems, processes, and infrastructure that keeps people safe across a major city every day. We'll explore how we use open data to find exactly where you are, exactly how we decide who gets help quickest and who must wait, and how your phone can help save your life. We'll also look at what happens when it all goes wrong, and how we respond to business continuity incidents — after all, we can't just shut up shop if the system goes down. Expect high-level conversations about medical emergencies, but this talk is suitable for all ages. about this event: https://www.emfcamp.org/schedule/2024/405-how-to-save-a-life

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

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/

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

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
