Wie kommen Code, Grafik und Musik in einer Demo zusammen? Wie läuft eine Demoparty ab? Und vor allem: Wie kann man da mitmachen? Eine Starthilfe für Neugierige, inklusive Tipps und Tools. Die Demoszene schafft seit 40 Jahren echtzeitgerenderte Computeranimationen am Rande des technisch Machbaren. Egal ob auf einem C64 oder in aktuellen Browsern. Mit eigenen Riten, Methoden und Subkulturen hat sich daraus eine ganz eigene digitale Kulturform geschaffen. Wir schauen uns in diesem Vortrag an wie die Demoszene heute aussieht, werfen einen Blick auf die diversen Möglichkeiten wie man sich daran beteiligen kann und gehen einmal Schritt für Schritt durch, wie ihr eure eigene Grafik, Musik, 3D Model oder Demo in eine Competition auf einer Demoparty einreicht. about this event: https://cfp.gulas.ch/gpn22/talk/9EJPGZ/

*Mastodon lässt sich ganz schnell aufsetzen*, haben sie gesagt. Was sie nicht erwähnt haben: den Aufwand, den die Moderation so mit sich bringen kann. Ein Einblick in die Moderation, Administration und die Lektionen, die ich daraus gelernt habe. about this event: https://cfp.gulas.ch/gpn22/talk/WKPJFE/

A short session for even shorter talks Language: English or German -- english -- Wanna say something? The stage is yours. You have 10 minutes to talk about anything. A short talk about the aerodynamics of ducks; promoting your new open-source project; a small hack that you found; social commentary ... anything goes. Available infrastructure: A microphone, beamer and laptop with a USB-Stick to show slides (PDF format). If you want to use your own device to show your presentation, please come to the stage 15 minutes before the event so we can test the setup.

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.

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/2024/521-girls-just-wanna-play-games-and-be-represented-in-them

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.

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.

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

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.

The bicycle wheel is quite possibly the best thing humans have ever invented. But then, I would say that - I build them for a living. Come along for a quick ride through their creation, evolution and revolution, a detour through some weird and wonderful designs and maybe a look at what a high-tech future holds for this deceptively simple structure. about this event: https://www.emfcamp.org/schedule/2024/116-cobwebs-snowflakes-and-crows-feet

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.

Join us for a calendrical safari of the weird and wonderful history of Calendar Systems and Movable Feasts. Marvel, as we compute the date of Pancake Day. Gasp, as we gaze on the metric madness of the French Republican calendar. Find out why on earth, the UK tax year starts on April 6th?!

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.

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/

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/

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
