Being Elliot Carver: How to run your own Cable TV station (or network) (emf2024)

There's nothing good on TV, and streaming curses you with the Paradox of Choice. So why not be Elliot Carver for a day and run your own Cable, satellite or UHF TV station - or even a whole network? With a few low-cost computer boards (Raspberry Pi's work but others are fine too) and video modulators, you can recreate the wonders of 1990s Cable TV in your own home, flat, or living room. I'll also talk about going further and how I recovered and resurrected a General Instrument ACC-4000 headend controller PC and used it to configure a small fleet of cable boxes.

Driving fancy LED panels with commodity hardware (emf2024)

Ever wondered about what's behind large advertising billboards? Interested in pretty blinking lights? Curious about electronics and circuit board design? This talk might be for you! Our hackspace recently got a donation of ~800 LED matrix panels (squares with lots of tiny LEDs on them), with little in the way of documentation. I'll explain how they work, how we got them to light up and display things, and how to make it fast enough to display 30fps video -- all with commodity parts that cost less than 20 pounds. We'll explore the weird and wonderful world of poorly translated datasheets and control software, marvel at the library of weird glitched-out images I ended up with on the road to success, and dive into the strange but extremely useful Programmable I/O block of the RP2040 microcontroller. If the stars align, you'll be able to see everything working on a real demonstration panel, too! Although we'll be going into detail on some bits, this talk should be accessible to most audiences. about this event: https://www.emfcamp.org/schedule/2024/199-driving-fancy-led-panels-with-commodity-hardware

A country you can't put in a box. (emf2024)

A talk about the difficulties of geospatial analysis when the country you are interested is on the edge of the world map. We'll go over some background before showing what happens when you try and draw a box around this country and the issues this causes everyone from blury satellite views to navigation failing. And why it happens. The east and west edge of the classic Eurocentric world map, with the prime meridian down the middle, are both the same place, this causes some interesting effects.

How to get anything from anywhere to anywhere (emf2024)

You have an object / art installation/auction purchase and want it somewhere else? What are the options of getting it there without breaking yourself? This will be a short, hopefully entertaining, overview of transport options, their financial and environmental impact and the time they take. This talk is based on examples of personal experience sending hacky art installations around Europe and the globe. By doing this many questions had to be answered for example: - how big are doors? - why acessability regulayions are great or not? - what fits in an elevator? - how much fits in a van? - what fit’s in a cargo aeroplane? There will be dragons! Along the way we’ll encounter customs officers, new excitement around rules for international road haulage, air freight and how astronomically long container shipping takes.

Thomas the Privatised Tank Engine 30 years on (emf2024)

It has been 30 years since Private Eye released this biting satire of the privatisation of British Rail. Today, the railway system is now part public part private, leaving plenty of confusion for passengers. Who runs your local station? Who sets the rail fares, and who covers your refund? And where the hell does HS1 and HS2 fit into all this? I will take you through how the UK rail organisations are structured, who does and owns what, and how does this affect passengers? - What's the difference between Network Rail and National Rail? - How does split ticketing work? - What did Labour announce in April? And most importantly: Who should I be angry at when I'm crammed in sideways on a delayed Sunday afternoon train to Leeds? No knowledge of the rail industry is required to enjoy this talk, but experts will find it depressing. I may swear, mostly about MPs.

Unlimited Power: An Engineer's Low-Down on Nuclear Fusion Technology (emf2024)

Most technical people hear about fusion power in the news or see it in games and movies, and are familiar with the joke that it's always 20 years away. Beyond this, it's surprisingly rare to find good information beyond the basic physics and the marketing promise of unlimited, clean energy. As an engineer working in the fusion technology sector, I give a primer on how fusion power works, why its benefits are so incredibly tantalising yet hard to achieve, what the latest exciting developments are, and how the UK is a surprising trailblazer. I outline some of the cutting-edge technologies involved in developing fusion power, including superconducting magnets, plasma control using deep learning methods, and hypersonic fuel injection. The audience is also given facts and figures to get a flavour of the unimaginable scale of what is being done: materials at nearly 0K adjacent to plasmas hotter than the cores of stars, gigawatts of power from teaspoons of fuel, magnetic fields multiple times more powerful than MRI machines, and neutron fluxes strong enough to transmute matter in bulk. Coming away from this presentation, the audience will have learned about the fundamentals of nuclear fusion and appreciate the key issues enough to put the marketing and news reports into context. They might even be excited and enthused about what's to come in this quickly growing technology space. about this event: https://www.emfcamp.org/schedule/2024/471-unlimited-power

How to 3D Print A Rocket Engine (emf2024)

A talk about the state of the art with metal 3D printing, and how it can let you make rocket engines much more cheaply and quickly than ever before. I will briefly describe the anatomy of a rocket engine and why the extreme conditions it must endure make designing one hard, and then introduce powder metal 3D printing and how you print an engine. I work for a company in this field, and I will show various images and videos of our engines being fired, as well as the engines themselves so that people can have a look, and some samples with internal cutaways to show the internal structures that 3D printing technology now makes relatively easy. I will also discuss drawbacks and common failure-modes of 3D printing for rocket engines, and talk about where new advances in the field might take us, such as multi-metal prints, hybrid machining, and other exciting technologies. about this event: https://www.emfcamp.org/schedule/2024/131-how-to-3d-print-a-rocket-engine

Explosion in a Tunnel; Understanding Swiss Cheese (emf2024)

The talk takes a deep-dive into the Abbeystead explosion (using pretty much all available sources available on the subject), one of the worst civil engineering disasters in post-war history, through the lens of the HSE investigation. It looks at what the project was for, how it was designed, what went wrong, and why. Swiss cheese is a way of conceptualizing accidents, and the explosion is used so show how this works. Hopefully by the end, everyone will have heard about a facinating case study in bad project management, weird critical infrastructure, and have recieved a safety talk by stealth. about this event: https://www.emfcamp.org/schedule/2024/97-explosion-in-a-tunnel-understanding-swiss-cheese

So You Want To Hack On Rail Data: What's out there, and what can you do with it? (emf2024)

The British rail industry publishes a lot of open data: there's at least 18 distinct data sources, plus the ones I'm forgetting. This'll be a whirlwind tour of most or all of those sources, with a view at helping people who would be interested in playing with train data but don't know where to start. You'll (hopefully) leave with some ideas for what you could build (if you didn't already have some), know what data sources you'd need, and have enough context to understand those sources' documentation. I will assume software experience (ie there'll be slides with JSON, XML, and various less pleasant things) but not rail experience.

Does Robot Wars have a Meta? (emf2024)

Robot Wars is a TV show that inspired a generation of engineers to take up the sport of "Robot Combat", but what drove success in the design of those competing? Looking at some famous matches and designs, this talk will break down the rock-paper-scissors of the sport, and try to provide an understanding of how this can help to educate a new generation of engineers today. Should the sport have a Meta, it will mean certain designs always win out over others - however should it not, then it may suggest it is not the design itself that determines success, but rather ones understanding of design. about this event: https://www.emfcamp.org/schedule/2024/134-does-robot-wars-have-a-meta

Living on the canals of the UK - Lessons from the water (emf2024)

The canals of the UK have undergone transformation from industry to decay to leisure and in recent years to housing. In this talk, we'll go through some of the history of this modern day shanty town along with lessons for any budding boaters considering life on the cut. We'll cover the fundamentals of boat life including legality, work from home challenges, common pitfalls new boaters can face along with everything you need to know if boat life could work for you! about this event: https://www.emfcamp.org/schedule/2024/156-living-on-the-canals-of-the-uk-lessons-from-the-water

Steaming into Sustainability (emf2024)

How do you get several three storey Cornish beam engines, a collection of Grade I listed buildings and a whole network of steam infrastructure on the path towards net zero? This talk is the experience of a volunteer on the practical challenges met whilst helping the London Museum of Water and Steam with several major projects. Expect tales of reverse engineering boiler control system ladder logic, interfacing raspberryPis to 100psi steam lines and working out the water/gas/steam usage to run 200-year old steam water pumps.

Astrophysics for Supervillains (emf2024)

“Could you crash the Moon into the Earth?” “If the Sun explodes, would we all get vaporized?” “What’s the weather like on Mercury?” Discover the answers to these questions (and many more!) at "Astrophysics for Supervillains"! Facts about space are all well and good but discovering that if you threw someone into a black hole, they would be spaghettified – stretched out long and thin before getting squashed smaller than an atom – is truly, fascinatingly gruesome. This quirky space talk will teach children about the solar system, galaxies, the universe, and, most importantly, the answer to the question “Which planet is entirely populated by robots?”. about this event: https://www.emfcamp.org/schedule/2024/428-astrophysics-for-supervillains

Hack The Plan: How I Made a Career out of Not Knowing What I Want To Be When I Grow Up. (emf2024)

"So what do you do?" Everything. ────────── As a kid I couldn't decide what I wanted to be when I grew up. I still can't, but over the past twenty years I've turned that into a superpower. In this talk I'll tell you how I hacked the idea of a standard career and managed to combine skills from different fields and specialties, leading to some unique roles and opportunities. If you love learning and constantly adding new tools to your intellectual toolkit, you’ll find that being a 'nerd of all trades' is not just fun—it’s the best way to live. The only downside? When someone asks "so what do you do" at parties, you'll never quite know what to say!

Don't be evil by accident: algorithmic harms and ethics for technologists (emf2024)

Technologists are wizards. Today, we wield the power to effect changes from a tent, a bedroom or an office the likes of which fifty years ago one might need the power of a small nation-state to accomplish. Having seen these systems from all angles - building the tech, researching digital consent academically, and fighting biased public sector algorithms in the media and the courts - I'm confident that we really haven’t adapted to that reality. In the choices we make in technical practice, we find ourselves paving the road to hell with our good intentions. Most of us aren't trained in ethics, policy or politics - so how do we manage the weighty burden of being responsible for people’s safety? What can we do – both as individuals and as a society as a whole – to try and stop algorithmic harms? And, how do we stop our robots from killing us? about this event: https://www.emfcamp.org/schedule/2024/355-dont-be-evil-by-accident-algorithmic-harms-and-ethics

CERN Technology: Following the White Rabbit down a 27km hole. (emf2024)

How does the most complicated machine in the world work? Why should we pay 16 billion euros to keep some physicists happy with a new toy? What has CERN ever done for us? What happens when you lose control of a beam the size of spaghetti with the energy of a full express train? This talk, delivered by a beam instrumentation engineer at CERN, will introduce CERN and it's accelerator complex, and discuss the technology required to deliver one petabyte of cutting-edge science per day to over 170 research facilities in 36 countries. The talk will also cover some of CERN's open source software and hardware contributions to date, and finally explore their science and technology roadmap for the coming years. about this event: https://www.emfcamp.org/schedule/2024/181-cern-technology-following-the-white-rabbit-down-a-27km-hole

An engineer’s guide to parenthood (emf2024)

A lot has happened at the other end of life since the last EMF camp; pregnancy, birth and adjusting to life with a tiny human. I am an engineer, so when two thin blue lines appeared and I found myself thrown into the chaos of pregnancy and parenthood, I discovered that the best way of dealing with it was to use the engineering approach that was already ingrained in me. “An engineer's guide to parenthood” if you will. Some bits worked (some less so!) and that’s what I want to share with you this year, following on from my 2022 talk, "An engineer's guide to grief".

Bringing Any Super 8 Camera Into The Digital Age (emf2024)

This talk will describe the development process for a digital cartridge to fit any Super 8 home movie camera without any modifications required. There are a huge number of unused 8mm home movie cameras that have been languishing unloved for the last four decades since their owners were seduced by videotape. Many of them are built to a rather high quality, and best of all, they can still be found for not a lot of money. You can still buy the film, and it's a lot of fun shooting a real movie, but it's not cheap. Wouldn't it be great if you could drop in a digital cartridge instead for modern day digital video with a retro feel! This project started in early 2023, and this will be its first outing in front of a live audience.

Warum sind hier Menschen mit Seilen? (gpn22)

Die Grenzen von Diversity: Ist Kink noch Diversity oder nur eine persönliche Vorliebe? Warum sind eigentlich auf Hackerveranstaltungen so oft Menschen mit Seilen? Welche gemeinsamen Wurzeln verbinden queere, hackende und kinky Menschen und was könnten wir von einander lernen? Wir machen einen Ausflug in die eigentümlichen Regeln, Rituale und Etiketten der Kink-Szene, um herauszufinden, was davon für andere Lebensbereiche hilfreich ist. Egal ob klare Kommunikation, Awareness gegenüber Diskriminierung und Übergriffen oder die Suche nach Konsens: Viele der Herausforderungen begegnen uns auch in Projekten oder am Arbeitsplatz. about this event: https://cfp.gulas.ch/gpn22/talk/TMWFJ3/

Cyber Resilience Act - Compliance Risk oder Consumer Respect Act? (gpn22)

Der Cyber Resilience Act (CRA) legt Herstellern von Software und auch Open Source Communities strenge Regeln in Bezug auf IT-Sicherheit ihrer Produkte auf. Dieser Vortrag gibt zunächst einen Überblick über die Ziele und Inhalte dieses Gesetzes. Der Schwerpunkt liegt auf den geforderten technischen und administrativen Regelungen und Verpflichtungen. Es wird erläutert, worauf sich Hersteller, Open Source Communities und Verbraucher einstellen müssen und eingeordnet, wie praktikabel und effektiv die Vorgaben möglicherweise sind. Mit dem CRA hat die EU-Kommission eine Verordnung auf den Weg gebracht, die die IT-Sicherheit von Produkten reguliert, mit der Motivation, die Interessen der Verbraucher zu stärken und die EU insgesamt widerstandsfähiger gegen Cyberangriffe zu machen. Dieses Gesetz legt Anforderungen für "Produkte mit digitalen Elementen" fest. Von Herstellern wird die Erstellung einer Cybersicherheitsrisikobewertung und die Bereitstellung von Sicherheitsupdates verlangt. Bestimmte alltägliche Softwareprodukte, wie Betriebssysteme, Browser und Password-Manager, werden als "wichtige Produkte" eingestuft. Diese werden auf die Einhaltung von grundlegenden IT-Sicherheitsanforderungen überprüft. Auch Open-Source-Software und ihre Communities werden von diesem Gesetz betroffen sein. Es wird gefordert, dass diese eine Cybersicherheitsstrategie vorlegen, welche unter anderem den Umgang mit Schwachstellen regelt. Ein Verstoß gegen die Bestimmungen kann mit bis zu 15 Millionen Euro oder 2,5 % des Weltweiten Jahresumsatzes geahndet werden. Des Weiteren wird die ENISA eine Meldeplattform anbieten, über welche Hersteller Schwachstellen melden. In Hinblick auf die Praktikabilität und Effektivität stellen sich eine Reihe von Fragen, auch sind noch nicht alle Details bekannt, z.B. die Spezifikation von SBOMs. *TL; DR: Neues EU-Gesetz, welches Hersteller verpflichtet (IT-)sicherere Produkte zu entwickeln.* about this event: https://cfp.gulas.ch/gpn22/talk/AUEQH7/

Activism in Games, plus a Hopepunk RPG (Role-Playing Game) (emf2024)

Resistance, systemic change, and our sustainable future can – and must – be playful! To quote the activism artist group Guerilla Girls: “If you can make someone who disagrees with you laugh, you're in their brain, and you can change minds.” The speaker will begin by sharing her journey in social impact games and its landscape, focusing on activism initiatives in games. She will draw examples primarily from the UN’s Playing for the Planet’s Green Game Jam which includes ustwo games’ Monument Valley 2's The Lost Forest. Surveys from the jam reveal how games can spur positive actions in real life. Then we take action -- through play. In this RPG-lite / communal storytelling experience curated by the speaker, a few volunteers will take on special roles to battle a dragon turned to the darkside. We’ll meet in our imaginary tavern and adventure together to save the world! Let’s play and change the world together.

Where is the Art? Pen plotters and the history of computer art (emf2024)

In October 1971, Frieder Nake published an article in Page, the Bulletin of the Computer Arts Society, entitled "There Should Be No Computer Art", making the point that there were more important things for humans to work on together in the late Twentieth Century, than whether or not a computer should be allowed to make "art". In this talk, we'll take a journey together to look at one aspect of computer history - creative technology and art - and the ways in which it has been misunderstood and feared at different points in our shared history and culture. Along the way, you'll also hear about how I accidentally became an artist, after being laid off from my dream job with big tech; the story of building my own pen plotters; and, how you can make your own army of art robots!

Practicalities of being a walking lightshow (emf2024)

Festooning your clothes or costume with lots of glowy lights is fun. Making the glowy lights survive hours or days on end of dancing in sweaty raves or muddy festivals is harder. In this talk I discuss several ways of being a walking lightshow, the unfortunate lessons I learned over years of trying them out in the real world, and some attempts at avoiding these failures in future. [Specifically I will cover: chemiluminescence, electroluminescence, UV reactive materials, LEDs, things to consider when making light-up clothing, surprise 100v shocks and how to avoid them, and how to cheat at syncing to the music.] Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://www.emfcamp.org/schedule/2024/416-practicalities-of-being-a-walking-lightshow

"Jetzt ist es kaputt, aber wenigstens war es gut": Informierte Nutzungsentscheidungen und welchen Beitrag Informatische Bildung dazu leisten kann (gpn22)

"Sag mal, du hast doch Informatik studiert - du kannst mir doch sicher sagen, wie ich meine Fotos am besten back-uppe?", fragt mich meine Tante neulich beim Kaffee. Wärend meine Tante mir ihre utopischen Anforderungen erklärt, und ich Erwartungs-Management betreibe, frage ich mich wie ich in diese Situation gekommen bin. Und schließlich frage ich mich als Person mit Lehramtstudium: "Was müsste ich meiner Tante beibringen, damit ich nicht nochmal in eine solche Situation komme und sie diese Entscheidungen selbst treffen kann?" Diese Frage, wie man Schüler:innen (und meine Tante) dazu befähigen kann, in Zukunft Entscheidungen über die Nutzung digitale Systeme selbstständig und informiert zu treffen möchte ich mich in meinem Vortrag diskutieren. Wir treffen jeden Tag Entscheidungen über die Nutzung von Digitalen Systemen, wie zum Beispiel Instant Messenger, Bezahlmethoden oder VPNs. Um eine solche Entscheidung informiert zu treffen, braucht der:die Entscheidende Wissen über die zur Auswahl stehenden digitalen Systeme im Bezug auf seine:ihre persönlichen Werte. Aber welches Wissen ist das? Und welche Werte kann man in Betracht ziehen? Und wie kann man das Schüler:innen beibringen? In meinem Vortrag möchte ich gemeinsam mit dem Publikum über mögliche Antworten und Beispiele diskutieren und in das Thema aus dem Blickwinkel der Informatik Didaktik einführen. Inhaltlich werde ich in meinem Vortrag darüber reden, was informierte Entscheidungen sind - und was informatische Bildung ist. Dabei werde ich auch auf Konzepte aus der Informatikdidaktik wie dem Dagstuhl Dreieck eingehen und diese einführen. Außerdem werde ich über Möglichkeiten zur Vermittlung sprechen. about this event: https://cfp.gulas.ch/gpn22/talk/8CWDWS/

Flightgear: The world of open source flight simulation (gpn22)

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/

I beg you, please make your own GitHub alternatives! (gpn22)

A case for choosing alternatives to GitHub for your open-source works. Both practical and philosophical. Our thoughts, creations and relationships online are made possible because of large platforms based in Silicon Valley. Let's talk about GitHub. People use it. I mean, that's where everyone else is. Period. End of story. ... Or is it?! The first part dives deep into the rocky history of SourceForge and BitKeeper, which implicitly led to the creation of Git and GitHub, which in turn came with its own set of problems. How does the past correlate to the present? (Recommended speed: 0.75x) The second part talks about the present: GitHub. It is explained how it makes money by hosting open-source projects for free, and its prevalence among open-source developers and professionals, as well as its increasing gamification, vendor lock-in and the real-world impacts it has on open-source projects. Is it really as popular and reliable as you'd think? The third part is about some of the (contrasting) alternatives and efforts to work around the problems caused by the "GitHub model", and what they do differently, and why we need something different than a monoculture. Fossil, Forgejo and SourceHut (as well as very brief mentions of the Friendly Forge Format, forge federation, hosted alternatives to github.com, as well as tiny tools like Tor's Anon-Ticket!) are talked about. Disclaimer: I am involved with Codeberg and Forgejo as a volunteer; I may be a little tiny bit biased. Some of the facts I mention were before I was born, possible signs of peanuts and mild errors - first talk, therefore I'm allowed to make mistakes. :) about this event: https://cfp.gulas.ch/gpn22/talk/WGVZ9W/

Lessons learned Open Sourcing the UK's Covid Tracing App (emf2024)

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.

From Makerspace to Outer Space (emf2024)

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!

Big Data Analysis with SQL (gpn22)

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/

How a Wifi chip works internally (gpn22)

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/

Klimaauswirkungen des Datenschutzes – oder: mit #BingoTechBullshit die Welt zerstören (gpn22)

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/

Molding Sand: Shaping Permissions of Processes (gpn22)

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/

The Role of Media in Impact Campaigns (emf2024)

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

Sind wir schon Wayland: Nvidia Edition (gpn22)

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/

Deutsche Bahn für Dummies (gpn22)

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/

The first Tech Awards Ceremony (gpn22)

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/
