Pulling a shot of espresso sounds so simple - just pump some water through a bed of coffee grounds. But while it sounds simple, many things can go wrong. What ends up in the cup can too easily end up bitter, sour, watery, chalky, harsh, or flat. So how can you be an espresso alchemist, and convert your bitter shots into gold? In this talk, I'll cover the anatomy of what goes on during coffee extraction, and the problems that can lead to bad flavoured coffee. I'll also give a whirlwind tour of the different coffee machines, equipment, and hacks that are designed to make better espresso - both the high-value gadets and the duds. You'll learn how to 'dial in' a shot to prevent it being too sour or bitter, and what steps you can take to maximise deliciousness! about this event: https://www.emfcamp.org/schedule/2024/133-the-coffee-fix-why-its-so-hard-to-pull-a-great-espresso

After accidentally becoming fluent in Morse Code I have waded through a sea of dots and dashes to find THE best word in Morse Code (ok, maybe its just my personal favourite - but I have reasons to back it up!) Of course, as a mathematician, I couldn't leave it there and have also determined what I believe to be the best number in Morse Code too. From steganography to lexical anomalies we explore the delights of this not exactly binary alphabet. You may not have time to learn all of Morse Code, so come and learn the singular most awesome word in Morse instead!

In a world where large language models like GPT and Gemini are becoming more and more ubiquitous, what does this mean for comedy? If computers getting things obviously wrong is a factor in their comedy value, do the improvements in generative AI take us into an uncanny valley where the outputs are realistic enough to no longer be funny? Join our presenters as they each argue the case for one side of the battle between generations from large language models, vs. more naive generation approaches. We’ll explore what makes comedy funny at all, and then drill deeper into why we find content generated by computers so hilarious - often when it’s not trying to be! Throughout the talk we’ll give some examples of humorous computer generated content from past projects - intentional or otherwise. Learn why you shouldn’t join us for dinner when the recipes are auto-generated; see how we abuse state-of-the-art AI safety techniques to make LLMs funnier; and join for a group singalong for some live-generated parody karaoke. about this event: https://www.emfcamp.org/schedule/2024/169-from-haunted-karaoke-to-the-humour-feature

This talk will be a quick look into the methods of psychological manipulation that games and chore apps use make your sessions with them longer and get you to come back regulary. Ever wondered why you just can't put your game down, even though you know you should already be sleeping? Were you terrible at learning languages in school but suddenly excel at it using Duolingo? The reasons for both are probably the same. I will to go into the manipulation strategies that games and chore apps alike utilise and compare them to user hostile design patterns, that I have already talked about in the past. This talk will not tell you how to feel about these tricks, but it will hopefully provide you with the knowledge you need to detect them and make more conscious decisions on if you want to let them work on you. about this event: https://cfp.gulas.ch/gpn22/talk/S3HXXG/

Over the past five decades, the concert & live event industry has undergone a dramatic transformation into a major sector of the economy, with the production playing a pivotal role. Artists and their shows constantly seek the latest lighting & video technology, intricate stage setups, and top-notch audio quality to dazzle fans. Ticket sales are a major revenue stream for Artists, and a high-quality production show, sells tickets. This high level of production is only possible because of an industry full of talented roadies. Behind every arena or stadium show lies a hundreads of engineers tirelessly setting up, operating, and dismantling these elaborate stage setups, often in a new venue, on a daily basis. Long gone are the days of makeshift equipment cobbled together, roadies now navigate highly sophisticated AV control systems supported by intricate network infrastructures. A vast array of specialised hardware caters specifically to live events, engineered to be both flexible for on-the-fly adjustments and durable for daily setup and teardown. Reliability is paramount, with equipment expected to perform flawlessly show after show, never missing a beat. In this talk we are going to take an overview into the world of live event production, shedding light on how roadies consistently deliver stellar performances day in and day out. We'll explore the intricacies of AV networks, offering an insightful overview of the behind-the-scenes magic that brings unforgettable concerts to life.

Welche geheimnisvolle Zutat macht eigentlich einen Haufen elektrischer Bauteile zu einem Computer? Und geht das auch mit unter 1.000.000.000 Transistoren, womöglich sogar für normalsterbliche Menschen verständlich? In diesem Vortrag beantworte ich diese Frage auf ganz praktische Weise: Ich stelle einen selbstgebauten, modularen Relais-Prozessor vor, der (hoffentlich) einfach genug ist, ihn vollständig zu verstehen. Klick-klack auf der Bühne inklusive. Prozessoren sind furchtbar kompliziert. Kein Wunder bei dem, was wir alles von ihnen erwarten, und dann auch noch mehrere Milliarden mal pro Sekunde. Da ist es verständlich, dass sie auf den ersten, und auch auf viele folgende Blicke, absolut unergründlich und quasi magisch erscheinen. Dabei gehört gar nicht so viel dazu, Strom zum Rechnen zu bringen. Schon aus gut 100 Relais lässt sich ein ganz einfacher Prozessor bauen, der dann klein genug ist um ihn vollständig zu verstehen. Einen solchen Prozessor habe ich entwickelt und möchte ihn in diesem Vortrag vorstellen. Es wird um drei Themen gehen: * Welche Grundbausteine brauchen wir, und wie passen sie zusammen? * Wie verschalten wir sie so, dass sie nützliche Instruktionen ausführen können? * Wie kann der Maschinencode Programmierung und Elektronik verbinden? Für den Vortrag sind nur Grundkenntnisse erforderlich. Wer weiß, dass Strom durch Kabel läuft, und dass Computer Befehle ausführen, sollte folgen können.

This talk is about RFID/NFC-based payment systems that are often seen in university mensas or company canteens. You typically pay with the student ID card or you employee badge, which is preloaded with money or linked to you monthly salary. The security of some of these systems is severely broken due to the usage of old and insecure RFID/NFC technologies. We will learn some basics about those insecure RFID/NFC technologies and hear stories of broken systems I've analyzed in the past. about this event: https://cfp.gulas.ch/gpn22/talk/VZFLQB/

Using a fad of the 2010s and the UK's most popular river dweller the Leeds hackspace has combined 2 hoverboard wheels with a shopping trolley to create a monstrosity. Armed with a PA system, rally lights, under glow and 2 car horns it’s the perfect centre of chaos for protests or your ALDI shop. During our presentation, we invite the audience to delve into the fascinating world of motorising random objects and the art of upcycling, along with the myriad challenges we encountered along the way. From designing our own lithium-polymer batteries to countless iterations and rigorous testing, we'll discuss the intricacies of dealing with electromagnetic interference, experimenting with various motor controllers, and even designing our own from scratch. We want people to experience the shenanigans we went through and the fun we had along the way to hopefully get more people into whacky-wheeled…..wehicles. But it's not all talk! We're excited to demonstrate the trolley live, allowing you to experience first-hand the joy and sheer mayhem it brings. Our goal is to inspire you to embark on your own wacky-wheeled adventures, learning from our missteps and benefiting from our advice and tips. No Project is ever truly done lastly we want to look into the future: The intended use cases and how we aim to share our knowledge and plans with the wider community. Our commitment to openness and collaboration means that anyone bold enough to motorise anything around them can benefit from our experiences and insights.

This is a talk about how we combined textiles, electronics and storytelling to provide a platform for people to share experiences. For this project, we wanted to explore more the findings of previous research around the guilt mothers feel when feeding their babies, but in a more creative way. Coming at the project from 3 very different points of expertise, we worked with mums to design and make a touch interactive quilt. We asked mothers of young babies to describe their emotions around feeding, a topic often emotional and controversial, and send a voice clip along with a piece of their baby’s clothing which we stitched together to create a special interactive quilt. The quilt is embedded with electronic touch sensors which activate the clips when the metal buttons of the clothes are touched. By interacting with them you can hear the stories through headphones. All this results in a very intimate and emotional experience that provides a platform for visibility and understanding and we think is a great conversation starter to share stories and create community. The talk will include a timeline of how we created a digitally augmented quilt, and a few thoughts if you want to make one too. It will also include some of our own reflections when working on a project that brings up difficult emotions and sensitive topics. about this event: https://www.emfcamp.org/schedule/2024/34-mothers-g-q-uilt

Combining his deep interest in the biology of hair with generative music systems, Chris will give you a an insight into how he has brought the two fields together. After a chance introduction to an Austrailian biology student in 2022, Chris and Jay have spent the last few years researching the mechanics of hair growth, the structures of Amino Acids and Keratins and the composition of different parts of human hair. They used this research to develop a suite of software tools that use these bio-mechanics as a structure for creating music. Chris will cover: - the biology of hair - generative music systems - implementation in Max/MSP and Ableton Live The talk will end with a brand new piece of music created from a single strand of hair. about this event: https://www.emfcamp.org/schedule/2024/202-making-music-with-hair

Always thought it was expensive to receive signals from Space? In this talk I will go through the simple homebrew antennas and cheap (around £10) receivers that you can use to get such diverse things as weather satellite images, pictures from the ISS, receive telemetry from the orbiting CubeSats, and even begin communicating with the first Amateur Geosynchronous Satellite, QO-100 where you can receive TV pictures from amateurs across the world with a rust old satellite dish and a cheap LNB. It is amazing what you can do with a piece of bent water pipe or a coat hanger!

Internet search results were a toxic hellstew of ads, SEO spam, content farms and misinformation/disinformation even before the arrival of Large Language Models like ChatGPT in 2023. In 2024 nearly half the world’s population votes in elections that will have consequential impacts for key issues like climate change and civil rights, and it’s more important than ever before that search results can be relied upon. This talk will highlight a few ways to put search back in the service of the searcher rather than a handful of global megacorps. We’ll time-travel 30 years to the Internet’s Cambrian Explosion period, before Lycos, AltaVista and BackRub/PageRank, and look how technologies like Really Simple Syndication (RSS) and open source self-hosted meta-search engines like SearXNG can help. And then, demo gods permitting, I’ll show you how this can all come together to put a search engine in every pocket. about this event: https://www.emfcamp.org/schedule/2024/13-lets-party-like-its-1994

Die Bezahlkarte für Geflüchtete kommt. Wir haben uns die drei weitverbreitesten Anbieter der Bezahlkarten genauer angeschaut. Im Rahmen des Vortrages werden Datenschutz- und IT-Sicherheitsmängel in Bezahlkarten-Apps und Webapplikationen für Geflüchtete genauer beschrieben. Durch Meldungen im Rahmen von Responsible Disclosure-Verfahren konnten zahlreiche Mängel im Bereich Datenschutz und IT-Sicherheit verantwortlich aufgedeckt und behoben werden. Nach mehrmonatiger Debatte hat die Ampel-Koalition eine Einigung im Rahmen der sogenannten „Bezahlkarte für Geflüchtete“ erzielt und am 12.04.2024 im Bundestag eine Rechtsgrundlage für die bundeseinheitliche Bezahlkarte für Asylbewerber und Geflüchtete beschlossen. Durch eine Änderung des Asylbewerberleistungsgesetzes soll es zukünftig möglich sein, Leistungen über eine sogenannte Bezahlkarte an Asylbewerber zu vergeben. Die Bezahlkarte ist eine guthabenbasierte Karte mit Debit-Funktion. Einige Gemeinden, Städte und Bundesländer haben bereits vorab Lösungen in dem Bereich eingeführt oder Pilotprojekte durchgeführt. Die Lösungen stammen dabei von verschiedenen Anbietern. Neben einer physischen Karte ist für Asylsuchende ebenfalls die Nutzung einer virtuellen Bezahlkarte im Rahmen von Wallet-Apps möglich. Die Bezahlkarte wird dabei innerhalb einer App auf dem Smartphone gespeichert und kann mittels „mobile Payment“ genutzt werden. Im Rahmen des Vortrages werden Datenschutz- und IT-Sicherheitsmängel in Bezahlkarten-Apps für Geflüchtete genauer beschrieben. about this event: https://cfp.gulas.ch/gpn22/talk/RAMYBJ/

Type theory is the secret sauce that makes a programming language awesome. The more knowledge we can make the compiler aware of, the more we can rely on the compiler. But what is the limit? What if we could take _make bad state unrepresentable_ to the mathematical extreme? What is a proof anyway, can you eat it? Come on a wonderful journey into the land of dependent types, where we try building type-safe SQL queries, and sweeten the deal with our own syntactic sugar. I give a compressed intro and overview of Lean 4, a purely functional, dependently typed programming language and interactive theorem prover. Knowledge of purely functional languages is *not* required. 1. We start from zero. Introduction to Lean 4 syntax, side-by-side with Rust. Sum and product types, `List`, some easy intro examples. 2. _Dependent types_: Example of `Vec`, i.e. lists with statically known length. Dependent pattern matching. 3. _Propositions-as-types_: You can have logical `And` and `Or` in Rust, too! But how do you model forall quantifiers? How do you model `x <= y` in the type system? 4. Playing around with _types as first-class objects_, using heterogenous lists and projections on them as example. You can't pattern match on types themselves, or... can you? 5. _Metaprogramming_: Custom syntax, custom elaborators. Using what we learned to make type-safe SQL queries work, such as (note the absence of string quotes): ``` let dragons : Table Dragon := [...here be dragons...] let dragons2 : Table ?huh? := SELECT name, coins FROM dragons ``` Code samples from slides: https://gist.github.com/Kiiyya/5566f09b2d1af6aa0d85ba01179dcfdb about this event: https://cfp.gulas.ch/gpn22/talk/WWMGVN/

Many people rely on pollen forecasts to know when their allergies are likely to cause trouble. So when the main source of them in Finland scaled back after losing funding, a replacement was needed. Hear about the process of starting at zero knowledge of pollen forecasting, discovering the available models and data, and putting it together to get 3-day forecasts for any location in Europe, as a hobbyist with some help from the Finnish Meteorological Institute. Includes learning about atmospheric science, academic data, coordinate projections, Rust and more.

It sounds easy enough: build a clock that always shows the correct local time, no matter where you take it. Mobile phones can sort-of do this, but they manage by listening to the cell towers, so this won't work everywhere. "Radio controlled" clocks just listen to a low frequency broadcast, there's a few different transmissions across the world but they're incompatible and know nothing of time zones. Desktop computers can use the internet for time, but you still have to tell it what zone you're in. Really, it should be possible to build a clock with nothing more than a GPS receiver, which figures out the time on its own, with no need for internet or cellular connection. It turns out that doing this requires an on-board world atlas, a spherical coordinate point-in-polygon algorithm, and a complete database of offsets and daylight savings rules. I finally created a clock that automatically corrects itself as you carry it across country and timezone borders. The journey to this point was so ridiculously tedious that it borders on the absurd. In this talk I'll run through some of the highlights, and of course no talk about GPS time would be complete without mentioning leap seconds, which cause problems even when they don't happen. about this event: https://www.emfcamp.org/schedule/2024/337-gps-time-leap-seconds-and-a-clock-thats-always-right

Are you secretly a spy and/or passionate about open-source? Maybe you don't trust a cloud-hosted service with your highly classified information, or perhaps you like to build things for yourself. In this light-hearted talk, you will learn how to make a real-time on-device GenAI-powered application that can live transcribe and summarize conversations without internet access, using open-source components. Our journey begins with an introduction to open-source LLMs and the latest trends in running GenAI tools on your own hardware. We will build up our application step-by-step, first creating a live streaming voice-to-text transcription pipeline, then an LLM-based conversation summarization layer, presented within a Streamlit frontend, with conversation summaries sent to a lightweight Django API backend for storage. Here's why this matters: 1️⃣ Cloud-hosted SaaS tools cannot store highly sensitive information. 2️⃣ Good open-source alternatives exist for most GenAI tasks; the more people who use them, the more they will thrive. 3️⃣ Commercial tools will solve for common use cases, but developers can build personalised tools that are highly specialised for their own bespoke needs. This talk is tailored for Python enthusiasts and requires no ML expertise. By seeing a practical demo come together piece by piece, attendees will gain a deeper understanding of how to build their own complex Generative AI applications and be pushed to imagine what they could make for themselves using on-device computation in real-world scenarios. Expect plenty of Python code and some fun live demos, with GitHub code provided for attendees to try it at home.

Caves present a challenging environment to survey and map. Conditions are often wet, muddy and involve confined spaces. This talk will look at how the technology we have developed has changed how we measure and create maps of cave systems. From traditional sighting compasses, tape measures and paper and pencil, to laser measures, bluetooth data transfer and PDAs or mobile phones as recording and drawing devices. Then once the data is collected underground, how open source software has been developed by cavers to process the data and draw maps which adjust to later changes in positions of parts of the cave when more data is collected or corrected. We'll look at loop closures, explorations of places no person has gone before, and different ways to present a 3 dimensional map of a 70km cave system. There will be plenty of photographs and video clips of cave exploration, along with live software demos and viewing of digital maps.

It turns out that building a Hackspace in a rural area is really hard. From the name of the group causing security concerns to finding a venue and members, a lot of the challenges that are presented in rural environments don't really seem to be present in the cities where hackspaces are most frequently found.

At EMF 2022 I ran a drop in sewing workshop. Whilst it was popular, one question that I didn't have time to answer properly was the broad: "I want to make my own clothes: where do I start?" I'd like to answer just that question in this talk. I'll cover things like: tools/equipment you need (and what you don't!), how to read a sewing pattern, key things to remember and suggestions for easy projects to get started with. I've previously worked costuming for theatre and designing/making wedding dresses. Whilst my main focus has been on garment sewing, I'm happy to help people with their wild projects: how to make your projects waterproof, how to make wacky shapes and how to work with weird fabrics are all things I can help with.
