Get ready to take a trip into space. We'll be travelling 400km up to the International Space Station, to take a look at Earth through the lens of the Astro Pi computers that were sent there in 2020. This talk will focus on what has been learnt from years of giving young people the chance to take photos from the ISS using affordable commercial hardware. There will be plenty of the amazing images th...

With the speed of 400G coherent technology was introduced to pluggable optical transceivers (OIF 400ZR and OpenZR+). This technology is complex and powerful for your network, it even has influence on your network device operating system. This talk will provide first insight in Nokia's implementation as well as known or potential interoperability issues addressed by the OIForum. If your transport s...

You become aware of a security vulnerability affecting your Go program(s)! What now? This talk tries to answer that question for various common scenarios, explaining the roles of the various technologies and services (like the Go Module Proxy or Go Checksum Database). The recent xz vulnerability brought the topic of Supply Chain Security to everyone’s attention. I don’t have a solution for prevent...

Federated Learning (FL) offers a privacy-preserving machine learning method by enabling collaborative model training across multiple clients without data sharing, securing sensitive information at its source. This talk explores Machine Learning applications and how to keep them secure, for example in critical sectors like healthcare. Collaborative learning, and in particular Federated Learning (FL...

This talk is about our delight, awe and fear of electricity and its effects on the human body. It charts our changing relationship with it from the 18th century to today. I particularly love the 18th century gentlemen scientists with their electrical entertainments - particularly because they appreciated the magic of electriocity and were so excited by it. Its sad that people today just take elect...

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 extra...

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...

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 t...

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...

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-qualit...

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 inse...

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 vollstä...

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 rando...

A rare live two way link with the Boulby Underground Laboratory, where the Boulby team will give us a tour of the underground facilities that include a Mars Yard, where real (and LEGO) Mars rovers are tested, multiple Dark Matter research experiments, understanding the radioactivity of substances and more! Have any questions you want answered? Email them to will.furnell@stfc.ac.uk Boulby is one of...

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...

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 par...

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 rec...

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...

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-Sicherh...

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 ty...

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 hob...

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 zone...

Graphite kombiniert Vektor (svg) und pixelbasierte Arbeitsweisen in einer FOSS Grafik-Design Software. Das Node-basierte Bearbeiten erlaubt nicht destruktive Workflows und die prozedurale Generierung von Kunst. In diesem Talk werfen wir ein Blick unter die Haube und ich gebe ein Einblick, warum wir dafür eine eigene Programmiersprache entwickeln und was man damit Cooles anstellen kann. https://gra...
