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/schedul...

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 (spoil...

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...

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 dat...

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...

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 #Ti...

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. A...

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 erfol...

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 Realitäte...

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 mod...

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 p...

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....

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 elephan...

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 befasse...

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...

Wir beleuchten die technologischen Grundlagen, Herausforderungen und zukünftigen Potenziale dieser Paradigmenverschiebung, die von der Vernetz...

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 d...

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 a...

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.em...

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 m...

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, vie...

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 b...

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 righ...
