Im Schutzraum der ärztlichen Sprechstunde, erfahren Ärzte privateste Sachverhalte von ihren Patienten, die sie durch ihre Sprechstundendokumentation in sensible Daten verwandeln. Die Telematik bedroht die Privatheit dieser Gesundheitsdaten, während gleichzeitig die DSGVO nicht schützt. Viele Stunden Arbeit und sehr, sehr viele Blatt Papier verbraucht die DSGVO, seit sie mit großem Getöse Pfarrbüro...

Die Revolution vom 9. November 1918 beendete den Ersten Weltkrieg, in dessen Verlauf 10 Millionen Menschen starben. Auf der einen – hellen – Seite brachte die Revolution ein demokratisches Deutschland mit einer modernen Verfassung hervor. Diese beinhaltete ein gleiches Wahlrecht, das erstmals Frauen die politische Teilhabe ermöglichte. Die Monarchie war nunmehr Geschichte. Es herrschte Freiheit fü...

"Less computation implies faster code": Sounds reasonable at a first glance, but a closer inspection considering memory or disk latency numbers of modern computer architectures quickly reveals this to be a fallacy. In this talk I will discuss some ballpark latency numbers every programmer should know and hint at implications for designing algorithms in the context of high-performance computing as...

Der Vortrag stellt dar, was Deepfakes sind, wie diese hergestellt werden und welche Auswirkungen sie auf die IT Security haben können. Böswillige Aktivitäten, die durch menschliche Interaktionen erreicht werden, sind heutzutage alltäglich. Angreifer verlassen sich auf psychologische Manipulationen (Social Engineering) und bringen Benutzer dazu, Sicherheitsfehler zu machen oder vertrauliche Informa...

Speaker: Siegfried Kärcher Title: "Meine Zeit als kreatives Mitglied der Computerszene von Amiga-Zeiten...

Fairness and accountability are important topics for decision makers, but formulating these in a rigid, mathematical context can be hard. We'll be looking at implicit and explicit biases, how they arise in data and how they are learned by modern sytems, different notions of the word "fair" and the way biases can leak through obfuscation. Everybody is talking about machine learning and artificial i...

Sprengstoff war und ist ein aktuelles Thema in der Community, zu dem ein wenig Hintergrundwissen nicht schaden kann. Insofern ist eine chemische Betrachtung der Thematik mit Wissenschaft (Science!) ganz hilfreich. In Zeiten, in denen simple chemischen Formeln (H2O2!, CO2!, NaHCO3!) schon eine gewisse Bedrohlichkeit, Angst und in Kombination mit Modellen aus einem 3D-Drucker zu dem Verdacht führen,...

FSK 16+ In meinem Vortrag zeige ich, wie moderne Yachten aufgebaut sind, welche Systeme an Bord zur Navigation und Steuerung eingesetzt werden und wie diese miteinander interagieren. Anhand von 2 verwundbaren System mit...

People coming from other languages can find a lot of familiar aspects in Rust’s traits: Traits are somewhat like interfaces, and also somewhat like type classes, and also like… classes? This talk will try to give you an overview of what traits are and how you can use them to make your code more concise and flexible. about this event: https://c3voc.de

This talk explains how you can use the Fn* traits to properly accept functions and closures as function parameters, and gives an overview of which closures implement which traits. about this event: https://c3voc.de

I’ll take some time to explain what is Wayland and why it’s here to stay. Then, I’ll give a high level overview of the state of Rust on Wayland: how to write servers and clients, and how far along we can get with Rust. I want to focus on Smithay projects, and wlroots-rs. about this event: https://c3voc.de

Nobel-prize winning Professor Richard Feynman is known not only for his dramatic contributions to theoretical physics, his teaching of physics and his testimony on the Challenger disaster, but also for his unconventional life. Noted for picking locks, questioning authority, and unapologetic playing of bongos, the physics superstar also dabbled in life drawing and testified to the acceptability of...

Members of the EMF infrastructure teams (network, power, video, telephony) will give some insight into how we delivered these services this year. We'll explain particularly some of the new challenges faced at Eastnor, and the new services we've delivered, along with sharing some statistics on how they were used. This year we'll also talk about some of the automation we've developed over the last f...

I hacked a domestic knitting machine from the 1980s and turned it into a network printer. I'll show you how I did it using a Raspberry Pi, an Arduino compatible board, Python and a PHP/MySQL web interface. I share my source code. I'll also take you through a brief showcase of what I've done with my printer since automating it, including Stargazing: a knitted tapestry on show for the first time her...

I'm James, and I'm responsible for firing literally hundreds of billions of (low power) laser pulses at the countryside in the UK through my work at Gigaclear, a rural FTTH ISP. We're using mobile mapping technologies to make better maps of the country for our network planners. In this talk I'll provide an overview of Mobile Mapping technologies, precision location (and the technology to achieve i...

Making is cool, but we talk and think a lot less about maintenance. Everything we make - software, hardware, communities - needs to be looked after, if it is useful. Sadly, maintaining, repairing and sustaining can be challenging in a fast-moving era, where this work can be seen as boring and low value, compared to the excitement around inventing or making new things. It is easy to forget that app...

Contemporary software engineering is at a crucial juncture in the evolution as a discipline. We’re professionalising and expanding our abilities, but in doing so we’re encountering dramatic new risks and venturing into new ethical territory. In this way, we share similarities with the expansion of traditional civil engineering during the industrial revolution. In this talk I’ll discuss what lesson...

I've designed a series of PCB modules that can be wired in series to form wearable circuits: necklaces, bracelets, or even epaulets and other accessories. Each small PCB has solderable pads for large SMD or through-hole components – including LEDs, resistors, coin battery holders, and so forth. Each holds one component, except for a few which are decorative (such as LED diffusers), and I plan to e...

How can classical ballet be used a medium for computer science theory, digital ethics and visualisation biometric data including EEG? What will the future hold for the human body and communication when we boldly go into space? What ethical consideration must we take to ensure that it is the many who control their personal data? We’ve been making educational, technologically exciting ballets and pe...

Its difficult to say how many mountains in the world have never been climbed - probably thousands. Breaking new ground is always exciting, whether in mountaineering or mathematics. We'll talk about our experiences making several first ascents of unclimbed peaks in the Indian Himalaya and the Kyrgyz Tien Shan, and some of the surprising similarities to our other lives in research and development. W...

Orbs are located all over the site, hung in lots of locations (aiming for 30). Players use an RFID card to capture the orb for their team, changing the orbs colour. A website shows which team hold which orbs and tracks who is winning, with a live scoreboard in the null sector. This talk is a breakdown of how it all works, the orbs themselves and the game architecture. The hardware inside the orbs,...

Everyone has visited a hacker conference, but not many have seen it through the eyes of an organizer. As someone who has worked hard behind the scenes to make SHA2017 one of the more awesome events, I am giving you a firsthand experience on the good, the bad and the ugly of event organisation. about this event: https://c3voc.de
