Advances in NLP and machine learning are allowing automatic processing of knowledge. An untapped potential of this revolution is the ability to change how people come up with ideas and solve problems. People tend to solve problems in linear ways. If my horse is too slow, I want a way to make it faster. It wasn't clear to many people of the 1800s that changes in industrialisation would lead to an entirely new way of going fast! So what happens when you do have all of the information, and when you can find subtle patterns occurring in vast swathes of data? What happens when an engineer's Alexa can tell you not just the answer to your question, but the answer to the question that you didn’t know you were asking? I would like to explore how AI may fundamentally change the human’s ability to think and invent, and the changes that this may lead to in society, drawing on my experience as the head of the world’s first AI augmented invention team with example patents and progress that has been made so far. about this event: https://c3voc.de

Pretty much everything that has ever been designed is some form of balance between form and function, from modified car's to architecture to clothes and even user interfaces. In the modern age of material design, Visual Design Group's and Human Interface Guidelines this balance has very much shifted to be in favor of function over form, an interface that looks good is still important but looks always seem to play a distant second to usability. The purpose of this talk is to explore what happens when you flip that idea and rather then focusing on creating user interfaces that are primarily usable instead focus on creating user interfaces that are works of art with a lesser regard as to how easy they are to use. Fortunately this idea is nothing new, in the late 90's Raster founded the enlightenment desktop inspired by the artistic user interfaces of the games he played growing up, he brought these concepts to the desktop. The advancement of graphics hardware in the mid two thousands lead us to the world of fish tanks inside cubes, wobbly windows and painting fire on the screen. Not because there was any real need or use but because someone could. Sadly since then the world of the Linux desktop has tried to go all professional and many of the fun interesting things have been lost.

As a psychologist, I often get asked one of two questions: Can you read my mind? Are you analysing me?* But Psychology is not entirely useless; by studying the mind and brain, we can learn a lot about how we work. In this talk, I will go through some psychological party tricks and tell us about how we understand the world around us. Some of these mind tricks have been around for ages, but hopefully, they will make for an interesting (even fun) way to pass the time and present an opportunity to learn about yourself. *(The answers are No and No - Unless you pay me a lot of money to retrain as a therapist.) about this event: https://c3voc.de

I am the captain of a BattleBots team, currently showing on Discovery Channel in the US and streaming worldwide. Among the many engineering challenges we face building combat robots, material selection is critical. I don't only mean choosing steel over aluminum, I mean choosing which kind of steel to use for each application on the bot. In my talk I will cover the basic material science of steel alloys, hardening processes, and how they are used to build combat robots and other industrial applications (and what happens when you make the wrong choice). about this event: https://c3voc.de

Back at Electromagnetic Field 2016, I talked about something that was starting to get wider media attention: an up-close-and-personal glimpse of the future involving sex, tech, AI and robots. I then returned in 2018 to debunk the headline myths and update on what was actually happening on the tech side. Now it's 2022 and it's been one heck of a ride. That original talk launched two sex tech hackathons, saw the UK host a conference, produced a book, and – nicest of all – contributed to the growth of a global community researching these things. There’s a few new things happening in the arena — but also very little progress on the hardware front. Why is that? What’s the actual likelihood of domestic bliss with a hot machine (other than your toaster) by 2050? This is third talk in the trilogy! about this event: https://c3voc.de

Tales in a life of a product security engineer making Open Source software more secure one bit at time. In this session, I will talk about what does it mean to be a product security engineer and how SUSE security team audits can help Open Source community in having a better security posture.

When a 3,500 ton ship tries to be in the same place as an oil rig then it is safe to say that someone is going to have a bad day. Nobody was injured and no oil was spilled, so it didn't make the news and was just an insurance job - a very BIG insurance job. This talk explains the many mistakes that led to the accident occurring, and how much worse the outcome could have been. It is presented by an insider, but only uses information in the accident report and other public sources for legal reasons :) about this event: https://c3voc.de

Before downloading a software release, we all know to verify the GPG signature before even trying to unpack that tarball. And when such a signature is not available, we all know to chastise the developer for not taking security seriously. But what happens with deployed web resources? How can these be verified before we trust them with our secure data? I would like to show a proof-of-concept of using out-of-band verification (aka, DNS) of web content (.js, .html, .jpeg, etc) prior to allowing it to execute and trusting it with our data.

A short talk on how to build, play and perform with a ukulele illustrated with geeky songs based on my love of physics and electronics. Advice for joining bands and getting free beer at a pub open mic night for the musically inept. I'll bring along my homemade electro uke made out of oak, enamel paint, and bruised thumbs. Although the talk will be brief, I can stay around afterwards to discuss cutting frets, changing strings, stage fright and how to stop your fingers from freezing when playing outdoors in December. about this event: https://c3voc.de

During the last years, the openSUSE infrastructure was improved a lot. But is it perfect now? Of course not - otherwise the Heroes would be bored, and I could not give this talk.

This talk explores the softer side of electronics, from electronic embroidery and e-textiles to soft robotics and flexible PCB design. We will take a look at some of the exciting technologies in this field, including industrial machines that embroider traces to microcontrollers, open source soft robotics, 'pick and place' sewable LEDs, e-textiles in space, fabric speakers and the world of flexible and stretchable PCB design. I will also share examples of how engineers, scientists and artists are using these soft electronics technologies in their work. As well as this higher level overview, we will take a look at a number of accessible DIY projects, along with practical tips on materials and techniques, and suggestions for further learning. I will also talk about softness in electronics in a non-literal sense, looking at some cool projects from the community that link emotions, vulnerability and physical computing. about this event: https://c3voc.de

Sudo is used by millions to control and log administrator access to systems, but using only the default configuration, there are plenty of blind spots. Using the latest features in sudo lets you watch some functions that previously were blind spots and you can also control access to them. There were several minor and major changes since the 1.9.0 release that I discussed in my previous FOSDEM talks.

Deploying images is ever evolving topic. Although much of the deployments today are concerned with containers, base systems for container host are somehow needed to be deployed as well. Let me present Saltboot, part of Uyuni stack. Saltboot is building on SaltStack to make image deployment secure and together with Uyuni provides complete image lifecycle and management - from image building, staging to deployment on target machines.

A deep dive into the Windows boot process, its security mechanisms, and the security issues that have been found within the last 10 years, culminating in a single bug (found in August 2021, fixed in January 2022) that can bypass all such security mechanisms. about this event: https://c3voc.de

About four years ago I realised I was miserable and that I should probably do something about that, so I did what any self-respecting nerd would do and read a tonne of books to figure out how emotions worked (I did also go to therapy, but the books were more useful). Life isn't perfect now, but it's a lot better despite the ongoing war and pandemic. I'm going to give you an overview of some of the things I've learned. It will be a mix of theory (what even are emotions?) and practical advice for understanding and engaging with your emotions better, with a pointer towards further reading that will help you act on this advice better. about this event: https://c3voc.de

I run Parkrun (some weeks), and am trying to run the alphabet. While running one week I realised that every parkrun course is the same. They are all basically one of a few mathematical objects, the integers or some pair, tuple or quadruple of integers. We will ask and see why? In this talk I will explore the broad and interesting idea of Topology and present them to a general audience through comedy and one of my other main passions, parkrun. I will use homotopy and related ideas to show how everyday objects and familiar activities are the same to mathematicians and explain why, think coffee cup and donut. about this event: https://c3voc.de

Games controllers are boring. They have the same few buttons in the same place. It doesn't have to be this way. In this talk, I'll go through how I've made controllers that are different and unique. These controllers are quick and easy to make with a microcontroller and Circuit Python, and theycan use almost any input device, such as slider potentiometers, rotary encoders, IMUs and touch pads. We’ll look at what’s worked, what hasn’t and how to make your own games controller. about this event: https://c3voc.de

The Open Build Service has new support to allow developing packages directly in git repositories. This means that entire source management would be handed over to some pagure, gitlab or gerrit instance as origin of trust. The talk will describe possible setups, workflows and development scenarios. Including an open discussion what should we aim for our main distributions.

An introduction to getting started designing and building your own audio DSP processors for guitar pedals, eurorack modules and other similar style projects using modern microcontrollers. Covering the very basics of digital audio, microcontrollers, audio codecs and PCB design, this talk will give a whistle stop tour of the process involved in making digital effects processors from conception to building a prototype. This talk will be aimed at those with little experience, but an interest in combining electronics and programming to process live audio in hardware. I came from a programming background, and have no training in electronics. I want to show an audience what can be achieved with a little bit of knowledge and lots of enthusiasm. Encouraging borrowing from open source projects to identify common circuits and practises that can be stitched together to form a complete project. about this event: https://c3voc.de

Imagine this: you're a Venezuelan student activist, and you're protesting to get your university the budget it so desperately needs and the powers that be mercilessly cut away. But then, your government disrupts phone coverage in the area to discourage protestors and potentially cover human rights violations. Scary, right? Hopefully you're not in this situation. But chances are your hacker brain would love to know how I used tech to react to this! In this talk, I'll cover how we stayed connected using Mesh Networking, phones' Wi-Fi chips, a couple of apps, a bit of fear, and a whole lot of determination! https://twitter.com/gustakasn0v about this event: https://c3voc.de

openSUSE Leap Micro is a new distribution based on SUSE Linux Enterprise Micro with the main purpose to be a host-os with minimal footprint which fits well the app-centric world. A small foot print, focus on the EDGE as well as data center, containerization and virtual machines, whatever flies your app. Leap Micro has a 6 months release cycle with support lasting until the next release or up to 4 years of support with a migration to SLE Micro. openSUSE Leap Micro is a new distribution based on SUSE Linux Enterprise Micro with the main purpose to be a host-os with minimal footprint which fits well the app-centric world.

Delighted to announce that the Ore-Some Xylophone will be making its UK debut at EMF 2022! Come and see the electromechanical xylophone that generates truly random compositions by measuring the radioactivity of a lump of uranium ore. You can turn the handwheel to move the lead shield and adjust the speed of the music. I like making things, often mechanical or electronic. My sculptures frequently have audio elements, and involve owls whenever possible. My website has a lot of descriptions of how projects were built, but I'm planning a talk that gives a little more detail about the business side of making things full time for a living. The talk is aimed at myself, 20 years ago. I hope you're listening, younger me... about this event: https://c3voc.de
