The Apollo Guidance Computer (AGC) was a critical element in the success of the Apollo Moon landing programme, and was one of the first digital computers to use the then new technology of integrated circuits. By modern standards, its design has many unusual aspects, such as: - The logic circuits were made entirely from 3 input NOR gates. - Design was split into 24 logic modules, but due to limits...

simpledrm is a fbdev replacement implemented in the DRM kernel subsystem. It allows for smoother handover from the early boot phase to when a "real" DRM driver is loaded. In addition it allows for Wayland support on simple display adapters that do not have their own DRM driver. It has already been mainlined for a while but is not in active use by major linux distributions. In this talk I will brie...

Keysmashes are way of expressing emotions through spamming random letters on a keyboard but what do they actually mean? How random is a keysmash? Where do keysmashes come from? What can we learn about a person from their keysmashes? This talk is a beginners guide to the world of keysmashes and what they tell us about modern communications and online communities. about this event: https://c3voc.de

I am an engineer, so when my partner died when I was 24 and I found myself in the midst of grief, I discovered that the best way of dealing with it was to use the engineering approach that was already ingrained in me. “An engineer's guide to grief” if you will. Some bits worked (some less so!) and that’s what I want to share with you, ahead of a honest, open conversation exploring how we can get a...

We have several ways to install and update openSUSE distributions, standard with zypper, atomic with transactional-update or using disk images created with kiwi or similar tools. But this are all RPM based. In some scenarios, it would be good to have an image based installation and update mechanism (image means /usr, not a full disk image). A PoC is MicroOS TIU (https://github.com/thkukuk/tiu), wh...

Business processes evolve continuously, customer expectations and requirements change even faster. Process management and workflow support systems have a tendency to grow organically into fearsomely complex monolithic beasts while piling up technical debt in the process. Data migrations come at high cost, changing systems almost always require data to be converted into the new systems particular d...

Exploring data ethics through creative immersive tools with brainwave, and motion capture data. Is there a difference in sense of self (identity) between the human and the virtual? How does sharing your personal biometric data make you feel? How can biometric and immersive development tools be used in the computing classroom and dance studios to raise awareness of data ethics and immersive perform...

The SEGA Dreamcast was released nearly 25 years ago, but was discontinued after only 18 months on sale in the west, and was such a commercial failure that SEGA never made another console. Despite this short lifetime, a homebrew community formed, has not gone away, and has only become more passionate since. The most tangible demonstrations of this passion are the extensive hardware modifications th...

Trains are one of the safest ways to travel, but it hasn't always been like that. In this talk I will introduce the basics of railway signalling, and look at how it has evolved over time - often in response to accidents and near-misses. You will find out how a single stray wire caused an accident that killed 35 people, why leaves on the line cause such a problem for the railways, and how signallin...

Default community distributions are running in the same issues for special architectures. Every Linux distribution has got mostly separate maintainers and hardware distributors are handling these communities really often disconnected. That has been identified also for the architecture s390x. Therefore, openSUSE, Fedora, Debian, SUSE, Canonical (Ubuntu) and Red Hat have established together with IB...

D-Installer is the code-name of a experimental project for creating a new YAST-based installer designed to offer reusability, better integration with third-party tools and the possibility of building rich user interfaces over it. In this talk, we will explain the motivation of the YaST Team for creating a new installer and what possibilities this new idea brings. There will be time for diving into...

Margate, Kent is a phoenix rising from the ashes of Britain's great seaside institutions. This one-time jewel had been abandoned to decay and deprivation. The last 6 or 7 years have seen green shoots of regeneration begun by Turner Contemporary Gallery and is now rich in galleries, media consultants, music and film producers. Its High Street is an exemplar for retail re-purposing. Unfortunately, t...

Fire has been a ubiquitous technology for countless millennia, finding applications across many problem domains. This talk describes the development of a new product that brings fire into the wearable technology arena. Wearable technology is often limited to daily practicalities like reading emails on your wrist or tracking your fitness goals. In this talk you will witness large plumes of burning...

Unfortunately, you cannot pop magic Limitless style pills to improve your memory. But with a bit of understanding about how our memory works, we can introduce techniques that will help us remember important and even unimportant information. In this talk, I will talk a bit about the structure of memory and then discuss some techniques that anyone can use to improve their memory (when you want to)....

**transactional-update** is the openSUSE way of a **Transactional Operating System update** and a core component of _openSUSE MicroOS_ / _Kubic_ and _SLE Micro_, making sure updates can be applied safely without affecting the currently running system. It's also supposed to play an important component in the future ALP. At lot of things have changed internally since the last talk at oSC19: The core...

Sourcery is a program that builds root file systems consisting mostly of Go source code: of the 90,000 files in a typical sourcery root, there are only 12 or so programs. Other programs are compiled on demand to a ramfs-backed file system. Compilation takes a fraction of a second for most programs, and never more than 2 seconds. Once the program is compiled to a statically-linked, tmpfs-based bina...

Suzie is the creator of Two Tin Cans, a printmaking studio in a telephone box which will be at EMF! Two Tin Cans is a K6 style phonebox... with a difference! Inside the phonebox is a tiny printmaking studio includes printing blocks created by Suzie Devey. Every person who enters the box can make a unique work of art to keep, for free. New artwork is created for every event making the work highly c...

Just how effective are solar panels and domestic batteries? Here's several years of *real* data from UK-based solar panels. Can you generate *all* the electricity which your home will consume? What happens to the electricity you sell to your neighbours? Do they work during a powercut? Will I have to change my lifestyle significantly? Is winter a problem? How long do they take to install? Where can...

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 e...

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 alw...

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 hopefull...

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 a...

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 hackat...
