The speaker works for a small company in the UK who have developed a VTVL (Vertical Take-off, Vertical Landing) rocket, also known as a hopper or lander. This started as a student / hobby project and is now receiving funding from the European Space Agency (ESA.) There are lots of interesting technical problems involved in making a VTVL rocket work. You need to steer the rocket engine and control its thrust based on data from a variety of sensors. This involves mechanical, electronics and coding challenges. When fully developed, the test vehicle we've developed will be used to test software and hardware that enable robots to land safely on other planets such as Mars.

The talk will start with an introduction to rocket engines and a simple explanation of the vehicle's dynamics then cover the development of our VTVL rocket from hobby project to successful flying test-bed. It will include video footage of recent test flights where the rocket takes off and hovers on a tethered test rig.

PAMAL_Group is a European artistic group, composed of artists, media theorists, curators-restorers and engineers.

Their artwork "3615 Love" will be installed at EMF 2022.

PAMAL_Group creates its own works from digital artworks that have disappeared or been severely damaged due to the obsolescence of computer software and hardware. Its work seeks to reveal the vulnerability of an art that is highly dependent on industrial logic. All the artworks that the collective reconstructs, as close as possible to the original materialities, sometimes in a deficient way, are treated as archives.

The artwork "3615 Love" is based on the reconstruction of telematic materialities (videotex, Minitel network, etc.) and the archive of works by Jacques-Elie Chabert and Camille Philibert (L'Objet perdu, 1985) and Eduardo Kac (Videotext Poems, 1985-1986). The installation "3615 Love" shows how fragile and vulnerable our digital environment - and a fortiori its artistic productions - is.

We've all found ourself doomscrolling, and fighting against social network's barrage of extra things in our newsfeed and notifications to keep us there for longer. It's not good use of time, energy and mental bandwith, and hell in my case the habitual refreshing has started giving me RSI.

I'll go through my three steps to stop Doomscrolling and get out of the social media refresh loop (or at least try to).

It's no news or secret that containers are good at providing multiple and different testing environments, or at offering a way of deploying apps and services that are completely decoupled from the host OS. E.g., spin up a distro X container, check if code compiles there (and dispose of it).

How about the opposite? I.e., having one (or more!) stateful and persistent environment(s), tightly coupled with the host and sharing as much information and configuration as possible with it. Why? Well for running that one app, which is only available for another distro, with just a click on a desktop launcher icon. Or for doing all kind of experiments, inside our development environment, without risking the stability and the consistency of the system. Well, yes, containers can do these things too. And in openSUSE, we have both toolbox and distrobox, that can make these examples, just reality!

In this talk, we'll explain what they are and how to use them for spawning development and application environments, based either on the same distro you have on the host or on different ones, and inside of which you still have all your file. A working space that, despite being containerized, you can access seamlessly from within GNOME Builder or open new terminals directly inside of it and create launcher icons for apps installed in there.

We'll offer (more) examples and show how this can be very useful, both on immutable (like MicroOS) and on "traditional" (like Tumbleweed) systems.

YaST, the flagship installer and configuration tool of openSUSE is in

constant development. Just as its unattended companion AutoYaST.

Although the YaST Team at SUSE tries to communicate progress as often as

possible in the YaST Blog, it has been almost two years since we

presented the "Top 25 New Features in (Auto)YaST" at openSUSE Conference

2020. So it's time for another live update!

We will recap the main changes and new features that are already

integrated into openSUSE Tumbleweed and that will be included at

openSUSE Leap 15.4, to be released just a couple of days after the talk.

We will also take a look to some ideas for future development... and we

really need the feedback of the whole openSUSE community for that. So

please join us and speak up!

The largest and the highest energy scientific device - the Large Hadron Collider (LHC) is currently in operation at CERN.

This machine is unique in many respects:

- It is the most powerful microscope, which can probe the distance one million times smaller than the size of the proton

- It can reproduce conditions of the hot Early Universe with the temperature billion times higher than in the core of the sun, corresponding to a picosecond after the Big Bang

This uniqueness gives the LHC opportunity to resolve the biggest puzzles of the Universe:

- to find the origin of Matter-Antimatter asymmetry – the origin of planets and starts

- to Shed a light on the origin of Dark Matter and Dark Energy, 95% of which the Universe is

made of (stars and planets contribute only 5% to it !)

- to give us the answer on what is the ultimate theory which drives this Universe – at micro and

macro scales.

In the presentation I will explain the exciting details of the Large Hadron Collider and how it helps to solve the most challenging problems of particle physics and cosmology – from micro to macro scales.

AutoYaST is the main method for installing openSUSE Linux in enterprise environments. Although it is usual for AutoYaST to get new features and fixes with every minor release, openSUSE Leap 15.3 was special in that regard. Thanks to the "Modernizing AutoYaST" initiative, we introduced relevant features like ERB templates, better validation tools, etc.

However, we have found that many of these features remain unknown to our users, and the openSUSE Conference offers an excellent chance to present them.

We take a scenic tour through the origins of the UK train ticket, from the original BR specification in the 1980s through to modern replacements like mTickets, eTickets and ITSO.

This is just a detour though, and we'll focus on the 'orange ticket' (RSP 9399/9599) - which continues to be a stalwart of the UK rail network. Surely they can't be that secure? After all, anyone can encode a magstripe - right?

We'll take a look through the data encoded on these tickets, what interesting things you can do with them and maybe (assuming I've got it working by then) we'll be able to read and write our own!
