The session will start with an introduction to the topic of usability and user experience (UX), including the human centered design process (HCD) and design thinking (DT). After having laid out the foundation, a brief overview of different usability evaluation methods is given. The main part of the presentation is about introducing two often used methods: On the one hand the heuristic evaluation a...

Come learn about some ways to create waterfalls for video games! Inspired by a variety of waterfalls in the Pacific Northwest of the USA, Tom has been playing around with different ways to create waterfalls in the open source Godot game engine, with the help of other open source software such as Blender, Krita, and Gimp. Video game fluid flow is a complex subject, and this talk will outline variou...

Hubs is an open-source interactive browser based 3D meeting space. It is now fully integrated in Blender 3D, which is using an extended version of the gltf format. An extension allows you to attach all the basic components to objects, like particles, UV animations, water and much more. But you can also share links, videos and audio right inside your 3D rooms. Soon another feature was added to the...

[Hyper 8](https://simonrepp.com/hyper8) is a static site generator for video, developed since 2023 and first released in 2024. It uses a file-based, modular building block system for authoring video sites ranging from single videos, to playlists, to video collections of arbitrary hierarchical complexity. Sites can be created and edited using Hyper 8's graphical user interface, but also using nothi...

It is well known that PDF has become a very popular file format. Everyone use it everyday for many purposes. In this context, many software can produce PDF. Still, as graphic designers, we must often deal with provided PDF that doesn’t match our needs, because one PDF isn’t worth another. On the other side, printshops also come with their own standards and constraints. How can we deal with theses...

At the 2014 edition of LGM in Leipzig I've shown the evolution on printed circuit board design with a special focus on fonts, which were mostly constrained by the technical capabilities of the tools available at that time. Ten years later, however, there now is a strong Free Software option for designing your own PCBs and there is a growing community of artists using PCBs as a medium for artistic...

Whether it is stitching together some travel footage or producing high-quality film content, there are many ways people want to work with the medium "video". Their needs for video editing solutions are diverse, and so is their budget. Open-source video editing software seems great for beginners to get started at zero cost. What do you get and what do you have to give up on compared to the closed-s...

Images created with digital graphic techniques have played a central role in promoting the seemingly endless growth of a computing culture that many of us now recognize as extractive, polluting and exploitative. Beyond that, something that once promised a utopian future now feels like it has delivered a rather crappy, disappointing reality. FLOSS has undoubtedly played some role in this developmen...

Splines, especially in their general form as NURBS, are an extremely versatile tool in a 3D designer's kit. They allow the designer to succinctly and efficiently model objects of arbitrary shape and smoothness. For converting these designs into physical objects, FreeCAD has a vast set of tools to operate on NURBS, both as planar curves and (with addons) as surfaces. However, the complications of N...

Scalable vector fonts have been the norm for decades, but that doesn't mean artists and hackers don't have use cases where a bitmap font fits the bill (and it doesn't mean that classic bitmap font designs deserve to be forgotten, either). This session explores two distinct scenarios where bitmap fonts have a role to play and looks at the tooling needed to convert or repackage older bitmap formats...

UpStage, the artist-led platform for cyberformance (live online performance), celebrated its 20 th anniversary in 2024 along with the completion of the four-year Creative Europe funded artistic project Mobilise/Demobilise. This project enabled a complete “RE:imagination” of the UpStage code, removing its dependency on Flash, introducing new features and bringing it up to date with current technolo...

Processing is one of the most widely used open-source tools for creative coding and CS education. Since it was first released in 2001, it has been instrumental in teaching coding to students, artists, and designers worldwide, serving as a gateway into programming for people who might never have touched code otherwise. A remarkable thing about Processing is the consistency of its API. Most Processi...

We're kicking of this years special focus -- RE:imagination -- exploring the possible futures of the Libre Graphics Meeting. ## TODO: Keynote? This may be a placeholder for a keynote, that still needs to be determined. ## Special focus – RE:imagination The Libre Graphics Meeting faced significant challenges during and after the pandemic.

Zur Lage der Bürger- und Menschenrechte in Deutschland Am Dienstag, den 23. Mai 2023 um 10 Uhr wurde in Berlin der neue Grundrechte-Report vorgestellt. In seinen 38 Beiträgen zeigt der alternative Verfassungsschutzbericht erneut auf, wie Gesetzgebung, Verwaltung und Behörden, aber auch Gerichte und Privatunternehmen die demokratischen und freiheitlichen Grundlagen unserer Gesellschaft gefährden. L...

Das Schweizer Gesundheitswesen ist geprägt von IT-Lösungen. Mangelnde Interoperabilität reduziert jedoch ihren Mehrwert, erhöht den administrativen Aufwand und verhindert den überfälligen Fortschritt. So kommt es, dass Daten aus der täglichen Behandlung anderer Patienten ungenutzt bleiben. Am Netzpolitischen Abend vom 22. Mai 2025 sind Fabian Vollrath und Stephanie Künzli zu Gast. Er ist Mitgründe...

_„Ah, dieses Problem ist mir schonmal begegnet!“_, schreit das Hirn. Aber was war die Lösung dafür nochmal? Wo genau ist es aufgetreten? Da gab es doch super hilfreiche Dokumentation zu – aber wo liegt die? Notizen zu machen und wiederzufinden, ist vielen von uns einfach zu viel Aufwand. Doch es gibt Werkzeug, das es die Arbeit wert macht. --- In diesem Talk stelle ich **Obsidian** als Markdown-No...

Voraussetzung für ein Clusterfuck ist erstmal ein Cluster. In diesem Talk betrachten wir grundlegend wie Kubernetes aufgebaut ist, und wie man damit seine Docker-Probleme hochskalieren kann.

Wie funktionieren eigentlich Netzwerk per Glasfaser? Was will man beachten, wenn man damit arbeitet? Welche Fasern, Transceiver und Stecker braucht man? Was kann schief gehen und wie debuggt man das?

Bluesky ist ein recht neues dezentrales soziales Netzwerk, bei welchem es unter anderem die Möglichkeit gibt, eigene Algorithmen (Feeds genannt) zu erstellen. Diese lassen sich veröffentlichen und dann von allen anderen Usern auf der Plattform nutzen. Ich arbeite an einem Open-Source Tool welches die Erstellung solcher Algorithmen durch einen visuellen Editor sehr einsteigerfreundlich gestaltet, a...
