Der regionale Zweckverband für Umwelt- und Naturschutz SIAS in Luxemburg (https://www.sias.lu/) plant Naturschutzmaßnahmen für seine 21 Mitgliedsgemeinden und begleitet deren Umsetzung. Die 16 Mitarbeiter des SIAS führen dabei z.B. Kartierungen des Großen Feuerfalters (Tagfalter) durch oder planen das Anlegen von Streuobstwiesen. Wie sie dabei von Open Source GIS-Software unterstützt werden, soll in diesem Vortrag erläutert werden. Im luxemburgischen regionalen Zweckverband für Umwelt- und Naturschutz SIAS hat sich die Anzahl der Mitgliedsgemeinden in den letzten 15 Jahren mehr als verdreifacht und die Anzahl der Mitarbeiter in den letzten fünf Jahren mehr als verdoppelt. Mit diesem Wachstum haben sowohl die Menge als auch die Vielfalt der Aufgaben stark zugenommen, was bei den Mitarbeitern zu dem Wunsch geführt hat eine Datenbank aufzubauen, um Informationen einfacher austauschen und Maßnahmen besser koordinieren zu können. Im Jahr 2022 wurde diese Aufgabe von den Mitarbeitern selbst gestartet. Dazu wurde nach dem Prinzip „Learning by Doing“ eine PostgreSQL-PostGIS-Datenbank sowie ein WebGIS zur einfachen Bearbeitung der Daten mit dem Webclient Lizmap aufgebaut. Inzwischen werden etwa 1600 Flächen, auf welchen der SIAS Maßnahmen umsetzt, über die Datenbank verwaltet. Dazu zählen das Pflanzen von Obstbäumen und Hecken, die Pflege von Streuobstwiesen oder das Anlegen von Gewässerrandstreifen. Auch für die Kartierung gefährdeter Tier- und Pflanzenarten wird die Datenbank genutzt, zum Beispiel für die Kartierung des Großen Feuerfalters auf ca. 300 Flächen. Im Vortrag wird u.a. auf die folgenden Punkte eingegangen: das komfortable Vorbereiten der Karten für das WebGIS mit dem QGIS-Plugin Lizmap oder die Nützlichkeit des engen Austauschs zwischen Nutzern der Anwendungen (PostgreSQL-PostGIS Datenbank, Lizmap WebGIS) und dem internen Management dieser Anwendungen (z.B. Erweiterung von Dropdown-Listen im WebGIS, Anpassen von Trigger-Funktionen der Datenbank). In der Zukunft würden wir gerne eine aktuell genutzte proprietäre Software zum Erstellen einer weiteren Web-Anwendung durch Open Source Software ersetzen und sind dazu sehr an Ideen zu möglichen Open Source Alternativen der FOSSGIS Besucher interessiert.

Making Waterfalls (lgm2025) 21:11

לפני 3 hours21:11

21:11

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 various methods to cheat so that you don't really have to know complex math to make something acceptable.

Re:Imagining a 3D and Interactive Internet (lgm2025) 20:18

לפני 4 hours20:18

20:18

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 gtlf exporter, the Behavior Graph. It enables interactivity via node-based logic and is only available in Blender 3D. It is the very feature we would like to present to you. If you are used to Blender’s nodes graphs, you might feel right at home. However managing interactivity creates a distinct difference, since every node needs to get triggered by events, be it player interaction or just timer based. ![BehaviorGraph Logo Illustration](https://libregraphicsmeeting.org/2025/img/events/re-imagining_3D_interactive_internet-BehaviorGraph.png) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/3725599921/…

Hyper 8 Video System (lgm2025) 20:17

לפני 20 hours20:17

20:17

[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 nothing more than a terminal, file explorer and text editor (or both). Due to their static nature, Hyper 8 sites are inherently fast, maintenance-free, long-term archivable (also working offline without a server, directly off disk) and compatible with pretty much every webhost (thereby easy to publish and move). In this talk I want to take you on a whirlwind tour around the project: Who is this for? What was the motivation? How does this relate to PeerTube? What is being developed at the moment? Where is it going in the future? What are the challenges, learnings, anecdotes so far? And so on. And of course also: Your questions! ## Links * [Hyper 8 Video System](https://simonrepp.com/hyper8) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/1785153121/…

The PDF Toolbox (lgm2025) 21:59

לפני 20 hours21:59

21:59

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 everyday outcomes and be sure our PDF will match the delivery standards, using only free softwares? In this presentation, we will talk about several PDF tools trying to reach this goal of giving the right PDF to the right person.

PCB Artwork with KiCAD (lgm2025) 22:23

לפני 21 hours22:23

22:23

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 expression, a lot of them actually using KiCAD for the design work. I want to showcase examples of PCBs where the properties of PCBs are used to create visually appealing hardware. I'll also give a quick tour through KiCAD to show the limits of its capabilities as well as its strong side for graphical artworks.

A View on the Open-Source Video Editing Landscape (lgm2025) 23:04

לפני יומיים23:04

23:04

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-source options? What does it even take to build software like this from scratch, technologically as well as mentally? This talk takes a brief look at the free-to-use options for video editing on a desktop computer before switching the perspective to that of the developers and maintainers of such software. It offers insights into the struggles with technology, fundraising, self-motivation, and community dynamics, while also highlighting the rewarding moments and intriguing current and future developments.

Permacomputing: Fermenting Regenerative Aesthetics (lgm2025) 22:04

לפני יומיים22:04

22:04

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 development, but it also holds a great potential as part of a shift in imagination to new practices and aesthetics that are more verdant, just and humane. This presentation will propose the concept of "Permacomputing" as a useful lens to consider the role of FLOSS in developing alternative practices. Permacomputing is both a concept and a community of practice oriented around issues of resilience and regenerativity in computer and network technology inspired by permaculture. We will start with a brief introduction to the concepts and emerging projects around these ideas. With these notions in mind, we can then examine how some of the existing practices of Libre Graphics might inspire or give relevant support to newer, more holistic ways of working. And finally, we will look at some specific examples of software development, education and image making using the generative flora of computing within limits.

The Curious Case of Splines in FreeCAD (lgm2025) 18:01

לפני יומיים18:01

18:01

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 NURBS can also cause a good amount of confusion, especially compared to other representations of splines, which may be more familiar to the user from other applications (which may include other CAE apps as well as more artistic tools like Inkscape). In this talk, I discuss some of these common questions often seen in the issue tracker and forums, as well as best practices to follow for common workflows. I also showcase current progress and future plans to make the experience more intuitive and in line with other apps.

Let's All Go Back To Bitmap Fonts! (lgm2025) 21:52

לפני יומיים21:52

21:52

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 for convenient usage in modern free-software applications. The first scenario is enabling vintage computing aesthetics in graphic design: there are several paths available to transform bitmap fonts into forms usable in Inkscape, GIMP, and other open-source design tools. The second scenario is getting text onto inexpensive LCD, LED, and OLED display hardware. Most such display hardware allows the runtime loading or flashing of bitmap characters, but pitfalls abound. Options and recommendations for both scenarios will be examined, with demos drawn from vintage arcade fonts and the classic Xorg/X11 font suite. To conclude, the talk will outline the licensing issues likely to arise when dealing with bitmap font packages that so often predate contemporary free-software licenses.

UpStage (lgm2025) 29:18

לפני יומיים29:18

29:18

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 technologies. The last time we presented UpStage at LGM, in 2021, we had just begun this process; since then, the new platform has been launched and development is ongoing. In this presentation, our Lead Developer Gloria W. and UpStage Persister Helen Varley Jamieson will present the new platform and its features including its integration of Jitsi for audio-visual streams, audience interaction and live text and drawing tools. Most recently the developers have implemented Docker and made other improvements to the backend, to make installation of independent instances easier and testing more automated. Alongside the development work, UpStage continues to actively promote the use of open source tools by artists, and the involvement of artists in the development of our digital tools. This is ever more important as LLM (so-called AI) and the increasing hegemony of proprietary social and creative platforms force artists into their paradigms. UpStage continues to be an independent, artist-led space for the “RE:imagination” of better worlds. ## Links * [UpStage](https://upstage.org.nz/) * [UpStage: the cyberformance platform](https://upstage.live/) * [Mobilise/Demobilise](https://mobilise-demobilise.eu/) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/1998122706/…

The State of Processing: How We’re Bringing a Creative Coding Icon Back to Life (lgm2025) 21:17

לפני יומיים21:17

21:17

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 Processing code written twenty years ago still runs in Processing today with only minor changes. That kind of longevity is rare in software and speaks to the project's thoughtful design. But behind the scenes, the project has been struggling. For a long time, Processing relied on a small, dedicated core team. As contributors moved on, fewer people remained who understood the full complexity of the codebase. Maintenance became harder. Key libraries stopped working. By the time Processing 4 was released, the project was already in a difficult place. In 2021, a major fundraiser for Processing’s 20th anniversary brought unprecedented financial support, but it also sparked difficult conversations about the project’s future. In 2023, Processing’s historical maintainer, Ben Fry, cut ties with the project, and with no clear direction, development stalled for over a year. Many assumed Processing was dead. It is not. That same support that brought uncertainty also made recovery possible. Over the past year, a small group of contributors, with support from the Processing Foundation, has restarted development, modernized infrastructure, and begun the slow, difficult work of making Processing a sustainable open-source project again. Processing will turn 25 in 2026, and we’re working to make it last for another 25 years! This talk is an honest look at what it takes to keep a beloved open-source project alive, the progress we’ve made, and why the community’s role in its future is more critical than ever.
