What’s the secret to lasting friendships? How does queer community show up through the ebbs and flows of life? And what’s the REAL story behind the “YMCA” song? In the first episode of Silver Linings, The Old Gays dive into an essential part of queer life: chosen family. They discuss the vital love, support, and sense of belonging that community provides, especially during life's toughest moments. They open up about what “queer” means to them, how chosen family has impacted their lives, and how to maintain close bonds over time–including their love for each other! “We’ve come a long way, baby.” Family isn’t just what you’re born with; it’s the people who show up, shape you, and stick around.

How one guy in his bedroom (kind of) beat all of PNG's combined multi-decade effort in one year, and why that's strange. For over two decades, PNG has been the state-of-the-art for lossless image compression. But the Quite Okay Image Format is an emerging low-complexity alternative that offers a different perspective on data compression. This is a talk about PNG, JPEG, QOI, and how more complex doesn't always mean better. Also included: lots of juicy data compression nerdery, including many basics, and an unsurprisingly large amount of maths.

Libre Designers and the Software Apocalypse (lgm2025) 29:10

16 hours پیش29:10

29:10

So, is LGM all about libre tools that software developers make that designers and artists use to make creative work … ? At previous LGMs we’ve talked about open-source design feeding back into improving the look, feel and usability of creative software. But what about the tools used to write those tools? Can we link things back another step? Coding environments have barely changed in decades. Yet the complexity of software produced in them has risen exponentially. The disconnect from cause to effect has become ever greater. All software has bugs, most bugs involve software doing exactly what it was told to do. Sometimes they eat your work, sometimes they kill people. The title of this talk is partly “borrowed” from an article that appeared in The Atlantic in 2017. But is it all hyperbole? This talk was originally proposed for the cancelled LGM in 2020 - the landscape may have evolved since then, such as in the growth of AI, but has it improved? Let’s consider some of the issues. And ongoing experiments in user interaction, liveness and design in various open-source tools that are seeking to change coding for the better. This talk may cover some of the ideas in play. But it certainly won’t have the right answers. It probably hasn’t even found the right questions. But just maybe it’s time to help save the world from code.

From Printer Dust Till Graphics Dawn (lgm2025) 20:07

16 hours پیش20:07

20:07

In this presentation, we partly follow this year's topic "RE:imagination" and will explore old but not old-fashioned printer control languages such as HP-GL (1970s and 1980s) and PostScript (1980s) and device-specific commands for dot matrix printers (1980s) to better understand how we relate to printers and printing today. What can we learn from these languages from current graphic practices and perspectives? What context were these languages developed in? Which aesthetics can be created with them today and which tools are needed to do so? How can the sharing culture of the FLOSS/LGM community be applied to such old "closed source" devices? This artistic, media archeological, and auto-ethnographic research is part of the Master Experimental Publishing (XPUB) in Rotterdam, where we, students and teachers, studied these languages together in the first 3 months of this year on the most obsolete and almost discarded printing devices of our university. Expect a presentation about frustrations with serial connections, dust removal with compressed air, porous plastic that disintegrates into small pieces, glitch aesthetic with PostScript and the practice of working within the obstacles of dying devices. Watch out for undead pen plotters & printers and their obscure languages!

A developer talk about coming up with a new file format for [Drawpile](https://drawpile.net/) with the focus being on the findings and ideas that would be useful for other programs as well. Some of those ideas are already implemented and have brought a massive speedup in file saving and loading, some wilder ideas like continuous autosave with history-altering time-travel are in various states of currently still being worked on, but sufficiently cool to talk about anyway. ## Links * [Drawpile](https://drawpile.net/) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/2882617605/…

Introduction to Usability/UX Evaluation Methods (lgm2025) 27:12

22 hours پیش27:12

27:12

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 as an example of a usability inspection method, and usability testing on the other hand. Both methods can be used to find (potential) usability problems in a software. Whereas a heuristic evaluation is conducted by an expert following a check-list, a usability test needs end users who fulfill tasks to be conducted. After describing how both methods can be used individually, also a practical way to combining them is presented. The session will conclude with an overview of the advantages and disadvantages of each method. ### Three takeaways of this session will be: * A basic awareness for usability/UX and the importance of evaluating it * An overview of the two major usability/UX evaluation methods heuristic evaluation and usability testing * A first idea how to use these methods for your/a software project ## Target group * UX/usability laymen * Contributors to software Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/4264988911/…

Making Waterfalls (lgm2025) 21:11

23 hours پیش21:11

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

23 hours پیش20:18

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

1 day پیش20:17

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

1 day پیش21:59

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

1 day پیش22:23

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

۳ روز پیش23:04

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

۳ روز پیش22:04

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

۳ روز پیش18:01

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.
