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.

Angesichts der wachsenden politischen Einflussnahme auf große IT-Konzerne wird der Ruf nach alternativen digitalen Infrastrukturen lauter. Mitglieder des Grazer Kulturservers mur.at laden zur Paneldiskussion: was ist die Gegenwart & Zukunft selbstorganisierter nichtkommerzieller Serverprojekte? Und was braucht es vielleicht, um mehr als "nur Alternative" zu sein? Die wachsende politische Einflussnahme auf große amerikanische IT-Konzerne und Medienplattformen wie Facebook und Instagram zeigt drastisch die Abhängigkeit von kommerziellen Serviceanbietern in Europa auf. Es wächst der Ruf nach Alternativen, wie auch die Kritik am Modell der kommerziellen profitorientierten IT. Was sind nichtkommerzielle Organisationsformen für IT-Services und Social Media? Was können wir tun, um selbstverwaltete digitale Infrastrukturen zu stärken oder noch resilienter zu machen? mur.at, eine der ältesten FOSS-Serverprojekte und Netzkunstplattformen in Österreich, lädt Künstler:innen und Aktivist:innen zu diesem Thema zur Panel-Diskussion ein. Neben Mitgliedern des mur.at-Teams nehmen Vertreter:innen von servus.at (Linz) und der Wikimedia Foundation an der Diskussion teil. Ziel der Paneldiskussion ist der Wissensaustausch und die Vernetzung von Interessierten und Aktiven in freien, nichtkommerziellen FOSS-Serverbetrieben und Kulturserverprojekten.

Machine embroidery is becoming increasingly popular. It is more durable than other customization methods for textiles and it adds a whole new artistic dimension to the design. What makes it so beautiful, also adds a new layer of complexity to the machine embroidery design creation process. In this brief introduction we will learn a few basic essentials on how to create machine embroidery designs using the Open Source vector graphic software Inkscape along with the Ink/Stitch extension. ## Links * [Ink/Stitch](https://inkstitch.org/) * [Inkscape](https://inkscape.org/) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/2052117469/…

Printing Maps with Spot Colors (lgm2025) 31:20

לפני 20 hours31:20

31:20

… using Qgis and Scribus with a little help from Inkscape, and Ghostscript. ### A happy-ending story about finding out the tips and tricks along the way. Last November, we've been comissioned to produce a small series of printed maps for a cultural center in Lessines, Belgium, to celebrate memories of Louis Scutenaire and René Magritte. We aimed for a project using three colors, and decided to go for spot color printing - using libre graphics tools, mainly QGIS for the design of the map, and Scribus for layout elements and to prepare the pdfs for printing. We also used Inkscape to vectorize some small illustrations, as well as Ghostscript to check and sometimes fix the resulting PDFs. Then, once we decided that it would be spot color printing, we had to find out a workflow from QGIS to Scribus in order to produce PDFs for spot-color printing. It was not without a few obstacles that we encountered, as both QGIS and Scribus present limitations in terms of color processing or vector rendering. We will present our productive investigation into both QGIS and Scribus, describe how we use QGIS functionalities to optimize the maps for spot color printing and show the tips and tricks we learned along the way - and share the results, hoping to inspire other mapmakers around to give it a try. ![A](https://libregraphicsmeeting.org/2025/img/events/printing_maps_with_spot_colors-feYCQ39ktaCeaGSR.png) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/1308567759/…

TypeRoof is **type tooling infrastructure**. It provides type proofing applications, initially based on Video Proof and Variable Type Tools. Now it also explores the world of general animation with type as a principal actor, and document creation with general typography in mind and typographical automations based on expert knowledge. TypeRoof is **intended as a host** for all kinds of type related tools, providing advanced methods of resource loading (i.e. fonts, data files) saving and restoring state etc. – features which ad-hoc developed tools typically miss out, as they are hard to do right on limited time. TypeRoof is **Free/Libre Open Source Software and web based**, build mainly with vanilla JavaScript and a few specialized dependencies. We are looking for a community of users and developers who are interested in shaping its future. ## Links * [website: TypeRoof](https://fontbureau.github.io/TypeRoof/docs/) * [git](https://github.com/FontBureau/TypeRoof) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/622685393/…

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

לפני 1 day29:10

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

לפני 1 day20:07

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!

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

לפני יומיים27:12

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/…

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

לפני יומיים20:18

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

[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

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.

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

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 4 ימים22:04

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 4 ימים18:01

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 4 ימים21:52

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

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 4 ימים21:17

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.

Your Thoughts in a Graph: Structured Notetaking mit Obsidian (fsck2025) 20:36

_„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-Notizen-Editor vor. Ein wertvolles Tool, das Notizen eine bessere Darstellungsform gibt, als die Baumstruktur eines Dateisystems. Alles ohne proprietäre Datenformate, auf der lokalen Festplatte. Eine Verlängerung des Hirns auf den Computer. 🧠 Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://cfp.ctbk.de/fsck-2025/talk/YWJW9T/…

Einfach Offene Bluesky Feeds bauen (fsck2025) 46:21

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, allerdings trotzdem auch umfangreiche fortgeschrittene Funktionen bietet sowie die Möglichkeit, den Feed mit einer eigens konzipierten Sprache zu definieren. Im Talk wird es um all das gehen, mit dem Ziel nach dem Talk selber komplexe Feeds erstellen zu können :) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://cfp.ctbk.de/fsck-2025/talk/Z3Y7WG/…

Milan Meets PipeWire: Deterministic Audio Streaming for everyone (fsck2025) 16:37

לפני 21 ימים16:37

16:37

Time-Sensitive Networking (TSN) is transforming industries like automation and automotive, ensuring the reliable and deterministic transmission of data. Within this world of TSN, there is a specialized flavor of Audio-Video Bridging (AVB) called the Milan protocol. While Milan is designed to guarantee deterministic, high-quality audio delivery, the Open Source community's efforts in this space have stagnated in recent years. This talk will provide a high-level overview of TSN and the Milan protocol, before diving into the exciting, ongoing work to integrate Milan compatibility into pipewire-avb. We’ll explore the challenges we’ve faced so far, the quirky hurdles encountered, and what still lies ahead in making full Milan functionality a reality. Whether you're involved in the open-source community or simply curious about how Milan can revolutionize audio networking, this talk will offer a fresh perspective on the journey toward making Milan open and accessible for all.

In diesem Talk nehmen wir euch mit, auf unsere spannende Reise, OpenWrt über die originale Ruckus-Firmware auf ZF7363-APs zu flashen. Erlaubt ist dabei ausschließlich die Verwendung des LAN-Ports, da die Ziel-APs an der Decke eines Lagers hängen und die UART-Schnittstelle auf dem Mainboard somit nicht sinnvoll zugänglich ist. Da bisher nur eine Flashmethode per UART bekannt war, mussten wir uns einen komplett neuen Weg reverse-engineeren. Dabei gibt es viel zu lernen: Man stößt auf die Internet Checksum, legacy scp, base64 und noch vieles mehr.

IT Fails in Österreich. Ein Update. (glt25) 48:53

Die Jahre 2020 bis 2025 haben ja, nicht zuletzt durch die zum Teil überraschenden Herausforderungen ad-hoc zu erstellende Anmeldelösungen, zu "interessanten" IT Fails geführt. Unvergessen ja auch das Erfolgskapitel "Kaufhaus Österreich". Für KennerInnen der Szene sicherlich wenig überraschend hat sich aber an der Situation in der österreichischen (Behörden) IT wenig geändert. Immer wieder tauchen "interessante" Meldungen in den Medien auf, die einiger Interpretation bzw. einer Einordnung nach "Digitaler Grundbildung" bedürfen. Geht mit mir auf eine kleine Reise durch die IT-Fails der letzten Jahre und lasst uns schauen, ob/was wir daraus lernen können. Dies ist ein "bring your own popcorn" Vortrag.

systemd's D-Bus Implementation, And Its Python asyncio Binding (glt25) 48:17

לפני 5 weeks48:17

48:17

An overview of D-Bus, systemd, and systemd's own D-Bus implementation, [`sd-bus`](https://0pointer.net/blog/the-new-sd-bus-api-of-systemd.html). Less slide show, more live coding in Python and [`asyncio`](https://docs.python.org/3/library/asyncio.html>). D-Bus is a broker-based interprocess communication mechanism which has been used for ages in Linux's desktop environments like [GNOME](https://www.gnome.org/) or [KDE](https://kde.org/). [systemd](https://systemd.io/), the Linux init system and service manager, likewise consists of many loosely coupled components. Since systemd's inception, likewise, its components are using D-Bus to communicate. Over time, the systemd developers have become uncomfortable with the existing D-Bus implementation they were using. They created another implementation, [sd-bus](https://0pointer.net/blog/the-new-sd-bus-api-of-systemd.html), tailored towards systemd's needs - minimal and fast. This talk gives an overview of D-Bus and its concepts, and then shows how sd-bus is used to implement one's own interfaces and components. Out of its many language bindings, we will use Python to implement a use case, just to show how simple this is. You will probably like the use of [asyncio](https://docs.python.org/3/library/asyncio.html) in the talk. For those of you who don't know what this is and what problems it solves, I'll try to explain, however hard that may be. I might fail though. If you are interested: my last year's talk [Python, asyncio, libgpiod, and Pointless Blinking](https://media.ccc.de/v/glt24-435-python-asyncio-libgpiod-and-pointless-blinking) contains a deeper [asyncio](https://docs.python.org/3/library/asyncio.html) introduction.

Wie mit Hilfe des Open Source Werkzeugkastens (mimtproxy, curl, jq, ..) ein behördlich eingesetztes System analysiert und dabei die Sicherheitsversprechen des Herstellers in Frage gestellt wurden. Aufgrund fehlender Sicherheitsmechanismen war (ist?) es für unprivilegierten Benutzeraccounts in der „moPS App Engine“ möglich willkürliche Schreiboperationen durchzuführen. Hierdurch werden in Folge mehrere Angriffsszenarien wie Rechteausweitung, Datenabgriff, -manipulation und auch die komplette Übernahme des Systems möglich. Das System wird z.Z. von verschiedenen Bundesländern Österreichs, der ASFINAG oder auch der deutschen Bundespolizei eingesetzt.

Beyond Microservices: Running VMs, WASM, and AI Workloads on Kubernetes (glt25) 49:45

לפני 5 weeks49:45

49:45

Kubernetes has evolved far beyond its roots as an orchestration platform. Today, it's a powerful and flexible engine capable of managing a wide variety of workloads, from virtual machines to WebAssembly applications to AI inference models. In this talk, we'll explore how Kubernetes can be leveraged to run non-traditional workloads, tackling common challenges and showcasing cutting-edge solutions. We'll start by discussing KubeVirt, a technology that enables seamless migration of on-premise VMs into a Kubernetes environment, making it easier to consolidate infrastructure and modernize legacy systems. Next, we’ll dive into WebAssembly (WASM) workloads using SpinKube, highlighting WASM’s security, sandboxing, and near-instant startup times that make it ideal for lightweight cloud-native applications. Lastly, we’ll cover running AI models and inferences on Kubernetes with an emphasis on optimizing performance through proper cluster topology, hardware considerations like GPUs, and scalable configurations. Throughout the talk, I will showcase live demos of each workload type—VMs, WASM apps, and AI models—running on Kubernetes, providing practical examples and real-world use cases. Whether you're looking to expand Kubernetes usage in your projects or exploring new workloads to orchestrate, this session will offer valuable insights and hands-on solutions for diverse compute needs.

Are we digital typesetting yet? (glt25) 48:42

לפני 5 weeks48:42

Digital typesetting is the art of creating digital documents based on user-provided data. In this talk, I want to ask the question: are we digital typesetting yet? There is a myriad of requirements for a modern typesetting system: From Unicode support to i18n, i10n, and a11y. From a large corpus of markup languages to multiple image file formats. From EPUB to PDF. People do not want to miss out latest trends in typography like variable fonts and emojis. And in the end, every part could be provided by a human, a computer, or some AI. Do we have the tools at hand? Can one system even implement all those requirements? I want to evaluate how various tools like established LaTeχ, newcomer typst, and various others like speedata Publisher and SILE satisfy those requirements. What are their strengths and what are their weaknesses? Can they be adapted to missing requirements? And what about frontends like sphinx and Quarto? My goal for this talk is to give every attendee some guidance for the future which tool might suit their usecase.

DIY: Build your own mechanical Keyboard (glt25) 46:47

לפני 5 weeks46:47

46:47

The keyboard is your main interface to the computer and most of us use it for hours everyday. Therefore, it makes sense to have the keyboard customized to your liking. We will explain what mechanical keyboards are and what different levels of customization are possible and why you may want them. Additionally we present the necessary tools, skills and resources you need and show you how easy it is to either modify a commercial keyboard or create your own - completely new from scratch. # DIY: Build your own mechanical Keyboard ### Why, how, and how deep is the rabbit hole? Improving the office setup usually doesn't go much further than buying an ergonomic chair or maybe a wrist rest. However, the keyboard is your main interface to the computer and most of us use it for hours everyday without ever thinking about it. Therefore, it makes sense to improve the experience and have the keyboard customized to your liking. This can be done with mechanical keyboards, which are often seen as superior to the more common membrane keyboards. They usually offer a better typing experience with options for tactile and audible (clicky) feedback, are more durable and damaged keys can be easily replaced, while switches can even be hot-swapped. Additionally they allow all kinds of customizations up to a completely custom build. First, we will explain what mechanical keyboards are, how they work and why you may want one. To illustrate this, we will briefly tell about our journeys and different reasons why we finally ended up building our own keyboards. Next, we will talk about different levels of "building your own" keyboard. Starting from programming different layouts and exchanging switches on a commercial one, over changing the firmware up to completely building a keyboard, either from some open hardware project or from scratch, creating your own unique keyboard. We will explain in detail the different customization options, which skills and tools are necessary, which resources are available and how easy it really is to build a keyboard. Additionally, we will show demos of what can be built and what can be achieved with different levels of customization. At the end of our talk you will know about: - All required components of a keyboard - What level of customization you might want - How and where to start with your own mechanical keyboard project Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.linuxtage.at/glt25/talk/H7AVKF/…

Was ist Open Source Software (OSS)? Was unterscheidet OSS von anderer Software? Welche Lizenzen gibt es? Welche Lizenz wähle ich für mein Projekt? Was muss ich beachten wenn ich Open Source Software einsetze? Was ist Open Source Software (OSS)? Was unterscheidet OSS von anderer Software? Welche Lizenzen gibt es? Welche Lizenz wähle ich für mein Projekt? Was muss ich beachten wenn ich Open Source Software einsetze? Dieser Vortrag soll eine Grundeinführung in OSS Lizenzen geben und beleuchtet die Unterschiede der populärsten OSS Lizenzen. Die kleinen feinen Unterschiede zwischen den Lizenzen können essentiell sein um die Verwendung deiner Software einzuschränken oder großzügig frei zu geben. Du ermöglichst leichteres Teilen oder verpflichtest zur Freigabe geändertere Varianten. Manchmal möchte man großen Einzelhändler:innen das Verkaufen der eigenen Software in ihrer Cloud als Software as a Service Lösung verbieten.

Von Multi-Cluster bis Hybrid-Cloud: Flexibles Kubernetes-Scheduling mit Karmada (glt25) 53:39

לפני 5 weeks53:39

53:39

In einer zunehmend komplexen Welt von hybriden Clouds und global verteilten Anwendungen stellt die Orchestrierung und das Scheduling über mehrere Kubernetes-Cluster hinweg eine echte Herausforderung dar. In diesem Vortrag wird Karmada (Kubernetes Armada) vorgestellt, ein Framework, das die Ausführung von Cloud-nativen Anwendungen über mehrere Cluster und Clouds hinweg ermöglicht, ohne dass Anpassungen an den Anwendungen vorgenommen werden müssen. Wir demonstrieren die zahlreichen Funktionen wie Hochverfügbarkeit, Fault Tolerance und Traffic Scheduling live in einem Hybrid Cloud Setup, um die Flexibilität eindrucksvoll zu veranschaulichen. Dieser Vortrag richtet sich an fortgeschrittene SRE's, Platform Engineers und #CloudNativeNerds, um neue Horizonte zu eröffnen und in die Welt des Kubernetes Cluster Managements einzuführen.

Die Cloud-Migration ist ein entscheidender Schritt zur Modernisierung unserer Softwareanwendungen und zur Sicherung unserer Wettbewerbsfähigkeit. In diesem Vortrag werden wir unsere Reise, Herausforderungen und den strategischen Plan zur Einführung cloud-nativer Technologien teilen. Unsere Reise begann mit mehreren Proof-of-Concepts, um unsere bestehenden Softwareanwendungen in die Cloud zu migrieren. Letzten Sommer gewannen wir durch die strategische Partnerschaft mit Microsoft erheblich an Schwung. Nun benötigen wir eine umfassende Cloud-Adoptionsstrategie. Unser Ziel ist es, mehr als 50 Anwendungen als Software-as-a-Service (SaaS) für unsere Kunden anzubieten. Dies erfordert eine technische Transformation und die Entwicklung eines tragfähigen Geschäftsmodells für unsere SaaS-Produkte. Wir stehen vor mehreren Herausforderungen, da dies unser aktueller Stand ist: * Ein heterogenes Softwareportfolio * Mehrere Geschäftseinheiten und Teams * Unterschiedliche Technologie-Stacks * Mangelndes Wissen über den Betrieb cloud-nativer Anwendungen Um diese Herausforderungen zu bewältigen, konzentrieren wir uns auf: * Cloud-Native Readiness: Vorbereitung unseres Unternehmens auf cloud-native Operationen. * Infrastructure as Code (IaC): Nutzung von IaC, um Cloud-Ressourcen konsistent zu verwalten und bereitzustellen. * Automatisierung: Automatisierung der Bereitstellung unserer SaaS-Anwendungen, um Effizienz und Zuverlässigkeit zu gewährleisten. Indem wir diese Herausforderungen direkt adressieren, wollen wir unser Softwareportfolio transformieren und unseren Kunden robuste, skalierbare SaaS-Lösungen anbieten. Funktioniert dies reibungslos? Finde es raus und begleite uns auf unserer Reise! Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.linuxtage.at/glt25/talk/VGX8LW/…
