DG114: Irgendwas mit Unterschriften - eventuell mit Stempeln (datengarten)
Jun 4, 202500:33:39Tap to summarizeAm 04. Juni wird es wieder einen Datengarten geben, der von tomate gehalten wird. Es wird unter anderem um die Themen Unterschriften, Signaturen und Stempel gehen. tomate hat sich viel zu lange mit Unterschriften und Stempeln beschäftigt - und ihr werdet das dann auch. “Dieses weiße Blatt Papier ist nix wert. Wenn ich das bedrucke, ist es immer noch nichts wert. Wenn ich aber unten eine Unterschrift darunter setze, entfaltet sich Magie.” Wir werden dieser Magie auf den Grund gehen und eine Reise durch die Welt der Unterschriften und Stempel unternehmen. Kommt vorbei oder schaltet euer Gerät ein und verfolgt den Stream. Dieser Beritrag wurde elektronisch erstellt und ist ohne Unterschrift gültig.

Ink/Stitch (lgm2025)
May 31, 202500:28:39Tap to summarizeMachine 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/

How to Run a Film Festival on Libre Graphics (lgm2025)
May 31, 202500:22:24Tap to summarizeOrganising a film festival is 90% communication. The FOSS and Libre Graphics toolbox is well-equipped for this. However, for many of the tasks that a festival entails (video formats, subtitles), we needed to dig a little deeper. Hear about the challenges we faced and the solutions we came up with! ## Links * [website: LusOFest](https://www.lusofest.de) Licensed to the public under https://creativecommons.org/licenses/by/4.0/ about this event: https://pretalx.c3voc.de/lgm25-upstream-2025/talk/2743934851/

Printing Maps with Spot Colors (lgm2025)
May 31, 202500:31:20Tap to summarize… 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.

TypeRoof —Type Tooling Infrastructure (lgm2025)
May 31, 202500:22:02Tap to summarizeTypeRoof 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/

Inkscape UI Vision Going Forward (lgm2025)
May 31, 202500:21:02Tap to summarizeThis presentation explores UI improvements for Inkscape, aiming to make it more welcoming for newcomers while enhancing efficiency for experienced users. It showcases design concepts, feedback from the UX team, and discusses how UI refinements can strengthen Inkscape's community. ## Links * [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/2407556856/

Libre Designers and the Software Apocalypse (lgm2025)
May 30, 202500:29:10Tap to summarizeSo, 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)
May 30, 202500:20:07Tap to summarizeIn 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!

3000 % FasterFile Saving With Time Travel (lgm2025)
May 30, 202500:20:39Tap to summarizeA 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/
