Printing Maps with Spot Colors (lgm2025)

… 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...

3000 % FasterFile Saving With Time Travel (lgm2025)

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)

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...

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

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...

From Printer Dust Till Graphics Dawn (lgm2025)

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...

Libre Designers and the Software Apocalypse (lgm2025)

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...

Рецепт фасолей: как я отреверсил бюджетный кнопочный телефон, хакнул его и научил запускать нативные программы на C

Осторожно: помните ли вы, как в вашем телефоне Siemens, Motorola и Sony поселились маленькие программы — «эльфы»? В рамках этой статьи мы во всех деталях исследуем прошивку бюджетного кнопочника, разберемся в её архитектуре, хакнем и напишем загрузчик тех самых эльфов с MicroSD-флэшки. При этом я постараюсь объяснить всё максимально простым и доступным языком!

Недавно я познакомился с легендой форума allsiemens.ru — Ilya_ZX, который известен своим огромным вкладом в тему реверса и моддинга телефонов на платформе E-Gold и S-Gold. Илья поведал мне интересную историю о том, как в начале нулевых, будучи студентом, поспорил с одногруппником, сможет ли он добавить ‭‭«змейку‭‭» в свой...

How Big Tech Exploits Apps to Circumvent Privacy Laws & a Solution from Purism

Despite the promises of robust privacy laws like Europe’s GDPR and California’s CCPA/CPRA, Big Tech continues to push the envelope when it comes to data collection. This is especially the case with regard to mobile applications.

Elektronisches Patientendossier! Aber wie genau? (dgna)

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 Mitgründer und gemeinsam sind sie CEO von movos, einem Anbieter einer Lösung zum Halten und Teilen von Gesundheitsdaten. Sie zeigen uns auf, wie movos den Spagat zwischen dem Schutz der Privatsphäre von Patientinnen und Patienten und dem Teilen sensibler Daten mit dem Gesundheitspersonal...
