+  * 2025-10-18, 19:00: **Meshtastic**\\ //Herbert Lange (University of Gothenburg)//\\ [[https://meshtastic.org/|Meshtastic]] is a license-free¹, open-source², encrypted³, off-grid⁴, radio mesh network⁵ on top of LoRa⁶. It is popular because it is very open and the hardware is cheap. It can be both used to communicate from person to person or in automatic applications, such as sensor networks. In this talk I will give some technical background and explain all the necessary concepts (¹-⁶). I will also tell you about my own experience with the technology so far and how you can get started yourself.\\ {{2025-10-18_meshtastic.pdf|Slides}}
- (Chalmers)//\\ This year marks the sixtieth year since passwords were first documented as being used with computers. Nowadays, entering your username and password is still one of the most common approaches to access services. And yet, despite this long time, we still cannot seem to get them quite right. In this talk we will start with a survey of the history of password security from the first time shared systems, to the modern ways to protect them. We will then discuss what makes a good password and provide tips on how to generate them. Finally we will introduce some of the latest developments in the field of password security.

+  * 2025-01-11, 19:00: **Lightning talks + 38C3 talk watching**\\ We start the evening with lightning talks, five-minute pitches of a project, tool, or some other interesting thought you want to share.\\ //Anke Stüber//: The presentation viewer pdfpc\\ //Andreas Lindmark//: The Office Method\\ //Felix Klee//: DocURLs  [[https://files.f76.eu/dfupdate/2025-01-11_docurls|More information]]\\ //Pontus Pihlgren//: TBA\\ Afterwards we pick a [[https://media.ccc.de/c/38c3|recording from 38C3]] to watch.
+  * 2024-11-02, 19:00: **Drawing with sound – From drawing mushrooms on an oscilloscope towards driving a plotter**\\ //Herbert Lange (University of Gothenburg)//\\ For quite some time, sound has been used to draw animations on oscilloscopes. That has even led to the creation of oscilloscope music, sounds created to both generate appealing visualisations while at the same time being musically pleasing. The basic idea is that sound can be represented using voltages which can be visualised on measuring equipment such as oscilloscopes. In my own project I want to explore if similar techniques can be used to drive a voltage-controlled plotter using a small TURTLE-like language.\\ {{2024-11-02_drawing_with_sound.pdf|Slides}}

+  * 2024-03-23, 19:00: **Forth — your favourite programming language that you don't know yet**\\ //Bjarni Juliusson//\\ The talk introduces Forth, a curious programming language that quite possibly doesn't look like any other language you have seen. Despite never quite making it into the mainstream in its 54-year life so far, it has made it into space on several occasions, including on the ESA asteroid-lander Philae, the NASA Saturn probe Cassini, and the Swedish satellite Freja. Both a language and an interactive development environment, Forth takes a minimalist approach to syntax (there isn't any) and provides maximum flexibility for you to develop your own application-specific languages very close to the hardware. It's hard not to like it!\\ [[.:updateringar:2024-03-23-forth-bjarni|Code]].
+  * 2023-11-18, 19:00: **Data management and digital preservation of (research) data**\\ //Herbert Lange (University of Gothenburg)//\\ We are surrounded by large amounts of data wherever we look. Some of the data might be useful, some of it entertaining, some considered useless and some outdated. Usually research data falls in the first category, sometimes even in the second. We are usually interested in managing and preserving data that seems relevant to us. Because research data is usually considered very important there have been major efforts in managing and preserving it. However, aspects of digital preservation for research data are also relevant e.g. for retrocomputing. Sometimes the two even overlap such as in the [[https://diskmags.de/|diskmags project]]. This talk will present work on data management and digital preservation mostly from a research point of view but will also highlight similarities to issues within the retrocomputing scene.

   * 2023-06-10, 19:00: **Hackerspace Design Patterns – What can Update learn from them?**\\ //Anke Stüber (Update)//\\ The Hackerspace Design Patterns address common problems and solutions for hackerspaces, like how to make decisions, how to keep the space clean, or how to involve new members. They are based on years of experiences from several communities. When the first version of these patterns was presented in 2007, it initiated the founding of hundreds of hackerspaces all over the world. Since then, the patterns have been developed further to incorporate lessons learned from a diverse range of hackerspaces. In this workshop I want to present some of the design patterns and discuss how they relate to Update.
