+  * 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.\\ {{https://wiki.dfupdate.se/_media/projekt:2024-11-02_drawing_with_sound.pdf|Slides}}
+  * 2024-04-20, 19:00: **Lightning talks**\\ In five-minute talks Update members present their projects and interests.\\ //Andreas Lindmark//: Descriptive Geometry\\ //Fredrik Wahlqvist//: Beekeeping\\ //Sanna Kurdahl//: Why you should go to the library\\ //Bjarni Juliusson//: The programming language Joy\\ //Johannes Holmberg//: Prince of Persia with hardware sprites
+  * 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 Some of the data might be useful, some of it entertaining, some considered useless and some outdated.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.
+  * 2023-09-09, 19:00: **Passwords, please.**\\ //Francisco Blas Izquierdo Riera
+ (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.\\ {{2023-09-09_passwords_please.odp|Slides}}
+  * 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.
+  * 2023-05-13, 19:00: **The inspirator – Your personal table-top Brian Eno**\\ //Bjarni Juliusson (Update)//\\ A programmer carrying a screwdriver demonstrates the use of microcontrollers and various e-waste in a random-advice-printing machine he built for his artistic mother.
+  * 2023-02-11, 19:00: **Design for 3D printing – CAD programs and design tips for successful printing**\\ //Rikard Lindström (Update)//\\ 3D printers are cool, but despite what it might look like on social media, they can print other things than small plastic boats. When you learn to realise your own designs it's almost like a super power. Follow along and learn a bit about 3D printers, what (free) software there is for designing 3D models, and how to design for reliable and easy printing. The presenter will bring some 3D printed items that you can get a closer look at if you join the lecture on site at Update's premises.
+  * 2022-11-12, 19:00: **The Hitch-Hiker's Guide to Artificial Intelligence – BBC Basic Version**\\ //Herbert Lange (IDS Mannheim)//\\ Imagine it's the eighties and you are interested in this hype called Artificial Intelligence. You might have heard of LISP and PROLOG but all you have is a home computer running Basic. Would it be possible to do fun experiments without having access to all the compute power universities have access to? The authors Forsynth and Naylor answer this question in their book "The Hitch-Hiker's Guide to Artificial Intelligence" and provide an overview of interesting topics combined with example programs written in BBC Basic which you can type in yourself and try on your UK-built home computer. In this talk I will go through some of these examples and try to put them into a modern context.
+  * 2022-10-09, 14:00: **Who am I? CPUID on the PDP-8**\\ //Pontus Pihlgren (Update)//\\ Portable software must adapt to peculiarities of the target platforms. Even variations within a "compatible" family of computers may require specific code. But how does a program identify which machine is executing it? In this presentation we will dissect, line by line, a subroutine written by the late Charles Lasner (CJL) as part of the Kermit implementation for the PDP-8 family of computers. The subroutine, "MACHINE", is capable of identifying all DEC PDP-8 models. Some familiarity with programming will benefit the listener, but the presentation includes the basics of PDP-8 assembly and the level should be approachable to most.\\ Please note that this talk is given as a part of the [[https://vcfb.de/2022/index.html.en |Vintage Computing Festival Berlin 2022]] this coming weekend, **the time and place for watching the lecture stream are different than usual**.\\ Stream: https://streaming.media.ccc.de/vcfb2022/Signallabor\\ Q&A: https://bbb.cryptoparty.se/b/upd-0mo-m2u-aq8
+  * 2022-09-10, 19:00: **How (not) to do public open WiFi**\\ //Jan-Daniel Kaplanski (German Red Cross)//\\ With increased refugee numbers, an unprecedented high demand for the possibility of communication with the remaining family members left home arose, rendering the previous solution insufficient. That previous solution was based on one WiFi AP and one repeater each per building, connected to a 50 Mbit/s DL/UL synchronous optical fibre network via an external VPN provider to ensure network separation with the company’s staff network. The aim of this project was to provide a new fast solution with its separate external connection, by building a separate network from the ground up. This is an ongoing endeavour, which has currently reached its test phase with three operational APs across two buildings and eight network switches across six buildings, more to follow.
