-  * 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}}
+  * 2026-04-11, 19:00: **Idris – Reviving an Early Unix Clone**\\ //Michael Engel (University of Bamberg)//\\ The ideas behind Unix have significant impact on the design of a large number of operating systems. In addition to more recent systems modelled after Unix, such as Minix or Linux, early operating systems inspired by Unix, such as Coherent, Venix, and also the [[https://en.wikipedia.org/wiki/Idris_(operating_system)|Idris OS]] developed by the company Whitesmiths, existed already in the 1970s. For many years, almost the only information available about Idris was a short Wikipedia page. This has changed in 2025 when a PD68 computer, an Idris-based Motorola 68000 system developed as a project of computer hobbyists in Sweden and Norway, [[https://forum.vcfed.org/index.php?threads/pd68-68000-based-vme-system-running-idris.1252893/|was donated to the computer museum in Dalby]]. Subsequently, an international cooperation also managed to get hold of and run the [[https://github.com/9nut/IDRIS-OS-for-Atari-ST|Atari ST port of Idris]], which extends the regular Idris system by providing a version of the X10 window system. In this talk, we give details about the recovery of Idris using emulation on different abstraction layers. In addition, we give an introduction to the structure of Idris for Motorola 68k-based systems with a focus on enabling Unix to run on computers lacking virtual memory management.
