Benjamin Turnbull will tell us about Qubes OS, a "reasonably secure operating system".

Tim Laurence automated the watering system for his garden using a Raspberry Pi. He will tell us how he did it. This will be a beginner-friendly presentation. 

James Kelsh will show us how to install and run Linux in a virtual machine, using Windows 10 as the base operating system. This topic is intended to be accessible to beginning Linux users.
 

In celebration of the Debian Project's 25th anniversary, Hubert Chathi will talk about his experiences as a Debian Developer, including technical components (such as building Debian packages) as well as non-technical aspects (such as Debian's history).

Colin Knapp will update us on GitLab, the "open core" Git-repository manager. He calls his presentation "Creating Problems to Solve Problems in GitLab". Some of the topics he will cover include:

• How to organize and compartmentalize projects to reduce testing and growing pains.
• How to deal with increased complexity in compartmentalized projects
• The GitLab development cycle tools he uses when working on Tugthr.
• How he uses the built-in Kanban boards and commit messages to close tickets
• How GitLab-Runners work, and the difference between shared cloud runners and runners on your own hardware.

Khalid Baheyeldin has been playing with inexpensive Wifi and Bluetooth enabled microcontrollers. These can be programmed using the Arduino IDE or Micropython (which runs on the chip instead of an operating system). He will tell us what he has been using these for and how he has set them up.

Mark Steffen will demonstrate how to detect compromised sites using tools such as Burp Suite, Nikto and Vega.
