Thanks, @MichaelTunnell - very interesting and informative, as usual I remember the (proprietory) Motif widget set for X from back in the 90s. That was before either GNOME or KDE were around. We used Window Managers then and I seem to recall having to manually edit X configuration files for this. Was possible to fry multisync monitors quite easily in those days if you got refresh rates wrong when starting X manually! Glad Debian patched sudo promptly, as I’m sure everyone else did. Given how critical this program is, I wonder if it’s ever been independently audited? Might be useful. I’ve just started looking at GTK coding working from the C original then going upwards to C++ and other bindings. They recommend a classic (now online) text on security when coding for Linux as the types of errors that can cause security breaches often aren’t covered in programming courses. I am especially interested in UBPorts work and wonder if they’ll be affected much by Qt LTS becoming commercial only. Always good to hear of updates to stalwarts like Plasma and Firefox too!
