I am now retired, but have worked as a Novel & Cisco engineer, and developed various electronics. Today I play with ESPhome, Home Assistant, model train, and teach a little about 3D design in FreeCad & electronics design.
I am a big fan off Linux, and have totally opted out of windows, I like to spend time showing people that they do not need to buy a new computer and printer, just because a new version of windows is coming, I have upgraded many pensioners’ PCs to run Linux, and people are often surprised that a free program can run so stably.
