I started using emacs in the early 1980s. Just found out I could use it on my cell phone. Never thought I would be using it on a phone I can carry around. I just have to carry a magnifying glass to see the text with my aging eyes...
I just spent the better part of the summer coming up with KICAD schematics for an apple II clone that I have had for 40 years. Surprised that I could fit it all on one large sheet.
They deleted my youtube vids. Now there is guy in California that claims he invented what was shown as an invention in one of my videos. Got $10 million in startup capital for it. Video was 2009.
