A lot of things and it was changing constantly. But as soon as I discovered computers, I was trying to find a way to learn how they work.
My first “programming” memories are copying BASIC programs from a book into the ZX Spectrum, making a TV screen change colors and print text. I was hooked.
Knowledge sharing and networking. Some of the best conversations I had were in between conference sessions with people that I didn’t know before.
I’m always reminded of the saying that I heard from older electrical engineers: “There are no ghosts in technology”, but sometimes while chasing a strange bug you start to doubt.
