My learned profession is farmer and winemaker, today i try to make the farm in 10 % of my time. I started with computer in 1982, i am completly self-taught.
Iin 1985 i programmed one of the first notebook applications for nutrification of pigs for a corporation with linear optimization. Since then i created many programs for winemakers, butchers, foresters and meat wholesalers. Currently my 16 year old son is outperforming me enormously, he learned c++ in an unbelievable short time - six weeks after his first contact with c++ he was able to replace math.h with his own version! Today he creates his first multithreading program, because his new self built computer with AMD Ryzen Threadripper 1950X with 32 threads makes a big difference: 1:32 in speed.
