I started programming in Basic language when I was 14 years old. The second programming language I learned was Z80 assembler. I've been programming with C++ for the last 20 years. I attended the 2012 C++ Now event in Aspen and it was the most exciting experience I've lived in my professional life. I met a lot of brilliant C++ minds and I have very good memories from that trip.
