Methodolgies
Programming methodologies have changed over the years. When I started programming in the 1970s it was enough that the program ran. In those days we were very limited in what we could do. I was programming on a machine that had 4 kilobytes of RAM. Compare that with the pc that I am using today which has 8 gigibytes of RAM. The 1970s computer was a 8 bit machine, this is a 64 bit machine.
