Hi, I am R.D. (I go by my initials.) I am the granddad of granddads at 80 years old.
I first learned FORTRAN in a Statistics Department before there was a computer science department. I taught physics for 36 years and taught BASIC in Computational Methods in Physics class. I also learned a little assembly language for the 6504 chip.
I am learning PYTHON and some LISP to keep my mind active in retirement.
I just learned about PYTHONISTA and look forwarded to using it.
