Old school coder. The first program I made was on an old - really old - machine that was originally used to compute ballistics for artillery before WWII. You programmed the calculation by physically building the logic with patch cords on a plug board. That was just nerd recreation in high school.

Since, mostly C, C++, perl, python, SQL, R and whatnot.

I bike for recreation, like dogs, not cats, learning TensorFlow, and generally just take care of stuff.
