Software-Development

“Dad, what is this?” I said, opening PB.EXE on my 386 machine.
“You can program the computer with this, it’s called PowerBASIC.”, he said.
Armed with two reference manuals I went with it.

My first useful program came to life three years later, a GUI re-implementation of his DOS utility “Growth Curve Analysis” performing linear regression for parameters of a specific function describing the growth of birds using Delphi.

Two years later I “invented” what the world commonly calls interpreter, a crude C++ program that parsed a string into an evaluable function. I creatively dubbed my invention “Mathstring”. Studying mathematics didn’t come easy and it took some time until courses required more programming again.

I focused on numerical analysis and, supported by my first programming job, I dove deep into C++ and even implemented symbolic differentiation via template meta programming. Eventually I discovered C++ FQA Lite in 2010 and soon contracted the LISP bug (thanks Yossi!).

I finished my studies and got a great job writing Java and PHP webapps.

Clojure entered the picture in 2016.
