Age 77.. started with Fortran in '68 on an IBM1130, assembler on a Linc-8 in '70, then at UofWaterloo on IBM360/75 with (omg) 3MB ram. Then scientific programming mostly Fortran or asm, switched to turbo Pascal in 88-89, then Delphi and MATLAB. Currently mainly work in VsCode using markdown codeblocks in a way a bit like Jupyter (see VsCode extension Hover-Exec) for a range of stuff including art installations.
