I bumped into Linux in 1994, whilst running a school project to monitor radio waves from Jupiter's Moon Io, which morphed into a larger solar flare radio interferometry project, using AIPS/AIPS++.
Since then, I've been involved in a couple of other activities that have involved a fair amount of coding:
Project Galileo (a remote-controlled telescope for schols), my own web development company (UKBizOnline Ltd), and more latterly, a new business in the IOT space.
Linux user since 1994. Self-taught in PHP, shell scripting, and some Python development.
