Yesterday, I dug up some old computational #physics code and something wonderful happend: it worked! Out of the box. Wicked!

I'd written some #matlab code back in ~2002 to solve the diffusion equation. Since I don't have Matlab anymore, I installed #octave and tried to run the code. Give it a go, see what happens. YOLO, and all that. And it ran without change! 😱 Even the plotting worked. I take my hat off to the Octave devs for ensuring such amazing compatibility. Thank you 😃
