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

The code prints progress information so that the user knows something is happening while the calculation is running. At least, that was necessary back in the early 2000's, on a specialised "workstation". But, on my laptop yesterday, the progress text whizzed past so fast, I couldn't read it. It's no longer necessary. I know it's obvious, but computers are *so* much faster now. 🤯
