Ron's Brain Dump

This page is read only. You can view the source, but not change it. Ask your administrator if you think this is wrong.
This is an outline generated by Copilot; as an outline it seems quite thorough; obviously there are lots of bits to add but basically i was interested in the History of Software Engineering from the first SDE (Ada Lovelace) to today (which seems almost entirely AI-centric).

Great — outline it is. No fluff, no filler, no yackity‑yack. Just a clean, structured, high‑signal document you can scan fast and use as a reference.
