Old stuff I still knowOur Ginger Fuhrer says that he could still code up a simple game idea in Amstrad Basic, while I'm your man if you ever need to rebuild the suspension on an Austin Allegro (1750 Equipe version). This stuff doesn't leave your mind - tell us about obsolete talents you still have.

one lecturer was a valve (that's vacuum toobs for you 'merkins) guruand used "Better Be Right Or Your Grid Bias Voltage Goes West"
he was still using it when he was teaching us in the 90s.
Being a latecomer to valves (I've since built some amplifiers), I now know enough to understand his aide memoire.
a grid roughly equates to the base of a transistor, the anode the collector and the cathode the emitter. so if the grid bias is badly wrong, you could end up making the current flow from anode to cathode far exceed the design limits of the valve. in laymans tems this often means bangs, flames and smoke as various other resistors and capacitors briefly, but spectacularly, exceed their own ratings.
good times!

This one I like...Also
Change Grid to Gate and it's current again.
See what I did there ? Oh well, please yourselves...
