In other news, a few months ago my microwave oven keypad broke; the
first two rows of numbers quit working, 012 and 345. That made things
tricky. Had to cook things for 6:66 minutes and seconds. Setting time
was hard. I assumed that some trace had broken in the membrane thing.

So last night we had a brief power failure, and now it all works! I
don't understand how that's possible.

Are you joking? A friend had an older console TV with a digital readout of the channel. Did I mention it had a picture tube? So the digital channel indicator was separate from the screen. One time it stopped working right.. I think it was not displaying numbers at all or something similarly goofy. He thought it was time to tear it apart. I told him to unplug it for a few seconds and then it worked. The tiny MCU needed a good reset. The MCU probably is never turned off since it is likely involved in the remote control circuit too.

It may have been a short power glitch that knocked it silly in the first place. His and yours.

One of the rear passenger doors on my car stopped locking about a year
ago and the key fob remote stopped working. No biggie, only an old car
anyway in which I might do 1500 miles per year tops.

Last week the door lock started working again, still no key fob remote,
but now all the warning messages on the dashboard display are in German.
It's a French car too - must be something to do with Brexit but I
haven't figured out what.

No, that would be rude.

Mine has EASY COOK, which is +30 seconds, which works depending on
what state it is in. It's complex.

It's not the code that "broke". The MCU got lost by a hardware glitch. The power supplies they use are not the best in the world and let various noise past.

Hey boomers! While you're ranting about what the lousy kids are up to
these days, there was a generation or two between the lousy boomers and

Reports say their code was littered with thousands of static/global
variables, creating almost an infinitely complex (but certainly
un-analysable) state space.

The first thing I do before starting to look for bugs in a client's
embedded device is make a comprehensive review of all global data. It's
amazing how many potential bugs you can find just by looking at the
linker map of global data.
