That's the thing with Linux in my experience...it works great...until it doesn't.
Have you tried re-applying that update that screwed everything in the first place?

I agree. I do understand that it is kind of a hobbyist's OS.
But Ubuntu should be a step better than this really.
I saw 3 other kernel versions in GRUB and tried each one of those but none of them would work either.
I really had no idea what I was doing so I could've done something wrong but I just couldn't get it back.

I would not call it a hobbyist's OS...
It is extremely good at development - I do it on a very serious level all the time...
The 'problem' is that it is way to versatile and de-centralized for it's own good...
So it is very easy to miss settings and get it wrong...
In other word it is definitely not 'out-of-the-box' OS... not even Ubuntu...

I agree with you. I think it is far better than the Windows side (and I've been a Windows user since Win3.0). it may have sounded like a hobbyist's OS may have sounded like a derogatory term but it wasn't meant that way. I meant that the user has to expect to work on configuration more than other OSes --- but maybe with the recent Windows updates reverting settings etc. it probably isn't any more of a consumer product.

Here's a snapshot of the GRUB kernel choices[^] I had.
I tried each one of them but none of them got me back to a good state.
Even when I tried each one I still had one screen at 1024x768.
I was very confused.

You haven't set up deja-dup to back up your stuff every day in the small hours? I have it running everywhere, some backing up locally to an SD card ("zero slot" option), others to my home server (over ssh, ED25519 keys - no password logon allowed!).
I also have various cron jobs running rsync to replicate stuff in an accessible form around the room.

If you have anything within a light-year of the the default GRUB setup, your previous kernel will still be available on the boot menu (which you may have to poke something to see).
Cheers,
Peter

Check out this snapshot of my GRUB choices -- I took a picture of the screen[^].
It shows that I had at least 3 options of older kernel versions & I had hoped that running one of those would fix my problem, but none of them did. Each time I would only get one screen at the 1024x768 size.
I couldn't get around it at all and that's why I finally bit the bullet & did a complete reinstall.
Now I'm afraid the kernel update is going to get pushed on me again and I'm wondering what I should do.
Any suggestions you have I will take.

I've never needed to back out a Ubuntu update, so I'm not sure of the exact procedure.
It probably depends on how you get the updates pushed to you. (I use Canonical's Livepatch.)
The magic word for searching is "blacklist", so something like "blacklist ubuntu module" or "blacklist ubuntu update" should drag the usual suspects out of the ether.
I know you can block things as late as actually loading the kernel, but that potentially leaves a hole in functionality. I've seen that most often used on 3rd party video drivers (why are we not surprised?)
Sorry I can't give you a slick answer.
Cheers,
Peter

Maybe try some Cipolla rosa di Tropea Italy's red queen: the Tropea onions of Calabria - Great Italian Chefs These were mentioned on an episode of Stanley Tucci: Searching for Italy a couple of episodes ago. Though you might have to travel to Tropea to find them. Sigh. The things we have to do for research.

Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I figured out a simple way to (I think?) expand the number of nodes on an ESP-NOW mesh network past the supposed maximum of 20 by simply not keeping peers around. Instead, I add a peer, send a message, remove the peer. You can still receive messages from peers when they aren't added, and even if you couldn't you get acks and you could delete the peer on the ack and just poll using a request/response cycle like HTTP.
It's too simple of a hack for too much of a win. Simple enough that it makes me wonder why they designed it the way they did (to keep a peer list) instead of just doing it like the above and essentially keeping no list, with everything stateless. You don't need the peer list, you just need a list of mac addresses and you can keep that in a std::map or even a std::vector if you need it (you can avoid that even because the nodes can broadcast their macs and you can pick them out of the air)
I don't know if I'm looking a gift horse in the mouth, or if I have the appropriate amount of skepticism about my approach.
I wonder if it's a general issue when I code. Maybe I should just take my wins as I find them.

Hmm. Issues with race conditions, perhaps? Note that the list of active MAC addresses is a state.

Indeed the list of mac addresses is, but you don't really need that as you can snatch macs out of the air, at the expense of some time and battery. It's more just an optimization.

You should not be that paranoid - trust yourself...
If it works for you - under fair test load of course - then do not disturb yourself why other done it differently...
Possible reasons to choose to manage a peer-list is performance around the management or maybe a race-condition over resources (the time it takes to acquire/release them)

Only a few more hours until my 20 year old cousin is cremated.
My uncle asked me specifically to talk at the cremation as I knew him best (I shared an office with him and my uncle).
People fear speaking in public more than they fear death, so why not combine the two? 
I'd speak in public every day for the rest of my life if I could have my cousin back though.
