I've had the idea for a while to use an LLM to gather metadata about books for me as well as generate tag lists for themes, plot, writing style, etc for everything in my ebook library. You could also generate non spoiler plot summaries and produce recommendations for similar books.
I leverage btrfs or ZFS snapshots. I take rolling system level snapshots on a schedule (daily, weekly, monthly and separately before any package upgrades or installs) and user data snapshots every couple of hours. Then I use btrbk to sync those snapshots to an external drive at least once a week. When I have all of my networking gear and home services setup I also sync all of this to storage on my NAS. Any hosts on the network keep rolling snapshots stored on the NAS as well.
Important data also gets shoveled into a B2 bucket and/or Google drive if I need to be able to access it from a phone.
I keep snapshots small by splitting data up into well defined subvolumes, anything that can be reacquired from the cloud (downloads, package caches, steam libraries, movies, music, etc) isn't included in the backup strategy. If I download something and it's hard to find or important I move it out of downloads and into a location that is covered by my backups.
SpaceX has a very robust management system that manages musk and keeps him out of the day to day. That's the most impressive thing about them IMO. Tesla used to be better about this as well, but with the whole eDumpster (aka cybertruck) fiasco that system seems to have largely fallen apart.
Blue state blue country and we were expected to recite the pledge every morning of k-8 (I don't recall it being a thing in high school.) I remember kids whose parents were politically active being punted out of class for not participating. About half of us would just follow along with "blah blah blah blah blah blah blah" at the cadence of the pledge.
