I live in SE NC. Duke energy has incentives for solar and they are about to pay for the installation of my Tesla charger in my garage.... It's not all bad I guess..
Shortbus
I have an alias in bashrc called upgrade. It runs reflector looking for the fastest of the newest 10 near me. Then it upgrades the keyring, then yay -syu and then paccache -r.
I have the journal limited to 100mb so I don't ever bother cleaning house on that.
I probably don't review pacman logs as often as I should, but stuff rarely breaks and is normally pretty easy for me to figure out what when it does.
Since the pump doesn't seem to mention it does the pump packaging/paperwork mention how many amps it draws?
Edit I found it. Load current < 350mA
I would think damn near any 12v DC "wall wart" would do it, but the adapter you have may not be the right size for what you have laying around.
Could grab something like THIS that comes with its own adapter.
That's a hard question.... 300blk is better than 5.56 (considering barrel length) IMO for the likely ranges id engage human targets in(likely close range, and hope to never find out). 8.6blk is my dear hunting round hands down. Where I'm at deer are 50-150 yards. 8.6blk is quiet and hits hard.
So 300blk for self defense.. 8.6blk for hunting.
Knowing what AUR pkg would help, but here is where I would look.
Systemctrl disable tab tab to get a list of what is enabled to start at boot for services and such. Disable what you don't want.
I use gnome, so I'd check ~/.config/autostart if it's an application that's starting when I login.
