Years ago I was watching Doomsday Preppers and one fella dug a long trench, 100 foot if I’m not mistaken.

In the trench he laid a large PVC pipe and filled in the trench. At the far end of the pipe there was an air inlet. He ran the pipe into his basement and up inside a wall with an inline fan. Cool air, as well as fresh air.

Didn’t do anything for the humidity, I suspect.

He claimed it worked, I can not confirm.

It does make since as it’s about 4c/39f four feet/1.2m underground.

Agreed. The Mythbusters concluded that it’s the amount of food eaten that makes a person sleepy.

I prefer not use use a sync “solution” that has been in beta for 3 years.

When I was using Android tablet and phone, Quillpad is what I used. Very similar layout to Keep. It doesn’t have sync built-in but does have markdown. I used to export a note and sync with Syncthing.

When I switch my tablet for a Linux laptop I had to find something else. Notesnook is what I went with. The layout is more of a list of notes v Keep’s twin columns, has sync in the free version (works great) and markdown.

Markdown is optional with both apps.

Check the minimum operating temperature. Most ACs will start throwing hot air if the outside temp drops to 18c/64F. Not a problem if it’s going to stay warm overnight but towards the end of summer the night temps can dip fairly low.

Linux, torrents, youtube (if you use a account-less frontend), Wikipedia.

They are free where I live.

Not much. My main interest is digital privacy. Perhaps 10 years of service with Proton.
