Garage sensor. Uses distance sensors to detect door open/closed and car present /absent. Has buttons to open/close the doors, a 3v garage door remote. Also has a motion sensor, temp/humidity sensor and a photo resistor to understand outside ambient brightness.

Looking at building some fridge/freezer temperature and water leak sensors.

You want a "read it later" service, like Omnivore or Wallabag.

If you can pick it up in person in Markham, it's even cheaper. Bought a bunch of UPSes across a couple dozen years now, and replaced the batteries on many of them. Best prices I've found.

You are describing IPFS. If you install IPFS, then browse to some IPFS content (like a wikipedia mirror: ipns://en.wikipedia-on-ipfs.org/wiki/), that's cached on your system, if someone else requests those assets, your computer will help distribute it. You can "pin" content, keeping/seeding a copy.

I use restic extensively, and it works really really well... until it breaks. Then there's next-to-nothing you can do to fix the repo.

Rustic, on the other hand, has lock-less design, and repair options, so I end up using it to fix things. However, it has a number of rough edges: it uses its own wacky config file, its include/exclude options are wildly different and a bit painful, and to use a bunch of repo backends (like S3), you need to install, configure, and use rclone, which is poorly documented by rustic.

Not a bug. Also not a feature. Somewhere in between.
It's just a number in a database. If you are the server admin, there's no reason why you couldn't fiddle with it. When anyone asks for the profile, server sends what's in the database. They're doing the same thing with the Joined Date.

If it wasn't a bot specifically mirroring another platform's stuff, that kind of manipulative behavior might rub other server admins the wrong way.

Agree on the creepy side, though there's other possibilities besides facial recognition, namely:

• They buy data from a data broker. Said data broker bought (or got) location data from any number of apps you have installed on your phone that monitor your location data.
• They associated your phone's Wifi MAC (even if you don't connect to their Wifi) or a bluetooth MAC (of bluetooth headphones, watch, or other device) to you previously, then saw it again

Solid File Explorer, bought it forever ago, and it hasn't let me down yet.
