Electrons are spin of 1/2, so electronics must also or else the electrons misbehave.

Sounds like the're working for way below minimum wage. It's not worth your time if it takes more then 3 minutes to save 50 cents.

Nah, those are all drones that resemble dinosaurs.

I would think the metal parts of roof might be reflecting signals all around the building, which would cause interference between devices. (there is a limited number of WiFi channels), it might work better with a plastic roof, or one with RF absorbers.

Well, it lasted longer then any of my drones do before I have to replace a propellor. (That might be a bit harder on Mars)

Just disconnect all the radios/antennas, including trace antennas as PCBs. The car can collect all it wants as long as that stays on the car.

Also make sure to get hidden transmitters, like TPMS sensors (they have been used to track people before).

You can't really do anything about ALPR without committing crimes in most countries.

I have done some tests, and under low memory conditions, when frequently writing to the drive (especially with a high /proc/sys/vm/dirty_writeback_centisecs) swap can actually reduce the amount of writes to the drive. If you do have enough memory, swap is hardly used but still results in a noticeable speed improvement.

These are literally the worst investment possible, because all the value comes from speculation (people buying them to get rich quick). As soon as those buyers get spooked the cones crashing down to zero. With something like a share in a company, that entitled the holder to partial ownership of the company. Even if the company goes bankrupt, you would still get a share in the former assets of the company. You can of course lose money if you buy at a price that is much higher then the actual value due to speculation, but this is limited by the intrinsic value of the company's assets.

Too many users, the Lemmy instance software is not very fast.

Here is a (few weeks old) chart of users by instance:

Ext4 is old, but fast and very robust. You won't loose data or corrupt the filesystem if your system looses power. It can even survive partial wipes, if you accidentally overwrite the first few megs of you drive with a messed up dd, nearly all your data will be recoverable, including filenames and directory structure.

It doesn't have very fancy features, but it is the best tested and most robust option available. (also the fastest due to its simplicity)

Btrfs has things like copy on write files that can protect you from an accidental rm, but this won't save you from drive failures, so you still need backups for important data.

Just move to another instance, and leave the lag behind.

No, not lemmy.ml or sh.itjust.works or beehaw.org, find a small one, the experience will be better. (Try a themed instance so your local feed us useful)

The single biggest improvement from here is to increase the contrast so the text is readable. https://contrastrebellion.com/
