Though the way it specifies raw UTC times is odd (8601 uses Z, 3339 uses -00:00), that got changed with RFC 9557 to align with 8601.

It also supports "zoned date times", where instead of just using the UTC offset, you can also include a timezone identifier, e.g. 2020-01-01T00:00+01:00[Europe/Paris]. Useful if you're doing calculations on dates but can be ignored otherwise.

you could probably rig up a steampunk sun-following mirror positioning system by just using a shitload of math and astronomical data to pre-program a daily turning system for each individual mirror

I've got great news.

I think air scrubbers are for more intensive situations, like cleaning a flood damaged home, or painting things, since they've got chemical filters and UV sterilizers in them. Air washers are mostly just air filters that rely on water to trap stuff first and foremost, one I saw was just a series of spinning disk's half submerged in water. Surface tension caused water to stick to the disks, and a fan blew air between them, so anything in the air would get caught and pulled down into the water tray.

The other function they serve is passive humidifiers, as air passes over the water it evaporates, but only if the air is capable of holding the water. If it's already humid no evaporation occurs, so you don't get things like condensation that you'll see with active humidifiers that aerosolise water.

You can diy one by hanging up a towel, having the bottom touching a container of water, and pointing a fan at it, and capillary action will draw the water up into the towel. So with one of these boxes with cotton filters, would serve the same purpose.

I've been wondering if you could make a hybrid of this and an air washer, replacing the filters with a frame and cotton sheets and then putting it in a shallow tub of water.

I know some air filters are made of cotton to begin with, if they're already in a plastic frame you could use that as-is.

That folder (or rather whatever serves its purpose) has been around since the beginning, so all the 16-bit applications at the time would look for OS libraries in C:\WINDOWS\SYSTEM\.

Then 32-bit comes along, and you can't exactly drop 2 files with the same name in the same folder, so the 32-bit ones got put in their own named folder.

Then 64-bit comes along, and it turns out way too many applications hardcoded the System32 path to change it, so they kept the name the same and inserted a filesystem redirection for legacy 32-bit apps so when they try to read from System32 the kernel redirects that to SysWoW64.

I think that's the one thing they got right unfortunately, in real life armies (usually) don't risk soldiers trying to locate and kill a sniper, they just use things like artillery, missiles, or tanks.

Does systemd print much once it's fully running? Checking my log the only chatty thing is networkmanager doing wifi scanning, 4 separate state change log messages per scan.
