oh. i heard that dogs only eat poo poo when it smells to them like it might have some food value, which happens when it's got undigested protein in it. you can stop your dog from eating its own poops by adding pineapple to their diet, because it contains an enzyme that denatures protein. can't stop it from eating other dog poop though

my next door neighbor in undergrad went out one nigh and poured bacon grease all over a semester's worth of shits the neighbor's unleashed dog laid... next day the dog just runs around eating like, 40 shits. the owner is yelling, trying to chase it, but he's really fat because he doesn't walk his dog he just lets it run around the neighborhood making GBS threads anyways this dog ate a shitload of poo poo and i am not sure how i feel about that like could the dog get sick? it was still alive at the end of the next semester so i assume it didn't hurt it but jeez

nah, dogs can eat basically anything no matter how rotten or gross and be fine.

like yeah sometimes the way this works is the dog eats a rotting seagull at the beach and then twenty minutes later horks it all back up all over the back of the minivan, and then excitedly eats it again and then barfs it onto the rug when you get home, but that's the beauty of nature

the number of technical challenges that hyperloop faces is astonishing and the fanboys online treat them like minor details. compared to the grand idea of "go faster because there is less air resistance".

hell the entire idea is a crazy violation of the KISS principle: pull enough vacuum to reduce air resistance but leave enough air in the tube to allow for the passenger pod to use a combination of rams and pumps to concentrate and redirect the air to the outer skin of the pod to form a bastardized hybrid hydrodynamic/hydrostatic bearing, selectively increasing pressure to particular surfaces when cornering to prevent contact between the pod and the tube at relative speeds 10x that of a bench grinder.

My favorite part is engineers generally worked out long distance vacuum trains as pointless and too difficult to build even with future materials like by 1875

they were generally called atmospheric railways. there are a number of good articles out there about them and they were generally promised to be the solution to the problem of running steam engines underground.

even then they were smart enough to notice that enclosing the passenger pod inside of the vacuum pipe would inevitably lead to horrific deaths. so they had the passenger compartment hooked to a piston mounted in an extremely long vacuum pipe.

unfortunately at the time elastomers were not exactly something you would get in bulk so the state of the art in sealing stuff was to slather the two components in tallow. which worked great until the rats turned up.

public reaction to the pneumatic transit system was positive and beach was all set to expand it, but it ended up in legal limbo for several years and when he finally did get the go-ahead there was an economic depression which was the final nail in the coffin. nyc actually did eventually build a medium-sized series of pneumatic tubes under the city to ferry mail between post offices that was in use all the way up to the 1950s.

He was also in financial trouble beforehand, and hadn't really worked out the methods of handling dozens of stations and miles of track, as would be necessary.

Also the post office systems were just simple pneumatic tubes like many hospitals still use. Paper and parcels don't much care about oxygen and noise levels.

Is there a reason nobody's proposing this now? Like why not just have the locomotive in the vacuum tube and have the things that need to go in/out in a non-vacuum setup.

I'm guessing it's some reason other than the cost of building two tracks.

there's two different concepts here

first is a pneumatic tube system, or pneumatic railway, which uses pressure differentials in the pipe to move stuff around. that's the 19th-century idea, and the one where they proposed two tubes so the passengers wouldn't suffocate. it's not particularly fast. its reason for existence is that you can theoretically power the whole system with a big compressor/pump at each end, and the lines are just dumb pipes.

the other idea is a vacuum train, where the pipe is kept in a high vacuum and the trains are driven inside with some other method (regular electric motor, linear induction motor, maglev, etc). i think these started to be proposed in the 1950s or something. the advantage to them is that the trains can go way faster because they don't have to deal with drag.

hyperloop is an attempt at building a vacuum train, not a pneumatic railway.
