time for some kind of anonymizing location data sharing service, peer to peer or federated protocol? that might be interesting, or sketchy, not sure which.

Pretty sure you can download the maps ahead of time, GPS doesn't require data, then upload the fixes when you get home.
Go map keeps crashing for me, does it for you?
I've been using Go Map! but it keeps crashing... Maybe I'll try Streetcomplete if it's on apple.
Do it! it is easy to do at home! Just wear some gloves and safety glasses, those jars can easily shatter during the heating process if you use too hot of a heat source. I recommend a glass top electric stove, or put some kind of metal plate between your jar and the burner to help spread out the heat. Once you seal the jar, take it off the heat right away, so it doesn't build pressure. I boiled mine for a few minutes before sealing to try and get some of the devolved gasses out, and lightly set the lid on top to help the steam push out all the air.
It does. And Firefox is my default browser app.
It's the only browser I have installed besides Safari, and my default browser but instead of just opening the link with my default browser, it advertises these other browsers to me and makes me click 'Default browser app' by default. wtf I'll be turning that off, should have never been a feature.
Yes definitely. The pressure will drop along the vapor pressure curve all the way to the triple point, gently boiling all the way if you remove the heat from the vapor and not directly from the water.
Anything for posterity
Exactly. it was bottled at atmospheric pressure while it was boiling, so 1 atm and 100 degrees C. Check this graph to see the relationship between the water's temperature and it's pressure in the jar (since there is no air, only water vapor). If the vapor is condensed, then the pressure drops below the curve on the graph, that is, the pressure in the jar is lowered below the vapor pressure of the water. Any time the pressure is below the vapor pressure, the water will boil, releasing vapor, until the pressure is equal to the vapor pressure. The pressure does not become negative, it is still positive, just lower than the vapor pressure at the given temperature. You can get below the vapor pressure curve by changing the temperature too, which is what we usually do when boiling water at a pressure near 1 atm (760mmHg)

(1 atmosphere is ~760mmHg)
a slight aside, there is an important difference between the total pressure of the air, and the partial pressure of water vapor in the air. Inside the jar, the two are equal, but in a dry location (not humid) the partial pressure of water vapor is usually less than the vapor pressure of water at that temperature, but since the total large pressure of the atmosphere would not allow a pocket/bubble of very low pressure water vapor to form inside the bulk water, the water cannot boil, but it will evaporate at the surface anyway until the partial pressure of water is equal to the vapor pressure (very humid).

This community is dedicated to the most interesting engineering/science projects and papers out there. Lots of youtube videos, along with scientific papers ( <3 https://www.sci-hub.st/ <3 ) and book recommendations that are not only Interesting, but also Rigorous to some degree, without being exclusionary.

More people ought to feel allowed and able to think about ideas that are worth thinking about!
There is one more step once you found an community you'd like to subscribe to. Take the link to the community (something like https://lemmy.fmhy.ml/c/freemediaheckyeah ) and copy it into your home instance's (the one you've made an account on) search page. for me it looks like this:
Sometimes, it will say "No Results." Just wait a view seconds, and maybe try to refresh. The server it mostly likely retrieving some posts and comments for the first time. Eventually, it will show up, click the result, and you'll be directed to something like https://lemmy.sdf.org/c/freemediaheckyeah@lemmy.fmhy.ml (with your home instance's domain in place of mine) and you can subscribe from there.

That's a super interesting project. For anyone else, the project overview has some great system level diagrams:
