  • Frisbee golf. It’s cheap, fun but challenging, and outdoors. Worst case scenario, you go on a long walk and bump into some interesting people. If you’re in a medium sized city or larger, there is probably a course and league near you.

    The culture is generally very polite and fun to be around. Lots of harmless stoners and 30yo bearded people with beers in hand. In the south there is starting to be some influence from megachurches using it as an enticement, so I’m not sure if it’s “cleaned up” a little more down there.









  • Agreed. I have more hours in DCSS than any other game.

    I don’t think it’s totally fair to call it ugly either. It’s a masterpiece of efficiency. The ASCII looks messy to some people, but after a while you just see right through it; purple Y = catlobe gtfo etc. Plus the upside is that it’s extremely clear at a glance what is going on because you don’t have complicated sprites everywhere. And the handmade vaults that get rolled into the procgen are often really nice looking and give the world a lot of character.







  • If you have a little technical skill, you can set up your own raspberry pi ads-b receiver really easily. Just need the raspi, and SDR dongle, and an antenna. Floghtaware provides a flash image for the OS. If you feed them data, you get a free premium subscription. I used to use it to get alerts when the state patrol speed trap aircraft were taking off so I knew not to speed on a long interstate commute.



  • There are a few kinds of steam!

    Wet (unsaturated) steam: this is probably what’s coming out of the instant pot. It’s gasified water mixed with tiny particles of liquid water. Industrial processes do not want wet steam in their systems. They have machinery to separate the liquid out. If that liquid water settles out inside a pipe and blocks it, it’ll go shooting down the pipe like a bullet and cause damage to whatever is at the end of the line. If the droplets get into turbomachinery, they’ll tear up the turbines. Adding additional heat will not increase the temperature, but will get consumed by the phase change to evaporate the remaining water and change the wet steam into…

    Dry (saturated) steam: this is precisely the point when all the water has been evaporated. If you remove heat, it will start to condense without changing temperature. If you add additional heat, it will increase the temperature of the steam, because there is no water left to evaporate. This is useful because changing phase between liquid and gas consumes/yields a ton of energy, and that happens at a constant temperature. So if you need to transfer heat from one place to another, then saturated steam is what you want. Adding heat to saturated steam gets you…

    Superheated steam: at this point you can conceptualize water as a gas. Intuitively, it works just like air or nitrogen or whatever. Pressure/temp relationships act like you’d expect from your everyday experience, because you’re far enough above the gas-liquid phase change temperature that you don’t have to worry about condensation getting into your equipment. If you want to use steam as a working fluid in turbomachinery or something, then you want superheated steam.

    All three can hurt you badly, but inadvertent contact with superheated steam will fuck you up or cause irreversible death.
