  • For anyone in that spot of being savvy-ish but having fellow users that finally got used to plex:

    A work around is Xteve and owncast. I was successfully able to make an owncast broadcast into a “DVR channel”.

    Its cluegy but it does work. My tech level in this stuff is spotty. I’m used to stacks of tech but more for physical control systems (NOT consumer facing). But I was able to get that to work.

    Edit: little bit of clarification: Xteve will let you add DVR to your plex server. It’s possible to tie owncast into Xteve. That allows users to cue into a “DVR” channel which is kind of “simulcasting” whatever you’re pointing owncast to. In my case it was a screen share of sportsball, but it could be whatever.


  • I love this. I have a box I’ve been wanting to move to a family members place because they have fiber and I don’t. They’re heavy users of the plex server I have on there, so they’re happy to host it, but if I ever had issues around anything boot related I’d be down until I could physically get there.

    This would also be awesome for troubleshooting some RasPi stuff where I kind of want the DE every now and then but mostly let it run headless.



  • it is, (although the design is slightly different, you couldn’t just run the motor on an AC backwards).

    Heat pumps are better for the environment because it’s (usually) more energy efficient to extract existing heat than create it. Heat-pumps get more heat per unit energy spent than resistive heat (like electric radiators) because they’re not creating the heat, they’re just moving it.

    Natural gas still kind of wins out, but that has the issue of constantly needing more natural gas.

    The most environmentally friendly play would be, if you were like on a space station or something: Imeaditley stop producing more natrual gas, use up whatevers left in reserves, then install heat pumps. But of course that’s not how things work so we’re transitioning now.

    edit: re: AC not being good for the environment. AC isn’t the problem, just the power is. So it’s just seen as a luxury as opposed to necessity, although obviously that’s starting to change.


  • As others have said yes, thats an air conditioner, but to expand: that’s why the outside of an air conditioner (either one of the big ground mounted ones outside or the window ones) gets hot while it’s operating. You could technically just mount your window AC backwards.

    To expand further, that’s part of why heat-pumps weren’t in expanded use for a while. In the summer you’re extracting hot from the room and putting the hot outside, so your heat exchanger is hot. But in the winter when you’re extracting heat from outside and putting it inside, you make the heat exchanger outside more cold. So cold, infact, that icing becomes an issue, and when it ices over it’s less good at extracting heat. There are some neat tricks modern heat-pumps use to avoid icing over their outside heat exchanger (including running backwards to extract heat from inside and heat up the coils for a bit).

    It’s also why you saw early adoption of heat-pumps in areas where people might need both heating and cooling, but it didn’t get bitter cold.

    Another way this is avoided in some cases is to simply bury the heat exchanger to a depth below the frost line, where it can’t freeze. Then you can add/extract as much heat as you want. That’s geothermal heating/cooling. In some cases geothermal may be passive (ie: you’re just circulating a fluid and temperature you get is what you get), but it’s real strength is as a heat exchanger.

    In fact, with the ground being able to accept/source as much heat as you want, you could actually place the “topside” exchanger in an area where you weren’t trying to control the temp, and take advantage of the temperature difference to create power. Thats geothermal power. However, the efficiency and payback of that is based on the difference in temperature, which is why you only see it in instances where there’s some natural source of higher temp heat underground. I suppose geothermal power would work just as well with a natural source of low temp cold (like the opposite of lava), but I’m hard pressed to imagine what that would be.


  • for posterity: I don’t think that was it (although it does seem to be a common issue especially when you have an SSD). I never did try initramfs modification (not correctly anyway, I don’t think).

    Problem was resolved by purging nvidia, and installing the driver manually. There also appears to be an issue with the secure boot signature, so for the time being I addressed it by disabling secure boot. Another day’s problem. edit: so it was likely never a race condition issue, it was likely secure boot rejecting the keys. It should be easily resolvable, even if I need to purge again, reinstall, and put the key in the proper place, but I’m ok for now given whats on this machine, what it has access to, and other shit I have to do.

    edit: I forgot, I confirmed that the system is, infact properly utelizing the driver to get the most out of the card.
