  • Well I think they could say that and the unit would then respond with x possible targets and the human operator would need to give the ultimate go-ahead. Point being that it would be bad if you have a bot with a machine gun and you tell it to kill everyone hostile with a gun in this area and it blasts that 13 yo kid with a fucking stick. They could identify targets, but a human would have to be the one okaying them.

    If you lose communications then you're shit out of luck. Though I guess you would have some backup system like if comms fail go back to base or hunker down etc and wait.

  • People always mention nextcloud when it comes to syncing for e.g., Obsidian, but how do people use it with mobile? They never seem to actually use the local storage for anything, meaning you can't map a local folder for use in the application (assuming it does not have the option to use cloud services). I know thay syncthing does use actual local folders, but doesn't it use a fuck-ton of battery? I remember trying it a few years back and just could not due to it being a battery hog. Also tried the fork which helped but not by much.

    I wish I could just use rsync but nooooo. Yes yes rooting is "possible", which might just break shit or you need to use some masking to hide root from application to and jesus christ why the fuck is everything so annoyingly locked down god dammit. Rant over.

    Havant tried termux + rsync tho.

  • Sure I can see it being a security feature, random USBs are not a good thing, but I feel like it is quite minor with an air gapped system, no?

    The backup is a good point. Though from this I started wondering how difficult it is to get the VM to communicate with old hardware. Like, the hardware might use some random method of actually communicating with the computer, ans getting that through to the VM might be problematic? I have no clue, just spitballing here.

  • The rant in the post has some merit to it, but the thing it sort of misses is also the reason not to use VM. It works just fine. It hasn't been updated in 20 years because it still works. It does what it says on the box. Why put it in a VM? What would you gain from it? If you need Internet just grab a laptop and have it sit next to the main computer. That way users have a much smaller chance to break something vital. Pretty much all the control computers are air gapped anyway. No updates or anything to break things you reeeeally don't want to break.

    The only case I've seen VMs being used is if the old computer breakes and you can't really find something that's compatible with old-as-fuck software om bare metal. I work in a cleanroom and we got sooo many systems that are windows 95 or older (DOS anyone?). Electron microscope, etching systems, probe stations

  • This is interesting but issue with Perovskites is not efficiency per say, but it is degradation. It is a cool tech but their lifetime is measured in months and not decades. Here's one study for instance. Perovskites might be where the tech is going but there are still major hurdles to overcome.

  • The materials that do the absorption are not effective across the entire wavelength spectrum of the sun. They can only absorb at a certain wavelength range, but the spectrum range of the sun is very wide.

    Edit. Also other reasons, like recombination rate where the photon hitting the panel generates an electron-hole pair which is then collected and used for evegy, but electrons and holes tend to want to recombine, after which we cannot use them for evergy. We want this rate to be zero, but it never is, it is a probabilistic process. So even if you can absorb everything, you can't utilise everything you absorb.
