    It could be a backronym, where the meaning of something is changed after the name is selected to fit the name. I mean, the company is Chinese. I doubt that they initially chose an English-based name, but they sure could have adopted it later.

    And yes, at least according to Wikipedia:

    https://en.wikipedia.org/wiki/BYD_Company

    “BYD” is the pinyin initials of the company’s Chinese name Biyadi. The company was originally known as Yadi Electronics (亚迪电子), named after the Yadi Road in Dapeng New District, where the company was once based.[23] According to Wang Chuanfu, when the company was registered, the character “Bi” (比) was added to the name to prevent duplication, and to provide the company with an alphabetical advantage in trade shows.[24] As the name “BYD” had no particular meaning, BYD started adopting a backronymic slogan “Build Your Dreams” when it participated at the 2008 North American International Auto Show in the US.[25][26][27]

    EDIT: Ah, @ShinkanTrain@lemmy.ml already pointed this out.



  • From my /etc/resolv.conf on Debian trixie, which isn’t using openresolv:

    # Third party programs should typically not access this file directly, but only
    # through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
    # different way, replace this symlink by a static file or a different symlink.
    

    I mean, if you want to just write a static resolv.conf, I don’t think that you normally need to have it flagged immutable. You just put the text file you want in place of the symlink.


  • Also, when you talk about fsck, what could be good options for this to check the drive?

    I’ve never used proxmox, so I can’t advise how to do so via the UI it provides. As a general Linux approach, though, if you’re copying from a source Linux filesystem, it should be possible to unmount it — or boot from a live boot Linux CD, if that filesystem is required to run the system — and then just run fsck /dev/sda1 or whatever the filesystem device is.


  • I’d suspect that too. Try just reading from the source drive or just writing to the destination drive and see which causes the problems. Could also be a corrupt filesystem; probably not a bad idea to try to fsck it.

    IME, on a failing disk, you can get I/O blocking as the system retries, but it usually won’t freeze the system unless your swap partition/file is on that drive. Then, as soon as the kernel goes to pull something from swap on the failing drive, everything blocks. If you have a way to view the kernel log (e.g. you’re looking at a Linux console or have serial access or something else that keeps working), you’ll probably see kernel log messages. Might try swapoff -a before doing the rsync to disable swap.

    At first I was under suspicion was temperature.

    I’ve never had it happen, but it is possible for heat to cause issues for hard drives; I’m assuming that OP is checking CPU temperature. If you’ve ever copied the contents of a full disk, the case will tend to get pretty toasty. I don’t know if the firmware will slow down operation to keep temperature sane — all the rotational drives I’ve used in the past have had temperature sensors, so I’d think that it would. Could try aiming a fan at the things. I doubt that that’s it, though.










  • Drones are no longer super cheap. They need to survive electronic warfare and that hardening costs a lot.

    I don’t think that Shaheds need to be able to have a datalink home to operate. I remember reading about one that shot down or was crashed being found by Ukraine that did have some kind of radio, cell or Starlink or something, but I believe that that was the exception, that normally they just fly a preprogrammed path to a preprogrammed destination.

    You might be able to disrupt the satellite navigation system that they’re using, make them rely on inertial navigation. But it doesn’t have the kind of dependency that the FPV drones do.


  • Their burn rate — they don’t get consumed unless they hit a Shahed or crash or something — is going to be comparable to Russia’s Shahed burn rate, so if they can saturate the country, then things become comparable.

    The problem is that getting to that saturation point would require sticking them all over. And if Russia comes up with some adaptation to counted, you have a huge inventory that either has to be updated or might be obsoleted.

    I suspect — I haven’t been reading about them — that they have them in target cities right now, which helps — however Russia intends to get to a target, they still have to fly to the target, end of the day. However they still gotta spread them out that way among potential targets, and in addition will have less time to do intercepts. If a couple hundred Shaheds strike at once, you’ve got a coordination problem for the STING operators, so that they aren’t all trying to chase the same Shahed. If they can be intercepting them midway, that gives them more time to bring the Shaheds down.



  • Ah, yeah, that’s interesting.

    I bet that one of those would also be bad news for, say, an unwary attack helicopter; the attack helicopter can outrun it if it knows that it’s coming, but a $2,500 man-portable surface-to-air drone with a 20 km range has got to make attack helicopter crews a lot more twitchy; that’s got more than double the range of a Stinger and can maneuver around terrain.

    Hmm.

    My own guess has been that interceptor drones are probably going to need to be part of any successful counter-drone system, but for a different reason than Ukraine has been using these: because any fixed ground-based air defenses can only cover a small area. The attacker can choose their point of attack, and can concentrate their attacking drones there, whereas the defender has to spread out their defenses.

    But the STING things are pretty short range when it comes to that problem.

    Given that Ukraine’s got a solution for Shaheds, I wonder how viable it would be to operate a “mother ship” for these? That is, have a reusable fixed-wing aircraft — probably unmanned, maybe jet powered to make it faster — that can carry a load of STING drones. Act as a data relay for them, too.

    Once a mass of incoming Shaheds are detected, it takes off, flies to a point in front of them, and then drops STING drones; it could even keep flying along with a mass of Shaheds and releasing more STING drones. That gives the STING operators more time to intercept and lets Ukraine concentrate their inventory of STING drones where the attack occurs.

    Germany apparently has 600 Taurus air-launched cruise missiles.

    They apparently have a next-gen longer-range variant coming out in 2029, and are ordering 600 of those.

    If I had to make a guess, the second batch — exactly the same size — presumably is to replace the first, which means that they’re presumably not gonna need (all?) the first batch in four years.

    Ukraine apparently also requested some.

    In May 2023, the German Federal Ministry of Defence said that Ukraine had requested the missile during the ongoing Russian invasion of Ukraine.[16] In interviews in June and July 2023, German Chancellor Olaf Scholz and Minister of Defense Boris Pistorius said that Germany would not supply Ukraine with long-range missiles.[17][18][19] In January 2024, the German Bundestag voted against the supply of the Taurus missile to Ukraine.[20] In February 2024, the German Bundestag and Chancellor Olaf Scholz again expressly refused Ukraine’s request while agreeing to deliver longer range weapons.[21][22] In May 2025 newly elected chancellor Friedrich Merz made more ambiguous statements regarding Taurus, that their delivery to Ukraine was within the ‘realm of possibility’ and that the discussion about their delivery to Ukraine would not be public.[23][24]
