A software developer and Linux nerd, living in Germany. I’m usually a chill dude but my online persona doesn’t always reflect my true personality. Take what I say with a grain of salt, I usually try to be nice and give good advice, though.

I’m into Free Software, selfhosting, microcontrollers and electronics, freedom, privacy and the usual stuff. And a few select other random things, too.

  • If you google it, you’ll find lots of similar questions for O2. I think you have to contact their customer support and get that activated once.

    And have a look at your IPv4 and IPv6 addresses. Sometimes you can do it via IPv6 already, just not over IPv4 because there is some translation in the way. (In case they want too much money to give you a real IPv4 address.)

    Maybe you can try if you can open your FritzBox UI from the outside with your my.fritz address. I think that has IPv6 and a port forward in place (if activated).

    And btw: It’s perfectly fine to do it. People need storage and online collaboration. Access to their data while away.

    The visuals are the best thing I’ve seen today 😆

    I’m pretty sure someone wrote the lyrics here or at least put some good amount of effort in. With my experiments it was far off from that kind of rhymes with ABAB schemes and rhyming a word in the middle of the line.
    [Edit: In the video comments they say the text is AI generated, too!]

    Sure, back in the day and without AI it was different: https://m.youtube.com/watch?v=9sJUDx7iEJw (RMS singing the Free Software Song).

    (I myself don’t have any issues with AI singing and doing music. No one can replace my favorite artists and bands anyways. And I wouldn’t notice if they added yet more soulless and dull pop to the radio program. Because that’s already pretty much there is to it.)






  • I’m not sure if 3-4 times a day is a lot. I had computers (especially laptops) which were way more aggressive with spinning up and down the disks. Maybe you can look it up. A decent (enterprise(?)) hdd should have some datasheet available including info about how often you can powercycle or spin them up/down.

    And I wouldn’t wake up disks deliberately. If you don’t mind the 5-10s waiting, you can just spin them down at the end of the day and leave them that way. The next day they’ll either spin up on first access, or they won’t. And save that one cycle. I’m not sure though if you can change the spindown timeout during the day without also waking it up. I mean you could run a script that spins them down at 22:00 and sets the timeout to 1h, and at 07:30 you run a script to keep them awake for a 6h period. But you’d need to test if changing that setting wakes them up. Or I’d rather not run a script like that. Sometimes executing hdparm spins up a disk, even if unnecessary.

    That is indeed a good question. Is this something RAID is bothered with at levels 0 and 1? I think in this case it’s the job of the filesystem to care for that. But you should probably let the periodic task run that does scrubbing like once per week. You could also experience other issues than just bitrot. For example bad sectors and one of the hdds slowly degrading.

    In the end I don’t think a RAID1 can do much about bitrot and other RAID woes. There are no checksums or anything to correct for that. You’d probably need some other technology for that. But it’s probably the same for a ZFS mirror. And everything better than that needs more than 2 hdds.


  • Yes, as the other people pointed out, that’s what I mean. The standard Linux software RAID (also called MD RAID)

    It’s proven, battle-tested, pretty robust and you don’t rely on any specific vendor formats or any hardware for that matter. The main point would be to keep it simple. You could use BTRFS or ZFS or all kinds of things. But it only introduces additional complexity and points of failure. And has no benefits over a plain mirror (what the RAID1 does) if we’re talking about just 2 devices. At least it served me well in the past. Contrary to cheap hardware RAID controllers and also BTRFS which also let me down once. But a lot of development went in to that since then and the situation might have changed. But mdraid is reliable anyways.




  • I’m pretty sure the cryptographic parameters to generate a public key are included in the private key file. So while you can generate the other file from that file, it’s not only the private part in it but also some extra information and you can’t really change the characters in the private key part. Also not an expert here. I’m fairly certain that it can’t happen the other way round, or you could impersonate someone and do all kinds of MITM attacks… In this case I’ve tried it this way, changed characters and openssh-keygen complains and can’t generate anything anymore.
