    toProgrammer Humor@lemmy.ml•Basically the extent of my IPv6 knowledge
    12•3 days ago

    Well good news. Because ipv6 has a thing called privacy extensions which has been switched on by default on every device I’ve used.

    That generates random ipv6 addresses (which are regularly rotated) that are used for outgoing connections. Your router should block incoming connections to those ips but the os will too. The proper permanent ip address isn’t used for outgoing connections and the address space allocated to each user makes a brute force scan more prohibitive than scanning the whole Ipv4 Internet.

    So I’m going to say that using routable ipv6 addresses with privacy extensions is more secure than a single Ipv4 Nat address with dnat.

    toSelfhosted@lemmy.world•Networking Dilemma
    6•5 days ago

    I think people’s experience with PLE will always be subjective. In the old flat we were in, where I needed it. It would drop connection all the time, it was unusable.

    But I’ve had them run totally fine in other places. Noisy power supplies that aren’t even in your place can cause problems. Any kind of impulse noise (bad contacts on an old style thermostat for example) and all kinds of other things can and will interfere with it.

    Wifi is always a compromise too. But, I guess if wiring direct is not an option, the OP needs to choose their compromise.

    toLinux@lemmy.ml•Disk space counted twice on root folder?
    30•7 days ago

    OK, one possibility I can think of. At some point, files may have been created where there is currently a mount point which is hiding folders that are still there, on the root partition.

    You can remount just the root partition elsewhere by doing something like

    mkdir /mnt/rootonly
mount -o bind / /mnt/rootonly

    Then use du or similar to see if the numbers more closely resemble the values seen in df. I’m not sure if that graphical tool you used that views the filesystem can see those files hidden this way. So, it’s probably worth checking just to rule it out.

    Anyway, if you see bigger numbers in /mnt/rootonly, then check the mount points (like /mnt/rootonly/home and /mnt/rootonly/boot/efi). They should be empty, if not those are likely files/folders that are being hidden by the mounts.

    When finished you can unmount the bound folder with

    umount /mnt/rootonly

    Just an idea that might be worth checking.

    toAsklemmy@lemmy.ml•The meaning of life
    3•8 days ago

    I think we should qualify the question. I think I’d like to hear a reason for society as a whole to exist that is reasoned and has a firm basis in logic and has no emotive or circular reference.

    Because I cannot see the point of it (and I’ve been accused of being a pessimist, depressed and worse for expressing this opinion). So, I would really like to hear an actual reason for us all to be here.

    toAsklemmy@lemmy.ml•Do you prefer Gaming PCS or Gaming Laptops?
    2•12 days ago

    Both, each have their place. I have a desktop in my office. Decent recent spec and kept fairly up to date.

    Laptop I have a reasonable “gaming” spec in the lounge we both use it.

    The laptop will always be a compromise. You cannot shift the dissipated heat from a full power gpu at all in that form factor, and most cpus are going to also be lower power editions because they need to work on batteries as well as connected to power. But they’re still for sure usable.

    Desktop will always outperform. Even the stock cpu and gpu options will perform at a higher tdp, and you can usually improve cooling in a big case to either improve stock boost frequencies, or over clock.

    Physics is the limiting factor for laptops, both in terms of power delivery, and heat dissipation.

    toWorld News@lemmy.ml•U.S. Considers Expanded Nuclear Arsenal, a Reversal of Decades of Cuts
    5•19 days ago

    Yeah. The 7.5 times (or is it 9.5 times, I forget) thing that has been thrown around since the cold war days never rings true to me.

    The primary and secondary strikes for both sides will take out people living close to either a military installation or a major city.

    Also there’s no way even a world war would involve every single country and every single island. There’s no way human life would be entirely obliterated. Most us posting here, perhaps. Certainly I’d likely be taken out in the second or third wave (close to London and also close to a military base). But life would go on.

    toAsklemmy@lemmy.ml•When was the last time you bought a paper map and why ?
    2•19 days ago

    GPS Navigation didn’t become widely available at a decent size until the mid 2000s I would say. I remember for sure I had GPS navigation on a laptop which was just as ridiculous as it sounds in around 2002-2003.

    The GPS was a PCMCIA card with an aerial you put near the windscreen. The software would just stop showing a map when you went faster than 50mph or so, and only provide basic instructions and your speed. Buying a laptop charger that plugged into the cigarette lighter socket wasn’t as cheap as it is now either.

    Needless to say, it was a novelty thing. The main problem with paper map navigation when driving is, you really need to compress the instructions down to something you can remember if driving on your own. Since you need to stop if you lose track of your route. I don’t miss that to be honest.
