  • adding PPAs or RPM repos, or installing things from source, I’d say that number is a lot higher than 0.

    Nothing wrong with that. Unlike docker that’s cryptographically protected toolchain/buildchain/depchain. Thus, a PPA owner is much less likely to get compromised.

    Installing things from source in a secure environment is about as safe as you can get, when obtaining the source securely.

    Docker contains that nonsense in a way that’s easy to update.

    Really? Ist there already a builtin way to update all installed docker containers?

    What’s uneasy about apt full-upgrade?

    Package managers don’t provide a sandbox.

    I didn’t say that.

    average user who doesn’t run updates consistently, may add sketchy dependencies, and doesn’t audit things would be better off with Docker.

    That’s false.

    but they’re less likely to cause widespread issues since each is in its own sandbox.

    Also false. Sandbox evasion is very easy and the next local PE kernel vulnerability only weeks away. Also VM evasion is a thing.

    Basically one compromised container giving local execution is enough to pwn your complete host.


  • in the same way that installing a malware-laden executable isn’t an OS problem

    except no one is doing that. Every major distro hast mechanisms for software supply chain security and reproducible builds.

    Do your due diligence, especially if you’re not a developer and thus looking at the Dockerfiles is impractical.

    You’re on to something here. If you automate that process, you end up with something we call a package manager.

    it’s likely blog posts and users that are at fault.

    Exactly. And sincer reviewing Dockerfiles is impractical, there’s no way docker prevents you from shooting your own foot. Distros learned that long ago: Insecure default configs or injected dependencies are a thing of the past there. With docker, those get reintroduced.



  • This entirely misses the point of Docker.

    It’s just pointing out the risk of letting someone you don’t know with no legal obligations setup your complete environment.

    How likely

    Probably as likely as someone cracking your really secure ssh password. Still, any sane expert will recommend disabling password auth.

    I only pull containers based on some official project.

    How do you know they weren’t compromised?

    but I don’t see anything here about Docker itself being a problem

    The problem is that rootless docker is a pain and no one does it. Privileged software sideloading other software is a huge risk.

    That risk now became an incident. Even if you’re not affected, the risk still remains.







  • I’m no expert either but I never got the idea of a new universe popping up everytime. Do other universes also cause popups of new universes or just ours? That’d escalate quickly :-)

    I thought it goes that there’s already infinite universes existing from the big bang on. Otherwise universes would be created without big bang. (The new universe would just pop up and you’d still believe it was created by the big bang but there never was one)

    Also I’m not sure if laws of thermodynamics had to span accross universes. Take two theoretical perfect vacuum/radiation sealed boxes you put an energy source into. There’s no way to communicate between boxes. Each box had it’s own entropy and state of energy. Both would obey the laws of physics while being separate “systems”.

    That thought experiment wouldn’t work, if new boxes had to pop up if one of the boxes wanted to.





  • When you refund a mattress they just surface clean it

    yuck. I doubt that. It’s manual work and far more expensive than a machine.

    but getting them dry would be a challenge

    seriously? I mean, there is a chance no such service exists in your town. Bad luck then. But there is close to zero chance it doesn’t exist in your country.

    What do you think hospitals do? (Or good hotels, as mentioned). Source: Worked in an elderly home that used such a service regularly.

    Here’s an image of such a mattress washing machine.

    They work.


  • That’s not true. All mattresses except the cheapest foam ones are washable (they are, too but they might change properties then). But why get a used cheap one?

    There are mattress washing services with giant washing machines that are used by hotels. Ask hotel staff to find one.

    You can’t get rid of most of the build-up.

    You actually can get rid of all the buildups. Just like with clothes. Also don’t think sellers throw it away when you refund a mattress - they wash it and sell it again.




  • Some things basically come for free when they were used. Washing machine, stoves… Disassembling them to fully clean them takes a day or two, but it’s still faster than buying new and chances are good, someone wants to get rid of their high quality stuff near you and will give it away for cheap if you “dispose” it for them.

    You can even wash a mattress for a few bucks. If it’s good quality, a decade old used filthy mattress can come out like brand new.

    People finding that gross or poorish are the reason, stuff is so cheap
