  • Fair. But that’s not really earth scale thinking in my book. It’s more our best understanding based on what we know.

    I know of these theoretical work arounds. They’re more mathematical models that say if such a thing as negative mass exists, then we might be able to go faster than the speed of light. Issue is that the model does nothing to show that negative mass exists.

    That and everything we know shows that it does not exist. If it did I would be incredibly happy. It’s just wishful hoping at this point though. We don’t even have a model or theory that shows how negative mass could exist. We only have theories that show what could happen if it did exist.

    It’s like saying hm we know how F=m*a works. What could happen if we set m to a negative number? Yah in the math we can but that does not mean we can in reality.





  • A drop in the bucket isn’t event close to a good understanding of how big space is. A satellite in the ocean is grossly misleading when it comes to the scope of space.

    Maybe a single O2 molecule in the ocean might be closer but even then that’s not even close to the scope of space.

    Space is big. So big that the light cone of our “pollution” can’t physically interact with most of it even if we did our best to “pollute” as much as we can and some alien species did their best to find that “pollution”. Space is so big that physics dictate the impossibility of our “pollution” interacting with most of space.

    Fun fact this is why the chance of aliens visiting us here on earth is basically 0.

    You can’t use earth scale thinking, that’s how big space is.

    This all being said we should do our best to not pollute the earth. We should use earth scale thinking when it comes to earth.











  • If the service is already running it has to be stopped as a system service and run as a user service. In order to ensure that the service inherits all the correct permissions / acls / se linux policies the service needs to be launched from the limited permissions context.

    With the systemd approach you’re not just passing a control handle around. You’re ensuring the process is running under an appropriate security context.

    If you want to let multiple users manage the user systems service, I would probably go with sudo and systemd user files. You could create a group which has sudo access etc. The important idea is that an unprivileged user controls an unprivileged service.





  • There is a lot here but I think the most important thing is that docker containers should always be disposable. Don’t put any data into the container ever.

    All of your data and configuration should be done in volumes. Local disk to inside the container is all you really need.

    By doing this you make updating any given docker container easy as just pulling the newest tagged version of the container. If you are using docker and not podman you can use tools like watchtower to do this automatically.

    As for what distro, it depends on your goals. Do you want to learn and improve your skills? Stick with Fedora or Rocky or Debian or openSUSE. I recommend learning the command line as you go, but if you want a nice UI openSUSE has Yast which is a very robust tool.

    If you want to just have a home NAS but don’t want to learn that’s a different question. In this case if you’re getting a proprietary NAS anyway you could just get one that supports docker (like synology) and kill 2 birds with 1 stone.
