  • As a fully functional adult, I’ve been eyeing off light up shoes for years. So far, all I’ve seen is gimmick shoes you wouldn’t wear for more than an hour, so I make do with fluorescent shoelaces instead.

    This seems like fun, though I’m not sure if I’d be game to walk up a set of stairs on them, perhaps I’m not keen on breaking something when I’d invariably trip and fall.




  • How would you suggest I respond in the future?

    We have a person, claiming that CUPS doesn’t work and they now uninstall it on every installation.

    There is no context, no data, no information that suggests what the issue is, what they tried, when this occurred, on which platform, under which conditions.

    In other words, the user was essentially saying “CUPS sux”.

    Having used Linux as my main system for over 25 years, that sentiment did not match my own experience, does not help anyone, not me, not the user and not the OP who was trying to solve a problem, let alone anyone else reading along.

    I responded accordingly.












  • There’s a common but persistent misconception that Docker is like running a virtual machine. This is understandable but incorrect.

    A better way to think of it is as a security wrapper around an untrusted process.

    If you look at your running processes whilst a container is running, you’ll see the processes inside the container running on your “host” machine - remember, it’s not a host - guest situation.

    There is no relationship between the user inside the container, unless you start mapping the UID and GID.

    The only exception to this is the root user which shares the UID/GID with the actual root user.

    See: https://www.howtogeek.com/devops/why-processes-in-docker-containers-shouldnt-run-as-root/

    Edit: I suspect, but don’t know for sure, that the root user inside the container is actually the same user as the one running the Docker process, which is typically the root user on the “host”.
