  • No. It’s not a magic invisibility field inside. It’s a magic object that works only on living “intelligent” creatures. It also doesn’t work the same on different races. Only humans (hobbits are a subtype of human in Tolkiens lore) turn invisible. And because it’s magic it also turns their clothing etc invisible. So either Frodo and his poop is invisible or nothing is.

    By design nothing in the chain can be altered. But of course you could have a block indicating “person X is now person Y”. But you can always read that Y was at some point X (and at what point the change happened). That would not be good, as it would be a public ledger of all trans people. It would also make things like witness protection impossible because inserting a block “today in 2024, person W was born in 1974” is very suspicious






  • Can you verify the software running on an instance is the same as the one in the source code repository? You can’t. Can you verify the instance isn’t running code to read passwords from your login requests even if the code is the original open source code? You can’t.

    That’s why (and for other reasons) you should never use a password for more than one site/service/instance.

    Lemmy admins (admins in the Lemmy application) probably can’t read your password. But everyone with admin rights on the server operating system can.




  • The thing that confused me when first learning about docker was, that everybody compares it to a virtual machine. It’s not. Containers dont virtualize anything. They take a (single) process from the host OS and separate that into its own environment. All system calls, memory access, file writes etc are still handled by the same os (same kernel). However the process is separated both on the file system and process level. It can’t see other processes outside of the container and it also doesn’t see the real filesystem. It sees a filesystem provided by the container. This also means it sees different file and user permissions. When you run a alpine Linux docker container on an Ubuntu system, the container only containes the (few) files for alpine but no Linux kernel no desktop environment. A process inside that container only sees the alpine files and not the Ubuntu files. It also means all containers see a filesystem independent of each other and can use libraries and dependencies of different versions (they are only files after all).

    For administration it makes running complex services easy. You define how to setup that service (what base Linux distro to use, what packages to install, what commands to run, and how to start the process). You can then be save to assume the setup of that service did not interfere with the setup of any other service. “Service 1 needs a certain system wide config changed? Service 2 needs that config in the default state? And both need a different version of the same library?” In containers you can have all at the same time because they each see a different version of the same config and library.

    And all this is provided by the kernel itself. All docker does is provide an “easy” way to create and manage containers but could could do all of that using chroot, runc and a few other.

    As a note, containers usually don’t come with systemd as they don’t need an init system. You would run the service directly inside the container and then use systemd outside the container to make sure the container is started/restarted, or just docker as it can already do that.

    I found a great article demystifying containers recently







  • One caveat about the Olympics is, you can’t just choose to compete there yourself as an athlete, even if you are world class. You have to be part, and chosen by, a national organisation. So even if the Olympics allow trans athletes, as long as most countries don’t, there won’t be trans athletes any time soon. I agree on the rest, I just don’t think the Olympics will be a forerunner in terms of trans representation.
