  • I’m assuming this is meant to be an example of a real-world scenario, and I suspect it would be helpful to hear the actual scenario so that we can comment on the nuances of the specifics rather than wondering if the nuances of the example are relevant or not.

    But, to take your example at face value: no, I don’t believe the expelled rose-lover is correct about the tulip lover’s club being an echo chamber. The tulip lover’s club is about tulips… it’s in the name, and that’s why it’s members gather there. The rose-lover is coming in talking off-topic to the point that the members of the tulip lover’s club have found it distracting. It’s nothing to do with an echo chamber. I would probably expel someone from my chess club if they showed up and constantly tried to get everyone to play monopoly instead.

    I successfully migrated postgres 15 to 16. I followed the general idea of the guide you posted, but I found it a little easier to do a slightly different process. Here’s what I did:

    1. docker-compose down for the lemmy instance

    2. edit the docker-compose.yml file and comment out all of the services except postgres. In addition, add a new volume to the postgres service that looks something like this: - ./volumes/miscfiles:/miscfiles

    1. edit the docker-compose.yml file and add a new volume to the postgres service that looks something like this: - ./volumes/miscfiles:/miscfiles
    2. docker-compose up -d postgres (this starts just the postgres service from the docker compose file)
    3. docker exec -it [container name] pg_dumpall -U [username] -f /miscfiles/pgdumpall20240628 (I think this will work, but it’s not exactly what I did… rather, I ran docker exec -it [container name] bash, and then ran pgdumpall -U [username] -f /miscfiles/pgdumpall20240628. The end result is a dumpall file saved in the ./volumes/miscfiles directory on the host machine)
    4. docker-compose down
    5. mv ./volumes/postgres ./volumes/postgresBAK20240628 (move your existing postgres data to a new directory for backup purposes)
    6. mkdir ./volumes/postgres (re-create an empty postgres data folder. make sure the owner and permissions match the postgresBAK20240628 directory)
    7. edit the docker-compose.yml and update the postgres image tag to the new version
    8. docker-compose up -d postgres (you’ll now have a brand new postgres container running with the new version)
    9. docker-exec -it [container name] psql -U [username] -f /miscfiles/pgdumpall20240628 (again, I think this will work, but I bashed in and ran the command from within the container. This also allows you to watch the file execute all of the commands… I don’t know if it will do that if you run it from the host.)
    10. docker-compose down

    12. edit the docker-compose.yml and un-comment all of the other services that you commented out in step 2

    1. docker-compose up -d

    Hopefully that helps anyone that might need it!

  • I think it depends on the airline. On my recent trip I noticed that American Airlines was charging to pick ANY seat. You could avoid the charge by letting it auto-assign the seat. Your idea to check in physically and request a certain seat MIGHT work, but you have to consider the timing. Most other passengers will have checked in online earlier and already have a seat assigned… If you wait until you arrive at the airport the seat selection might be limited. I like to check in online as early as possible so I can decide if I want to pay for a specific seat.

    Good luck!
