Out of a reflex of distrust, I refuse to participate in any kind of loyalty program of the outlet of the large retail store around the corner.

I tell myself that by refusing to join the loyalty program (which basically comes down to scanning an anonymous loyalty card every time I make a purchase), I prevent them from adding my correlations (what products I buy, in what combos, at what time) to their data.

But since I normally pay by card, I guess they can (and do) already do that with my bank account information?

If I would pay with cash, they can still see those correlations per purchase, but they can't track my purchases over time?

Does anyone know if there are any companies/organizations that offer the possibility to sail the Atlantic by boat as a passenger (so not as a (more or less) experienced crew member). Are there any? Or announced plans or something like that?

(I'm not talking about being a passenger on a large cargo ship. I'm curious about the possibility to cross the Atlantic with a low carbon footprint).

After watching this video I am left with this question.

The video ultimately claims that humans will not disappear, but doesn't do a great job explaining why.

Correct me if I'm wrong, but for the (or a) population to be and remain stable, the total fertility rate needs to be equal to the global replacement rate (which recently was 2.3).

And since the total average fertility rate appears to be currently at this 2.3, any drop in the fertility rate in place A would have to be compensated with a rise in the fertility rate in place B (assuming that, at some point, we would like to stop population decline)?

I guess one way for a population to remain stable, while women are having fewer than 2.3 children, would be to have fewer men? If a population has 100 women and 10 men, each woman would only have to have on average (a bit more than) 1.1 child? (Which would of course also require a collective form of prenatal sex selection.)

I realize that would be bonkers and unethical. Just wondering out loud.

What could be reasons for my rsync, which is syncing two remote servers through ssh, to slow down over time like this? It keeps happening. How to check what is the bottleneck?

Hi all, sorry if this has been asked/discussed before (I couldn't find any directly overlapping posts):

I have been running the Nextcloud snap now for quite some time, and although things have run quite smoothly, I never really managed to properly back things up.

I make weekly backups of the database, config and data, but it's very hard and time consuming to glue these elements back together. And as they say: when you can't check whether a backup works, it's not really a backup.

I have been experimenting with KVM/qemu lately and things look pretty great. The idea of simply backing up the entire OS that runs Nextcloud (a backup that you can easily deploy/run somewhere else to test if it's working) sounds very attractive.

Reading around, however, tells me that some of you recommend running the Nextcloud docker (instead of a VM).

My questions:

1. What would be the advantage of running Nextcloud as a docker, instead of within a VM?
2. What would be a sensible way to have an incremental/differential backup of the VM/Docker?
3. The storage usage of my Nextcloud instance exceeds 1TB. If I run it within a VM, I will have to connect it to a 2TB SSD. Does it make sense to add the external storage space to the VM? How does that affect the ease of backing the full VM up? Or (as I have read here and there) should I simply put the entire VM on the external SSD?

I recently asked an admittedly controversial question about the veracity of a Mastodon account. Some people understandably took offense, while others were willing to exchange thoughts. It was a conversation of about 13 comments.

I now find the post is gone. I can't find any message in my inbox about any removal. Now I understand that we cannot expect mods to provide elaborate justifications for all their decisions, and I understand that they (and admins?) are the final arbiters (although in this case I think it was a bit drastic, also considering that I there was a diversity of perspectives). But shouldn't participants in a post be notified or something? With an automatic notification? When a post is deleted?

I would like to be able to use the command line (curl) to get a list of communities I am currently subscribed to.

I know that there is a full-blown API, but it only briefly covers what it is possible with simple a curl request, and most of it seems to refer to an API that runs in javascript (which seems excessively complex for what I want to do?)

A simple curl request like this seems to work,

curl "https://mander.xyz/api/v3/community/list" | jq

But I wouldn't know how to make it list only communities that I subscribe to? Does anyone know more?

What is happening here? Spanish not allowed?

I think there are good reasons to not let corporate interests join the space we built to escape them, but I guess every instance is free to (de)federate with whomever they want.

So let's say my instance (mander.xyz) defederates from Meta but another Lemmy instance that meander.xyz federates with (let's say "misguided.ml") does not. What happens when someone from Meta comments on a post from misguided.ml and others from misguided.ml comment on that comment? Will I see the comments on the meta comment, but not the original meta comment itself? Or will I not see the entire thread?
