I now understand why Lemmy is called “link aggregator” software

Having multiple communities in different instances for the same topic is a controversial topic that I haven’t yet settled on an opinion about. However, what I’m talking about here is that the content for the same community shows different across various instances. That seems very broken to me

I understand how instances that don’t federate with another instance won’t show content, but I’ve checked a bunch of instances. Could it be that beehaw, lemmy.one, reddthat, lemm.ee, and feddit.de have all defederated from lemmy.world? They all have a different mix of content

Here is their post about it:

Yeah I saw that about beehaw, so that’s not unexpected. It’s actually what prompted me to look at how the community appears differently there, and then to look at how it appears elsewhere. Pick any lemmy instance and look at the sysadmin.world community from it, and it looks different than lemmy.world. I just looked at https://reddthat.com/c/sysadmin@lemmy.world/ and there too it only shows 6 comments.

Pick any community and any number of instances and look at the community from several instances, and I see differences. I thought federation would make the same content show everywhere that is federated.

If you port forward to your Pi, only your Pi will be exposed. But, if your Pi gets pwned, it can in turn attack anything next to it. Safest is to isolate the Pi on it’s own subnet or a DMZ if your router has the functionality.

Of note, many home ISPs block standard server ports like 80 and 443. You might need to use non standard ports like 8080 and 8443
