Usenet is a bit like the fediverse, it has tons of different servers that all talk to each other, and the admins of each server decide which groups it carries. So it you use a server outside the jurisdiction of the police you’re afraid of you’re somewhat anonymous.






Yeah that’s completely normal, looks absolutely fine to me. For more info on how linux uses memory I suggest reading https://www.linuxatemyram.com/
To add: that link suggests looking if your swap usage is changing. Linux is quite happy to stuff some memory that isn’t actually used in swap. If it was right about it not being used you should see the swap usage not changing much, so your SSD isn’t really being used either apart from the initial swap-out. If your swap usage keeps fluctuating wildly there is more going on which might warrant further investigation.
