I doubt it was a real wallet - most likely it was just a scam exchange that would prompt you to send cryptocurrency “for verification” before you could try to withdraw them.
The idea was already exploited on prnt.sc, where it is possible to try bruteforce screenshot ID and find other users public screenshots - https://splashdot.github.io/scam1/

Your docker install is too old and it doesn’t support that docker-compose version, you probably should update your docker to more recent one (are you running debian 10 on default repositories?), or you could remove logging references from file (these x-logging lines in each service and whole section on top of file)

I’m using x2go to access my remote KDE session for a couple of years now - it runs over ssh tunnel and supports audio, generally im pretty happy with the performance, the only disadvantage that I come across is a lack of mobile app and the session sometimes can be a bit flakey

Close enough! I’m using a HP z230 SFF, not as small as those 1L USFF, but pretty practical for a small homeserver, have a couple of PCI-E slots to expand, can hold 2x HDD (if you count replacing 5,25 optical drive with a tray) or multiple SSD wherever they fit. Pretty happy with this build, day-to-day it draws about ~18-50W from the wall, depends on load.

No, i didn’t, but i think it should also work over cloudflared

My instance is actually behind cloudflare and it works fine, but remember that it would be possible to “expose” ip of your server due to federation, as your server will talk to other server (directly, that traffic won’t go over cloudflare), so if you are paranoid about that, i would recommend setting up a wireguard tunnel to cloud instance, and forwarding the traffic that way, or just setup the lemmy on that instance

Proxmox itself is pretty lightweight, and yes, i’m also running other VMs and LXC containers (not much, about 9 containers with some lite services like teamspeak server, couple of bots, deluge and hestiacp, prometheus, k3s for testing and “vdi” in vm). Actually - i’m running docker - inside LXC containers. Not the prettiest way to do it, but it works fine

I’m using hestiacp to host some websites anyway, so i just added a new nginx template to create reverse proxy to lemmy+lemmy_ui containers

Myself i’m running a instance for two people in a pretty small lxc container on my home server- 1vCore, 512MB of ram and 8GB storage. Currently it utilize around 5% of CPU, ~250MB of ram (+260MB of swap), and ~2GB of storage (nearly 50/50 picts/postgres), in terms of network traffic i see average of 20kb/s, depends how many communities are you subscribed for.

My homeserver is running on i3-4150, 16GB ram and a couple of ssds, using Proxmox VE as hypervisor
