Either self-hosted or cloud, I assume many of you keep a server around for personal things. And I’m curious about the cool stuff you’ve got running on your personal servers.
What services do you host? Any unique stuff? Do you interact with it through ssh, termux, web server?
On my Raspberry Pi 4 4gb with encrypted sd is:
Pi is overkill for this kind of job. Load average is only 0.7% and ram usage is only 400M
What server are you running for this?

can you tell us how you got this running with an encrypted SD card?
That was really hard to do. I created a note for myself and I will also publish it on my website. You can also decrypt the sd using fido2 hardware key (I have a nitrokey). If you don’t need that just skip steps that are for fido2.
The note:
Download the image.
Format SD card to new DOS table:
