Take out the hard drive out of your laptop and put the drive for the server in it, install Debian using the built in monitor and keyboard of your laptop.

I use this all the time, also nice for text share.
And recently Llama3 and Mixtral!
I've a Dreame L10s Ultra flashed with it, very happy with my purchase. A bit scary to install everything but if you read the instructions before doing it you should be fine :)
RSS Guard seems to have support for Google Reader API, so FreshRSS is also supported. It's also a Qt application. You can also find other clients on the 3rd party clients page of FreshRSS
There are a lot of different methodes you could try. I think the easiest is to connect both systems with a (mesh)VPN like Wireguard, ZeroTier or Tailscale. Then you can simply copy stuff over using rsync -a (archive mode) with a cronjob or using special tools like Borg backup, kopia, etc
I don't think there is an app for something like that, but maybe you can try using Penpot in a browser?
I had the same issue with my Anonaddy alias, I just made an alias using my domain name and works fine now. It's unfortunate that so many project are on shithub.
You can use Universal Android Debloater. Most apps have a description of what it does and if it's safe to remove or not. Already debloated a few Samsung phones with it, works great :)
As far as I know you can't, but what I did was to connect the drive to a PC (Windows or Linux) and make a SMB share of it. There is an app on F-Droid that can connect to SMB shares.
