I use pfsense on my own metal. I can recommend it- never caused me any issues in the 4 years I've been using it, now. Even seamlessly updated major version twice.
I can only speak on behalf of Matrix Synapse, but enabling Federation and joining the matrix.org destroyed my server with a i5 6600k- it is very expensive to federate and the resource cost per user is very high if you're not sharing your instance with anyone.
Brian <- A name, but also a slur for people considered 'hillbilly'. Very frequently used against people who drive cheap tuner hatchbacks. Said cars can be referred to as Brian Cars.
Peter Jensen <- Also a name, but it's become notorious in Jutland because it feels like everyone is immediately related to someone with this exact first and last name.
OSM is very strict about verifiability of data. It is speculated that Overture is (because it also uses OSM data) meant to contain a lot more data that isn't as strictly verifiable. Think AI generated building footprints.
I would like a very small segment on IPv4, the implications of NAT and why NAT reflection should be turned on- why uPnP should never be turned on in residential networks and only if you know what you're doing in any other networks, and maybe how IPv6 solves some of these issues.
These are the issues I've struggled with. Even now I curse under my breath whenever I have to deal with NAT.
I just use a userchrome
