compile my own custom android

great, perfect imo

use a cheap vlan switch to make an actual vlan DMZ with the services’ router

use non-root containers everywhere. segment services in different containers

is old fashioned non-hyphenated?

like red tree

use nixos! you won’t regret it

have a rest

people with their one liners like “i’m tired boss” need to do one

i just transitioned from a dedicated pfsense machine to openwrt LXC container in proxmox machine

the idea is to have 2 or more openwrt instances in different proxmox machines for some HA routing to my self hosted subnet(s)

going well so far and i think i know a lot more about routing (ha). openwrt is pretty great though.

ps. i think i’m having issues with udp port forwarding but not sure

do you prefer the more current term marxist-lenninist like lee oswald?

true though, isn’t it, not being relevant since roughly… 89?

i agree, commies trying to claim FOSS is really a stretch, they are desperate to pretend to be relevant

i have found this reference very useful https://mynixos.com/options/

yeah proxmox is not necessary unless you need lots of separate instances to play around with

this is my container config for element/matrix podman containers do not run as root so you have to get the file privileges right on the volumes mapped into the containers. i used top to find out what user the services were running as. you can see there are some settings there where you can change the user if you are having permissions problems

you only need to reboot Nix when something low level has changed. i honestly don’t know where that line is drawn so i reboot quite a lot when i’m setting up a Nix server and then hardly reboot it at all from then on even with auto-updates running oh and if i make small changes to the services i just run sudo nixos-rebuild switch and don’t reboot

i guess you were able to install the os ok? are you using proxmox or regular servers?

i can post an example configuration.nix for the proxy and container servers that might help. i have to admit debugging issues with configurations can be very tricky.

in terms of security i was always worried about getting hacked. the only protection for that was to make regular backups of data and config so i can restore services, and to create a dmz behind my isp router with a vlan switch and a small router just for my services to protect the rest of my home network

nixos with nginx services does all proxying and ssl stuff, fail2ban is there as well

Leptos is very React-like but it’s Rust so it will be Rusty sometimes. you mentioned you’ve done the back end in Rust anyway.

with LLMs do you mean code suggestions like code-pilot or actually integrating with an LLM api?

do the front end in Leptos and host it on ForgeJo

no matrix instances!!??
