Recently discovered Night Runners (free demo on steam if you are interested). The soundtrack is a blast and it is very fun. Very hyped for the official release :)

Discovering Octopath traveller II. Not a big fan for now, It’s beautiful but I’m a bit disappointed by the story. Hope it gets better 🤞

I’m not sure about Plex, it is not really 100% self hosting, because authentication come from their server. You should try and see if it works. But their is no reason it should not. It’s just an addition in your caddyfile :

plex.mydomain.com {
    reverse_proxy 192.168.0.123:32400 (your address:port)
}

However, i can assure you it works with Jellyfin.

One think you need to check before is your upload speed. Without a good one, it will essentially be useless outside of your home.
As for the computer, definitely buy something that can do virtualization, I’ve heard that some motherboard can’t (never seen one, maybe it’s an old thing).
And last, even an old computer can be good for self-hosting, except the plex / jellyfin video, almost everything is static webpages with databases. You can upgrade later just by changing the components, add more storage… You can even copy your entire system to a new computer if you change entirely.

Is it a good idea to host so many services, both publically-accessible websites as well as services only available on my home network, from the same machine?

You can use Caddy’s reverse proxy to have easy https + not opening ports from your router and have something like plex.mydomain.com / mastodon.mydomain.com. And you’ll have no trouble hosting differents services from the same machines. I believe it is not a problem to have multiples services on the same computer.

What are the security considerations when self-hosting?

I’m not an expert, but never use the default password when installing a service. And keep your stuffs up to date. https is important too, but is often automatic when using a reverse proxy.

If you have more question no problems :)

I’ve accepted the fact that sometimes It is ok to let a game unfinished. If I had enough with a game in my backlog and I don’t want to play it anymore, I stop and play a new one, the game is « done ». If I finish then the game was a really good one !
Careful with forcing yourself to play !

Wait, they’re still printing movies O_o
I thought it was only stored on computer nowadays. This is sick !

If you’re into self hosting, this repository is simple to install and use for sharing images.
