Super epic update to my site after 2 months of inactivity- You can access a self-hosted, completely private search engine (powered by SearXNG) at search.bulletmaji.me! It's a bit slow and it's definitely not set up to handle large amounts of traffic, but it's a pretty neat thing to have. I'm going to try to use it as much as I can.
I was thinking of other things to host - a VPN, LLM, etc. But I'm not sure if they're very practical and it might just end up being a waste of resources. Maybe someday I'll try it out just to see how it goes though.
