Basically it is open unix server (Pubnix). You can do all things u can do in unix but without root privileges but nix solve that issue too.
Idea is to create a community around unix. U have Mail, irc, matrix and a text forum to talk to others on server. U also have a static site (also gopher and Gemini too.)
Basically ssh code deploy talk compile and show ppl what u did.
I use it for good community (as PSF is mostly Indians), Some Static site, Run AI (Ollama), Keep ever running telegram,matrix,xmpp and irc. Compile programs for email they give u username@domain.tld (mostly) and other services they provide (nextcloud,matrix etc).
Basically your home on internet.
Talking about SDF they are like corporate version of pubnix while most servers are community ran. Will never suggest to join SDF . They actually clear your account data (your home directory) every 666 days and to stop it u need to pay (just being active is not enough) If u ever want to join some pubnix. Join psf.lt (Best) or envs.net (No nix but great services) vern.cc (everything is great just high ping I guess). Also never talk about vern on PSF as admin of PSF is exadmin of vern and he quited that server after some thing happened bwn arya and cobra (the new admin of vern)
Bye… Let me clear my jee exam. (Just 6 months left man 😅)
In cromite you can set to open a website in desktop mode by default.
