This is RobJH.com. My personal website. It's still very much a work-in-progress and so some features are still missing. That said, I don't have a goal in mind, and I only work on this sporadically.
You can navigate the site by using the shell in the header, using commands commonly found on POSIX compliant operating systems.
To see a roster of the currently implemented commands, type: ls /bin; ls /usr/bin;
Recent work as been focused on rewriting the old propriatry backend to a set of static files and a python generator.
The generator and all the raw files get pushed to github every night, if the server's working properly, and can be found at https://github.com/robjh/website.
Theres a page for that; yourdata.html
I've not tried to perfectly replicate the experience of using a GNU/Linux computer in a browser. If that's what you came here expecting, you should check out this fine project: https://bellard.org/jslinux/.
