This web page is hosted using Keybase Sites.
It started off as a test, to see if https://jms1.keybase.pub/ worked the way I thought it did. (At the time, it did.) Then, in 2023-02, Zoom (the owners of Keybase) announced that they would be shutting down the keybase.pub domain, but the Keybase Sites service would continue to work.
If you're seeing this page as jms1.keybase.pub or keybase.pub/jms1/, you're seeing it through the keybase.pub service (which has shut down, so you're not seeing it through that hostname).
If you're seeing this page as jms1.pub or www.jms1.pub, you're seeing it through Keybase Sites, which will hopefully not be shutting down.
Regardless of where or how you're seeing it ... the file you're seeing is just a file called index.html in the /keybase/public/jms1/ directory. If you're already using Keybase, feel free to have a look around in that directory. It has some files that I personally find useful and/or funny, you may also enjoy them.
And if you're not already using Keybase, you can download the client and join right now.
Keybase Sites offers a way to host web sites whose content is stored in Keybase private or team directories, using URLs which are in other domains (such as domains you may own already). It works by using the Keybase user "kbpbot" to retrive the files as they are requested.
This page explains how to use it, in more detail.
jms1.pub.asc is the PGP key I'm currently using for anything not related to $DAYJOB.
