dee.underscore.world is a static site, built with Lektor. Adjacent to it you can find fedi.underscore.world, which is running a Pleroma instance. Previously, this site could be found at deeunderscore.github.io.
I'm Dee, and I may or may not be an actual real human person. Sometimes I write code, sometimes I do other normal human things.
When I registered underscore.world, I wanted to have dee.underscore under an arbitrary top level domain. This arbitrary top level domain ended up being world, and it was only later that I found out there was an unfortunate name collision with someone else. Oops.
You can find me in a number of places on the Internet, generally under the nickname D_, DeeUnderscore, or some variation:
...and perhaps other places, where people with usernames similar to mine may or may not be me.
If you need to contact me, hopefully not with unsolicited advertising, see below:
