A web service that serves IP address geolocations in JSON format.
Instead of relying on a local database it collects data from a (configurable) series of 3rd party providers, converting the results to a commom format. It supports provider fallbacks and caching.

A web service that fetches thumbnails with title from URLs.
Originally planned to use it in a chat service to prevent the tracking of users by letting them download images directly.

A http server that serves random (version4) UUIDs.
It uses my hybrid pseudo- and true random generator library which periodically takes seeds from random.org and uses them to generate pseudo-random UUIDs fast.

Riddle Solver is a terminal app designed to solve Einstein's 5 house riddle. I think I came across this kind of riddle playing Dishonored2 first as a
third option to get inside a locked place. It was written by a fictional genius game character named Kirin Jindosh and it's clearly based on Einstein's
five house riddle. It took me (sadly) at least 30 minutes to solve on paper, but it earned me an achievement.
Fast forward 3 years, I had the random idea of implementing this riddle solver, which seemed like a simple way to sharpen my Golang skills. I was wrong. Coming up with the UI design and the solver algorithm caused me quite a few sleepness nights, but I'm really proud of the result.
