I’ve had a sudden spark of interest in chess as of late 2022 and decided to build my own web chess app with focus on simplicity and ease of use. Also I didn’t want to waste time convincing friends to register to [insert your favorite chess platform here]. With RazChess you just visit the website, copy the link of the session and pass it to the person you want to play with.
As weeks passed I kept adding new features like chess puzzles (mate in two steps), Fischer random (chess960) game, included chess openings encyclopedia, custom games and the ability to download your matches as GIFs. There is also Redis support to restore active games after a restart.Try it here:

Riddle Solver is a terminal app designed to solve Einstein’s 5 house riddle (also called zebra puzzles in general). 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.Riddles:
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.Try it here:

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.Try it here:
