My new app (still in internal alpha),, is intended to be a place where people can play real-time word games online. Especially during this pandemic, it appears in-person games of any time have completely ceased, and we board gamers need something to keep us sane. Besides joining like 6 different games in the upcoming Mind Sports Olympiad, the main way I’ve tried to scratch this itch is to gather a team to code up a way to keep crossword board games alive.

I first saw lichess like 5 years ago and thought it was the most amazing thing ever…

Around April of 2017 I wrote this article about moving my side project to a single-node Kubernetes cluster:

As of today, the infrastructure is still running strong, although I’ve run into a few issues I will talk about later in this article. I initially set up my node as a $10/month node but it was barely not powerful enough. Since then, Digital Ocean seems to have roughly doubled the CPU/memory for each of its instances, so $10 might work out. The Kubernetes docs mention that your nodes should have at least 2 GB of RAM, which means a decent…

This title may already be ringing some faint alarm bells; why move a small side project to use Kubernetes? And was it worth it?

I run a small study site for tournament Scrabble players, available at (Please excuse the lack of a nice landing page). It consists of a Django app, with PostgreSQL, and a small Go-based microservice that generates some complex word challenges on demand. The reason that service uses Go instead of Python had mainly to do with performance, but partially I was also experimenting with Go at the time. The site also uses SQLite to store…

The article here sums up pretty well the debacle that North American tournament Scrabble players have been faced with since the introduction of the new Tournament Word List in April of 2015:

Basically, Hasbro or Merriam-Webster or both decided to take the volunteer work various Scrabble players did in putting together a new word list, slapped a copyright on it, and made it impossible for players to obtain a digital version of the word list. This rendered various study tools such as Quackle, the best Scrabble AI, close to useless. I’ve heard a few players argue: who cares if Quackle…
