Side Projects

I write code in my spare time for the fun of it, so most of these projects are incomplete. Check out the source code, though; I have put a lot of time into these babies over the years.

underscore.as

Github link

A simple port of most of underscore.js 1.3. This was extremely handy back when ActionScript was relevant, and I am still proud of a few of the hacks I used to get the concepts working in AS3’s less flexible runtime.

Mazes

Github link

Lately I have been working through Mazes for Programmers, by Jamis Buck. The book is written in Ruby, but I have been reimplementing the algorithms in Clojure. In Ruby, you get to implement the algorithms more or less the same way you might do them in C++, but Clojure requires a very different style. This has been a pleasant challenge.

In particular, check out the maze generation and pathfinding algorithms in this folder. There is also a re-frame-based front end application which demonstrates some of the algorithms.

Alpha Counter

Github link

A life counter for the Yomi card game. Try it out at yomicounter.com: choose two characters, hit “Start Game”, then hit a few of the damage buttons and see what happens. Tap a life bar to change the target. The timing behind the combo damage accumulation and application is all done with core.async, Clojure’s equivalent of Go’s channel abstraction.

I wrote this because I didn’t like adding up damage mentally and tracking it on paper while playing the game. A great example of solving real-life problems with programming.

Raise Your Game

Github link

Although this project is intended to become a Youtube annotation site, I got deeply sidetracked into Clojure database and testing code. Check out the server-side code and its tests for a good example of hand-rolled Clojure account management.

If I had to do it over again, to be honest, I would just use Rails with some plugins. The client side was going to be the really interesting part of this project! However, I will say that there is something really satisfying about slowly building up a framework of well-tested code.

Wrongtangular!

Github link

At Paperless Post, at one point, we needed to populate the rectangular? attribute for thousands of paper graphics. We could not simply compare the width and height of the graphics, because transparent and nearly-transparent pixels greatly complicated the issue. Ultimately, we realized that a human would need to evaluate each image.

To evaluate each image at a glance, instead of laboriously clicking through our internal CMS, I created Wrongtangular!, a ClojureScript application which would display image after image to its user. With fingers on the home row, the user hits any right-side key to approve the image, and any left-side key to reject it. Kind of like Tinder, but for whether graphics are rectangular.

Later, I realized that it might be useful to have such an application for any arbitrary dataset and any boolean attribute. Hence Wrongtangulizer, a gem meant to be used in the Paperless Post Rails REPL to generate instances of Wrongtangular!.

Everything Else on Github

There are a lot of barely-started projects, sample code, and so on, but none of it is really worth reading.
