Gatsby is great at turning everything into static HTML—which is exactly what you don’t want when some posts should be behind a password. In this post I walk through a practical, Firebase-backed pattern for selectively protecting MDX content in a Gatsby 5.

Let’s start with a major life update: I’m getting an MBA! I’ve been asked regularly why I left design and tech to spend a bunch of money on a degree that many in tech sneer at. I’ve thought a lot about this, and over the coming months I want to share my insights an observations from the experience. This essay is the first of what I hope is several to come.

Resetting a Tree's Visited State

June 06, 2016 | 6 minute read

If you've ever written an algorithm that involves traversing a tree or graph, you've dealt with the concept of marking a node as "visited". Often, this is act is taken care of of with a simple boolean flag in each node. This works great for single traversals of a tree; that is, you search a tree for something once, and then never look at the tree again. But what if you want to traverse the tree over and over again? Here I'll present a simple strategy for resetting the visited status to "unvisited" for all nodes in a tree in constant time.

GitHub Enterprise has been a godsend to developers working at companies that need to keep code on their own servers. GitHub was a distant dream at IBM before GitHub Enterprise, and now many of our teams use it. In fact, GitHub is so popular as a project management tool, many teams have done away with Jira and the like in favor of GitHub issues and ZenHub.

Using SocketIO with Python and Flask on Heroku

January 29, 2015 | 6 minute read

Sometimes all you want to do is put together small web app with a Python based server. Flask is the go-to choice and it couldn't be easier to use. Launching your app on Heroku with Flask is a well documented process. But things kind of hit a wall when you want to use SocketIO for websockets. Every tutorial online is basically a chat-app with an overly complicated process of integrating Redis, and at the end of the day, doesn't lay out the basics of bare-bones websocket integration. Often times, I simply need a few event handlers - not the full schebang. This tutorial explains how to set up an extremely simple Flask webapp including basic SocketIO event handlers, and launch it to Heroku.

Channel Coding for Mutation Resistance

January 04, 2015 | 3 minute read

What if historians today had access to detailed census data from hundreds or thousands of years ago? It's pretty obvious that our understanding of past cultures would be drastically different. However, what are we doing to prevent the same cycle hundreds of years from now? Where are we storing the massive reams of data that future societies would find invaluable?

How to Display Custom Images on a E-Ink Screen with Arduino

October 30, 2014 | 7 minute read

I recently got the RePaper E-Ink display to use with an Arduino Uno. The Arduino Uno isn't powerful enough to do more complex things like dynamically write content to the screen (such as text or shapes). What it can do very well is show images loaded into memory. However, I couldn't find any good resources for how to load custom images onto the Arduino — so I wrote on myself!
