Writing

There are many more articles on my blog, but these are some of my favorites:

Code

I’m hrs on GitHub, where I’ve got a bunch of repos of varying quality. A few of the better ones are:

My dotfiles might be interesting if you’re maybe a little too into Emacs.
Some friends over at the Church Lab wanted a tool to search through their catalog of primers to find the ones that bind best to a given target region. I wrote PrimerFinder to help with that.
Blueprint is a simple Scheme implemented in Ruby. It includes a bunch of nifty features, including anonymous functions, lexical closures, variadic binding, and non-hygienic fexprs. It’s not the most performant language (it’s just a prototype), but it’s not too poorly written and it has a fairly complete test suite.
I don’t like leaving my editor to look up documentation, so I wrote engine-mode, an Emacs mode for dynamically generating URLs from search terms and opening them in a browser. It’s available on MELPA.
sensible-defaults.el is a collection of Emacs functions that knocks some of the rough edges off the default install. It adds syntax highlighting, relocates backup files, ensures that files end in newlines, and adds many other features. It’s a nice base configuration if you’re getting started.
While I was in grad school I wrote a simple little Python library over a weekend to help me solve a class project, put it on GitHub, and subsequently ignored it for years. The Internet found it, though, and now Python TF-IDF is, apparently, kinda popular. If you’re interested in a simple but inefficient implementation of the information retrieval algorithm term frequency-inverse document frequency, I guess it’s a thing to check out.

“Hypertext Art Installations”

Squawkbox.io: monetizing #parrots to empower consumers to interact with #brands. Disruptively. Coming soon to the Bay Area.
Plenty of services will allow you to take a long URL and shorten it, but no one’s tackled the problem of URL lengthening until now! Kilobytely is a free, stateless service that will transform a short, regular address into a grotesque and inscrutable leviathan of a URL.
Many couples adopt pet names for each other. A common pattern for pet names is “[food]-[body part].” Let Questionable Pet Names help you shower affection on your adorable widdle pudding-ears.
