  2. Where I went in 2013

    January 05, 2014

    2013 was my first full year on Foursquare, so I thought it would be interesting to take a look at my data. Foursquare itself doesn't have great visualization or analysis tools built in, but there are a few third party services that do that. The main one I use ...

  6. Switching from Wordpress to Pelican

    November 04, 2013

    I was looking at my server memory the other day, and saw that mysql and apache were taking up way too much memory. I read about static site generators before, so I decided to try them out. The main ones were Jekyll (and Octopress), Hyde, and Pelican. I went with ...

    For about a month now, I've been working on a backend service in Scala. This service is simply a REST API: It fetches a string from redis, parses it as JSON, extracts some keys, serializes it as JSON, and returns it. Pretty simple stuff. I've also just finished ...
