I meant to post this some time ago and recently found it in my “drafts” folder.
While working on my current project, everypodcast, I needed to implement an RSS feed parser, mostly for iTunes RSS feeds. Initially I went with the builtin
RSS package from the standard library. When reading a lot of large XML feeds, I noticed that parsing those feeds takes anywhere from 0.5 to over 30 seconds. At the same time the process was using a 100% CPU.
After some searching I found Feedjira. With this, it now takes on average 0.5 seconds and at most 1.5 seconds to parse even the longest feeds. Furthermore it has dedicated support for different types of RSS feeds, I highly recommend it.
I wanted to test some part of my application that performs HTTP requests against a different website. Now, for testing, I didn’t want to perform actual outside HTTP calls because they tend to become flaky if the internnet becomes unstable or when the remote resource is not available. Another reason, why I didn’t want to use the rails server and their static files, is that I didn’t want to serve those files in production. So I decided to write my own static file server.
Really clever from the New York Times. You can create your own here.
As the final step in this very small series I tried improving the SEO (search engine optimization) score for my start page. I started out with a good score of 92. As usual, my goal was 100.
