Sites for Mozilla Input

written on Tuesday, 10th August, 2010

As a side project during my internship at Mozilla, I worked with Aakash from Mozilla QA to bring a new feature to the Mozilla Input website.

Oftentimes when users have trouble with a Firefox beta, there is not actually a bug in the beta, but a problem with a specific website (such as broken user agent detection). Even when a problem is related to Firefox, it can be very helpful for QA to see what sites trouble our users the most, and what issues the users face there.

Enter clustering…

To group sentiment by topic, my fellow metrics intern Andres and I made use of Dave Dash’s clustering algorithm, which uses techniques from the search engine world to group related input. That helps to get a quick impression on what’s going on when a site is causing trouble for many users. We also get a lot of positive feedback on sites where the user experience has improved for beta users compared to the release version.

…and Django of course!

It was very cool to do something with Django again. The webdev team is very knowledgeable in this area so I learned a lot working with Fred and Dave. There are some limitations (you still cannot prefetch related objects along the inverse edge of a one-to-many relationship, like with any sensible ORM), but other than that Django has become a pretty solid toolkit. Also I finally got started with Git, which is as of now my version control system of choice.

Hopefully my main project will allow me time to improve Input and the dashboard in the future, there’s a lot of cool stuff planned with it.
