- Correlations and conclusions by Zed Shaw. Mr Shaw delivered a witty presentation on measuring performance of web apps. He compared web.py with Ruby on Rails in serving a “Hello world” application. To nobody’s surprise Python’s library won by an order of magnitude, confirming Zed’s proposition that “Rails sucks”. While one could argue whether it makes sense to compare the efficiency of a fork and knife in a spaghetti eating contest, the show was entertaining.
- TDD in Rails by Andrzej Krzywda. Andrzej is a Rails developer with a Java background. He shared his practical experience with a test driven development in different languages. While he advertised TDD as almost the only sane way to develop a software, I’m still a bit skeptical. I work mostly on the UI part of Ajax-heavy applications, and it’s hard for me to imagine even partial test coverage of complicated interactions. And what about automated testing of CSS layouts? I’m currently playing with Selenium, but my first impression is that it won’t be a silver bullet for front-end testing.
