Are You Taking Things Too Far?

Sometimes as developers it can be a little too easy to lose sight of
the big picture sometimes, we can get carried away with following the
conventional wisdom without thinking about why that wisdom became
conventional. Several great ideas and techniques can become huge
time-sinks or distractions if we’re not careful.

Just because something is a good idea in moderation, doesn’t mean it’s
a good idea when overused. In this talk I’ll question some of the
orthodoxy which has built up in the rails community. Topics will

  • Building DSLs
  • Focusing on Beautiful code
  • Testing, Specs and Mocks
  • Being RESTful
  • Avoiding Premature Optimisation

Hopefully by moderating our excesses in some of these areas, we can
free up some time to improve our applications, or step back and take
some time off to relax.

Koz brings some common sense to things, and it was interesting to see things that were highly controversial last year be accepted this year.

Koz carried it off well, but the strength of his speaking ability was important to this. The content was probably about what I expected, but perhaps a few more examples (or, I guess, areas) would have made it a bit better.
