The Ruby on Rails story is usually presented to the new developer as a wonderful break from tradition that makes a developer’s life so much better than the frameworks of the past. The clattering of skeletons in the closet you’re hearing? Well, that’s because it makes the sysadmin’s life much worse than PHP or Java. That just improved on Friday, with the release of mod_rails.

Technical architecture (the act of researching and specifying a set of technologies to address a particular need) is a form of investing. Sadly, like stock market investors, many technical architects are blinded by hype, hero worship, tribalism, and short-sightedness, and make poor decisions as a result. A comparison between current web application development issues and the stock market may help you to avoid these tendencies in yourself or your team.
