Rails: the new disruptive technology
Brian McCallister has written an article describing why Ruby is causing such a stir in the Java community. His thesis is that Rails is the leading edge of the disruptive technologies available today (LAMP) and as such is the technology that is biting into and going the furthest into the lower end of the Java market. It is an interesting idea.
It is amazing how much of a commotion one little framework can cause.
