An Architect’s View: “Don’t get me wrong: competition is a very good thing but I have a background in international standards where compatibility is king. An alternative isn’t ‘free’ if it isn’t compatible…”
(Via cornfield.org.) – Interesting discussion going on over on corfield.org about BlueDragon (a product which lets you run ColdFusion code without having ColdFusion app server from Macromedia). They have to keep compatible with Macromedia so they’re constantly catching up. None of these types of problems in the PHP world (yet).
