Article is spot on for all sorts of reasons. Never mind people typing in domain literals like me@[1.2.3.4]. Internationalised Domain Names are going to REALLY screw over some regexes, given how poorly understood Unicode is. Does Ruby even have Unicode regex support yet? I don't program in it so I'm unfamiliar with the state of the art. On my pet topic of Unicode, I especially enjoy the use of hidden form fields to reverse-engineer the character encoding certain browsers ACTUALLY send on submission rather that what your code hoped for... Good luck convincing management to Do The Right Thing here.
