It sounds like you and OP have the right idea. But please don't forget that ~8% of men and ~0.6% of women are colour blind, and there is more than one type of colour loss. Always distinguish unique colours with a unique shape (or pattern). Just like traffic signs.

Here's the proper way to do email validation:

Cal Henderson's routine is the best RFC compliant regex I have ever found to verify an email address:

I believe the engineer in question is Cal Henderson. Last I heard, he'd just built this to help him get from his new SF home to his desk at Yahoo! HQ.

He spends a fair chunk of time talking about how flickr was built, the notes of which are really interesting for anyone concerned about scaling out a web app.

Grim on iamcal recently imitated Mr. T to gain the confidence of a Liberian scamster, plus his exceptionally dodgy "lawyer" friend. Worth a look for shits and giggles.

Well, you could always submit some photos to Am I Evil Or Not? Meanwhile, here is a handy reference chart:

• Apple divisions:
• Hardware: Not Evil. Sexy, generally support standards, but don't allow clones.
• MacOS: Mostly Not Evil. Open source kernel, proprietary GUI, sometimes antagonistic to developers.
• Software: Mostly Not Evil. Free stuff often made at the expense of loyal Mac developers (SoundJam, Watson, etc), but lots of open source as well.
• Legal: Very Evil. Send cease&desist letters at the drop of a jellybean, and threaten the DMCA.
• Steve Jobs: Chaotic Neutral. As an insane liberal genius, he disdains your quaint notions of human ethics.

• Microsoft divisions:
• Windows: Evil. Monopoly abuse, swiss cheese security, embrace/extend/extinguish.
• Office: Necessary Evil. Would be much less evil as an independent company.
• Explorer: Mostly Evil. Proprietary muscle to push Windows monopoly, but support web standards.
• Legal: Evil. Submits fake evidence, colludes with DoJ.
• Games: Partly Evil. Tool to maintain Windows monopoly, but decent products.
• XBox: Partly Evil. Burning MS slush fund in attempt to capture a console monopoly, but it's a decent rig.
• Hardware: Not Evil. MS Mouse & Keyboard are nice.
• MSN: Mostly Evil. Plays abusive games to screw up MS competitors.
• Hotmail: Partly Evil. Spies on your clicks in email links, but supports anti-spam filtering
• Bill Gates: Lawful Evil. Very Exactly Lawful Evil.

• IBM:
• Not Evil. Formerly Big Brother, now #1 Linux advocate and possible savior of Apple.

• Red Hat:
• Not Evil. Would love to kill off all the other Linux distributors, but you can't really hate anyone who gives away their main product.
