Language Wars - PHP, Python, Ruby Want to start an argument? Simply say any one of the three languages, Python, Ruby, PHP, is the best. Programmers tend to be very fixed in their language preferences and very ready to recommend their favorite to you. I wouldn't really say it was war, but these three languages present a real dilemma when you are trying to choose. The main similarity from a technical point of view is that they are all dynamic object oriented languages. So why invent a new language? The answer is basically because people found that the existing languages didn't do what they want. So why three languages? The truth is, and here I am inciting wrath from each of the three camps. there isn't that much difference. They are all dynamic, object-oriented languages - even if PHP had to evolve to become so. PHP is possibly the outlier in that it really isn't an elegant language. Both Python and Ruby were better designed from the outset than PHP, but they don't occupy the position of the essential server side language.

Ask for a User Name After The User Has Signed Up Sign-up forms typically ask users to create a name that is unique to the website. Require Users to Type Their Password Only Once Many sign-up forms ask users to type their password in two different fields. In reality, though, this allows for greater error, because it forces users to type more. A more efficient approach would be to ask users to type their password in once, but then include a box they can check to unmask the password, so that they can check it. jQuery Plug-In for Masking Passwords1 Auto-Fill City and State Fields Based on User’s ZIP Code If you require the user’s home address, then consider auto-filling the city and state fields based on the ZIP code.
