• Quizmaker - Steven E. Ellis, Ph.D. sent in this awesome hack. The script prompts the user through a series of questions and menu options to generate a quiz.

Multiple choice, matching, true/false, and fill-in question formats are supported. Finally, the Quizmaker script uses all the inputted information to create a quiz. The quiz is created in a new directory (by default as a subdirectory of c:/temp) that contains all the files need to administer the quiz. All the user needs to do to activate the quiz is copy the directory to a PERL-friendly http server and set up links to the quiz questions and results forms.

• Credit Card Validation - Doug Miles sent in this extremely useful credit card validation library. The purpose of the library is twofold. First, it catches credit card information typographical errors. Second, it prevents someone from just "making up" credit card information (i.e. credit card number). However, just because a credit card successfully passes all the checks in this routine, (obviously) does NOT mean that there are funds available on the card, NOR does it mean that the person who is submitting the card information is the actual owner of the card. This routine simply verifies that: 1. the card is a valid type (VISA, MASTERCARD, AMERICAN EXPRESS, DISCOVER), 2. the number is a possible valid credit card number, and 3. the card has not expired.
