A web page is interactive when it prompts a response from the user.
Immediacy is the key to interactivity: If you click on a button that says “chat,” then that experience would be considered “more interactive” if you are immediately able to chat with someone online. The experience would be “less interactive” if the response was an email address for a mailing list on which you are allowed to discuss a particular issue. Interactive is really just another code word for describing how graphical elements in web pages work together with the software behind them.
A monospace font, such as Courier, is one in which every character takes up the same amount of horizontal space.
Thus a thin “i” in a monospace font would have the same width, or pitch, as a fat “w.” A font in which an “i” is relatively thinner than a “w” would be a proportional pitch font, such as Times. Pitch is usually expressed as the number of characters printed per inch. Common pitch values are 10 and 12. Because monospace fonts have constant widths, they are often used to align tabular data into columns.
Dynamic HTML (dHTML) is a markup language designed to heighten the interactive browsing experience.
Because dHTML can utilize each action of the user (a mouseclick, a rollover, a keystroke), it provides a rich and transparent way to process this data.
Practical extraction and reporting language, or Perl, is a scripting language first created by Larry Wall to be used as duct tape for programming with the Unix operating system. Due to its immense power for handling piles of text and, consequently, as a common gateway interface (CGI) scripting language, Perl became very popular among server-side scripters. Perl has a large community of contributing programmers and, what’s more, costs nothing and is free to redistribute. These circumstances have helped Perl evolve from a scripting language used to generate server stats into a language many use for database administration. All along Perl has maintained its zaniness. Most Perl documentation reads as though written by early vaudeville comedians.
The release candidate stage is the stage right between beta and final release, and it’s the last chance for developers to test their code against the browser before it’s push out into the world full-force. It’s also the stage at which add-on developers can update their third-party extensions without worrying about further code changes.
