Online chat solutions have been very popular long before AJAX was born. There are numerous reasons for this popularity, and you’re probably familiar with them if you’ve ever used an Internet Relay Chat (IRC) client, or an Instant Messenger (IM) program, or a Java chat applet. AJAX has pushed online chat solutions forward by making it easy to implement features that are causing trouble or are harder to implement with other technologies. First of all, an AJAX chat application inherits all the typical AJAX benefits, such as integration with existing browser features, and (if written well) cross-platform compatibility.

As part of a large undergraduate history course he teaches about World War II, Dr. Martinez developed a mapping mashup that he introduces to the 150 students at the beginning of the semester. The mashup, which works with Google maps, represents major events leading up to and during the war. Fundamentally, it’s a map, he explains, showing them on a projection screen that it works very much like the online mapping tools students regularly use. The map covers virtually the entire globe, and users can move around the world, zooming in and out, showing the area of search as a map, satellite images, or satellite images with maps, dates, and events superimposed.

What Are Scripting Languages?
Languages like C and C++ allow a programmer to write code at a very detailed level which has good execution speed (especially in the case of C). But in most applications, execution speed is not important, and in many cases one would prefer to write at a higher level. For example, for text-manipulation applications, the basic unit in C/C++ is a character, while for languages like Perl and Python the basic units are lines of text and words within lines. One can work with lines and words in C/C++, but one must go to greater effort to accomplish the same thing.

How does Google decide which web sites are important? It uses an ingenious algorithm that exploits the structure of the web and is resistant to hacking. Here, we describe this PageRank algorithm, illustrate it by example, and show how it can be interpreted as a Jacobi iteration and a teleporting random walk. We also ask the algorithm to rank the undergraduate mathematics classes offered at the University of Strathclyde. PageRank draws upon ideas from linear algebra, graph theory and stochastic processes, and it throws up research-level challenges in scientific computing. It thus forms an exciting and modern application area that could brighten up many a mathematics class syllabus.

Google Analytics - free online web analytics | The 3-year-old web application, created by Google after acquiring Urchin Software, that allows businesses to make better decisions with respect to their web applications.
1. Start with the correct user account
Since Google Analytics (GA) is a free tool that processes incoming tracking data on-the-fly, but there is no way to bulk transfer data between accounts. Setting up a long-term email address for your account is crucial, especially if you don’t want to keep multiple sets of data around in the future. Create a generic account based on your domain called google@domain.com - then simply use your ISP to forward that address to the appropriate one.
