Keeping up with the latest Web technologies is tough nowadays. Every week it seems new sites are launched that push the envelope further and further in terms of what can be accomplished using just a Web browser. The rise of AJAX over the past several months has taken over the development world and breathed new life into the Web. Although these techniques have been possible for many years now, the maturity of Web standards like XHTML and CSS now make it a viable alternative that will be viewable by all but the oldest browsers. It's also been possible to accomplish many of the same things using Flex or Flash, but the development cycle with those applications is typically more involved and the overhead often not justified. We're going to harness the power of the Scipt.aculo... (more)

An In-Depth Look at Mapping APIs

Back in the November 2005 issue of CFDJ, we looked at how to create a live map of your Web site visitors using Google Maps and other freely available services. Now that Yahoo! and Microsoft have joined the fray and released their own mapping APIs, we'll revisit our example while learning about each implementation along the way. All of these APIs are extremely powerful, but each has its ... (more)

Tracking Errors: How Good Is Your Code?

Nobody likes errors, but the bottom line is, they're a fact of programming life. The better you are at pinpointing them, the better your code will get. Unfortunately, ColdFusion has never provided very good functionality for tracking the errors that occur within your production applications. I mean how many of you actually look through your application.log? For those of us with busy serv... (more)

Defeating DoS Attacks

A denial-of-service (DoS) attack is an attempt by a single person or a group of people to disrupt an online service. It is designed to bring the server and network to its knees by flooding it with useless traffic. A DoS attack is the most common type of Internet attack and can be launched against your site at any time with relative ease. This can affect you by eating up your bandwidth an... (more)

Visualize Your Visitors with Google Maps

The availability of the Google Maps API has opened up a slew of new development possibilities and spawned a bunch of web sites that rely on this data to function. Example applications include jogging trackers, subway map overlays, and other cool ideas all made possibly by the public availability of the mapping API. Geolocating by IP Address Geolocation refers to the ability to locate a us... (more)
