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.

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)
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)
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)
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.
