One of the topics that comes up most often when talking with CF developers about ColdFusion is performance. Recently, I assisted two CF developer friends with some site speed problems that they were having. One of them is a beginner, a developer who couldn't understand why his site was...
For the past couple of issues we have been getting to know how other languages use object-oriented design patterns and how those patterns can be implemented in ColdFusion MX. We jumped right into the Template Method and Iterator patterns and this month we will explore the Strategy patt...
Every developer will at some point have to integrate his or her work with a legacy system running on a mainframe platform. These projects tend to be both painful and challenging due in no small part to the limited information- sharing capabilities of outdated, albeit stable, systems. X...
It's a week before your new ColdFusion application is set to go live, and your boss saunters in and asks, 'If the client's browser is closed, and they aren't in their e-mail client, how will we notify them of new changes?' Of course, this should never happen in a well-managed project, ...
I recently reviewed Macromedia's new 'Developing Rich Internet Applications' (CFDJ, Vol. 5, issue 2) course to make developers interested in adding Flash to their arsenal aware of this terrific new offering from Macromedia Training.
Using JavaScript to perform client-side input validation can be simple. However, the task can become more complicated when the set of inputs changes or increases in number, the rules change, or the validation depends on other inputs. This article will show how to create a system to dyn...
Is your CFMX server running with the latest set of fixes? Macromedia now uses 'Updaters' as a means to apply patches and extensions. There have been three so far. Are you running the latest, or any at all? How would you know? And why should you bother?

I receive lots of e-mail from lots of ColdFusion developers, and make every effort to respond to each and every one of them. Knowing the problems that ColdFusion developers are attempting to solve helps me know what topics to write and speak about. Indeed, the inspiration for most of m...
It seems that lately, you can't pick up a book or magazine without hearing about design patterns. If you're new to the idea of design patterns, they're simply time-tested solutions to common problems. Design patterns began with the work of Christopher Alexander, a PhD in architecture (...
In March, Macromedia created quite a stir in the community by releasing a completely new version of their Web site (www.macromedia.com). This beta version of the site reflected the Macromedia vision of the way Flash can be used with ColdFusion (or any other application server) to deliv...
When SYS-CON Media's sister company, SYS-CON Events, began preparing last year for this spring's 'Web Services Edge' Conference & Expo, one consideration was paramount: every effort in the nine-month preparation cycle should be geared toward making it indisputably the world's largest i...
