Many of us have used the CFCONTENT tag that comes with ColdFusion to serve up files to browsers, but very few ColdFusion developers are aware that the CFCONTENT tag can be used in conjunction with the HTML tag to serve up graphics, such as JPEGs and GIFs. In this case, the why of doing this is perhaps just as interesting as the how. It turns out that using this technique is perfect for use with creating an advertising banner server, controlling access to graphic files, or - on the more sinister side - creating "Web bugs." If you don't recall, a Web bug is a graphic (usually an invisible 1 pixel shim) that is embedded in an HTML e-mail message or Word document that tips off its creator when and who is reading without readers even knowing their access was logged. If you've never used the CFCONTENT tag before, it's an excellent tool to become familiar with. In l... (more)

A Closer Look at CFScript

Allaire's esteemed guru Ben Forta introduced CFSCRIPT to CFDJ readers last year with his article "Stick to the Script" (CFDJ, Vol. 2, issue 7). Hopefully, some of you absorbed the words of wisdom from our evangelist and gave CFSCRIPT a shot, but I suspect for most of you the lesson fell to the wayside when it came time to hit the code again. I can't blame you. Paltry documentation by Allaire on CFSCRIPT coupled with most CF developers' inexperience in scripting languages makes it easy to ignore. Most ColdFusion developers don't have a scripting background. So why take up CFSCRIPT? It can't replace conventional CF tag structure. Although a modest performance gain can be seen in some circumstances, its exclusion of CF tags significantly limits its potential functionality. What does it offer most developers who are not seasoned scripters? I believe it can make three co... (more)

CommonSpot Content Server 3.0 from PaperThin

Currently there are more than 200 commercially available content management systems (CMSs). Each has strengths and weaknesses relative to the others...belying their underlying middleware platform and customer history. While not all are ColdFusion based, I believe that the CommonSpot Content Server 3.0 (the 2001 CFDJ Readers' Choice winner) from PaperThin, Inc., sets a new standard for flexibility and performance across all middle-tier systems. Comparing Apples to Apples Believe it or not, there's quite a bit of controversy within the CMS industry about what functionality a "Web content management" system should bring to the table. After evaluating many CMS applications, however, I've found that most vendors offer the following core set of features: Nontechnical content contributors may modify the contents of their Web sites anytime, anywhere, through their Web browse...

Best Practices in ColdFusion Development

In recent years we've witnessed a trend in which organizations gather, codify, evaluate, and disseminate seemingly endless lists of "Best Practices" - guidelines that help promote the success of their business, the consistency of their actions and, presumably, the general cheerfulness of their employees. Best Practices are cherished by neophytes and mentors alike for many reasons. For beginners (or those toiling fiendishly into the night, alone in their basements, who can't help but cackle, "It's alive!" every time their application runs without crashing), Best Practices offer a coherent and consistent mode of communication with fellow coders who might inherit their work. They also offer guidelines that hasten the debugging process, and they create a compendium of development tips and tricks that can be time consuming to find on your own. For more seasoned develope...

Propel Your ColdFusion Projects with Application Frameworks

What is an application framework? This article defines the term and compares three current application frameworks or methodologies. I'll also explain how they're used to implement "foundational" functionality, which can be reused in other applications with little or no programmer involvement. What Is an Application Framework? I've often used the metaphor of building a house when discussing the Web application development process with my clients. When building a house, different subcontractors come in to complete separate but equally important building tasks. An application framework is like having the lot cleared, the slab poured, and the frame raised. I call this part the foundation. The soundness of the foundation is critical. If it's not well constructed, you might be better off tearing down the house and starting from scratch rather than adding that second story.... (more)

Using the CASE Expression in SQL Queries

The DBMS (database management system) is often faster at performing calculations like summing up or averaging the values in a column of numbers than, for instance, the application server. However, there are many cases in which performing the same calculation on all of the data in a column will not provide the correct result. This article will show you how to use the CASE expression in SQL queries to more flexibly perform aggregate calculations and set values based on a logical statement. An example of the need to apply the CASE expression in an aggregate function is an online shopping cart with several item-specific options that, depending on the options chosen, change the way an item's price is added to the cart and, therefore, the final total price of the order. I will discuss a shopping cart for an online store that requires variable pricing within four option ... (more)

Adobe Reports Third Quarter Fiscal 2012 Financial Results

Adobe Systems Incorporated has reported financial results for its third quarter of fiscal year 2012 ended Aug. 31, 2012. Adobe achieved revenue in Q3 FY2012 of $1.081 billion, within its targeted range of $1.075 billion to $1.125 billion. During the quarter, the Company drove faster adoption of Creative Cloud subscriptions than originally projected. As Adobe customers migrate from a legacy Creative Suite perpetual licensing model to new Creative Cloud subscriptions, revenue is recognized over time as opposed to at the time of purchase. This overachievement in subscriptions during the third quarter effectively transitioned approximately $29 million more perpetual revenue than expected to Creative Cloud. In addition, the effect of currency impacted Q3 revenue negatively by approximately $9 million. Adjusting for these amounts in Adobe’s reported results would have en... (more)

Where Are RIA Technologies Headed in 2008?

I am always being told off by i-technologists for quoting Picasso as having said that computers are useless. But I still love his reasoning? "Because they can only give you answers." Picasso, like AJAXWorld Magazine, liked questions. So we thought we would share with you what some of the world's leading rich Internet application pioneers are thinking may be the next questions that we need to see answered. From that readers can themselves infer where AJAX is headed. What are the top questions to ask next about AJAX? Eric Miraglia of Yahoo! 1.  (From March'08) How do I calculate the ROI of building my RIA on the iPhone SDK vs using AJAX? 2.  How do I assess the performance of my app and decide what to do next to make it faster?  3.  When it comes to accessibility, how do I know what's required of me for my rich web apps?  Beyond what's required, what makes good business se...

The Next Programming Models, RIAs and Composite Applications

I’ve been around software for 20 years now. Looking back, I have mixed feelings about the progress we’ve made. The end results have been amazing but the process of building software hasn’t fundamentally changed since the 80s. In fact, I see us make some of the same mistakes over and over again. One of the common anti-patterns is over-relying on tools and frameworks instead of inventing new programming models. Layers of abstraction are fundamental to software. Some layers are defined through programming models, e.g., machine language, assembly language, 3GLs, JSP. Others are defined through a combination of tools and frameworks, e.g., MFC and Visual Studio on top of C++. There is a limit to how high we can raise a level of abstraction through tools and frameworks alone. At some point, a new programming model is the best way forward. Here are some examples: CASE tools ... (more)

The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, compared the Jevons Paradox to modern-day enterprise IT, examin...
