value Over the weekend, I went to see The Best Exotic Marigold Hotel. The story line took a little while to pick up momentum; but, once it sucked me in, it ended up being a truly delightful movie. Definitely one that I would recommend. While watching it, however, I started to think about the relationship between the body and the soul and how the reality of a movie is often removed from the reality of every day life. ...&#160;<a href="http://www.bennadel.com/blog/2378-Movies-As-A-Religious-Experience.htm">Read More</a>&#160;&#187;

value For the last couple of months, I've been thinking a lot about my level of programming and my architectural understanding. Currently, I feel like I know enough to get most things "done." But, with the increasing complexity of my applications, especially those that require robust, modular client-side JavaScript, I'm filled with anxiety that I won't be able to create code that is easily maintainable and augmentable. As such, I've been putting a lot of time into reading up on Object-Oriented best ...&#160;<a href="http://www.bennadel.com/blog/2377-Creating-Service-Objects-And-Value-Objects-In-A-Dependency-Injection-DI-Framework.htm">Read More</a>&#160;&#187;

Cropping wasn't really what he wanted; but, since ColdFusion's list of native image functions doesn't have some advanced functionality, "cropping" is the terminology we're most comfortable with. What I believe Evagoras really wanted was a way to "punch" part of the image out.

value As of ColdFusion 10, the "Query" attribute of the CFLoop tag can now be dynamic. That is, it can refer to a dynamic expression rather than a static name (string). At first, this seems like a really cool idea - one that you've probably even wanted over the years; but, don't do it. Using a dynamic query value forces you to, as far as I can tell, use unscoped query column values. Granted, this is just my personal opinion but, I feel very strongly that this is a bad idea.

value Yesterday, I was working on merging some CSS (Cascading Style Sheets) rules into an HTML document, converting style sheets into inline "style" attributes. My default approach was to just inject the CSS rules in a top-down manner, which worked for the most part. But, when I was done, I realized that this methodology completely ignores the specificity of the CSS selectors. Each CSS selector has a specificity that is generally based on its use of IDs, classes, attributes, and elements.

value Since ColdFusion 9.0.1, CFScript has supported using a FOR-IN loop construct for both arrays and structures. In arrays, it loops over the indices; in structures, it loops over the keys. Typically, this is a clear-cut piece of functionality. But, when it comes to the Arguments collection, which exhibits both Array and Struct behavior, the FOR-IN loop can be a bit confusing. This duality tripped me up the other day.

value For years, ColdFusion has had the hash() function for taking variable-length string data and creating one-way "fingerprints" of the original value. This function has changed over time to include algorithm and encoding options; but, it has always worked with string data. Now, with ColdFusion 10, the hash() function has been enhanced to accept binary data (aka. byte arrays). This means that we can now create one-way "fingerprints" of binary values.

value I love Regular Expressions! I think they are the cat's pajamas. I use them all the time. That's why, when I saw that ColdFusion 10 had introduced a new Regular Expression method - reEscape() - I was eager to start using it right away. As you can guess from the name, reEscape() takes a string and escapes any special regular expression control characters found within the string. This creates a safe string literal than can be used inside of a larger regular expression pattern. Typically, when I ...&#160;<a href="http://www.bennadel.com/blog/2355-ColdFusion-10-reEscape-vs-Java-Pattern-s-Quote-Method.htm">Read More</a>&#160;&#187;

value I have traditionally been a fan of Tag-based ColdFusion programming. I think that tags are superior when it comes to integrating SQL scripting and HTML templating. With ColdFusion 10, however, I've needed to resort to Script-based programming as a means to include Closures and Function Expressions within my code. As I've made this transition, I've noticed a number of striki ...&#160;<a href="http://www.bennadel.com/blog/2354-ColdFusion-10-Script-vs-Tags-And-My-Coding-Methodology.htm">Read More</a>&#160;&#187;

value Yesterday, I was looking at ColdFusion 10's native WebSocket filtering functionality . It uses the special data key, "selector," as a way to define message filtering criteria. Last night, I started to think about how I could replicate this behavior in my WSApplication.cfc WebSocket proxy when it occurred to me that I needed a way to evaluate ...&#160;<a href="http://www.bennadel.com/blog/2353-ColdFusion-10-Creating-A-Simple-Expression-Evaluator.htm">Read More</a>&#160;&#187;

value In the ColdFusion 10 documentation regarding WebSockets, both the publish and subscribe functions mention that special data parameters can be used to filter incoming and outgoing messages.

value With ColdFusion 10's in-built WebSocket server, pushing messages from the server to the client is super simple. If you want to send a message to all users subscribed to a given channel. But, what if you want to push a message to just a single user? Limiting the scope of message broadcasting gets a bit more tricky. ColdFusion 10 has some sort of filtering mechanism built into the publish / subscribe feature-set; however, I was not able to get it working. As such, I came up with an alternate ap ...&#160;<a href="http://www.bennadel.com/blog/2351-ColdFusion-10-Using-WebSockets-To-Push-A-Message-To-A-Target-User.htm">Read More</a>&#160;&#187;

value By now, we're all used to ColdFusion's standard session management - the one that's typically powered by session cookies that get posted back to the server with every request. ColdFusion 10's built-in WebSocket server does not operate on cookies; instead, the client (browser) establishes a constant(ish) link to the server that creates a handshake using a server-provided ClientID. Unlike standard sessions, which are unique to a given user, a WebSocket session is unique to a given JavaScript ob ...&#160;<a href="http://www.bennadel.com/blog/2350-ColdFusion-10-Cross-Linking-Standard-Session-Management-To-WebSocket-Session-Management.htm">Read More</a>&#160;&#187;
