One thing that I find intriguing about inheritance in Javascript is that it is object-based. Meaning, you inherent from an actual object instance, not from a class. This is known as Prototypal inheritance, sometimes referred as differential inheritance, in which your class contains only that which differs from your prototype object. In this form o... read more »

Parsing Invalid HTML Into XML Using ColdFusion, Groovy, And TagSoup
Posted: September 30, 2009 at 2:26 PM by Ben Nadel
I try to write my HTML as XHTML-compliant as possible, which makes it a subset of XML; but, that's not always easy or possible and often times the HTML that we deal with is downright dirty. As such, it makes parsing the HTML into a usable data structure a total nightmare! As part of my exploration of Groovy, I wanted to see if ColdFusion could lev... read more »

Thoroughly Document Your Use Of ColdFusion's CFHTMLHead Tag
Posted: September 29, 2009 at 10:12 AM by Ben Nadel
The other day on Twitter, I saw someone tweet about how they just discovered ColdFusion's CFHTMLHead tag and was planning to use it in a project. This gave me flash backs to a project I took over in which the CFHTMLHead tag was being used all over the place. Having not known about this tag at the time, I thought I was going crazy!!

Posted: September 22, 2009 at 10:17 AM by Ben Nadel
Ben, How would I go about splitting a list into multiple lists? For example I have a list: 07/08/2009|1,573,067.20|8/8/2009|1,563,000.20 This list can be infinite in values but will always contain a date/amount combination.

Groovy Operator Overloading Does Not Work In The ColdFusion Context
Posted: September 18, 2009 at 10:15 AM by Ben Nadel
Disclaimer : I just started looking into Groovy so a lot of this might be dead wrong. When I watched Barney Boisvert talk about Groovy, one of the first things that I wanted to try was operator overloading. It's been a really long time since I've played around with a programming langauge that even allowed it, so the prospect of implicitly ... read more »
