CFML Request Parameters

By barneyb on June 23, 2009

If you've worked with ColdFusion (or CFML) for very long, you've probably noticed that CFML's treatment of request parameters is a little unorthodoxed.  Specifically, it doesn't differentiate between multiple instance of the same parameter being passed.  Consider this url:
page.cfm?a=1&a=2&a=3,4&b=5
As you can see, there are three instances of the 'a' parameter, one of which has a [...]

ColdFusion Struct Literals Are Not Thread Safe (CFML Ones Are)

By barneyb on June 19, 2009

If you read my blog regularly or follow me on Twitter, you know how much I hate Adobe's quasi-implementation of struct (and array) literals.  I'm really hoping "third time's a charm" and CF9's implementation is sane.  The gripe is that this code:
<cfset s = {
name = "barney",
age = 29
} />
is executed [...]

Riddle Me This, CFLOOP

By barneyb on June 17, 2009

Take this simple loop:

#i#

What is the output?  My answer is the numbers 1-3 followed by 7-10.  But I was dismayed to learn this evening that it doesn't seem to be the case on my server.  There it outputs 1-10 with no breaks.  Can someone please [...]

An Ink Free Year

By barneyb on June 11, 2009

Yesterday I turned 29.  One year older on the clock, and about 20 years older in effect.  I'd planned on getting a leaf tattooed on my right calf as a birthday present, but like so much else, it didn't work out.  Since I turned 18, I've gone and had birthday tattoos more than half the [...]

jQuery TableSorter Comma Parser

By barneyb on June 3, 2009

Last night I needed a simple HTML table with sortable columns, and after a quick Googling, found the TableSorter jQuery plugin.  I'd come across it before, but never actually used it.  Added a class to my table (for targeting and to leverage the CSS that it comes with), added the required line of JavaScript to [...]

First Person Documentation

By barneyb on June 2, 2009

I'm not sure when I started, but I've documented things in the first person for quite a while.  Fusedocs promoted this format, and was probably a significant influence, though I recall doing it back in college as well.  It's clearly not new or uncommon, but I just had a gentleman email me about it (based [...]

Shoot the Engineers

By barneyb on May 26, 2009

About a week ago, Marc Funaro wrote an interesting blog post about CFML and OO.  The prevailing opinion (via Twitter, blogs, etc) is that Marc is incorrect/inaccurate/inexperienced/whatever, and I disagree completely.  He hit the nail on the head.
HTTP is a stateless, request-response environment.  Nearly all web applications interface with a SQL database, which is also [...]

My First cf.objective()

By barneyb on May 26, 2009

I know I'm late to the "cf.objective() recap" party, but I've been both crazy busy and rather tired, so I haven't got to it until now.
First, I'd never been to Minneapolis before, and from the little I saw, it's a pretty nice place.  Obviously I missed the "buried under snow" part, and that definitely puts [...]

FB3lite as a Custom Tag

By barneyb on May 22, 2009

Last night at work Koen uncovered an issue with using FB3lite as a custom tag.  Inside the tag it does "formUrl2Attributes" to merge the two scopes into the attributes scope.  What I'd done incorrectly was omit the "don't override" parameter to the structAppend calls, so the URL and FORM scopes would supercede any existing attributes [...]

Effective Photo Manipulation

By barneyb on May 21, 2009

Image manipulation is a common tasks for web applications, usually centered around creating and managing thumbnails (of photos, PDFs, videos, whatever).  Photo manipulation is a subset of image manipulation, and has a couple aspects that differentiate it other types.
First and foremost, photo quality is of high importance.  Contrast this with creating a thumbnail of a [...]
