Where Are The CTRL-S, ALT-TAB, F5 Web Frameworks?

By barneyb on October 26, 2009

Ok, people, where are all the web frameworks that will give me a CTRL-S, ALT-TAB, F5 workflow?  As I've been shopping around, it seems everything requires more than that.  Some places you can script the additional steps into the refresh, but not always.  Am I the only person that doesn't want to have a million [...]

Rebuilding Pic of the Day

By barneyb on October 21, 2009

I need some help, thoughts, recommendations as I undertake this, but first some background…
As I do every 15-18 months, I've decided that it's time to rebuild Pic of the Day.  I've never actually done it; the codebase is still the same one I started 5-6 years ago and have edited (often daily) since then.  But [...]

CFYourFavoriteJVMLanguage

By barneyb on October 9, 2009

Just in case you didn't come to my talk on leveraging Groovy in your CFML applications at CFUnited, I wanted to share this simple CFM page I demoed:
<cfimport prefix="g" taglib="cfgroovy2″ />
<cfscript>
myArray = [
"barney"
];
</cfscript>
<!— thanks Groovy —>
<g:script>
variables.myArray.add("heather")
</g:script>
<!— thanks Quercus —>
<g:script lang="php">
<?php

CFGroovy2 and Ehcache

By barneyb on September 26, 2009

Until this point, CFGroovy2 has used a custom WeakHashmap/WeakReference caching mechanism for compiled scripts.  It works, and it ensures that the script cache won't run your JVM out of memory, but that's about it's only selling point.
Today I plugged in Ehcache as an optional caching backend if it's available on your classpath.  When CFGroovy2 spins [...]

Custom Scopes for CFGroovy2

By barneyb on September 26, 2009

The middle of last week I committed an update to CFGroovy2 to allow an arbitrary number of scopes to be passed in as attributes, just like you have always been able to do with the 'variables' attribute.  If you update, the change is the addition of lines 47-51:
<cfloop list="#lCase(structKeyList(attributes))#" index="scope">
<cfif listFind("language,lang,script,variables", scope) EQ [...]

Edit Distances Bug

By barneyb on September 25, 2009

This evening I found a bug in one of the optimizations that I made to the edit distance function.  I've corrected the code in the original post, and made a note of the change there as well.  Just wanted to mention it in a second post so anyone who read via RSS will be aware [...]

Edit Distances and Spiders

By barneyb on September 24, 2009

An edit or string distance is the "distance" between two strings in terms of editing operations.  For example, to get from "cat" to "dog" requires three operations (replace 'c' with 'd', replace 'a' with '0', and finally replace 't' with 'g'), thus the edit or string distance between "cat" and "dog" is three.  Aside from [...]

Groovy Objects in CFML (a la Ben)

By barneyb on September 17, 2009

Ben Nadel posted an interesting article over on his blog titled Instantiating Groovy Classes In The ColdFusion Context where he demoed how to create a class factory in Groovy and invoke it from CFML to insantiate new instances of Groovy classes without actually reentering a Groovy context.  I wanted to expound on what he demoed [...]

This Is Why Groovy Rules

By barneyb on September 10, 2009

So I have a collection of newsletters, and each newsletter has a collection of articles.  Each article, in turn, has a collection of authors and a collection of categories.  Now what I need to do is get a list of unique handles for all the authors and categories for a given newsletter.  Here's the CFML [...]

LessCss for CFML Developers

By barneyb on September 8, 2009

LessCss is a nifty extension to the core CSS language to support variables, calculated values, inclusion-by-reference, nesting, and some other goodies.  Basically the idea is to simplify and reduce duplication in large stylesheets.  Here's a simple example of a variable and a computed value:
@color: #fdd;
#header {
background-color: @color;
color: @color / 2;
}
That translates [...]
