How To Create GStrings In Javascript By Extending Core Data Types
Posted: February 8, 2010 at 3:17 PM by Ben Nadel
This morning, I was looking at a tutorial on how to extend built-in Javacript objects by altering the Prototype of native Javacript classes. In doing this, you can add your own methods to Javascript String and Array instances (for example). The down side to this approach is that this affects every new and existing instance of the altered data type... read more »

What Happens When A ColdFusion CFLock Timeout Is Exceeded Without Error?
Posted: February 8, 2010 at 9:25 AM by Ben Nadel
Last week, when I was working on my jQuery Photo Tagger plugin (for Flickr-style photo annotation) , I was using CFLock to create thread-safe cache updates in the ColdFusion aspect of the code. As I was doing that, it occurred to me - I wasn't 100% sure what would happen if the timeout (indicated by the CFLock tag) was exceeded and no error was t... read more »

Programmatically Uploading Images To JING At ScreenCast.com Using ColdFusion
Posted: February 5, 2010 at 9:00 PM by Ben Nadel
Here at work, we use JING all the time to share ideas; it's by far the easiest way that I've ever seen to quickly take screen captures, annotate them, and then share them with other people. When capturing part of your screen using JING, you have the option to upload it ("share it") to ScreenCast.com. Doing this uploads the image to a unique URL ... read more »

Update: jQuery Photo Tagger Plugin For Flickr-Style Photo Tagging
Posted: February 5, 2010 at 10:26 AM by Ben Nadel
This morning, I worked on updating my jQuery Flickr-Style Photo Tagger plugin to get rid of some of the limitations with the initial release. I'm still kind of feeling my way through the plugin "best practices", so bear with me. Today, I made the following changes (the latest code can ... read more »

jQuery Photo Tagger Plugin For Flickr-Style Photo Tagging
Posted: February 4, 2010 at 10:21 AM by Ben Nadel
A few days ago, I programmed a little proof-of-concept for Flickr-style photo tagging using jQuery . I did it as an exploration in mouse-based event binding; but, it was a lot of fun and I wanted to see if I could take it a step further. So, yesterday and this morning, I packaged the jQuery code up into a jQuery plugin (phototagger.jquery.js), bu... read more »

Wrapping The Window Object In A jQuery Wrapper
Posted: February 2, 2010 at 8:21 PM by Ben Nadel
This morning, when I was building my Flickr-style photo tagging demo using jQuery , I got totally stumped trying to debug a variable problem. From what it looked like, the Window object appeared to be undefined within the context of my document-ready event handler. After picking apart the code and commenting out bits of it for like 10-15 minutes,... read more »

Creating Flickr-Style Photo Tagging With jQuery
Posted: February 2, 2010 at 2:38 PM by Ben Nadel
Lately, I've been experimenting with a lot mouse-move event-binding , which has led to some really cool internal stuff here at work. Building on top of some of that recent learning, this morning, I wanted to see if I could create a Flickr-style photo tagging effect using jQuery. I've never actually used the Flickr-photo tagging system, so the act... read more »

Calling jQuery's Data() Method Without Arguments
Posted: February 1, 2010 at 10:10 AM by Ben Nadel
With jQuery 1.4, I was very happy to see that they finally gave us the ability to invoke the data() method without arguments. Calling the data() method in this way returns an object containing all of the keys stored using the data() method on this object. When I was working on my jQuery image zoom experiment , I made heavy use of this feature to ... read more »

Is Simulating User-Input Events With jQuery Ever A Good Idea?
Posted: January 30, 2010 at 3:20 PM by Ben Nadel
The other day, I was having a discussion with Ryan Jeffords about programmatically simulating user-based input events with jQuery. Ryan was in the middle of building a very rich, very dynamic user interface for an eCommerce system's price adjuster module when he hit a bit of snag trying to programmatically simulate a user's click event on a che... read more »

Project HUGE: Deadlifts At 385lbs And Natural Hamstring Raises
Posted: January 29, 2010 at 6:08 PM by Ben Nadel
After deadlifting 365lbs two weeks ago , I was eager to try and push myself a little harder. Today, I built up to three work sets at 385lbs. After I hit the first set, I was super tempted to jump up to 405lbs (my new years resolution weight); but, it's a good thing I didn't - my form at 385lbs definitely leaves something to be desired. In the fol... read more »

Converting An IP Address To An Integer Using MySQL (Thanks Julian Halliwell)
Posted: January 29, 2010 at 8:30 AM by Ben Nadel
The other day, as an exercise in bit-manipulation, I tried using bit shifting to convert IP address values to integer numbers . In the comments to that blog, Julian Halliwell mentioned that MySQL has built-in functions for performing these conversions. I had never heard of these functions before, so I thought I would do a little playing. In the... read more »

Putting Your Geolocation iPhone Photos On A Google Map Using ColdFusion And jQuery
Posted: January 28, 2010 at 2:20 PM by Ben Nadel
I've been playing around with Google's map API lately and I have to say that I'm just blown away by how easy it is to use. And, not only how easy it is to use, but how easy it is to use in the context of your own applications. I've been looking for ways to play around with mapping and this morning, I started to think about my iPhone photos. I know... read more »

Delaying ColdFusion Session Persistence Until User Logs In
Posted: January 27, 2010 at 10:42 AM by Ben Nadel
In the past, I've dealt with creating dynamic session timeouts in my ColdFusion applications. I've typically done this to minimize the memory footprint created by site traffic spikes caused by bots (such as the GoogleBot) that spider the web site. Sometimes, however, I see that people want to delay session persistence in their ColdFusion applica... read more »

Converting IP Addresses To And From Integer Values With ColdFusion
Posted: January 26, 2010 at 9:02 PM by Ben Nadel
I've been playing with my bits a lot lately, parsing RGB colors and embedding secret messages inside image data ; but, bit manipulation is still something that feels somewhat awkward to me. I guess I live in a base10 (decimal) world and it's hard for me to think in terms of base2 (binary). As such, when a conversation about IP-to-Integer conver... read more »

Script Tags, jQuery, And Html(), Text() And Contents()
Posted: January 26, 2010 at 2:00 PM by Ben Nadel
The other day, Matt Olson left a comment on my jQuery and ColdFusion rating system post that the jQuery script I had was not working in Internet Explorer (IE). I confirmed this on my local copy and eventually narrowed it down to a discrepancy in the way IE can access the contents of a non-Javascript Script tag. Originally, I had been using the t... read more »
