CFML 101 - Grouping arrays for column presentation

This is an idea I got from a Ruby on Rails extension called in_groups_of.

Basically the idea behind this method, is to be able to get an array of any size, and split it up in groups of arrays with smaller sizes.

One application that keeps coming back over and over again, is the ability to display tabular data in columns instead of rows.

Imagine the following array as an example:

CFEclipse 1.3.5 Released

(Photo: TalkingTree)

It just came to my attention that CFEclipse 1.3.5 has been released, and as usual I am a bit late announcing it.

From the what's new page, we can see that loads have been added to it, but the highlights in my opinion are:

1. Proposal Categories
2. Function Proposals
3. An option to automatically format code
4. Occurrence marking, which will automatically highlight all the occurrences of a selected string
5. Opening Files from the OS (CFEclipseCall)

Two new and free ColdFusion services for you!

So I've been playing with Google App Engines, and decided to create two projects in favour of our beloved ColdFusion.

I know there's tons of that stuff around the web, but I wanted to make one that would actually help people from all levels. I'll put their URL's here first, so you can cease your curiosity, and then I'll explain more as we go.

Creating new ColdFusion 8 instances - The easy way - Appendix

Following Andy Allan's comment on my previous post, I decided to write a new post and make some things clear here.

Basically, if you do check "Create Windows Service", your new instnace will automatically be created as a Windows Service. It's not too bad, as you would normally want your new ColdFusion instance to start-up with your server.

Creating new ColdFusion 8 instances - The easy way

I just had to write this guide at work, and thought it could be useful to somebody else.

Basically at work, we have ColdFusion 8 installed on each developer's computer, and in order to have everything separated, we have one ColdFusion instance per project, so we can save on resources, and can fine tune each of the instances according to the application needs.

There's a few ways to accomplis this task, but lately I found that the easiest way if to use ColdFusion Admin itself, and let it do all the work for you. here's how I do it, assuming you have ColdFusion 8 multi-server configuration already installed:
