What's an Object?

What started as a simple blog entry quickly became quite lengthy, so I'm posting what I hope will be the first in a series of introduction to object-oriented programming for ColdFusion programmers articles as a PDF.


Please feel free to comment, correct, scrutinize, and ask questions as needed!

Thanks for writing this piece and I look forward to any future ones!


Ben Forta blogged this. that's how I found it.


Excelent Matt, While this was not new to me, this is the first time I gained a real understanding of it. You have a great way of explaining. Really looking forward to the future "follow ups".


Thanks everyone--appreciate the feedback!


I was looking for a OO explanation in a CF way... and this is it... (and like Trond... I'm really looking forward for more.) Thank you


Hi Matt, Good show on the article! I am looking forward to seeing this blog in Flex calling CFCs through Flash Remoting. :)


Thanks Mike--getting that up and running is definitely on the roadmap! The code's done, just have to find the time to clean it up a bit and get Flex installed on this server. I'm putting it on Tomcat so I'm sure I'll have some tales to tell going through that experience ...


I too would like to express my congratulatory remarks on a well written article. I am definetely looking forward to your next one, just don't wait too long to release it! :)


Great article, I look forward to more in the future. I have been trying to get my head aroung CFC's and OOP in general for some time. Your first article reienforce what I have picked up todate, and added some depth to what an Object is. What I look forward to hopefully in a future article is something along the lines of "OK, now you know what an object is, here is how you find them in the requirements for an application and get them to work together to acomplish said applications goals."


Thanks for all the nice feedback. Ian, what you're discussing, specifically OO design, is probably the hardest part of OOP. I'll definitely be addressing it, but a very, very firm foundation needs to be in place first, so it will come late in the series of articles I have planned. As a preview, the next article (no timing on it yet) will likely be along the lines of "OK, now I know what an object is ... how do I use one in the context of an application?" This will be really simple stuff but will help build a foundation so everyone can start seeing objects in their apps as Ian points out. It's fantastic to see so many CFers interested in this!


Nice job, Matt!


Great introductory article. I'm glad to see that you are not stuffing all your bean properties in to the "this" scope like I've seen so many other people do.


Matt, Thanks for writting this article!


Great article Matt! I know Im late to the table, but this has actually helped me see that I've been going about OOP all wrong. ;) Now I know how to start looking at it. I've always tied my DAO's and my BO's to my databases like there was some sort of magical mystical invisible binding between them (Procedural Programmer stuck in an OOP world). I now see how I should be looking at it and have found a new excitment for trying. :) Thanks again!

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …

Setting Up Django On a Raspberry Pi

This past weekend I finally got a chance to set up one of my two Raspberry Pis to use as a Django server so I thought I'd share the steps I went through both to save someone else attempting to do this some time as well as get any feedback in case there are different/better ways to do any of this.

I'm running this from my house (URL forthcoming once I get the real Django app finalized and put on the Raspberry Pi) using dyndns.org. I don't cover that aspect of things in this post but I'm happy to write that up as well if people are interested.

The Definitive Guide to CouchDB Authentication and Security

With a bold title like that I suppose I should clarify a bit. I finally got frustrated enough with all the disparate and seemingly incomplete information on this topic to want to gather everything I know about this topic into a single place, both so I have it for my own reference but also in the hopes that it will help others.Since CouchDB is just an HTTP resource and can be secured at that level along the same lines as you'd secure any HTTP resource, I should also point out that I will not be covering things like putting a proxy in front of CouchDB, using SSL with CouchDB, or anything along those lines. This post is strictly limited to how authentication and security work within CouchDB itself.CouchDB security is powerful and granular but frankly it's also a bit quirky and counterintuitive. What I'm outlining here is my understanding of all of this after taking several runs at it, reading everything I could find on the Internet (yes, the whole Internet!), and a great deal…
