CFThread - Don't Abuse It
I love the fact that you can now create threads with CFML in ColdFusion 8, however as Spiderman can tell you with great power comes great responsibility.Using threads can increase the performance of your application, however using threads can also decrease performance.

Serializing CFC's in ColdFusion 8
One of the handy new features in ColdFusion 8 is that CFC's are now serializable. There isn't a whole lot of information about this new feature in the docs, but I did some playing around and it does appear that they have used Java's serialization API. This means that you can use java's java.io.

Getting the Application Root Path in ColdFusion
I wrote a handy function today that will return the server file system path of the acting Application.cfm file for a ColdFusion application. It works by working its way up the directory tree until it finds an Application.cfm file. If it doesn't find one it will throw an exception.

Application.cfm and AJAX
I had someone email me with the following question today:I'm developing a ColdFusion app with Prototype. Seems Ajax.updater wants to insert my application.cfm code into my div along with responseText. How can I stop this?
This question brought up two good points.

I am happy to announce the latest creation from foundeo: fusionKit.fusionKit is a CD full of some handy ColdFusion components and UDF's. It is a similar concept to the DRK's that Macromedia used to sell, but is it's 100% ColdFusion.

Floor Function in ColdFusion is Int
Those of you coming from programming languages that have a floor function, may be hard pressed to find it in ColdFusion - that's because it's called Int.The Int function will take in a floating point number chop off the decimal part, leaving you with just the integer part.

CFDocs.org back up and running
Several people have emailed to tell me that cfdocs.org was down. I have moved it to a different server, and it is now back up and running.If it's still not working for you give the DNS some time to propagate.

Textile for ColdFusion
A few weeks ago I mentioned that I had an open source project in the pipeline. Well I've been really busy so I haven't had a chance to release it until now...I built a UDF for converting textile markup into HTML markup.
You can learn more about textile here.

Use CFSILENT
Here's my tip for the day. If you have a choice in using either the cfsilent tag, or cfsetting enablecfoutputonly="true" use cfsilent.Here's why
Easier to type
Easier to read
The enablecfoutputonly gets very messy when used across cfincludes.

ColdFusion debate on digg
I was surprised to find that my AJAX zip code example made it on digg today. I was wondering why I was getting so many blog comments today...Anyways since I used ColdFusion in this example you will find some debate on ColdFusion in the comments on digg.

Null Java References in CF 6 vs 7
ColdFusion 7 appears to be much better at passing null values to a java object. ColdFusion 6 however likes to block you from doing it, even when you want to.I am tring to work with a java API that requires me to pass a null value to a method.

It has been a while since I've posted one of these java + cfml tricks, so here's a neat one for ya'.You can use the Java Naming and Directory Interface (JNDI) to perform a DNS query in ColdFusion.

Want additional DB or OS support in ColdFusion?
Are you burnin' for built-in PostgreSQL support in Macromedia ColdFusion (BlueDragon already has this)? How about FreeBSD? Debian Linux Support? Fedora Support? Additional J2EE servers? 64-Bit Operating systems?Then go and take the ColdFusion vendor support survey.

Build a directory browser with ColdFusion
Most web servers have directory browsing disabled, but sometimes you want it to work for certain directories. Most web servers also allow you to setup specific settings for your directories for instance you could do it with an .htaccess file on Apache.

RDS Security Problems?
Erki Esken posted a comment on Ben Forta's blog asking if the source to the RDS plugin for Eclipse would be released. Forta's response was:"But, my gut feel is that it would not be a good idea to fully expose the source for RDS as that may create potential security problems.

Cheat Sheet Roundup - Over 30 Cheatsheets for developers
Lets face it, unless you have a photographic memory, no developer can remember all the different functions, options, tags, etc. that exist. Documentation can be cumbersome at times, thats why I like cheat sheets.

CodeFetch
CodeFetch is a clever little app that searches published books for code samples matching your search. So if you search for cfmail you will get code samples from several books on ColdFusion. You can then of course buy the books through amazon.

ColdFusion Jobs
The indeed job search engine has a pretty cool feature that you can add to your site, called job rolls. So for instance if you have a coldfusion site, and want to list coldfusion jobs then, you can paste in a job roll for coldfusion jobs:Jobs from Indeed

New Poll: Do you use RDS?
I have added a new blog poll titled Do You Use RDS? I'm just curious how many people use it. There are lots of reasons not to use it, but I think its still pretty popular.Here's why some people might use it:
Easy way to edit files on a remote server.

The client variables debacle
Nathan Strutz recently said that client variables are no good to use. From reading his entire post, he isn't saying that the concept is flawed, just the current implementation. He even suggests how they may could be improved.

Macromedia Example Applications
Looking for example applications built with Macromedia products? I found this list of Macromedia sample applications in the del.icio.us side bar on cfmx.org.
There are Flex, Flash, ColdFusion, and Dreamweaver example apps there.

cfmx.org
I have owned the domain cfmx.org for a while now, and I have had a lot of ideas for what I can do with it. But I wanted to start using it, so I whipped up a ColdFusion only aggregator portal a few weeks ago.

Installing multiple versions of CFMX on JRun
I like to setup my development machine with different versions ColdFusion, but all with the same web root. I setup a server for each instance, so I can use the same url on different ports (eg CFMX 6 on port 8600, CFMX 7 on port 8700, etc).

Parsing RSS 1.0 with ColdFusion MX
Well thanks to Sean Corfield I understand why I was having issues with namespaces when trying to parse RSS 1.0 with XPath.If you have a document with namespaces such as RSS 1.

RSS and XPath
I came across a handy reference article on xml.com today that gives XPath queries for RSS and Atom feeds. Just last week I was attempting to parse a RSS 1.0 feed in CFMX using the XMLSearch function. I'm running into problems however due to the name spaces in RSS 1.

Using Java Web Services with CFMX
JWS files are nothing more than a Java class with a .jws extension. But when placed on a web server with Axis installed (such as ColdFusion MX), you can expose that class as a web service. This works just like CFC's do in ColdFusion. Here's an example JWS we will call CaseService.

CFC's - private works like protected
I noticed yesterday that when you use access="private" in a CFC function, inherited CFC's also have access to this function.In object oriented languages such as Java, C++, or C# this type of access is known as "protected" access.
