I woke up at 3:50am this morning unable to sleep and by the time I got to work, I figured that was the worst thing that could happen today. Then I logged in to our CentOS kickstart machine to see how my “yum update” to CentOS 5.2 went last night and found all kinds [...]

When we rolled out our big Model-Glue/Coldspring/Transfer upgrade five months ago and ran into performance problems, we did some Craigslist shopping on a Sunday to buy some faster hardware that would hold us over until we could put a real fix in place. We have since acquired a couple of Compaq DL360G4s and I’ve [...]

Thanks to a tip from Elliott Sprehn on the Transfer list, I installed Java 1.6 u10 RC on my laptop to see how my Model-Glue/Transfer/Coldspring application performed with the JRE ClassLoader bug fixed. I’ve gotten in the habit of simply restarting my CF instance rather than reinitialize my application because it’s been faster in [...]

I don’t work with SQL Server much so I thought this might save someone else some effort when trying to figure out the right combination of CFQUERYPARAM and Transact-SQL keywords. We have a search object that stores keywords and want to loop over the keywords to create a dynamic search query against our full-text [...]

Update – this issue appears to be fixed with CHF3.
I’m testing an application on ColdFusion 8 in preparation for an upgrade and have found a strange error. My reinit process clears the trusted cache using the Admin API along with restarting Coldspring and Model-Glue. On CF7, the following code works very reliably:
<cfinvoke [...]

It’s pretty common knowledge that the Java 6 JRE in ColdFusion 8 has a bug from Sun that makes loading CFC-heavy applications slow. This impacts most framework-based apps that use Model-Glue, Mach-II, Coldspring, Transfer and so forth. To be clear, it’s not the frameworks, it’s a bug in the underlying Sun JRE.
I have [...]

In the same member merging process described in my last post, I was running a bit of code with a TRY/CATCH that looked for a duplicate primary key condition and, if found, deleted it from the source account:
<cfquery name=”select” datasource=”#variables.datasource.getName()#”>
SELECT *
FROM roles
WHERE id = ‘#id#’
</cfquery>
<cfloop query=”select”>
<cftry>
<cfquery name=”update” datasource=”#variables.datasource.getName()#”>
UPDATE roles
SET id = ‘#target#’
WHERE id = ‘#id#’
AND [...]

Something I learned today in my very rare use of CFTRANSACTION. I have a process that merges member accounts. This is needed when people create more than one account because they forget or can’t access their email account, etc. Because of the scale of this operation and it’s total behind-the-scenes nature, I’m [...]

After seven months of heavy development and a rocky-but-now-stable launch behind me, I feel like I have some command over Model-Glue (instead of the other way around). I am certainly no expert but I want to share a few of the things that tripped me up when I was getting started and solutions that [...]

Dan Switzer has been up to more good with jQuery releasing a multi-column dropdown plugin developed for Giva that can handle an arbitrary number of elements from a series of nested unordered lists.
There are two things that I like about this plugin in particular:

Full support for keyboard input
Designed to handle a lot of data

I have [...]
