In case someone out there was wondering, I had to give up on blogging my sessions from CFUnited when my laptop decided to start spazzing out. I'm not sure if I need to download more updates or what, but it would randomly rev my fan, and it was making enough racket that I had to stop using it during sessions.
So much for that.
I did have a blast though. I went 4-6 for stumping Adobe guys on why
This contains info from the CFUnited talk on this topic.
This talk covers MVC, Factories, ORM Introducing a quick start application: AppBooster
Domain & Business objects for each Entity.
Business Object (bean) - people, places, and things, the nouns in your system. Data Access Objects (DAO) - read and save objects Gateways - Objects which return queries Service Object (SO) - your API (controllers do not touch BO, DAO, or Gateway) Controllers - talk to your service layer.
Q: Where is validation at? A: In the BO, or the SO.
Frameworks and Software Layers
DB Layer (ORM) Transfer, Reactor

Last night myself and a couple of coworkers got together to do a study session for our ColdFusion Certification test. One of the topics we discussed was error handling, and the question of how to use them came up...
I updated the CFRegEx Tester to catch and display error messages generated ColdFusion. Sorry to whoever it was that was hitting error messages.
I don't know about you, but my company uses the IsDate() function for a lot of simple validation of date inputs, and it works fairly well for the most part. The only problem I have with it is that when paired with SQL Server (2000 or 2005), it still can't capture all invalid dates.
The date 'January 5, 753' is a valid date, but attempting to insert it into a SQL Server datetime object throws an error because valid dates for SQL Server are between January 1, 1753 and December 31, 9999. Dates above the year 9999 are caught by IsDate(), but the lower bound is not.
Nothing that someone else couldn't write, but useful. to save headaches.
I built a simple regular expression tester for ColdFusion to test out how CF matches regular expressions (not well). You can find the CFRegEx Tester at... well at that link.
While ColdFusion uses cookies in some sophisticated ways (tracking sessions and what not), I found out today that because CF is case insensitive, it is inept at tracking cookies in certain situations.
God to I hate this message. There are a 1,001 questions about the cause of this message on the CF 6.1 livedocs for the
cfimage, CF8, Java in ColdFusion, ColdFusion
One of the big frustrations about CF8 image effects, is the lack of any way to get transparent writes or backgrounds. While most people think of transparent as just one more color, when you look at how Java handles pixels, you'll understand why Adobe didn't take the time to do this themselves.
I know I said that I wouldn't do it, but I've become obsessed with figuring out replicate the rounded borders effect for CF8 that Foundeo included in its Effects CFC. I tried drawing rounded rectangles with large brush strokes to do it, but I keep messing up the diameters... maybe I'm just not getting it right.
Any one have any ideas?
If it proves too annoying, I'll get rid of it.
