The following article is a compilation of Ben Forta's blog entries from his ColdFusion 8 usergroup tour.
ColdFusion 8-Supported Image Formats
Lots of you have been asking about ColdFusion 8's planned <CFIMAGE> tag, wanting to know what image formats will be supported (many of you are asking about GIF and PNG specifically). As long as you keep in mind that ColdFusion 8 is a work-in-progress and that features and specs can change...
ColdFusion 8 has two new functions: GetReadableImageFormats() returns a list of the supported readable image formats, and GetWriteableImageFormats() returns a list of supported writable formats. The following code snippet shows all supported formats:
Readable (#ListLen(r)#): #r#<br>
Writeable (#ListLen(w)#): #w#<br>
Running this code (in Beta 2, remember, this can/may still change) displays the following:
Readable (15): BMP,GIF,JFIF,JPEG,JPEG 2000,JPEG-LOSSLESS,JPEG-LS,JPEG2000,JPG,PNG,PNM,RAW,TIF,TIFF,WBMP
Writeable (15): BMP,GIF,JFIF,JPEG,JPEG 2000,JPEG-LOSSLESS,JPEG-LS,JPEG2000,JPG,PNG,PNM,RAW,TIF,TIFF,WBMP
And, yes, GIF and PNG are both supported (both read and write).
Getting Started with the ColdFusion Debugger
After a seven-year hiatus, ColdFusion once again has an interactive debugger, and this time it's built on top of Eclipse (and uses the same debugging interface as Flex Builder and other Eclipse plug-ins). If you are interested in taking the debugger for a spin, here's what you need to know to get started:
First of all, you need ColdFusion 8. If you don't have it yet, get it here: http://labs.adobe.com/technologies/coldfusion8/.
You'll also need the ColdFusion 8 Eclipse extensions, and these must be installed (here is some installation help: www.forta.com/blog/index.cfm/2007/5/30/ Installing-ColdFusion-8-Eclipse-Extensions).
Before you can use the interactive debugger, enable debugging support in ColdFusion. Here's what you need to do:
- Open the ColdFusion Administrator.
- Select "Debugger Settings" in the "Debugging & Logging" section.
- Check "Allow Line Debugging".
- The debugger needs a port to communicate over. If you can't use the default, change it (just be sure to use an unused port, and you can't use the port that ColdFusion itself is on).
- By default, ColdFusion allows up to five concurrent debugging sessions; you can raise or lower this value as needed.
- Click "Submit Changes" and restart ColdFusion as you are instructed to do.
Now that debugging is enabled, configure Eclipse to tell it which ColdFusion server to debug against. Servers need only be defined once, and once defined you may debug against them as needed. You can define as many servers as you need, local and remote, as long as the server has RDS enabled (and you have an RDS login).
The first thing you need to do in Eclipse is define the RDS settings for your ColdFusion server. These settings are used by the debugger, as well as the wizards, RDS panels, and more. To define your RDS connection, do the following:
- In Eclipse, select Window->Preferences to display the Preferences dialog.
- Select ColdFusion in the tree, expand the selection, and select RDS Configuration.
- Click New to add a new server, or just select any server to edit it.
- Provide a description, host name, port, and login details, and then save. To use your local ColdFusion server, specify 127.0.0.1 as the Host Name, 8500 as the Port (if using the integrated HTTP server), leave the Context Root blank, and provide the login information.
- Click "Test Connection" to make sure the RDS connection is working, and then click OK.
Now that your RDS connection is defined, define the ColdFusion servers you wish to debug against. Here's what you need to do:
- Locate the Debug button in the toolbar; it's the one with the little green bug on it.
- Don't click the button. Instead, click the down arrow to the right of it and select "Debug..." to display the Debug dialog, which is used to manage debugging configurations.
- The Eclipse debugger is used to debug all sorts of applications created in all sorts of languages, and along the left of the dialog you'll see a list of application types that can be debugged. Select "ColdFusion Application".
- You'll see any defined ColdFusion debugging servers under the "ColdFusion Application" branch. To add a ColdFusion server, click the New button (the leftmost one above the list) while you have "ColdFusion Application" selected.
- Name this server and then select the RDS server to use from the dropdown list.
- If you are debugging against a local server (running on the same machine as Eclipse), you can ignore the mappings section. If ColdFusion is on a remote server, you'll need to define mappings here.
- Click "Apply" to save your changes.

Question: I'm pretty new to ColdFusion, but am more experienced running J2EE type boxes. I'm trying to set up a ColdFusion dev server on a VM with limited memory, and I'm trying to trim it back so that it doesn't pork out and use every bit of memory on any computer within a 10 mile radius. I.e. trying to get it so that it perhaps doesn't fire up all of the Flash remoting servlets or other things I don't need for basic CF functionality, in hopes that this might trim back the RAM usage. Any help you might be able to be on this?
In his session at @ThingsExpo, Tony Shan, Chief Architect at CTS, will explore the synergy of Big Data and IoT. First he will take a closer look at the Internet of Things and Big Data individually, in terms of what, which, why, where, when, who, how and how much. Then he will explore the relationship between IoT and Big Data. Specifically, he will drill down to how the 4Vs aspects intersect with IoT: Volume, Variety, Velocity and Value. In turn, Tony will analyze how the key components of IoT influence Big Data: Device, Connectivity, Context, and Intelligence. He will dive deep to the matrix...

When it comes to IoT in the enterprise, namely the commercial building and hospitality markets, a benefit not getting the attention it deserves is energy efficiency, and IoT’s direct impact on a cleaner, greener environment when installed in smart buildings. Until now clean technology was offered piecemeal and led with point solutions that require significant systems integration to orchestrate and deploy. There didn't exist a 'top down' approach that can manage and monitor the way a Smart Building actually breathes - immediately flagging overheating in a closet or over cooling in unoccupied ho...

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
