Larry Ellison of Oracle thinks they're gibberish. Microsoft thinks they should look exactly like Microsoft products but skinned in the Clear October Sky. Sun thinks it's still a jump ball and would like your input . Amazon likes to call them by their Web 1.8 name: Web Services and Google thinks of them as just another engine for developing "do no evil" ... meanwhile a bunch cloud-minding developers flame each other into vaporocity over a TOS that claims "clouds should not and will not be owned". And yes, vaporocity.com was still available at the time of this writing.
As with a lot of tech buzzwords, cloud computing is fast becoming the one-size-fits-all-goto phrase for anything tech. And indeed Mr. Ellison was right in pointing out that cloud computing has been redefined to include everything we already do. But he fails to grasp or at least acknowledge that it's everything we already do to the nth degree ( at least for all practical purposes ). And for a fraction of the price to boot! So while Larry contemplates changing the verbiage in some of his ads, us developers should take a page from Thorsten over at rightscale.com to figure out where what we do on a day to day basis fits in because the bottom line, literally and figuratively, will someday reside in the cloud.

How Amazon Web Services needs to help Flex Developers
Or How Amazon Web Services can implement a Flash Proxy Service.
There’s been a thread at the amazon simpledb forums discussing that AWS should implment a crossdomain.xml file. I agree that AWS should open up their public facing services to flex developers by implementing a crossdomain.xml file however, simply implementing a crossdomain.xml file will not address the real problems of authentication and security.
The real problem facing flex developers is that it’s not secure to place your amazon secret key inside of a compiled swf. It can easily be decompiled. It’s been suggested that the best solution is to proxy calls through a server, such as an EC2 instance. For just wanting to store and recieve data in S3 or SimpleDB that is just way too much overhead.
The solution is for Amazon to implement a flash proxy service for flex developers. ( and silverlight )
- Flex devs need to register the domains that are associated with thier access key. ( www.mydomain.com )
- Flex devs then only need to send thier access key along with each request.
- The amazon flash proxy service then verifies the domain the request is coming from is in the list of verified domains for that accessky and adds the secret access key to the request before sending the request on it’s way.
- Any requests that come from domains that use an access key outside the list of domains gets denied.

Loading Remote Modules in Adobe Air Applications
I do not mean for the following post to be a permanent solution. More than likely this issue will be addressed in future releases of the flex and air sdk’s. I just need something right now and have not been able to come up with a good working solution. In fact, I hope that someone smarter than I can come along and point me in a better direction.
The Problem : You created an AIR application that you want to distribute and you want to load modules remotely over the network or the network. It offers advantages over using the air Updater classes, mainly you can update the module without asking the user to update the installation.
The Issues : Loading a remote module is a security issue. I first tried to use an <mx:ModuleLoader> tag in my air application and pointed it to my local web server. It did not work. I thought it was a crossdomain.xml issue. and eventually stumbled upon this example
Which is forcing a download of the crossdomain.xml. It did not work. My next attempt was to download the module and attempt to load it as bytes. I tried multiple variations of this, even tried saving the file to the File.applicationStorageDirectory. It did not work.
I came across these two articles as well:
Remote Plugins and Modules in AIR by Ethan Malasky
Loading Modules / Runtime CSS into an Air App by Dan Shultz
A Solution : What I finally settled on was using the HTML class in air to load a remote application and then talking back and forth using LocalConnection.
Module App ( you can’t have this swf running on your machine if you want the Air app to work)
While it’s not a perfect solution, it did allow me to accomplish what I wanted to do. Load remote modules in air and talk back and forth As I said in the beginning of this post. I do not think this will be a permanent solution.
Final thoughts on LocalConnection class.
– you only need one local connection / swf. The swf connects to the name of the connection it wants to collect messages from. Other swfs just need to know the name of the connection to send to.
— you set the client = to the context you want the code to be run.
— the underscore “_” on a preceding connection name is a convention in the docs that allows you to circumvent having to know the domain. Otherwise it’s something like mydomain:connectionName.
— allowDomain(“*”) and allowInsecureDomain(“*”) allows you to define what domains can send messages to the receiving local connection.

Flex BreadCrumb Navigator with Degrafa
I was able to catch a degrafa connect session last month in Denver and have been tinkering part time with the framework since then and I had a need to put together a bread crumb (like-ish) navigator so I decided try and use degrafa skinning to get a better look and feel, and it was surprisingly easy! Go Team.
At any rate, this was my first attempt at a BreadCrumbNavigator. I used ComboBox’s, because the lists are gonna have to be filter-able, but for now that code isn’t complete, yet. And also parts of the style is defined in the skins, so I’ll pull them out.
Here’s an example. Here’s the code.

Displaying Character Codes in Flex
If you are capturing keyboard events and want to display the Character Code as Text all you need to do is use String.fromCharCode( …charCodes ) as in the following:
private
function keyDownHandler(event:KeyboardEvent):void{
textInput.text = String.fromCharCode( event.keyCode );
}
Don’t you just love searching and searching for something that should be real simple and then feel like this:
