I’ve been playing around in the Clouds again, this time I’ve been giving the Amazon EC2 Railo instance a run.
Following a great tutorial on getting an EC2 instance up and running, I had a publicly accessible website and the developer version of Railo running in about 20 minutes.
After tweeting about my instance, I returned to the website overnight to find my developer version of Railo had outgrown its maximum 10 ip limit.
The initial experience in getting Railo up and running in the cloud was a good one. As I struggled to upgrade my developer version of Railo to the community edition and contacting Railo support, I realised it wasn’t going to be that easy.
I’ve decided to install Railo locally and investigate it a bit more in the comfort of my hard drive. I’ll stick to experimenting in the Stax cloud at the moment, which I’ve found to be a more streamlined process.

I’ve just come down from a little experiment in the clouds.
I received my invitation to the Stax beta today, and was a little too keen to get my hands dirty.
I gave myself a quick 15 minutes to write a simple weather application, and deploy it to the Stax Cloud (I had already created my application and downloaded a local development version via the Stax SDK). In short, Stax is a breeze to use and I think it will become a very compelling platform in the future.
The Stax Cloud allows you to easily deploy web applications straight to Amazon EC2. You can deploy many popular Java based technologies including ColdFusion and Flex.
It’s the first platform I’ve seen allowing you to deploy the Adobe ColdFusion application server to the cloud. Other than Stax, I’ve only heard of Railo being deployed to Amazon EC2 because of all the licensing problems with Adobe ColdFusion. I still haven’t investigated how Stax are overcoming the licensing issues (that’s on my todo list).
You can visit my weather application, and I managed to get it done within 15 minutes.
I really like the Stax Cloud. It makes it so simple to get an application up and running, which essentially is an Amazon EC2 instance. I’ll definitely keep playing around with this technology.

I just signed up to twitterfeed.com to alert all of my twitter friends, about any blog posts I make.
Not quite sure how it is going to work yet, but the process seemed simple enough. I guess this will be the first blog post that automatically reaches Twitter!

We currently have an interesting problem with Google Earth. There is a nice big cloud directly over a location we want to zoom in on.
The strip of cloud appears directly on top of the location we’re interested in, and it is proving rather annoying!
Google hasn’t updated this part of the world (or specifically this strip) for quite some time, so I thought I’d dig around to see what I could find out about the frequency of updates to the satellite imagery.
I found some interesting information, but in short, I didn’t find any real public information about how and when Google update the imagery, or what the selection criteria is (blurry vs obstructed, etc). It all seems rather random.
I should probably use the database report page, maybe Google might pay attention to this one silly strip of cloud? I can’t even imagine how many reports they receive to fix insignificant strips of the earth.

The term random denotes any control over the outcome, frequency or chance of reoccurrence. However, as programmers sometimes we need the ability to persuade a particular reoccurrence to be more or less frequent.
A common and easy method to randomly pick an item from a list, is to use an Array. Fill the Array with the available options and then randomly choose one, like so:
var a : Array = ['first item','second item','third item','fourth item'];
var s : String = Math.floor(Math.random()*a.length);
What happens when you want to increase the chance of the ‘first item’ being selected? A simple option is to add more occurrences of ‘first item’ into the Array, as follows:
var a : Array = ['first item','first item','first item','second item','third item','fourth item'];
var s : String = Math.floor(Math.random()*a.length);
I’m not a mathematician, but in my experiments this method increases the chance of ‘first item’ being selected; yet still being completely random.

My New Years Resolution was to try and Twitter more. So far, I’ve succeeded in Twittering regularly. It is a really odd and unusual website/service – but I’m actually getting used to it. As such, I’ve decided to add ‘blogging more often’ to my New Years Resolution.
I’ve resisted the urge to use FarCry and NearCry, and have opted to simply revamp the look and feel of my WordPress.com blog. I tend to waste too much time tinkering with the code when I use open source blogging software such as BlogCFC and NearCry.
