After mucking around with my webserver and switching from Apache to nginx, it appears as though my blog was offline for a month or so. I’m sure the world didn’t miss it with my amazing post frequency.

I’ve been pretty quiet on the blog recently, but very busy elsewhere. At Idea 11 we have released a new white paper on implementing Citrix XenApp. Check it out if interested.

After much planning, work and rework, the Idea 11 website is now online at http://www.idea11.com.au. Click and enjoy!

A video of my talk from Ignite Brisbane is online. Watch it here.

Ignite is a short presentation format where you have 5 minutes to talk on a topic, with 20 slides that auto-advance every 15 seconds. It’s fun, interesting – and not to mention a very different presentation format to the 30 – 60 minute talks I’ve done previously.

There are far too many guides on the net about running multiple versions of IE on the same machine. And most of them are a pain in the ass to set up.

Here’s something I bumped into today: Spoon’s Browser Sandbox. Spoon have a plugin that can launch all sorts of applications from your browser. It streams virtualised application packages to your PC through the browser. A couple of clicks and IE6 – or any other application they have in their portal – will launch.

This is probably the single best use of application virtualisation that I’ve seen in the wild. It’s the kind of “just works” technology I love. Great for web developers or occasional hacks (I’m in the latter category).

And just for the hell of it – here is a screenshot of Firefox (running natively), IE8 (running in a Windows VM via VMware Fusion) and IE6 (running in the VM with Spoon) all on my MacBook Pro:

I download and play with a fair amount of iPhone applications, but I only stick with a few in the long run. The few that I use all the time are NetNewsWire, RunKeeper Pro, and Pocket Weather AU. I’ve found a new application for that list – Instapaper.

The idea behind Instapaper is to mark web pages when you’re at your computer so that you can read them offline on your iPhone when you might have a few minutes to kill. You add a “Read Later” link – which Instapaper supplies – to bookmarks toolbar in your browser. Whenever you’re at a page that you’d like to save to read later you hit the “Read Later” bookmark. Instapaper then saves that page to your reading list.

When you’re away from your computer, run the Instapaper app on your iPhone and Instapaper grabs your reading list and formats it nicely to read on the iPhone. Pick an article and start reading. If you’re interrupted Instapaper will remember your place. Nice little touches like that make it a pleasure to use.

It’s a simple concept that is done very well. The whole process just gets out of the way and lets you do what you wanted to – read.

To IT engineers: Please, please, PLEASE stop overengineering environments that don’t need to be so complex.

Before you create a dozen 40GB LUNs for VMware RDMs for “performance” on a 60 user site, before you change the default Citrix XML port because you think it will make it easier to track the traffic, before you tweak and change every setting – please stop and think: “Does this have any additional benefit or am I doing this because I think I should?”

Hint: The answer is usually no, it doesn’t have any additional benefit. So don’t do it.

For the last two years, cloud computing has been increasing in media presence and vendor push.  Each of the major vendors in the emerging cloud space has a specific message about what cloud computing is, and what it means to you.

Whether due to cloud computing still being new, or whether it is deliberate on the part of the companies pushing it, cloud computing itself is still very loosely defined, and I’m not going to try define it here.  However, the main basis of cloud computing is paying a recurring fee for a utility computing service.

To those in the infrastructure space, cloud computing seems to be the step after virtualization – once you have virtualized your servers (to an “internal cloud”), move them to or federate with an external cloud for extra capacity.  This philosophy has been mostly generated by VMware’s vSphere marketing.

But the real benefits of cloud computing aren’t achieved with moving your existing applications (or VMs) offsite.  Let me say that in a different way – virtualization is not cloud computing, and cloud computing is not virtualization.

Your existing applications won’t scale well – they’re limited by their architecture.  They’re intertwined with the operating systems they run on.  They often won’t scale horizontally, either – many being limited to a single operating system instance for each tier. For many of them, the user interface and the way they access their data can mean that you need very high bandwidth, LAN-type latency links to your cloud provider for these applications to perform.

The true benefit of cloud computing is when the application is designed for the cloud.  This is a fundamental shift in the way that we use applications.  A cloud-based application generally doesn’t require software installation, you don’t need to think about server management, and is usually decoupled from the operating system on both the server-side and the client-side due to a web-based delivery (There are exceptions, of course).  They can be available offline with frameworks like Adobe Air and Google Gears.  They scale horizontally exceptionally well due to a stateless front-end application architecture (web servers and browsers), and a backend that can be partitioned into different databases.  Another benefit of cloud applications is that the enterprise doesn’t have to worry about application installation management – it’s all on the cloud side.

Cloud computing is here today, and you’re using it. Google.com is the archetypal cloud.  Gmail, Facebook, Twitter are all cloud applications.  Cloud computing is about bringing the scalability and resilience of the web’s best to your business application.

For those in the infrastructure space that were mystified when they did it – this is why VMware purchased SpringSource.  SpringSource is an application development framework to build cloud apps.  The next platform battle will be between the cloud frameworks – not the operating system or hypervisor. Virtualization will play a huge role, but on the back end.

Right now, the main contenders for application service cloud frameworks are: VMware/SpringSource, Microsoft Azure, (Sales)Force.com and Google App Engine.  A minor contender is Heroku – a cloud service for the excellent Ruby on Rails framework.  All of them are worth checking out.

Another year has drawn to a close, a new one has begun.  It seems to be something of a tradition that I write a short post at the end of each year.

2009 has been a big year for me.  2010 is going to be huge.

Looking back, a lot happened in 2009.  (I’ve learnt that a lot happens each year, if you sit and reflect).  In 2009 I:

• Started riding motorcycles, and got my first one
• Fought in a few Brazilian Jiu Jitsu tournaments – winning the Gold Coast championship and coming third in the open weight novice Pan Pacific championship
• Took two trips to the USA thanks to Vizioncore
• And I launched a startup – Idea 11, a specialty software and services company.  (Yes, that means I left Vizioncore).

This year, the plans are simple:

• Grow Idea 11.  Things have already started off with a bang.  This is really my number one priority.
• Focus on learning techniques in Brazilian Jiu Jitsu while getting fitter.  The focus for me is not on competition this year, although undoubtedly there will some.
• Balance – make sure I spend time with my wife, family and friends.  I have a tendency to throw all my energy and mental space at one purpose, which is great in some ways, and in others not so.  This year I will be forcing myself to take time out.  I think that not only will this be better for my relationships, but also better for long-term focus on Idea 11.

Here’s looking forward to a great 2010.  Thanks to all my friends for making the journey through life so fun and fulfilling.

If you read a few blogs, you would have noticed that over the past 12 months there has been an increased tendency to include video blog posts rather then text.

Video makes sense in certain situations – like demonstrating something, or watching hilarious motorcycle crashes.  In other situations, text is significantly better.  Why?

• I ran read over 2x faster than you can talk.
• I can skim many times faster than I can read.
• I can cut and paste useful bits from your post.
