This brings back fond memories of my first job at ICL West Gorton Manchester.

My first iPad application

Apple have had another $99 from me to join the developer program (in addition to the cost of buying a MacBook Pro and iPad!) so I thought that I had better make use of them.

Over the last few weeks I’ve been getting to grips with development on the Apple iPhone OS (iPod Touch / iPhone / iPad). It’s been quite a learning curve with lots of new languages, tools and frameworks to get used to: Objective-C, Xcode IDE, Inferface Builder, Cocoa Touch, Framework, UIKit etc. Fortunately there are lots of good tutorials out there and some excellent vidoes on Apple iTunes U.

At first it all seemed a bit daunting given my Microsoft C# and .NET background (although I also know C on UNIX from many years ago which makes Obective-C at bit easier). However, the more I get into this the more I realise that a lot of the design patterns such as MVC and tools are very similar. It’s just a case of different terminology for the same thing.

Using the tutorials I have managed to get a simple Objective-C based “Hello World” application running the hard way on my iPad. The reason I say the hard way is because I have also discovered MonoTouch (http://monotouch.net/).

“MonoTouch allows developers to create C# and .NET based applications that run on Apple’s iPhone and Apple’s iPod Touch devices, while taking advantage of the iPhone APIs and reusing both code and libraries that have been built for .NET, as well as existing skills.”

I have also been able to get a MonoTouch based GPS application running on my iPad as well. Given that my application is pretty simple it is too early to say whether I am going to splash out another $399 to license MonoTouch and use the associated MonoDevelop IDE as my primarly iPhone OS development tool. It also depends on how the iPhone Developer Program License Agreement pans out in OS 4 aka the Apple v Adobe war.

MonoTouch is obviously a lot more familiar and allows me to re-use existing C# code that I have in my toolbox. Also, with MonoTouch I don’t need to worry as much about memory management e.g. retain / release and the autorelease pool.

Regardless of whether I use Objective-C or Mono / C# I still need to learn Interface Builder (IB) so this is where I will focus my learning for now.

Still a long long way to get towards my full first “proper” application but at least I have made a start.

Why are things never easy?

After my success in setting up a blog site hosted by Heart Internet (http://www.heartinternet.co.uk/) I thought that I would look into some blog clients.

My first post was made using BlogDesk (www.blogdesk.org) and worked a treat. I then did some Googles and thought that I would try Windows Live Writer (http://windowslivewriter.spaces.live.com/). Then the problems started …

After more Google time I thought that I had the found problem related to using WordPress MU and the solution here (http://mu.wordpress.org/forums/topic/14046).

#Redirect non-www to www except for Windows Live Writer requests
RewriteCond %{HTTP_HOST} ^genesysguru.com/blog
RewriteCond %{REQUEST_URI} !xmlrpc.php$
RewriteCond %{REQUEST_URI} !wlwmanifest.xml$
RewriteRule (.*) http://www.genesysguru.com/blog/$1 [R=301,L]

No joy. After various changes with and without /blog still no joy. Broke the standard pages in the process. Now starting to think that the problem relates to wlwmanifest.xml which WLW looks for or maybe I should read the documentation – but that will have to wait for another day.

As a thought, what did we ever do before Google?
