Windows 8

Windows 8 is coming, and I wanted to say something to set people's expectations right.  I think it'll help people align their views and appreciate this new version, if they choose to upgrade.

Don't expect Windows 8 to be Windows 7 plus more shiny new stuff.  Windows 8 was never designed in the same sense that Windows 7 was actually just Windows Vista plus more polish.  If you install Windows 8 thinking to get a minor update, you will be shocked.

Windows 8 is actually a completely different beast.  Designed with different goals altogether.  It just happens to run Windows (Windows 7) applications.

But at its core, Windows 8 is a different thing.

Historically, there was a suitable analogy, Microsoft build Windows NT to be the better kernel going forward, and combined the two systems streams (95, 98, ME) and (NT, 2000) finally into the same stream from XP.  Windows 2000 was vastly different beast from Windows 95, because it was fundamentally a different system, it just happened to run the old Windows 95 apps.

Test your C#: Generic overloaded constructors

I love languages.  Here's one for a language nut.

public class Response<T> {

    private T result;
    private string error;

    public Response(T result) { this.result = result; }
    public Response(string message) { this.error = message; }

}

You can use this generic class as a wrapper for returning data.

return new Response<int>(1000);

Or to return an abnormal result

return new Response<int>("Something has gone wrong");

Question 1

The fun part then, is what happens when you have this?

var result = new Response<string>("Is this a result or an error?");

What is result

Question 2

What about this:

public class Sample
{
    public static Response<T> GetSample<T>(T arg)
    {
        return new Response<T>(arg);
    }
}

and then:

var result = Sample.GetSample("Is this an error?");

What is result

Re: Sorry dad, you'll understand, someday

This is a quick blog post, in response to Zac Gorman's excellent Magical Game Time comic.

http://magicalgametime.com/post/19718347285/ill-stop-when-ive-saved-the-world-and-fallen-in

As you play through the game Earthbound as the kid protagonist Ness, your phone would ring every few hours, and your dad would ask you if you'd like to take a break.  If you say Yes, it'd save the game and switch it off.

The comic cleverly replies as Ness: I'll stop when I've saved the world and fallen in love.  (Sorry dad, you'll understand someday).

My boy is still three, he doesn't understand about saving the world, or falling in love, yet.  I'm sure he will soon.  And here'd be my response to him:

• All dads were boys once.
  We already understood.
• So off you go, save the world.
  Go and fall in love with your girl.
• You do what you have to do.
  This is your time, we don't expect you to hold back, or stay at home.
• When you are tired from saving the world, stop by and have some hot chocolate and ice cream.
  We will always be your biggest fan.

We will return to our regular SharePoint updates soon. 

AUSPC 2012 quick update

I'm in the strange and calm interlude between day 1 and day 2 of awesomeness in the annual Australian SharePoint Conference (AUSPC) 2012.

Day 1 has been a lot of fun.  Manned the user group booth in the morning with Dan Brown.  Met many of the SharePoint guys in the community that I haven't seen for the last 6 month to a year.  Talked to a number of vendors, and attended a number of awesome sessions on the developer track.

I also got to sit on the panel answering developer questions amongst the legends like Nick Hadlee, Ishai Sagi, Brian Farnhill and Jeremy Thake

The oddest part is probably with MCA SharePoint Wayne Ewington sitting in the audience.  Every time we said something silly he'd start shaking his head and we'd all stop.  Hilarious.

Tomorrow morning, my session on Building your own custom REST Service and consuming them with jQuery AJAX is running in the developer track at 10:30am.  Hope to see everyone there.

Dummy guide to install Win 8 on VHD for Boot to VHD

Summarized from:

• http://www.hanselman.com/blog/GuideToInstallingAndBootingWindows8DeveloperPreviewOffAVHDVirtualHardDisk.aspx
• http://technet.microsoft.com/en-us/library/gg318049(WS.10).aspx

You'll need:

• http://windows.microsoft.com/en-US/windows-8/consumer-preview
• http://www.slysoft.com/en/virtual-clonedrive.html (or some way to load the ISO into a virtual DVD)
• This PowerShell script http://archive.msdn.microsoft.com/InstallWindowsImage/Release/ProjectReleases.aspx?ReleaseId=2662

Set up boot to VHD!

1. Create a VHD

Note: I make this a dynamic disk, although I allocated up to 60GB, it only uses what it needs which was about 10 GB.

Created, and attached the VHD to Y:

Load the ISO into a virtual CD drive, mine is G:

I use virtualclonedrive to load ISO - this is a free utility.

Next install the windows image into the VHD

Easiest way that worked for me is this wonderful powershell script.

Restart and you are off to go

Your PC will boot into Windows 8, which has a new happy looking boot loader.  If you feel the 30 second delay is too long, you can change the delay to 5 seconds from the boot loader options.
