I would like to announce the launch of a new Cloud Computing community website!

www.AllYourClouds.com

This is a new community website which focuses on having the answers for all your clouds.

Got a question about Amazon EC2, Azure, Google app engine, Go-grid, rackspace, etc? Need to know how to modify your code? Wondering how to migrate?
Just post the question and someone in the community will answer it for you.

The best part about it, is that the site uses OpenID, so there is no need to sign up. Just click to log in with your existing credentials (Google, wordpress, blogger, etc. etc.)

Highlights

• Scott Gu Rickrolls the entire PDC audience
• Silverlight 4 beta is out now!
• Silverlight can now access local resources on your computer like cameras, filesystem, drag/drop support
• Silverlight has updated WCF support
• IE9 is announced
• Work on IE9 has been going on for 3-4 weeks. Performance and Acid3 results are improving
• There will be videos on http://channel9.msdn.com/

Steve sinofsky comes on stage
Says win7 has been out for a few weeks now, it has been really humbling.
Will discuss what they learnt from Win7
Some people were saying "just fix these few things", but they knew it wasn’t just about solving problem
Their windows 7 blog was useful, there were over 6,000 comments and 10,000 emails with suggestions.
A MASSIVE part of Win7 development was how to handle just the sheer volume suggestions.
The telemetry they built into win7 helped heaps. The hardware reliability, which bits were slow or fast, was the installation of new drivers successful?
The telemetry is like a "black box recorder" of your computer
80% of customers voluntarily opt in to the telemetry feedback.
When applications crash, they send the memory dump via watson back to Microsoft to help sort out issuse.
They showed the "We Share your Pain" video the video where they shock the programmer that wrote the piece of code that is annoying you

• They had ~1,730,000 feedback reports sent back.
• ~91,500 uniqe external devices plugged in
• 14,000 unique PRINTERS plugged in
• 46,000,000 times that areo shake and snap were used
• 55% of people were using 1024×768 as the screen resolution

Talks about UAC, shows a video about it (that we can’t see via streaming due to Intellectual Property issues)
Goes back to him, he says "and when we are trying out other new features like aero snap, we do the usability testing like this" and it cuts to another video that we aren’t allowed to view.
Developing for Windows 7, what are the opportunities?
HD audio/video, new sensors, jump lists

Mike comes up on stage to talk about "new things in the ecosystem" (34 mins)
Shows an eeepc, says it came out 2 years ago. Customers were really interested in the concept.
Netbooks are now the fastest growing category of computers now
Showing a gaming PC that is liquid cooled. Showing off DirectX11
Showing a demo of 10,000 particles doing things, but it is all hardware accelerated. No CPU processing time, it is all being done on the GPU.
http://www.nvidia.com/object/directcompute.html
Showing a "Server replacement laptop". Corei7 raid5 drives, running hyperv with 3 virtual machines.
The ribbon UI feature is built into Win7 so you can use in your apps. Works well with touch
Showing how firefox supports taskbar preview, google chrome supports jump lists (he comments how he changed the default start page to to bing)

Back to just sinofsky (45 mins)
When they were building win7, they wanted to know what is it like to build a new piece of hardware? Trying to understand the flow
They decided to build their own laptop from scratch to test it out. Made a tablet pc with all the cool specs, to see how it all hangs together.
Took them about 3months to put it all together.
They announce it as the "windows 7 PDC laptop", they are giving one to each of the attendees

Internet explorer (48 mins)
I want to talk about four things, show you where we are heading.
They learnt about "responsible engineering, trustworthy experience, real world interop, innovate technologies.
One of the most talked about and liked features is around privacy and trustworthiness
Said that they made a lot of advances around incorporating web standards…
Want to continue to make sure that IE is the best featured web browser on windows.
They are working on IE9.
Standards. Admit that they need to do more around Acid3 test. Want to "be responsible" when looking at new things like HTML5
Talking about the "ACID score", in IE8 they were at 20/100, in IE9 today they are at 32/100
(in comparison, FF is at 70+ and opera is at 100)
Show graphs that there is a lot of work that goes into getting a page on your screen, different sites spend different amout of time in the subsystems (scripts, rendering, etc.)
Show a graph of performance. IE6 was far away. IE8 was still much slower than FF, chrome, etc.
IE9 now is at about the same speed as all the other browsers now.
And these are early builds of IE9 , they have only just started work on IE9 engine for 3-5 weeks
The text rending engine will take advantage of all the clear text technologies, makes it clearer than just straight GDI in IE today
Showing a demo of bing maps. Using GDI rendering they were getting ~13fps. They made the rendering engine now hardware accelerated (as in the screen rendering) and it sped up heaps.
No roadmap for IE9 yet
There will be videos on Channl9 today on IE9

Scott Guthrie comes on stage to talk about Silverlight (1:03)
In silverlight 3 then enabled hardware accelerated video rendering
They shipped blend 3 with sketchflow
Shows a video about rapid prototyping with sketchflow
A bunch of sites have used steaming (mostly sporting websites) in HD
Lots of big name companies are using it to create scientific apps, line of business apps.
Last year they were at 33% penetration, today there are on 45% of internet connected desktops.

Announcing Silverlight 4

• Focusing on 3 things
• Media
• Business apps
• Beyond the browser

• Can access webcam & microphone now
• Supporting DRM now… For some reason that feature didn’t get any applause

Demoing the new webcam stuff.
Can apply pixel shaders over the webcam feed. All the usual distortion effects. They are super fast!
Scott Gu took a random photo and then updated his twitter profile pic as it.
You can get the raw feed of the webcam feed, so they show barcode reading. He scans a copy of the barcode of his ASP.Net MVC book, then it looked it up on Amazon.
Demoing smooth streaming
Demoing other video effects, you can do slow motion, and a few others
Announcing Silverlight media (pack?) that you can use to do those effects
Smooth steaming is available on browsers that don’t have plugins (like iPhone), they enable HTTP streaming and they pick it up
http://www.iis.net/iphone

New Silverlight4 features

• Programmatic printing support
• Clipboard access
• Right click
• Mouse wheel
• Implicit styling
• Drag/drop files into silverlight

Shows an app that has English test, arabic, japanese.
Can right click in the app to bring up a context menu.
Copies the text
Pastes in a datagrid control from excel into the silverlight textbox
He drags a word doc from the desktop onto the silverlight app, the app put all the text from the document into the textbox.
He clicks print and the print dialog comes up.
Shows a Silverlight app that has a HTML control, so he has his app with bing.com in a control.
Because it is still a normal control, you can do all the normal crazy things you can do with controls, he makes the control go all about the place, he makes the bing page split up into a jigsaw puzzle and the pieces scatter around the screen.
All the usual plugins work
So he brings up youtube.com and rickrolls everyone
While the video is playing, he makes it into a puzzle again, the video is still playing in all the scattered pieces

Scott Hanselman comes on stage to demo how do develop in it (1:30)
His demo is here http://jeffhandley.com/archive/2009/11/18/contososales.aspx
Buliding a RIA services silverlight app inside VS2010
He is using an EDMX data model
Data model has many Stores have many Contacts (so has a join table)
Creates a new Contact Service
All the WCF methods are returning Iqueryable
New xaml page
The data sources window shows his service
He drags it onto his silverlight window and it auto creates a datagrid and binds it.
The Datasources window works as usual, can see all the fields, can set the control type, drag out. Can make them a ListBox
He is using implicit styling so the ListBoxes look good by default.
He can right click controls and tell them to dock fill
He clicks his control, in the properties window there is a new "styles browser"
Dragging on data pagers
The service is saying that one of the data properties is a URL, so scott changes the control to image, drags it onto the page.
Camel case intellisense support (like resharper)
Brings up the data model, shows annotations. Can now enforce rules on the data which are client side and server side validated automatically (like age must be >18)

Rep from Snapflow comes on stage (1:38)
Wants people to be able to create applications without "writing a line of code"
Well actually no, this is a "business logic" mapper.
Workflow foundation on steroids?
Yep it isn’t anywhere near as sophisticated as he claims it is, just a silverlight based workflow creator.

Just scott on stage (1:42)

New Silverlight 4 Out Of Browser features

• Windowing APIs

• Notification popups

• HTML support

• Drop target

You can say that this application MUST run in elevated mode, if the user grants it then you get

• Custom window chrome
• Can access local file system
• Cross site network
• Keyboard in full screen mode

• Hardware device access

• COM automation support

If you had office installed, you could now query outlook for your calendar from silverlight

Access the Win7 sensor information

• 30% faster startup

• New profiling support! I’m looking forward to this one

Brial Goldfarb on stage (1:47)
Showing a Silverlight 4 trusted application for accessing Facebook
So he has a custom chrome
Can programmatically move the window around the screen because of this, can make it go into "mini mode"
He uses COM automation, brings in his outlook calendar into silverlight.
Reads his friends feeds, can see the embedded videos in his feeds, can play the youtube vids in his app.
Wants to upload new photos, so he drag and drops a bunch of photos on, he can see them in silverlight and starts tagging them
Takes a photo, plugs the camera in. The app pops up a notification that camera was plugged in, and brings in the new photo.
Will be shipped as a reference sample

Just scott (1:56)
You can vote on the next silverlight features using their website.
When is silverlight4 coming out?
Beta: SL4 beta is now available for download
Final release: first half 2010

Day1 is on Azure and backend services
Day2 is on client side, Win7, IE9 and Silverlight

The keynote can be downloaded from http://microsoftpdc.com/Sessions/KEY01

Highlights of today
• Windows Azure can now have apache, tomcat and others installed
• You can have full control of your instances, install what you want on it, then set that as your new baseline to deploy apps to
• App fabric is a new add-on for Windows Server. Lets you deploy applications to your servers easier. Also lets you easily deploy to either on premise or Azure
• Dallas CTP announce. Is a way of exposing your data feeds in an easily discoverable and consumable way http://www.microsoft.com/windowsazure/dallas/

Ray ozzie walks on stage
Ray ozzie talks about how Microsoft has been talking about Software + services for the last 4 years, last year they announced Azure.
Goes on about how everything we have is "connected", PC’s, devices, etc.
They want to go towards "seamless multi screen experiences, their "3 screens & a cloud" strategy
The 3 screens are: Mobile, PC and your TV
Today we will hear more about the backend stuff. The services, azure, etc.
Tomorrow, we will hear more about front end stuff.

Software on their "3 screens and a cloud"
In tools, they have visual studio for devs. And expression studio for web
For the "3 screens"(mobile, pc, TC), they have IE + Silverlight.

Silverlight "compliments" javascript by creating highly responsive web controls
Because silverlight is .net it is the premier runtime to develop all of this software


Guy who wrote the seesmic twitter application comes on stage
Talks about how they subscribe to the "3 screens and a cloud" concept. You should be able to get your data from wherever.
They decided to write a version of seesmic using silverlight.
He is showing it using the Silverlight OOB (Out of box) experience.
They are releasing the new version today. *Edit* I installed the windows desktop version, and it is a slow non-silverlight app. Don’t know what happened here
He is saying it is very fast on Silverlight, and showing the scroll speed, etc. It does seem smoother than the bit of jerking i get when i scroll in the Adobe air version.
New features, you can click drag users between groups.
They want seesmic to be THE twitter platform. You can now create plugins for it that do lots of things. Auto tweet people, ask Mr. Tweet for more info about a person, etc.

Ray ozzie comes back
Says that tomorrow Scott Guthrie will talk about IE9. Sinofsky is talking about Silverlight 4
Starts giving the Azure marketing pitch. Made it powerful enough to scale due to all of their backend, yet familiar enough for current visual studio developers to pick it up.
The live stream glitches, then he comes back and is saying how Systems centre allows for seamless control of private clouds, etc.

Azure goes live January 1st. For all of Jan it will be free, will start charging Feb 1st.
New features that are "going live today" in Azure:

• You now have single sign on for Azure portal, Sql Azure
• They offer multiple sized VMs now (see my blog post)
• They now support much more complex service architecture (multiple worker roles, web roles)
• Support for FastCGI (PHP)
• Java running on top of Tomcat

  The Azure CDN datacentres are coming online
  Azures datacentres are built using the "modular container" design. So they can just quickly scale up datacentres. Photos of the Azure container are at http://allyourclouds.stackexchange.com/questions/5/what-do-cloud-computing-data-centers-look-like/7#7

New storage type: Azure xdrive are Azure storage blobs that are accessible using NTFS
SQL Azure It isn’t just sql server that is in VMs that are turned on.
It is a "True database as a service"
You can simply create a new database when you need it.
Don’t need to think about memory, don’t need to worry about replication, data recovery.
It works unmodified against Excel, .net. Is just a connection string.
Although Azure goes into production on Jan, they have allowed a few companies to go into production today. One of them is wordpress!

Founder of wordpress comes on stage
One of his devs at wordpress rang him and said "hey wordpress now supports PHP, mysql, sqlserver"
He logs onto the Azure portal and shows how he has an instance running apache. He only has 1 at the moment, says "what if we get slashdotted? Easy we just scale it up from here"
Says how the 2 most popular wordpress blogs are a "political one" and ICANHAZCHEEZBURGER

ICANHAZCHEEZBURGER guy comes on stage
Shows how he runs ICANHAZCHEEZBURGER, failblog, etc.
They don’t know what is going to be popular, they have MASSIVE spikes in users due to a picture suddenly becoming popular.
They really need a way to quickly scale up and down. They don’t want to have to pay during the quiet times.
Announcing a new website www.Oddlyspecific.com
They are using SQL Azure as the backend, and SQL storage for the blobs.
They have a plugin for wordpress which lets you use the Windows Azure storage platform
Means users now have more storage AND it is served over the Azure CDN!

Ray Ozzie comes back on stage
"having reliable to high scale elastic computer utility is really important"
during the windows Azure CTP, many people asked "how can I use Azure to help build my business?"

Announcing "Microsoft pinpoint"
http://www.pinpoint.com/en-US/Dallas
People wanted an easier way to find things that have already been built so that they can take advantage of it. Here you can search for solutions that already exist, experts, data feeds.
Pinpoint is integrated into the Azure portal
The most powerful place to be if you are trying to bring your services to IT pros
Online catalogues and marketplaces are useful

Announcing CTP of "Dallas" which Ray "believes to be game changing"
http://blogs.msdn.com/dallas/default.aspx
Uniform discovery way of finding data, of uniformly joining it.
Enables an open catalog and marketplace of data.
Believes it will bring in a whole new wave of "remixing"

David campbell comes on stage
Dallas lowers the barrier to finding, exploring and consuming data
Pinpoint is the place where you will find dallas data feeds.
Some are public data sources, some are commercial.
There may be ratings and reviews from people about the data

He logs in and shows how he has subscribed to 2 data feeds, one from NASA and infoUSA
Shows the full list of citysearch.com, US government
Clicks into the InfoUSA datafeed.
The data has already been described, so he can see the parameters he can put into the webform to query it (zip code, etc).
Can see the feed in Atom Pub
Clicks "analyse" and it opens up excel so he can start twisting the data.
Opens NASA feed
He can search for image scientific information, or just get the single image.
He clicks one button, and it generates a C# partial class so he can just consume it right in code!
Has a blank WPF application, he click drags a listbox on, pastes in a codesnippet to consume the data.
Shows an demo app that someone else had already written.
Is a WPF app that consumes the NASA feed and displays all the images, slideshow. Show the images using old school red/green 3D. Tells the crowd to put their 3D glasses on.
This is just a demo of what you could do if data was this easy to explore, discover and consume

Ray comes back on stage and starts a live feed with Washington DC government
Decide to democratise data
They announced health data, and encouraged everyone to use it and lots of innovation happened.
The military did the same thing, and now we have super cheap GPS. It is a great example of what can happen when data is made public.
They need to look out of the 4 walls of government and look for innovation.
http://beamartian.jpl.nasa.gov/welcome
They started off with 47 datasets. Now they have over 100,000 released datasets. Of environment hazards, of flight paths.
This data is part of the Data.gov platform
Showing an iPhone app called "career finder", shows all the government jobs available near you. App was created in only a few days
He made sure to call it a "mobile device" and not iPhone
They have a bucketload of datacentres now. The CIOs are now focused on serving up new data.
For the 1st time now, they can now focus on "service delivery" instead of worrying about infrastructure.

Live interview stops, back to Ray
When thinking of client, bet on Windows 7
When thinking of the backend, bet on Windows Azure
Think of how Pinpoint and Dallas are going to change the world with just the volume of new consumable data.
Weave together public domain data with your own data to create cool things
Shows a small vidclip.
Has "the cloud" talking about his identity crisis. He has been called a private cloud, a public cloud, he is so confused.
"YOU ARE CLOUD, embrace who you are" "embrace who you are".
WTF this is stupid.

Bob muglia comes on stage (president of server & tools)
The cloud is more than just about infrastructure
It is also about an application model. That is what he is going to talk about.
There is a lot of consistency about how they are talking about the cloud
As attributes "scale and elastic"
As things it provides "software, app platform, services"

Talks about how Bing created a controller called "auto pilot" to run all of their computers in their data centre. Automatically brought up servers to replace dead PCs



What they did was good, but it was very specific, it wasn’t generalised enough to use on their other services. It was kind of a precursor to Azure.
*blah blah, the cloud is good, lets us have resources that work together. Can have ways to deploy, etc. Recaps the cloud for 5mins* Not just me, lots of people online saying "WTF is he actually talking about"
Mentions now how we can describe architecture of a cloud app which you can use to model it. Model driven approach is better.
*waffles on for another few mins*
"take steps to make your application always on, instead of down for maintenance times"

Don Box comes on stage
Last year we showed you Azure
Since then people have said that they want to use Azure to write PHP code, Java, C++
Brings up C++ in visual studio
They are going to write a CGI app, grab the query string and process it.
They are going to use pointers all over the place.
So when they hit the web app, they are going to show the 4 bytes before the query string.
Points out how there is a bug, so he puts in an asm push and pop command
They have a 2nd project, an Azure cloud project, so they are pushing it up into Azure now
Goes into the portal and publishes the Azure app ready
Moves to SQL Azure
Last year they accessed SQL Azure using REST.
Feedback was "yeah REST is great…. But we are used to connection strings and transactions and T-Sql"
They create a new SQL Azure database, now they are going to use SQL Server management studio to connect to it.
They open it up, and start executing T-SQL against it.
creates a table, starts a transaction, pastes in all the rows to insert, ends transaction
Hits execute and it immediately runs against the cloud
Last year talked about Access control Service
Enterprise grade authorisation
Feedback was "we like that… But we want something more lightweight so we can use in web pages, etc"
Worked with google, etc. To come up with a way to do it.
They use http://en.wikipedia.org/wiki/OAuth
Try to hit the data from javascript. Nope can’t get in because they aren’t authrorised.
So in javascript, they request a token, and can then get into it.

Kelly blue book comes on stage
They have 2 data centres, try to get one data centre serving all the customers, so they have a 2nd failover data centre.
They were paying lots for servers they didn’t need… So *surprise* they moved it to Azure to reduce costs since they can elastically scale up and down.
Their data goes through ETL’s and other processes, they can still use the exact same process with SQL Azure
Demoing SQL Azure Data Sync.
They can keep their on premise SQL server and the Azure one in sync. Using Azure as a backup for spikes
They have taken the time down to provision a new server down from 6 weeks to 6mins with Azure

Back to just Bob mulgia, he shows a demo reel
Dominos pizza, they have a MASSIVE spike during superbowls which is expensive to provision for.
Seiemens talking about hybrid clouds. Their on premise data centre combined with offloading to Azure

Back to bob. (1Hour, 30mins)



Access Control System is an important way of saying who has access to your services.
Sometimes you want low level access.

Announcing "project Sydney", available next year
Allows you to connect your existing apps running on your servers with Windows Azure.
Demo of it with one of their apps
They have a charity promotion called "give" which is a charity auction.
Showing it running in the IT datacentre at Microsoft (even if his URL says localhost….)
From Azure, they try to tell it to connect to his SQL server that is running on premises.
He uses the Windows Azure connectivity Agent (project Sydney) to allow "the cloud" to connect to their on premise SQL server.
Now Azure can scale and do all the compute while connecting to their existing data.

New windows Azure virtual machine role

1. Select windws server base image
1. Customised virtual machine role
2. Snapshot virtual machine image
3. Deploy app and target your new VM role

So you can preload Apache on it or whatever you want.
You can remote desktop onto it to configure it.

Announcing Windows "app fabric" (I THINK this is dublin)
Allows you to create highly scalable flexible app platform.
Built on IIS, WCF, workflow, etc. Data caching
Is an add-in for windows server
You can zip up your application, so it can be passed to your IT admins and they can publish it straight into staging. Could also send to your internet hosts and get them to deploy it. Sounds like an easier way to deploy ASP.Net applications
Windows Azure will use it, will allow for the ease of deployment between Azure and your on premise data centres.

Explanation from Mary Jo Foley: The AppFabric technology combines hosting and caching technologies (formerly known as Microsoft code-named "Dublin" and Microsoft code-named "Velocity") with the Windows Azure platform AppFabric Service Bus and AppFabric Access Control (formerly referred to as .NET Services).



New person on stage demonstrating new features in Visual studio 2010
Demoing new Visual studio 2010 features.
He runs the application, does a few things then closes it.
It shows the call trace of his app so he can see how it works (then he drags the tab to his 2nd monitor and ppl go crazy)
Showing windows federated identity. (Geneva)
AD now has an STS provider in it.
Shows how to get your app to run with authentication by just right click your solution in visual studio and using the wizard (just like adding a WCF reference)
Says his app is running slower than it should be, hitting the DB too much? So he clicks "break all" and intellisense comes up.
Filters just to show the calls to ADO.Net, then he can drill down and see where the calls were made.

Douglas purdy (Data modeling group) comes on stage (2 hours)
Opens up visual studio and an exisiting ASP.Net MVC app, windows identity services
Is going to migrate it to Azure using "models"
In VS he Creates -> New project -> application model project
Shows a blank workspace with a toolbox.
Can see "the web role", "the worker role", "the database" + more in the toolbox
To deploy the application he is going to drag out 3 roles onto the workspace
-Web role
-App fabric
-And database

Then drags the projects on top of the icons he has there for web role, database.
Can say how many instances of each he wants
He wants to just push it out into the cloud now.
Right click, "publish to test environment"
They are shredding it into oslo data modeling (which has been renamed to SQL server data modeling?)
Windows identity services is now just working, still hitting the on premise Active Directory.
Right click, generates app package.
Bundles it up into a single package. Myproject.app on the desktop
So to push it out into production, he opens up powershell
He can run "deploy-application myproject.app https://myserver -whatif"
The whatif will show what will change if he does the deployment. How many instances of each thing.
Shows Microsoft operations manager, shows it connected to Windows Azure
Can see a diagram of the application that was put into SQL server data modeling inside of operations manager. Can see the load in each of the servers for each of those roles in the diagram
They can see that the server in Azure is overloaded, so they tell it to scale up from 2 to 4 from inside Operations manager.
They expand that web role for the ASP.net app, they can see the 2 existing servers and the 2 that are spinning up.

Bob back on stage

Says "see, this is why i was talking about the importance of modelling".
talks about how all of this is in the new server / services stack.
Keynote closes

*Update* Microsoft have updated their FAQ with instance pricing

In my previous post on the newly released Azure SDK I touched on the ability to set a size for your VM instance.

Lets delve down into what size virtual machines are available (values from http://msdn.microsoft.com/en-us/library/ee814754.aspx)

The sizes are easy to follow, they are all just multiples of the base VM size. Microsoft have said in their FAQ that the pricing is based on multiples of the small VM size. It is based on “CPU cores / hour”, so $0.12 per hour for the small VM, $0.24 for medium, $0.48 for large, etc.

Lets draw up a matrix to compare the Microsoft Azure and Amazon EC2 pricing side by side:

Azure						Amazon EC2
CPU cores	Memory	Platform	OS	cost / hour		"Compute units"	Memory	Platform	OS	cost / hour
1	1.7 GB	64 Bit	Windows Server 2008 R2	$0.12		1	1.7 GB	32 Bit	Windows Server 2003	$0.12
2	3.5 GB	64 Bit	Windows Server 2008 R2	$0.24		N/A	N/A	N/A	N/A	N/A
4	7 GB	64 Bit	Windows Server 2008 R2	$0.48		4	7.5 GB	64 Bit	Windows Server 2003	$0.48
8	15 GB	64 Bit	Windows Server 2008 R2	$0.96		8	15 GB	64 Bit	Windows Server 2003	$0.96

(Values taken from http://msdn.microsoft.com/en-us/library/ee814754.aspx and http://aws.amazon.com/ec2/instance-types/ )

The Azure and EC2 packages are roughly equivalent to each other and the “CPU” speeds are roughly the same (Azure: 1.5-1.7GHz, EC2: 1.0-1.2GHz Xeon). Where they still do differ though is Amazon is still only offering Windows Server 2003, and the low end instance is only 32bit compared.

Conclusion

From a .Net developer’s perspective I see Azure winning here. For the same price I can get Windows server 2008 R2 over a 2003 instance, which gives me IIS7. If you are developing cutting edge .Net code (like ASP.Net MVC), IIS7 is going to be a lot easier to work with than IIS6. Of course if you need to control more in your instance then Amazon is going to offer you that over Azure.

Footnote: Amazon does have a few more instance types available that offer higher CPU processing or increased memory. Here I have just used the basic instance types for easier comparison.

*Update* I have posted some further analysis of the new Azure instance sizes in a new post – Analysis of windows azure virtual machine sizes

With more details on Windows Azure to be announced next week at PDC, Microsoft have released the latest version of the Azure tools & SDK in preparation. There are a few things we can learn from them.

http://blogs.msdn.com/cloud/archive/2009/11/12/windows-azure-tools-and-sdk-v1-0-november-2009-release.aspx

As this has been marked as version 1.0 of the SDK, I think we can safely assume that this release of the tools can be seen as “Feature complete”, especially with Azure to be officially released soon. So although we may not see any tool refreshes in the coming months, there is sure to be newer version of the tools for the upcoming versions of VS2010

There are some interesting update notes that jump out at me

“The sample storage client has been replaced by a new production quality library” – This is great to see as most people use this as production code anyway, despite Microsoft trying to say “it is an example of how you may do it yourself”

“Service Model UI: A redesigned and significantly more complete interface for manipulating Role configuration information. To access, double-click on a role node in the Solution Explorer” – This feature is quite nice, we don’t need to manually edit the .cscfg file, we have a nice UI to change it instead.

“Ability to choose the size of the VM for a role instance” – Microsoft has previously stated that we will eventually have “more control” of the VM instances, but this sounds interesting. You can find about these VM sizes at this url http://msdn.microsoft.com/en-us/library/ee814754.aspx. They differ in CPU counts and RAM. Perhaps there is some new pricing to be announced at PDC based around this?

But this is what I have been hanging out for! “Service Runtime library updated to support inter-role communication and notification of configuration changes” – I have a bunch of research ideas that required this feature. Queues are great for structured sequential data and is the way you should be processing data between instances. But for things like network rendering you really needed this feature.

This year I was able to present at Code Camp! In my mind, Code Camp is meant to be an event where you try and to whacky things with code. So I decided to explore what the possibilities were of using Windows Azure to create Artificial life in the cloud. I ended up focusing more on the possibilities of farming out the work of calculating genetic algorithms to find optimal paths for the travelling salesman problem.

The first section gives a background on cloud computing and Windows Azure. If you are interested in an overview of Azure i recommend you watch my Remix presentation on Windows Azure instead, as I did it after this talk and had a chance to refine that section further.

The talk went well, unfortunately the video capture software I was using was eating up one of my cores on my dual core laptop which meant the calculations ran slower than they should have. I apologise for the audio quality also, I didn’t have the drivers for my laptop microphone so ended up having to use my mobile phone to record the audio.

I hope you enjoy my talk!

I just successfully upgraded my HTC Touch Dual (known as NIKE in other regions) from windows mobile 6.0 to 6.5. It took me the better part of 6 hours to fully research and figure out how to do it. So to help the next person out, here is how to do it (entire process will take about 20minutes)

Note: This is the process of updating a HTC Touch dual. Updating other phone models is very similar. Just find your specific version of Soft SPL, Hard SPL & ROM images. Go to http://forum.xda-developers.com to find your model phone.

BIG WARNING: You will need WinXP to do this. IT DOES NOT WORK WITH VISTA OF WIN7. I wasted 5 hours at this point when i bricked my mobile because it will not flash correctly. So find an old WinXP machine just while you are doing this. Also you may want to backup all your existing data. I take no responsibility if you brick your phone.

Step 1. Update the boot loader

The boot loader that is on all mobile phones says what roms are valid for it. Because we are going to be flashing a non-official ROM onto it, we need to replace it. The way to do this is to run a “Soft SPL”, which will temporarily allow you to flash a new bootloader onto your phone (called a Hard SPL).

a) Download the soft SPL onto your phone and run it

go to this forum post http://forum.xda-developers.com/showthread.php?t=355730 and download sspl-1.16-nike.zip.

Read this the first forum post to give you an idea of what we are doing. Copy sspl-1.16-nike.exe to your phone and run it. You will now see a temporary bootloader which will allow you to upgrade your phone’s bootloader. Make sure you have removed your SIM card, SD cards, etc.

b) Unplug/replug the USB

My computer wouldn’t detect the phone until I did this. The boot loader should say USB after you’ve done it.

c) Download the hard SPL (new boot loader)

in the same forum thread http://forum.xda-developers.com/showpost.php?p=2786065&postcount=439, download hardspl-1.22-nike-shipped.zip

On your computer run ROMUpdateUtility.exe. It should step you through updating your bootloader.

Step 2. Updating your windows mobile ROM

This is where you have fun trying to find a custom ROM that has been tweaked for your model phone. I just went with the most recently updated version for my phone

a) Download the ROM

Windows mobile 6.5 ROM for HTC Touch dual  http://forum.xda-developers.com/showthread.php?t=534205

b) Turn your phone off, and start it up in the boot loader

All phones are different in how they do this. For the HTC it was a matter of holding the camera button while i turned it on

c) run the updater on your PC

This is exactly the same as how we updated the Hard SPL. Once in the boot loader, plug the USB cable in so that the phone says USB. Then run CustomRUU.exe and step through the wizard.

Step 3. Updating your Radio ROM

After you have updated the version of windows mobile on your phone, you will most likely have to update the Radio ROM on your device also. Strange things happen like the camera not working, the phone freezing when you make a call, etc. The phone has an entirely separate linux engine running the phone functions, windows mobile just hooks into it to invoke making a call, doing data connections, etc.

a) find a Radio ROM for your phone

Here are the ones for HTC touch dual http://forum.xda-developers.com/showthread.php?t=369502

I went with the latest version that said “highly recommended” next to it.

b) flash it onto your phone the same way you did the windows mobile ROM

Step 4. Enjoy

That is it!

HELP! my phone is bricked

If you do happen to brick your phone, and it is stuck at the boot loader, this may help. It saved my phone when it got stuck at the boot loader http://forum.xda-developers.com/showthread.php?t=371154

The March 2009 release of the Virtual Earth control for Silverlight (now known as the bing map control) was a great release. Up until then, projects like Deep Earth were trying to provide us with a way to use deep zoom + the virtual earth tiling to allow us to build Silverlight apps. Now Microsoft have given us an official control to play with.

One of the big downsides of the official control was the lack of databinding. You still had to add / remove your pushpins & shapes manually just like you would with the AJAX version. There is code available on the Microsoft website that adds dependency properties to the Bing Maps control which expose ItemsCollection, ready for you to databind to. If you combine this with some custom datatemplates, you are able to databind directly to the map as you would expect.

Step 1. Install the Bing Maps control

The CTP of the control is available from Microsoft connect https://connect.microsoft.com/silverlightmapcontrolctp

Step 2. Download the databinding enabler

You just need to download this single .cs file and include it in your project http://code.msdn.microsoft.com/VESLBindingProps

Step 3. Add the Bing maps control to your .xaml page

Add the virtual earth namespace for the control, the ve namespace for the dependency properties, and then the grid. It should look something like this

<UserControl x:Class="SDDNTestRun.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:VirtualEarth="clr-namespace:Microsoft.VirtualEarth.MapControl;assembly=Microsoft.VirtualEarth.MapControl"
    xmlns:ve="clr-namespace:Synergist.VE"
    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
    <Grid x:Name="LayoutRoot" >
        <VirtualEarth:Map x:Name="MyMap"
                CopyrightVisibility="Collapsed" LogoVisibility="Collapsed" Mode="Aerial">
        </VirtualEarth:Map>
    </Grid>
</UserControl>

Step 4. Add the data template for shapes and the map layer

This data template to databind polyshapes is fairly easy. You just need to set the polyshape style (thickness, colour, etc.) and then databind the points to the locations collection

<DataTemplate x:Key="MapShape">
    <VirtualEarth:MapPolygon Fill="Orange" Stroke="Green" StrokeThickness="2" Opacity="0.4" Locations="{Binding}" />
</DataTemplate>

And here is how you add the layer to the map

<VirtualEarth:Map x:Name="MyMap"
    CopyrightVisibility="Collapsed" LogoVisibility="Collapsed" Mode="Aerial">
    <VirtualEarth:MapLayer x:Name="ShapeLayer"
        ve:Properties.ItemsSource="{Binding}"
        ve:Properties.ItemTemplate="{StaticResource MapShape}" />
</VirtualEarth:Map>

Step 5. Add some data to the layer

This is the fun bit, figure out what the coordinates for your shape are and create a collection for it. Myself, i’m going to use the site of the Microsoft office here in Melbourne. I’m just going to do this in the page constructor in the code behind

MyMap.Center = new Location(-37.8222600730785, 144.962552763317);
MyMap.ZoomLevel = 17;

var shapeList = new ObservableCollection<LocationCollection>
{
new LocationCollection
    {
        new Location(-37.8217176782418, 144.961662269924),
        new Location(-37.8214041044085, 144.962391830776),
        new Location(-37.8222346484096, 144.963314510677),
        new Location(-37.8228194135791, 144.962638594005),
        new Location(-37.8223617716666, 144.961887575481),
        new Location(-37.8220397256568, 144.962005592678),
    }
};
ShapeLayer.DataContext = shapeList;

Step 6. Hit run and see your databinding in action!

Because we are databinding to an observable list, we can just add new items to it and watch the new shapes appear. It is also possible to add extra points to an existing shape, and see it update live on the map.

If you want to add an extra shape, add this to a click event to see the databinding happening interactively

shapeLists.Add(new LocationCollection()
{
    new Location(-37.8207645163828, 144.961630711604),
    new Location(-37.8200356576319, 144.96164144044),
    new Location(-37.8197136014726, 144.96321857934),
    new Location(-37.8206882408042, 144.962092051554)
});

Step 7. Pushpins

Pushpins are a little more involved. Here i have created a “Point of Interest” class, that has the location and extra details. Here i’m just going to use the location property to databind to. The good thing is that you can use any control as your pushpin. In the included sample my PushPin control expands out when you hover, and collapses when you move off it.

<DataTemplate x:Key="MicrosoftPushPin">
    <Controls:PushPin VirtualEarth:MapLayer.MapPosition="{Binding Loc}"
        VirtualEarth:MapLayer.MapPositionMethod="Center"  />
</DataTemplate>

public class POI
{
    public string Loc { get; set; }
    public string Description { get; set; }
}

//In the class constructor
PushPinLayer.DataContext = new ObservableCollection<POI>
{
   new POI() { Loc = "-37.8222600730785, 144.962552763317" }
};

Sample app

In case you just want to see it working, I’ve included the demo I built live at the Melbourne Silverlight Desiginer & Developer Network. Good luck!

There has been a lot of discussions over the new Google Chrome OS announcement lately. I just read this article Google’s Chrome OS: Maybe Not a "PC" OS After All and this paragraph caught my attention

“The OS that would drive such a system would require a lot of work beyond just hosting a browser on Linux, which may be why Google says it is a year or more away. That’s because many of the add-ons that we need to enable web sites to properly function would need to be moved from desktop applications to become a part of the OS. I’m talking about things such as media players, codecs and add-ons that support PDF and other file formats, Adobe Flash, or even Microsoft Silverlight.  Google Gears, or whatever caching technology, also needs a lot of work."

That last sentence is what caught my eye. Now it is no secret that Google have been promoting HTML5 VERY strongly. There have been a number of articles on the web since the Google conference last month about how much they are promoting HTML5, and what their motives could be. Most of the articles come to the conclusion that in the end, will we even need plugins like flash or Silverlight.

Google have made it very clear that “for application developers, the web is the platform”, implying that you won’t be able to develop for the linux kernel it is running on top of.

If you tie Google’s push for HTML5 with the Chrome OS announcement, then maybe we are onto something. Perhaps they aren’t trying to displace windows at all, but instead increase the number of devices that support HTML5 and not Silverlight / Flash / Java. They could be aiming this announcement at web developers here. When web devs are thinking what platform they should create their new web app on, they may default to using HTML5 over Silverlight because of the additional reach HTML5 is going to give them.

So there is my angle, they aren’t targeting Microsoft at the desktop, but are instead trying to dislodge them from the web and stopping adoption of Silverlight.
