protected abstract override Foo(); – er... what?

- by Muljadi Budiman

A couple of weeks back, a co-worker was pondering a situation he was facing. He was looking at the following class hierarchy: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { } class FirstConcrete : SecondaryBase { } class SecondConcrete : SecondaryBase { } Basically, the first 2 classes are abstract classes, but the OriginalBase class has Test implemented as a virtual method. What he needed was to force concrete class implementations to provide a proper body for the Test method, but he can’t do mark the method as abstract since it is already implemented in the OriginalBase class. One way to solve this is to hide the original implementation and then force further derived classes to properly implemented another method that will replace it. The code will look like the following: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { protected sealed override void Test() { Test2(); } protected abstract void Test2(); } class FirstConcrete : SecondaryBase { // Have to override Test2 here } class SecondConcrete : SecondaryBase { // Have to override Test2 here } With the above code, SecondaryBase class will seal the Test method so it can no longer be overridden. Then it also made an abstract method Test2 available, which will force the concrete classes to override and provide the proper implementation. Calling Test will properly call the proper Test2 implementation in each respective concrete classes. I was wondering if there’s a way to tell the compiler to treat the Test method in SecondaryBase as abstract, and apparently you can, by combining the abstract and override keywords. The code looks like the following: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { protected abstract override void Test(); } class FirstConcrete : SecondaryBase { // Have to override Test here } class SecondConcrete : SecondaryBase { // Have to override Test here } The method signature makes it look a bit funky, because most people will treat the override keyword to mean you then need to provide the implementation as well, but the effect is exactly as we desired. The concepts are still valid: you’re overriding the Test method from its original implementation in the OriginalBase class, but you don’t want to implement it, rather you want to classes that derive from SecondaryBase to provide the proper implementation, so you also make it as an abstract method. I don’t think I’ve ever seen this before in the wild, so it was pretty neat to find that the compiler does support this case.

Disable touchpad tap to click on Oneiric ocelot

- by AWE

You've heard this a million times but the "tap to click" is a pain in the behind and I want to disable it. There is no touchpad in gpointing-device-settings and neither in mouse and touchpad in system settings. I've tried some commands in terminal but it's all crap. Dconf-editor doesn't react. How about solving this once and for all? xinput list: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ?

- by Miguel

I can't make work the multitouch of the ALPS touchpad in my Dell Inspiron I15RN-3647BK with Ubuntu 11.10 x64, kernel 3.0.0-17-generic... I have tried with this driver but it doesn't work http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.10/psmouse-alps-dkms_0.10_all.deb. This is the result from the following command: user@laptop:~$ xinput list ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ?

Any ideas? Thanks in advance...

- by Robik

I am using ubuntu 11.10. I want the following 3 things: I have dell inspiron 5110 laptop. There is button at the top right corner of laptop which can be used for turning the screen off. It works in windows but it does not work in ubuntu 11.10. Even in the manual of the laptop, it the button is supported only in windows. Is there a way to activate it in ubuntu 11.10? Some of the keys like: "break" etc. are missing. Can I use other keys (or combinations of other keys) to function as those missing keys? In the program, "mouse and touchpad", there is no tab for touchpad. I want to enable vertical and horizontal scrolling. How do I do that?

How can I Include Multiples Tables in my linq to entities eager loading using mvc4 C#

- by EBENEZER CURVELLO

I have 6 classes and I try to use linq to Entities to get the SiglaUF information of the last deeper table (in the view - MVC). The problem is I receive the following error: "The ObjectContext instance has been disposed and can no longer be used for operations that require a connection." The view is like that: > @model IEnumerable<DiskPizzaDelivery.Models.EnderecoCliente> > @foreach (var item in Model) { > @Html.DisplayFor(modelItem => item.CEP.Cidade.UF.SiglaUF) > } The query that i use: var cliente = context.Clientes .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); The question is: How Can I improve this query to pre loading (eager loading) "Cidade" and "UF"? See below the classes: public partial class Cliente { [Key] [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] public int IdCliente { get; set; } public string Email { get; set; } public string Senha { get; set; } public virtual ICollection<EnderecoCliente> Enderecos { get; set; } } public partial class EnderecoCliente { public int IdEndereco { get; set; } public int IdCliente { get; set; } public string CEPEndereco { get; set; } public string Numero { get; set; } public string Complemento { get; set; } public string PontoReferencia { get; set; } public virtual Cliente Cliente { get; set; } public virtual CEP CEP { get; set; } } public partial class CEP { public string CodCep { get; set; } public string Tipo_Logradouro { get; set; } public string Logradouro { get; set; } public string Bairro { get; set; } public int CodigoUF { get; set; } public int CodigoCidade { get; set; } public virtual Cidade Cidade { get; set; } } public partial class Cidade { public int CodigoCidade { get; set; } public string NomeCidade { get; set; } public int CodigoUF { get; set; } public virtual ICollection<CEP> CEPs { get; set; } public virtual UF UF { get; set; } public virtual ICollection<UF> UFs { get; set; } } public partial class UF { public int CodigoUF { get; set; } public string SiglaUF { get; set; } public string NomeUF { get; set; } public int CodigoCidadeCapital { get; set; } public virtual ICollection<Cidade> Cidades { get; set; } public virtual Cidade Cidade { get; set; } } var cliente = context.Clientes .Where(c => c.Email == email) .Where(c => c.Senha == senha) .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); Thanks!

SPARC T5-4 LDoms for RAC and WebLogic Clusters

- by Jeff Taylor-Oracle

I wanted to use two Oracle SPARC T5-4 servers to simultaneously host both Oracle RAC and a WebLogic Server Cluster. I chose to use Oracle VM Server for SPARC to create a cluster like this: There are plenty of trade offs and decisions that need to be made, for example: Rather than configuring the system by hand, you might want to use an Oracle SuperCluster T5-8 My configuration is similar to jsavit's: Availability Best Practices - Example configuring a T5-8 but I chose to ignore some of the advice. Maybe I should have included an alternate service domain, but I decided that I already had enough redundancy Both Oracle SPARC T5-4 servers were to be configured like this: Cntl 0.25 4 64GB App LDom 2.75 CPU's 44 cores 704 GB DB LDom One CPU 16 cores 256 GB The systems started with everything in the primary domain: #

NTFS Corruption: Files created in Linux corrupted when Windows Boots

- by Logan Mayfield

I'm getting some file loss and corruption on my Win7/Ubuntu 12.04 dual boot setup. I have a large shared NTFS partition. I have my Windows Docs/Music/etc. directories on that file and have the comparable directors in Linux setup as a sym. link. I'm using ntfs-3g on the linux side of things to manage the ntfs partition. The shared partition is on a logical partition along with my Linux /home / and /swap partitions. The ntfs partition is mounted at boot time via fstab with the following options: ntfs-3g users,nls=utf8,locale=en_US.UTF-8,exec,rw The problem seems to be confined to newly created and recently edited files. I have not see data loss or corruption when creating/editing files in Windows and then moving over to Ubuntu. I've been using the sync command aggressively in Ubuntu to try to ensure everything is getting written to the HDD. I do not use hibernate in Windows so I know it's not the usual missing files due to Hibernation problem. I'm not seeing any mount related issues on dmesg. Most recently I had a set of files related to a LaTeX document go bad. Some of them show up in Ubuntu but I am unable to delete them. In the GUI file browser they are given thumbnails associated with files I created on my last boot of Windows. To be more specific: I created a few png files in Windows. The files corrupted by that Windows boot are associated with running PdfLatex on a file and are not image files. However, two of the corrupted files show up with the thumbnail image of one of the previously mentioned png files. The png files are not in the same directory as the latex files but they are both win the Document Folder tree. I've had sucess with using NTFS for shared data in the past and am hoping there's some quirk here I'm missing and it's not just bad luck. On one hand this appears to be some kind of Windows problem as data loss occurs when I boot to Windows after having worked in Ubuntu for a while. However, I'm assuming it's more on the Ubuntu end as it requires the special NTFS drivers. Edit for more info: This is a Lenovo Thinkpad L430. Purchased new in the last month. So it's a fairly fresh install. Many of the files on the shared partition were copied over from a previous NTFS formatted shared partition on another HDD. As requested: here's a sample chkdsk log. Some of the files its mentioning were files that got deleted off the partition while in Ubuntu. Others were created/edited but not deleted. Checking file system on D: Volume dismounted. All opened handles to this volume are now invalid. Volume label is Files. CHKDSK is verifying files (stage 1 of 3)...

SSIS - XML Source Script

- by simonsabin

The XML Source in SSIS is great if you have a 1 to 1 mapping between entity and table. You can do more complex mapping but it becomes very messy and won't perform. What other options do you have? The challenge with XML processing is to not need a huge amount of memory. I remember using the early versions of Biztalk with loaded the whole document into memory to map from one document type to another. This was fine for small documents but was an absolute killer for large documents. You therefore need a streaming approach. For flexibility however you want to be able to generate your rows easily, and if you've ever used the XmlReader you will know its ugly code to write. That brings me on to LINQ. The is an implementation of LINQ over XML which is really nice. You can write nice LINQ queries instead of the XMLReader stuff. The downside is that by default LINQ to XML requires a whole XML document to work with. No streaming. Your code would look like this. We create an XDocument and then enumerate over a set of annoymous types we generate from our LINQ statement XDocument x = XDocument.Load("C:\\TEMP\\CustomerOrders-Attribute.xml"); foreach (var xdata in (from customer in x.Elements("OrderInterface").Elements("Customer") from order in customer.Elements("Orders").Elements("Order") select new { Account = customer.Attribute("AccountNumber").Value , OrderDate = order.Attribute("OrderDate").Value } )) { Output0Buffer.AddRow(); Output0Buffer.AccountNumber = xdata.Account; Output0Buffer.OrderDate = Convert.ToDateTime(xdata.OrderDate); } As I said the downside to this is that you are loading the whole document into memory. I did some googling and came across some helpful videos from a nice UK DPE Mike Taulty http://www.microsoft.com/uk/msdn/screencasts/screencast/289/LINQ-to-XML-Streaming-In-Large-Documents.aspx. Which show you how you can combine LINQ and the XmlReader to get a semi streaming approach. I took what he did and implemented it in SSIS. What I found odd was that when I ran it I got different numbers between using the streamed and non streamed versions. I found the cause was a little bug in Mikes code that causes the pointer in the XmlReader to progress past the start of the element and thus foreach (var xdata in (from customer in StreamReader("C:\\TEMP\\CustomerOrders-Attribute.xml","Customer") from order in customer.Elements("Orders").Elements("Order") select new { Account = customer.Attribute("AccountNumber").Value , OrderDate = order.Attribute("OrderDate").Value } )) { Output0Buffer.AddRow(); Output0Buffer.AccountNumber = xdata.Account; Output0Buffer.OrderDate = Convert.ToDateTime(xdata.OrderDate); } These look very similiar and they are the key element is the method we are calling, StreamReader. This method is what gives us streaming, what it does is return a enumerable list of elements, because of the way that LINQ works this results in the data being streamed in. static IEnumerable<XElement> StreamReader(String filename, string elementName) { using (XmlReader xr = XmlReader.Create(filename)) { xr.MoveToContent(); while (xr.Read()) //Reads the first element { while (xr.NodeType == XmlNodeType.Element && xr.Name == elementName) { XElement node = (XElement)XElement.ReadFrom(xr); yield return node; } } xr.Close(); } } This code is specifically designed to return a list of the elements with a specific name. The first Read reads the root element and then the inner while loop checks to see if the current element is the type we want. If not we do the xr.Read() again until we find the element type we want. We then use the neat function XElement.ReadFrom to read an element and all its sub elements into an XElement. This is what is returned and can be consumed by the LINQ statement. Essentially once one element has been read we need to check if we are still on the same element type and name (the inner loop) This was Mikes mistake, if we called .Read again we would advance the XmlReader beyond the start of the Element and so the ReadFrom method wouldn't work. So with the code above you can use what ever LINQ statement you like to flatten your XML into the rowsets you want. You could even have multiple outputs and generate your own surrogate keys.

AspNetCompatibility in WCF Services – easy to trip up

- by Rick Strahl

This isn’t the first time I’ve hit this particular wall: I’m creating a WCF REST service for AJAX callbacks and using the WebScriptServiceHostFactory host factory in the service: <%@ ServiceHost Language="C#" Service="WcfAjax.BasicWcfService" CodeBehind="BasicWcfService.cs" Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory" %> to avoid all configuration. Because of the Factory that creates the ASP.NET Ajax compatible format via the custom factory implementation I can then remove all of the configuration settings that typically get dumped into the web.config file. However, I do want ASP.NET compatibility so I still leave in: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> </system.serviceModel> in the web.config file. This option allows you access to the HttpContext.Current object to effectively give you access to most of the standard ASP.NET request and response features. This is not recommended as a primary practice but it can be useful in some scenarios and in backwards compatibility scenerios with ASP.NET AJAX Web Services. Now, here’s where things get funky. Assuming you have the setting in web.config, If you now declare a service like this: [ServiceContract(Namespace = "DevConnections")] #if DEBUG [ServiceBehavior(IncludeExceptionDetailInFaults = true)] #endif public class BasicWcfService (or by using an interface that defines the service contract) you’ll find that the service will not work when an AJAX call is made against it. You’ll get a 500 error and a System.ServiceModel.ServiceActivationException System error. Worse even with the IncludeExceptionDetailInFaults enabled you get absolutely no indication from WCF what the problem is. So what’s the problem? The issue is that once you specify aspNetCompatibilityEnabled=”true” in the configuration you *have to* specify the AspNetCompatibilityRequirements attribute and one of the modes that enables or at least allows for it. You need either Required or Allow: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] without it the service will simply fail without further warning. It will also fail if you set the attribute value to NotAllowed. The following also causes the service to fail as above: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.NotAllowed)] This is not totally unreasonable but it’s a difficult issue to debug especially since the configuration setting is global – if you have more than one service and one requires traditional ASP.NET access and one doesn’t then both must have the attribute specified. This is one reason why you’d want to avoid using this functionality unless absolutely necessary. WCF REST provides some basic access to some of the HTTP features after all, although what’s there is severely limited. I also wish that ServiceActivation errors would provide more error information. Getting an Activation error without further info on what actually is wrong is pretty worthless especially when it is a technicality like a mismatched configuration/attribute setting like this.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET WCF AJAX

Are CSS sprites bad for SEO?

- by UpTheCreek

Nowadays often what was accomplished with an <img> tag is now done with something like a <div> with a Css background image set using a CSS 'sprite' and an offset. I was wondering what kind of an effect his has on SEO, as effectively we lose the alt attribute (which is indexed by google), and are stuck with the 'title' attribute (which as far as I understand is not indexed). Is this a significant dissadvantage?

How to refactor a Python “god class”?

- by Zearin

Problem I’m working on a Python project whose main class is a bit “God Object”. There are so friggin’ many attributes and methods! I want to refactor the class. So Far… For the first step, I want to do something relatively simple; but when I tried the most straightforward approach, it broke some tests and existing examples. Basically, the class has a loooong list of attributes—but I can clearly look over them and think, “These 5 attributes are related…These 8 are also related…and then there’s the rest.” getattr I basically just wanted to group the related attributes into a dict-like helper class. I had a feeling __getattr__ would be ideal for the job. So I moved the attributes to a separate class, and, sure enough, __getattr__ worked its magic perfectly well… At first. But then I tried running one of the examples. The example subclass tries to set one of these attributes directly (at the class level). But since the attribute was no longer “physically located” in the parent class, I got an error saying that the attribute did not exist. @property I then read up about the @property decorator. But then I also read that it creates problems for subclasses that want to do self.x = blah when x is a property of the parent class. Desired Have all client code continue to work using self.whatever, even if the parent’s whatever property is not “physically located” in the class (or instance) itself. Group related attributes into dict-like containers. Reduce the extreme noisiness of the code in the main class. For example, I don’t simply want to change this: larry = 2 curly = 'abcd' moe = self.doh() Into this: larry = something_else('larry') curly = something_else('curly') moe = yet_another_thing.moe() …because that’s still noisy. Although that successfully makes a simply attribute into something that can manage the data, the original had 3 variables and the tweaked version still has 3 variables. However, I would be fine with something like this: stooges = Stooges() And if a lookup for self.larry fails, something would check stooges and see if larry is there. (But it must also work if a subclass tries to do larry = 'blah' at the class level.) Summary Want to replace related groups of attributes in a parent class with a single attribute that stores all the data elsewhere Want to work with existing client code that uses (e.g.) larry = 'blah' at the class level Want to continue to allow subclasses to extend, override, and modify these refactored attributes without knowing anything has changed Is this possible? Or am I barking up the wrong tree?

ASP.NET Horizontal Menu Control

A few weeks ago, I was working on an ASP.NET web application and needed a simple horizontal menu with a submenu. I decided to use ASP.NET's Menu control: Just drag and drop the control on to the page. Simple enough, but the control did not provide access key and target window support on menu items. I have put together a tutorial on how to include an access key attribute, include a target attribute, and include a site map path.

New Worklist features on 12.1.3

- by Vijay Shanmugam

Following new Worklist features are available on E-Business Suite 12.1.3 via Patch 13646173. Ability to view comments on top of a notification If an action is performed on a notification such as Reassign, Request for Information or Provide Information, the recipient of the notification will see who performed the last action and the associated comment on top of the notification. Reassigning a request for information notification If an approver requests more information on a notification from it's submitter, the submitter now has two options Answer Request for More Information Transfer Request for More Information If the submitter thinks the requested information can be provided by another user, he/she can transfer the request to the other user. Please note that only Transfer is supported for Request for More Information. Once transferred, the submitter cannot access the notification and provide the requested information. Use actual sent date when reassigning a notification The Sent field in notification header always showed the date on which the notification was first created. If the notification was later reassigned, the Sent date was not updated to show the last action date. This caused problems in following scenario Approval notification was sent to JACK on 01-JAN-2012 JACK waited for 10 days before reassigning to JILL on 10-JAN-2012 JILL does not see the notification as sent on 10-JAN-2012, instead sees it as sent on 01-JAN-2012 Although the notification was originally created on 01-JAN-2012, it was sent to JILL only on 10-JAN-2012 The enhancement now shows the correct sent date in Worklist and Notification Details page. Figure 1 - Depicts all the above 3 features Related Action History for response required notification So far it was possible to embed Action History of an response-required notification into another FYI notification using #RELATED_HISTORY attribute (Please refer to Workflow Developer Guide for details about this attribute). The enhancement now enables developers to embed Action History of one response-required notification into another response-required notification. To embed Action History of one response-required notification into another, create message attribute #RELATED_HISTORY. To this attribute set a value during run-time in the following format. {TITLE}[ITEM_TYPE:ITEM_KEY]PROCESS_NAME:ACTIVITY_LABEL_NAMEThe TITLE, ITEM_TYPE and ITEM_KEY are optional values. TITLE is used as Related Action History header title. If TITLE is not present, then a default title "Related Action History" is shown. If ITEM_TYPE is present and ITEM_KEY is not, For Example: {TITLE}[ITEM_TYPE]PROCESS_NAME:ACTIVITY_LABEL_NAME , the Related Action History is populated from parent item type of the current item. If both ITEM_TYPE and ITEM_KEY is present, For Example: {TITLE}[ITEM_TYPE:ITEM_KEY]PROCESS_NAME:ACTIVITY_LABEL_NAME , the Related Action History is populated from that specific instance activity.

What's the best way to expose a Model object in a ViewModel?

- by Angel

In a WPF MVVM application, I exposed my model object into my viewModel by creating an instance of Model class (which cause dependency) into ViewModel. Instead of creating separate VM properties, I wrap the Model properties inside my ViewModel Property. My model is just an entity framework generated proxy class: public partial class TblProduct { public TblProduct() { this.TblPurchaseDetails = new HashSet<TblPurchaseDetail>(); this.TblPurchaseOrderDetails = new HashSet<TblPurchaseOrderDetail>(); this.TblSalesInvoiceDetails = new HashSet<TblSalesInvoiceDetail>(); this.TblSalesOrderDetails = new HashSet<TblSalesOrderDetail>(); } public int ProductId { get; set; } public string ProductCode { get; set; } public string ProductName { get; set; } public int CategoryId { get; set; } public string Color { get; set; } public Nullable<decimal> PurchaseRate { get; set; } public Nullable<decimal> SalesRate { get; set; } public string ImagePath { get; set; } public bool IsActive { get; set; } public virtual TblCompany TblCompany { get; set; } public virtual TblProductCategory TblProductCategory { get; set; } public virtual TblUser TblUser { get; set; } public virtual ICollection<TblPurchaseDetail> TblPurchaseDetails { get; set; } public virtual ICollection<TblPurchaseOrderDetail> TblPurchaseOrderDetails { get; set; } public virtual ICollection<TblSalesInvoiceDetail> TblSalesInvoiceDetails { get; set; } public virtual ICollection<TblSalesOrderDetail> TblSalesOrderDetails { get; set; } } Here is my ViewModel: public class ProductViewModel : WorkspaceViewModel { #region Constructor public ProductViewModel() { StartApp(); } #endregion //Constructor #region Properties private IProductDataService _dataService; public IProductDataService DataService { get { if (_dataService == null) { if (IsInDesignMode) { _dataService = new ProductDataServiceMock(); } else { _dataService = new ProductDataService(); } } return _dataService; } } //Get and set Model object private TblProduct _product; public TblProduct Product { get { return _product ??

I know this will cause a strong dependency. So: What's the best way to expose a Model object in a ViewModel? What's the best way to use DataService in VM?

MVVM- Expose Model object in ViewModel

- by Angel

I have a wpf MVVM application , I exposed my model object into my viewModel by creating an instance of Model class (which cause dependency) into ViewModel , and instead of creating seperate VM properties , I wrap the Model properties inside my ViewModel Property. My model is just an entity framework generated proxy classes.

DNS protocol message example

- by virtual-lab

hello there, I am trying to figure out how to send out DNS messages from an application socket adapter to a DNSBL. I spent the last two days understanding the basics, including experimenting with WireShark to catch an example of message exchanged. Now I would like to query the DNS without using dig or host command (I'm using Ubuntu); how can I perform this action at low level, without the help of these tools in wrapping the request in a proper DNS message format? How the message should be post it? Hex or String? Thanks in advance for any help. Regards Alessandro Ilardo Comment added I am investigating on JDev and Oracle SOA. The platform provides a Socket Adapter which simply apply a transformation (XSLT) and send the message straight to the socket. How the payload parameters (ex. the host I'm looking up) are wrapped within the message is left to the developer. So basically I have an idea on how the all DNS message is structured, but rather than put everything on JDev stright away I'd like to make some tests on my own just to make sure I got a valid message format. So, I am not using any specific language (I don't even understand why they moved my question from serverfault) and I don't want to use any tools which would hide part of the message, such as the header. I know they work well btw. I guess this stuff has something to do with packet injection. Someone suggested me to use telnet, but I've only used for SMTP or HTTP, I haven't got a clue on how it works for DNS request. Does it make more sense now?

Windows Azure: Announcing Support for Windows Server 2012 R2 + Some Nice Price Cuts

- by ScottGu

Today we released some great updates to Windows Azure: Virtual Machines: Support for Windows Server 2012 R2 Cloud Services: Support for Windows Server 2012 R2 and .NET 4.5.1 Windows Azure Pack: Use Windows Azure features on-premises using Windows Server 2012 R2 Price Cuts: Up to 22% Price Reduction on Memory-Intensive Instances Below are more details about each of the improvements: Virtual Machines: Support for Windows Server 2012 R2 This morning we announced the release of Windows Server 2012 R2 – which is a fantastic update to Windows Server and includes a ton of great enhancements. This morning we are also excited to announce that the general availability image of Windows Server 2012 RC is now supported on Windows Azure. Windows Azure is the first cloud provider to offer the final release of Windows Server 2012 R2, and it is incredibly easy to launch your own Windows Server 2012 R2 instance with it. To create a new Windows Server 2012 R2 instance simply choose New->Compute->Virtual Machine within the Windows Azure Management Portal. You can select the “Windows Server 2012 R2” image and create a new Virtual Machine using the “Quick Create” option: Or alternatively click the “From Gallery” option if you want to customize even more configuration options (endpoints, remote powershell, availability set, etc): Creating and instantiating a new Virtual Machine on Windows Azure is very fast. In fact, the Windows Server 2012 R2 image now deploys and runs 30% faster than previous versions of Windows Server. Once the VM is deployed you can drill into it to track its health and manage its settings: Clicking the “Connect” button allows you to remote desktop into the VM – at which point you can customize and manage it as a full administrator however you want: If you haven’t tried Windows Server 2012 R2 yet – give it a try with Windows Azure. There is no easier way to get an instance of it up and running! Cloud Services: Support for using Windows Server 2012 R2 with Web and Worker Roles Today’s Windows Azure release also allows you to now use Windows Server 2012 R2 and .NET 4.5.1 within Web and Worker Roles within Cloud Service based applications. Enabling this is easy. You can configure existing existing Cloud Service application to use Windows Server 2012 R2 by updating your Cloud Service Configuration File (.cscfg) to use the new “OS Family 4” setting: Or alternatively you can use the Windows Azure Management Portal to update cloud services that are already deployed on Windows Azure. Simply choose the configure tab on them and select Windows Server 2012 R2 in the Operating System Family dropdown: The approaches above enable you to immediately take advantage of Windows Server 2012 R2 and .NET 4.5.1 and all the great features they provide. Windows Azure Pack: Use Windows Azure features on Windows Server 2012 R2 Today we also made generally available the Windows Azure Pack, which is a free download that enables you to run Windows Azure Technology within your own datacenter, an on-premises private cloud environment, or with one of our service provider/hosting partners who run Windows Server. Windows Azure Pack enables you to use a management portal that has the exact same UI as the Windows Azure Management Portal, and within which you can create and manage Virtual Machines, Web Sites, and Service Bus – all of which can run on Windows Server and System Center. The services provided with the Windows Azure Pack are consistent with the services offered within our Windows Azure public cloud offering. This consistency enables organizations and developers to build applications and solutions that can run in any hosting environment – and which use the same development and management approach. The end result is an offering with incredible flexibility. You can learn more about Windows Azure Pack and download/deploy it today here. Price Cuts: Up to 22% Reduction on Memory Intensive Instances Today we are also reducing prices by up to 22% on our memory-intensive VM instances (specifically our A5, A6, and A7 instances). These price reductions apply to both Windows and Linux VM instances, as well as for Cloud Service based applications: These price reductions will take effect in November, and will enable you to run applications that demand larger memory (such as SharePoint, Databases, in-memory analytics, etc) even more cost effectively. Summary Today’s release enables you to start using Windows Server 2012 R2 within Windows Azure immediately, and take advantage of our Cloud OS vision both within our datacenters – and using the Windows Azure Pack within both your existing datacenters and those of our partners. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today. Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu
