• The Microsoft Ajax Library and Visual Studio Beta 2

  - by Stephen Walther

  Visual Studio 2010 Beta 2 was released this week and one of the first things that I hope you notice is that it no longer contains the latest version of ASP.NET AJAX. What happened? Where did AJAX go? Just like Sting and The Police, just like Phil Collins and Genesis, just like Greg Page and the Wiggles, AJAX has gone out of band! We are starting a solo career. A Name Change First things first. In previous releases, our Ajax framework was named ASP.NET AJAX. We now have changed the name of the framework to the Microsoft Ajax Library. There are two reasons behind this name change. First, the members of the Ajax team got tired of explaining to everyone that our Ajax framework is not tied to the server-side ASP.NET framework. You can use the Microsoft Ajax Library with ASP.NET Web Forms, ASP.NET MVC, PHP, Ruby on RAILS, and even pure HTML applications. Our framework can be used as a client-only framework and having the word ASP.NET in our name was confusing people. Second, it was time to start spelling the word Ajax like everyone else. Notice that the name is the Microsoft Ajax Library and not the Microsoft AJAX library. Originally, Microsoft used upper case AJAX because AJAX originally was an acronym for Asynchronous JavaScript and XML. And, according to Strunk and Wagnell, acronyms should be all uppercase. However, Ajax is one of those words that have migrated from acronym status to “just a word” status. So whenever you hear one of your co-workers talk about ASP.NET AJAX, gently correct your co-worker and say “It is now called the Microsoft Ajax Library.” Why OOB? But why move out-of-band (OOB)? The short answer is that we have had approximately 6 preview releases of the Microsoft Ajax Library over the last year. That’s a lot. We pride ourselves on being agile. Client-side technology evolves quickly. We want to be able to get a preview version of the Microsoft Ajax Library out to our customers, get feedback, and make changes to the library quickly. Shipping the Microsoft Ajax Library out-of-band keeps us agile and enables us to continue to ship new versions of the library even after ASP.NET 4 ships. Showing Love for JavaScript Developers One area in which we have received a lot of feedback is around making the Microsoft Ajax Library easier to use for developers who are comfortable with JavaScript. We also wanted to make it easy for jQuery developers to take advantage of the innovative features of the Microsoft Ajax Library. To achieve these goals, we’ve added the following features to the Microsoft Ajax Library (these features are included in the latest preview release that you can download right now): A simplified imperative syntax – We wanted to make it brain-dead simple to create client-side Ajax controls when writing JavaScript. A client script loader – We wanted the Microsoft Ajax Library to load all of the scripts required by a component or control automatically. jQuery integration – We love the jQuery selector syntax. We wanted to make it easy for jQuery developers to use the Microsoft Ajax Library without changing their programming style. If you are interested in learning about these new features of the Microsoft Ajax Library, I recommend that you read the following blog post by Scott Guthrie: http://weblogs.asp.net/scottgu/archive/2009/10/15/announcing-microsoft-ajax-library-preview-6-and-the-microsoft-ajax-minifier.aspx Downloading the Latest Version of the Microsoft Ajax Library Currently, the best place to download the latest version of the Microsoft Ajax Library is directly from the ASP.NET CodePlex project: http://aspnet.codeplex.com/ As I write this, the current version is Preview 6. The next version is coming out at the PDC. Summary I’m really excited about the future of the Microsoft Ajax Library. Moving outside of the ASP.NET framework provides us the flexibility to remain agile and continue to innovate aggressively. The latest preview release of the Microsoft Ajax Library includes several major new features including a client script loader, jQuery integration, and a simplified client control creation syntax.

• Installing the Updated XP Mode which Requires no Hardware Virtualization

  - by Mysticgeek

  Good news for those of you who have a computer without Hardware Virtualization, Microsoft had dropped the requirement so you can now run XP Mode on your machine. Here we take a look at how to install it and getting working on your PC. Microsoft has dropped the requirement that your CPU supports Hardware Virtualization for XP Mode in Windows 7. Before this requirement was dropped, we showed you how to use SecureAble to find out if your machine would run XP Mode. If it couldn’t, you might have gotten lucky with turning Hardware Virtualization on in your BIOS, or getting an update that would enable it. If not, you were out of luck or would need a different machine. Note: Although you no longer need Hardware Virtualization, you still need Professional, Enterprise, or Ultimate version of Windows 7. Download Correct Version of XP Mode For this article we’re installing it on a Dell machine that doesn’t support Hardware Virtualization on Windows 7 Ultimate 64-bit version. The first thing you’ll want to do is go to the XP Mode website and select your edition of Windows 7 and language. Then there are three downloads you’ll need to get from the page. Windows XP Mode, Windows Virtual PC, and the Windows XP Mode Update (All Links Below). Windows genuine validation is required before you can download the XP Mode files. To make the validation process easier you might want to use IE when downloading these files and validating your version of Windows. Installing XP Mode After validation is successful the first thing to download and install is XP Mode, which is easy following the wizard and accepting the defaults. The second step is to install KB958559 which is Windows Virtual PC.   After it’s installed, a reboot is required. After you’ve come back from the restart, you’ll need to install KB977206 which is the Windows XP Mode Update.   After that’s installed, yet another restart of your system is required. After the update is configured and you return from the second reboot, you’ll find XP Mode in the Start menu under the Windows Virtual PC folder. When it launches accept the license agreement and click Next. Enter in your log in credentials… Choose if you want Automatic Updates or not… Then you’re given a message saying setup will share the hardware on your computer, then click Start Setup. While setup completes, you’re shown a display of what XP Mode does and how to use it. XP Mode launches and you can now begin using it to run older applications that are not compatible with Windows 7. Conclusion This is a welcome news for many who want the ability to use XP Mode but didn’t have the proper hardware to do it. The bad news is users of Home versions of Windows still don’t get to enjoy the XP Mode feature officially. However, we have an article that shows a great workaround – Create an XP Mode for Windows 7 Home Versions & Vista.

• Interview questions about ASP.NET Web services.

  - by Jalpesh P. Vadgama

  I have seen there are lots of myth’s about asp.net web services in fresher level asp.net developers. So I decided to write a blog post about asp.net web services interview questions. Because I think this is the best way to reach fresher asp.net developers. Followings are few questions about asp.net web services. 1) What is asp.net web services? Ans: Web services are used to support http requests that formatted using xml,http and SOAP syntax. They interact with through standards xml messages through Soap. They are used to support interoperability. It has .asmx extension and .NET framework contains http handlers for web services to support http requested directly. 2) What kind of data can be returned web services web methods? Ans: It supports all the primitive data types and custom data types that can be encoded and serialized by xml. You can find more information about that from the following link. http://msdn.microsoft.com/en-us/library/bb552900.aspx 3) Is web services are only written in asp.net? Ans: No, It can be written by Java and PHP languages also. 4) Explain web method attributes in web services Ans: Web method attributes are added to a public class method to indicate that this method is exposed as a part of XML web services. You can have multiple web methods in a class. But it should be having public attributes as it will be exposed as xml web service part. You can find more information about web method attributes from following link. http://msdn.microsoft.com/en-us/library/byxd99hx(v=vs.71).aspx 5) What is SOA? Ans: SOA stands for “Services Oriented Architecture”. It is kind of service oriented architecture used to support different kind of computing platforms and applications. Web services in asp.net are one of the technologies that supports that kind of architecture.  You can call asp.net web services from any computing platforms and applications. 6) What is SOAP,WDSL and UDDI? Ans: SOAP stands “Simple Object Access protocol”. Web services will be interact with SOAP messages written in XML. SOAP is sometimes referred as “data wrapper” or “data envelope”.Its contains different xml tag that creates a whole SOAP message.  WSDL stand for “Web services Description Language”.  It is an xml document which is written according to standard specified by W3c. It is a kind of manual or document that describes how we can use and consume web service. Web services development software processes the WSDL document and generates SOAP messages that are needed for specific web service. UDDI stand for “Universal Discovery, Description and Integration”. Its is used for web services registries. You can find addresses of web services from UDDI.

• How To Disable Control Panel in Windows 7

  - by Mysticgeek

  If you have a shared computer that your family and friends can access, you might not want them to mess around in the Control Panel, and luckily with a simple tweak you can disable it. Disable Control Panel with Group Policy Note: This process uses Local Group Policy Editor which is not available in Home versions of Windows 7. Skip down below for the registry hack version that works on Home editions as well. First type gpedit.msc into the Search box in the Start menu and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select Control Panel in the left Column. In the right column double-click on Prohibit access to the Control Panel. In the next window, select Enable, click OK, then close out of Local Group Policy Editor. After the Control Panel is disabled, you’ll notice it’s no longer listed in the Start Menu. If the user tries to type Control Panel into the Search box in the Start menu, they will get the following message indicating it’s restricted. Disable Control Panel with a Registry Tweak You can also tweak the Registry to disable Control Panel. This will work with all versions of Windows 7, Vista, and XP. Making changes in the Registry is not recommended for beginners and you should create a Restore Point, or backup the Registry before making any changes. Type regedit into the Search box in the Start menu and hit Enter. In Registry Editor navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer. Then right-click in the right pane and create a new DWORD (32-bit) Value. Name the value NoControlPanel. Then right-click on the new Value and click Modify…   In the Value data field change the value to “1” then click OK. Close out of Registry Editor and restart the machine to complete the process. When you get back from reboot, you’ll notice Control Panel is no longer listed in the Start menu. If a user tries to access it by typing Control Panel into the Search box in the Start menu… They will get the following message indicating it is restricted, just like if you were to disable it via Group Policy. If you want to re-enable the Control Panel, go back into the Registry and change the NoControlPanel value back to “0” then reboot the computer. This comes in handy if you have inexperienced users working on your machine and don’t want them messing with Control Panel settings.

• Parallelism in .NET – Part 20, Using Task with Existing APIs

  - by Reed

  Although the Task class provides a huge amount of flexibility for handling asynchronous actions, the .NET Framework still contains a large number of APIs that are based on the previous asynchronous programming model.  While Task and Task<T> provide a much nicer syntax as well as extending the flexibility, allowing features such as continuations based on multiple tasks, the existing APIs don’t directly support this workflow. There is a method in the TaskFactory class which can be used to adapt the existing APIs to the new Task class: TaskFactory.FromAsync.  This method provides a way to convert from the BeginOperation/EndOperation method pair syntax common through .NET Framework directly to a Task<T> containing the results of the operation in the task’s Result parameter. While this method does exist, it unfortunately comes at a cost – the method overloads are far from simple to decipher, and the resulting code is not always as easily understood as newer code based directly on the Task class.  For example, a single call to handle WebRequest.BeginGetResponse/EndGetReponse, one of the easiest “pairs” of methods to use, looks like the following: var task = Task.Factory.FromAsync<WebResponse>( request.BeginGetResponse, request.EndGetResponse, null); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The compiler is unfortunately unable to infer the correct type, and, as a result, the WebReponse must be explicitly mentioned in the method call.  As a result, I typically recommend wrapping this into an extension method to ease use.  For example, I would place the above in an extension method like: public static class WebRequestExtensions { public static Task<WebResponse> GetReponseAsync(this WebRequest request) { return Task.Factory.FromAsync<WebResponse>( request.BeginGetResponse, request.EndGetResponse, null); } } This dramatically simplifies usage.  For example, if we wanted to asynchronously check to see if this blog supported XHTML 1.0, and report that in a text box to the user, we could do: var webRequest = WebRequest.Create("http://www.reedcopsey.com"); webRequest.GetReponseAsync().ContinueWith(t => { using (var sr = new StreamReader(t.Result.GetResponseStream())) { string str = sr.ReadLine();; this.textBox1.Text = string.Format("Page at {0} supports XHTML 1.0: {1}", t.Result.ResponseUri, str.Contains("XHTML 1.0")); } }, TaskScheduler.FromCurrentSynchronizationContext());   By using a continuation with a TaskScheduler based on the current synchronization context, we can keep this request asynchronous, check based on the first line of the response string, and report the results back on our UI directly.

• Performance and Optimization Isn’t Evil

  - by Reed

  Donald Knuth is a fairly amazing guy.  I consider him one of the most influential contributors to computer science of all time.  Unfortunately, most of the time I hear his name, I cringe.  This is because it’s typically somebody quoting a small portion of one of his famous statements on optimization: “premature optimization is the root of all evil.” I mention that this is only a portion of the entire quote, and, as such, I feel that Knuth is being quoted out of context.  Optimization is important.  It is a critical part of every software development effort, and should never be ignored.  A developer who ignores optimization is not a professional.  Every developer should understand optimization – know what to optimize, when to optimize it, and how to think about code in a way that is intelligent and productive from day one. I want to start by discussing my own, personal motivation here.  I recently wrote about a performance issue I ran across, and was slammed by multiple comments and emails that effectively boiled down to: “You’re an idiot.  Premature optimization is the root of all evil.  This doesn’t matter.”  It didn’t matter that I discovered this while measuring in a profiler, and that it was a portion of my code base that can take “many hours to complete.”  Even so, multiple people instantly jump to “it’s premature – it doesn’t matter.” This is a common thread I see.  For example, StackOverflow has many pages of posts with answers that boil down to (mis)quoting Knuth.  In fact, just about any question relating to a performance related issue gets this quote thrown at it immediately – whether it deserves it or not.  That being said, I did receive some positive comments and emails as well.  Many people want to understand how to optimize their code, approaches to take, tools and techniques they can use, and any other advice they can discover. First, lets get back to Knuth – I mentioned before that Knuth is being quoted out of context.  Lets start by looking at the entire quote from his 1974 paper Structured Programming with go to Statements: “We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified.” Ironically, if you read Knuth’s original paper, this statement was made in the middle of a discussion of how Knuth himself had changed how he approaches optimization.  It was never a statement saying “don’t optimize”, but rather, “optimizing intelligently provides huge advantages.”  His approach had three benefits: “a) it doesn’t take long” … “b) the payoff is real”, c) you can “be less efficient in the other parts of my programs, which therefore are more readable and more easily written and debugged.” Looking at Knuth’s premise here, and reading that section of his paper, really leads to a few observations: Optimization is important  “he will be wise to look carefully at the critical code” Normally, 3% of your code – three lines out of every 100 you write, are “critical code” and will require some optimization: “we should not pass up our opportunities in that critical 3%” Optimization, if done well, should not be time consuming: “it doesn’t take long” Optimization, if done correctly, provides real benefits: “the payoff is real” None of this is new information.  People who care about optimization have been discussing this for years – for example, Rico Mariani’s Designing For Performance (a fantastic article) discusses many of the same issues very intelligently. That being said, many developers seem unable or unwilling to consider optimization.  Many others don’t seem to know where to start.  As such, I’m going to spend some time writing about optimization – what is it, how should we think about it, and what can we do to improve our own code.

Today I will show you how to install the preview. 1. Create a service account called SP2013Install and give this account Dbcreator and SecurityAdmin in SQL Server 2012 2. You need to run the following script to set the ‘maxdegree of parellism’ setting to the required value of 1 in SQL Server 2012(using sysadmin privilege) before configure the SharePoint Farm. Otherwise , you might get the error ‘This SQL Server Instance does not have the required maxdegree of parellism setting of 1’ sp_configure 'show advanced options', 1; GO RECONFIGURE WITH OVERRIDE; GO sp_configure 'max degree of parallelism', 1; GO RECONFIGURE WITH OVERRIDE; GO 3. Download the SharePoint preview from here and I am going to install it on Windows Server 2008R2 with SQL2012. 4. Click the Install software prerequisites, this works fine with the internet connection. (However, if you do not have internet connection, it is a bit tricky to install window azure AppFabric as it has to be installed using the prerequisite installer. Your computer might reboot a few times in the process.) 5.After the prerequisites are installed `completely, you can then install the Preview. Click the Install SharePoint Server and Enter the Product key you get from the Preview download page. 6. Accept the License terms and Click Next. 7. Leave the default path for the file location. 8. You can now start the installation process 9. After binary files are installed, you then can configure your farm using the farm configuration wizard. 10.Specify the Database server and the install account 11. Specify SharePoint farm passphrase. 12 Specify the port number , you should choose your own favorite port number. 13. Choose Create a New Server Farm and click next. 14. Double-check with the settings and click Next to Configure the farm install. 15. Finally, your farm is configured successfully and you now are able to go to your Central Admin site http://sp2010:6666/ 16. You should configure the services manually or automate using PowerShell (If you like to understand why,you can read the blog post here) ,however I will use the wizard to configure automatically here  as  this is a test machine. After the configuration is complete, you now be able to see your SharePoint Site. 17.To start the evaluate the Preview , you need to install Visual Studio 2012 RC , Microsoft Office Developer Tools for Visual Studio 2012,SharePoint 2013 Designer Preview , Office 2013 Preview.

• C# Proposal: Compile Time Static Checking Of Dynamic Objects

  - by Paulo Morgado

  C# 4.0 introduces a new type: dynamic. dynamic is a static type that bypasses static type checking. This new type comes in very handy to work with: The new languages from the dynamic language runtime. HTML Document Object Model (DOM). COM objects. Duck typing … Because static type checking is bypassed, this: dynamic dynamicValue = GetValue(); dynamicValue.Method(); is equivalent to this: object objectValue = GetValue(); objectValue .GetType() .InvokeMember( "Method", BindingFlags.InvokeMethod, null, objectValue, null); Apart from caching the call site behind the scenes and some dynamic resolution, dynamic only looks better. Any typing error will only be caught at run time. In fact, if I’m writing the code, I know the contract of what I’m calling. Wouldn’t it be nice to have the compiler do some static type checking on the interactions with these dynamic objects? Imagine that the dynamic object that I’m retrieving from the GetValue method, besides the parameterless method Method also has a string read-only Property property. This means that, from the point of view of the code I’m writing, the contract that the dynamic object returned by GetValue implements is: string Property { get; } void Method(); Since it’s a well defined contract, I could write an interface to represent it: interface IValue { string Property { get; } void Method(); } If dynamic allowed to specify the contract in the form of dynamic(contract), I could write this: dynamic(IValue) dynamicValue = GetValue(); dynamicValue.Method(); This doesn’t mean that the value returned by GetValue has to implement the IValue interface. It just enables the compiler to verify that dynamicValue.Method() is a valid use of dynamicValue and dynamicValue.OtherMethod() isn’t. If the IValue interface already existed for any other reason, this would be fine. But having a type added to an assembly just for compile time usage doesn’t seem right. So, dynamic could be another type construct. Something like this: dynamic DValue { string Property { get; } void Method(); } The code could now be written like this; DValue dynamicValue = GetValue(); dynamicValue.Method(); The compiler would never generate any IL or metadata for this new type construct. It would only thee used for compile type static checking of dynamic objects. As a consequence, it makes no sense to have public accessibility, so it would not be allowed. Once again, if the IValue interface (or any other type definition) already exists, it can be used in the dynamic type definition: dynamic DValue : IValue, IEnumerable, SomeClass { string Property { get; } void Method(); } Another added benefit would be IntelliSense. I’ve been getting mixed reactions to this proposal. What do you think? Would this be useful?

• Creating PDF documents dynamically using Umbraco and XSL-FO part 2

  - by Vizioz Limited

  Since my last post I have made a few modifications to the PDF generation, the main one being that the files are now dynamically renamed so that they reflect the name of the case study instead of all being called PDF.PDF which was not a very helpful filename, I just wanted to get something live last week, so decided that something was better than nothing :)The issue with the filenames comes down to the way that the PDF's are being generated by using an alternative template in Umbraco, this means that all you need to do is add " /pdf " to the end of a case study URL and it will create a PDF version of the case study. The down side is that your browser will merrily download the file and save it as PDF.PDF because that is the name of the last part of the URL.What you need to do is set the content-disposition header to be equal to the name you would like the file use, Darren Ferguson mentioned this on the Change the name of the PDF forum post.We have used the same technique for downloading dynamically generated excel files, so I thought it would be useful to create a small macro to set both this header and also to set the caching headers to prevent any caching issues, I think in the past we have experienced all possible issues, including various issues where IE behaves differently to other browsers when you are using SSL and so the below code should work in all situations!The template for the PDF alternative template is very simple:<%@ Master Language="C#" MasterPageFile="~/umbraco/masterpages/default.master" AutoEventWireup="true" %><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolderDefault" runat="server"> <umbraco:Macro Alias="PDFHeaders" runat="server"></umbraco:Macro> <umbraco:Macro xsl="FO-CaseStudy.xslt" Alias="PDFXSLFO" runat="server"></umbraco:Macro></asp:Content>The following code snippet is the XSLT macro that simply creates our file name and then passes the file name into the helper function:<xsl:template match="/"> <xsl:variable name="fileName"> <xsl:text>Vizioz_</xsl:text> <xsl:value-of select="$currentPage/@nodeName" /> <xsl:text>_case_study.pdf</xsl:text> </xsl:variable> <xsl:value-of select="Vizioz.Helper:AddDocumentDownloadHeaders('application/pdf', $fileName)"/> </xsl:template>And the following code is the helper function that clears the current response and adds all the appropriate headers:public static void AddDocumentDownloadHeaders(string contentType, string fileName){ HttpResponse response = HttpContext.Current.Response; HttpRequest request = HttpContext.Current.Request; response.Clear(); response.ClearHeaders(); if (request.IsSecureConnection & request.Browser.Browser == "IE") { // Don't use the caching headers if the browser is IE and it's a secure connection // see: http://support.microsoft.com/kb/323308 } else { // force not using the cache response.AppendHeader("Cache-Control", "no-cache"); response.AppendHeader("Cache-Control", "private"); response.AppendHeader("Cache-Control", "no-store"); response.AppendHeader("Cache-Control", "must-revalidate"); response.AppendHeader("Cache-Control", "max-stale=0"); response.AppendHeader("Cache-Control", "post-check=0"); response.AppendHeader("Cache-Control", "pre-check=0"); response.AppendHeader("Pragma", "no-cache"); response.Cache.SetCacheability(HttpCacheability.NoCache); response.Cache.SetNoStore(); response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1)); } response.AppendHeader("Expires", DateTime.Now.AddMinutes(-1).ToLongDateString()); response.AppendHeader("Keep-Alive", "timeout=3, max=993"); response.AddHeader("content-disposition", "attachment; filename=\"" + fileName + "\""); response.ContentType = contentType;}I will write another blog soon with some more details about XSL-FO and how to create the PDF's dynamically.Please do re-tweet if you find this interest :)

• Big Data – Buzz Words: What is MapReduce – Day 7 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned what is Hadoop. In this article we will take a quick look at one of the four most important buzz words which goes around Big Data – MapReduce. What is MapReduce? MapReduce was designed by Google as a programming model for processing large data sets with a parallel, distributed algorithm on a cluster. Though, MapReduce was originally Google proprietary technology, it has been quite a generalized term in the recent time. MapReduce comprises a Map() and Reduce() procedures. Procedure Map() performance filtering and sorting operation on data where as procedure Reduce() performs a summary operation of the data. This model is based on modified concepts of the map and reduce functions commonly available in functional programing. The library where procedure Map() and Reduce() belongs is written in many different languages. The most popular free implementation of MapReduce is Apache Hadoop which we will explore tomorrow. Advantages of MapReduce Procedures The MapReduce Framework usually contains distributed servers and it runs various tasks in parallel to each other. There are various components which manages the communications between various nodes of the data and provides the high availability and fault tolerance. Programs written in MapReduce functional styles are automatically parallelized and executed on commodity machines. The MapReduce Framework takes care of the details of partitioning the data and executing the processes on distributed server on run time. During this process if there is any disaster the framework provides high availability and other available modes take care of the responsibility of the failed node. As you can clearly see more this entire MapReduce Frameworks provides much more than just Map() and Reduce() procedures; it provides scalability and fault tolerance as well. A typical implementation of the MapReduce Framework processes many petabytes of data and thousands of the processing machines. How do MapReduce Framework Works? A typical MapReduce Framework contains petabytes of the data and thousands of the nodes. Here is the basic explanation of the MapReduce Procedures which uses this massive commodity of the servers. Map() Procedure There is always a master node in this infrastructure which takes an input. Right after taking input master node divides it into smaller sub-inputs or sub-problems. These sub-problems are distributed to worker nodes. A worker node later processes them and does necessary analysis. Once the worker node completes the process with this sub-problem it returns it back to master node. Reduce() Procedure All the worker nodes return the answer to the sub-problem assigned to them to master node. The master node collects the answer and once again aggregate that in the form of the answer to the original big problem which was assigned master node. The MapReduce Framework does the above Map () and Reduce () procedure in the parallel and independent to each other. All the Map() procedures can run parallel to each other and once each worker node had completed their task they can send it back to master code to compile it with a single answer. This particular procedure can be very effective when it is implemented on a very large amount of data (Big Data). The MapReduce Framework has five different steps: Preparing Map() Input Executing User Provided Map() Code Shuffle Map Output to Reduce Processor Executing User Provided Reduce Code Producing the Final Output Here is the Dataflow of MapReduce Framework: Input Reader Map Function Partition Function Compare Function Reduce Function Output Writer In a future blog post of this 31 day series we will explore various components of MapReduce in Detail. MapReduce in a Single Statement MapReduce is equivalent to SELECT and GROUP BY of a relational database for a very large database. Tomorrow In tomorrow’s blog post we will discuss Buzz Word – HDFS.

• SharePoint.DesignFactory.ContentFiles–building WCM sites

  - by svdoever

  One of the use cases where we use the SharePoint.DesignFactory.ContentFiles tooling is in building SharePoint Publishing (WCM) solutions for SharePoint 2007, SharePoint 2010 and Office365. Publishing solutions are often solutions that have one instance, the publishing site (possibly with subsites), that in most cases need to go through DTAP. If you dissect a publishing site, in most case you have the following findings: The publishing site spans a site collection The branding of the site is specified in the root site, because: Master pages live in the root site (/_catalogs/masterpage) Page layouts live in the root site (/_catalogs/masterpage) The style library lives in the root site ( /Style Library) and contains images, css, javascript, xslt transformations for your CQWP’s, … Preconfigured web parts live in the root site (/_catalogs/wp) The root site and subsites contains a document library called Pages (or your language-specific version of it) containing publishing pages using the page layouts and master pages The site collection contains content types, fields and lists When using the SharePoint.DesignFactory.ContentFiles tooling it is very easy to create, test, package and deploy the artifacts that can be uploaded to the SharePoint content database. This can be done in a fast and simple way without the need to create and deploy WSP packages. If we look at the above list of artifacts we can use SharePoint.DesignFactory.ContentFiles for master pages, page layouts, the style library, web part configurations, and initial publishing pages (these are normally made through the SharePoint web UI). Some artifacts like content types, fields and lists in the above list can NOT be handled by SharePoint.DesignFactory.ContentFiles, because they can’t be uploaded to the SharePoint content database. The good thing is that these artifacts are the artifacts that don’t change that much in the development of a SharePoint Publishing solution. There are however multiple ways to create these artifacts: Use paper script: create them manually in each of the environments based on documentation Automate the creation of the artifacts using (PowerShell) script Develop a WSP package to create these artifacts I’m not a big fan of the third option (see my blog post Thoughts on building deployable and updatable SharePoint solutions). It is a lot of work to create content types, fields and list definitions using all kind of XML files, and it is not allowed to modify these artifacts when in use. I know… SharePoint 2010 has some content type upgrade possibilities, but I think it is just too cumbersome. The first option has the problem that content types and fields get ID’s, and that these ID’s must be used by the metadata on for example page layouts. No problem for SharePoint.DesignFactory.ContentFiles, because it supports deploy-time resolving of these ID’s using PowerShell. For example consider the following metadata definition for the page layout contactpage-wcm.aspx.properties.ps1: Metadata page layout # This script must return a hashtable @{ name=value; ... } of field name-value pairs # for the content file that this script applies to. # On deployment to SharePoint, these values are written as fields in the corresponding list item (if any) # Note that fields must exist; they can be updated but not created or deleted. # This script is called right after the file is deployed to SharePoint.   # You can use the script parameters and arbitrary PowerShell code to interact with SharePoint. # e.g. to calculate properties and values at deployment time.   param([string]$SourcePath, [string]$RelativeUrl, $Context) @{     "ContentTypeId" = $Context.GetContentTypeID('GeneralPage');     "MasterPageDescription" = "Cloud Aviator Contact pagelayout (wcm - don't use)";     "PublishingHidden" = "1";     "PublishingAssociatedContentType" = $Context.GetAssociatedContentTypeInfo('GeneralPage') } The PowerShell functions GetContentTypeID and GetAssociatedContentTypeInfo can at deploy-time resolve the required information from the server we are deploying to. I personally prefer the second option: automate creation through PowerShell, because there are PowerShell scripts available to export content types and fields. An example project structure for a typical SharePoint WCM site looks like: Note that this project uses DualLayout. So if you build Publishing sites using SharePoint, checkout out the completely free SharePoint.DesignFactory.ContentFiles tooling and start flying!

• What is Agile Modeling and why do I need it?

  What is Agile Modeling and why do I need it? Agile Modeling is an add-on to existing agile methodologies like Extreme programming (XP) and Rational Unified Process (RUP). Agile Modeling enables developers to develop a customized software development process that actually meets their current development needs and is flexible enough to adjust in the future. According to Scott Ambler, Agile Modeling consists of five core values that enable this methodology to be effective and light weight Agile Modeling Core Values: Communication Simplicity Feedback Courage Humility Communication is a key component to any successful project. Open communication between stakeholder and the development team is essential when developing new applications or maintaining legacy systems. Agile models promote communication amongst software development teams and stakeholders. Furthermore, Agile Models provide a common understanding of an application for members of a software development team allowing them to have a universal common point of reference. The use of simplicity in Agile Models enables the exploration of new ideas and concepts through the use of basic diagrams instead of investing the time in writing tens or hundreds of lines of code. Feedback in regards to application development is essential. Feedback allows a development team to confirm that the development path is on track. Agile Models allow for quick feedback from shareholders because minimal to no technical expertise is required to understand basic models. Courage is important because you need to make important decisions and be able to change direction by either discarding or refactoring your work when some of your decisions prove inadequate, according to Scott Ambler. As a member of a development team, we must admit that we do not know everything even though some of us think we do. This is where humility comes in to play. Everyone is a knowledge expert in their own specific domain. If you need help with your finances then you would consult an accountant. If you have a problem or are in need of help with a topic why would someone not consult with a subject expert? An effective approach is to assume that everyone involved with your project has equal value and therefore should be treated with respect. Agile Model Characteristics: Purposeful Understandable Sufficiently Accurate Sufficiently Consistent Sufficiently Detailed Provide Positive Value Simple as Possible Just Fulfill Basic Requirements According to Scott Ambler, Agile models are the most effective possible because the time that is invested in the model is just enough effort to complete the job. Furthermore, if a model isn’t good enough yet then additional effort can be invested to get more value out of the model. However if a model is good enough, for the current needs, or surpass the current needs, then any additional work done on the model would be a waste. It is important to remember that good enough is in the eye of the beholder, so this can be tough. In order for Agile Models to work effectively Active Stakeholder need to participation in the modeling process. Finally it is also very important to model with others, this allows for additionally input ensuring that all the shareholders needs are reflected in the models. How can Agile Models be incorporated in to our projects? Agile Models can be incorporated in to our project during the requirement gathering and design phases. As requirements are gathered the models should be updated to incorporate the new project details as they are defined and updated. Additionally, the Agile Models created during the requirement phase can be the bases for the models created during the design phase.  It is important to only add to the model when the changes fit within the agile model characteristics and they do not over complicate the design.

  - by DigiMortal

     Writing code that is easy read and test is not something that is easy to achieve. Unfortunately there are still way too much programming students who write awful spaghetti after graduating. But there is one really good book that helps you raise your code to new level – your code will be also communication tool for you and your fellow programmers. “Clean Code: A Handbook of Agile Software Craftsmanship” by Robert C. Martin is excellent book that helps you start writing the easily readable code. Of course, you are the one who has to learn and practice but using this book you have very good guide that keeps you going to right direction. You can start writing better code while you read this book and you can do it right in your current projects – you don’t have to create new guestbook or some other simple application to start practicing. Take the project you are working on and start making it better! My special thanks to Robert C. Martin I want to say my special thanks to Robert C. Martin for this book. There are many books that teach you different stuff and usually you have markable learning curve to go before you start getting results. There are many books that show you the direction to go and then leave you alone figuring out how to achieve all that stuff you just read about. Clean Code gives you a lot more – the mental tools to use so you can go your way to clean code being sure you will be soon there. I am reading books as much as I have time for it. Clean Code is top-level book for developers who have to write working code. Before anything else take Clean Code and read it. You will never regret your decision. I promise. Fragment of editorial review “Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way. What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft. Readers will come away from this book understanding How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.” Table of contents Clean code Meaningful names Functions Comments Formatting Objects and data structures Error handling Boundaries Unit tests Classes Systems Emergence Concurrency Successive refinement JUnit internals Refactoring SerialDate Smells and heuristics A Concurrency II org.jfree.date.SerialDate Cross references of heuristics Epilogue Index

• Logging WebSocket Frames using Chrome Developer Tools, Net-internals and Wireshark (TOTD #184)

  - by arungupta

  TOTD #183 explained how to build a WebSocket-driven application using GlassFish 4. This Tip Of The Day (TOTD) will explain how do view/debug on-the-wire messages, or frames as they are called in WebSocket parlance, over this upgraded connection. This blog will use the application built in TOTD #183. First of all, make sure you are using a browser that supports WebSocket. If you recall from TOTD #183 then WebSocket is combination of Protocol and JavaScript API. A browser supporting WebSocket, or not, means they understand your web pages with the WebSocket JavaScript. caniuse.com/websockets provide a current status of WebSocket support in different browsers. Most of the major browsers such as Chrome, Firefox, Safari already support WebSocket for the past few versions. As of this writing, IE still does not support WebSocket however its planned for a future release. Viewing WebSocket farmes require special settings because all the communication happens over an upgraded HTTP connection over a single TCP connection. If you are building your application using Java, then there are two common ways to debug WebSocket messages today. Other language libraries provide different mechanisms to log the messages. Lets get started! Chrome Developer Tools provide information about the initial handshake only. This can be viewed in the Network tab and selecting the endpoint hosting the WebSocket endpoint. You can also click on "WebSockets" on the bottom-right to show only the WebSocket endpoints. Click on "Frames" in the right panel to view the actual frames being exchanged between the client and server. The frames are not refreshed when new messages are sent or received. You need to refresh the panel by clicking on the endpoint again. To see more detailed information about the WebSocket frames, you need to type "chrome://net-internals" in a new tab. Click on "Sockets" in the left navigation bar and then on "View live sockets" to see the page. Select the box with the address to your WebSocket endpoint and see some basic information about connection and bytes exchanged between the client and the endpoint. Clicking on the blue text "source dependency ..." shows more details about the handshake. If you are interested in viewing the exact payload of WebSocket messages then you need a network sniffer. These tools are used to snoop network traffic and provide a lot more details about the raw messages exchanged over the network. However because they provide lot more information so they need to be configured in order to view the relevant information. Wireshark (nee Ethereal) is a pretty standard tool for sniffing network traffic and will be used here. For this blog purpose, we'll assume that the WebSocket endpoint is hosted on the local machine. These tools do allow to sniff traffic across the network though. Wireshark is quite a comprehensive tool and we'll capture traffic on the loopback address. Start wireshark, select "loopback" and click on "Start". By default, all traffic information on the loopback address is displayed. That includes tons of TCP protocol messages, applications running on your local machines (like GlassFish or Dropbox on mine), and many others. Specify "http" as the filter in the top-left. Invoke the application built in TOTD #183 and click on "Say Hello" button once. The output in wireshark looks like Here is a description of the messages exchanged: Message #4: Initial HTTP request of the JSP page Message #6: Response returning the JSP page Message #16: HTTP Upgrade request Message #18: Upgrade request accepted Message #20: Request favicon Message #22: Responding with favicon not found Message #24: Browser making a WebSocket request to the endpoint Message #26: WebSocket endpoint responding back You can also use Fiddler to debug your WebSocket messages. How are you viewing your WebSocket messages ? Here are some references for you: JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) TOTD #183 - Getting Started with WebSocket in GlassFish Subsequent blogs will discuss the following topics (not necessary in that order) ... Binary data as payload Custom payloads using encoder/decoder Error handling Interface-driven WebSocket endpoint Java client API Client and Server configuration Security Subprotocols Extensions Other topics from the API

• PetaPoco with parameterised stored procedure and Asp.Net MVC

  - by Jalpesh P. Vadgama

  I have been playing with Micro ORMs as this is very interesting things that are happening in developer communities and I already liked the concept of it. It’s tiny easy to use and can do performance tweaks. PetaPoco is also one of them I have written few blog post about this. In this blog post I have explained How we can use the PetaPoco with stored procedure which are having parameters.  I am going to use same Customer table which I have used in my previous posts. For those who have not read my previous post following is the link for that. Get started with ASP.NET MVC and PetaPoco PetaPoco with stored procedures Now our customer table is ready. So let’s Create a simple process which will fetch a single customer via CustomerId. Following is a code for that. CREATE PROCEDURE mysp_GetCustomer @CustomerId as INT AS SELECT * FROM [dbo].Customer where CustomerId=@CustomerId Now  we are ready with our stored procedures. Now lets create code in CustomerDB class to retrieve single customer like following. using System.Collections.Generic; namespace CodeSimplified.Models { public class CustomerDB { public IEnumerable<Customer> GetCustomers() { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; return databaseContext.Query<Customer>("exec mysp_GetCustomers"); } public Customer GetCustomer(int customerId) { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; var customer= databaseContext.SingleOrDefault<Customer>("exec mysp_GetCustomer @customerId",new {customerId}); return customer; } } } Here in above code you can see that I have created a new method call GetCustomer which is having customerId as parameter and then I have written to code to use stored procedure which we have created to fetch customer Information. Here I have set EnableAutoSelect=false because I don’t want to create Select statement automatically I want to use my stored procedure for that. Now Our Customer DB class is ready and now lets create a ActionResult Detail in our controller like following using System.Web.Mvc; namespace CodeSimplified.Controllers { public class HomeController : Controller { public ActionResult Index() { ViewBag.Message = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return View(); } public ActionResult Customer() { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomers()); } public ActionResult Details(int id) { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomer(id)); } } } Now Let’s create view based on that ActionResult Details method like following. Now everything is ready let’s test it in browser. So lets first goto customer list like following. Now I am clicking on details for first customer and Let’s see how we can use the stored procedure with parameter to fetch the customer details and below is the output. So that’s it. It’s very easy. Hope you liked it. Stay tuned for more..Happy Programming

• Framework 4 Features: Support for Timed Jobs

  - by Anthony Shorten

  One of the new features of the Oracle Utilities Application Framework V4 is the ability for the batch framework to support Timed Batch. Traditionally batch is associated with set processing in the background in a fixed time frame. For example, billing customers. Over the last few versions their has been functionality required by the products required a more monitoring style batch process. The monitor is a batch process that looks for specific business events based upon record status or other pieces of data. For example, the framework contains a fact monitor (F1-FCTRN) that can be configured to look for specific status's or other conditions. The batch process then uses the instructions on the object to determine what to do. To support monitor style processing, you need to run the process regularly a number of times a day (for example, every ten minutes). Traditional batch could support this but it was not as optimal as expected (if you are a site using the old Workflow subsystem, you understand what I mean). The Batch framework was extended to add additional facilities to support times (and continuous batch which is another new feature for another blog entry). The new facilities include: The batch control now defines the job as Timed or Not Timed. Non-Timed batch are traditional batch jobs. The timer interval (the interval between executions) can be specified The timer can be made active or inactive. Only active timers are executed. Setting the Timer Active to inactive will stop the job at the next time interval. Setting the Timer Active to Active will start the execution of the timed job. You can specify the credentials, language to view the messages and an email address to send the a summary of the execution to. The email address is optional and requires an email server to be specified in the relevant feature configuration. You can specify the thread limits and commit intervals to be sued for the multiple executions. Once a timer job is defined it will be executed automatically by the Business Application Server process if the DEFAULT threadpool is active. This threadpool can be started using the online batch daemon (for non-production) or externally using the threadpoolworker utility. At that time any batch process with the Timer Active set to Active and Batch Control Type of Timed will begin executing. As Timed jobs are executed automatically then they do not appear in any external schedule or are managed by an external scheduler (except via the DEFAULT threadpool itself of course). Now, if the job has no work to do as the timer interval is being reached then that instance of the job is stopped and the next instance started at the timer interval. If there is still work to complete when the interval interval is reached, the instance will continue processing till the work is complete, then the instance will be stopped and the next instance scheduled for the next timer interval. One of the key ways of optimizing this processing is to set the timer interval correctly for the expected workload. This is an interesting new feature of the batch framework and we anticipate it will come in handy for specific business situations with the monitor processes.

• ASP.NET Server-side comments

  I believe a good number of you know about Server-side commenting. This blog is just like a revival to refresh your memories. When you write comments in your .aspx/.ascx files, people usually write them as: 1: <!-- This is a comment. --> To show that it actually makes a difference for using the server-side commenting technique, I’ve started a web application project and my default.aspx page looks like this: 1: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ServerSideComment._Default" %> 2: <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> 3: </asp:Content> 4: <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> 5: <h2> 6: <!-- This is a comment --> 7: Welcome to ASP.NET! 8: </h2> 9: <p> 10: To learn more about ASP.NET visit <a href="http://www.asp.net" title="ASP.NET Website">www.asp.net</a>. 11: </p> 12: <p> 13: You can also find <a href="http://go.microsoft.com/fwlink/?LinkID=152368&amp;clcid=0x409" 14: title="MSDN ASP.NET Docs">documentation on ASP.NET at MSDN</a>. 15: </p> 16: </asp:Content> See the comment in line 6 and when I run the app, I can do a view source on the browser which shows up as: 1: <h2> 2: <!-- This is a comment --> 3: Welcome to ASP.NET! 4: </h2> Using Fiddler shows the page size as: Let’s change the comment style and use server-side commenting technique. 1: <h2> 2: <%-- This is a comment --%> 3: Welcome to ASP.NET! 4: </h2> Upon rendering, the view source looks like: 1: <h2> 2: 3: Welcome to ASP.NET! 4: </h2> Fiddler now shows the page size as: The difference is that client-side comments are ignored by the browser, but they are still sent down the pipe. With server-side comments, the compiler ignores everything inside this block. Visual Studio’s Text Editor toolbar also puts comments as server-side ones. If you want to give it a shot, go to your design page and press Ctrl+K, Ctrl+C on some selected text and you’ll see it commented in the server-side commenting style.

  In this Issue: Tim Heuer(-2-), René Schulte(-2-), Bart Czernicki, Mark Monster, Pencho Popadiyn, Alex Golesh, Phil Middlemiss, and Yochay Kiriaty. Shoutouts: Check out the new themes, and Tim Heuer's poetry skills: SNEAK PEEK: New Silverlight application themes I learned to program Windows 3.1 from reading Charles Petzold's book, and here we are again: Free ebook: Programming Windows Phone 7 Series (DRAFT Preview) Here's a blog you're going to want to watch, and first up on the blog tonight is links to the complete set of MIX10 phone sessions: The Windows Phone Developer Blog First let me get a couple of things out of my system... "Holy Crap it's March 17th already" and "Holy Crap, we're all Windows Phone Developers!" I'm sure both of those were old news to anyone that's not been in a coma since Monday, but I've been a tad busy here at #MIX10. I'm not complainin' ... I'm just sayin' From SilverlightCream.com: Getting Started with Silverlight and Windows Phone 7 Development With any new Silverlight technology we have to begin with Tim Heuer... and this is Tim's announcement of Silverlight on the Windows Phone 7 Series ('cmon, can I call it a "Silverlight Phone"? ... please?) ... hope I didn't type that out loud :) ... so... in case you fell asleep Sunday, and just woke up, Tim let the dogs out on this and we could all talk about it. In all seriousness, bookmark this page... lots of good links. A guide to what has changed in the Silverlight 4 RC Continuing the 'bookmark this page' thought... Tim Heuer also has one up on what the heck is all in the Silverlight 4 RC they released on Monday... check this out... really good stuff in there... and a great post detailing it all. The Silverlight 4 Release Candidate René Schulte has a good post up detailing the new stuff in Silverlight 4 RC, with special attention paid to the webcam/mic and AsyncCaptureImage Let it ring - WriteableBitmapEx for Windows Phone René Schulte has a Windows Phone post up as well, introducing the WriteableBitmapEx library for Windows Phone... how cool is that?? Silverlight for Windows Phone 7 is NOT the same full Silverlight 3 RTM Bart Czernicki dug into the docs to expose some of the differences between Silverlight for the Windows Phone and Silverlight 3. If you've been developing in SL3 and want to also do Phone, check out this post and his resource listings. Trying to sketch a Windows Phone 7 application Mark Monster tried to SketchFlow a Windows Phone app and hit some problems... if anyone has thoughts, contribute on his blog page. Using Reactive Extensions in Silverlight – part 2 – Web Services Pencho Popadiyn has part 2 of his tutorial on Rx, and this one is concentrating on asynchronous service calls. Silverlight 4 Quick Tip: Out-Of-Browser Improvements This post from Alex Golesh is a little weird since he was sitting next to me in a session at MIX10 when he submitted it :) ... good update on what's new in OOB in the RC Turning a round button into a rounded panel I like Phil Middlemiss' other title for this post: "A Scalable Orb Panel-Button-Thingy" ... this is a very cool resizing button that works amazingly similar to the resizable skinned dialogs I did in Win32!... very cool, Phil! Go Get It – The Windows Phone Developer Training Kit Did you know there was a Windows Phone Training Kit with Hands-on Labs? Yochay Kiriaty at the Windows Phone Developer Blog wrote about it...

• Localization with ASP.NET MVC ModelMetadata

  - by kazimanzurrashid

  When using the DisplayFor/EditorFor there has been built-in support in ASP.NET MVC to show localized validation messages, but no support to show the associate label in localized text, unless you are using the .NET 4.0 with Mvc Future. Lets a say you are creating a create form for Product where you have support both English and German like the following. English German I have recently added few helpers for localization in the MvcExtensions, lets see how we can use it to localize the form. As mentioned in the past that I am not a big fan when it comes to decorate class with attributes which is the recommended way in ASP.NET MVC. Instead, we will use the fluent configuration (Similar to FluentNHibernate or EF CodeFirst) of MvcExtensions to configure our View Models. For example for the above we will using: public class ProductEditModelConfiguration : ModelMetadataConfiguration<ProductEditModel> { public ProductEditModelConfiguration() { Configure(model => model.Id).Hide(); Configure(model => model.Name).DisplayName(() => LocalizedTexts.Name) .Required(() => LocalizedTexts.NameCannotBeBlank) .MaximumLength(64, () => LocalizedTexts.NameCannotBeMoreThanSixtyFourCharacters); Configure(model => model.Category).DisplayName(() => LocalizedTexts.Category) .Required(() => LocalizedTexts.CategoryMustBeSelected) .AsDropDownList("categories", () => LocalizedTexts.SelectCategory); Configure(model => model.Supplier).DisplayName(() => LocalizedTexts.Supplier) .Required(() => LocalizedTexts.SupplierMustBeSelected) .AsListBox("suppliers"); Configure(model => model.Price).DisplayName(() => LocalizedTexts.Price) .FormatAsCurrency() .Required(() => LocalizedTexts.PriceCannotBeBlank) .Range(10.00m, 1000.00m, () => LocalizedTexts.PriceMustBeBetweenTenToThousand); } } As you can we are using Func<string> to set the localized text, this is just an overload with the regular string method. There are few more methods in the ModelMetadata which accepts this Func<string> where localization can applied like Description, Watermark, ShortDisplayName etc. The LocalizedTexts is just a regular resource, we have both English and German:   Now lets see the view markup: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Demo.Web.ProductEditModel>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> <%= LocalizedTexts.Create %> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= LocalizedTexts.Create %></h2> <%= Html.ValidationSummary(false, LocalizedTexts.CreateValidationSummary)%> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <fieldset> <%= Html.EditorForModel() %> <p> <input type="submit" value="<%= LocalizedTexts.Create %>" /> </p> </fieldset> <% } %> <div> <%= Html.ActionLink(LocalizedTexts.BackToList, "Index")%> </div> </asp:Content> As we can see that we are using the same LocalizedTexts for the other parts of the view which is not included in the ModelMetadata like the Page title, button text etc. We are also using EditorForModel instead of EditorFor for individual field and both are supported. One of the added benefit of the fluent syntax based configuration is that we will get full compile type checking for our resource as we are not depending upon the string based resource name like the ASP.NET MVC. You will find the complete localized CRUD example in the MvcExtensions sample folder. That’s it for today.

• Install Problem (Ubuntu Server 10.04) with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option! Help

  - by Alastair

  We cannot seem to install Ubuntu Server with USB as it reboots when I hit 'enter' for 'Install Ubuntu Server' option. My friend wants to try setting up a server so; we downloaded Ubuntu Server 10.04.4 we created a boot CD and installed ubuntu server no problem at all. But then the problem arose the hardrive we wanted to use is a 1tb sata drive and the computer orginally has 40gb IDE. So I bought a Sata to IDE and IDE to Sata converter from: http://www.microdirect.co.uk/Home/Product/52926/IDE-to-SATA-converter---Converts-IDE-HDD-to-SATA-inc-sata-data-and-power-cables Unfortunately this converter means I cannot plug in the IDE cable meaning I only have one IDE connection i.e CD drive has to be disconnected for the 1tb sata Hardrive to be connected. So now the 1tb drive is connected, powered it on opened the bios to make sure the hdd appeared it did as ST3ASDAPFKG (somthing like that). Fortunately the computer supports USB booting, so I read ubuntu server usb install instructions I tried: Startup Disk Creator & Unebootin Startup Disk Creator made the usb bootable with the 'ubuntu-10.04.4-server-i386.iso' All looked fine stuck the usb drive in, booted the machine up and I am quickly presented with ubuntu language choice. I hit enter to select English then I am presented with: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system I can move up and down the menu fine everything seems ok, I select 'Install Ubuntu Server', computer just hangs and screen either goes blank or locks. So I rebooted the computer loads the same menus fine, I select 'Install Ubuntu Server' hit 'enter' and the computer just restarts then brings me back to the same menu. hmmm Then I tried choosing the rest of the options separately: Install Ubuntu Server, Install Ubuntu Enterprise Cloud, Check Disk for defects, test memory, Boot from first hard disk, Rescue a broken system computer just restarts and back to the same ubuntu menu every-time. Grrrr At this point I wish I actually new how to command line install or something but I don't have a clue how to do that. So I tried hitting 'f6' for 'other options' and I tried them all in various combinations and individually. No Luck: (Expert mode, acpi=off, noapic, nolapic, edd=on, nodmraid, nomodeset, Free Software only) At this point I am wondering if it is a bios setting causing problems, I tried turning every option in there on off that I don't understand. No Luck. I then discovered by accident if you hit esc in the ubuntu install menu it says "you are leaving the graphical boot menu and starting the text mode interface" I hit 'Ok'. Next a prompt pops up saying 'boot:' One time it responded when I typed somthing with 'Cannot find kernal image (something like that but since then it just restarts when I hit enter in that prompt). I had a browse on the net and found someone suggesting removing quiet from install command for 'Install Ubuntu Server'. Made no difference at all just reboots... Orginal boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz quiet -- Modified boot options noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/ubuntu-server.seed initrd=/install/initrd.gz -- Still I cannot install Ubuntu Server by USB as it, reboots when I hit 'enter' for 'Install Ubuntu Server' option. This is a real pain as we cannot take the 1tb Sata Hardrive and swap it for IDE to be able to use the cd drive. Why is is it so hard to install ubuntu server with usb? I have wasted a full day and half on this really frustrated any help would be amazing! I know the answers out there just seems a bit illusive at the moment!

• SQL SERVER – List of All the Samples Database Available to Download for FREE

  - by Pinal Dave

  It is pretty much very common to have a sample database for any database product. Different companies keep on improving their product and keep on coming up with innovation in their product. To demonstrate the capability of their new enhancements they need the sample database. Microsoft have various sample database available for free download for their SQL Server Product. I have collected them here in a single blog post. Download an AdventureWorks Database The AdventureWorks OLTP database supports standard online transaction processing scenarios for a fictitious bicycle manufacturer (Adventure Works Cycles). Scenarios include Manufacturing, Sales, Purchasing, Product Management, Contact Management, and Human Resources. Coconut Dal Coconut Dal is a lightweight data access layer, for use in projects where the Entity Framework cannot be used or Microsoft’s Enterprise Library Data Block is unsuitable. Anyone who is handwriting ADO.NET should use a library instead and Coconut Dal might be the answer.  DataBooster – Extension to ADO.NET Data Provider The dbParallel DataBooster library is a high-performance extension to ADO.NET Data Provider, includes two aspects: 1) A slimmed down API encapsulation which simplified the most common data access operations (DbConnection -> DbCommand -> DbParameter -> DbDataReader) into a single class DbAccess, to help application with a clean DAL, avoid over-packing and redundant-copy of data transfer. 2) A booster for writing mass data onto database. Base on a rational utilization of database concurrency and a effective utilization of network bandwidth. Tabular AMO 2012 The sample is made of two project parts. The first part is a library of functions to manage tabular models -AMO2Tabular V2-. The second part is a sample to build a tabular model -AdventureWorks Tabular AMO 2012- using the AMO2Tabular library; the created model is similar to the ‘AdventureWorks Tabular Model 2012. SQL Server Analysis Services Product Samples SQL Server Analysis Services provides, a unified and integrated view of all your business data as the foundation for all of your traditional reporting, online analytical processing (OLAP) analysis, Key Performance Indicator (KPI) scorecards, and data mining. Analysis Services Samples for SQL Server 2008 R2 This release is dedicated to the samples that ship for Microsoft SQL Server 2008R2. For many of these samples you will also need to download the AdventureWorks family of databases.

Big Data with CEP and SOA - September 25, 2012 - 14:15 Speaker: Markus Zirn, Oracle and Baz Kuthi, Avocent The "Big Data" trend is driving new kinds of IT projects that process machine-generated data. Such projects store and mine using Hadoop/ Map Reduce, but they also analyze streaming data via event-driven patterns, which can be called "Fast Data" complementary to "Big Data". This session highlights how "Big Data" and "Fast Data" design patterns can be combined with SOA design principles into modern, event-driven architectures. We will describe specific architectures that combines CEP, Distributed Caching, Event-driven Network, SOA Composites, Application Development Framework, as well as Hadoop. Architecture patterns include pre-processing and filtering event streams as close as possible to the event source, in memory master data for event pattern matching, event-driven user interfaces as well as distributed event processing. Focus is on how "Fast Data" requirements are elegantly integrated into a traditional SOA architecture. Markus Zirn is Vice President of Product Management covering Oracle SOA Suite, SOA Governance, Application Integration Architecture, BPM, BPM Solutions, Complex Event Processing and UPK, an end user learning solution. He is the author of “The BPEL Cookbook” (rated best book on Services Oriented Architecture in 2007) as well as “Fusion Middleware Patterns”. Previously, he was a management consultant with Booz Allen & Hamilton’s High Tech practice in Duesseldorf as well as San Francisco and Vice President of Product Marketing at QUIQ. Mr. Zirn holds a Masters of Electrical Engineering from the University of Karlsruhe and is an alumnus of the Tripartite program, a joint European degree from the University of Karlsruhe, Germany, the University of Southampton, UK, and ESIEE, France.

• Introducing .NET 4.0 with Visual Studio 2010 by Alex Mackey - Book review

  - by Malisa L. Ncube

  Alex (http://simpleisbest.co.uk/) does a very good job in covering the new features of .NET 4.0 and Visual Studio 2010. His focus is on the developers that have experience in development using previous versions of Visual Studio, more specifically Visual Studio 2008.     The following are my views towards his book. 1. Scope / Coverage Even as the book is labeled as introduction, it is covers a broad spectrum of technologies, features and references that are focused into helping a developer quickly decide what to use in the new .NET framework. a. Content The content included covers as much as possible the new additions that are included in the new .NET version 4.0. He shows the Visual Studio 2010 new features and quickly shows how to extend it using Managed Extensibility Framework. Some of my favorites are parallel debugging enhancements. The author delves into JQuery, which Microsoft has decided to support. Some of the very interesting content is on the out-of-band releases including ASP.NET MVC, Windows Azure Silverlight 3 and WCF Data Services. b. What is not included? Windows Phone 7 Series. This was only talked about in the MIX10. The data may not have been available at the time of writing. Microsoft Pinpoint (Microsoft code name "Dallas") Windows Embedded development. c. Table of Contents Chapter 1: Introduction Chapter 2: Visual Studio IDE and MEF Chapter 3: Language and Dynamic Changes Chapter 4: CLR and BCL Changes Chapter 5: Parallelization and Threading Enhancements Chapter 6: Windows Workflow Foundation 4 Chapter 7: Windows Communication Foundation Chapter 8: Entity Framework Chapter 9: WCF Data Services Chapter 10: ASPNET Chapter 11: Microsoft AJAX Library Chapter 12: jQuery Chapter 13: ASPNET MVC Chapter 14: Silverlight Introduction Chapter 15: WPF 4.0 and Silverlight 3.0 Chapter 16: Windows Azure 2. Depth Avoids getting into depth on the topics presented, to present the new concepts in assumption of the developer’s existing knowledge. Code samples are on book and exist mostly as snippets and very easy to follow. There are no downloadable examples. 3. Complexity The book is written in a very simple way and easy to follow. There are no irrelevant intimidating details. So it’s a book that you can grab and never put down until you’ve finished reading the entire book. 4. References The author includes reference links to blogs, Wikis and a lot of online resources including the MSDN documentation, which is a very convenient strategy to avoid flooding the reader with details which may not be of interest to them. Most sites do not use url routing and that is really not nice. There are notes from interviews between the author and people behind the new technologies, in which they explain what some specific areas that need clarifications and what their future views are in relation to the features they are working on. 5. Target The author targets experts that want to make a transition from .NET 3.5 to 4.0. Some obvious 3.5 features have been purposely excluded from the text 6. Overrall It is evident that the author has made extensive research into the breadth of what MS is working on, in relation to .NET and Visual Studio and has also been watching the online community. What I would like to see in the next edition are some details on OData protocol, Expression Blend 4 and Embedded development and Windows Phone development. I should say I’m one of the beneficiaries of this book. Excellent work Alex.   Technorati Tags: .NET,Book-Review,Visual Studio
