• SQLAuthority News – Learning Never Ends – Becoming Student Again

  - by pinaldave

  From my past few blog posts you may see a pattern – learning.  I finished my own college education a few years ago, but I firmly believe that learning should never stop.  We can learn on the job, or from outside reading, but we should always try to be learning new things.  It keeps the brain sharp!  In fact, I often find myself learning new things from reviewing old material.  If you have been reading my blog lately, you will recognize the name Koenig Solutions. You might also be rolling your eyes at me and my enthusiasm for learning and training.  College was hard work, why continue it?  Didn’t we all get educations so that we could get jobs and go on vacation? Of course, having a job means that you cannot take vacations all the time.  I have often asked my friend who owns Koenig, jokingly, when he is going to open a Koenig center in Bangalore. I relocated to Bangalore 1.5 years ago, so I wanted a center I could walk to anytime.  Last week I was very happy to hear that they have opened a center in Bangalore. Pinal Dave at Friend’s Company I could not let a new center open without visiting it and congratulating my friend, so I recently stopped by.  I was immediately taken by the desire to go back to “school” and learn something new.  I have signed up to take a continuing education course through the new Koenig center and here is the exciting part: I will be blogging about it so that you all can be inspired to learn, too!  Keep checking back here for further updates and blog posts about my learning experience. However, what is the fun to attend the session in the town where you stay. I indeed visited their center in Bangalore but I have opted to learn the course in another city. Well, more information about the same in near future. Pinal Dave is going to be a student again Honestly, why not learn new things and become more confident?  When we have more education we will become better at our jobs, which can lead to more confidence and efficiency, but may also have more physical rewards – like a raise or promotion.  We don’t always have to focus on shallow rewards like money and recognition, so think about how much more you will enjoy your work when you know more about it.  Koenig is offering training for new certificates in SQL Server 2012, and I am planning on investigating these for sure. I feel good that I am going to be a student again and will be learning new stuff. As I said I will blog my experience as I go. I hope that my continuing education blog posts will inspire you, my readers, to go out and learn more.  I am serious about my education and my goal is to prove how serious I am here, on my blog. I am a big fan of Learning and Sharing and I hope this series will inspire you to learn new technology which can help you progress in your career and help balance your life with work. Note: This blog post is about what inspired me to sign up for learning course. Becoming student should be the attitude of a lifetime. This post is not about a career change.

• Get to Know a Candidate (9 of 25): Gary Johnson&ndash;Libertarian Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Johnson served as the 29th Governor of New Mexico from 1995 to 2003, as a member of the Republican Party, and is known for his low-tax libertarian views and his strong emphasis on personal health and fitness. While a student at the University of New Mexico in 1974, Johnson sustained himself financially by working as a door-to-door handyman. In 1976 he founded Big J Enterprises, which grew from this one-person venture to become one of New Mexico's largest construction companies. He entered politics for the first time by running for Governor of New Mexico in 1994 on a fiscally conservative, low-tax, anti-crime platform. Johnson won the Republican Party of New Mexico's gubernatorial nomination, and defeated incumbent Democratic governor Bruce King by 50% to 40%. He cut the 10% annual growth in the budget: in part, due to his use of the gubernatorial veto 200 times during his first six months in office, which gained him the nickname "Governor Veto". Johnson sought re-election in 1998, winning by 55% to 45%. In his second term, he concentrated on the issue of school voucher reforms, as well as campaigning for marijuana decriminalization and opposition to the War on Drugs. During his tenure as governor, Johnson adhered to a stringent anti-tax and anti-bureaucracy policy driven by a cost–benefit analysis rationale, setting state and national records for his use of veto powers: more than the other 49 contemporary governors put together. Term-limited, Johnson could not run for re-election at the end of his second term. As a fitness enthusiast, Johnson has taken part in several Ironman Triathlons, and he climbed Mount Everest in May 2003. After leaving office, Johnson founded the non-profit Our America Initiative in 2009, a political advocacy committee seeking to promote policies such as free enterprise, foreign non-interventionism, limited government and privatization. The Libertarian Party is the third largest political party in the United States. It is also identified by many as the fastest growing political party in the United States. The political platform of the Libertarian Party reflects the ideas of libertarianism, favoring minimally regulated markets, a less powerful state, strong civil liberties (including support for Same-sex marriage and other LGBT rights), cannabis legalization and regulation, separation of church and state, open immigration, non-interventionism and neutrality in diplomatic relations (i.e., avoiding foreign military or economic entanglements with other nations), freedom of trade and travel to all foreign countries, and a more responsive and direct democracy. Members of the Libertarian Party have also supported the repeal of NAFTA, CAFTA, and similar trade agreements, as well as the United States' exit from the United Nations, WTO, and NATO. Although there is not an officially labeled political position of the party, it is considered by many to be more right-wing than the Democratic Party but more left-wing than the Republican Party when comparing the parties' positions to each other, placing it at or above the center. In the 30 states where voters can register by party, there are over 282,000 voters registered as Libertarians. Hundreds of Libertarian candidates have been elected or appointed to public office, and thousands have run for office under the Libertarian banner. The Libertarian Party has many firsts in its credit, such as being the first party to get an electoral vote for a woman in a United States presidential election. Learn more about Gary Johnson and Libertarian Party on Wikipedia.

• HTML5 point and click adventure game code structure with CreateJS

  - by user1612686

  I'm a programming beginner. I made a tiny one scene point and click adventure game to try to understand simple game logic and came up with this: CreateJS features prototypes for creating bitmap images, sprites and sounds objects. I create them and define their properties in a corresponding function (for example images(); spritesheets(), sounds()...). I then create functions for each animation sequence and "game level" functions, which handle user interactions and play the according animations and sounds for a certain event (when the level is complete, the current level function calls the next level function). And I end up with quite the mess. What would be the "standard (if something like that exists)" OOP approach to structure simple game data and interactions like that? I thought about making game.images, game.sprites, game.sounds objects, which contain all the game data with its properties using CreateJS constructors. game.spriteAnimations and game.tweenAnimations objects for sprite animations and tweens and a game.levelN object, which communicates with a game.interaction object, processing user interaction. Does this make any sense? How do you structure your simple game code? Thanks in advance!

• Can I migrate from GNU Mailman to MailChimp?

  - by Flowpoke

  I have ~20 lists, all of which are mostly announce-only (newsletters--recipients do not reply back to the list) running in GNU Mailman. It's alright. Mailman has certainly prooven itself but we want some progressive features and a better peice of mind (delivery success, hosting, etc... we'd be happy paying a 3rd party to handle these things). can MailChimp give us what we need? I see tons of fun copy and graphics, showing off neat features but what I really want to do is; if MailChimp is doing the mailings, what does the address look like? is MailChimp good for sending out simple newsletters? What about automatic bounce processing / unsubscribing of users? I setup a free account but I don't see how any of it integrates into my own domain... no DNS overrides or cname suggestions. Also, I see MailChimp has a clean and nifty API client in Python that I want to integrate into our sites (Django powered) so that really really makes the service attractive to me--I just hope I understand it correctly.

Question of the Day: Which of the following queries will return dirty data? a) SELECT * FROM Table1 (READUNCOMMITED) b) SELECT * FROM Table1 (NOLOCK) c) SELECT * FROM Table1 (DIRTYREAD) d) SELECT * FROM Table1 (MYLOCK) Query Hints: BIG HINT POST Most SQL people know what a “Dirty Record” is. You might also call that an “Intermediate record”. In case this is new to you here is a very quick explanation. The simplest way to describe the steps of a transaction is to use an example of updating an existing record into a table. When the insert runs, SQL Server gets the data from storage, such as a hard drive, and loads it into memory and your CPU. The data in memory is changed and then saved to the storage device. Finally, a message is sent confirming the rows that were affected. For a very short period of time the update takes the data and puts it into memory (an intermediate state), not a permanent state. For every data change to a table there is a brief moment where the change is made in the intermediate state, but is not committed. During this time, any other DML statement needing that data waits until the lock is released. This is a safety feature so that SQL Server evaluates only official data. For every data change to a table there is a brief moment where the change is made in this intermediate state, but is not committed. During this time, any other DML statement (SELECT, INSERT, DELETE, UPDATE) needing that data must wait until the lock is released. This is a safety feature put in place so that SQL Server evaluates only official data. Additional Hints: I have previously discussed various concepts from SQL Server Joes 2 Pros Volume 1.

• Talking JavaOne with Rock Star Raghavan Srinivas

  - by Janice J. Heiss

  Raghavan Srinivas, affectionately known as “Rags,” is a two-time JavaOne Rock Star (from 2005 and 2011) who, as a Developer Advocate at Couchbase, gets his hands dirty with emerging technology directions and trends. His general focus is on distributed systems, with a specialization in cloud computing. He worked on Hadoop and HBase during its early stages, has spoken at conferences world-wide on a variety of technical topics, conducted and organized Hands-on Labs and taught graduate classes.He has 20 years of hands-on software development and over 10 years of architecture and technology evangelism experience and has worked for Digital Equipment Corporation, Sun Microsystems, Intuit and Accenture. He has evangelized and influenced the architecture of numerous technologies including the early releases of JavaFX, Java, Java EE, Java and XML, Java ME, AJAX and Web 2.0, and Java Security.Rags will be giving these sessions at JavaOne 2012: CON3570 -- Autosharding Enterprise to Social Gaming Applications with NoSQL and Couchbase CON3257 -- Script Bowl 2012: The Battle of the JVM-Based Languages (with Guillaume Laforge, Aaron Bedra, Dick Wall, and Dr Nic Williams) Rags emphasized the importance of the Cloud: “The Cloud and the Big Data are popular technologies not merely because they are trendy, but, largely due to the fact that it's possible to do massive data mining and use that information for business advantage,” he explained. I asked him what we should know about Hadoop. “Hadoop,” he remarked, “is mainly about using commodity hardware and achieving unprecedented scalability. At the heart of all this is the Java Virtual Machine which is running on each of these nodes. The vision of taking the processing to where the data resides is made possible by Java and Hadoop.” And the most exciting thing happening in the world of Java today? “I read recently that Java projects on github.com are just off the charts when compared to other projects. It's exciting to realize the robust growth of Java and the degree of collaboration amongst Java programmers.” He encourages Java developers to take advantage of Java 7 for Mac OS X which is now available for download. At the same time, he also encourages us to read the caveats. Originally published on blogs.oracle.com/javaone.

• SQL SERVER – Introduction to LEAD and LAG – Analytic Functions Introduced in SQL Server 2012

  - by pinaldave

  SQL Server 2012 introduces new analytical function LEAD() and LAG(). This functions accesses data from a subsequent row (for lead) and previous row (for lag) in the same result set without the use of a self-join . It will be very difficult to explain this in words so I will attempt small example to explain you this function. Instead of creating new table, I will be using AdventureWorks sample database as most of the developer uses that for experiment. Let us fun following query. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, LEAD(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID ) LeadValue, LAG(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID ) LagValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO Above query will give us following result. When we look at above resultset it is very clear that LEAD function gives us value which is going to come in next line and LAG function gives us value which was encountered in previous line. If we have to generate the same result without using this function we will have to use self join. In future blog post we will see the same. Let us explore this function a bit more. This function not only provide previous or next line but it can also access any line before or after using offset. Let us fun following query, where LEAD and LAG function accesses the row with offset of 2. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, LEAD(SalesOrderDetailID,2) OVER (ORDER BY SalesOrderDetailID ) LeadValue, LAG(SalesOrderDetailID,2) OVER (ORDER BY SalesOrderDetailID ) LagValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO Above query will give us following result. You can see the LEAD and LAG functions  now have interval of  rows when they are returning results. As there is interval of two rows the first two rows in LEAD function and last two rows in LAG function will return NULL value. You can easily replace this NULL Value with any other default value by passing third parameter in LEAD and LAG function. Let us fun following query. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, LEAD(SalesOrderDetailID,2,0) OVER (ORDER BY SalesOrderDetailID ) LeadValue, LAG(SalesOrderDetailID,2,0) OVER (ORDER BY SalesOrderDetailID ) LagValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO Above query will give us following result, where NULL are now replaced with value 0. Just like any other analytic function we can easily partition this function as well. Let us see the use of PARTITION BY in this clause. USE AdventureWorks GO SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty, LEAD(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID ) LeadValue, LAG(SalesOrderDetailID) OVER (PARTITION BY SalesOrderID ORDER BY SalesOrderDetailID ) LagValue FROM Sales.SalesOrderDetail s WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty GO Above query will give us following result, where now the data is partitioned by SalesOrderID and LEAD and LAG functions are returning the appropriate result in that window. As now there are smaller partition in my query, you will see higher presence of NULL. In future blog post we will see how this functions are compared to SELF JOIN.

• Tuxedo Runtime for CICS and Batch Webcast

  - by Jason Williamson

  There was a recent webcast about the new Tux ART solution that we released last month. Here is the link to hear Hassan talk about that Link to Listen to Webcast Below is the market speak about what the webcast is about and what you will hear. From my own experience, there is certainly an uptick in rehosting discussions and projects with customers all around the world. The notion that mainframes can be rehosted on open system is pretty well accepted. There are still some hold out CxO's who don't believe it, but those guys typically are not really looking to migrate anyway and don't take an honest look at the case studies, history and TPC reports. Maybe in my next blog I'll talk about "myth busters" -- to borrow some presentation details from Mark Rakhmilevich (Tuxedo PM for Rehosting). *********** Mainframe rehosting is a compelling approach for migrating and modernizing mainframe applications and data to lower data center cost and risk while increasing business agility. Oracle Tuxedo 11g with CICS application runtime (ART) capabilities is designed to facilitate the migration of IBM mainframe applications by allowing these to run on open systems in a distributed grid architecture. The brand new Oracle Tuxedo Application Runtime for CICS and Batch 11g can significantly reduce your costs and risks while preserving your investments in applications and data. In this on-demand Webcast, hear from Oracle Senior Vice President, Hasan Rizvi, on how Oracle Tuxedo 11g with CICS application runtime capabilities is changing the way customers think about mainframe migration. You'll learn: * What market forces drive mainframe migration and modernization * What technologies and capabilities are available for migrating mainframe transaction processing and batch applications * How Oracle brings rehosting technologies to a new level of scalability, robustness, and automation

• SQL SERVER – Basic Calculation and PEMDAS Order of Operation

  - by pinaldave

  After thinking a long time, I have decided to write about this blog post. I had no plan to create a blog post about this subject but the amount of conversation this one has created on my Facebook page, I decided to bring up a few of the question and concerns discussed on the Facebook page. There are more than 10,000 comments here so far. There are lots of discussion about what should be the answer. Well, as far as I can tell there is a big debate going on on Facebook, for educational purpose you should go ahead and read some of the comments. They are very interesting and for sure teach some new stuff. Even though some of the comments are clearly wrong they have made some good points and I believe it for sure develops some logic. Here is my take on this subject. I believe the answer is 9 as I follow PEMDAS  Order of Operation. PEMDAS stands for  parentheses, exponents, multiplication, division, addition, subtraction. PEMDAS is commonly known as BODMAS in India. BODMAS stands for Brackets, Orders (ie Powers and Square Roots, etc), Division, Multiplication,  Addition and Subtraction. PEMDAS and BODMAS are almost same and both of them follow the operation order from LEFT to RIGHT. Let us try to simplify above statement using the PEMDAS or BODMAS (whatever you prefer to call). Step 1: 6 ÷ 2 (1+2) (parentheses first) Step 2: = 6 ÷ 2 * (1+2) (adding multiplication sign for further clarification) Step 3: = 6 ÷ 2* (3) (single digit in parentheses – simplify using operator) Step 4: = 6 ÷ 2 * 3 (Remember next Operation should be LEFT to RIGHT) Step 5: = 3 * 3 (because 6 ÷ 2 = 3; remember LEFT to RIGHT) Step 6: = 9 (final answer) Some often find Step 4 confusing and often ended up multiplying 2 and 3 resulting Step 5 to be 6 ÷ 6, this is incorrect because in this case we did not follow the order of LEFT to RIGHT. When we do not follow the order of operation from LEFT to RIGHT we end up with the answer 1 which is incorrect. Let us see what SQL Server returns as a result. I executed following statement in SQL Server Management Studio SELECT 6/2*(1+2) It is clear that SQL Server also thinks that the answer should be 9. Let us go ahead and ask Google what will be the answer of above question in Google I have searched for the following term: 6/2(1+2) The result also says the answer should be 9. If you want a further reference here is a great video which describes why the answer should be 9 and not 1. And here is a fantastic conversation on Google Groups. Well, now what is your take on this subject? You are welcome to share constructive feedback and your answer may be different from my answer. NOTE: A healthy conversation about this subject is indeed encouraged but if there is a single bad word or comment is flaming it will be deleted without any notification (it does not matter how valuable information it contains).

• when to introduce an application services tier in an n-tier application

  - by user20358

  I am developing a web based application whose primary objective is to fetch data from the database, display it on the UI, take in user inputs and write them back to the database. The application is not going to be doing any industrial strength algorithm crunching, but will be receiving a very high number of hits at peak times (described below) which will be changing thru the day. The layers are your typical Presentation, Business, Data. The data layer is taken care of by the database server. The business layer will contain the DAL component to access the database server over tcp. The choices I have to separate these layers into tiers are: The presentation and business layers can be either kept on the same tier. The presentation layer on a separate tier by itself and the business layer on a separate tier by itself. In the case of choice 2, the business layer will be accessed by the presentation layer using a WCF service either over http or tcp. I don't see any heavy processing being done on the Business layer, so I am leaning towards option 1 above. I also feel for the same reason, adding a new tier will only introduce the network latency. However, in terms of scalability in case I need to scale up or scale out, which is a better way to go? This application will need to be able to support up to 6 million users an hour. There will be a reasonable amount of data in each user session, storing user's preferences and other details. I will be using page level caching as well.

• Visual Studio Exceptions dialogs

  - by Daniel Moth

  Previously I covered step 1 of live debugging with start and attach. Once the debugger is attached, you want to go to step 2 of live debugging, which is to break. One way to break under the debugger is to do nothing, and just wait for an exception to occur in your code. This is true for all types of code that you debug in Visual Studio, and let's consider the following piece of C# code:3: static void Main() 4: { 5: try 6: { 7: int i = 0; 8: int r = 5 / i; 9: } 10: catch (System.DivideByZeroException) {/*gulp. sue me.*/} 11: System.Console.ReadLine(); 12: } If you run this under the debugger do you expect an exception on line 8? It is a trick question: you have to know whether I have configured the debugger to break when exceptions are thrown (first-chance exceptions) or only when they are unhandled. The place you do that is in the Exceptions dialog which is accessible from the Debug->Exceptions menu and on my installation looks like this: Note that I have checked all CLR exceptions. I could have expanded (like shown for the C++ case in my screenshot) and selected specific exceptions. To read more about this dialog, please read the corresponding Exception Handling debugging msdn topic and all its subtopics. So, for the code above, the debugger will break execution due to the thrown exception (exactly as if the try..catch was not there), so I see the following Exception Thrown dialog: Note the following: I can hit continue (or hit break and then later continue) and the program will continue fine since I have a catch handler. If this was an unhandled exception, then that is what the dialog would say (instead of first chance exception) and continuing would crash the app. That hyperlinked text ("Open Exception Settings") opens the Exceptions dialog I described further up. The coolest thing to note is the checkbox - this is new in this latest release of Visual Studio: it is a shortcut to the checkbox in the Exceptions dialog, so you don't have to open it to change this setting for this specific exception - you can toggle that option right from this dialog. Finally, if you try the code above on your system, you may observe a couple of differences from my screenshots. The first is that you may have an additional column of checkboxes in the Exceptions dialog. The second is that the last dialog I shared may look different to you. It all depends on the Debug->Options settings, and the two relevant settings are in this screenshot: The Exception assistant is what configures the look of the UI when the debugger wants to indicate exception to you, and the Just My Code setting controls the extra column in the Exception dialog. You can read more about those options on MSDN: How to break on User-Unhandled exceptions (plus Gregg’s post) and Exception Assistant. Before I leave you to go play with this stuff a bit more, please note that this level of debugging is now available for JavaScript too, and if you are looking at the Exceptions dialog and wondering what the "GPU Memory Access Exceptions" node is about, stay tuned on the C++ AMP blog ;-) Comments about this post by Daniel Moth welcome at the original blog.

• DevDays ‘00 The Netherlands day #2

  - by erwin21

  Day 2 of DevDays 2010 and again 5 interesting sessions at the World Forum in The Hague. The first session of the today in the big world forum theater was from Scott Hanselman, he gives a lap around .NET 4.0. In his way of presenting he talked about all kind of new features of .NET 4.0 like MEF, threading, parallel processing, changes and additions to the CLR and DLR, WPF and all new language features of .NET 4.0. After a small break it was ready for session 2 from Scott Allen about Tips, Tricks and Optimizations of LINQ. He talked about lazy and deferred executions, the difference between IQueryable and IEnumerable and the two flavors of LINQ syntax. The lunch was again very good prepared and delicious, but after that it was time for session 3 Web Vulnerabilities and Exploits from Alex Thissen. This was no normal session but more like a workshop, we decided what kind of subjects we discussed, the subjects where OWASP, XSS and other injections, validation, encoding. He gave some handy tips and tricks how to prevent such attacks. Session 4 was about the new features of C# 4.0 from Alex van Beek. He talked about Optional- en Named Parameters, Generic Co- en Contra Variance, Dynamic keyword and COM Interop features. He showed how to use them but also when not to use them. The last session of today and also the last session of DevDays 2010 was about WCF Best Practices from Gerben van Loon. He talked about 7 best practices that you must know when you are going to use WCF. With some quick demos he showed the problem and the solution for some common issues. It where two interesting days and next year i sure will be attending again.

• Fake It Easy On Yourself

  - by Lee Brandt

  I have been using Rhino.Mocks pretty much since I started being a mockist-type tester. I have been very happy with it for the most part, but a year or so ago, I got a glimpse of some tests using Moq. I thought the little bit I saw was very compelling. For a long time, I had been using: 1: var _repository = MockRepository.GenerateMock<IRepository>(); 2: _repository.Expect(repo=>repo.SomeCall()).Return(SomeValue); 3: var _controller = new SomeKindaController(_repository); 4:  5: ... some exercising code 6: _repository.AssertWasCalled(repo => repo.SomeCall()); I was happy with that syntax. I didn’t go looking for something else, but what I saw was: 1: var _repository = new Mock(); And I thought, “That looks really nice!” The code was very expressive and easier to read that the Rhino.Mocks syntax. I have gotten so used to the Rhino.Mocks syntax that it made complete sense to me, but to developers I was mentoring in mocking, it was sometimes to obtuse. SO I thought I would write some tests using Moq as my mocking tool. But I discovered something ugly once I got into it. The way Mocks are created makes Moq very easy to read, but that only gives you a Mock not the object itself, which is what you’ll need to pass to the exercising code. So this is what it ends up looking like: 1: var _repository = new Mock<IRepository>(); 2: _repository.SetUp(repo=>repo.SomeCall).Returns(SomeValue); 3: var _controller = new SomeKindaController(_repository.Object); 4: .. some exercizing code 5: _repository.Verify(repo => repo.SomeCall()); Two things jump out at me: 1) when I set up my mocked calls, do I set it on the Mock or the Mock’s “object”? and 2) What am I verifying on SomeCall? Just that it was called? that it is available to call? Dealing with 2 objects, a “Mock” and an “Object” made me have to consider naming conventions. Should I always call the mock _repositoryMock and the object _repository? So I went back to Rhino.Mocks. It is the most widely used framework, and show other how to use it is easier because there is one natural object to use, the _repository. Then I came across a blog post from Patrik Hägne, and that led me to a post about FakeItEasy. I went to the Google Code site and when I saw the syntax, I got very excited. Then I read the wiki page where Patrik stated why he wrote FakeItEasy, and it mirrored my own experience. So I began to play with it a bit. So far, I am sold. the syntax is VERY easy to read and the fluent interface is super discoverable. It basically looks like this: 1: var _repository = A.Fake<IRepository>(); 2: a.CallTo(repo=>repo.SomeMethod()).Returns(SomeValue); 3: var _controller = new SomeKindaController(_repository); 4: ... some exercising code 5: A.CallTo(() => _repository.SOmeMethod()).MustHaveHappened(); Very nice. But is it mature? It’s only been around a couple of years, so will I be giving up some thing that I use a lot because it hasn’t been implemented yet? I doesn’t seem so. As I read more examples and posts from Patrik, he has some pretty complex scenarios. He even has support for VB.NET! So if you are looking for a mocking framework that looks and feels very natural, try out FakeItEasy!

• MvcExtensions - ActionFilter

  - by kazimanzurrashid

  One of the thing that people often complains is dependency injection in Action Filters. Since the standard way of applying action filters is to either decorate the Controller or the Action methods, there is no way you can inject dependencies in the action filter constructors. There are quite a few posts on this subject, which shows the property injection with a custom action invoker, but all of them suffers from the same small bug (you will find the BuildUp is called more than once if the filter implements multiple interface e.g. both IActionFilter and IResultFilter). The MvcExtensions supports both property injection as well as fluent filter configuration api. There are a number of benefits of this fluent filter configuration api over the regular attribute based filter decoration. You can pass your dependencies in the constructor rather than property. Lets say, you want to create an action filter which will update the User Last Activity Date, you can create a filter like the following: public class UpdateUserLastActivityAttribute : FilterAttribute, IResultFilter { public UpdateUserLastActivityAttribute(IUserService userService) { Check.Argument.IsNotNull(userService, "userService"); UserService = userService; } public IUserService UserService { get; private set; } public void OnResultExecuting(ResultExecutingContext filterContext) { // Do nothing, just sleep. } public void OnResultExecuted(ResultExecutedContext filterContext) { Check.Argument.IsNotNull(filterContext, "filterContext"); string userName = filterContext.HttpContext.User.Identity.IsAuthenticated ? filterContext.HttpContext.User.Identity.Name : null; if (!string.IsNullOrEmpty(userName)) { UserService.UpdateLastActivity(userName); } } } As you can see, it is nothing different than a regular filter except that we are passing the dependency in the constructor. Next, we have to configure this filter for which Controller/Action methods will execute: public class ConfigureFilters : ConfigureFiltersBase { protected override void Configure(IFilterRegistry registry) { registry.Register<HomeController, UpdateUserLastActivityAttribute>(); } } You can register more than one filter for the same Controller/Action Methods: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(); You can register the filters for a specific Action method instead of the whole controller: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(c => c.Index()); You can even set various properties of the filter: registry.Register<ControlPanelController, CustomAuthorizeAttribute>( attribute => { attribute.AllowedRole = Role.Administrator; }); The Fluent Filter registration also reduces the number of base controllers in your application. It is very common that we create a base controller and decorate it with action filters and then we create concrete controller(s) so that the base controllers action filters are also executed in the concrete controller. You can do the  same with a single line statement with the fluent filter registration: Registering the Filters for All Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type))); Registering Filters for selected Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type) && (type.Name.StartsWith("Home") || type.Name.StartsWith("Post")))); You can also use the built-in filters in the fluent registration, for example: registry.Register<HomeController, OutputCacheAttribute>(attribute => { attribute.Duration = 60; }); With the fluent filter configuration you can even apply filters to controllers that source code is not available to you (may be the controller is a part of a third part component). That’s it for today, in the next post we will discuss about the Model binding support in MvcExtensions. So stay tuned.

• SQLAuthority News – Scaling Up Your Data Warehouse with SQL Server 2008 R2

  - by pinaldave

  Data Warehouses are suppose to be containing huge amount of the data from the beginning. However, there are cases when too big is not enough. Every Data Warehouse Admin will agree that they have faced situation where they will need to scale up their data warehouse. Microsoft has released white paper discussing the same. Here is the abstract from the Microsoft Official site: SQL Server 2008 introduced many new functional and performance improvements for data warehousing, and SQL Server 2008 R2 includes all these and more. This paper discusses how to use SQL Server 2008 R2 to get great performance as your data warehouse scales up. We present lessons learned during extensive internal data warehouse testing on a 64-core HP Integrity Superdome during the development of the SQL Server 2008 release, and via production experience with large-scale SQL Server customers. Our testing indicates that many customers can expect their performance to nearly double on the same hardware they are currently using, merely by upgrading to SQL Server 2008 R2 from SQL Server 2005 or earlier, and compressing their fact tables. We cover techniques to improve manageability and performance at high-scale, encompassing data loading (extract, transform, load), query processing, partitioning, index maintenance, indexed view (aggregate) management, and backup and restore.

• Big Data – Basics of Big Data Architecture – Day 4 of 21

  - by Pinal Dave

  In yesterday’s blog post we understood how Big Data evolution happened. Today we will understand basics of the Big Data Architecture. Big Data Cycle Just like every other database related applications, bit data project have its development cycle. Though three Vs (link) for sure plays an important role in deciding the architecture of the Big Data projects. Just like every other project Big Data project also goes to similar phases of the data capturing, transforming, integrating, analyzing and building actionable reporting on the top of  the data. While the process looks almost same but due to the nature of the data the architecture is often totally different. Here are few of the question which everyone should ask before going ahead with Big Data architecture. Questions to Ask How big is your total database? What is your requirement of the reporting in terms of time – real time, semi real time or at frequent interval? How important is the data availability and what is the plan for disaster recovery? What are the plans for network and physical security of the data? What platform will be the driving force behind data and what are different service level agreements for the infrastructure? This are just basic questions but based on your application and business need you should come up with the custom list of the question to ask. As I mentioned earlier this question may look quite simple but the answer will not be simple. When we are talking about Big Data implementation there are many other important aspects which we have to consider when we decide to go for the architecture. Building Blocks of Big Data Architecture It is absolutely impossible to discuss and nail down the most optimal architecture for any Big Data Solution in a single blog post, however, we can discuss the basic building blocks of big data architecture. Here is the image which I have built to explain how the building blocks of the Big Data architecture works. Above image gives good overview of how in Big Data Architecture various components are associated with each other. In Big Data various different data sources are part of the architecture hence extract, transform and integration are one of the most essential layers of the architecture. Most of the data is stored in relational as well as non relational data marts and data warehousing solutions. As per the business need various data are processed as well converted to proper reports and visualizations for end users. Just like software the hardware is almost the most important part of the Big Data Architecture. In the big data architecture hardware infrastructure is extremely important and failure over instances as well as redundant physical infrastructure is usually implemented. NoSQL in Data Management NoSQL is a very famous buzz word and it really means Not Relational SQL or Not Only SQL. This is because in Big Data Architecture the data is in any format. It can be unstructured, relational or in any other format or from any other data source. To bring all the data together relational technology is not enough, hence new tools, architecture and other algorithms are invented which takes care of all the kind of data. This is collectively called NoSQL. Tomorrow Next four days we will answer the Buzz Words – Hadoop.

• Big Data – Basics of Big Data Analytics – Day 18 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned the importance of the various components in Big Data Story. In this article we will understand what are the various analytics tasks we try to achieve with the Big Data and the list of the important tools in Big Data Story. When you have plenty of the data around you what is the first thing which comes to your mind? “What do all these data means?” Exactly – the same thought comes to my mind as well. I always wanted to know what all the data means and what meaningful information I can receive out of it. Most of the Big Data projects are built to retrieve various intelligence all this data contains within it. Let us take example of Facebook. When I look at my friends list of Facebook, I always want to ask many questions such as - On which date my maximum friends have a birthday? What is the most favorite film of my most of the friends so I can talk about it and engage them? What is the most liked placed to travel my friends? Which is the most disliked cousin for my friends in India and USA so when they travel, I do not take them there. There are many more questions I can think of. This illustrates that how important it is to have analysis of Big Data. Here are few of the kind of analysis listed which you can use with Big Data. Slicing and Dicing: This means breaking down your data into smaller set and understanding them one set at a time. This also helps to present various information in a variety of different user digestible ways. For example if you have data related to movies, you can use different slide and dice data in various formats like actors, movie length etc. Real Time Monitoring: This is very crucial in social media when there are any events happening and you wanted to measure the impact at the time when the event is happening. For example, if you are using twitter when there is a football match, you can watch what fans are talking about football match on twitter when the event is happening. Anomaly Predication and Modeling: If the business is running normal it is alright but if there are signs of trouble, everyone wants to know them early on the hand. Big Data analysis of various patterns can be very much helpful to predict future. Though it may not be always accurate but certain hints and signals can be very helpful. For example, lots of data can help conclude that if there is lots of rain it can increase the sell of umbrella. Text and Unstructured Data Analysis: unstructured data are now getting norm in the new world and they are a big part of the Big Data revolution. It is very important that we Extract, Transform and Load the unstructured data and make meaningful data out of it. For example, analysis of lots of images, one can predict that people like to use certain colors in certain months in their cloths. Big Data Analytics Solutions There are many different Big Data Analystics Solutions out in the market. It is impossible to list all of them so I will list a few of them over here. Tableau – This has to be one of the most popular visualization tools out in the big data market. SAS – A high performance analytics and infrastructure company IBM and Oracle – They have a range of tools for Big Data Analysis Tomorrow In tomorrow’s blog post we will discuss about very important components of the Big Data Ecosystem – Data Scientist.
