Automating XNA Performance Testing?

- by Grofit

I was wondering what peoples approaches or thoughts were on automating performance testing in XNA. Currently I am looking at only working in 2d, but that poses many areas where performance can be improved with different implementations. An example would be if you had 2 different implementations of spatial partitioning, one may be faster than another but without doing some actual performance testing you wouldn't be able to tell which one for sure (unless you saw the code was blatantly slow in certain parts). You could write a unit test which for a given time frame kept adding/updating/removing entities for both implementations and see how many were made in each timeframe and the higher one would be the faster one (in this given example). Another higher level example would be if you wanted to see how many entities you can have on the screen roughly without going beneath 60fps. The problem with this is to automate it you would need to use the hidden form trick or some other thing to kick off a mock game and purely test which parts you care about and disable everything else. I know that this isnt a simple affair really as even if you can automate the tests, really it is up to a human to interpret if the results are performant enough, but as part of a build step you could have it run these tests and publish the results somewhere for comparison. This way if you go from version 1.1 to 1.2 but have changed a few underlying algorithms you may notice that generally the performance score would have gone up, meaning you have improved your overall performance of the application, and then from 1.2 to 1.3 you may notice that you have then dropped overall performance a bit. So has anyone automated this sort of thing in their projects, and if so how do you measure your performance comparisons at a high level and what frameworks do you use to test? As providing you have written your code so its testable/mockable for most parts you can just use your tests as a mechanism for getting some performance results... === Edit === Just for clarity, I am more interested in the best way to make use of automated tests within XNA to track your performance, not play testing or guessing by manually running your game on a machine. This is completely different to seeing if your game is playable on X hardware, it is more about tracking the change in performance as your game engine/framework changes. As mentioned in one of the comments you could easily test "how many nodes can I insert/remove/update within QuadTreeA within 2 seconds", but you have to physically look at these results every time to see if it has changed, which may be fine and is still better than just relying on playing it to see if you notice any difference between version. However if you were to put an Assert in to notify you of a fail if it goes lower than lets say 5000 in 2 seconds you have a brittle test as it is then contextual to the hardware, not just the implementation. Although that being said these sort of automated tests are only really any use if you are running your tests as some sort of build pipeline i.e: Checkout - Run Unit Tests - Run Integration Tests - Run Performance Tests - Package So then you can easily compare the stats from one build to another on the CI server as a report of some sort, and again this may not mean much to anyone if you are not used to Continuous Integration. The main crux of this question is to see how people manage this between builds and how they find it best to report upon. As I said it can be subjective but as knowledge will be gained from the answers it seems a worthwhile question.

Do NOT Change "Copy Local” project references to false, unless understand subsequences.

- by Michael Freidgeim

To optimize performance of visual studio build I've found multiple recommendations to change CopyLocal property for dependent dlls to false,e.g. From http://stackoverflow.com/questions/690033/best-practices-for-large-solutions-in-visual-studio-2008 CopyLocal? For sure turn this offhttp://stackoverflow.com/questions/280751/what-is-the-best-practice-for-copy-local-and-with-project-referencesAlways set the Copy Local property to false and enforce this via a custom msbuild stephttp://codebetter.com/patricksmacchia/2007/06/20/benefit-from-the-c-and-vb-net-compilers-perf/BenefitBenefitMy advice is to always set ‘Copy Local’ to falseSome time ago we've tried to change the setting to false, and found that it causes problem for deployment of top-level projects.Recently I've followed the suggestion and changed the settings for middle-level projects. It didn't cause immediate issues, but I was warned by Readify Consultant Colin Savage about possible errors during deploymentsI haven't undone the changes immediately and we found a few issues during testing.There are many scenarios, when you need to have Copy Local’ left to True.The concerns are highlighted in some stack overflow answers, but they have small number of votes.Top-level projects: set copy local = true.First of all, it doesn't work correctly for top-level projects, i.e. executables or web sites.As pointed in the answer http://stackoverflow.com/a/6529461/52277for all the references in the one at the top set copy local = true.Alternatively you have to change output directory as it's described in http://www.simple-talk.com/dotnet/.net-framework/partitioning-your-code-base-through-.net-assemblies-and-visual-studio-projects/If you set ‘ Copy Local = false’, VS will, unless you tell it otherwise, place each assembly alone in its own .\bin\Debugdirectory. Because of this, you will need to configure VS to place assemblies together in the same directory. To do so, for each VS project, go to VS > Project Properties > Build tab > Output path, and set the Ouput path to ..\bin\Debugfor debug configuration, and ..\bin\Release for release configuration.Second-level dependencies: set copy local = true.Another example when copylocal =false fails on run-time, is when top level assembly doesn't directly referenced one of indirect dependencies.E..g. Top-level assembly A has reference to assembly B with copylocal =true, but assembly B has reference to assembly C with copylocal =false. Most likely assembly C will be missing on runtime and will cause errors E.g. http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1Copy local is important for deployment scenarios and tools. As a general rule you should use CopyLocal=True and http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1 Unfortunately there are some quirks and CopyLocal won't necessary work as expected for assembly references in secondary assemblies structured as shown below.MainApp.exe MyLibrary.dll ThirdPartyLibrary.dll (if in the GAC CopyLocal won't copy to MainApp bin folder)This makes xcopy deployments difficult . .Reflection called DLLs dependencies: set copy local = true.E.g user can see error "ISystem.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."The fix for the issue is recommended in http://stackoverflow.com/a/6200173/52277"I solved this issue by setting the Copy Local attribute of my project's references to true."In general, the problems with investigation of deployment issues may overweight the benefits of reduced build time. Setting the Copy Local to false without considering deployment issues is not a good idea.

The New Social Developer Community: a Q&A

- by Mike Stiles

In our last blog, we introduced the opportunities that lie ahead for social developers as social applications reach across every aspect and function of the enterprise. Leading the upcoming JavaOne Social Developer Program October 2 at the San Francisco Hilton is Roland Smart, VP of Social Marketing at Oracle. I got to ask Roland a few of the questions an existing or budding social developer might want to know as social extends beyond interacting with friends and marketing and into the enterprise. Why is it smart for developers to specialize as social developers? What opportunities lie in the immediate future that’s making this a critical, in-demand position? Social has changed the way we interact with brands and with each other across the web. As we acclimate to a new social paradigm we also look to extend its benefits into new areas of our lives. The workplace is a logical next step, and we're starting to see social interactions more and more in this context. But unlocking the value of social interactions requires technical expertise and knowledge of developing social apps that tap into the social graph. Developers focused on integrating social experiences into enterprise applications must be familiar with popular social APIs and must understand how to build enterprise social graphs of their own. These developers are part of an emerging community of social developers and are key to socially enabling the enterprise. Facebook rebranded their Preferred Developer Consultant Group (PDC) and the Preferred Marketing Developers (PMD) to underscore the fact developers are required inside marketing organizations to unlock the full potential of their platform. While this trend is starting on the marketing side with marketing developers, this is just an extension of the social developer concept that will ultimately drive social across the enterprise. What are some of the various ways social will be making its way into every area of enterprise organizations? How will it be utilized and what kinds of applications are going to be needed to facilitate and maximize these changes? Check out Oracle’s vision for the social-enabled enterprise. It’s a high-level overview of how social will impact across the enterprise. For example: HR can leverage social in recruiting and retentionSales can leverage social as a prospecting toolMarketing can use social to gain market insightCustomer support can use social to leverage community support to improve customer satisfaction while reducing service costOperations can leverage social improve systems That’s only the beginning. Once sleeves get rolled up and social developers and innovators get to work, still more social functions will no doubt emerge. What makes Java one of, if not the most viable platform on which to build these new enterprise social applications? Java is certainly one of the best platforms on which to build social experiences because there’s such a large existing community of Java developers. This means you can affordably recruit talent, and it's possible to effectively solicit advice from the community through various means, including our new Social Developer Community. Beyond that, there are already some great proof points Java is the best platform for creating social experiences at scale. Consider LinkedIn and Twitter. Tell us more about the benefits of collaboration and more about what the Oracle Social Developer Community is. What opportunities does that offer up and what are some of the ways developers can actively participate in and benefit from that community? Much has been written about the overall benefits of collaborating with other developers. Those include an opportunity to introduce yourself to the community of social developers, foster a reputation, establish an expertise, contribute to the advancement of the space, get feedback, experiment with the latest concepts, and gain inspiration. In short, collaboration is a tool that must be applied properly within a framework to get the most value out of it. The OSDC is a place where social developers can congregate to discuss the opportunities/challenges of building social integrations into their applications. What “needs” will this community have? We don't know yet. But we wanted to create a forum where we can engage and understand what social developers are thinking about, excited about, struggling with, etc. The OSDL can then step in if we can help remove barriers and add value in a serious and committed way so Oracle can help drive practice development.

F# WPF Form – the basics

- by MarkPearl

I was listening to Dot Net Rocks show #560 about F# and during the podcast Richard Campbell brought up a good point with regards to F# and a GUI. In essence what I understood his point to be was that until one could write an end to end application in F#, it would be a hard sell to developers to take it on. In part I agree with him, while I am beginning to really enjoy learning F#, I can’t but help feel that I would be a lot further into the language if I could do my Windows Forms like I do in C# or VB.NET for the simple reason that in “playing” applications I spend the majority of the time in the UI layer… So I have been keeping my eye out for some examples of creating a WPF form in a F# project and came across Tim’s F# Twitter Stream Sample, which had exactly this…. of course he actually had a bit more than a basic form… but it was enough for me to scrap the insides and glean what I needed. So today I am going to make just the very basic WPF form with all the goodness of a XAML window. Getting Started First thing we need to do is create a new solution with a blank F# application project – I have made mine called FSharpWPF. Once you have the project created you will need to change the project type from a Console Application to a Windows Application. You do this by right clicking on the project file and going to its properties… Once that is done you will need to add the appropriate references. You do this by right clicking on the References in the Solution Explorer and clicking “Add Reference'”. You should add the appropriate .Net references below for WPF & XAMl to work. Once these references are added you then need to add your XAML file to the project. You can do this by adding a new item to the project of type xml and simply changing the file extension from xml to xaml. Once the xaml file has been added to the project you will need to add valid window XAML. Example of a very basic xaml file is shown below… <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="F# WPF WPF Form" Height="350" Width="525"> <Grid> </Grid> </Window> Once your xaml file is done… you need to set the build action of the xaml file from “None” to “Resource” as depicted in the picture below. If you do not set this you will get an IOException error when running the completed project with a message along the lines of “Cannot locate resource ‘window.xaml’ You then need to tie everything up by putting the correct F# code in the Program.fs to load the xaml window. In the Program.fs put the following code… module Program open System open System.Collections.ObjectModel open System.IO open System.Windows open System.Windows.Controls open System.Windows.Markup [<STAThread>] [<EntryPoint>] let main(_) = let w = Application.LoadComponent(new System.Uri("/FSharpWPF;component/Window.xaml", System.UriKind.Relative)) :?> Window (new Application()).Run(w) Once all this is done you should be able to build and run your project. What you have done is created a WPF based window inside a FSharp project. It should look something like below… Nothing to exciting, but sufficient to illustrate the very basic WPF form in F#. Hopefully in future posts I will build on this to expose button events etc.

To sample or not to sample...

- by [email protected]

Ideally, we would know the exact answer to every question. How many people support presidential candidate A vs. B? How many people suffer from H1N1 in a given state? Does this batch of manufactured widgets have any defective parts? Knowing exact answers is expensive in terms of time and money and, in most cases, is impractical if not impossible. Consider asking every person in a region for their candidate preference, testing every person with flu symptoms for H1N1 (assuming every person reported when they had flu symptoms), or destructively testing widgets to determine if they are "good" (leaving no product to sell). Knowing exact answers, fortunately, isn't necessary or even useful in many situations. Understanding the direction of a trend or statistically significant results may be sufficient to answer the underlying question: who is likely to win the election, have we likely reached a critical threshold for flu, or is this batch of widgets good enough to ship? Statistics help us to answer these questions with a certain degree of confidence. This focuses on how we collect data. In data mining, we focus on the use of data, that is data that has already been collected. In some cases, we may have all the data (all purchases made by all customers), in others the data may have been collected using sampling (voters, their demographics and candidate choice). Building data mining models on all of your data can be expensive in terms of time and hardware resources. Consider a company with 40 million customers. Do we need to mine all 40 million customers to get useful data mining models? The quality of models built on all data may be no better than models built on a relatively small sample. Determining how much is a reasonable amount of data involves experimentation. When starting the model building process on large datasets, it is often more efficient to begin with a small sample, perhaps 1000 - 10,000 cases (records) depending on the algorithm, source data, and hardware. This allows you to see quickly what issues might arise with choice of algorithm, algorithm settings, data quality, and need for further data preparation. Instead of waiting for a model on a large dataset to build only to find that the results don't meet expectations, once you are satisfied with the results on the initial sample, you can take a larger sample to see if model quality improves, and to get a sense of how the algorithm scales to the particular dataset. If model accuracy or quality continues to improve, consider increasing the sample size. Sampling in data mining is also used to produce a held-aside or test dataset for assessing classification and regression model accuracy. Here, we reserve some of the build data (data that includes known target values) to be used for an honest estimate of model error using data the model has not seen before. This sampling transformation is often called a split because the build data is split into two randomly selected sets, often with 60% of the records being used for model building and 40% for testing. Sampling must be performed with care, as it can adversely affect model quality and usability. Even a truly random sample doesn't guarantee that all values are represented in a given attribute. This is particularly troublesome when the attribute with omitted values is the target. A predictive model that has not seen any examples for a particular target value can never predict that target value! For other attributes, values may consist of a single value (a constant attribute) or all unique values (an identifier attribute), each of which may be excluded during mining. Values from categorical predictor attributes that didn't appear in the training data are not used when testing or scoring datasets. In subsequent posts, we'll talk about three sampling techniques using Oracle Database: simple random sampling without replacement, stratified sampling, and simple random sampling with replacement.

Announcing the ASP.NET and Web Tools 2012.2 Release Candidate

- by ScottGu

This week the ASP.NET and Visual Web Developer teams delivered the Release Candidate of the ASP.NET and Web Tools 2012.2 update (formerly ASP.NET Fall 2012 Update BUILD Prerelease). This update extends the existing ASP.NET runtime and adds new web tooling to Visual Studio 2012. Whether you use Web Forms, MVC, Web API, or any other ASP.NET technology, there is something cool in this update for you. You can download and install the RC today: http://www.asp.net/vnext. Great ASP.NET Enhancements This update adds new ASP.NET templates and features, including: New ASP.NET MVC templates. Creating Facebook applications just became easier using the new Facebook Application template. In just a few easy steps you can create a Facebook application that gets data from the logged in user as well as integrates with their friends. A new Single Page Application template allows developers to build interactive client-side web apps using Knockout, jQuery, and ASP.NET Web API. Real-time communication support with ASP.NET SignalR. This enables you to easily take advantage of the new WebSocket support in .NET 4.5, while also automatically degrading to long-polling and other protocols for older clients. If you haven’t tried SignalR yet you should – it is awesome. New ASP.NET Web API functionality, including support for OData, integrated tracing, and automatically generating help page documentation for your API. New ASP.NET Friendly URL functionality. This new feature makes it very easy for Web Forms developers to generate cleaner looking URLs (without the .aspx extension). The Friendly URLs feature also makes it easier for developers to add mobile support to their applications with support for mobile .ASPX pages and supporting switching between desktop and mobile views. It can be used with existing ASP.NET v4.0 applications. Visual Studio 2012 Web publishing enhancements. Web site projects now have the same publish experience as web application projects (including to Windows Azure Web Sites), and you can selectively publish files, see the differences between local and remote files, and update local to remote files or vice versa. Visual Studio 2012 Page Inspector enhancements. JavaScript selection mapping is now supported, and you can CSS updates in real-time. Visual Studio 2012 editor support for Knockout IntelliSense and pasting JSON as a .NET class (which makes it even easier to consume Web APIs from others). Visual Studio 2012 Project Template updates, including the latest versions of jQuery, jQuery UI, jQuery Validation, Modernirz, Knockout and more… How it is delivered You can download and install an integrated setup that contains the above enhancements today from http://www.asp.net/vnext. The new runtime functionality is delivered to ASP.NET via additional NuGet packages. This means that installing this update does not make any changes to the existing ASP.NET binaries, and thus does not cause any compatibility issues with existing projects. New projects will contain the new functionality and existing projects can be updated with the new NuGet packages. Summary Web development is changing, and ASP.NET is rapidly delivering new capabilities to developers that help them take full advantage of new capabilities. The ASP.NET and Web Tools 2012.2 update installs in minutes without altering the current ASP.NET run time components. For a complete description see the Release Notes. Next week I plan to publish a tutorial showing how to build a cool Facebook application using the new Facebook template. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

Unreal Tournament 3 vs UDK: What Should I Choose?

- by Matt Christian

Many people in the mod community were very excited to see the release of the Unreal Developer Kit (UDK) a few months ago. Along with generating excitement into a very dedicated community, it also introduced many new modders into a flourishing area of indie-development. However, since UDK is free, most beginners jump right into UDK, which is OK though you might just benefit more from purchasing a shelf-copy of Unreal Tournament 3. UDK UDK is a free full version of UnrealEd (the editor environment used to create games like Gears of War 1/2, Bioshock 1/2, and of course Unreal Tournament 3). The editor gives you all the features of the editor from the shelf-copy of the game plus some refinements in many of the tools. (One of the first things you'll find about UnrealEd is that it's a collection of tools grouped into the same editor so it really isn't a single 'tool') Interestingly enough, Epic is allowing you to sell any game made in UDK with a few catches. First off, you must purchase a liscense for your game (which, I THINK is aproximately $99 starting). Secondly, you must pay 25% of all profits for the first $5,000 of your game revenue to them (about $1250). Finally, you cannot use any of the 'media' provided in UDK for your game. UDK provides sample meshes, textures, materials, sounds, and other sample pieces of media pulled (mostly) from Unreal Tournament 3. The final point here will really determine whether you should use UDK. There is a very small amount of media provided in UDK for someone to go in and begin creating levels without first developing your own meshes, textures, and other media. Sure, you can slap together a few unique levels, though you will end up finding yourself restriced to the same items over and over and over. This is absolutely how professional game development is; you are 'given' (typically liscensed or built in-house) an engine/editor and you begin creating all the content for the game and placing it. UDK is aimed toward those who really want to build their game content from scratch with a currently existing engine. It is not suited for someone who would like to simply build levels and quick mods without learning external 3D programs and image editing software. Unreal Tournament 3 Unless you have a serious grudge against FPS's, Epic, or your computer sucks, there really is no reason not to own this game for PC. You can pick it up on Steam or Amazon for around $20 brand new. Not only are you provided with a full single-player and multiplayer game, but you are given the entire UnrealEd 3.0 including all of the content used to build UT3. If you want to start building levels and mods quickly for UT3, you should absolutely pick up a shelf-copy. However, as off-the-shelf UT3 is a few years old now, the tools have not been updated for quite a while. Compared to UDK, the menus are more difficult to navigate through and take more time getting used to. Since UDK is updated almost every month, there are new inclusions to the editor that may not be in UT3 (including the future addition of 3D!). I haven't worked enough with shelf UT3 to see if there are more features in UDK or if they both feature the same stuff in different forms, however you should remember that the Unreal Engine 3.0 has undergone numerous upgrades between it's launch and Gears of War 2 (in fact, Epic had a conference to show off what changed just between the Gears of Wars games). Since UT3 has much more core content, someone who wants to focus on level editing or modding the core UT3 game may find their needs better suited with an off-the-shelf copy of UT3. If that level designer has a team that is generating custom assets, they may be better off with UDK. The choice is now yours...

MIXing it Up a Bit

- by andrewbrust

Another March, another MIX. For the fifth year running now, Microsoft has chosen to put on a conference aimed less at software development, per se, and more at the products, experiences and designs that software development can generate. In all four prior MIX events, the focus of the show, its keynotes and breakout sessions has been on Web products. On day 1 of MIX 2010 that focus shifted to Windows Phone 7 Series (WP7). What little we had seen of WP7 had been shown to us in a keynote presentation, given by Microsoft’s Joe Belfiore, at the Mobile World Congress in Barcelona, Spain last month. And today, Mr. Belfiore reprised his showmanship for the MIX 2010 audience. Joe showed us the ins and outs of WP7 and, in a breakout session, even gave us a sneak peek of Office (specifically, Excel) on WP7. We didn’t get to see that one month ago in Barcelona, nor did get to see email messages opened for reading, which we saw today. But beyond a tour of the phone itself, impressive though that is, we got to see apps running on it. Those apps included Associated Press news, Seesmic (a major Twitter client) and Foursquare (a social media darling). All three ran, ran well, and looked markedly different and better from their corresponding versions on iPhone and Android. And the games we saw looked even better. To me though, the best demos involved the creation of WP7 apps, using Silverlight in Visual Studio and Expression Blend. These demos were so effective because they showed important apps being built in very few steps, and by Microsoft executives to boot. Scott Guthrie showed us how to build a Twitter API app in Visual Strudio. Jon Harris showed us how to build a photo management and viewer application in Expression Blend, using virtually no code. Demos of apps built from scratch to F5 without the benefit of a teacher, could be challenging. But they went off fine, without a hitch and without a ton of opaque, generated code. Everything written, be it C# or XAML, was easily understood, and the results were impressive. That means lots of developers can do this, and I think it means a lot will. What I’ve seen, thus far, of iPhone and Android development looks very tedious by comparison. Development for those platforms involve a collection of tools that integrate only to a point. Dev work for WP7 involves use of Visual Studio, Silverlight and the same debugging experience .NET developers already know. This was very exciting for me. All the demos harkened back to days of building apps for with Visual Basic…design the front-end, put in code-behind and then hit F5. And that makes sense, because the phone platform, and the PC of the early 90s are both, essentially, client OS machines. The Web was minimal and the “device” was everything. Same is true of this phone. It’s a client app contraption that fits in your pocket. And if the platforms are comparable, hopefully so too will be the draw of ease-of-development. WP7 has the potential to make mobile developers want to switch over, and to convince enterprise developers to get into the phone scene. Will this propel the new phone platform to new heights, and restore Microsoft’s competiveness in the mobile arena? I hope so. I think so. And if Microsoft uses developers to build themselves a victory, that would be beneficial and would show that Microsoft has learned from its failures, as well as its successes. Today I saw a few beautiful apps. Tomorrow I hope I see a slew of others; maybe not as polished, but plentiful, attractive and stable. That would be a victory for Microsoft, and for developers. And it would show everyone else that developers are the kingmakers. They need cheap, efficient dev tools and lots of respect. Microsoft has always been the company to provide that. Hopefully, with WP7, they will return to that persona and see how very timeless it is.

SQL SERVER – Learn SQL Server 2014 Online in a Day – My Latest Pluralsight Course

- by Pinal Dave

Click here watch SQL Server 2014 Administration New Features. SQL Server 2014 was released earlier this year and it has been extremely popular in Microsoft world. Here is the announcement for everyone, who have been asking me to build a tutorial around SQL Server 2014. I have authored latest Pluralsight courses on the subject of SQL Server 2014. This course is 4 hours and 17 minutes long, but the best part is that this course contains all the latest features of SQL Server 2014. I have build this course with the assumption that DBA is familiar with earlier versions of SQL Server and wants to explore and learn new features of SQL Server 2014. The Challenge I Faced The biggest challenge I faced was how to come up with the outline for the course. The reason is that there are so many different features introduced in SQL Server 2014 that is will be difficult to cover each of the features in a single course. I wanted to cover the topics which are the most relevant and useful to developers, but in addition I also wanted to cover the topics which may be useful to develop if they know that they exists in the product. I finally decided to depend on blog readers and few of the SQL Experts. I reached out to selected 20 people via email and gave them a list of the topics which I should be covering in this course. They all work in different organizations and have a good understanding about the need of the DBA and Developers. Based on their feedback, I was able to come up with a very good outline which is currently very popular with Pluralsight library. Lots of people have asked me how was I able to come up with a course content outline so accurately. The credit for the same goes to the developers and DBA, who have voted in the topics and have helped me to build a very solid outline for the course. Outline of the Course Here is a quick outline for the course: Introduction Backup Enhancements Security Enhancements Columnstore Enhancements Online Data Operations Enhancements Enhancements with Microsoft Azure SSD Buffer Pool Extensions Resource Governor IO Miscellaneous Features Online Index Rebuilding Live Plans for Long Running Queries Transaction Durability Cardinality Estimation In Memory OLTP Optimization Well, I had a great fun working on the topics which I have mentioned in the outline. I am very confident that once you start with the course, you will indeed understand how each of the topics builds and presented. I have made sure that each of the topic has a vivid and clear story to begin with. I first explain the story and right after that I explain the concept. Who Should Attend This Course Everyone who has basic knowledge of SQL Server and wants to update themselves with SQL Server 2014. They should attend this course. One thing I have made sure that this course is easy to understand and I have decided complex subject into multiple parts. This way the learning is progressive and anyone with a poor knowledge of the subject can have enough time to understand the presented concept. Screenshot of the Course Here are few of the screenshot of the courses. How to Watch Video Course This course is available at Pluralsight, and you will need a valid login to Pluralsight. If you do not have Pluralsight login, you can quickly sign up for the FREE Trial. Click here watch SQL Server 2014 Administration New Features.

Building ATLAS (and later Octave w/ ATLAS)

- by David Parks

I'm trying to set up ATLAS (so I can later compile octave with ATLAS support). If I'm correct, I still need to build this manually due to the environment specific optimizations. I do see a package for ATLAS, but it looks like it's using the cross platform generic build options (e.g. "it'll be slow"). So, running the configure script as described in the docs seems to go poorly. As a java developer I never do well at making heads or tails of errors in these build processes. Am I missing dependencies (if so is there any documentation on what I need)? allusers@vbubuntu:~/Downloads/atlas3.10.1/build_vbubuntu$ ../configure -b 64 -D c -DPentiumCPS=3000 --with-netlib-lapack-tarfile=/home/allusers/Downloads/lapack-3.5.0.tgz make: `xconfig' is up to date. ./xconfig -d s /home/allusers/Downloads/atlas3.10.1/build_vbubuntu/../ -d b /home/allusers/Downloads/atlas3.10.1/build_vbubuntu -b 64 -D c -DPentiumCPS=3000 -Si lapackref 1 OS configured as Linux (1) Assembly configured as GAS_x8664 (2) Vector ISA Extension configured as SSE3 (6,448) ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Architecture configured as Corei1 (25) ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Clock rate configured as 2350Mhz ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Maximum number of threads configured as 4 Parallel make command configured as '$(MAKE) -j 4' ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Cannot detect CPU throttling. rm -f config1.out make atlas_run atldir=/home/allusers/Downloads/atlas3.10.1/build_vbubuntu exe=xprobe_comp redir=config1.out \ args="-v 0 -o atlconf.txt -O 1 -A 25 -Si nof77 0 -V 448 -b 64 -d b /home/allusers/Downloads/atlas3.10.1/build_vbubuntu" make[1]: Entering directory `/home/allusers/Downloads/atlas3.10.1/build_vbubuntu' cd /home/allusers/Downloads/atlas3.10.1/build_vbubuntu ; ./xprobe_comp -v 0 -o atlconf.txt -O 1 -A 25 -Si nof77 0 -V 448 -b 64 -d b /home/allusers/Downloads/atlas3.10.1/build_vbubuntu > config1.out make[2]: gfortran: Command not found make[2]: *** [IRunF77Comp] Error 127 make[2]: g77: Command not found make[2]: *** [IRunF77Comp] Error 127 make[2]: f77: Command not found make[2]: *** [IRunF77Comp] Error 127 Unable to find usable compiler for F77; abortingMake sure compilers are in your path, and specify good compilers to configure (see INSTALL.txt or 'configure --help' for details)make[1]: *** [atlas_run] Error 8 make[1]: Leaving directory `/home/allusers/Downloads/atlas3.10.1/build_vbubuntu' make: *** [IRun_comp] Error 2 ERROR 512 IN SYSCMND: 'make IRun_comp args="-v 0 -o atlconf.txt -O 1 -A 25 -Si nof77 0 -V 448 -b 64"' mkdir src bin tune interfaces mkdir: cannot create directory ‘src’: File exists mkdir: cannot create directory ‘bin’: File exists mkdir: cannot create directory ‘tune’: File exists mkdir: cannot create directory ‘interfaces’: File exists make: *** [make_subdirs] Error 1 make -f Make.top startup make[1]: Entering directory `/home/allusers/Downloads/atlas3.10.1/build_vbubuntu' Make.top:1: Make.inc: No such file or directory Make.top:325: warning: overriding commands for target `/AtlasTest' Make.top:76: warning: ignoring old commands for target `/AtlasTest' make[1]: *** No rule to make target `Make.inc'.

Getting Started with NASM

- by MarkPearl

Today I got to play with NASM. This is an assembler and disassembler that can be used to write 16-bit, 32-bit & 64-bit programs. Let me say upfront that the last time I looked at assembly code at any depth was when I was studying Computer Science in Pietermaritzburg – ten years ago – and we never ever got to touch any real assembly code so a lot of what I am looking at today is very new to me. The first thing I did was download NASM compiler. This turned out to be a bit more complicated than I thought. Originally I went to http://www.nasm.us/ and downloaded the nasm-2.09.04.zip file which I thought had all I needed. No luck! It seemed to just have the uncompiled code, and from what I could tell I would need to recompile and build it – possibly in c++? Well, I wasn’t going to waste my time with that, so a bit more searching and I found the Win32 (http://www.nasm.us/pub/nasm/releasebuilds/2.09.04/win32/) folder Nasm.exe which I downloaded. Choosing an IDE So, I have NASM compiler but to compile anything you need to pass a string of special characters in the command prompt. That’s fine if I was going to just do one program once every couple of years, but since I am aiming to do quite a bit more exploration of NASM I began searching for an IDE. There were a few options, even apparently Visual Studio with a bit of tweeking could do the job, but from past experience I wanted to avoid the VS route as it can sometimes get confusing. I eventually settled on TextPad which I had used a few years ago for a similar project and it had been simple enough yet powerful enough to do the job. A bit of searching and I found a syntax file for NASM and everything seemed hunky dory. Configuring TextPad to run the NASM Compiler Next was to get TextPad to run the NASM compiler. TextPad has this external tools option that allows one to configure special commands. To simplify the process I first created a bat file in the NASM directory that allowed me to simply compile asm files. The bat file was called as.bat and had just one line of code… nasm -f bin %1.asm -o %1.com -l %1.lst Once I had created as.bat I just needed to go into TextPad and create a tool. I have made a quick video of that just showing you where the various settings are which is viewable below. The 64Bit Problem So I now have an ‘IDE’ linked to my NASM compiler so everything should be fine right? No! Whenever I tried to compile an asm program it compiles fine, but when I try and run it I get an error – “This version of the file is not compatible with the version Windows you’re running. Check your computer’s system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." Well.. it turns out there are a few complications with having a 64 bit OS! So after searching google and coming to any real solution that I could find other than perhaps attempting to build the code for nasm, I eventually resorted to running a VM with Windows XP on it and putting NASM there… My first hello world program So I attempt my first hello world program as per an example I found… the code was quite simple and is shown below… bits16 org 0x100 jmp main message: db 'Hello World',0ah,0dh,'$' main: mov dx,message mov ah,09 int 21h int 20h Running the build tool from TextPad and everything compiles fine and I now have a console app with helllo world shown. Conclusion It’s very early days with NASM. I have been spoilt with Visual Studio and high order languages so I assume it will be a painful ride getting into the basics of assembly programming but I am hoping that at the end of it, I will at least have a bit more exposure to a language closer to the metal.

Hyper-V for Developers Part 1 Internal Networks

Over the last year, weve been working with Microsoft to build training and demo content for the next version of Office Communications Server code-named Microsoft Communications Server 14. This involved building multi-server demo environments in Hyper-V, getting them running on demo servers which we took to TechEd, PDC, and other training events, and sometimes connecting the demo servers to the show networks at those events. ITPro stuff that should scare the hell out of a developer! It can get ugly when I occasionally have to venture into ITPro land. Lets leave it at that. Having gone through this process about 10 to 15 times in the last year, I finally have it down. This blog series is my attempt to put all that knowledge in one place if anything, so I can find it somewhere when I need it again. Ill start with the most simple scenario and then build on top of it in future blog posts. If youre an ITPro, please resist the urge to laugh at how trivial this is. Internal Hyper-V Networks Lets start simple. An internal network is one that intended only for the virtual machines that are going to be on that network it enables them to communicate with each other. Create an Internal Network On your host machine, fire up the Hyper-V Manager and click the Virtual Network Manager in the Actions panel. Select Internal and leave all the other default values. Give the virtual network a name, and leave all the other default values. After the virtual network is created, open the Network and Sharing Center and click Change Adapter Settings to see the list of network connections. The only thing I recommend that you do is to give this connection a friendly label, e.g. Hyper-V Internal. When you have multiple networks and virtual networks on the host machines, this helps group the networks so you can easily differentiate them from each other. Otherwise, dont touch it, only bad things can happen. Connect the Virtual Machines to the Internal Network Im assuming that you have more than 1 virtual machine already configured in Hyper-V, for example a Domain Controller, and Exchange Server, and a SharePoint Server. What you need to do is basically plug in the network to the virtual machine. In order to do this, the machine needs to have a virtual network adapter. If the VM doesnt have a network adapter, open the VMs Settings and click Add Hardware in the left pane. Choose the virtual network to which to bind the adapter to. If you already have a virtual network adapter on the VM, simply connect it to the virtual network. Assign IP Addresses to the Virtual Machines on the Internal Network Open the Network and Sharing Center on your VM, there should only be 1 network at this time. Open the Properties of the connection, select Internet Protocol Version 4 (TCP/IPv4) and hit Properties. In this environment, Im assigning IP addresses as 192.168.0.xxx. This particular VM has an IP address of 192.168.0.40 with a subnet mask of 255.255.255.0, and a DNS Server of 192.168.0.18. DNS is running on the Domain Controller VM which has an IP address of 192.168.0.18. Repeat this process on every VM in your environment, obviously assigning a unique IP address to each. In an environment with a domain controller, you should now be able to ping the machines from each other. What Next? After completing this process, heres what you still cannot do: Access the internet from any of the VMs Remote desktop to a VM from the host Remote desktop to a VM over the network In the next post, well take a look configuring an External network adapter on the virtual machines. Well then build on top of that so that you can RDP into the VMs from the host machine and over the network.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

Server-Sent Events using GlassFish (TOTD #179)

- by arungupta

Bhakti blogged about Server-Sent Events on GlassFish and I've been planning to try it out for past some days. Finally, I took some time out today to learn about it and build a simplistic example showcasing the touch points. Server-Sent Events is developed as part of HTML5 specification and provides push notifications from a server to a browser client in the form of DOM events. It is defined as a cross-browser JavaScript API called EventSource. The client creates an EventSource by requesting a particular URL and registers an onmessage event listener to receive the event notifications. This can be done as shown var url = 'http://' + document.location.host + '/glassfish-sse/simple';eventSource = new EventSource(url);eventSource.onmessage = function (event) { var theParagraph = document.createElement('p'); theParagraph.innerHTML = event.data.toString(); document.body.appendChild(theParagraph);} This code subscribes to a URL, receives the data in the event listener, adds it to a HTML paragraph element, and displays it in the document. This is where you'll parse JSON and other processing to display if some other data format is received from the URL. The URL to which the EventSource is subscribed to is updated on the server side and there are multipe ways to do that. GlassFish 4.0 provide support for Server-Sent Events and it can be achieved registering a handler as shown below: @ServerSentEvent("/simple")public class MySimpleHandler extends ServerSentEventHandler { public void sendMessage(String data) { try { connection.sendMessage(data); } catch (IOException ex) { . . . } }} And then events can be sent to this handler using a singleton session bean as shown: @Startup@Statelesspublic class SimpleEvent { @Inject @ServerSentEventContext("/simple") ServerSentEventHandlerContext<MySimpleHandler> simpleHandlers; @Schedule(hour="*", minute="*", second="*/10") public void sendDate() { for(MySimpleHandler handler : simpleHandlers.getHandlers()) { handler.sendMessage(new Date().toString()); } }} This stateless session bean injects ServerSentEventHandlers listening on "/simple" path. Note, there may be multiple handlers listening on this path. The sendDate method triggers every 10 seconds and send the current timestamp to all the handlers. The client side browser simply displays the string. The HTTP request headers look like: Accept: text/event-streamAccept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3Accept-Encoding: gzip,deflate,sdchAccept-Language: en-US,en;q=0.8Cache-Control: no-cacheConnection: keep-aliveCookie: JSESSIONID=97ff28773ea6a085e11131acf47bHost: localhost:8080Referer: http://localhost:8080/glassfish-sse/faces/index2.xhtmlUser-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.54 Safari/536.5 And the response headers as: Content-Type: text/event-streamDate: Thu, 14 Jun 2012 21:16:10 GMTServer: GlassFish Server Open Source Edition 4.0Transfer-Encoding: chunkedX-Powered-By: Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 4.0 Java/Apple Inc./1.6) Notice, the MIME type of the messages from server to the client is text/event-stream and that is defined by the specification. The code in Bhakti's blog can be further simplified by using the recently-introduced Twitter API for Java as shown below: @Schedule(hour="*", minute="*", second="*/10") public void sendTweets() { for(MyTwitterHandler handler : twitterHandler.getHandlers()) { String result = twitter.search("glassfish", String.class); handler.sendMessage(result); }} The complete source explained in this blog can be downloaded here and tried on GlassFish 4.0 build 34. The latest promoted build can be downloaded from here and the complete source code for the API and implementation is here. I tried this sample on Chrome Version 19.0.1084.54 on Mac OS X 10.7.3.

Patterns for a tree of persistent data with multiple storage options?

- by Robin Winslow

I have a real-world problem which I'll try to abstract into an illustrative example. So imagine I have data objects in a tree, where parent objects can access children, and children can access parents: // Interfaces interface IParent<TChild> { List<TChild> Children; } interface IChild<TParent> { TParent Parent; } // Classes class Top : IParent<Middle> {} class Middle : IParent<Bottom>, IChild<Top> {} class Bottom : IChild<Middle> {} // Usage var top = new Top(); var middles = top.Children; // List<Middle> foreach (var middle in middles) { var bottoms = middle.Children; // List<Bottom> foreach (var bottom in bottoms) { var middle = bottom.Parent; // Access the parent var top = middle.Parent; // Access the grandparent } } All three data objects have properties that are persisted in two data stores (e.g. a database and a web service), and they need to reflect and synchronise with the stores. Some objects only request from the web service, some only write to it. Data Mapper My favourite pattern for data access is Data Mapper, because it completely separates the data objects themselves from the communication with the data store: class TopMapper { public Top FetchById(int id) { var top = new Top(DataStore.TopDataById(id)); top.Children = MiddleMapper.FetchForTop(Top); return Top; } } class MiddleMapper { public Middle FetchById(int id) { var middle = new Middle(DataStore.MiddleDataById(id)); middle.Parent = TopMapper.FetchForMiddle(middle); middle.Children = BottomMapper.FetchForMiddle(bottom); return middle; } } This way I can have one mapper per data store, and build the object from the mapper I want, and then save it back using the mapper I want. There is a circular reference here, but I guess that's not a problem because most languages can just store memory references to the objects, so there won't actually be infinite data. The problem with this is that every time I want to construct a new Top, Middle or Bottom, it needs to build the entire object tree within that object's Parent or Children property, with all the data store requests and memory usage that that entails. And in real life my tree is much bigger than the one represented here, so that's a problem. Requests in the object In this the objects request their Parents and Children themselves: class Middle { private List<Bottom> _children = null; // cache public List<Bottom> Children { get { _children = _children ?? BottomMapper.FetchForMiddle(this); return _children; } set { BottomMapper.UpdateForMiddle(this, value); _children = value; } } } I think this is an example of the repository pattern. Is that correct? This solution seems neat - the data only gets requested from the data store when you need it, and thereafter it's stored in the object if you want to request it again, avoiding a further request. However, I have two different data sources. There's a database, but there's also a web service, and I need to be able to create an object from the web service and save it back to the database and then request it again from the database and update the web service. This also makes me uneasy because the data objects themselves are no longer ignorant of the data source. We've introduced a new dependency, not to mention a circular dependency, making it harder to test. And the objects now mask their communication with the database. Other solutions Are there any other solutions which could take care of the multiple stores problem but also mean that I don't need to build / request all the data every time?

Running MSBuild fails to read SDKToolsPath

- by Scott Mayfield

Howdy, I'm having a bit of an issue runnning a NAnt script that used to properly build my .Net 2.0 based website, when compiling with VS2008 and it's associated tools. I've recently upgraded all the project/solution files to VS2010, and now my build fails with the following error: [exec] C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets(2249,9): error MSB3086: Task could not find "sgen.exe" using the S dkToolsPath "" or the registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.0A". Make sure the SdkToolsPath is set and the tool exists in the correct processor specific location under the SdkToolsPath and that the Microsoft Windows SDK is installed Now, I DO have prior versions (.Net 3.5) of the Windows SDK installed on the build server, and the full .Net 4.0 framework is installed, but I've not run across a .Net 4.0 specific version of the Windows SDK. After a bit of experimentation and research, I finally just setup a new environmental variable "SDKToolsPath" and pointed it to the copy of sgen.exe in my windows 6.0 sdk folder. This generated the same error, but it got me to notice that even though the SDKToolsPath environmental variable IS set (confirmed that I can "echo" it at the command line and it has the expected value), the error message seems to indicated that it's not being read (note the empty quotes). Most of the information I've found is .Net 3.5 (or earlier) specific. Not much 4.0 related out there yet. Searching for error code MSB3086 generated nothing useful either. Any idea what this might be? Scott

WPF ToggleButton changing image depending on state

- by mack369

I would like to use ToggleButton in following way: There are 5 different images and each of them should be displayed depending on current state: button disabled button enabled, unchecked button enabled, unchecked, pointed by mouse cursor button enabled, checked button enabled, checked, pointed by mouse cursor I've found a simple example with two images on http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/28c36bd2-2ef7-4232-9976-2a0967140e32 , but how to change the image depending on "checked" property? The second question: how can I avoid creating different styles for each button in my application? I'm using about 20 different buttons and each of them has different set of icons. So far I'm using only one icon, below my code. Is it possible to have common code (style and template) and to define the source of images in section where I want to create button (like in section 3 of my code)? <ControlTemplate x:Key="ToggleButtonTemplate" TargetType="{x:Type ToggleButton}"> <Grid> <Border x:Name="ContentBorder" CornerRadius="4" BorderBrush="Transparent" BorderThickness="1" Background="{DynamicResource ButtonOff}"> <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True"/> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsChecked" Value="true"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonOn}"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter TargetName="ContentBorder" Property="Background" Value="{DynamicResource ButtonDisabled}"/> <Setter Property="Foreground" Value="{DynamicResource BorderDisabled}"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> <Style x:Key="ToggleButtonStyle" TargetType="{x:Type ToggleButton}"> <Setter Property="Width" Value="64" /> <Setter Property="Height" Value="64" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Template" Value="{DynamicResource ToggleButtonTemplate}" /> </Style> <ToggleButton IsChecked="{Binding Path=IsLectorModeEnabled}" Command="{Binding CmdLector}" Style="{DynamicResource ToggleButtonStyle}"> <Image Source="{DynamicResource LectorImage}" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="None" /> </ToggleButton>

android sdk main.out.xml parsing error?

I just started a new Android project, "WeekendStudy" to continue learning Android development and I got stumped compiling the default 'hello weekendstudy' compile / run.

Using Visual Studio 2008 to Assemble, Link, Debug, and Execute MASM 6.11 Assembly Code

- by Kreychek

I would like to use Visual Studio 2008 to the greatest extent possible while effectively compiling/linking/building/etc code as if all these build processes were being done by the tools provided with MASM 6.11. The exact version of MASM does not matter, so long as it's within the 6.x range, as that is what my college is using to teach 16-bit assembly. I have done some research on the subject and have come to the conclusion that there are several options: Reconfigure VS to call the MASM 6.11 executables with the same flags, etc as MASM 6.11 would natively do. Create intermediary batch file(s) to be called by VS to then invoke the proper commands for MASM's linker, etc. Reconfigure VS's built-in build tools/rules (assembler, linker, etc) to provide an environment identical to the one used by MASM 6.11. Option (2) was brought up when I realized that the options available in VS's "External Tools" interface may be insufficient to correctly invoke MASM's build tools, thus a batch file to interpret VS's strict method of passing arguments might be helpful, as a lot of my learning about how to get this working involved my manually calling ML.exe, LINK.exe, etc from the command prompt. Below are several links that may prove useful in answering my question. Please keep in mind that I have read them all and none are the actual solution. I can only hope my specifying MASM 6.11 doesn't prevent anyone from contributing a perhaps more generalized answer. Similar method used to Option (2), but users on the thread are not contactable: http://www.codeguru.com/forum/archive/index.php/t-284051.html (also, I have my doubts about the necessity of an intermediary batch file) Out of date explanation to my question: http://www.cs.fiu.edu/~downeyt/cop3402/masmaul.html Probably the closest thing I've come to a definitive solution, but refers to a suite of tools from something besides MASM, also uses a batch file: http://www.kipirvine.com/asm/gettingStarted/index.htm#16-bit I apologize if my terminology for the tools used in each step of the code - exe process is off, but since I'm trying to reproduce the entirety of steps in between completion of writing the code and generating an executable, I don't think it matters much.

Problems with builds on TFS 2010 and resolving dependencies

- by Jimmy Engtröm

Hi I have a project that works great on my machine (and production servers). It's a VS2010 project running C#3.5. When letting my build server build the solution it can't resolve a couple of my third party dll's. Error message: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets(1360,9): warning MSB3268: The primary reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v3.5". To resolve this problem, either remove the reference "Third.Party.Assembly, Version=50.11.2.0, Culture=neutral, PublicKeyToken=0561a7c6dbd6f0ea, processorArchitecture=MSIL" or retarget your application to a framework version which contains "Microsoft.VisualBasic.Compatibility, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". [d:\Builds\3\mySolution.sln] Everything compiles and runs great on my machine, but the build server seem to struggle. I think the Third.Party.Assembly is written in VB.net. Since the assembly is third party I can't remove the reference to "Microsoft.VisualBasic.Compatibility" and since I don't get any warnings on my computer could it really be that I'm running v3.5? Any suggestions? /Jimmy

Entity Framework - Condition on one to many join (Lambda)

- by nirpi

Hi, I have 2 entities: Customer & Account, where a customer can have multiple accounts. On the account, I have a "PlatformTypeId" field, which I need to condition on (multiple values), among other criterions. I'm using Lambda expressions, to build the query. Here's a snippet: var customerQuery = (from c in context.CustomerSet.Include("Accounts") select c); if (criterions.UserTypes != null && criterions.UserTypes.Count() > 0) { List<short> searchCriterionsUserTypes = criterions.UserTypes.Select(i => (short)i).ToList(); customerQuery = customerQuery.Where(CommonDataObjects.LinqTools.BuildContainsExpression<Customer, short>(c => c.UserTypeId, searchCriterionsUserTypes)); } // Other criterions, including the problematic platforms condition (below) var customers = customerQuery.ToList(); I can't figure out how to build the accounts' platforms condition: if (criterions.Platforms != null && criterions.Platforms.Count() > 0) { List<short> searchCriterionsPlatforms = criterions.Platforms.Select(i => (short)i).ToList(); customerQuery = customerQuery.Where(c => c.Accounts.Where(LinqTools.BuildContainsExpression<Account, short>(a => a.PlatformTypeId, searchCriterionsPlatforms))); } (The BuildContainsExpression is a method we use to build the expression for the multi-select) I'm getting a compilation error: The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. Any idea how to fix this? Thanks, Nir.

getting a job in game industry as a developer, just knowing a game engine

- by numerical25

I recently enrolled at a community college for game developement. But I am skeptical about the circulum. I have no experience in the gaming industry so I wouldnt be able to tell rather its a good investment or not. So I am asking you. I dont want to get too much into detail of all the classes I am taking so I will try to be brief. By the time I graduate, I should have a understanding of how a game engine works. I will be working with the unreal engine to develop a Multiplayer game from scratch. So in the process of my final project, I will learn how to work within the unreal engine, Learn python and learn how to use it's API to connect to a remote server and build game mechanics. Overall I will also recieve a associates degree in game development. I learn c++ but not c. The director said he was trying to implement c in the program as well. What I notice is I will not learn how to build a 3d game engine from scratch. They do not teach any AI. I will not learn how to work with the graphics card using a graphic's api such as DirectX or OpenGL. I know building a game engine from scratch is a little complex, but at the same time the track is requireing me to take some advances math courses such a calculus and geotomtry 1 and 2. I also got to take a physic class. I just think thats a little much for just learning how to use the unreal engine but not actually build one or try to learn the anatomy of a game engine. Is this good enough to possibly land my a job in the insdustry. If I left anything out or was not detail, please feel free to ask more questions. Thanks Guys!!
