• Chuck Norris Be Thy Name

  - by Robz / Fervent Coder

  Chuck Norris doesn’t program with a keyboard. He stares the computer down until it does what he wants. All things need a name. We’ve tossed around a bunch of names for the framework of tools we’ve been working on, but one we kept coming back to was Chuck Norris. Why did we choose Chuck Norris? Well Chuck Norris sort of chose us. Everything we talked about, the name kept drawing us closer to it. We couldn’t escape Chuck Norris, no matter how hard we tried. So we gave in. Chuck Norris can divide by zero. What is the Chuck Norris Framework? @drusellers and I have been working on a variety of tools: WarmuP - http://github.com/chucknorris/warmup (Template your entire project/solution and create projects ready to code - From Zero to a Solution with everything in seconds. Your templates, your choices.) UppercuT - http://projectuppercut.org (Build with Conventions - Professional Builds in Moments, Not Days!) | Code also at http://github.com/chucknorris/uppercut DropkicK - http://github.com/chucknorris/dropkick (Deploy Fluently) RoundhousE - http://projectroundhouse.org (Professional Database Management with Versioning) | Code also at http://github.com/chucknorris/roundhouse SidePOP - http://sidepop.googlecode.com (Does your application need to check email?) HeadlocK - http://github.com/chucknorris/headlock (Hash a directory so you can later know if anything has changed) Others – still in concept or vaporware People ask why we choose such violent names for each tool of our framework? At first it was about whipping your code into shape, but after awhile the naming became, “How can we relate this to Chuck Norris?” People also ask why we uppercase the last letter of each name. Well, that’s more about making you ask questions…but there are a few reasons for it. Project managers never ask Chuck Norris for estimations…ever. The class object inherits from Chuck Norris Chuck Norris doesn’t need garbage collection because he doesn’t call .Dispose(), he calls .DropKick() So what are you waiting for? Join the Google group today, download and play with the tools. And lastly, welcome to Chuck Norris. Or should I say Chuck Norris welcomes you…

• BoundingBox created from mesh to origin, making it bigger

  - by Gunnar Södergren

  I'm working on a level-based survival game and I want to design my scenes in Maya and export them as a single model (with multiple meshes) into XNA. My problem is that when I try to create Bounding Boxes(for Collision purposes) for each of the meshes, the are calculated from origin to the far-end of the current mesh, so to speak. I'm thinking that it might have something to do with the position each mesh brings from Maya and that it's interpreted wrongly... or something. Here's the code for when I create the boxes: private static BoundingBox CreateBoundingBox(Model model, ModelMesh mesh) { Matrix[] boneTransforms = new Matrix[model.Bones.Count]; model.CopyAbsoluteBoneTransformsTo(boneTransforms); BoundingBox result = new BoundingBox(); foreach (ModelMeshPart meshPart in mesh.MeshParts) { BoundingBox? meshPartBoundingBox = GetBoundingBox(meshPart, boneTransforms[mesh.ParentBone.Index]); if (meshPartBoundingBox != null) result = BoundingBox.CreateMerged(result, meshPartBoundingBox.Value); } result = new BoundingBox(result.Min, result.Max); return result; } private static BoundingBox? GetBoundingBox(ModelMeshPart meshPart, Matrix transform) { if (meshPart.VertexBuffer == null) return null; Vector3[] positions = VertexElementExtractor.GetVertexElement(meshPart, VertexElementUsage.Position); if (positions == null) return null; Vector3[] transformedPositions = new Vector3[positions.Length]; Vector3.Transform(positions, ref transform, transformedPositions); for (int i = 0; i < transformedPositions.Length; i++) { Console.WriteLine(" " + transformedPositions[i]); } return BoundingBox.CreateFromPoints(transformedPositions); } public static class VertexElementExtractor { public static Vector3[] GetVertexElement(ModelMeshPart meshPart, VertexElementUsage usage) { VertexDeclaration vd = meshPart.VertexBuffer.VertexDeclaration; VertexElement[] elements = vd.GetVertexElements(); Func<VertexElement, bool> elementPredicate = ve => ve.VertexElementUsage == usage && ve.VertexElementFormat == VertexElementFormat.Vector3; if (!elements.Any(elementPredicate)) return null; VertexElement element = elements.First(elementPredicate); Vector3[] vertexData = new Vector3[meshPart.NumVertices]; meshPart.VertexBuffer.GetData((meshPart.VertexOffset * vd.VertexStride) + element.Offset, vertexData, 0, vertexData.Length, vd.VertexStride); return vertexData; } } Here's a link to the picture of the mesh(The model holds six meshes, but I'm only rendering one and it's bounding box to make it clearer: http://www.gsodergren.se/portfolio/wp-content/uploads/2011/10/Screen-shot-2011-10-24-at-1.16.37-AM.png The mesh that I'm refering to is the Cubelike one. The cylinder is a completely different model and not part of any bounding box calculation. I've double- (and tripple-)-checked that this mesh corresponds to this bounding box. Any thoughts on what I'm doing wrong?

• How Microsoft listens

  - by Stacy Vicknair

  This being my freshman year as an MVP, I had a realization that I perhaps should be embarrassed hasn’t happened sooner. The realization comes much like the iconic M&Ms commercial where the M&Ms run into Santa and exclaim, “He does exist!” My personal realization arguably has a greater implication: Microsoft does listen. This is the most important lesson that I received this year attending the MVP Summit. My hope is that I can convince you that we are empowered to make a difference. Instead of using “Man I hate how this works / doesn’t work!” as cooler conversation, we can use it as true interaction with Microsoft. We as customers to Microsoft need to stop asking the question “Will this work for me?” and instead ask “How can this work for me?” There are three quick resources that the average developer has access to today that they can use to be heard by the product teams, and by no means should you think twice if you have a concern that you’d like a real response on. MVPs MVPs are members of your community who have a deep relationship with Microsoft and will have connections to their associated product group. Don’t think of them as just a resource for answers, but also as your ambassador for getting your experiences heard. You can find your local MVPs by browsing the directory at: https://mvp.support.microsoft.com/communities/mvp.aspx Evangelists Evangelists are employees of Microsoft who work to foster and grow communities in their assigned region. They are first-class citizens of Microsoft and are often deeply involved with the product groups. As a result, they will be more than glad to direct your questions or concerns to those who can answer them most expertly. With that said, evangelists are also very busy people (who do amazing things for the community) and might not be able to get you that conversation as quickly as a local MVP. You can find your local evangelist at the following website: http://msdn.microsoft.com/en-us/bb905078.aspx Microsoft Connect This is one of the resources that I haven’t used enough, but it cannot be understated. Connect is the starting point of the social conversation that happens between Microsoft and the community daily. Connect acts as a portal where you can provide new feedback as well as comment and rate the feedback provided by others. Power is in numbers when it comes to Connect, so the exposure that your feedback can get not only lets you know that you aren’t the only one who wants change, but also lets Microsoft know the same. https://connect.microsoft.com   Technorati Tags: Microsoft,MVP,Feedback,Connect

• SharePoint 2010 Hosting :: Hiding SharePoint 2010 Ribbon From Anonymous Users

  - by mbridge

  The user interface improvements in SharePoint 2010 as a whole are truly amazing. Microsoft has brought this already impressive product leaps and bounds in terms of accessibility, standards, and usability. One thing you might be aware of is the new and quite useful “ribbon” control that appears by default at the top of every SharePoint 2010 master page. Here’s a sneak peek: You’ll see this ribbon not only in the 2010 web interface, but also throughout the entire family of Office products coming out this year. Even SharePoint Designer 2010 makes use of the ribbon in a very flexible and useful way. Hiding The Ribbon In SharePoint 2010, the ribbon is used almost exclusively for content creation and site administration. It doesn’t make much sense to show the ribbon on a public-facing internet site (in fact, it can really retract from your site’s design when it appears), so you’ll probably want to hide the ribbon when users aren’t logged in. Here’s how it works: <SharePoint:SPSecurityTrimmedControl PermissionsString="ManagePermissions" runat="server">     <div id="s4-ribbonrow" class="s4-pr s4-ribbonrowhidetitle">         <!-- Ribbon code appears here... -->     </div> </SharePoint:SPSecurityTrimmedControl> In your master page, find the SharePoint ribbon by looking for the line of code that begins with <div id=”s4-ribbonrow”>. Place the SPSecurityTrimmedControl code around your ribbon to conditionally hide it based on user permissions. In our example, we’ve hidden the ribbon from any user who doesn’t have the ManagePermissions ability, which is going to be almost any user short of a site administrator. Other Permission Levels You can specify different permission levels for the SPSecurityTrimmedControl, allowing you to configure exactly who can see the SharePoint 2010 ribbon. Basically, this control will hide anything inside of it when users don’t have the specified PermissionString. The available options include: 1. List Permissions - ManageLists - CancelCheckout - AddListItems - EditListItems - DeleteListItems - ViewListItems - ApproveItems - OpenItems - ViewVersionsDeleteVersions - CreateAlerts - ViewFormPages 2. Site Permissions - ManagePermissions - ViewUsageData - ManageSubwebs - ManageWeb - AddAndCustomizePages - ApplyThemeAndBorder - ApplyStyleSheets - CreateGroups - BrowseDirectories - CreateSSCSite - ViewPages - EnumeratePermissions - BrowseUserInfo - ManageAlerts - UseRemoteAPIs - UseClientIntegration - Open - EditMyUserInfo 3. Personal Permissions - ManagePersonalViews - AddDelPrivateWebParts - UpdatePersonalWebParts You can use this control to hide anything in your master page or on related page layouts, so be sure to keep it in mind when you’re trying to hide/show things conditionally based on user permission. The One Catch You may notice that the login control (or welcome control) is actually inside the ribbon by default in SharePoint 2010. You’ll probably want to pull this control out of the ribbon and place it elsewhere on your page. Just look for the line of code that looks like this: <wssuc:Welcome id="IdWelcome" runat="server" EnableViewState=”false”/> Move this code out of the ribbon and into another location within your master page. Save your changes, check in and approve all files, and anonymous users will never know your site is built on SharePoint 2010!

• Camera rotation - First Person Camera using GLM

  - by tempvar

  I've just switched from deprecated opengl functions to using shaders and GLM math library and i'm having a few problems setting up my camera rotations (first person camera). I'll show what i've got setup so far. I'm setting up my ViewMatrix using the glm::lookAt function which takes an eye position, target and up vector // arbitrary pos and target values pos = glm::vec3(0.0f, 0.0f, 10.0f); target = glm::vec3(0.0f, 0.0f, 0.0f); up = glm::vec3(0.0f, 1.0f, 0.0f); m_view = glm::lookAt(pos, target, up); i'm using glm::perspective for my projection and the model matrix is just identity m_projection = glm::perspective(m_fov, m_aspectRatio, m_near, m_far); model = glm::mat4(1.0); I send the MVP matrix to my shader to multiply the vertex position glm::mat4 MVP = camera->getProjection() * camera->getView() * model; // in shader gl_Position = MVP * vec4(vertexPos, 1.0); My camera class has standard rotate and translate functions which call glm::rotate and glm::translate respectively void camera::rotate(float amount, glm::vec3 axis) { m_view = glm::rotate(m_view, amount, axis); } void camera::translate(glm::vec3 dir) { m_view = glm::translate(m_view, dir); } and i usually just use the mouse delta position as the amount for rotation Now normally in my previous opengl applications i'd just setup the yaw and pitch angles and have a sin and cos to change the direction vector using (gluLookAt) but i'd like to be able to do this using GLM and matrices. So at the moment i have my camera set 10 units away from the origin facing that direction. I can see my geometry fine, it renders perfectly. When i use my rotation function... camera->rotate(mouseDeltaX, glm::vec3(0, 1, 0)); What i want is for me to look to the right and left (like i would with manipulating the lookAt vector with gluLookAt) but what's happening is It just rotates the model i'm looking at around the origin, like im just doing a full circle around it. Because i've translated my view matrix, shouldn't i need to translate it to the centre, do the rotation then translate back away for it to be rotating around the origin? Also, i've tried using the rotate function around the x axis to get pitch working, but as soon as i rotate the model about 90 degrees, it starts to roll instead of pitch (gimbal lock?). Thanks for your help guys, and if i've not explained it well, basically i'm trying to get a first person camera working with matrix multiplication and rotating my view matrix is just rotating the model around the origin.

• ASP.NET MVC 4: Short syntax for script and style bundling

  - by DigiMortal

  ASP.NET MVC 4 introduces new methods for style and scripts bundling. I found something brilliant there I want to introduce you. In this posting I will show you how easy it is to include whole folder with stylesheets or JavaScripts to your page. I’m using ASP.NET MVC 4 Internet Site template for this example. When we open layout pages located in shared views folder we can see something like this in layout file header: <link href="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Content/css")" rel="stylesheet" type="text/css" />    <link href="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Content/themes/base/css")" rel="stylesheet" type="text/css" />    <script src="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Scripts/js")"></script> Let’s take the last line and modify it so it looks like this: <script src="/Scripts/js"></script> After saving the layout page let’s run browser and see what is coming in over network. As you can see the request to folder ended up with result code 200 which means that request was successful. 327.2KB was received and it is not mark-up size for error page or directory index. Here is the body of response: I scrolled down to point where one script ends and another one starts when I made the screenshot above. All scripts delivered with ASP.NET MVC project templates start with this green note. So now we can be sure that the request to scripts folder ended up with bundled script and not with something else. Conclusion Script and styles bundling uses currently by default long syntax where bundling is done through Bundling class. We can still avoid those long lines and use extremely short syntax for script and styles bundling – we just write usual script or link tag and give folder URL as source. ASP.NET MVC 4 is smart enough to combine styles or scripts when request like this comes in.

• Delegates in c#

  - by Jalpesh P. Vadgama

  I have used delegates in my programming since C# 2.0. But I have seen there are lots of confusion going on with delegates so I have decided to blog about it. In this blog I will explain about delegate basics and use of delegates in C#. What is delegate? We can say a delegate is a type safe function pointer which holds methods reference in object. As per MSDN it's a type that references to a method. So you can assign more than one methods to delegates with same parameter and same return type. Following is syntax for the delegate public delegate int Calculate(int a, int b); Here you can see the we have defined the delegate with two int parameter and integer parameter as return parameter. Now any method that matches this parameter can be assigned to above delegates. To understand the functionality of delegates let’s take a following simple example. using System; namespace Delegates { class Program { public delegate int CalculateNumber(int a, int b); static void Main(string[] args) { int a = 5; int b = 5; CalculateNumber addNumber = new CalculateNumber(AddNumber); Console.WriteLine(addNumber(5, 6)); Console.ReadLine(); } public static int AddNumber(int a, int b) { return a + b; } } } Here in the above code you can see that I have created a object of CalculateNumber delegate and I have assigned the AddNumber static method to it. Where you can see in ‘AddNumber’ static method will just return a sum of two numbers. After that I am calling method with the help of the delegates and printing out put to the console application. Now let’s run the application and following is the output as expected. That’s it. You can see the out put of delegates after adding a number. This delegates can be used in variety of scenarios. Like in web application we can use it to update one controls properties from another control’s action. Same you can also call a delegates whens some UI interaction done like button clicked. Hope you liked it. Stay tuned for more. In next post I am going to explain about multicast delegates. Till then happy programming.

• Odd Profiler Results with EF4

  - by AjarnMark

  I have been doing some testing of using the Microsoft Entity Framework 4 with stored procedures and ran across some really odd results in SQL Server Profiler. The application that is running which uses Entity Framework 4 is a simple Web Application written in C#, and the Entity Data Model is actually contained in a referenced class library of its own.  I’ll write more about my experiences with this later.  For now the question is, why does SQL Profiler think that the stored procedure is running in Master, and not in my application database? While analyzing the effects of using custom helper methods on my EDM classes to call the stored procedure, I decided to run Profiler while I stepped through the code so that I had a clear understanding of exactly when and what calls were made to the SQL Server.  I ran Profiler switching back and forth between the TSQL and TSQL_SP templates.  However, to reduce the amount of results rows I needed to wade through, I set a filter on DatabaseID to be equal to my application’s database.  Each time I ran this, the only thing that I saw was an Audit:Login to the database, but no procedure or T-SQL statements executed, yet I was definitely getting results back to my web page.  I tried other Profiler templates, still filtering on DatabaseID (tangent: I found, at least back in SQL 2000 Profiler, that filtering on DatabaseID was more reliable than filtering on DatabaseName.  Even though I’m now running SQL 2008, that habit sticks with me).  Still no results other than the Login.  Very weird! Finally, I decided to run Profiler with no filtering and discovered that that lines which represent my stored procedure and its T-SQL commands are all marked with DatabaseID = 1, which is Master.  Why in the world would that be?  My procedure is definitely in the application database, and not in Master, and there is nothing funny about the call to the procedure evident in Profiler (i.e. it is not called as MyAppDB.dbo.MyProcName, but rather just dbo.MyProcName).  There must be something funny with the way the Entity Framework is wrapping this call, and I don’t like it…I don’t like it one bit.  My primary PROD server contains 40+ databases on it, and when I need to profile something, I expect to be able to filter based on DatabaseID (for the record, I displayed DatabaseName in my results, too, and it also shows Master). I find the same pattern of everything except the Login showing up as being in Master when I run my version that uses standard LINQ to Entities instead of stored procedures, so that suggests it is not my code, but rather something funny with SQL Server 2008 Profiler or the Entity Framework. If you have any ideas about why this might be so, please comment below.

• How to pad number with leading zero with C#

  - by Jalpesh P. Vadgama

  Recently I was working with a project where I was in need to format a number in such a way which can apply leading zero for particular format.  So after doing such R and D I have found a great way to apply this leading zero format. I was having need that I need to pad number in 5 digit format. So following is a table in which format I need my leading zero format. 1-> 00001 20->00020 300->00300 4000->04000 50000->5000 So in the above example you can see that 1 will become 00001 and 20 will become 00200 format so on. So to display an integer value in decimal format I have applied interger.Tostring(String) method where I have passed “Dn” as the value of the format parameter, where n represents the minimum length of the string. So if we pass 5 it will have padding up to 5 digits. So let’s create a simple console application and see how its works. Following is a code for that. using System; namespace LeadingZero { class Program { static void Main(string[] args) { int a = 1; int b = 20; int c = 300; int d = 4000; int e = 50000; Console.WriteLine(string.Format("{0}------>{1}",a,a.ToString("D5"))); Console.WriteLine(string.Format("{0}------>{1}", b, b.ToString("D5"))); Console.WriteLine(string.Format("{0}------>{1}", c, c.ToString("D5"))); Console.WriteLine(string.Format("{0}------>{1}", d, d.ToString("D5"))); Console.WriteLine(string.Format("{0}------>{1}", e, e.ToString("D5"))); Console.ReadKey(); } } } As you can see in the above code I have use string.Format function to display value of integer and after using integer value’s  ToString method. Now Let’s run the console application and following is the output as expected. Here you can see the integer number are converted into the exact output that we requires. That’s it you can see it’s very easy. We have written code in nice clean way and without writing any extra code or loop. Hope you liked it. Stay tuned for more.. Till than happy programming.

• JavaFX, Google Maps, and NetBeans Platform

  - by Geertjan

  Thanks to a great new article by Rob Terpilowski, and other work and research he describes in that article, it's now trivial to introduce a map component to a NetBeans Platform application. Making use of the GMapsFX library, as described in Rob's article, which provides a JavaFX API for Google Maps, you can very quickly knock this application together. Click to enlarge the image. Here's all the code (from Rob's article): @TopComponent.Description( preferredID = "MapTopComponent", persistenceType = TopComponent.PERSISTENCE_ALWAYS ) @TopComponent.Registration(mode = "editor", openAtStartup = true) @ActionID(category = "Window", id = "org.map.MapTopComponent") @ActionReference(path = "Menu/Window" /*, position = 333 */) @TopComponent.OpenActionRegistration( displayName = "#CTL_MapWindowAction", preferredID = "MapTopComponent" ) @NbBundle.Messages({ "CTL_MapWindowAction=Map", "CTL_MapTopComponent=Map Window", "HINT_MapTopComponent=This is a Map window" }) public class MapWindow extends TopComponent implements MapComponentInitializedListener { protected GoogleMapView mapComponent; protected GoogleMap map; private static final double latitude = 52.3667; private static final double longitude = 4.9000; public MapWindow() { setName(Bundle.CTL_MapTopComponent()); setToolTipText(Bundle.HINT_MapTopComponent()); setLayout(new BorderLayout()); JFXPanel panel = new JFXPanel(); Platform.setImplicitExit(false); Platform.runLater(() -> { mapComponent = new GoogleMapView(); mapComponent.addMapInializedListener(this); BorderPane root = new BorderPane(mapComponent); Scene scene = new Scene(root); panel.setScene(scene); }); add(panel, BorderLayout.CENTER); } @Override public void mapInitialized() { //Once the map has been loaded by the Webview, initialize the map details. LatLong center = new LatLong(latitude, longitude); MapOptions options = new MapOptions(); options.center(center) .mapMarker(true) .zoom(9) .overviewMapControl(false) .panControl(false) .rotateControl(false) .scaleControl(false) .streetViewControl(false) .zoomControl(false) .mapType(MapTypeIdEnum.ROADMAP); map = mapComponent.createMap(options); //Add a couple of markers to the map. MarkerOptions markerOptions = new MarkerOptions(); LatLong markerLatLong = new LatLong(latitude, longitude); markerOptions.position(markerLatLong) .title("My new Marker") .animation(Animation.DROP) .visible(true); Marker myMarker = new Marker(markerOptions); MarkerOptions markerOptions2 = new MarkerOptions(); LatLong markerLatLong2 = new LatLong(latitude, longitude); markerOptions2.position(markerLatLong2) .title("My new Marker") .visible(true); Marker myMarker2 = new Marker(markerOptions2); map.addMarker(myMarker); map.addMarker(myMarker2); //Add an info window to the Map. InfoWindowOptions infoOptions = new InfoWindowOptions(); infoOptions.content("<h2>Center of the Universe</h2>") .position(center); InfoWindow window = new InfoWindow(infoOptions); window.open(map, myMarker); } } Awesome work Rob, will be useful for many developers out there.

• Caching no .NET Framework 4.0

  - by anobre

  Olá pessoal, como estão? Hoje vou apresentar uma mudança interessante sobre caching, em comparação com versões anteriores. Introdução A versão 4.0 da plataforma .NET trouxe uma mudança estrutural esperada para os recursos de Cache. Nas versão 3.5 (até SP1), a plataforma fornecia uma implementação do Cache através do namespace System.Web.Caching. Nas versões anteriores o cache estava disponível no namespace System.Web, o que criada uma dependência com as classes do ASP.NET. Neste novo framework, o namespace System.Runtime.Caching reúne toda a API necessária para criar todas as tarefas comuns ao ASP.NET Caching de versões anteriores. System.Runtime.Caching e MemoryCache Tudo que precisamos para trabalhar com cache, em aplicações Web ou não, está reunido no namespace System.Runtime.Caching. A unidade básica de trabalho é a classe abstrata ObjectCache, que fornece a base para criar implementações customizadas de cache. E como é de se esperar, a classe MemoryCache é a implementação da classe abstrata ObjectCache para armazenamento das informações em memória. public class MemoryCache : ObjectCache, IEnumerable, IDisposable A utilização do cache é muito simples, bem parecida com o modelo anterior: ObjectCache cache = MemoryCache.Default; string fileContents = cache["filecontents"] as string; if (fileContents == null) { CacheItemPolicy policy = new CacheItemPolicy(); List<string> filePaths = new List<string>(); filePaths.Add("c:\\cache\\example.txt"); policy.ChangeMonitors.Add(new HostFileChangeMonitor(filePaths)); // Fetch the file contents. fileContents = File.ReadAllText("c:\\cache\\example.txt"); cache.Set("filecontents", fileContents, policy); } Label1.Text = fileContents; Extendendo o Cache É possível customizar todo mecanismo de cache através de várias abordagens. ScottGu escreveu sobre isto, que você pode acessar através deste link. Conclusão Algo muito esperado em versões anteriores, finalmente o cache está disponível sem criar relacionamento com assemblies exclusivamente Web. Perfeito para quem desenvolve outros tipos de aplicação, usufruindo deste recurso sem carregar código desnecessário. Abraços!

• View HTML Tags and Webpage Combined in Firefox

  - by Asian Angel

  Do you want an easier way to see a webpage’s html tags without viewing the source code in a separate window? Now you can view the webpage and tags combined in the same window using the X-Ray extension for Firefox. Before Usually if you want to see the source code behind a webpage you have to view it in a separate window. If you are only interested in a specific section then you have to search through the entire set of code just to find what you are looking for. After The X-Ray extension will let you see the document’s tags (including class and ID names) “side by side” with the webpage in the same tab. You can use either the context menu or the tools menu to access the X-Ray command. Here is the same webpage section shown in the first screenshot above. It may look a little odd at first until you get used to seeing both together. Note: You can return the webpage to its’ normal view by either clicking on the X-Ray command again or refreshing the page. The code for part of the sidebar on the same webpage… Followed by one of the sets of links at the end. Looking at another example suppose you are interested in how part of the main feed is set up. Being able to see how a particular element is set up directly in the webpage is certainly better than searching through the entire page of code. Conclusion If you design webpages and want an easy way to see how someone else’s website is coded then you may want to give this extension a try.

• Separating physics and game logic from UI code

  - by futlib

  I'm working on a simple block-based puzzle game. The game play consists pretty much of moving blocks around in the game area, so it's a trivial physics simulation. My implementation, however, is in my opinion far from ideal and I'm wondering if you can give me any pointers on how to do it better. I've split the code up into two areas: Game logic and UI, as I did with a lot of puzzle games: The game logic is responsible for the general rules of the game (e.g. the formal rule system in chess) The UI displays the game area and pieces (e.g. chess board and pieces) and is responsible for animations (e.g. animated movement of chess pieces) The game logic represents the game state as a logical grid, where each unit is one cell's width/height on the grid. So for a grid of width 6, you can move a block of width 2 four times until it collides with the boundary. The UI takes this grid, and draws it by converting logical sizes into pixel sizes (that is, multiplies it by a constant). However, since the game has hardly any game logic, my game logic layer [1] doesn't have much to do except collision detection. Here's how it works: Player starts to drag a piece UI asks game logic for the legal movement area of that piece and lets the player drag it within that area Player lets go of a piece UI snaps the piece to the grid (so that it is at a valid logical position) UI tells game logic the new logical position (via mutator methods, which I'd rather avoid) I'm not quite happy with that: I'm writing unit tests for my game logic layer, but not the UI, and it turned out all the tricky code is in the UI: Stopping the piece from colliding with others or the boundary and snapping it to the grid. I don't like the fact that the UI tells the game logic about the new state, I would rather have it call a movePieceLeft() method or something like that, as in my other games, but I didn't get far with that approach, because the game logic knows nothing about the dragging and snapping that's possible in the UI. I think the best thing to do would be to get rid of my game logic layer and implement a physics layer instead. I've got a few questions regarding that: Is such a physics layer common, or is it more typical to have the game logic layer do this? Would the snapping to grid and piece dragging code belong to the UI or the physics layer? Would such a physics layer typically work with pixel sizes or with some kind of logical unit, like my game logic layer? I've seen event-based collision detection in a game's code base once, that is, the player would just drag the piece, the UI would render that obediently and notify the physics system, and the physics system would call a onCollision() method on the piece once a collision is detected. What is more common? This approach or asking for the legal movement area first? [1] layer is probably not the right word for what I mean, but subsystem sounds overblown and class is misguiding, because each layer can consist of several classes.

• Just another web startup - platform comparison

  - by Holland

  I'm looking to do a web startup which involves something along the lines of an ecommerce site, yet a little more in depth than that. While it's something that I would rather not go into detail with in terms of the initial idea, I can specify (on a basic level) what would be required of the website. If you have any observations or opinions derived from personal experience, which relate to what you see here, I'd appreciate it if you could share these. Paypal's API interaction (definitely). From what I've read about their API, integration with it into their website is VERY expensive, so I'd probably hold off on that until I've (hopefully) generated money and write my own simple credit-card interaction system. SQL Backend (obviously) PostgreSQL seems like a pretty good choice, as from what I've read, it's structure is a bit more "object-oriented" than, say, MySQL. Then again, I've used MySQL before and haven't had much problem with it whatsoever. Would it be worth learning PostgreSQL for this purpose? Java or .Net implementation (Preferably Mono, so I can use .Net while hosting the website using Apache). The reason for this is because, frankly, while I know PHP is a great platform to develop websites with, I hate developing with it. Before someone chimes in and flames me for saying that, note that I have nothing against the language, I just don't like it for my purposes. While Mono may be good to go with, I'm aware that ASP.Net MVC 3 hasn't been released for Mono yet, which may be a pain to work with, without their Razor syntax. Ontop of that, it seems Java is completely FULL of class libraries which deal with web development, that can be downloaded from the web. If anyone has any experience with these, I'd appreciate if that were posted. From what I've read about Spring and Struts2, they seem to be the best out there - especially since they're (AFAIK) MVC. I've considered Python and Django, which do seem REALLY nice, but I don't know much Python, and I'd rather start with something that I already know (language-wise; not framework-wise) than dive into learning a language AND a new framework. I'd REALLY like to be able to host my website via Apache, rather than using Windows Server or anything like that, as, frankly, I hate their setup. I'm not dissing it in any way, shape, or form, I'm just saying I dislike it. <3 terminal config. If there is a good reason to with Windows Server, however, I'd be willing to learn it. C# has a lot of things that Java appears not to have, including Delegates, unsigned types, and LINQ. Is there anything that Java has which can counter these?

• Steps to deploying on Windows Azure

  - by Vincent Grondin

  Alright, these steps might be a little detailed and of few might not be necessary but still it's a pretty accurate road map to deploying on azure...     1)     Open you solution 2)      Rebuild ALL 3)      Right click on your Azure project and click "Publish" 4)      It should open a windows explorer window with your package to be uploaded (.cspkg ) and its associated configuration (.cscfg) to be uploaded too.  Keep it open, you'll need that path later on... 5)      It should also open a browser asking you to login to your passport account, please do so. 6)      After this you will be redirected to the Azure Portal where you will see your Azure Project Name below the « Projet Name » section.  Click on it. 7)      Then you should be redirected to a detailed view of your account on Azure where you will create a new service by clicking the hyperlink on the top right corner. 8)      Choose the right service type for you, most likely the "Hosted Service" type 9)      Choose a « Label » name and click « next » 10)   Choose a name for your service and validate that the name is available in the cloud by clicking the "Check Availability" button 11)   At the bottom of this same page, you can choose to create a group for your service, use no group or join an existing group.  Creating a group means that all applications that belong to the same group will see no cost to exchanging data between other applications of the same group.  Most of the time when you create a single application, creating a group is not necessary.  You should choose a region that's close to your own region. 12)   On the next window, you should see a "Production" environment and a "Staging" environment.  Beware because "Staging" and "Production" are two different environments in the cloud and applications in "Staging" even when not runing do continue to rack in charges...  Choose an environment and click "Deploy". 13)   In the following window, browse to the path where your cspkg resides and then do the same thing with your cscfg file.  Choose a name for your Label,  and click "Deploy"... 14)   From now on, the clock is ticking and unless you have free Azure hours, your credit card is being billed… 15)   Click on the « Run » button to start your application 16)   Be patient.... be very patient… 17)   Once your application has finished starting, you should see a GREEN circle on the left side of the screen indicating that your application is READY.  Click the URL to test your application and remember that if your application is a service, you have to hit the "svc" class behind the link you see there.  Something in the likes of http://testvince2.cloudapp.net/service1.svc  (this is a fictional link) 18)   Hopefully your application will show up or in the case of a service, you will see your service's wsdl meaning that everything is working fine. Happy cloud computing all!

• O the Agony - Merging Scrum and Waterfall

  - by John K. Hines

  If there's nothing else to know about Scrum (and Agile in general), it's this: You can't force a team to adopt Agile methods.  In all cases, the team must want to change. Well, sure, you could force a team.  But it's going to be a horrible, painful process with a huge learning curve made even steeper by the lack of training and motivation on behalf of the team.  On a completely unrelated note, I've spent the past three months working on a team that was formed by merging three separate teams.  One of these teams has been adopting and using Agile practices like Scrum since 2007, the other was in continuous bug fix mode, releasing on average one new piece of software per year using semi-Waterfall methods.  In particular, one senior developer on the Waterfall team didn't see anything in Agile but overhead. Fast forward through three months of tension, passive resistance, process pushback, and you have seven people who want to change and one who explicitly doesn't.  It took two things to make Scrum happen: The team manager took a class called "Agile Software Development using Scrum". The team lead explained the point of Agile was to reduce the workload of the senior developer, with another senior developer and the manager present. It's incredible to me how a single person can strongly influence the direction of an entire team.  Let alone if Scrum comes down as some managerial decree onto a functioning team who have no idea what it is.  Pity the fool. On the bright side, I am now an expert at drawing Visio process flows.  And I have some gentle advice for any first-level managers: If you preside over a team process change, it's beneficial to start the discussion on how the team will work as early as possible.  You should have a vision for this and guide the discussion, even if decisions are weeks away.  Don't always root for the underdog.  It's been my experience that managers who see themselves as compassionate and caring spend a great deal of time understanding and advocating for the one person on the team who feels left out.  Remember that by focusing on this one person you risk alienating the rest of the team, allow tension to build, and delay the resolution of the problem. My way would have been to decree Scrum, force all of my processes on everyone else, and use the past three months ironing out the kinks.  Which takes us all the way back to point number one.

• on coding style

  - by user12607414

  I vastly prefer coding to discussing coding style, just as I would prefer to write poetry instead of talking about how it should be written. Sometimes the topic cannot be put off, either because some individual coder is messing up a shared code base and needs to be corrected, or (worse) because some officious soul has decided, "what we really need around here are some strongly enforced style rules!" Neither is the case at the moment, and yet I will venture a post on the subject. The following are not rules, but suggested etiquette. The idea is to allow a coherent style of coding to flourish safely and sanely, as a humane, inductive, social process. Maxim M1: Observe, respect, and imitate the largest-scale precedents available. (Preserve styles of whitespace, capitalization, punctuation, abbreviation, name choice, code block size, factorization, type of comments, class organization, file naming, etc., etc., etc.) Maxim M2: Don't add weight to small-scale variations. (Realize that Maxim M1 has been broken many times, but don't take that as license to create further irregularities.) Maxim M3: Listen to and rely on your reviewers to help you perceive your own coding quirks. (When you review, help the coder do this.) Maxim M4: When you touch some code, try to leave it more readable than you found it. (When you review such changes, thank the coder for the cleanup. When you plan changes, plan for cleanups.) On the Hotspot project, which is almost 1.5 decades old, we have often practiced and benefited from such etiquette. The process is, and should be, inductive, not prescriptive. An ounce of neighborliness is better than a pound of police-work. Reality check: If you actually look at (or live in) the Hotspot code base, you will find we have accumulated many annoying irregularities in our source base. I suppose this is the normal condition of a lived-in space. Unless you want to spend all your time polishing and tidying, you can't live without some smudge and clutter, can you? Final digression: Grammars and dictionaries and other prescriptive rule books are sometimes useful, but we humans learn and maintain our language by example not grammar. The same applies to style rules. Actually, I think the process of maintaining a clean and pleasant working code base is an instance of a community maintaining its common linguistic identity. BTW, I've been reading and listening to John McWhorter lately with great pleasure. (If you end with a digression, is it a tail-digression?)

• SharePoint 2010 Field Expression Builder

  - by Ricardo Peres

  OK, back to two of my favorite topics, expression builders and SharePoint. This time I wanted to be able to retrieve a field value from the current page declaratively on the markup so that I can assign it to some control’s property, without the need for writing code. Of course, the most straight way to do it is through an expression builder. Here’s the code: 1: [ExpressionPrefix("SPField")] 2: public class SPFieldExpressionBuilder : ExpressionBuilder 3: { 4: #region Public static methods 5: public static Object GetFieldValue(String fieldName, PropertyInfo propertyInfo) 6: { 7: Object fieldValue = SPContext.Current.ListItem[fieldName]; 8:  9: if (fieldValue != null) 10: { 11: if ((fieldValue is IConvertible) && (typeof(IConvertible).IsAssignableFrom(propertyInfo.PropertyType) == true)) 12: { 13: if (propertyInfo.PropertyType.IsAssignableFrom(fieldValue.GetType()) != true) 14: { 15: fieldValue = Convert.ChangeType(fieldValue, propertyInfo.PropertyType); 16: } 17: } 18: } 19:  20: return (fieldValue); 21: } 22:  23: #endregion 24:  25: #region Public override methods 26: public override Object EvaluateExpression(Object target, BoundPropertyEntry entry, Object parsedData, ExpressionBuilderContext context) 27: { 28: return (GetFieldValue(entry.Expression, entry.PropertyInfo)); 29: } 30:  31: public override CodeExpression GetCodeExpression(BoundPropertyEntry entry, Object parsedData, ExpressionBuilderContext context) 32: { 33: if (String.IsNullOrEmpty(entry.Expression) == true) 34: { 35: return (new CodePrimitiveExpression(String.Empty)); 36: } 37: else 38: { 39: return (new CodeMethodInvokeExpression(new CodeMethodReferenceExpression(new CodeTypeReferenceExpression(this.GetType()), "GetFieldValue"), new CodePrimitiveExpression(entry.Expression), new CodePropertyReferenceExpression(new CodeArgumentReferenceExpression("entry"), "PropertyInfo"))); 40: } 41: } 42:  43: #endregion 44:  45: #region Public override properties 46: public override Boolean SupportsEvaluate 47: { 48: get 49: { 50: return (true); 51: } 52: } 53: #endregion 54: } You will notice that it will even try to convert the field value to the target property’s type, through the use of the IConvertible interface and the Convert.ChangeType method. It must be placed on the Global Assembly Cache or you will get a security-related exception. The other alternative is to change the trust level of your web application to full trust. Here’s how to register it on Web.config: 1: <expressionBuilders> 2: <!-- ... --> 3: <add expressionPrefix="SPField" type="MyNamespace.SPFieldExpressionBuilder, MyAssembly, Culture=neutral, Version=1.0.0.0, PublicKeyToken=29186a6b9e7b779f" /> 4: </expressionBuilders> And finally, here’s how to use it on an ASPX or ASCX file inside a publishing page: 1: <asp:Label runat="server" Text="<%$ SPField:Title %>"/>
