• Having a problem with texturing vertices in WebGL, think parameters are off in the image?

  - by mathacka

  I'm having a problem texturing a simple rectangle in my WebGL program, I have the parameters set as follows: gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, textureImage); I'm using this image: On the properties of this image it says it's 32 bit depth, so that should take care of the gl.UNSIGNED_BYTE, and I've tried both gl.RGBA and gl.RGB to see if it's not reading the transparency. It is a 32x32 pixel image, so it's power of 2. And I've tried almost all the combinations of formats and types, but I'm not sure if this is the answer or not. I'm getting these two errors in the chrome console: INVALID_VALUE: texImage2D: invalid image (index):101 WebGL: drawArrays: texture bound to texture unit 0 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering or is not 'texture complete'. Or the texture is Float or Half Float type with linear filtering while OES_float_linear or OES_half_float_linear extension is not enabled. the drawArrays function is simply: "gl.drawArrays(gl.TRIANGLES, 0, 6);" using 6 vertices to make a rectangle.

• Is there a clean separation of my layers with this attempt at Domain Driven Design in XAML and C#

  - by Buddy James

  I'm working on an application. I'm using a mixture of TDD and DDD. I'm working hard to separate the layers of my application and that is where my question comes in. My solution is laid out as follows Solution MyApp.Domain (WinRT class library) Entity (Folder) Interfaces(Folder) IPost.cs (Interface) BlogPosts.cs(Implementation of IPost) Service (Folder) Interfaces(Folder) IDataService.cs (Interface) BlogDataService.cs (Implementation of IDataService) MyApp.Presentation(Windows 8 XAML + C# application) ViewModels(Folder) BlogViewModel.cs App.xaml MainPage.xaml (Contains a property of BlogViewModel MyApp.Tests (WinRT Unit testing project used for my TDD) So I'm planning to use my ViewModel with the XAML UI I'm writing a test and define my interfaces in my system and I have the following code thus far. [TestMethod] public void Get_Zero_Blog_Posts_From_Presentation_Layer_Returns_Empty_Collection() { IBlogViewModel viewModel = _container.Resolve<IBlogViewModel>(); viewModel.LoadBlogPosts(0); Assert.AreEqual(0, viewModel.BlogPosts.Count, "There should be 0 blog posts."); } viewModel.BlogPosts is an ObservableCollection<IPost> Now.. my first thought is that I'd like the LoadBlogPosts method on the ViewModel to call a static method on the BlogPost entity. My problem is I feel like I need to inject the IDataService into the Entity object so that it promotes loose coupling. Here are the two options that I'm struggling with: Not use a static method and use a member method on the BlogPost entity. Have the BlogPost take an IDataService in the constructor and use dependency injection to resolve the BlogPost instance and the IDataService implementation. Don't use the entity to call the IDataService. Put the IDataService in the constructor of the ViewModel and use my container to resolve the IDataService when the viewmodel is instantiated. So with option one the layers will look like this ViewModel(Presentation layer) - Entity (Domain layer) - IDataService (Service Layer) or ViewModel(Presentation layer) - IDataService (Service Layer)

• Decal implementation

  - by dreta

  I had issues finding information about decals, so maybe this question will help others. The implementation is for a forward renderer. Could somebody confirm if i got decal implementation right? You define a cube of any dimension that'll define the projection volume in common space. You check for triangle intersection with the defined cube to recieve triangles that the projection will affect. You clip these triangles and save them. You then use matrix tricks to calculate UV coordinates for the saved triangles that'll reference the texture you're projecting. To do this you take the vectors representing height, width and depth of the cube in common space, so that f.e. the bottom left corner is the origin. You put that in a matrix as the i, j, k unit vectors, set the translation for the cube, then you inverse this matrix. You multiply the vertices of the saved triangles by this matrix, that way you get their coordinates inside of a 0 to 1 size cube that you use as the UV coordinates. This way you have the original triangles you're projecting onto and you have UV coordinates for them (the UV coordinates are referencing the texture you're projecting). Then you rerender the saved triangles onto the scene and they overwrite the area of projection with the projected image. Now the questions that i couldn't find answers for. Is the last point right? I've never done software clipping, but it seems error prone enough, due to limited precision, that the'll be some z fighting occuring for the projected texture. Also is the way of getting UV coordinates correct?

• How to Add Your Gmail Account to Outlook 2013 Using IMAP

  - by Lori Kaufman

  If you use Outlook to check and manage your email, you can easily use it to check your Gmail account as well. You can setup your Gmail account to allow you to synchronize email across multiple machines using email clients instead of a browser. We will show you how to use IMAP in your Gmail account so you can synchronize your Gmail account across multiple machines, and then how to add your Gmail account to Outlook 2013. To setup your Gmail account to use IMAP, sign in to your Gmail account and go to Mail. Click the Settings button in the upper, right corner of the window and select Settings from the drop-down menu. On the Settings screen, click Forwarding and POP/IMAP. Scroll down to the IMAP Access section and select Enable IMAP. Click Save Changes at the bottom of the screen. Close your browser and open Outlook. To begin adding your Gmail account, click the File tab. On the Account Information screen, click Add Account. On the Add Account dialog box, you can choose the E-mail Account option which automatically sets up your Gmail account in Outlook. To do this enter your name, email address, and the password for your Gmail account twice. Click Next. The progress of the setup displays. The automatic process may or may not work. If the automatic process fails, select Manual setup or additional server types, instead of E-mail Account, and click Next. On the Choose Service screen, select POP or IMAP and click Next. On the POP and IMAP Account Settings enter the User, Server, and Logon Information. For the Server Information, select IMAP from the Account Type drop-down list and enter the following for the incoming and outgoing server information: Incoming mail server: imap.googlemail.com Outgoing mail server (SMTP): smtp.googlemail.com Make sure you enter your full email address for the User Name and select Remember password if you want Outlook to automatically log you in when checking email. Click More Settings. On the Internet E-mail Settings dialog box, click the Outgoing Server tab. Select the My outgoing server (SMTP) requires authentication and make sure the Use same settings as my incoming mail server option is selected. While still in the Internet E-mail Settings dialog box, click the Advanced tab. Enter the following information: Incoming server: 993 Incoming server encrypted connection: SSL Outgoing server encrypted connection TLS Outgoing server: 587 NOTE: You need to select the type of encrypted connection for the outgoing server before entering 587 for the Outgoing server (SMTP) port number. If you enter the port number first, the port number will revert back to port 25 when you change the type of encrypted connection. Click OK to accept your changes and close the Internet E-mail Settings dialog box. Click Next. Outlook tests the accounts settings by logging into the incoming mail server and sending a test email message. When the test is finished, click Close. You should see a screen saying “You’re all set!”. Click Finish. Your Gmail address displays in the account list on the left with any other email addresses you have added to Outlook. Click the Inbox to see what’s in your Inbox in your Gmail account. Because you’re using IMAP in your Gmail account and you used IMAP to add the account to Outlook, the messages and folders in Outlook reflect what’s in your Gmail account. Any changes you make to folders and any time you move email messages among folders in Outlook, the same changes are made in your Gmail account, as you will see when you log into your Gmail account in a browser. This works the other way as well. Any changes you make to the structure of your account (folders, etc.) in a browser will be reflected the next time you log into your Gmail account in Outlook.

• How to restrict paddle movement using Farseer Physics engine 3.2

  - by brainydexter

  I am new to using Farseer Physics Engine 3.2(FPE), so please bear with my questions. Also, since FPE 3.2 is based on Box2D, I have been reading Box2D manual and pieces of code scattered in samples to better understand terminology and usage. Pong is usually my testbed whenever I try to do something new. Here is one of the issue I am running into: How can I restrict paddles to move only along Y axis, because the ball comes in and knocks off the paddles and everything floats in space afterwards ? (Box = Rectangle and ball = circle) I know MKS is the unit system, but is there a recommendation for sizes/position to be used ? I know this is a very generic question, but it would be good to know a simple set of values that one could use for making a game as simple as pong. Between box2d and FPE, I have some doubts: what is the recommended way of making a body in FPE ? world.CreateBody() does not exist in FPE Box2d manual recommends never to "new" body(since Box2D uses Small Object allocators), so is there a recommended way in Farseer to create a body (apart from factories) ? In box2d, it is recommended to keep a track of the body object, since it is also the parent to fixture(s). Why is it that in most of the examples, the fixture object is tracked ? Is there a reason why body is not tracked ? Thanks

• Finding the normals of an oriented bounding box?

  - by Milo

  Here is my problem. I'm working on the physics for my 2D game. All objects are oriented bounding boxes (OBB) based on the separate axis theorem. In order to do collision resolution, I need to be able to get an object out out of the object it is penetrating. To do this I need to find the normal of the face(s) that the other OBB is touching. Example: The small red OBB is a car lets say, and the big OBB is a static building. I need to determine the unit vector that is the normal of the building edge(s) the car is penetrating to get the car out of there. Here are my questions: How do I determine which edges the car is penetrating. I know how to determine the normal of an edge, but how do I know if I need (-dy, dx) or (dy, -dx)? In the case I'm demonstrating the car is penetrating 2 edges, which edge(s) do I use to get it out? Answers or help with any or all of these is greatly appreciated. Thank you

• Code Measuring and Metrics Tools?

  - by David

  I'm in the process of setting up a build server for personal projects. This server will handle all the normal CI stuff, including running large suites of tests (unit, integration, automated UI). While I'm working out the kinks for including code coverage output with MSTest, it occurs to me that there may be lots of tools out there which give me additional metrics other than just code coverage. FxCop comes to mind as an example. Though I'm sure there are others. Anything that can generate useful reportable data and metrics would be good. Whether it's class dependency charts (looking for Law of Demeter violations, for example), analyses of the uses of classes/functions (looking for a function that isn't used in the system other than just the tests, for example), and so on. I'm not sure the right way to formulate the question, since polling questions or "What's your favorite code analysis tool" aren't very good. But I'm essentially just looking for recommendations on what metrics to gather and the tools that can gather them. The eventual vision for something like this is to have the CI server run a bunch of automated tests and analysis tools and track performance metrics over time. Imagine a dashboard full of graphs plotting these metrics over time. The lines should all relatively be at an equilibrium, and if one starts to stray toward the negative then it's an early indication of problems with the code. In the age old struggle to quantify code quality with management, this sounds like a potentially helpful means of doing just that.

• How to search for a tester?

  - by MainMa

  As a freelance developer, a few times I tried to find some testers to be able to let them test my software/web applications. If I try to find them, it's because most of the customers are not intended to hire external testers and don't see why this can benefit to them, so products are UI-untested and buggy. I tried lots of things. Discussion boards for IT people, specific websites for people who search for a job. Every time I clearly precise that I'm looking for product testers. I completely failed to find anybody for this job. I found instead two types of people: Non IT people who try to qualify as testers, but don't have enough skills for that, and don't really know what testing is and how to do it, Programmers, who are skilled as programmers, but not as testers, and who mostly don't understand neither what testing is about (or think it's the same thing as code review, or it consists in writing unit tests). Of course, they submit general programmers resumes, where they describe their high experience in Assembler and C++, but don't tell anything about anything related to the job of a tester. What I'm doing wrong? Isn't it called "tester"? Is there at least a tester job, different from general programming job? Is there any precise requirement to require from each candidate which can eliminate non IT people and general programmers?

• Implementing game rules in a tactical battle board game

  - by Setzer22

  I'm trying to create a game similar to what one would find in a typical D&D board game combat. For mor examples you could think of games like Advance Wars, Fire Emblem or Disgaea. I should say that I'm using design by component so far, but I can't find a nice way to fit components into the part I want to ask. I'm struggling right now with the "game rules" logic. That is, the code that displays the menu, allows the player to select units, and command them, then tells the unit game objects what to do given the player input. The best way I could thing of handling this was using a big state machine, so everything that could be done in a "turn" is handled by this state machine, and the update code of this state machine does different things depending on the state. This approach, though, leads to a large amount of code (anything not model-related) to go into a big class. Of course I can subdivide this big class into more classes, but it doesn't feel modular and upgradable enough. I'd like to know of better systems to handle this in order to be able to upgrade the game with new rules without having a monstruous if/else chain (or switch / case, for that matter). So, any ideas? I'd also like to ask that if you recommend me a specific design pattern to also provide some kind of example or further explanation and not stick to "Yeah you should use MVC and it'll work".

• Is this kind of Design by Contract useless?

  - by Charlie Pigarelli

  I've just started informatics university and I'm attending a programming course about C(++). The programming professor prefers to teach very few things (in 3 month we have just reached the functions topic) and connect every topic with a type of programming design that somehow is similar to the Design by Contract design. Basically what he ask us to do is to write every exercise with comments Pre-conditions, Post-conditions and Invariants that should prove the correctness of each program we write. But this doesn't make any sense to me. I mean, ok: maybe writing down your thoughts prevent you from doing some mistakes, but if this is all an abstract thing, then if your program intuition is wrong you'll write your program wrong and then you'll also write pre and post conditions wrong probably auto convincing your self about its correctness. Most of the time, both me and other students have written programs that seemed ok and that had correct pre and post condition too. But at the moment of testing it was just completely wrong. I had some experience before this course of programming and I had written a lot of line of code before and I found myself comfortably with just writing a program and unit test it. It take less time to accomplish and is less "abstract" than just thinking about what every single piece of your program should do in every case (which is kinda like mentally testing it). Finally, all this pre and post conditions takes me like 80% of the total time of the exercise. It's harder to think about putting down this pre and post correct than to write the program itself. Since we are like the only course of the only university probably in the entire world that makes this things, could someone please tell me how should I manage this thing? Am I right thinking that this doesn't worth anything? Should I change university? (there are like double of the people attending that course and it seems that usually very few people passes the exam the first year). Should I convince myself it's method is right?

• Developer Preview available for the Java Access Bridge is now included in Java SE 7 Update 6

  - by Ragini Prasad

  The Java Access Bridge product is now being included with Java SE 7u6. Manual installation of the Java Access Bridge will no longer be required. All Access Bridge files will be automatically installed by the JRE and the JDK.             The Developer Preview for this feature is now available and can be downloaded from http://jdk7.java.net/download.html.            By default, the Java Access Bridge is disabled. In order to use the Java Access Bridge, enable it using the steps mentioned below and test your applications for accessibility.             Enable the Java Access Bridge: Use one of these mechanism:             1. Ease Of Access control panel.     On Windows Vista and later the Java Access Bridge can be enabled     from Ease of Access Center.     Select "Use the computer without a display". In "Other programs     installed" section , select the check box to     "Enable Java Access Bridge" and apply. 2. Or run the following command in the Command Window.     %JRE_HOME%\bin\jabswitch -enable Note: You must restart your Assistive Technology software and Java application after enabling the bridge.             Test the Java Access Bridge: 1. Enable the Java Access Bridge as described above. 2. Run an Assistive Technology that supports the Java Access Bridge. 3. Run a Java application. Ensure that the Assistive Technology  reads    the values of your application. Disable the Java Access Bridge:             Run the following command from the Command Window.     %JRE_HOME%\bin\jabswitch -disable                 Note: The Ease Of Access control panel cannot be used to disable the bridge. You must use jabswitch from the Command window to disable the Java Access Bridge.

• How to handle growing QA reporting requirements?

  - by Phillip Jackson

  Some Background: Our company is growing very quickly - in 3 years we've tripled in size and there are no signs of stopping any time soon. Our marketing department has expanded and our IT requirements have as well. When I first arrived everything was managed in Dreamweaver and Excel spreadsheets and we've worked hard to implement bug tracking, version control, continuous integration, and multi-stage deployment. It's been a long hard road, and now we need to get more organized. The Problem at Hand: Management would like to track, per-developer, who is generating the most issues at the QA stage (post unit testing, regression, and post-production issues specifically). This becomes a fine balance because many issues can't be reported granularly (e.g. per-url or per-"page") but yet that's how Management would like reporting to be broken down. Further, severity has to be taken into account. We have drafted standards for each of these areas specific to our environment. Developers don't want to be nicked for 100+ instances of an issue if it was a problem with an include or inheritance... I had a suggestion to "score" bugs based on severity... but nobody likes that. We can't enter issues for every individual module affected by a global issue. [UPDATED] The Actual Questions: How do medium sized businesses and code shops handle bug tracking, reporting, and providing useful metrics to management? What kinds of KPIs are better metrics for employee performance? What is the most common way to provide per-developer reporting as far as time-to-close, reopens, etc.? Do large enterprises ignore the efforts of the individuals and rather focus on the team? Some other questions: Is this too granular of reporting? Is this considered 'blame culture'? If you were the developer working in this environment, what would you define as a measureable goal for this year to track your progress, with the reward of achieving the goal a bonus?

• Copying files to zfs mountpoint doesn't work - the files aren't actually copied to the other filesystem,

  - by user113904

  I have 3 x 4 TB disks in a NAS that I want to group together and access as if they were one whole 'unit' of some kind. I also have a 250GB disk containing the OS - this is full of films and tv shows currently. I thought zfs sounded good so I created a raidz zpool, after installing the ppa sudo zpool create store raidz /dev/sdb /dev/sdc /dev/sdd and set the mountpoint to /mnt/store sudo zfs set mountpoint=/mnt/store /store checked it was successful - I think it was sudo zfs list NAME USED AVAIL REFER MOUNTPOINT store 266K 7.16T 170K /mnt/store Then I wanted to move over a whole load of files from my home directory. I went to where the to-be-copied folder was (called media) and entered sudo cp -R * /mnt/store cp: cannot create directory `/mnt/store/media': No space left on device It seems like it's not copying over to the new filesystem I made (or thought I did). I've never really done this type of thing until a few days ago so may be running before I can walk... is this not the right way to copy files across? I've only used windows before so the idea of mountpoints is a bit mind boggling. I'm using XBMCbuntu 12 beta 2.0 which is based on 12.04. Will retry with normal Ubuntu 12.04 desktop to see if that's the problem. thanks for the help!

• Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work

  - by Dirk

  I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk

• SQL SERVER – Identifying Column Data Type of uniqueidentifier without Querying System Tables

  - by pinaldave

  I love interesting conversations with related to SQL Server. One of my friends Madhivanan always comes up with an interesting point of conversation. Here is one of the conversation between us. I am very confident this blog post will for sure enable you with some new knowledge. Madhi: How do I know if any table has a uniqueidentifier column used in it? Pinal:  I am sure you know that you can do it through some DMV or catalogue views. Madhi: I know that but how can we do that without using DMV or catalogue views? Pinal: Hm… what can I use? Madhi: You can use table name. Pinal: Easy, just say SELECT YourUniqueIdentCol FROM Table. Madhi: Hold on, the question seems to be not clear to you – you do know the name of the column. The matter of the fact, you do not know if the table has uniqueidentifier column. Only information you have is table name. Pinal: Madhi, this seems like you are changing the question when I am close to answer. Madhi: Well, are you clear now? Let me say it again – How do I know if any table has a uniqueidentifier column and what is its value without using any DMV or System Catalogues? Only information you know is table name and you are allowed to return any kind of error if table does not have uniqueidentifier column. Pinal: Do you know the answer? Madhi: Yes. I just wanted to test your knowledge about SQL. Pinal: I will have to think. Let me accept I do not know it right away. Can you share the answer please? Madhi: I won! Here it goes! Pinal: When I have friends like you – who needs enemies? Madhi: (laughter which did not stop for a minute). CREATE TABLE t ( GuidCol UNIQUEIDENTIFIER DEFAULT newsequentialid() ROWGUIDCOL, data VARCHAR(60) ) INSERT INTO t (data) SELECT 'test' INSERT INTO t (data) SELECT 'test1' SELECT $rowguid FROM t DROP TABLE t This is indeed very interesting to me. Please note that this is not the optimal way and there will be many other ways to retrieve uniqueidentifier name and value. What I learned from this was if I am in a rush to check if the table has uniqueidentifier and I do not know the name of the same, I can use SELECT TOP (1) $rowguid and quickly know the name of the column. I can later use the same columnname in my query. Madhi did teach me this new trick. Did you know this? What are other ways to get the check uniqueidentifier column existence in a database?

• Impressions of my ASUS eee slate EP121 - Dual core 4GB, 64GB SSD

  - by tonyrogerson

  This thing is lovely, very nice bluetooth keyboard that has nice feedback on the keypress, there is no mouse but you can use the stylus or get yourself a bluetooth mouse, me, I've opted for a Microsoft ARC mouse which is a delight to use, the USB doors are a pain to open for the first time if like me you don't have any finger nails. It came as a suprise that the slate shows four processors, Dual Core with multi-threading, I didn't really look at the processor I was more interested in the amount of memory and the SSD; you don't get the full 4GB even with the 64 bit version of Windows 7 installed (which I immediately upgraded to Ultimate through my MSDN subscription). The box is extremely responsive - extremely, it loads Winword in literally a second. I've got office 2010 and onenote 2010 on there now; one problem is that on applying all (43) windows updates since the upgrade the machine is still sat on step 3 of 3 on the start up configuring updates screen after about an hour, you can't turn this machine off without using a paper clip to reset it and as I have just found you need a paper clip :). Installing Windows 7 SP1 was effortless. One of the first things I did on it was to reduce the size of the font, by default its set at 125%, my eye sight is ok :) so I've set that back down. Amazon Kindle for the PC works really well, plenty of text on the screen when viewed portrait, the case it comes with also allows the slate to stand up in various positions - portrait, horizontal - seems stable enough. The wireless works well, seems to have a better signal than my other two laptop machines which is good news. The gadget passed the pose test at work :). I use offline files to keep a copy of all my work stuff locally, I'm not sure what it is, well, its probably my server but whenever I try and sync it runs for a couple of minutes then fails with network name no longer contactable, funnily enough its fine from my big laptop so I can only guess this may be a driver type issue on the EP121 itself - very odd and very annoying. I do a lot of presenting and need to plug into a VGA project because most sites that's all that is offered, the EP121 has a mini-hdmi output which is great except for this scenario, hdmi is digital, vga is analogue, you will struggle to find a cost effective solution, I found HDFury and also a device HP do, however, a better solution appears to be getting a USB graphics adapter for instance the one I've ordered is the ClimaxDigital USB 2.0 to DVI,VGA or HDMI Adaptor which gives everything I need - VGA and DVI output and great resolution as well - ok, so fingers crossed because I'm presenting next Wednesday in Edinburgh and not taking my 300kg lenovo w700 (I'm sure my back just sighed in relief) - it certainly works really well on my LED TV, the install was simple - it just works! One of the several reasons for buying this piece of kit was to use it on my LED TV to remote into my main machine to check stuff whilst sat in my living room, also to watch webcasts and lecture videos in comfort away from my office, because of the wireless speed and limitation I'm opting for a USB network adapter from Belkin - that will also allow me to take advantage of my home gigabit network, there are only 2 usb ports on the slate so I'm going to knock up a hub so connecting it in is straight forward and simple, I'm also going to purchase a second power supply so I don't have to faff about with that either.I now have the developer x64 edition of SQL Server 2008 R2, yes everything :) - about 16GB left to play with on the machine now but that will be fine, I'll put AdventureWorks on there so I can play and demo stuff which is all I'm after from this, my development machine is significantly more powerful and meets my storage needs too.Travel test this weekend and next week, I'm in Dundee for my final exam for the masters degree.

• Visual Studio 2010 Best Practices

  - by Etienne Tremblay

  I’d like to thank Packt for providing me with a review version of Visual Studio 2010 Best Practices eBook. In fairness I also know the author Peter having seen him speak at DevTeach on many occasions.  I started by looking at the table of content to see what this book was about, knowing that “best practices” is a real misnomer I wanted to see what they were.  I really like the fact that he starts the book by really saying they are not really best practices but actually recommend practices.  As a Team Foundation Server user I found that chapter 2 was more for the open source crowd and I really skimmed it.  The portion on Branching was well documented, although I’m not a fan of the testing branch myself, but the rest was right on. The section on merge remote changes (bring the outside to you) paradigm is really important and was touched on. Chapter 3 has good solid practices on low level constructs like generics and exceptions. Chapter 4 dives into architectural practices like decoupling, distributed architecture and data based architecture.  DTOs and ORMs are touched on briefly as is NoSQL. Chapter 5 is about deployment and is really a great primer on all the “packaging” technologies like Visual Studio Setup and Deployment (depreciated in 2012), Click Once and WIX the major player outside of commercial solutions.  This is a nice section on how to move from VSSD to WIX this is going to be important in the coming years due to the fact that VS 2012 doesn’t support VSSD. In chapter 6 we dive into automated testing practices, including test coverage, mocking, TDD, SpecDD and Continuous Testing.  Peter covers all those concepts really nicely albeit succinctly. Being a book on recommended practices I find this is really good. I really enjoyed chapter 7 that gave me a lot of great tips to enhance my Visual Studio “experience”.  Tips on organizing projects where good.  Also even though I knew about configurations I like that he put that in there so you can move all your settings to another machine, a lot of people don’t know about that. Quick find and Resharper are also briefly covered.  He touches on macros (depreciated in 2012).  Finally he touches on Continuous Integration a very important concept in today’s ALM landscape. Chapter 8 is all about Parallelization, threads, Async, division of labor, reactive extensions.  All those concepts are touched on and again generalized approaches to those modern problems are giving.       Chapter 9 goes into distributed apps, the most used and accepted practice in the industry for .NET projects the chapter tackles concepts like Scalability, Messaging and Cloud (the flavor of the month of distributed apps, although I think this will stick ;-)).  He also looks a protocols TCP/UDP and how to debug distributed apps.  He touches on logging and health monitoring. Chapter 10 tackles recommended practices for web services starting with implementing WCF services, which goes into all sort of goodness like how to host in IIS or self-host.  How to manual test WCF services, also a section on authentication and authorization.  ASP.NET Web services are also touched on in that chapter All in all a good read, nice tips and accepted practices.  I like the conciseness of the subjects and Peter touches on a lot of things in this book and uses a lot of the current technologies flavors to explain the concepts.   Cheers, ET

• A better way to encourage contributions to OSS

  - by Daniel Cazzulino

  Currently in the .NET world, most OSS projects are available via a NuGet package. Users have a very easy path towards *using* the project right away. But let’s say they encounter some isssue (maybe a bug, maybe a potential improvement) with the library. At this point, going from user to contributor (of a fix, or a good bug repro or even a spike for a new feature) is a very steep and non trivial multi-step process of registering with some open source hosting site (codeplex, github, bitbucket, etc.), learning how to grab the latest sources, build the project, formulate a patch (or fork the code), learn the source control software they use (mercurial, git, svn, tfs), install whatever tools are needed for it, read about the contributors workflow for the project (do you fork &amp; send pull requests? do you just send a patch file? do you just send a snippet? a unit test? etc.), and on, and on, and on. Granted, you may be lucky and already know the source control system the project uses, but in really, I’d say the chances are pretty low. I believe most developers *using* OSS are far from familiar with them, much less with contributing back to various projects. We OSS devs like to be on the cutting edge all the time, ya’ know, always jumping on the new SCC system, the new hosting site, the new agile way of managing work items, bug tracking, code reviews, etc. etc. etc.. But most of our OSS users are largely the “... Read full article

• How to center and scale Silverlight applications using ViewBox control

  - by Jacek Ciereszko

  There are many ways to make your application scalable in Web Browser window and align it in the center. Usually we use two Grid controls to align and panel control (like Canvas) to scale our apps. Not the best solution <UserControl … >     <Grid x:Name="LayoutRoot" Background="White">         <Grid HorizontalAlignment="Center" VerticalAlignment="Center">             <Canvas x:Name="scalePanel" VerticalAlignment="Top" HorizontalAlignment="Center">                 …             </Canvas>         </Grid>     </Grid> </UserControl>               The example above usually works but there are better ways. How? Use ViewBox. ViewBox control contains scale mechanisms with some stretching options. So ViewBox together with Grid control is all what we need to align and scale our applications. Good solution <UserControl … >     <Grid x:Name="LayoutRoot" Background="White">         <Viewbox>             ...         </Viewbox>     </Grid> </UserControl> How to find ViewBox control For those applications created in Silverlight 4, ViewBox is available in plug-in. For applications created in Silverlight 3 you can find it in Microsoft Silverlight Toolkit. Demo Let’s create a simple application that will contain: Button, TextBlock and red Rectangle. It will also have some Margin settings. This application won’t be in the center of window and it will not scale. <UserControl … >     <Grid x:Name="LayoutRoot">         <Grid Margin="100, 50, 100, 20">                 <StackPanel Orientation="Horizontal">                     <Button Width="100" Height="100" Content="test"/>                     <TextBlock Text="Button" Width="100" Height="100" />                     <Rectangle Width="100" Height="100" Fill="Red"/>                 </StackPanel>         </Grid> </Grid> </UserControl>   Run demo: RUN But If we use ViewBox control, we will got centered and always scaled application.    <Grid x:Name="LayoutRoot">         <Viewbox>             <Grid Margin="100, 50, 100, 20">                     <StackPanel Orientation="Horizontal">                         <Button Width="100" Height="100" Content="test"/>                         <TextBlock Text="bottom" Width="100" Height="100" />                         <Rectangle Width="100" Height="100" Fill="Red"/>                     </StackPanel>             </Grid>         </Viewbox>     </Grid> Link to application: RUN (try to resize application’s window) Link to source code: SilverlightCenterApplication.zip References ViewBox for Silverlight 3 http://silverlight.codeplex.com/    Polish version: http://jacekciereszko.pl/2010/05/jak-wysrodkowac-i-skalowac-aplikacje.html Jacek Ciereszko
