  • Mutation Testing

    You may have a twinge of doubt when your code passes all its unit tests. They might say that the code is OK, but if the code is definitely incorrect, will the unit tests fail? Mutation Testing is a relatively simple, but ingenious, way of checking that your tests will spot the fact that your code is malfunctioning. It is definitely something that every developer should be aware of.

  • adding custom SSIS transformation to visual studio toolbox fails

    - by ryangaraygay
    Just very recently I encountered an issue in deploying a custom SSIS component assembly which turns out to be a relative "no-brainer" error if only the clues were more straightforward. Basically after deploying the assembly I could not find my component listed in the "SSIS Data Flow Items" tab list.It turns out that the assembly containing the component just had missing or referenced the incorrect assemblies.I have outlined the steps I took that guided me on the right direction on this blog post of mine : adding custom SSIS transformation to visual studio toolbox fails

  • Installing Ubuntu with Windows installer on Windows 8 machine

    - by tpmeera
    I have a Windows 8 Ultrabook. I downloaded Ubuntu (release 12.04) and installed using the Windows installer (Wubi). On rebooting at the end of the installation, I get the Windows boot screen asking if I want to boot into Windows 8 or Ubuntu. I select Ubuntu, and I get an error message that says Ubuntu is missing a boot file or has errors. Please let me know how to fix, or if my procedure is incorrect.

  • Asset missing problem XNA

    - by ChocoMan
    I'm using VS2010 with XNA 4.0 and I'm trying to load an FBX model with texture on the screen. The problem I'm having is this error: Missing Asset: C:\Users\ChocoMan\Documents\Visual Studio 2010\Projects\XNAGame\Documents\Visual Studio\Projects\XNAGame\XNAGameContent\Textures\texture.bmp but the actual path to the texture is C:\Users\ChocoMan\Documents\Visual Studio\Projects\XNAGame\XNAGameContent\Textures\texture.bmp Also, when I linked the texture in Maya, I used the above address. Does anyone know why VS is looking for an incorrect address that doesnt exist?

  • SQL Server v.Next (Denali) : Metadata enhancements

    - by AaronBertrand
    In my previous job, we had several cases where schema changes or incorrect developer assumptions in the middle tier or application logic would lead to type mismatches. We would have a stored procedure that returns a BIT column, but then change the procedure to have something like CASE WHEN <condition> THEN 1 ELSE 0 END. In this case SQL Server would return an INT as a catch-all, and if .NET was expecting a boolean, BOOM. Wouldn't it be nice if the application could check the result set of the...(read more)

  • How to do directional per fragment lighting in world space?

    - by user
    I am attempting to create a GLSL shader for simple, per-fragment directional light. So far, after following many tutorials, I have continually ran into the issue: my light is specified in world coordinates, however, the shader treats the light's position as being in eye space, thus, the light direction changes when I move the camera. My question is, how to I transform a directional light position such as (50, 50, 50, 0) into eye space, or, would doing things this way be the incorrect approach to the problem?

  • Managing Data Growth in SQL Server

    'Help, my database ate my disk drives!'. Many DBAs spend most of their time dealing with variations of the problem of database processes consuming too much disk space. This happens because of errors such as incorrect configurations for recovery models, data growth for large objects and queries that overtax TempDB resources. Rodney describes, with some feeling, the errors that can lead to this sort of crisis for the working DBA, and their solution.

  • Why are textures always square powers of two? What if they aren't?

    - by Keavon
    Why are the resolution of textures in games always a power of two (128x128, 256x256, 512x512, 1024x1024, etc.)? Wouldn't it be smart to save on the game's file size and make the texture exactly fit the UV unwrapped model? What would happen if there was a texture that was not a power of two? Would it be incorrect to have a texture be something like 256x512, or 512x1024? Or would this cause the problems that non-power-of-two textures may cause?

  • After locking the screen in Ubuntu 14.04, password is not accepted, How can it be fixed?

    - by Itai Ganot
    I'm running Ubuntu 14.04 fully updated on my laptop. Since the last update every time I lock the screen (when leaving my room for example) - when I get back and input my password, it is not accepted even though it's the correct password, the error I get is: Password incorrect, please try again I found that clicking the "Switch Account" fixes the issue but it is very annoying, if you know any way to fix it, it would be nice. Thanks in advance

    I am getting a lot of errors in Webmaster Tools and basically there's a lot of links ending like this: mydomainname.com/links.php How can I redirect these links, to shave off this part at the end?

  • why does ubuntu 12.04 remove gparted during the installation?

    - by user09887
    04, and I expanded the progress bar when it was about 3/4 done - it was at the 'remove unnecessary parts from installation' stage. I was thinking that removing gparted was not a good idea, as it is useful for partitioning USB devices - not just the internal hds. Does anyone else think that Ubuntu shouldn't remove gparted? Thanks P.S Sorry if this is posted in the incorrect forum / place. This is my first post to Ubuntu forums. Thanks.

  • Opening / using WUBI after downloading

    - by Jon
    I have no problem downloading WUBI either using Firefox or IE. Either way, however, when I try to run or open it, I get a message to the effect that the file cannot run because the configuration is incorrect and "re-installing the file may help" (which it doesn't - I've tried several times). What am doing wrong ? I am running XP Pro. (Note: my Ubuntu CD works just fine but I want to install Ubuntu inside Windows).

  • Looking for terminology for the relation of a subject and a predicate

    - by kostja
    While writing some predicates for collection filtering I have stumbled over the choice of the right words for the relation of the subject and the predicate (English is a foreign language for me). What I ended up writing was "Subjects matching this predicate..." This seems to be incorrect, since predicates are functions and not regular expressions. But saying "Subjects for which this predicate returns true..." sounds awkward to me as well.. So what would be the correct term?

  • Where should Acceptance tests be written against?

    - by Jonn
    I'm starting to get into writing automated Acceptance tests and I'm quite confused where to write these tests against, specifically what layer in the app. Most examples I've seen are Acceptance tests written against the Domain but how about tests like: Given Incorrect Data When the user submits the form Then Play an Error Beep These seem to be fit for the UI and not for the Domain, or probably even the Service layer.

  • Isometric Collision Detection

    - by Sleepy Rhino
    I am having some issues with trying to detect collision of two isometric tile. I have tried plotting the lines between each point on the tile and then checking for line intercepts however that didn't work (probably due to incorrect formula) After looking into this for awhile today I believe I am thinking to much into it and there must be a easier way. I am not looking for code just some advise on the best way to achieve detection of overlap

  • Unable to set password in IIS 8 for Domain User as ApplicationPool Identity

    - by Niels R.
    I'm trying to set a Domain User account as ApplicationPool Identity in IIS 8 (Windows 2012). When trying this using the IIS Management Console I always get an error: Value does not fall within the expected range.

  • Can't Access TFS 2010 Beta 2 from Visual Studio 2010 Beta 2 when domain joined

    - by Brian Sullivan
    I'm experimenting with an installation of TFS 2010 Beta 2 on a virtual machine under VirtualBox running Windows Server 2008. When I've got the server in a workgroup, I can connect to it from Visual Studio just fine, as long as I provide credentials for a local user on the server machine when prompted by the "Connect to Team Foundation Server" dialog. The desktop I'm running Visual Studio on is joined to a domain. However, when I join the server to the domain, I can no longer connect to it from Visual Studio. I get a pretty generic error message: "TF31002 - Unable to connect to team foundation server". It gives me several different possible problems, including an incorrect address or an incorrect username and password. I've already added the domain Windows identity with which I'm logged on the the desktop to the TFS Admins group on the server, so I don't think it's a username/password problem. I've also tried putting the literal IP address of the server in the dialog address box instead of the machine name, but still no dice. I made sure that network discovery was enabled on the server, too, and can navigate to "\\webserver2008" in Windows Explorer without any problems. Shouldn't be a firewall problem, since the TFS install creates the appropriate exceptions in Windows Firewall. It's all a bit confusing, since it seems to work when the server is in a workgroup. Note: I'm a dev, not an admin, so there are many subtleties of server administration with which I'm not familiar. Please make no assumptions about what I may or may not have tried; what may be obvious to you may have never occurred to me. Thanks in advance!
