  - by Harikrishna

  I want to read the html file.And for that I use System.IO.File.ReadAllText(path).It can read all the html file but there is one file which is not read through this function. I have also used using (StreamReader reader = File.OpenText(fileName)) { text = reader.ReadToEnd(); But still there is same problem. What is the reason can be there ? And for that what can be the solution ? Or any other way to read the file ?

• Configure Forms based authentication in SharePoint 2010

  - by sreejukg

    Configuring form authentication is a straight forward task in SharePoint. Mostly public facing websites built on SharePoint requires form based authentication. Recently, one of the WCM implementation where I was included in the project team required registration system. Any internet user can register to the site and the site offering them some membership specific functionalities once the user logged in. Since the registration open for all, I don’t want to store all those users in Active Directory. I have decided to use Forms based authentication for those users. This is a typical scenario of form authentication in SharePoint implementation. To implement form authentication you require the following A data store where you are storing the users – technically this can be active directory, SQL server database, LDAP etc. Form authentication will redirect the user to the login page, if the request is not authenticated. In the login page, there will be controls that validate the user inputs against the configured data store. In this article, I am going to use SQL server database with ASP.Net membership API’s to configure form based authentication in SharePoint 2010. This article assumes that you have SQL membership database available. I already configured the membership and roles database using aspnet_regsql command. If you want to know how to configure membership database using aspnet_regsql command, read the below blog post. http://weblogs.asp.net/sreejukg/archive/2011/06/16/usage-of-aspnet-regsql-exe-in-asp-net-4.aspx The snapshot of the database after implementing membership and role manager is as follows. I have used the database name “aspnetdb_claim”. Make sure you have created the database and make sure your database contains tables and stored procedures for membership. Create a web application with claims based authentication. This article assumes you already created a web application using claims based authentication. If you want to enable forms based authentication in SharePoint 2010, you must enable claims based authentication. Read this post for creating a web application using claims based authentication. http://weblogs.asp.net/sreejukg/archive/2011/06/15/create-a-web-application-in-sharepoint-2010-using-claims-based-authentication.aspx  You make sure, you have selected enable form authentication, and then selected Membership provider and Role manager name. To make sure you are done with the configuration, navigate to central administration website, from central administration, navigate to the Web Applications page, select the web application and click on icon, you will see the authentication providers for the current web application. Go to the section Claims authentication types, and make sure you have enabled forms based authentication. As mentioned in the snapshot, I have named the membership provider as SPFormAuthMembership and role manager as SPFormAuthRoleManager. You can choose your own names as you need. Modify the configuration files(Web.Config) to enable form authentication There are three applications that needs to be configured to support form authentication. The following are those applications. Central Administration If you want to assign permissions to web application using the credentials from form authentication, you need to update Central Administration configuration. If you do not want to access form authentication credentials from Central Administration, just leave this step.  STS service application Security Token service is the service application that issues security token when users are logging in. You need to modify the configuration of STS application to make sure users are able to login. To find the STS application, follow the following steps Go to the IIS Manager Expand the sites Node, you will see SharePoint Web Services Expand SharePoint Web Services, you can see SecurityTokenServiceApplication Right click SecuritytokenServiceApplication and click explore, it will open the corresponding file system. By default, the path for STS is C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebServices\SecurityToken You need to modify the configuration file available in the mentioned location. The web application that needs to be enabled with form authentication. You need to modify the configuration of your web application to make sure your web application identifies users from the form authentication.   Based on the above, I am going to modify the web configuration. At end of each step, I have mentioned the expected output. I recommend you to go step by step and after each step, make sure the configuration changes are working as expected. If you do everything all together, and test your application at the end, you may face difficulties in troubleshooting the configuration errors. Modifications for Central Administration Web.Config Open the web.config for the Central administration in a text editor. I always prefer Visual Studio, for editing web.config. In most cases, the path of the web.config for the central administration website is as follows C:\inetpub\wwwroot\wss\VirtualDirectories\<port number> Make sure you keep a backup copy of the web.config, before editing it. Let me summarize what we are going to do with Central Administration web.config. First I am going to add a connection string that points to the form authentication database, that I created as mentioned in previous steps. Then I need to add a membership provider and a role manager with the corresponding connectionstring. Then I need to update the peoplepickerwildcards section to make sure the users are appearing in search results. By default there is no connection string available in the web.config of Central Administration. Add a connection string just after the configsections element. The below is the connection string I have used all over the article. <add name="FormAuthConnString" connectionString="Initial Catalog=yourdatabasename;data source=databaseservername;Integrated Security=SSPI;" /> Once you added the connection string, the web.config look similar to Now add membership provider to the code. In web.config for CA, there will be <membership> tag, search for it. You will find membership and role manager under the <system.web> element. Under the membership providers section add the below code… <add name="SPFormAuthMembership" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" applicationName="FormAuthApplication" connectionStringName="FormAuthConnString" /> After adding memberhip element, see the snapshot of the web.config. Now you need to add role manager element to the web.config. Insider providers element under rolemanager, add the below code. <add name="SPFormAuthRoleManager" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" applicationName="FormAuthApplication" connectionStringName="FormAuthConnString" /> After adding, your role manager will look similar to the following. As a last step, you need to update the people picker wildcard element in web.config, so that the users from your membership provider are available for browsing in Central Administration. Search for PeoplePickerWildcards in the web.config, add the following inside the <PeoplePickerWildcards> tag. <add key="SPFormAuthMembership" value="%" /> After adding this element, your web.config will look like After completing these steps, you can browse the users available in the SQL server database from central administration website. Go to the site collection administrator’s page from central administration. Select the site collection you have created for form authentication. Click on the people picker icon, choose Forms Auth and click on the search icon, you will see the users listed from the SQL server database. Once you complete these steps, make sure the users are available for browsing from central administration website. If you are unable to find the users, there must be some errors in the configuration, check windows event logs to find related errors and fix them. Change the web.config for STS application Open the web.config for STS application in text editor. By default, STS web.config does not have system.Web or connectionstrings section. Just after the System.Webserver element, add the following code. <connectionStrings> <add name="FormAuthConnString" connectionString="Initial Catalog=aspnetdb_claim;data source=sp2010_db;Integrated Security=SSPI;" /> </connectionStrings> <system.web> <roleManager enabled="true" cacheRolesInCookie="false" cookieName=".ASPXROLES" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" cookieProtection="All" createPersistentCookie="false" maxCachedResults="25"> <providers> <add name="SPFormAuthRoleManager" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" applicationName="FormAuthApplication" connectionStringName="FormAuthConnString" /> </providers> </roleManager> <membership userIsOnlineTimeWindow="15" hashAlgorithmType=""> <providers> <add name="SPFormAuthMembership" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" applicationName="FormAuthApplication" connectionStringName="FormAuthConnString" /> </providers> </membership> </system.web> See the snapshot of the web.config after adding the required elements. After adding this, you should be able to login using the credentials from SQL server. Try assigning a user as primary/secondary administrator for your site collection from Central Administration and login to your site using form authentication. If you made everything correct, you should be able to login. This means you have successfully completed configuration of STS Configuration of Web Application for Form Authentication As a last step, you need to modify the web.config of the form authentication web application. Once you have done this, you should be able to grant permissions to users stored in the membership database. Open the Web.config of the web application you created for form authentication. You can find the web.config for the application under the path C:\inetpub\wwwroot\wss\VirtualDirectories\<port number> Basically you need to add connection string, membership provider, role manager and update the people picker wild card configuration. Add the connection string (same as the one you added to the web.config in Central Administration). See the screenshot after the connection string has added. Search for <membership> in the web.config, you will find this inside system.web element. There will be other providers already available there. You add your form authentication membership provider (similar to the one added to Central Administration web.config) to the provider element under membership. Find the snapshot of membership configuration as follows. Search for <roleManager> element in web.config, add the new provider name under providers section of the roleManager element. See the snapshot of web.config after new provider added. Now you need to configure the peoplepickerwildcard configuration in web.config. As I specified earlier, this is to make sure, you can locate the users by entering a part of their username. Add the following line under the <PeoplePickerWildcards> element in web.config. See the screenshot of the peoplePickerWildcards element after the element has been added. Now you have completed all the setup for form authentication. Navigate to the web application. From the site actions -> site settings -> go to peope and groups Click on new -> add users, it will popup the people picker dialog. Click on the icon, select Form Auth, enter a username in the search textbox, and click on search icon. See the screenshot of admin search when I tried searching the users If it displays the user, it means you are done with the configuration. If you add users to the form authentication database, the users will be able to access SharePoint portal as normal.

• Spritebatch drawing sprite with jagged borders

  - by Mutoh

  Alright, I've been on the making of a sprite class and a sprite sheet manager, but have come across this problem. Pretty much, the project is acting like so; for example: Let's take this .png image, with a transparent background. Note how it has alpha-transparent pixels around it in the lineart. Now, in the latter link's image, in the left (with CornflowerBlue background) it is shown the image drawn in another project (let's call it "Project1") with a simpler sprite class - there, it works. The right (with Purple background for differentiating) shows it drawn with a different class in "Project2" - where the problem manifests itself. This is the Sprite class of Project1: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.Graphics; namespace WindowsGame2 { class Sprite { Vector2 pos = new Vector2(0, 0); Texture2D image; Rectangle size; float scale = 1.0f; // --- public float X { get { return pos.X; } set { pos.X = value; } } public float Y { get { return pos.Y; } set { pos.Y = value; } } public float Width { get { return size.Width; } } public float Height { get { return size.Height; } } public float Scale { get { return scale; } set { if (value < 0) value = 0; scale = value; if (image != null) { size.Width = (int)(image.Width * scale); size.Height = (int)(image.Height * scale); } } } // --- public void Load(ContentManager Man, string filename) { image = Man.Load<Texture2D>(filename); size = new Rectangle( 0, 0, (int)(image.Width * scale), (int)(image.Height * scale) ); } public void Become(Texture2D frame) { image = frame; size = new Rectangle( 0, 0, (int)(image.Width * scale), (int)(image.Height * scale) ); } public void Draw(SpriteBatch Desenhista) { // Desenhista.Draw(image, pos, Color.White); Desenhista.Draw( image, pos, new Rectangle( 0, 0, image.Width, image.Height ), Color.White, 0.0f, Vector2.Zero, scale, SpriteEffects.None, 0 ); } } } And this is the code in Project2, a rewritten, pretty much, version of the previous class. In this one I added sprite sheet managing and, in particular, removed Load and Become, to allow for static resources and only actual Sprites to be instantiated. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.Graphics; namespace Mobby_s_Adventure { // Actually, I might desconsider this, and instead use static AnimationLocation[] and instanciated ID and Frame; // For determining the starting frame of an animation in a sheet and being able to iterate through // the Rectangles vector of the Sheet; class AnimationLocation { public int Location; public int FrameCount; // --- public AnimationLocation(int StartingRow, int StartingColumn, int SheetWidth, int NumberOfFrames) { Location = (StartingRow * SheetWidth) + StartingColumn; FrameCount = NumberOfFrames; } public AnimationLocation(int PositionInSheet, int NumberOfFrames) { Location = PositionInSheet; FrameCount = NumberOfFrames; } public static int CalculatePosition(int StartingRow, int StartingColumn, SheetManager Sheet) { return ((StartingRow * Sheet.Width) + StartingColumn); } } class Sprite { // The general stuff; protected SheetManager Sheet; protected Vector2 Position; public Vector2 Axis; protected Color _Tint; public float Angle; public float Scale; protected SpriteEffects _Effect; // --- // protected AnimationManager Animation; // For managing the animations; protected AnimationLocation[] Animation; public int AnimationID; protected int Frame; // --- // Properties for easy accessing of the position of the sprite; public float X { get { return Position.X; } set { Position.X = Axis.X + value; } } public float Y { get { return Position.Y; } set { Position.Y = Axis.Y + value; } } // --- // Properties for knowing the size of the sprite's frames public float Width { get { return Sheet.FrameWidth * Scale; } } public float Height { get { return Sheet.FrameHeight * Scale; } } // --- // Properties for more stuff; public Color Tint { set { _Tint = value; } } public SpriteEffects Effect { set { _Effect = value; } } public int FrameID { get { return Frame; } set { if (value >= (Animation[AnimationID].FrameCount)) value = 0; Frame = value; } } // --- // The only things that will be constantly modified will be AnimationID and FrameID, anything else only // occasionally; public Sprite(SheetManager SpriteSheet, AnimationLocation[] Animations, Vector2 Location, Nullable<Vector2> Origin = null) { // Assign the sprite's sprite sheet; // (Passed by reference! To allow STATIC sheets!) Sheet = SpriteSheet; // Define the animations that the sprite has available; // (Passed by reference! To allow STATIC animation boundaries!) Animation = Animations; // Defaulting some numerical values; Angle = 0.0f; Scale = 1.0f; _Tint = Color.White; _Effect = SpriteEffects.None; // If the user wants a default Axis, it is set in the middle of the frame; if (Origin != null) Axis = Origin.Value; else Axis = new Vector2( Sheet.FrameWidth / 2, Sheet.FrameHeight / 2 ); // Now that we have the axis, we can set the position with no worries; X = Location.X; Y = Location.Y; } // Simply put, draw the sprite with all its characteristics; public void Draw(SpriteBatch Drafter) { Drafter.Draw( Sheet.Texture, Position, Sheet.Rectangles[Animation[AnimationID].Location + FrameID], // Find the rectangle which frames the wanted image; _Tint, Angle, Axis, Scale, _Effect, 0.0f ); } } } And, in any case, this is the SheetManager class found in the previous code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.Graphics; namespace Mobby_s_Adventure { class SheetManager { protected Texture2D SpriteSheet; // For storing the sprite sheet; // Number of rows and frames in each row in the SpriteSheet; protected int NumberOfRows; protected int NumberOfColumns; // Size of a single frame; protected int _FrameWidth; protected int _FrameHeight; public Rectangle[] Rectangles; // For storing each frame; // --- public int Width { get { return NumberOfColumns; } } public int Height { get { return NumberOfRows; } } // --- public int FrameWidth { get { return _FrameWidth; } } public int FrameHeight { get { return _FrameHeight; } } // --- public Texture2D Texture { get { return SpriteSheet; } } // --- public SheetManager (Texture2D Texture, int Rows, int FramesInEachRow) { // Normal assigning SpriteSheet = Texture; NumberOfRows = Rows; NumberOfColumns = FramesInEachRow; _FrameHeight = Texture.Height / NumberOfRows; _FrameWidth = Texture.Width / NumberOfColumns; // Framing everything Rectangles = new Rectangle[NumberOfRows * NumberOfColumns]; int ID = 0; for (int i = 0; i < NumberOfRows; i++) { for (int j = 0; j < NumberOfColumns; j++) { Rectangles[ID] = new Rectangle ( _FrameWidth * j, _FrameHeight * i, _FrameWidth, _FrameHeight ); ID++; } } } public SheetManager (Texture2D Texture, int NumberOfFrames): this(Texture, 1, NumberOfFrames) { } } } For even more comprehending, if needed, here is how the main code looks like (it's just messing with the class' capacities, nothing actually; the result is a disembodied feet walking in place animation on the top-left of the screen and a static axe nearby): using System; using System.Collections.Generic; using System.Linq; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Audio; using Microsoft.Xna.Framework.Content; using Microsoft.Xna.Framework.GamerServices; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; using Microsoft.Xna.Framework.Media; using System.Threading; namespace Mobby_s_Adventure { /// <summary> /// This is the main type for your game /// </summary> public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; static List<Sprite> ToDraw; static Texture2D AxeSheet; static Texture2D FeetSheet; static SheetManager Axe; static Sprite Jojora; static AnimationLocation[] Hack = new AnimationLocation[1]; static SheetManager Feet; static Sprite Mutoh; static AnimationLocation[] FeetAnimations = new AnimationLocation[2]; public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; this.TargetElapsedTime = TimeSpan.FromMilliseconds(100); this.IsFixedTimeStep = true; } /// <summary> /// Allows the game to perform any initialization it needs to before starting to run. /// This is where it can query for any required services and load any non-graphic /// related content.

One thing that I have noticed and could aid is that, if inserted the equivalent of this code spriteBatch.Draw( Content.Load<Texture2D>("Image Location"), new Rectangle(X, Y, images width, height), Color.White ); in Project2's Draw(GameTime) of the main loop, it works. EDIT Ok, even if the matter remains unsolved, I have made some more progress! As you see, I managed to get the two kinds of rendering in the same project (the aforementioned Project2, with the more complex Sprite class). This was achieved by adding the following code to Draw(GameTime): protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.Purple); // Drawing logic spriteBatch.Begin(); foreach (Sprite Element in ToDraw) { Element.Draw(spriteBatch); } // Starting here spriteBatch.Draw( Axe.Texture, new Vector2(65, 100), new Rectangle ( 0, 0, Axe.FrameWidth, Axe.FrameHeight ), Color.White, 0.0f, new Vector2(0, 0), 1.0f, SpriteEffects.None, 0.0f ); // Ending here spriteBatch.End(); base.Draw(gameTime); } (Supposing that Axe is the SheetManager containing the texture, sorry if the "jargons" of my code confuse you :s) Thus, I have noticed that the problem is within the Sprite class. But I only get more clueless, because even after modifying its Draw function to this: public void Draw(SpriteBatch Drafter) { /*Drafter.Draw( Sheet.Texture, Position, Sheet.Rectangles[Animation[AnimationID].Location + FrameID], // Find the rectangle which frames the wanted image; _Tint, Angle, Axis, Scale, _Effect, 0.0f );*/ Drafter.Draw( Sheet.Texture, Position, new Rectangle( 0, 0, Sheet.FrameWidth, Sheet.FrameHeight ), Color.White, 0.0f, Vector2.Zero, Scale, SpriteEffects.None, 0 ); } to make it as simple as the patch of code that works, it still draws the sprite jaggedly!

• WD MBWE II (White Strip Light) 2TB - unable to access data

  - by user210477

  I have a WD MBWE II (White Strip Light) 2TB - (WD20000H2NC-00) Was working fine until a few days ago. I guess there was a power failure and after that I am unable to access the 'Public' or the 'Download' folder anymore. I have been searching for answers everywhere but came up empty handed. Web GUI still works, SSH works. I hooked up both the drives on my PC and UFS Explorer sees the drive. But so far I am unable to retrieve any of my data. I do not remember what RAID setting I used when I first got the drive. I can see from GUI that it is set as "Stripe". The drive contains 10 years of family pictures which I really do not want to loose. Sadly and stupidly, I didn't even keep a backup of this drive. Can somebody please help or point me in the right direction. Thank you in advance for your help. Disk Utility on Ubuntu reports 1405 bad sectors on one drive. How can I retrieve my data? Please help.

• VSTO Word ContentControls, Y U No have Name property?

  - by System.Cats.Lol

  When you add a VSTO (not Word native) content control, you specify the name: controls.AddContentControl(wordRange, "foo", wdType); Where controls is the VSTO (extended) Document.Controls collection. You can later look up the control by name: ContentControl myContentControl = controls["foo"]; So why in the world is there no Name property for ContentControl? (or ContentControlBase, or any of the other derivatives). I'm implementing a wrapper class for the Document.Controls property that lets you add or iterate the content controls. When iterating the underlying Document.Controls, there's no way to look up the name of each control. (We need it to return an instance of our ContentControl wrapper). So currently I'm doing this in our ContentControls wrapper class: public IEnumerator<IContentControl> GetEnumerator() { System.Collections.IEnumerator en = this.wordControls.GetEnumerator(); while (en.MoveNext()) { // VSTO Document.Controls includes all managed controls, not just // VSTO ContentControls; return only those. if (en.Current is Microsoft.Office.Tools.Word.ContentControl) { // The control's name isn't stored with the control, only when it was added, // so use a placeholder name for the wrapper. yield return new ContentControl("Unknown", (Microsoft.Office.Tools.Word.ContentControl)en.Current); } } } I'd prefer to not have to resort to keeping a map of names-to-wrapper-objects in our ContentControls object. Can anyone tell me how to get the control's name (the name parameter that was passed to Controls.Add()?

• How to Reduce the Size of Your WinSXS Folder on Windows 7 or 8

  - by Chris Hoffman

  The WinSXS folder at C:\Windows\WinSXS is massive and continues to grow the longer you have Windows installed. This folder builds up unnecessary files over time, such as old versions of system components. This folder also contains files for uninstalled, disabled Windows components. Even if you don’t have a Windows component installed, it will be present in your WinSXS folder, taking up space. Why the WinSXS Folder Gets to Big The WinSXS folder contains all Windows system components. In fact, component files elsewhere in Windows are just links to files contained in the WinSXS folder. The WinSXS folder contains every operating system file. When Windows installs updates, it drops the new Windows component in the WinSXS folder and keeps the old component in the WinSXS folder. This means that every Windows Update you install increases the size of your WinSXS folder. This allows you to uninstall operating system updates from the Control Panel, which can be useful in the case of a buggy update — but it’s a feature that’s rarely used. Windows 7 dealt with this by including a feature that allows Windows to clean up old Windows update files after you install a new Windows service pack. The idea was that the system could be cleaned up regularly along with service packs. However, Windows 7 only saw one service pack — Service Pack 1 — released in 2010. Microsoft has no intention of launching another. This means that, for more than three years, Windows update uninstallation files have been building up on Windows 7 systems and couldn’t be easily removed. Clean Up Update Files To fix this problem, Microsoft recently backported a feature from Windows 8 to Windows 7. They did this without much fanfare — it was rolled out in a typical minor operating system update, the kind that don’t generally add new features. To clean up such update files, open the Disk Cleanup wizard (tap the Windows key, type “disk cleanup” into the Start menu, and press Enter). Click the Clean up System Files button, enable the Windows Update Cleanup option and click OK. If you’ve been using your Windows 7 system for a few years, you’ll likely be able to free several gigabytes of space. The next time you reboot after doing this, Windows will take a few minutes to clean up system files before you can log in and use your desktop. If you don’t see this feature in the Disk Cleanup window, you’re likely behind on your updates — install the latest updates from Windows Update. Windows 8 and 8.1 include built-in features that do this automatically. In fact, there’s a StartComponentCleanup scheduled task included with Windows that will automatically run in the background, cleaning up components 30 days after you’ve installed them. This 30-day period gives you time to uninstall an update if it causes problems. If you’d like to manually clean up updates, you can also use the Windows Update Cleanup option in the Disk Usage window, just as you can on Windows 7. (To open it, tap the Windows key, type “disk cleanup” to perform a search, and click the “Free up disk space by removing unnecessary files” shortcut that appears.) Windows 8.1 gives you more options, allowing you to forcibly remove all previous versions of uninstalled components, even ones that haven’t been around for more than 30 days. These commands must be run in an elevated Command Prompt — in other words, start the Command Prompt window as Administrator. For example, the following command will uninstall all previous versions of components without the scheduled task’s 30-day grace period: DISM.exe /online /Cleanup-Image /StartComponentCleanup The following command will remove files needed for uninstallation of service packs. You won’t be able to uninstall any currently installed service packs after running this command: DISM.exe /online /Cleanup-Image /SPSuperseded The following command will remove all old versions of every component. You won’t be able to uninstall any currently installed service packs or updates after this completes: DISM.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase Remove Features on Demand Modern versions of Windows allow you to enable or disable Windows features on demand. You’ll find a list of these features in the Windows Features window you can access from the Control Panel. Even features you don’t have installed — that is, the features you see unchecked in this window — are stored on your hard drive in your WinSXS folder. If you choose to install them, they’ll be made available from your WinSXS folder. This means you won’t have to download anything or provide Windows installation media to install these features. However, these features take up space. While this shouldn’t matter on typical computers, users with extremely low amounts of storage or Windows server administrators who want to slim their Windows installs down to the smallest possible set of system files may want to get these files off their hard drives. For this reason, Windows 8 added a new option that allows you to remove these uninstalled components from the WinSXS folder entirely, freeing up space. If you choose to install the removed components later, Windows will prompt you to download the component files from Microsoft. To do this, open a Command Prompt window as Administrator. Use the following command to see the features available to you: DISM.exe /Online /English /Get-Features /Format:Table You’ll see a table of feature names and their states. To remove a feature from your system, you’d use the following command, replacing NAME with the name of the feature you want to remove. You can get the feature name you need from the table above. DISM.exe /Online /Disable-Feature /featurename:NAME /Remove If you run the /GetFeatures command again, you’ll now see that the feature has a status of “Disabled with Payload Removed” instead of just “Disabled.” That’s how you know it’s not taking up space on your computer’s hard drive. If you’re trying to slim down a Windows system as much as possible, be sure to check out our lists of ways to free up disk space on Windows and reduce the space used by system files.

• Writing the tests for FluentPath

  - by Bertrand Le Roy

  Writing the tests for FluentPath is a challenge. The library is a wrapper around a legacy API (System.IO) that wasn’t designed to be easily testable. If it were more testable, the sensible testing methodology would be to tell System.IO to act against a mock file system, which would enable me to verify that my code is doing the expected file system operations without having to manipulate the actual, physical file system: what we are testing here is FluentPath, not System.IO. Unfortunately, that is not an option as nothing in System.IO enables us to plug a mock file system in. As a consequence, we are left with few options. A few people have suggested me to abstract my calls to System.IO away so that I could tell FluentPath – not System.IO – to use a mock instead of the real thing. That in turn is getting a little silly: FluentPath already is a thin abstraction around System.IO, so layering another abstraction between them would double the test surface while bringing little or no value. I would have to test that new abstraction layer, and that would bring us back to square one. Unless I’m missing something, the only option I have here is to bite the bullet and test against the real file system. Of course, the tests that do that can hardly be called unit tests. They are more integration tests as they don’t only test bits of my code. They really test the successful integration of my code with the underlying System.IO. In order to write such tests, the techniques of BDD work particularly well as they enable you to express scenarios in natural language, from which test code is generated. Integration tests are being better expressed as scenarios orchestrating a few basic behaviors, so this is a nice fit. The Orchard team has been successfully using SpecFlow for integration tests for a while and I thought it was pretty cool so that’s what I decided to use. Consider for example the following scenario: Scenario: Change extension Given a clean test directory When I change the extension of bar\notes.txt to foo Then bar\notes.txt should not exist And bar\notes.foo should exist This is human readable and tells you everything you need to know about what you’re testing, but it is also executable code. What happens when SpecFlow compiles this scenario is that it executes a bunch of regular expressions that identify the known Given (set-up phases), When (actions) and Then (result assertions) to identify the code to run, which is then translated into calls into the appropriate methods. Nothing magical. Here is the code generated by SpecFlow: [NUnit.Framework.TestAttribute()] [NUnit.Framework.DescriptionAttribute("Change extension")] public virtual void ChangeExtension() { TechTalk.SpecFlow.ScenarioInfo scenarioInfo = new TechTalk.SpecFlow.ScenarioInfo("Change extension", ((string[])(null))); #line 6 this.ScenarioSetup(scenarioInfo); #line 7 testRunner.Given("a clean test directory"); #line 8 testRunner.When("I change the extension of " + "bar\\notes.txt to foo"); #line 9 testRunner.Then("bar\\notes.txt should not exist"); #line 10 testRunner.And("bar\\notes.foo should exist"); #line hidden testRunner.CollectScenarioErrors();} The #line directives are there to give clues to the debugger, because yes, you can put breakpoints into a scenario: The way you usually write tests with SpecFlow is that you write the scenario first, let it fail, then write the translation of your Given, When and Then into code if they don’t already exist, which results in running but failing tests, and then you write the code to make your tests pass (you implement the scenario). In the case of FluentPath, I built a simple Given method that builds a simple file hierarchy in a temporary directory that all scenarios are going to work with: [Given("a clean test directory")] public void GivenACleanDirectory() { _path = new Path(SystemIO.Path.GetTempPath()) .CreateSubDirectory("FluentPathSpecs") .MakeCurrent(); _path.GetFileSystemEntries() .Delete(true); _path.CreateFile("foo.txt", "This is a text file named foo."); var bar = _path.CreateSubDirectory("bar"); bar.CreateFile("baz.txt", "bar baz") .SetLastWriteTime(DateTime.Now.AddSeconds(-2)); bar.CreateFile("notes.txt", "This is a text file containing notes."); var barbar = bar.CreateSubDirectory("bar"); barbar.CreateFile("deep.txt", "Deep thoughts"); var sub = _path.CreateSubDirectory("sub"); sub.CreateSubDirectory("subsub"); sub.CreateFile("baz.txt", "sub baz") .SetLastWriteTime(DateTime.Now); sub.CreateFile("binary.bin", new byte[] {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0xFF}); } Then, to implement the scenario that you can read above, I had to write the following When: [When("I change the extension of (.*) to (.*)")] public void WhenIChangeTheExtension( string path, string newExtension) { var oldPath = Path.Current.Combine(path.Split('\\')); oldPath.Move(p => p.ChangeExtension(newExtension)); } As you can see, the When attribute is specifying the regular expression that will enable the SpecFlow engine to recognize what When method to call and also how to map its parameters. For our scenario, “bar\notes.txt” will get mapped to the path parameter, and “foo” to the newExtension parameter. And of course, the code that verifies the assumptions of the scenario: [Then("(.*) should exist")] public void ThenEntryShouldExist(string path) { Assert.IsTrue(_path.Combine(path.Split('\\')).Exists); } [Then("(.*) should not exist")] public void ThenEntryShouldNotExist(string path) { Assert.IsFalse(_path.Combine(path.Split('\\')).Exists); } These steps should be written with reusability in mind. They are building blocks for your scenarios, not implementation of a specific scenario. Think small and fine-grained. In the case of the above steps, I could reuse each of those steps in other scenarios. Those tests are easy to write and easier to read, which means that they also constitute a form of documentation. Oh, and SpecFlow is just one way to do this. Rob wrote a long time ago about this sort of thing (but using a different framework) and I highly recommend this post if I somehow managed to pique your interest: http://blog.wekeroad.com/blog/make-bdd-your-bff-2/ And this screencast (Rob always makes excellent screencasts): http://blog.wekeroad.com/mvc-storefront/kona-3/ (click the “Download it here” link)

• Running Solaris 11 as a control domain on a T2000

  - by jsavit

  There is increased adoption of Oracle Solaris 11, and many customers are deploying it on systems that previously ran Solaris 10. That includes older T1-processor based systems like T1000 and T2000. Even though they are old (from 2005) and don't have the performance of current SPARC servers, they are still functional, stable servers that customers continue to operate. One reason to install Solaris 11 on them is that older machines are attractive for testing OS upgrades before updating current, production systems. Normally this does not present a challenge, because Solaris 11 runs on any T-series or M-series SPARC server. One scenario adds a complication: running Solaris 11 in a control domain on a T1000 or T2000 hosting logical domains. Solaris 11 pre-installed Oracle VM Server for SPARC incompatible with T1 Unlike Solaris 10, Solaris 11 comes with Oracle VM Server for SPARC preinstalled. The ldomsmanager package contains the logical domains manager for Oracle VM Server for SPARC 2.2, which requires a SPARC T2, T2+, T3, or T4 server. It does not work with T1-processor systems, which are only supported by LDoms Manager 1.2 and earlier. The following screenshot shows what happens (bold font) if you try to use Oracle VM Server for SPARC 2.x commands in a Solaris 11 control domain. The commands were issued in a control domain on a T2000 that previously ran Solaris 10. We also display the version of the logical domains manager installed in Solaris 11: root@t2000 psrinfo -vp The physical processor has 4 virtual processors (0-3) UltraSPARC-T1 (chipid 0, clock 1200 MHz) # prtconf|grep T SUNW,Sun-Fire-T200 # ldm -V Failed to connect to logical domain manager: Connection refused # pkg info ldomsmanager Name: system/ldoms/ldomsmanager Summary: Logical Domains Manager Description: LDoms Manager - Virtualization for SPARC T-Series Category: System/Virtualization State: Installed Publisher: solaris Version: 2.2.0.0 Build Release: 5.11 Branch: 0.175.0.8.0.3.0 Packaging Date: May 25, 2012 10:20:48 PM Size: 2.86 MB FMRI: pkg://solaris/system/ldoms/[email protected],5.11-0.175.0.8.0.3.0:20120525T222048Z The 2.2 version of the logical domains manager will have to be removed, and 1.2 installed, in order to use this as a control domain. Preparing to change - create a new boot environment Before doing anything else, lets create a new boot environment: # beadm list BE Active Mountpoint Space Policy Created -- ------ ---------- ----- ------ ------- solaris NR / 2.14G static 2012-09-25 10:32 # beadm create solaris-1 # beadm activate solaris-1 # beadm list BE Active Mountpoint Space Policy Created -- ------ ---------- ----- ------ ------- solaris N / 4.82M static 2012-09-25 10:32 solaris-1 R - 2.14G static 2012-09-29 11:40 # init 0 Normally an init 6 to reboot would have been sufficient, but in the next step I reset the system anyway in order to put the system in factory default mode for a "clean" domain configuration. Preparing to change - reset to factory default There was a leftover domain configuration on the T2000, so I reset it to the factory install state. Since the ldm command is't working yet, it can't be done from the control domain, so I did it by logging onto to the service processor: $ ssh -X admin@t2000-sc Copyright (c) 2010, Oracle and/or its affiliates.

Remove ldomsmanager 2.2 and install the 1.2 version The Solaris 11 pkg command is now used to remove the 2.2 version that shipped with Solaris 11: # pkg uninstall ldomsmanager Packages to remove: 1 Create boot environment: No Create backup boot environment: No Services to change: 2 PHASE ACTIONS Removal Phase 130/130 PHASE ITEMS Package State Update Phase 1/1 Package Cache Update Phase 1/1 Image State Update Phase 2/2 Finally, LDoms 1.2 installed via its install script, the same way it was done years ago: # unzip LDoms-1_2-Integration-10.zip # cd LDoms-1_2-Integration-10/Install/ # ./install-ldm Welcome to the LDoms installer. You are about to install the Logical Domains Manager package that will enable you to create, destroy and control other domains on your system. Given the capabilities of the LDoms domain manager, you can now change the security configuration of this Solaris instance using the Solaris Security Toolkit. ... ... normal install messages omitted ... The Solaris Security Toolkit applies to Solaris 10, and cannot be used in Solaris 11 (in which several things hardened by the Toolkit are already hardened by default), so answer b in the choice below: You are about to install the Logical Domains Manager package that will enable you to create, destroy and control other domains on your system. Given the capabilities of the LDoms domain manager, you can now change the security configuration of this Solaris instance using the Solaris Security Toolkit. Select a security profile from this list: a) Hardened Solaris configuration for LDoms (recommended) b) Standard Solaris configuration c) Your custom-defined Solaris security configuration profile Enter a, b, or c [a]: b ... other install messages omitted for brevity... After install I ensure that the necessary services are enabled, and verify the version of the installed LDoms Manager: # svcs ldmd STATE STIME FMRI online 22:00:36 svc:/ldoms/ldmd:default # svcs vntsd STATE STIME FMRI disabled Aug_19 svc:/ldoms/vntsd:default # ldm -V Logical Domain Manager (v 1.2-debug) Hypervisor control protocol v 1.3 Using Hypervisor MD v 1.1 System PROM: Hypervisor v. 1.7.3. @(#)Hypervisor 1.7.3.c 2010/07/09 15:14\015 OpenBoot v. 4.30.4. @(#)OBP 4.30.4.b 2010/07/09 13:48 Set up control domain and domain services At this point we have a functioning LDoms 1.2 environment that can be configured in the usual fashion. One difference is that LDoms 1.2 behavior had 'delayed configuration mode (as expected) during initial configuration before rebooting the control domain. Another minor difference with a Solaris 11 control domain is that you define virtual switches using the 'vanity name' of the network interface, rather than the hardware driver name as in Solaris 10. # ldm list ------------------------------------------------------------------------------ Notice: the LDom Manager is running in configuration mode. Configuration and resource information is displayed for the configuration under construction; not the current active configuration.

After reboot, we are ready to install guest domains. Summary - new wine in old bottles This example shows that (new) Solaris 11 can be installed on (old) T2000 servers and used as a control domain. The main activity is to remove the preinstalled Oracle VM Server for 2.2 and install Logical Domains 1.2 - the last version of LDoms to support T1-processor systems. I tested Solaris 10 and Solaris 11 guest domains running on this server and they worked without any surprises. This is a viable way to get further into Solaris 11 adoption, even on older T-series equipment.

• How to solve SocketException: Permission denied: connect

  - by luxinxian

  I recently encountered a problem that is giving me a headache and I need help ... The System consists of two subsystems, called A and B, each running on a standalone Tomcat instance and currently running on the same machine. A invokes B's service via Spring httpInvoker (i.e. over HTTP). B system also invokes the other system's services via HTTP. Symptoms: the system starts to run and appears to work normally for around 10-15 days; the system will run for a period of time after an exception: org.springframework.remoting.RemoteAccessException: Could not access HTTP invoker remote service at [http://xxx.xxx.xxx.xxx/remoting/call]; The nested exception is java. net.SocketException: **Permission denied: connect** when the exception occurs, the system continues. This happens always, not only occasionally. (It looks like some resources are exhausted, but CPU rate < 5%, memory < 15%, network < 5%). when the system call between A and B fails, the B system call over HTTP to an external service also failed, with the same exception. Restarting both Tomcat services makes the whole system work properly. So repeatedly following steps 1 - 5, I have not found the root reason. Environment: windows 2008 R2 tomcat7.0.42 x86_64 oralce-jdk-1.7.0_40 Any ideas?

• Buffer Overflow errors when reading ConfigDelay and Manufacturer info from registry

  - by peter

  Hi All, This is a strange driver error which doesn't make a lot of sense to me. I am running an application developed in C# .NET which our company develops. I was monitoring the application using process monitor and noticed that it accesses the registry a lot. The output on Process Monitor looks like this, Operation Result Path RegQueryValue Success HKLM\System\CurrentControlSet\Enum\SWMUXBUS\SW_MODEM\7&6c4af30&0&5&0004\Driver RegQueryValue Success HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\Properties RegQueryValue Success HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\Default RegQueryValue Success HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\InactivityScale RegQueryValue Name Not Found HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\PowerDelay RegQueryValue Name Not Found HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\ConfigDelay RegQueryValue Buffer Overflow HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\Manufacturer RegQueryValue Buffer Overflow HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\Model RegQueryValue Name Not Found HKLM\System\CurrentControlSet\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\Version The app is reading this stuff every 5 seconds from the registry, so I would ask a few questions, 1) What is this stuff 2) Why is the app reading this stuff 3) Why is it saying 'Buffer Overflow' 4) Could this cause performance problems for my app?

• Waterfall Model (SDLC) vs. Prototyping Model

  The characters in the fable of the Tortoise and the Hare can easily be used to demonstrate the similarities and differences between the Waterfall and Prototyping software development models. This children fable is about a race between a consistently slow moving but steadfast turtle and an extremely fast but unreliable rabbit. After closely comparing each character’s attributes in correlation with both software development models, a trend seems to appear in that the Waterfall closely resembles the Tortoise in that Waterfall Model is typically a slow moving process that is broken up in to multiple sequential steps that must be executed in a standard linear pattern. The Tortoise can be quoted several times in the story saying “Slow and steady wins the race.” This is the perfect mantra for the Waterfall Model in that this model is seen as a cumbersome and slow moving. Waterfall Model Phases Requirement Analysis & Definition This phase focuses on defining requirements for a project that is to be developed and determining if the project is even feasible. Requirements are collected by analyzing existing systems and functionality in correlation with the needs of the business and the desires of the end users. The desired output for this phase is a list of specific requirements from the business that are to be designed and implemented in the subsequent steps. In addition this phase is used to determine if any value will be gained by completing the project. System Design This phase focuses primarily on the actual architectural design of a system, and how it will interact within itself and with other existing applications. Projects at this level should be viewed at a high level so that actual implementation details are decided in the implementation phase. However major environmental decision like hardware and platform decision are typically decided in this phase. Furthermore the basic goal of this phase is to design an application at the system level in those classes, interfaces, and interactions are defined. Additionally decisions about scalability, distribution and reliability should also be considered for all decisions. The desired output for this phase is a functional  design document that states all of the architectural decisions that have been made in regards to the project as well as a diagrams like a sequence and class diagrams. Software Design This phase focuses primarily on the refining of the decisions found in the functional design document. Classes and interfaces are further broken down in to logical modules based on the interfaces and interactions previously indicated. The output of this phase is a formal design document. Implementation / Coding This phase focuses primarily on implementing the previously defined modules in to units of code. These units are developed independently are intergraded as the system is put together as part of a whole system. Software Integration & Verification This phase primarily focuses on testing each of the units of code developed as well as testing the system as a whole. There are basic types of testing at this phase and they include: Unit Test and Integration Test. Unit Test are built to test the functionality of a code unit to ensure that it preforms its desired task. Integration testing test the system as a whole because it focuses on results of combining specific units of code and validating it against expected results. The output of this phase is a test plan that includes test with expected results and actual results. System Verification This phase primarily focuses on testing the system as a whole in regards to the list of project requirements and desired operating environment. Operation & Maintenance his phase primarily focuses on handing off the competed project over to the customer so that they can verify that all of their requirements have been met based on their original requirements. This phase will also validate the correctness of their requirements and if any changed need to be made. In addition, any problems not resolved in the previous phase will be handled in this section. The Waterfall Model’s linear and sequential methodology does offer a project certain advantages and disadvantages. Advantages of the Waterfall Model Simplistic to implement and execute for projects and/or company wide Limited demand on resources Large emphasis on documentation Disadvantages of the Waterfall Model Completed phases cannot be revisited regardless if issues arise within a project Accurate requirement are never gather prior to the completion of the requirement phase due to the lack of clarification in regards to client’s desires. Small changes or errors that arise in applications may cause additional problems The client cannot change any requirements once the requirements phase has been completed leaving them no options for changes as they see their requirements changes as the customers desires change. Excess documentation Phases are cumbersome and slow moving Learn more about the Major Process in the Sofware Development Life Cycle and Waterfall Model. Conversely, the Hare shares similar traits with the prototyping software development model in that ideas are rapidly converted to basic working examples and subsequent changes are made to quickly align the project with customers desires as they are formulated and as software strays from the customers vision. The basic concept of prototyping is to eliminate the use of well-defined project requirements. Projects are allowed to grow as the customer needs and request grow. Projects are initially designed according to basic requirements and are refined as requirement become more refined. This process allows customer to feel their way around the application to ensure that they are developing exactly what they want in the application This model also works well for determining the feasibility of certain approaches in regards to an application. Prototypes allow for quickly developing examples of implementing specific functionality based on certain techniques. Advantages of Prototyping Active participation from users and customers Allows customers to change their mind in specifying requirements Customers get a better understanding of the system as it is developed Earlier bug/error detection Promotes communication with customers Prototype could be used as final production Reduced time needed to develop applications compared to the Waterfall method Disadvantages of Prototyping Promotes constantly redefining project requirements that cause major system rewrites Potential for increased complexity of a system as scope of the system expands Customer could believe the prototype as the working version. Implementation compromises could increase the complexity when applying updates and or application fixes When companies trying to decide between the Waterfall model and Prototype model they need to evaluate the benefits and disadvantages for both models. Typically smaller companies or projects that have major time constraints typically head for more of a Prototype model approach because it can reduce the time needed to complete the project because there is more of a focus on building a project and less on defining requirements and scope prior to the start of a project. On the other hand, Companies with well-defined requirements and time allowed to generate proper documentation should steer towards more of a waterfall model because they are in a position to obtain clarified requirements and have to design and optimal solution prior to the start of coding on a project.

• 2011 i7 Macbook Pro unable to boot from any Windows CD?

  - by Craig Otis

  I'm encountering issues installing Windows alongside my Lion install. I'm attempting to install from the internal SuperDrive, after using Boot Camp to partition what was a single, HFS+ volume. When holding down Option at boot, the CD appears in the startup list, but upon selecting it, I get a gray screen for 5 minutes, then a flashing white folder. I tried installing rEFIt and using this to boot the CD, but I receive an error about "Not Found" being returned from the "LocateDevicePath", and a mention of the firmware not supporting booting using legacy methods. In the Console, when opening the StartupDisk preference pane (which never presents the CD as a selectable option), I see: 11/25/11 4:39:31.159 PM System Preferences: isCDROM: 0 isDVDROM:1 11/25/11 4:39:31.159 PM System Preferences: mountable disk appeared: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.214 PM System Preferences: - So far so good, passing disk to System Searcher. 11/25/11 4:39:33.218 PM System Preferences: OSXCheck: No boot.efi in System Folder or volume root. 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD 11/25/11 4:39:33.220 PM System Preferences: WinCheck: Not a valid windows filesystem: /Volumes/GRMCPRFRER_EN_DVD I'm at a loss here. I've done my research, but it sounds like most of the rEFIt errors of this nature are caused by installing from a thumbdrive, or an external drive. I'm using the internal SuperDrive. Also, I've tried this with two different disks: A Windows XP SP2 CD A Windows 7 x86 DVD Both are disks I've had around for years, and I've used them reliably in the past. The system is an early 2011 15" Macbook Pro, all firmware updates installed.

• Kickstarting an Ubuntu Server 10.04 installation (DHCP fails)

  - by William

  I'm trying to automate the network installation of Ubuntu 10.04 LTS with an anaconda kickstart and everything seems to running except for the initial DHCP autoconfiguration. The installer attempts to configure the install via DHCP but fails on its first attempt. This brings me to a prompt where I can retry DHCP and it seems to always work on the second attempt. My issue is that this is not really automated if I have to hit retry for DHCP. Is there something I can add to the kickstart file so that it will automatically retry or better yet not fail the first time? Thanks.

• How To Quickly Reboot Directly from Windows 7 to XP, Vista, or Ubuntu

  - by The Geek

  One of the biggest annoyances with a dual-boot system is having to wait for your PC to reboot to select the operating system you want to switch to, but there’s a simple piece of software that can make this process easier. This guest article was written by Ryan Dozier from the Doztech tech blog. With a small piece of software called iReboot we can skip the above step all together and instantly reboot into the operating system we want right from Windows. Their description says: “Instead of pressing restart, waiting for Windows to shut down, waiting for your BIOS to post, then selecting the operating system you want to boot into (within the bootloader time-limit!); you just select that entry from iReboot and let it do the rest!” Don’t worry about iReboot reconfiguring  your bootloader or any dual boot configuration you have. iReboot will only boot the selected operating system once and go back to your default settings. Using iReboot iReboot is quick and easy to install. Just download it, link below, run through the setup and select the default configuration. iReboot will automatically figure out what operating systems you have installed and appear in the taskbar. Go over to the taskbar and right click on the iReboot icon and select which operating system you want to reboot into. This method will add a check mark on the operating system you want to boot into. On your next reboot the system will automatically load your choice and skip the Windows Boot Manager. If you want to reboot automatically just select “Reboot on Selection” in the iReboot menu.   To be even more productive, you can install iReboot into each Windows operating system to quickly access the others with a few simple clicks.   iReboot does not work in Linux so you will have to reboot manually. Then wait for the Windows Boot Manager to load and select your operating system.   Conclusion iReboot works on  Windows XP, Windows Vista,  and Windows 7 as well as 64 bit versions of these operating systems. Unfortunately iReboot is only available for Windows but you can still use its functionality in Windows to quickly boot up your Linux machine. A simple reboot in Linux will take you back to Windows Boot Manager. Download iReboot from neosmart.net Editor’s note: We’ve not personally tested this software over at How-To Geek, but Neosmart, the author of the software, generally makes quality stuff. Still, you might want to test it out on a test machine first. If you’ve got any experience with this software, please be sure to let your fellow readers know in the comments.

• bluez 5.19 PS4 controller

  - by Athanase

  I currently have a problem when pairing my computer with a PS4 remote. On my Ubuntu 14.04 I removed everything related with bluez and bluetooth, and I built and installed bluez 5.19. Here are some useful command outputs: jean@system ~ hcitool hcitool - HCI Tool ver 5.19 jean@system ~ hcitool dev Devices: hci0 00:15:83:4C:0C:BB jean@system ~ bluetoothctl [bluetooth]# version Version 5.19 jean@system ~ bluetoothctl [NEW] Controller 00:15:83:4C:0C:BB BlueZ [default] jean@system ~ lsusb Bus 003 Device 012: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) So here is what happens. When I try to hard pair the controller with the computer, by holding the share and ps button for a while, everything works as expected and the pairing is done properly. After a hard pairing if I try the pairing by pressing the ps button only, nothings happen. In order to go it, I first power up the bluetooth dongle: jean@system ~ sudo hciconfig hciX up and then I run the bluetooh deamon bluetoothd: jean@system /usr/libexec/bluetooth ~ ./bluetoothd -d -n

• Can't boot in Ubuntu after windows upgrade

  - by VanceAnce

  After my lastest update for Ubuntu and Windows XP, I got a Grub error on booting the next day. ls lists the following (without () ): sd0 sd1, msdos sd2 sd5 sd6 When I tried to get into one with (sd0,xy)/ it doesn't detect system or unknown file system error. I tried to boot to a live session with a Knoppix live CD and found out that all data exists. I also tried to recover with TestDisk and it finds all systems. Here is the test disk result: Start End Size in sectors 1 * HPFS - NTFS 0 1 1 7079 254 63 113740137 2 E extended LBA 7080 0 1 12161 254 63 81642330 5 L HPFS - NTFS 7080 1 1 10266 254 63 51199092 [Schule] X extended 12031 30 1 12161 254 63 2102625 6 L Linux Swap 12031 31 33 12161 254 63 2102530 I've 1 winxp-home, 1x Ubuntu (ext3+swap) and 1 winxp prof and then I wrote on mbr with TestDisk but I always get the same errors with Grub.

• Process Is The New App by Leon Smiers

  - by JuergenKress

  Process-on-the-Fly #2 - Process is the New App The next generation of business process management and business rules management tools is so powerful that it actually can be seen as the successor to custom-built applications. Being able to define detailed process, flows, decision trees and business helps on both the business and IT side to create powerful, differentiating solutions that would have required extensive custom coding in the past. Now much of the definition can be done ‘on the fly,’ using visual models and (semi) natural language in the nearest proximity to the business. Over the years, ERP systems have been customized to enter organization-specific functionality into the ERP application. This leads to better support for the business, but at the same time involves higher costs for maintenance, high dependency on the personnel involved in this customization, long timelines to deliver change to the system and increased risk involved in upgrading the ERP system. However, the best of both worlds can be created by bringing back the functionality to out-of-the-box usage of the ERP system and at the same time introducing change and flexibility by means of externalized 'Process Apps' in direct connection with the ERP system. The ERP system (or legacy bespoke system, for that matter) is used as originally intended and designed, resulting in more predictable behavior of the system related to usage and performance, and clearly can be maintained in a more standardized and cost-effective way. The Prrocess App externalizes the needed functionality into a highly customizable application outside the ERP for which it is supported by rules engines, task inboxes and can be delivered to different channels. The reasons for needing Process Apps may include the following: The ERP system just doesn't deliver this functionality in a specific industry; the volatility of changing certain functionality is high; or an umbrella type of functionality across (ERP) silos is needed. An example of bringing all this together is around the hiring process for a new employee at a university. Oracle PeopleSoft HCM could be used as the HR system to store all employee details. In the hiring process, an authorization scheme is involved for getting the approval to create a contract for the employee-to-be. In the university world, this authorization scheme is complex and involves faculties/colleges (with different organizational structures) and cross-faculty organizational structures. Including such an authorization scheme into PeopleSoft would require a lot of customization. By adding a handle inside PeopleSoft towards an externalized authorization Process App, the execution of the authorization of the employee is done outside the ERP: in a tool that is aimed to deliver approval schemes via a worklist-type of application. The Process App here works as an add-on to the PeopleSoft system, but can also be extended to support the full lifecycle of the end-to-end hiring process with the possibility to involve multiple applications. The actual core functionality is kept in the supporting ERP systems, while at the same time the Process App acts as an umbrella function to control the end-to-end flow and give insight into the efficiency of the end-to-end process.

• How to display Sharepoint Data in a Windows Forms Application

  - by Michael M. Bangoy

  In this post I'm going to demonstrate how to retrieve Sharepoint data and display it on a Windows Forms Application. 1. Open Visual Studio 2010 and create a new Project. 2. In the project template select Windows Forms Application. 3. In order to communicate with Sharepoint from a Windows Forms Application we need to add the 2 Sharepoint Client DLL located in c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI. 4. Select the Microsoft.Sharepoint.Client.dll and Microsoft.Sharepoint.Client.Runtime.dll. (Your solution should look like the one below) 5. Open the Form1 in design view and from the Toolbox menu Add a Button, TextBox, Label and DataGridView on the form. 6. Next double click on the Load Button, this will open the code view of the form. Add Using statement to reference the Sharepoint Client Library then create two method for the Load Site Title and LoadList. See below:   using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Security; using System.Windows.Forms; using SP = Microsoft.SharePoint.Client;   namespace ClientObjectModel {     public partial class Form1 : Form     {         // url of the Sharepoint site         const string _context = "theurlofthesharepointsite";         public Form1()         {             InitializeComponent();         }         private void Form1_Load(object sender, EventArgs e)         {                    }         private void getsitetitle()         {             SP.ClientContext context = new SP.ClientContext(_context);             SP.Web _site = context.Web;             context.Load(_site);             context.ExecuteQuery();             txttitle.Text = _site.Title;             context.Dispose();         }                 private void loadlist()         {             using (SP.ClientContext _clientcontext = new SP.ClientContext(_context))             {                 SP.Web _web = _clientcontext.Web;                 SP.ListCollection _lists = _clientcontext.Web.Lists;                 _clientcontext.Load(_lists);                 _clientcontext.ExecuteQuery();                 DataTable dt = new DataTable();                 DataColumn column;                 DataRow row;                 column = new DataColumn();                 column.DataType = Type.GetType("System.String");                 column.ColumnName = "List Title";                 dt.Columns.Add(column);                 foreach (SP.List listitem in _lists)                 {                     row = dt.NewRow();                     row["List Title"] = listitem.Title;                     dt.Rows.Add(row);                 }                 dataGridView1.DataSource = dt;             }                   }       private void cmdload_Click(object sender, EventArgs e)         {             getsitetitle();             loadlist();          }     } } 7. That’s it. Hit F5 to run the application then click the Load Button. Your screen should like the one below. Hope this helps.

• What version-control system is most trivial to set up and use for toy projects?

  - by Norman Ramsey

  I teach the third required intro course in a CS department. One of my homework assignments asks students to speed up code they have written for a previous assignment. Factor-of-ten speedups are routine; factors of 100 or 1000 are not unheard of. (For a factor of 1000 speedup you have to have made rookie mistakes with malloc().) Programs are improved by a sequence is small changes. I ask students to record and describe each change and the resulting improvement. While you're improving a program it is also possible to break it. Wouldn't it be nice to back out? You can see where I'm going with this: my students would benefit enormously from version control. But there are some caveats: Our computing environment is locked down. Anything that depends on a central repository is suspect. Our students are incredibly overloaded. Not just classes but jobs, sports, music, you name it. For them to use a new tool it has to be incredibly easy and have obvious benefits. Our students do most work in pairs. Getting bits back and forth between accounts is problematic. Could this problem also be solved by distributed version control? Complexity is the enemy. I know setting up a CVS repository is too baffling---I myself still have trouble because I only do it once a year. I'm told SVN is even harder. Here are my comments on existing systems: I think central version control (CVS or SVN) is ruled out because our students don't have the administrative privileges needed to make a repository that they can share with one other student. (We are stuck with Unix file permissions.) Also, setup on CVS or SVN is too hard. darcs is way easy to set up, but it's not obvious how you share things. darcs send (to send patches by email) seems promising but it's not clear how to set it up. The introductory documentation for git is not for beginners. Like CVS setup, it's something I myself have trouble with. I'm soliciting suggestions for what source-control to use with beginning students. I suspect we can find resources to put a thin veneer over an existing system and to simplify existing documentation. We probably don't have resources to write new documentation. So, what's really easy to setup, commit, revert, and share changes with a partner but does not have to be easy to merge or to work at scale? A key constraint is that programming pairs have to be able to share work with each other and only each other, and pairs change every week. Our infrastructure is Linux, Solaris, and Windows with a netapp filer. I doubt my IT staff wants to create a Unix group for each pair of students. Is there an easier solution I've overlooked? (Thanks for the accepted answer, which beats the others on account of its excellent reference to Git Magic as well as the helpful comments.)

• SQL IO and SAN troubles

  - by James

  We are running two servers with identical software setup but different hardware. The first one is a VM on VMWare on a normal tower server with dual core xeons, 16 GB RAM and a 7200 RPM drive. The second one is a VM on XenServer on a powerful brand new rack server, with 4 core xeons and shared storage. We are running Dynamics AX 2012 and SQL Server 2008 R2. When I insert 15 000 records into a table on the slow tower server (as a test), it does so in 13 seconds. On the fast server it takes 33 seconds. I re-ran these tests several times with the same results. I have a feeling it is some sort of IO bottleneck, so I ran SQLIO on both. Here are the results for the slow tower server: C:\Program Files (x86)\SQLIO>test.bat C:\Program Files (x86)\SQLIO>sqlio -kW -t8 -s120 -o8 -frandom -b8 -BH -LS C:\Tes tFile.dat sqlio v1.5.SG using

However, the 64 write test is incredibly slow on the rack server. (68 mb/sec on the slow tower vs 21 mb/s on the rack). The read speed for 64k also seems slow. Is this enough to say there is some sort of bottleneck with the shared storage? I need to know if I can take this evidence and say we need to launch an investigation into this. Any help is appreciated.

• Unable to boot Windows 7 after installing Ubuntu

  I have Windows 7 on my machine and then installed Ubuntu 12.04 using a live CD. I can see both Windows 7 and Ubuntu in the grub menu, but when I select Windows 7 it shows a black screen for about 2 seconds and the returns to the Grub menu.

• SQL SERVER – Fix: Error: File cannot be loaded because the execution of scripts is disabled on this system. Please see “get-help about_signing” for more details

  - by pinaldave

  Yesterday I formatted my computer and did fresh install as it was due from long time. After the fresh install when I tried to install Semantic Search application using powershell, I was stopped by following error. File cannot be loaded because the execution of scripts is disabled on this system. Please see “get-help about_signing” for more details Fix/Solution/Workaround: The solution is very simple. Open the Powershell window and type following two lines and everything will fine right after that. Set-ExecutionPolicy Unrestricted Set-ExecutionPolicy RemoteSigned Again, this is I have done for my environment where I am very careful what I will run. You can change the policy back to original restricted policy if you want to restrict future execution of the powershell scripts. Simple – isn’t it? Well all complex looking problems are very simple to solve.

Update 1: My user is a member of administrators group. Other things work fine. When I try to change something that needs administrative permission, UAC window appears, but nothing here.
