• Virtual Box - How to open a .VDI Virtual Machine

  - by [email protected]

  TUESDAY, APRIL 27, 2010 How to open a .VDI Virtual MachineSometimes someone share with us one Virtual machine with extension .VDI, after that we can wonder how and what with?Well the answer is... It is a VirtualBox - Virtual Machine. If you have not downloaded it you can do this easily just follow this post.http://listeningoracle.blogspot.com/2010/04/que-es-virtualbox.htmlorhttp://oracleoforacle.wordpress.com/2010/04/14/ques-es-virtualbox/Ok, Now with VirtualBox Installed open it and proceed with the following:1. Open the Virtual File Manager.2. Click on Actions ? Add and select the .VDI fileClick "Ok"3. Now we can register the new Virtual Machine - Click New, and Click Next4. Write down a Name for the virtual Machine a proceed to select a Operating System and Version. (In this case it is a Linux (Oracle Enterprise Linux or RedHat)Click Next5. Select the memory amount base for the Virtual Machine(Minimal 1280 for our case) - Click Next6. Select the Disk 11GR2_OEL5_32GB.vdi it was added in the virtual media manager in the step 2.Dont forget let selected Boot hard Disk (Primary Master) . Given it is the only disk assigned to the virtual machine.Click Next7. Click Finish8. This step is important. Once you have click on the settings Button. 9. On General option click the advanced settings. Here you must change the default directory to save your Snapshots; my recommendation set it to the same directory where the .Vdi file is. Otherwise you can have the same Virtual Machine and its snapshots in different paths.10. Now Click on System, and proceed to assign the correct memory (If you did not before)Note: Enable "Enable IO APIC" if you are planning to assign more than one CPU to the Virtual Machine.Define the processors for the Virtual machine. If you processor is dual core choose 211. Select the video memory amount you want to assign to the Virtual Machine12. Associated more storage disk to the Virtual machine, if you have more VDI files.(Not our case)The disk must be selected as IDE Primary Master.13. Well you can verify the other options, but with these changes you will be able to start the VM.Note: Sometime the VM owner may share some instructions, if so follow his instructions.14. Finally Start the Virtual Machine (Click > Start)

• No sound in Ubuntu except at log in

  - by Mohd Arafat Hossain

  I installed Ubuntu 12.04 a month ago and am using it till now. I failed to notice that all this time there was no sound at all while running Ubuntu, even while playing a game in Wine. The weird thing is that only the startup sound comes when I log in (Indian/African drum tone), then comes the utter silence. I tested both Digital Output (S/PDIF) and the speakers in the sound settings but can hear nothing. Any help?

• SQL SERVER – How to Roll Back SQL Server Database Changes

  - by Pinal Dave

  In a perfect scenario, no unexpected and unplanned changes occur. There are no unpleasant surprises, no inadvertent changes. However, even with all precautions and testing, there is sometimes a need to revert a structure or data change. One of the methods that can be used in this situation is to use an older database backup that has the records or database object structure you want to revert to. For this method, you have to have the adequate full database backup and a tool that will help you with comparison and synchronization is preferred. In this article, we will focus on another method: rolling back the changes. This can be done by using: An option in SQL Server Management Studio T-SQL, or ApexSQL Log The first two solutions have been described in this article The disadvantages of these methods are that you have to know when exactly the change you want to revert happened and that all transactions on the database executed in a specific time range are rolled back – the ones you want to undo and the ones you don’t. How to easily roll back SQL Server database changes using ApexSQL Log? The biggest challenge is to roll back just specific changes, not all changes that happened in a specific time range. While SQL Server Management Studio option and T-SQL read and roll forward all transactions in the transaction log files, I will show you a solution that finds and scripts only the specific changes that match your criteria. Therefore, you don’t need to worry about all other database changes that you don’t want to roll back. ApexSQL Log is a SQL Server disaster recovery tool that reads transaction logs and provides a wide range of filters that enable you to easily rollback only specific data changes. First, connect to the online database where you want to roll back the changes. Once you select the database, ApexSQL Log will show its recovery model. Note that changes can be rolled back even for a database in the Simple recovery model, when no database and transaction log backups are available. However, ApexSQL Log achieves best results when the database is in the Full recovery model and you have a chain of subsequent transaction log backups, back to the moment when the change occurred. In this example, we will use only the online transaction log. In the next step, use filters to read only the transactions that happened in a specific time range. To remove noise, it’s recommended to use as many filters as possible. Besides filtering by the time of the transaction, ApexSQL Log can filter by the operation type: Table name: As well as transaction state (committed, aborted, running, and unknown), name of the user who committed the change, specific field values, server process IDs, and transaction description. You can select only the tables affected by the changes you want to roll back. However, if you’re not certain which tables were affected, you can leave them all selected and once the results are shown in the main grid, analyze them to find the ones you to roll back. When you set the filters, you can select how to present the results. ApexSQL Log can automatically create undo or redo scripts, export the transactions into an XML, HTML, CSV, SQL, or SQL Bulk file, and create a batch file that you can use for unattended transaction log reading. In this example, I will open the results in the grid, as I want to analyze them before rolling back the transactions. The results contain information about the transaction, as well as who and when made it. For UPDATEs, ApexSQL Log shows both old and new values, so you can easily see what has happened. To create an UNDO script that rolls back the changes, select the transactions you want to roll back and click Create undo script in the menu. For the DELETE statement selected in the screenshot above, the undo script is: INSERT INTO [Sales].[PersonCreditCard] ([BusinessEntityID], [CreditCardID], [ModifiedDate]) VALUES (297, 8010, '20050901 00:00:00.000') When it comes to rolling back database changes, ApexSQL Log has a big advantage, as it rolls back only specific transactions, while leaving all other transactions that occurred at the same time range intact. That makes ApexSQL Log a good solution for rolling back inadvertent data and schema changes on your SQL Server databases.

• Ubuntu 10.10 Network Issues (wireless as well as wired)

  - by user9054

  down vote favorite Hi Friends, I have got this issue with Ubuntu 10.10 . I have been with ubuntu 8.04 and then decided to try out ubuntu 10.10 . I booted with a LiveCD and was able to configure the wireless network painlessly using the livecd . so happily i installed ubuntu 10.10 . As soon as ubuntu came up it detected the wireless network and i was able to assign a static IP to eth1 (i dont use DHCP option on my ADSL router) and enter a wap key and use pppoeconf to configure the dialer . The net was on and i was able to surf the net . all hunky dory so far . However on the next boot the fun started . It did not detect the wireless network . I could not see the network manager icon in the systray . I used ifconfig and saw that the entry for eth1 was missing .I used ifup eth1 and it said that eth1 was already up . Then i installed wifi-radar . Wifi-Radar detected the wireless network . I configured wifi-radar for the detected wireless network , set the wap driver as wext and used the manual IP settings . However on clicking connect wifi-radar started looking for a DHCP IP , needless to say it failed . For the love of god i cannot understand why wifi-radar is using DHCP when i have specified manual settings . Next i decided to use the wired network to surf the net looking for a solution . So i plugged in the network cable from my modem , it detected the plugged in connection , i configured eth0 , used pppoeconf and connected to the net . Then i foolishly decided to reboot my PC . And wonders of wonders , the same problem appeared . I cannot see eth0 in my ifconfig anymore . i used pon to start the dsl-provider connection and it said something about network error or something . Now my ifconfig shows only lo , both eth0 and eth1 have disappeared .Can anybody help me on this ? Is it a problem with ipv6 , if so how do you disable ipv6 on ubuntu 10.10 ? OR is this is a known issue with ubuntu 10.10 ? .PS : 1) i tried linux mint 10 and had the same issue . on rebooting wireless network was not getting detected . 2) i have made myself the administrator so that there is no issue of rights or anything. Any help is appreciated.

• Is there any way to lock down Photoshop to prevent designers from creating styles that cannot be rendered in CSS?

  - by Hugo Rodger-Brown

  Photoshop is a much more powerful design tool than CSS, and given free reign to design at will, designers will often tweak things like font settings to a degree that cannot be recreated on the web. Is there any way to lock down Photoshop, or perhaps run an equivalent of the Office 2010 "Compatability report" that shows the designer where they have designed something that cannot be rendered on a web page. Something like the old-school "web-safe" colour palette, but for an overall design.

• How do I fix the problems I'm having with Xfce and Xubuntu?

  - by Noel Quiles

  I booted into a Xubuntu session and when the splash disappeared it left behind artifacts on the desktop. I went into Desktop to change the background but it stayed completely gray. Not only that, GTK isn't theming any of my windows, nor can I change GTK themes in the settings manager. I recently installed GTK+ 2.x alongside GTK+ 3 for a compatibility issue with xfce-battery-plugin, which also refuses to show anything but 0%. What is going on?

• ubuntu i3wm freezes on login

  - by NaN

  I switched to the i3 window manager, which is quite nice, but I have a funny bug. If I reboot and set the wm to i3 (within the lightdb settings) the gui freezes after logging in (i can see the light-db background image and login-form and the i3status bar at the same time, but nothing reacts). To use the system like expected I have to use unity, log out and login (with i3) again. How can I debug this bug?

• User connection management in Reporting Services configuration

  - by Testas

  IT professionals will use Reporting Services Configuration Manager to perform post installation tasks for SQL Server Reporting Services. Introduced in SQL Server 2005, Reporting Services Configuration Manager provides an intuitive interface to perform tasks including specifying the report server database, report manager url, and indeed one of the first post installation tasks that should be performed is backing up the encryption keys that are used to protect the sensitive information within the rdl files.  Many of the options that are selected within Reporting Services Configuration Manager are written to a number of configuration files including the rsreportserver.config file located in C:\Program Files\Microsoft SQL Server\Report Server InstanceName\Reporting Services\ReportServer folder.When opening this file you will notice that there are more configuration settings within the rsreportserver.config file than is available through the Reporting Services Configuration Manager Interface. As a result there are additional configuration options that can be defined within this file.  A customer was having a problem performing stress tests against a new Report Server that would be going live for an enterprise reporting system. One aspect of the stress test was to fire 50 connections from a single user account. When performing the stress test an error described that the maximum active request had been exceeded. Within the rsreportserver.config, there is a key that is added to the file:  <Add Key=”MaxActiveReqForOneUser” Value=”20”/>  Changing the value from 20 to 50 accommodated the needs of the stress test, however, a wider question should be asked pertaining to this setting when implementing Reporting Services to a production environment. Within an intranet environment, the default setting is appropriate when network bandwidth is high, users are known and demand for reports is particularly high from a group of users.  However, when deploying a Reporting Server solution to an extranet, or the internet, you may want to consider reducing this setting to reduce to scope of connections that can be acquired by a single user and placing unnecessary pressure on the report server. I do hope that Reporting Services Configuration Manager evolves to include an advanced page that includes an intuitive interface to change configuration settings such as the MaxActiveReqForOneUser, and also configure rendering and data extensions and define secure connection levels to the report server. All these options can be configured within the rsreportserver.config file, and these are setting that customers would like to see in Reporting Services Configuration Manager in the future.   If you think that the SQL community would benefit from this addition, you can vote on it at Microsoft Connect  https://connect.microsoft.com/SQLServer/feedback/details/565575/extending-reporting-services-configuration-manager-rscm

• Trouble with Wubi and dual boot install

  - by noam

  Is there a difference between wubi install and doing an install of Ubuntu alongside windows7? I ask because I used wubi, but I'm having trouble with certain things like being unable to change my brightness settings and I'm wondering if installing from a usb drive would change anything. Also, I've tried to do a usb drive install, but it doesn't give me the option to install alongside, it only shows the "Replace Windows 7" and "something else" options. Is this because I already did a wubi install?

• Xubuntu 14.04 resolution low

  - by user3203576

  I installed Xubuntu 14.04 amd64 on the computer at the computer repair shop where I work, but the screen resolution is way low, like 1024 x 768 (that wouldn't be low for a laptop or anything, but for a large desktop screen it is) I went to the display settings, but the resolution wouldn't go higher than that. When I installed Xubuntu 14.04 i386 at my computer at home, I didn't have any problems with the resolution. Any help? update: I ran lspci | grep VGA and got: 00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2)

• Why does LightDM only show a custom wallpaper on the login screen if I have selected one of the default wallpapers?

  - by Mauricio

  LightDM only changes wallpapers if I have selected one of the default wallpapers. If I choose another image from my pictures, LightDM shows the default wallpaper. Why is this happening, and how can I make LightDM show my wallpaper if it is not one of the defaults? As @doug said in his answer, it works if you click on the little + symbol in the appearance settings: after you do that, LightDM changes wallpapers.

• Indentify Codecs & Technical Information About Video Files

  - by DigitalGeekery

  Have you ever wanted to play an audio or video file but didn’t have the proper codec installed? Today we’ll show how to determine codecs, along with a host of other technical details about your media files with MediaInfo. Installation Download and install MediaInfo. You can find the download link at the bottom of the page. Note: When installing MediaInfo there is a recommended software bundle which you can opt out of by selecting Do not install option. Each recommended software choice may be different, like in this example it offers Spyware Terminator. The cool thing though is they use Open Candy which opts you out of the install. Just double check to make sure you’re not installing extra crapware. Using MediaInfo The first time you run MediaInfo it will display the Preferences window. There are various option such as language, output format, and whether or not you want MediaInfo to check for new versions. Click OK. Select a file or folder to analyze by clicking on the File or Folder icons on the left of the application window or by selecting File > Open from the menu. You can also drag and drop a file directly onto the application. MediaInfo will display details of your media file. In Basic view, you’ll see basic information. Notice in the example below the video and audio codecs, along with file size, running time of the media file, and even the application used to create the video file (Writing application).    You can switch to some of the other views by selecting View from the Menu and choosing form the dropdown list.   Sheet View will present the information a bit more clearly. You can see in the example below that the video and audio codec are listing in clearly identified columns. (AVC is often more commonly referred to H.264.)   Tree View is perhaps the most detailed. You can see from the example below the codec used for this AVI file is XviD.   Scrolling down even further you’ll see additional information like video and audio bit rates, frame rate, aspect ratio, and more.   In Basic View (and also in Sheet view) you can click to find a player for your file. In this instance with an MP4 file, it took me to the download page for Quicktime. This is by no means the only media player for this file, but if you are stuck for how to play a media file, this will forward you to a solution that works. You can do the same thing with Video codec. Click Go to the web site of this video codec to find a download.   MediaInfo is a simple but powerful tool that can be used to discover the details of a media file, or just to find a compatible codec. It works with most any video file type and is available for Windows, Mac, and Linux. Some Mac and Linux versions, however, are currently command line only.

• Using runtime checking of code contracts in Visual Studio 2010

  - by DigiMortal

  In my last posting about code contracts I introduced how to check input parameters of randomizer using static contracts checking. But you can also compile code contracts to your assemblies and use them also in runtime. In this posting I will show you simple example about runtime checking of code contracts. NB! If you want to play with code and try out things described here feel free to download example solution. if you are speaker and want to use this solution as a part of your sessions then feel free to do so, but don’t forget to refer me and this blog as source of this solution. And please let me know about your session. As a speaker I am very interested about it. :) To see how code contracts are checked at runtime we have to enable runtime checking from project properties. Make sure you have checked the box “Perform Runtime Contract Checking” and make sure you select “Full” from dropdown. These parts are in red box on the screenshot below. Visual Studio 2010 settings for code contracts. Runtime Checking is turned on and checks are made only in public surface. Click on image to see it at original size.  Save project settings. Then compile code and run it. As soon as code execution hits the call to GetRandomFromRangeContracted() exception is thrown. If you are not currently playing with solution referred above take a look at the following screenshot. Visual Studio 2010 runtime checking of code contracts. Exception of type ContractException is thrown when contract is violated. Click on image to see it at original size.  The exact type of exception is ContractException and it is defined in System.Diagnostics.Contracts.__ContractsRuntime namespace. In our example the message of exception is following: "Precondition failed: min < max  Min must be less than max" Besides the description we inserted for the case contract violation the message also contains violated contract type. In this case the type of contract is Precondition. Conclusion Using runtime checking of code contracts enables you to take code contracts with your code and have them checked every time when your methods are called. This way you can assure that all conditions are met to run method or exception is thrown and calling system has to handle the situation.

• Securing WebSocket applications on Glassfish

  - by Pavel Bucek

  Today we are going to cover deploying secured WebSocket applications on Glassfish and access to these services using WebSocket Client API. WebSocket server application setup Our server endpoint might look as simple as this: @ServerEndpoint("/echo") public class EchoEndpoint { @OnMessage   public String echo(String message) {     return message + " (from your server)";   } } Everything else must be configured on container level. We can start with enabling SSL, which will require web.xml to be added to your project. For starters, it might look as following: <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee">   <security-constraint>     <web-resource-collection>       <web-resource-name>Protected resource</web-resource-name>       <url-pattern>/*</url-pattern>       <http-method>GET</http-method>     </web-resource-collection>     <!-- https -->     <user-data-constraint>       <transport-guarantee>CONFIDENTIAL</transport-guarantee>     </user-data-constraint>   </security-constraint> </web-app> This is minimal web.xml for this task - web-resource-collection just defines URL pattern and HTTP method(s) we want to put a constraint on and user-data-constraint defines that constraint, which is in our case transport-guarantee. More information about these properties and security settings for web application can be found in Oracle Java EE 7 Tutorial. I have some simple webpage attached as well, so I can test my endpoint right away. You can find it (along with complete project) in Tyrus workspace: [webpage] [whole project]. After deploying this application to Glassfish Application Server, you should be able to hit it using your favorite browser. URL where my application resides is https://localhost:8181/sample-echo-https/ (may be different, depends on other configuration). My browser warns me about untrusted certificate (I use what freshly built Glassfish provides - self signed certificates) and after adding an exception for this site, I can see my webpage and I am able to securely connect to wss://localhost:8181/sample-echo-https/echo. WebSocket client Already mentioned demo application also contains test client, but execution of this is skipped for normal build. Reason for this is that Glassfish uses these self-signed "random" untrusted certificates and you are (in most cases) not able to connect to these services without any additional settings. Creating test WebSocket client is actually quite similar to server side, only difference is that you have to somewhere create client container and invoke connect with some additional info. Java API for WebSocket allows you to use annotated and programmatic way to construct endpoints. Server side shows the annotated case, so let's see how the programmatic approach will look. final WebSocketContainer client = ContainerProvider.getWebSocketContainer(); client.connectToServer(new Endpoint() {   @Override   public void onOpen(Session session, EndpointConfig EndpointConfig) {     try {       // register message handler - will just print out the       // received message on standard output.       session.addMessageHandler(new MessageHandler.Whole<String>() {       @Override         public void onMessage(String message) {          System.out.println("### Received: " + message);         }       });       // send a message       session.getBasicRemote().sendText("Do or do not, there is no try.");     } catch (IOException e) {       // do nothing     }   } }, ClientEndpointConfig.Builder.create().build(),    URI.create("wss://localhost:8181/sample-echo-https/echo")); This client should work with some secured endpoint with valid certificated signed by some trusted certificate authority (you can try that with wss://echo.websocket.org). Accessing our Glassfish instance will require some additional settings. You can tell Java which certificated you trust by adding -Djavax.net.ssl.trustStore property (and few others in case you are using linked sample). Complete command line when you are testing your service might need to look somewhat like: mvn clean test -Djavax.net.ssl.trustStore=$AS_MAIN/domains/domain1/config/cacerts.jks\ -Djavax.net.ssl.trustStorePassword=changeit -Dtyrus.test.host=localhost\ -DskipTests=false Where AS_MAIN points to your Glassfish instance. Note: you might need to setup keyStore and trustStore per client instead of per JVM; there is a way how to do it, but it is Tyrus proprietary feature: http://tyrus.java.net/documentation/1.2.1/user-guide.html#d0e1128. And that's it! Now nobody is able to "hear" what you are sending to or receiving from your WebSocket endpoint. There is always room for improvement, so the next step you might want to take is introduce some authentication mechanism (like HTTP Basic or Digest). This topic is more about container configuration so I'm not going to go into details, but there is one thing worth mentioning: to access services which require authorization, you might need to put this additional information to HTTP headers of first (Upgrade) request (there is not (yet) any direct support even for these fundamental mechanisms, user need to register Configurator and add headers in beforeRequest method invocation). I filed related feature request as TYRUS-228; feel free to comment/vote if you need this functionality.

• Application switcher is broken

  - by Byron Hawkins

  After a normal update of my Ubuntu 12.04 install last week, my application switcher has stopped working. I've tried all different settings in CompizConfig, including a variety of shortcut keys and both switcher versions ("Application Switcher" and "Static Application Switcher"). So far there has been no way to get any form of application switcher to appear on my screen. Can anyone give me an idea what might be wrong, or where I might look for more information? Thanks for your help.
