  • Two python distributions, sudo picking the wrong one

    - by DHK
    I'm back to Linux after an over 10 year abstinence (fool me thinks). And a little rusty in the sys admin department. I'm faced with an issue with my python distribution. I'm using Python 2.7, but based on the Anaconda flavour. I followed the standard guidance but recently I discovered an issue that I'm not sure how to fix. Under sudo, the standard Python as comes with Ubuntu is provided. Under my user account python points to the Anaconda version: dhk@localhost:~/home/$which python /opt/anaconda/bin/python dhk@localhost:~/home/$sudo which python /usr/bin/python This is an issue as using sudo pip [anything] usually acts on the wrong directory, yet I cannot use it without sudo.

  • Difference between 12.04 and 12.04.1

    - by Jeff
    I recently did a fresh install of Ubuntu 12.04 two days ago. Or at least I thought it was 12.04, but actually 12.04.1. Now I'm having errors popping up from the grub loader. Error: no video mode activated which was apparently resolved in this bug# 699802. However these workarounds are for 11.xx and not working for me. I never had these errors before with 12.04 and now I'm getting them. What's the difference between 12.04 and 12.04.1? Off the bat I notice that the kernels are different 12.04 uses 3.2.0-26-generic-pae 12.04.1 uses 3.2.0-29-generic after an immediate sudo apt-get update upgrade 12.04.1 uses 3.2.0-30-generic I have two other computers running 12.04 (not 12.04.1) and they're working fine. The computer that I'm currently was working fine (with 12.04) previously too. Should I roll back my kernel to 3.2.0-26?

  • EBS + 11g Database Upgrade Best Practices Whitepaper Available

    - by Steven Chan
    I returned from OAUG/Collaborate with a cold and multiple overlapping development crises.  Fun.  Now that those are (mostly) out of the way, it's time to get back to clearing out my article backlog.  Premier Support for the 10gR2 database ends in July 2010.  If you haven't already started planning your 11g database upgrade, we recommend that you start soon.  We have certified both the 11gR1 (11.1.0.7) and 11gR2 (11.2.0.1) databases with Oracle E-Business Suite; see this blog's Certification summary to links to articles with the details.Our Applications Performance Group has reminded me that they have a whitepaper loaded with practical tips intended to make your 11g database upgrade easier.  No vacuous marketing rhetoric here -- this is strictly written for DBAs.  A must-read if you haven't already upgraded to either 11gR1 or 11gR2, and highly recommended even if you have.  You can download this whitepaper here:Upgrade to 11g Performance Best Practices (PDF, 184K)

  • Building a database installer with WiX, datadude and Visual Studio 2010

    - by jamiet
    Today I have been using Windows Installer XML (WiX) to build an installer (.msi file) that would install a SQL Server database on a server of my choosing; the source code for that database lives in datadude (a tool which you may know by one of quite a few other names). The basis for this work was a most excellent blog post by Duke Kamstra entitled Implementing a WIX installer that calls the GDR version of VSDBCMD.EXE which coves the delicate intricacies of doing this – particularly how to call Vsdbcmd.exe in a CustomAction. Unfortunately there are a couple of things wrong with Duke’s post: Searching for “datadude wix” didn’t turn it up in the first page of search results and hence it took me a long time to find it. And I knew that it existed. If someone else were after a post on using WiX with datadude its likely that they would never have come across Duke’s post and that would be a great shame because its the definitive post on the matter. It was written in October 2009 and had not been updated for Visual Studio 2010. Well, this blog post is an attempt to solve those problems. Hopefully I’ve solved the first one just by following a few of my blogging SEO tips while writing this blog post, in the rest of it I will explain how I took Duke’s code and updated it to work in Visual Studio 2010. If you need to build a database installer using WiX, datadude and Visual Studio 2010 then you still need to follow Duke’s blog post so go and do that now. Below are the amendments that I made that enabled the project to get built in Visual Studio 2010: In VS2010 datadude’s output files have changed from being called Database.<suffix> to <ProjectName>_Database.<suffix>. Duke’s code was referencing the old file name formats. Duke used $(var.SolutionDir) and relative paths to point to datadude artefacts I have replaced these with Votive Project References http://wix.sourceforge.net/manual-wix3/votive_project_references.htm I commented out all references to MicrosoftSqlTypesDbschema in DatabaseArtifacts.wxi. I don't think this is produced in VS2010 (I may be wrong about that but it wasn't in the output from my project) Similarly I commented out component MicrosoftSqlTypesDbschema in VsdbcmdArtifacts.wxi. It wasn't where Duke's code said it should have been so am assuming/hoping it isn't needed. Duke's ?define block to work out appropriate SrcArchPath actually wasn't working for me (i.e. <?if $(var.Platform)=x64 ?> was evaluating to false)  so I just took out the conditional stuff and declared the path explicitly to the “Program Files (x86)” path. The old code is still there though if you need to put it back. None of the <RegistrySearch> stuff is needed for VS2010 - so I commented it all out! Changed to use /manifest option rather than /model option on vsdbcmd.exe command-line. Personal preference is all! Added a new component in order to bundle along the vsdbcmd.exe.config file Made the install of the Custom Action dependent on the relevant feature being selected for install. This one is actually really important – deselecting the database feature for installation does not, by default, stop the CustomAction from executing and so would cause an error - so that scenario needs to be catered for I have made my amended solution available for download at: http://cid-550f681dad532637.office.live.com/self.aspx/Public/BlogShare/20110210/InstallMyDatabase.zip It contains two projects: the WiX project and the datadude project that is the source to be deployed (for demo purposes it only contains one table). I have also made the .msi available although in order that it gets through file blockers I changed the name from InstallMyDatabase.msi to InstallMyDatabase.ms_ – simply rename the file back once you have downloaded it from: http://cid-550f681dad532637.office.live.com/self.aspx/Public/BlogShare/20110210/InstallMyDatabase.ms%5E_ .You can try it out for yourself – the only thing it does is dump the files into %Program Files%\MyDatabase and uses them to install a database onto a server of your choosing with a name of your choosing - no damaging side-affects. I will caveat this by saying “it works on my machine” and, not having access to a plethora of different machines, I haven’t tested it anywhere else. One potential issue that I know of is that Vsdbcmd.exe has a dependency on SQL Server CE although if you have SQL Server tools or Visual Studio installed you should be fine. Unfortunately its not possible to bundle along the SQL Server CE installer in the .msi because Windows will not allow you to call one installer from inside another – the recommended way to get around this problem is to build a bootstrapper to bundle the whole lot together but doing that is outside the scope of this blog post. If you discover any other issues then please let me know. Here are the screenshots from the installer: And once installed…. Hope this is useful! @jamiet

  • SQL SERVER – Simple Example of Snapshot Isolation – Reduce the Blocking Transactions

    - by pinaldave
    To learn any technology and move to a more advanced level, it is very important to understand the fundamentals of the subject first. Today, we will be talking about something which has been quite introduced a long time ago but not properly explored when it comes to the isolation level. Snapshot Isolation was introduced in SQL Server in 2005. However, the reality is that there are still many software shops which are using the SQL Server 2000, and therefore cannot be able to maintain the Snapshot Isolation. Many software shops have upgraded to the later version of the SQL Server, but their respective developers have not spend enough time to upgrade themselves with the latest technology. “It works!” is a very common answer of many when they are asked about utilizing the new technology, instead of backward compatibility commands. In one of the recent consultation project, I had same experience when developers have “heard about it” but have no idea about snapshot isolation. They were thinking it is the same as Snapshot Replication – which is plain wrong. This is the same demo I am including here which I have created for them. In Snapshot Isolation, the updated row versions for each transaction are maintained in TempDB. Once a transaction has begun, it ignores all the newer rows inserted or updated in the table. Let us examine this example which shows the simple demonstration. This transaction works on optimistic concurrency model. Since reading a certain transaction does not block writing transaction, it also does not block the reading transaction, which reduced the blocking. First, enable database to work with Snapshot Isolation. Additionally, check the existing values in the table from HumanResources.Shift. ALTER DATABASE AdventureWorks SET ALLOW_SNAPSHOT_ISOLATION ON GO SELECT ModifiedDate FROM HumanResources.Shift GO Now, we will need two different sessions to prove this example. First Session: Set Transaction level isolation to snapshot and begin the transaction. Update the column “ModifiedDate” to today’s date. -- Session 1 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN UPDATE HumanResources.Shift SET ModifiedDate = GETDATE() GO Please note that we have not yet been committed to the transaction. Now, open the second session and run the following “SELECT” statement. Then, check the values of the table. Please pay attention on setting the Isolation level for the second one as “Snapshot” at the same time when we already start the transaction using BEGIN TRAN. -- Session 2 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that the values in the table are still original values. They have not been modified yet. Once again, go back to session 1 and begin the transaction. -- Session 1 COMMIT After that, go back to Session 2 and see the values of the table. -- Session 2 SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that the values are yet not changed and they are still the same old values which were there right in the beginning of the session. Now, let us commit the transaction in the session 2. Once committed, run the same SELECT statement once more and see what the result is. -- Session 2 COMMIT SELECT ModifiedDate FROM HumanResources.Shift GO You will notice that it now reflects the new updated value. I hope that this example is clear enough as it would give you good idea how the Snapshot Isolation level works. There is much more to write about an extra level, READ_COMMITTED_SNAPSHOT, which we will be discussing in another post soon. If you wish to use this transaction’s Isolation level in your production database, I would appreciate your comments about their performance on your servers. I have included here the complete script used in this example for your quick reference. ALTER DATABASE AdventureWorks SET ALLOW_SNAPSHOT_ISOLATION ON GO SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 1 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN UPDATE HumanResources.Shift SET ModifiedDate = GETDATE() GO -- Session 2 SET TRANSACTION ISOLATION LEVEL SNAPSHOT BEGIN TRAN SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 1 COMMIT -- Session 2 SELECT ModifiedDate FROM HumanResources.Shift GO -- Session 2 COMMIT SELECT ModifiedDate FROM HumanResources.Shift GO Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: Pinal Dave, SQL, SQL Authority, SQL Performance, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: Transaction Isolation

  • Manchester UG Presentation Video

    In July I was invited to speak at the UK SQL Server UG event in Manchester.  I spoke about Excel being a good data mining client.  I was a little rushed at the end as Chris Testa-ONeill told me I had only 5 minutes to go when I had only been talking for 10 minutes.  Apparently I have a reputation for running over my time allocation.  At the event we also had a product demo from SQL Sentry around their BI monitoring dashboard solution.  This includes SSIS but the main thrust was SSAS Then came Chris with a look at Analysis Services.  If you have never heard Chris talk then take the opportunity now, he is a top class presenter and I am often found sat at the back of his classes.

  • How to enable 3D acceleration under VMware workstation 8, Ubuntu 11.10 host, Ubuntu 11.10 guest

    - by Yan Zhou
    I saw there are similar questions, but I don't think they answer exactly my questions. Did anyone managed to get 3D acceleration work under VMWare workstation 8? I have VMware 8.01 installed on Ubuntu 11.10. The guest I am trying is also Ubuntu 11.10. I manually installed vmware-tools and it went well, except the X-config part was skipped as it said the distribution driver is used. The guest runs well but it seems fall back to 2D mode. Does any one has any idea how to enable 3D acceleration under VMWare workstaion with Linux guest?

  • Change the User Interface Language in Ubuntu

    - by Matthew Guay
    Would you like to use your Ubuntu computer in another language?  Here’s how you can easily change your interface language in Ubuntu. Ubuntu’s default install only includes a couple languages, but it makes it easy to find and add a new interface language to your computer.  To get started, open the System menu, select Administration, and then click Language Support. Ubuntu may ask if you want to update or add components to your current default language when you first open the dialog.  Click Install to go ahead and install the additional components, or you can click Remind Me Later to wait as these will be installed automatically when you add a new language. Now we’re ready to find and add an interface language to Ubuntu.  Click Install / Remove Languages to add the language you want. Find the language you want in the list, and click the check box to install it.  Ubuntu will show you all the components it will install for the language; this often includes spellchecking files for OpenOffice as well.  Once you’ve made your selection, click Apply Changes to install your new language.  Make sure you’re connected to the internet, as Ubuntu will have to download the additional components you’ve selected. Enter your system password when prompted, and then Ubuntu will download the needed languages files and install them.   Back in the main Language & Text dialog, we’re now ready to set our new language as default.  Find your new language in the list, and then click and drag it to the top of the list. Notice that Thai is the first language listed, and English is the second.  This will make Thai the default language for menus and windows in this account.  The tooltip reminds us that this setting does not effect system settings like currency or date formats. To change these, select the Text Tab and pick your new language from the drop-down menu.  You can preview the changes in the bottom Example box. The changes we just made will only affect this user account; the login screen and startup will not be affected.  If you wish to change the language in the startup and login screens also, click Apply System-Wide in both dialogs.  Other user accounts will still retain their original language settings; if you wish to change them, you must do it from those accounts. Once you have your new language settings all set, you’ll need to log out of your account and log back in to see your new interface language.  When you re-login, Ubuntu may ask you if you want to update your user folders’ names to your new language.  For example, here Ubuntu is asking if we want to change our folders to their Thai equivalents.  If you wish to do so, click Update or its equivalents in your language. Now your interface will be almost completely translated into your new language.  As you can see here, applications with generic names are translated to Thai but ones with specific names like Shutter keep their original name. Even the help dialogs are translated, which makes it easy for users around to world to get started with Ubuntu.  Once again, you may notice some things that are still in English, but almost everything is translated. Adding a new interface language doesn’t add the new language to your keyboard, so you’ll still need to set that up.  Check out our article on adding languages to your keyboard to get this setup. If you wish to revert to your original language or switch to another new language, simply repeat the above steps, this time dragging your original or new language to the top instead of the one you chose previously. Conclusion Ubuntu has a large number of supported interface languages to make it user-friendly to people around the globe.  And since you can set the language for each user account, it’s easy for multi-lingual individuals to share the same computer. Or, if you’re using Windows, check out our article on how you can Change the User Interface Language in Vista or Windows 7, too!

  • Best Web Site Copying Software

    - by GregH
    I just wanted to get some opinions on the best "web site copying" software out there (free or commercial is fine). I have a site that I've recently become responsible for managing, and the previous consultant has not provided operating system access. As such, the plan is to re-host the web site. I realize there are a lot of different issues to consider in doing this. However, I don't have much choice in the matter now. The plan is to use web site copying software (ala HTTrack) to "rip" the web site, and then modify what is downloaded back in to a maintainable site. This, of course, involves HTML, css, javascript, etc on the front-end. I'd like to recover as much of the site as possible to make re-creating it as easy as possible. Your input is appreciated. Input on my approach is also appreciated. Thanks!

  • Dell Latitude E6520 overheating

    I'm a newcomer to Ubuntu 11.10. My laptop is a Dell Latitude E6520, Sandy Bridge platform. The system cooling fan is crazy all the time. I don't do any intensive tasks. I really hope my laptop doesn't become a mushroom cloud. I suppose there's no perfect way to solve this... Can I lower the CPU frequency? Jupiter 0.0.51 was installed (power save mode). Cooling worked in my Windows 7 system until I deleted it. (I won't go back to Windows 7.)

  • 3 tier architecture in objective-c

    - by hba
    I just finished reading the objective-c developer handbook from apple. So I pretty much know everything that there is to know about objective-c (hee hee hee). I was wondering how do I go about designing a 3-tier application in objective-c. The 3-tiers being a front-end application in Cocoa, a middle-tier in pure objective-c and a back-end (data access also in objective-c and mysql db). I'm not really interested in discussing why I'd need a 3-tier architecture, I'd like to narrow the discussion to the 'how'. For example, can I have 3 separate x-code projects one for each tier? If so how would I link the projects together. In java, I can export each tier as a jar file and form the proper associations.

  • data source does not support server-side data paging uisng asp.net Csharp

    - by Aamir Hasan
    Yesterday some one mail me and ask about data source does not support server side data paging.So i write the the solution here please if you have got this problem read this article and see the example code this will help you a Lot.The only change you have to do is in the DataBind().Here you have used the SqlDataReader to read data retrieved from the database, but SqlDataReader is forward only. You can not traverse back and forth on it.So the solution for this is using DataAdapter and DataSet.So your function may change some what like this private void DataBind(){//for grid viewSqlCommand cmdO;string SQL = "select * from TABLE ";conn.Open();cmdO = new SqlCommand(SQL, conn);SqlDataAdapter da = new SqlDataAdapter(cmdO);DataSet ds = new DataSet();da.Fill(ds);GridView1.Visible = true;GridView1.DataSource = ds;GridView1.DataBind();ds.Dispose();da.Dispose();conn.Close();} This surely works. The reset of your code is fine. Enjoy coding.

    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?

  • Visio 2010 forward engineer add-in for office 2010

    - by Ryan Ternier
    I have been scouring the internet for ages trying to see if there was a usable add-on for Visio 2010 that could export SQL Scripts. MS stopping putting that functionality in Visio since 2003 – which is a huge shame. Today I found an open source project from Alberto Ferrari. It’s an add-in for Visio 2010 that allows you to generate SQL Scripts from your DB diagram. It’s still in beta, and the source is available.   Check it out here:http://sqlblog.com/blogs/alberto_ferrari/archive/2010/04/16/visio-forward-engineer-addin-for-office-2010.aspx This saves me from having to do all my diagramming in SQL Server / VS 2010. And brings back the much needed functionality that has been lost.

If, when running Event Store you may see the following message, [03288,15,06:23:00.622] Failed to start http server Access is denied You will either need to run Event Store in an administrator console window, or you can use the netsh command to create a firewall permission to allow HTTP listening (this will need to be run, once, in an administrator console window), netsh http add urlacl url=http://*:2213/ user=liam You can always delete this later by running the delete; netsh http delete urlacl url=http://*:2213/ If you want to confirm that everything is running OK, open the management console in a browser by navigating to http://127.0.0.1:2213. If at any point you are asked for a user name and password use the default of ‘admin’/‘changeit’. Demonstration 2 (reading and adding data, curl) In my second demonstration I used curl directly from the console to read streams, write events and then read back those events. On GitHub I have included is a set of curl commands, CurlCommandLine.txt, and a sample data file, SampleData.json, to load an event into a DDDNorth3 stream. As there is not much data in the Event Store at this point I used the $stats-127.0.0.1:2113 which is a stream containing performance statistics for Event Store and is updated every 30 seconds (default). Demonstration 3 (projections) On GitHub I have included a sample projection, Projection-ByRoom.txt, which will create streams based on the room on which a session was held on the DDDNorth3 agenda. Browse to the management console, http://127.0.0.1:2213.  Click on Projections, New Projection, give it a name, Sessions-ByRoom, and copy in the JavaScript in the Projection-ByRoom.txt file.  Select Continuous, tick Emit Enabled and then click on Post. It should run immediately. You may by challenged for the administration login for the management console, if so use the default user name and password; 'admin'/'changeit'. Demonstration 4 (C# client) The final demonstration was the Visual Studio 2012 project using the Event Store client – referenced directly as C:\EventStore\v2.0.1\EventStore.ClientAPI.dll, although you can switch this to the latest Event Store client NuGet package. The source code provides a console app for viewing projections with the projection manager (HTTP connection), as well as containing a full set of data for the entire DDDNorth3 agenda.  It also deals with the strategy for reading newest events backwards to older events and ignoring older events that have been superseded.

  • How To Replace Notepad in Windows 7

    - by Trevor Bekolay
    It used to be that Notepad was a necessary evil because it started up quickly and let us catch a quick glimpse of plain text files. Now, there are a bevy of capable Notepad replacements that are just as fast, but also have great feature sets. Before following the rest of this how-to, ensure that you’re logged into an account with Administrator access. Note: The following instructions involve modifying some Windows system folders. Don’t mess anything up while you’re in there! If you follow our instructions closely, you’ll be fine. Choose your replacement There are a ton of great Notepad replacements, including Notepad2, Metapad, and Notepad++. The best one for you will depend on what types of text files you open and what you do with them. We’re going to use Notepad++ in this how-to. The first step is to find the executable file that you’ll replace Notepad with. Usually this will be the only file with the .exe file extension in the folder where you installed your text editor. Copy the executable file to your desktop and try to open it, to make sure that it works when opened from a different folder. In the Notepad++ case, a special little .exe file is available for the explicit purpose of replacing Notepad.If we run it from the desktop, it opens up Notepad++ in all its glory. Back up Notepad You will probably never go back once you switch, but you never know. You can backup Notepad to a special location if you’d like, but we find it’s easiest to just keep a backed up copy of Notepad in the folders it was originally located. In Windows 7, Notepad resides in: C:\Windows C:\Windows\System32 C:\Windows\SysWOW64 in 64-bit versions only Navigate to each of those directories and copy Notepad. Paste it into the same folder. If prompted, choose to Copy, but keep both files. You can keep your backup as “notepad (2).exe”, but we prefer to rename it to “notepad.exe.bak”. Do this for all of the folders that have Notepad (2 total for 32-bit Windows 7, 3 total for 64-bit). Take control of Notepad and delete it Even if you’re on an administrator account, you can’t just delete Notepad – Microsoft has made some security gains in this respect. Fortunately for us, it’s still possible to take control of a file and delete it without resorting to nasty hacks like disabling UAC. Navigate to one of the directories that contain Notepad. Right-click on it and select Properties.   Switch to the Security tab, then click on the Advanced button. Note that the owner of the file is a user called “TrustedInstaller”. You can’t do much with files owned by TrustedInstaller, so let’s take control of it. Click the Edit… button. Select the desired owner (you could choose your own account, but we’re going to give any Administrator control) and click OK. You’ll get a message that you need to close and reopen the Properties windows to edit permissions. Before doing that, confirm that the owner has changed to what you selected. Click OK, then OK again to close the Properties window. Right-click on Notepad and click on Properties again. Switch to the Security tab. Click on Edit…. Select the appropriate group or user name in the list at the top, then add a checkmark in the checkbox beside Full control in the Allow column. Click OK, then Yes to the dialog box that pops up. Click OK again to close the Properties window. Now you can delete Notepad, by either selecting it and pressing Delete on the keyboard, or right-click on it and click Delete.   You’re now free from Notepad’s foul clutches! Repeat this procedure for the remaining folders (or folder, on 32-bit Windows 7). Drop in your replacement Copy your Notepad replacement’s executable, which should still be on your desktop. Browse to the two or three folders listed above and copy your .exe to those locations. If prompted for Administrator permission, click Continue. If your executable file was named something other than “notepad.exe”, rename it to “notepad.exe”. Don’t be alarmed if the thumbnail still shows the old Notepad icon. Double click on Notepad and your replacement should open. To make doubly sure that it works, press Win+R to bring up the Run dialog box and enter “notepad” into the text field. Press enter or click OK. Now you can allow Windows to open files with Notepad by default with little to no shame! All without restarting or having to disable UAC!

  • Create a Persistent Bootable Ubuntu USB Flash Drive

    - by Trevor Bekolay
    Don’t feel like reinstalling an antivirus program every time you boot up your Ubuntu flash drive? We’ll show you how to create a bootable Ubuntu flash drive that will remember your settings, installed programs, and more! Previously, we showed you how to create a bootable Ubuntu flash drive that would reset to its initial state every time you booted it up. This is great if you’re worried about messing something up, and want to start fresh every time you start tinkering with Ubuntu. However, if you’re using the Ubuntu flash drive to diagnose and solve problems with your PC, you might find that a lot of problems require guess-and-test cycles. It would be great if the settings you change in Ubuntu and the programs you install stay installed the next time you boot it up. Fortunately, Universal USB Installer, a great little program from Pen Drive Linux, can do just that! Note: You will need a USB drive at least 2 GB large. Make sure you back up any files on the flash drive because this process will format the drive, removing any files currently on it. Once Ubuntu has been installed on the flash drive, you can move those files back if there is enough space. Put Ubuntu on your flash drive Universal-USB-Installer.exe does not need to be installed, so just double click on it to run it wherever you downloaded it. Click Yes if you get a UAC prompt, and you will be greeted with this window. Click I Agree. In the drop-down box on the next screen, select Ubuntu 9.10 Desktop i386. Don’t worry if you normally use 64-bit operating systems – the 32-bit version of Ubuntu 9.10 will still work fine. Some useful tools do not have 64-bit versions, so unless you’re planning on switching to Ubuntu permanently, the 32-bit version will work best. If you don’t have a copy of the Ubuntu 9.10 CD downloaded, then click on the checkbox to Download the ISO. You’ll be prompted to launch a web browser; click Yes. The download should start immediately. When it’s finished, return the the Universal USB Installer and click on Browse to navigate to the ISO file you just downloaded. Click OK and the text field will be populated with the path to the ISO file. Select the drive letter that corresponds to the flash drive that you would like to use from the dropdown box. If you’ve backed up the files on this drive, we recommend checking the box to format the drive. Finally, you have to choose how much space you would like to set aside for the settings and programs that will be stored on the flash drive. Considering that Ubuntu itself only takes up around 700 MB, 1 GB should be plenty, but we’re choosing 2 GB in this example because we have lots of space on this USB drive. Click on the Create button and then make yourself a sandwich – it will take some time to install no matter how fast your PC is. Eventually it will finish. Click Close. Now you have a flash drive that will boot into a fully capable Ubuntu installation, and any changes you make will persist the next time you boot it up! Boot into Ubuntu If you’re not sure how to set your computer to boot using the USB drive, then check out the How to Boot Into Ubuntu section of our previous article on creating bootable USB drives, or refer to your motherboard’s manual. Once your computer is set to boot using the USB drive, you’ll be greeted with splash screen with some options. Press Enter to boot into Ubuntu. The first time you do this, it may take some time to boot up. Fortunately, we’ve found that the process speeds up on subsequent boots. You’ll be greeted with the Ubuntu desktop. Now, if you change settings like the desktop resolution, or install a program, those changes will be permanently stored on the USB drive! We installed avast! Antivirus, and on the next boot, found that it was still in the Accessories menu where we left it. Conclusion We think that a bootable Ubuntu USB flash drive is a great tool to have around in case your PC has problems booting otherwise. By having the changes you make persist, you can customize your Ubuntu installation to be the ultimate computer repair toolkit!

  • SQLAuthority News – Meeting with Allen Bailochan Tuladhar – An Unlimited Experience

    - by pinaldave
    Allen  Tuladhar I recently came back from my 9-day trip in Nepal and I must say that this is one of the best trips I had in my lifetime. Allen Bailochan Tuladhar is a wonderful person and an extreme enthusiast for Microsoft Technology. Allen is the Chief Executive Officer of Unlimited Technologies Pvt Ltd., Country Manager of Microsoft MDP Nepal, the Member Secretary of Nepali Language in Information Technology, and member of the Steering Committee of the Government of Nepal. He is the person who keeps the Nepal’s Tech Community constantly motivating and taking it to the next level. I have met Allen for many times before, but this was the first time I was with him in Kathmandu, Nepal. I was very impressed with the amount of the work he does in the community. During my 9 days of stay, every single day was a new lesson for me. I was amazed and overwhelmed with the many things he does every single day. Not only he does he work closely with Government of Nepal ministry, but he is also the most known person in the Student Community. His expertise in the technical subject matter is not limited to one technology; rather, I have seen him actively engaging himself in  discussions of various tech topics. Allen presending at TechMela Kathmandu, Nepal Allen is currently active in working out to localize Windows and Office and incorporate it using the Nepali language. I was able to witness and experience how the localization works, as well as the procedure on how to do such. If you know the whole localization process, you must have realized how big and daunting of a process it is. I was glad that I became a part of it. Prominent Personality of Nepal on Panel Discussion Another great opportunity I had when I was at Allen’s office is that I have learned how the radio technology talk show works. Nepali Radio station has the weekly program in their local language, in which MS technology is discussed and industry leaders are invited to talk about their experience with the technology. I found the program so interesting because it has so much variety in terms of technology subjects. Well, my understanding of Nepali language is limited but I did understand quite a bit. Ravi, Nutan, Pinal, Gandip I got the chance to meet lots of Database Professionals as well. People in Nepal are very polite even though they are very strong in their technology fundamentals. I had in-depth discussion regarding High Availability scenarios, as well Query Tuning. Database professionals from the leading financial sectors of Nepal wanted me to visit their Data Center and help them out with a few advances. In no time, Allen organized a visit for me. He sent me a Nepali-speaking expert from his own organization to accompany me in overcoming any difficulties while I was on my way helping this financial district. Pinal (SQLAuthority) and Deependra (Unlimited) When I was going to Nepal, I was really not sure if I would be able to stay busy for 9 days straight in Community-related activity. However, on the 9th day I realize that I can still stay here for more than 9 days because in every single day, I feel enthusiastic enough to do something new. Allen Bailochan Tuladhar Even though I was working  very hard every day, I hardly had the chance to work with and talk to him one-on-one for the first few days. One of the evenings, Allen invited me to his home and we discussed about his future ideas. I was really surprised to see how much a man can do for his technical community and for his country. When I asked Allen’s wife and daughter if they ever think it’s getting too much with regards to Allen putting tough efforts to the community, their answer was something I did not expect. I found out that Allen’s wife manages all the back office and logistics of the community events and his daughter manages the websites. I felt that they do not have any complain,  and instead, their whole family is in this activity as deeply as it can get, which I thought is a very good thing. Pinal and Allen I want to end this post with an interesting story that happened during our lunch hour at one of the Nepali restaurants. While we were having our lunch and having some chitchat, Allen suddenly stood up and called several people walking along the pavement. He introduced them all to me as Microsoft Student Partners. He asked all of them to order their favorite dish and called the waiter to inform that he will pick up their tab. Figuring out the question written on my face, he just said one sentence: “They are all future technology professionals who are going to make all of us proud.” I guess I have a lot of things to learn. Hats off to Allen!
