  • SQL Server Migration Assistant 2008 (SSMA)

    One of my client’s requirements is to migrate and consolidate his company departments’ databases to SQL Server 2008. As I know the environment, they are using MySQL , MS-Access and SQL Server with different applications. Now the company has decided to have a single dedicated SQL Server 2008 database server to host all the applications. So there are a few things to do to upgrade and migrate from MySQL and MS-Access to SQL Server 2008. For the migration task, I found the SQL Server Migration Assistant 2008 (SSMA 2008) is very useful which reduces the effort and risk of migration. So in this tip, I will do an overview of SSMA 2008.

  • Does it matter that the TTL is higher than I've been told?

    - by Andy
    Ok, so the title isn't very descriptive, I know. Basically, I'm trying to configure Outlook.com to use my custom domain! I've followed the steps and made the account etc. and now I have the DNS settings to configure from Windows Live. I added the MX Entries and everything last night but Windows Live is still saying I need to prove my ownership of the domain. The only thing I can think of that I had to use a differrent TTL to the one provided because my web hoster will only allow a minimum of four hours, whereas Windows Live told me to configure the TTL as one hour. Would that stop anything? By the way, my web hoster is JustHost (Shared Hosting)

  • Try/Catch or test parameters

    - by Ondra Morský
    I was recently on a job interview and I was given a task to write simple method in C# to calculate when the trains meet. The code was simple mathematical equation. What I did was that I checked all the parameters on the beginning of the method to make sure, that the code will not fail. My question is: Is it better to check the parameters, or use try/catch? Here are my thoughts: Try/catch is shorter Try/catch will work always even if you forget about some condition Catch is slow in .NET Testing parameters is probably cleaner code (Exceptions should be exceptional) Testing parameters gives you more control over return values I would prefer testing parameters in methods longer than +/- 10 lines, but what do you think about using try/catch in simple methods just like this – i.e. return (a*b)/(c+d); There are many similar questions on stackexchnage, but I am interested in this particular scenario.

  • Best strategy for supporting multiple server communication from iPhone/android app?

    - by tipycalFlow
    I'm making an app that will be used in multiple hospitals in the US. As per HIPAA compliance requirement, every hospital will have its own server that complies with these requirements of ensuring patient data security, etc. Now the task is that the app should communicate with a particular server based on the login info. An additional requirement is that new hospitals(servers) are likely to be added along the way, even after the app is available on the market. So basically, according to some login credentials, the app should communicate with the server of the hospital assigned to that person. One pretty crude way is to set up our own server which links the hospitals with the login info and accordingly, provides a base-url for data exchange. Is there a more efficient way to handle this?

  • Help with timebased scoring algorithm

    - by Dave
    Im trying to devise an appropriate scoring system for my game. The game in essense has a finite number of tasks to complete (say 20) and the quicker you complete these task, the more points you get. I had devised a basic way of doing this using bands of time multiplied by a score for that band multiplied by the number of tasks solved within that time band i.e. (Time Band) = (Points) 1-5 sec = 15, 5-10 secs = 10, 10-20 secs = 5, 20-30 secs = 3, 40 secs onwards = 1, So for example if I did 3 tasks in the 1-5sec band i'd get 15*3=45points, if i found 10 in the 20-30sec band i'd get 3*10=30 points. Im sure there is a more mathematical way of doing this using powers of some kind but I just can't think how and hoping someone has already done something smilar.. Many thanks in advance

  • What are some methods for pulling information and interacting with flash games?

    - by Xploit
    In general, how should I approach interacting with a flash game pragmatically? The flash game is online and I would like to be able to pull information from the game, make computations, and send the appropriate keystrokes back to the flash game? I'm having difficult deciding how to begin. Any specific libraries or languages that you feel would be best for accomplishing this task? I would like it to be as fast as possible. Are there ways of doing this without taking screen shots and simulating keyboard presses?

  • How to make Nautilus name column display at the width of the longest filename

    - by fred.bear
    Prior to a recent glytch where I lost some of my custom settings, Nautilus would open directories and display the name-column wide enough to show the longest filename on display. It did it dynamically; If I renamed a file to a longer or shorter name, the column was automatically adjusted to the new width.. It's not doing that now, and I have no idea how to get this function back.. UPDATE I hadn't mentioned it, but I am talking about the List view... I have been fossicing around in the GConf Editpr and came across a setting for Compact View which does exactly what I am referring to... but it only effects the Compact View... that setting is: gconf-editor /apps/nautilus/compact_view/all_columns_have_same_width ...but I can't find the setting for List View... I know the capability exists, because I've been using it until only a few days ago, when my system got hung up...

  • rotate opengl mesh relative to camera

    - by shuall
    I have a cube in opengl. It's position is determined by multiplying it's specific model matrix, the view matrix, and the projection matrix and then passing that to the shader as per this tutorial (http://www.opengl-tutorial.org/beginners-tutorials/tutorial-3-matrices/). I want to rotate it relative to the camera. The only way I can think of getting the correct axis is by multiplying the inverse of the model matrix (because that's where all the previous rotations and tranforms are stored) times the view matrix times the axis of rotation (x or y). I feel like there's got to be a better way to do this like use something other than model, view and projection matrices, or maybe I'm doing something wrong. That's what all the tutorials I've seen use. PS I'm also trying to keep with opengl 4 core stuff. edit: If quaternions would fix my problems, could someone point me to a good tutorial/example for switching from 4x4 matrices to quaternions. I'm a little daunted by the task.

  • How can I designed multi-threaded application for larger user base

    - by rokonoid
    Here's my scenario, I need to develop a scalable application. My user base may be over 100K, every user has 10 or more small tasks. Tasks check every minute with a third party application through web services, retrieving data which is written in the database, then the data is forwarded to it's original destination. So here's the processing of a small task: while(true){ Boolean isNewInformationAvailable = checkWhetherInformationIsAvailableOrNot(); If(isNewInformationAvailable ==true){ fetchTheData(); writeToDatabase(); findTheDestination(); deliverTheData(); isAvailable =false; } } Here is the question: as the application is large, how should I approach designing this. I'm going to use Java to write it. Should I use concurrency, and how would you manage the concurrency?

  • AntClassLoader bug exposed by forgetful NetBeans

    - by vbkraemer
    Many users have run into ClassNotFoundExceptions and NoClassDefFoundErrors after working with web services that target GlassFish while developing their projects in NetBeans. The issue usually appears as a dialog similar to this This can be pretty debilitating. The bug appears to be in the AntClassLoader, which is tickled by the wsimport ant task that ships with GlassFish 3.1.2. The fix is pretty simple: Upgrade the Metro bits that ship in 3.1.2 with bits that have had a patch applied. There are detailed instruction about installing the updated Metro bits onto GlassFish. This upgrade is probably useful for any install of GlassFish 3.1, but it is critically important for folks that develop web services from inside NetBeans and deploy them onto GlassFish 3.1.2.

  • How to prioritize tasks when you have multiple programming projects running in parallel?

    - by Vinko Vrsalovic
    Say you have 5 customers, you develop 2 or 3 different projects for each. Each project has Xi tasks. Each project takes from 2 to 10 man weeks. Given that there are few resources, it is desired to minimize the management overhead. Two questions in this scenario: What tools would you use to prioritize the tasks and track their completion, while tending to minimize the overhead? What criteria would you take into consideration to determine which task to assign to the next available resource given that the primary objective is to increase throughput (more projects finished per time unit, this objective conflicts with starting one project and finishing it and then moving on to the next)? Ideas, management techniques, algorithms are welcome

  • Are these interview questions too difficult for entry-level C++ positions?

    - by Banana
    I recently had a few interviews for programming jobs within the financial industry. I am looking for entry-level positions as I specify in the cover letter. However I am usually asked questions such as: - all two-letters commands you know in unix - representation of float/double numbers (ieee standard) - segmentation fault memory dump, and related issues - all functions you know to convert string to integer (not just atoi) - how to avoid virtual tables - etc.. Is that the custom? Because I don't think this kind of questions make sense for someone willing to get an entry-level job. Is it totally crazy to think that they should ask more conceptual questions? This is beginning to driving me nuts, honestly. Thanks

  • How to remove text from file icons ?

    - by Jesse
    I am fairly new to Ubuntu (Linux). I noticed when creating a .java file or .py gives me an icon, however when I start writing code it overrides the thumbnail into showing text. Is there a way to disable this silly feature ? When I installed Linux Mint on the VM I noticed I was able to accomplish this task by unchecking "Show text in icon". I know they use Namo as their file manager. I read this thread and it did not work. How to stop Nautilus from creating thumbnails of specific file types?

  • How can i distinguish revenue from different folders in Adsense?

    - by tarrasch
    I am currently running three websites using adsense. Since i do this more to be useful than to earn something, i have a subdomain of a free hoster and my websites live in subfolders e.q. mydomain.hoster.com/website1, mydomain.hoster.com/website2, to which i link with .tk aliases. Is there a way to distinguish adsense income from website1 to website 2? I tried using custom channels, but somehow this part of adsense eludes me. Can someone shed some light on this?

  • How can I programmatically block user input for a given time?

    - by black_puppydog
    As a person working in computer science working offline to avoid facebook and thelike is not always (meaning hardly ever) possible for me since I mostly have to be online to work. I have tried leechblock and similar things but the problem becomes that at some point I start making systems for myself to hack, which is kind of pointless if oyu have root. I would very much like to try out the method described here. (Short version: reboot your PC every time finish a task or get bored with it) Unlike for the author of this blog my work is mainly done not in screen sessions but in IDEs ans other not-so-fast-to-start-up stuff, meaning a full reboot including loading all my programs will take its time. So, the question is: How can I block all user input and preferrably blank the screen for a given amount of time? The idea would then be to have a keyboard shortcut to activate the script/program (which would probably also have to have root i guess?)

  • Game Server on Windows Azure

    - by MrWiggels
    What do you guys think of using Windows Azure for deploying a custom built game server. It's being built in C#, and I want to get a few things down before stretching too far into the project. I like the idea of being scalable, but I also know that I will never get to the scale of anything to the scale of WOW, or something quite as big. It will just be an interesting journey to test something like this. So, will Windows Azure work for that, or is there any other services that can provide something like that?

  • desktop problems in 12.04

    - by joe
    I recently upgraded from 11.10 (i think that was the last version that was out) to 12.04 and ever since i have been unable to start my computer (hp pavillion dv2815nr) in the "normal" mode, but have had to start it using previous versions. Every time I go to start it, it has a plain red screen (which it does in the previous versions as well) and the desktop icons will not respond. Also, the task bar at top is essentially missing, only having a thin black line there, and also missing the icon bar that "pops out" when you scroll along the left side of the screen. Essentially, I'm locked out in normal mode. Nothing will respond.

  • Getting Started with ADF Mobile Sample Apps

    - by Denis T
    Getting Started with ADF Mobile Sample Apps   Installation Steps Install JDeveloper 11.1.2.3.0 from Oracle Technology Network After installing JDeveloper, go to Help menu and select "Check For Updates" and find the ADF Mobile extension and install this. It will require you restart JDeveloper For iOS development, be on a Mac and have Xcode installed. (Currently only Xcode 4.4 is officially supported. Xcode 4.5 support is coming soon) For Android development, have the Android SDK installed. In the JDeveloper Tools menu, select "Preferences". In the Preferences dialog, select ADF Mobile. You can expand it to select configure your Platform preferences for things like the location of Xcode and the Android SDK. In your /jdeveloper/jdev/extensions/oracle.adf.mobile/Samples folder you will find a PublicSamples.zip. Unzip this into the Samples folder so you have all the projects ready to go. Open each of the sample application's .JWS file to open the corresponding workspace. Then from the "Application" menu, select "Deploy" and then select the deployment profile for the platform you wish to deploy to. Try deploying to the simulator/emulator on each platform first because it won't require signing. Note: If you wish to deploy to the Android emulator, it must be running before you start the deployment.   Sample Application Details   Recommended Order of Use Application Name Description 1 HelloWorld The "hello world" application for ADF Mobile, which demonstrates the basic structure of the framework. This basic application has a single application feature that is implemented with a local HTML file. Use this application to ascertain that the development environment is set up correctly to compile and deploy an application. See also Section 4.2.2, "What Happens When You Create an ADF Mobile Application." 2 CompGallery This application is meant to be a runtime application and not necessarily to review the code, though that is available. It serves as an introduction to the ADF Mobile AMX UI components by demonstrating all of these components. Using this application, you can change the attributes of these components at runtime and see the effects of those changes in real time without recompiling and redeploying the application after each change. See generally Chapter 8, "Creating ADF Mobile AMX User Interface." 3 LayoutDemo This application demonstrates the user interface layout and shows how to create the various list and button styles that are commonly used in mobile applications. It also demonstrates how to create the action sheet style of a popup component and how to use various chart and gauge components. See Section 8.3, "Creating and Using UI Components" and Section 8.5, "Providing Data Visualization." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 4 JavaDemo This application demonstrates how to bind the user interface to Java beans. It also demonstrates how to invoke EL bindings from the Java layer using the supplied utility classes. See also Section 8.10, "Using Event Listeners" and Section 9.2, "Understanding EL Support." 5 Navigation This application demonstrates the various navigation techniques in ADF Mobile, including bounded task flows and routers. It also demonstrates the various page transitions. See also Section 7.2, "Creating Task Flows." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 6 LifecycleEvents This application implements lifecycle event handlers on the ADF Mobile application itself and its embedded application features. This application shows you where to insert code to enable the applications to perform their own logic at certain points in the lifecycle. See also Section 5.6, "About Lifecycle Event Listeners." Note: iOS, the LifecycleEvents sample application logs data to the Console application, located at Applications-Utilities-Console application. 7 DeviceDemo This application shows you how to use the DeviceFeatures data control to expose such device features as geolocation, e-mail, SMS, and contacts, as well as how to query the device for its properties. See also Section 9.5, "Using the DeviceFeatures Data Control." Note: You must also run this application on an actual device because SMS and some of the device properties do not function on an iOS simulator or Android emulator. 8 GestureDemo This application demonstrates how gestures can be implemented and used in ADF Mobile applications. See also Section 8.4, "Enabling Gestures." 9 StockTracker This application demonstrates how data change events use Java to enable data changes to be reflected in the user interface. It also has a variety of layout use cases, gestures and basic mobile patterns. See also Section 9.7, "Data Change Events."

  • Combining a content management system with ASP.NET

    - by Ek0nomik
    I am going to be creating a site that seems like it requires a blend of a content management system (CMS) and some custom web development (which is done in ASP.NET MVC). I have plenty of web development experience to understand the ASP.NET MVC side of the fence, but, I don't have a lot of CMS knowledge aside from getting one stood up. Right now my biggest question is around integrating security from ASP.NET with the CMS. I currently have an ASP.NET MVC site that handles the authentication for multiple production sites and creates an authentication cookie under our domain (*.example.com). The page acts like a single sign on page since the cookie is a wildcard and can be used in any other applications of the same domain. I'd really like to avoid having users put in their credentials twice. Is there a CMS that will play well with the ASP.NET Forms Authentication given how I have these existing applications structured? As an aside, right now I am leaning towards Drupal, but, that isn't finalized.

  • How can I make refactoring a priority for my team?

    - by Joseph Garland
    The codebase I work with daily has no automated tests, inconsistent naming and tons of comments like "Why is this here?", "Not sure if this is needed" or "This method isn't named right" and the code is littered with "Changelogs" despite the fact we use source control. Suffice it to say, our codebase could use refactoring. We always have tasks to fix bugs or add new features, so no time is put aside to refactor code to be better and more modular, and it doesn't seem to be a high priority. How can I demonstrate the value of refactoring such that it gets added to our task lists? Is it worth it to just refactor as I go, asking for forgiveness rather than permission?

  • Certain Keyboard shortcuts not working

    - by user968808
    I have the logitech k800 keyboard but can't seem to get certain shortcuts working. I change in the keyboard shortcut settings volume up and down and it actually takes the key assignment but does not take effect when trying to use. After trying for a while I also tried to create a custom shortcut after with the command amixer -q sset Master 10%- Finally I tried changing the command to touch a file to see if it is actually responding but nothing. How can it take the key as an assignment in the shortcut settings but not to actually respond when pressing it. FYI other keys work like mute, next track etc. There is just 3 keys shortcuts not currently working. Thanks
