• Regular Expression Transformation

  The regular expression transformation exposes the power of regular expression matching within the pipeline. One or more columns can be selected, and for each column an individual expression can be applied. The way multiple columns are handled can be set on the options page. The AND option means all columns must match, whilst the OR option means only one column has to match. If rows pass their tests then rows are passed down the successful match output. Rows that fail are directed down the alternate output. This transformation is ideal for validating data through the use of regular expressions. You can enter any expression you like, or select a pre-configured expression within the editor. You can expand the list of pre-configured expressions yourself. These are stored in a Xml file, %ProgramFiles%\Microsoft SQL Server\nnn\DTS\PipelineComponents\RegExTransform.xml, where nnn represents the folder version, 90 for 2005, 100 for 2008 and 110 for 2012. If you want to use regular expressions to manipulate data, rather than just validating it, try the RegexClean Transformation. The component is provided as an MSI file, however for 2005/200 you will have to add the transformation to the Visual Studio toolbox by hand. This process has been described in detail in the related FAQ entry for How do I install a task or transform component?, just select Regular Expression Transformation in the Choose Toolbox Items window. Downloads The Regular Expression Transformation is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed.

• Best practice while marking a bug as resolved with Bugzilla (versioning of product and components)

  - by Vincent B.

  I am wondering what is the best way to handle the situation of marking a bug as resolved and providing a version of component/product in which this fix can be found. Context For a project I am working on, we are using Bugzilla for issue tracking, and we have the following: A product "A" with a version number like vA.B.C.D, This product "A" have the following components: Component "C1" with a version number like vA.B.C.D, Component "C2" with a version number like vA.B.C.D, Component "C3" with a version number like vA.B.C.D. Internally we keep track of which component versions have been used to generate the product A version vA.B.C.D. Example: Product "A" version v1.0.0.0 has been produced from component "C1" v1.0.0.3, component "C2" v1.3.0.0 and component "C3" v2.1.3.5. And Product "A" version v1.0.1.0 has been produced from component "C1" v1.0.0.4, component "C2" v1.3.0.0 and component "C3" v2.1.3.5. Each component is a SVN repository. The person in charge of generating the product "A" have only access to the different components tags folder in SVN, and not the trunk of each component repository. Problem Now the problem is the following, when a bug is found in the product "A", and that the bug is related to Component "C1", the version of product "A" is chosen (e.g. v1.0.0.0), and this version allow the developer to know which version of component "C1" has the bug (here it will be v1.0.0.3). A bug report is created. Now let's say that the developer responsible for component "C1" corrects the bug, then when the bug seems to be fixed and after some test and validation, the developer generates a new tag for component "C1", with the version v1.0.0.4. At this time, the developer of component "C1" needs to update the bug report, but what is the best to do: Mark the bug as resolved/fixed and add a comment saying "This bug has been fixed in the tags v1.0.0.4 of C1 component" ? Keep the bug as assigned, add a comment saying "This bug has been fixed in the tags v1.0.0.4 of C1 component, update this bug status to resolved for the next version of the product that will be generated with the newest version (v1.0.0.4 of C1)" ? Another possible way to deal with this problem. Right now the problem is that when a product component CX is fixed, it is not sure in which future version of the product A it will be included, so it is for me not possible to say in which version of the product it will be solved, but it is possible to say in which version of the Component CX it has been solved. So when do we need to mark a bug as solved, when the product A version include the fixed version of CX, or only when CX component has been fixed ? Thanks for your personal feedback and ideas about this !

• Taking a screenshot from within a Silverlight #WP7 application

  - by Laurent Bugnion

  Often times, you want to take a screenshot of an application’s page. There can be multiple reasons. For instance, you can use this to provide an easy feedback method to beta testers. I find this super invaluable when working on integration of design in an app, and the user can take quick screenshots, attach them to an email and send them to me directly from the Windows Phone device. However, the same mechanism can also be used to provide screenshots are a feature of the app, for example if the user wants to save the current status of his application, etc. Caveats Note the following: The code requires an XNA library to save the picture to the media library. To have this, follow the steps: In your application (or class library), add a reference to Microsoft.Xna.Framework. In your code, add a “using” statement to Microsoft.Xna.Framework.Media. In the Properties folder, open WMAppManifest.xml and add the following capability: ID_CAP_MEDIALIB. The method call will fail with an exception if the device is connected to the Zune application on the PC. To avoid this, either disconnect the device when testing, or end the Zune application on the PC. While the method call will not fail on the emulator, there is no way to access the media library, so it is pretty much useless on this platform. This method only prints Silverlight elements to the output image. Other elements (such as a WebBrowser control’s content for instance) will output a black rectangle. The code public static void SaveToMediaLibrary( FrameworkElement element, string title) { try { var bmp = new WriteableBitmap(element, null); var ms = new MemoryStream(); bmp.SaveJpeg( ms, (int)element.ActualWidth, (int)element.ActualHeight, 0, 100); ms.Seek(0, SeekOrigin.Begin); var lib = new MediaLibrary(); var filePath = string.Format(title + ".jpg"); lib.SavePicture(filePath, ms); MessageBox.Show( "Saved in your media library!", "Done", MessageBoxButton.OK); } catch { MessageBox.Show( "There was an error. Please disconnect your phone from the computer before saving.", "Cannot save", MessageBoxButton.OK); } } This method can save any FrameworkElement. Typically I use it to save a whole page, but you can pass any other element to it. On line 7, we create a new WriteableBitmap. This excellent class can render a visual tree into a bitmap. Note that for even more features, you can use the great WriteableBitmapEx class library (which is open source). On lines 9 to 16, we save the WriteableBitmap to a MemoryStream. The only format supported by default is JPEG, however it is possible to convert to other formats with the ImageTools library (also open source). Lines 18 to 20 save the picture to the Windows Phone device’s media library. Using the image To retrieve the image, simply launch the Pictures library on the phone. The image will be in Saved Pictures. From here, you can share the image (by email, for instance), or synchronize it with the PC using the Zune software. Saving to other platforms It is of course possible to save to other platforms than the media library. For example, you can send the image to a web service, or save it to the isolated storage on the device. To do this, instead of using a MemoryStream, you can use any other stream (such as a web request stream, or a file stream) and save to that instead. Hopefully this code will be helpful to you! Happy coding, Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Library to fake intermittent failures according to tester-defined policy?

  - by crosstalk

  I'm looking for a library that I can use to help mock a program component that works only intermittently - usually, it works fine, but sometimes it fails. For example, suppose I need to read data from a file, and my program has to avoid crashing or hanging when a read fails due to a disk head crash. I'd like to model that by having a mock data reader function that returns mock data 90% of the time, but hangs or returns garbage otherwise. Or, if I'm stress-testing my full program, I could turn on debugging code in my real data reader module to make it return real data 90% of the time and hang otherwise. Now, obviously, in this particular example I could just code up my mock manually to test against a random() routine. However, I was looking for a system that allows implementing any failure policy I want, including: Fail randomly 10% of the time Succeed 10 times, fail 4 times, repeat Fail semi-randomly, such that one failure tends to be followed by a burst of more failures Any policy the tester wants to define Furthermore, I'd like to be able to change the failure policy at runtime, using either code internal to the program under test, or external knobs or switches (though the latter can be implemented with the former). In pig-Java, I'd envision a FailureFaker interface like so: interface FailureFaker { /** Return true if and only if the mocked operation succeeded. Implementors should override this method with versions consistent with their failure policy. */ public boolean attempt(); } And each failure policy would be a class implementing FailureFaker; for example there would be a PatternFailureFaker that would succeed N times, then fail M times, then repeat, and a AlwaysFailFailureFaker that I'd use temporarily when I need to simulate, say, someone removing the external hard drive my data was on. The policy could then be used (and changed) in my mock object code like so: class MyMockComponent { FailureFaker faker; public void doSomething() { if (faker.attempt()) { // ... } else { throw new RuntimeException(); } } void setFailurePolicy (FailureFaker policy) { this.faker = policy; } } Now, this seems like something that would be part of a mocking library, so I wouldn't be surprised if it's been done before. (In fact, I got the idea from Steve Maguire's Writing Solid Code, where he discusses this exact idea on pages 228-231, saying that such facilities were common in Microsoft code of that early-90's era.) However, I'm only familiar with EasyMock and jMockit for Java, and neither AFAIK have this function, or something similar with different syntax. Hence, the question: Do such libraries as I've described above exist? If they do, where have you found them useful? If you haven't found them useful, why not?

• SharePoint 2010 Hosting :: Sending SMS Alerts in SharePoint 2010 Over Office Mobile Service Protocol (OMS)

  - by mbridge

  In this post, I want to share the exciting news of SharePoint's 2010 new feature. Finally it's possible to send SMS directly from SharePoint to mobile phones. The advantages of sending SMS instead of Email messages are obvious: SMS alerts or reminders that are received on mobile phones are more preferred than Email messages that can be lost in the mass of spam. The interface is standard as it's very similar to previous versions of the product. Adjustments are easy to do, simply enter the address of the Office Mobile Service (OMS) web-service which you want to use for sending messages, then specify the connection parameters. Further details on Office Mobile Service is available below. The Test Service button checks if OMS web-service is accessible using provided URL (user name and password are not verified). This check is needed because OMS web-service URL depends on the mobile operator and country. It's now possible to select the method of sending alerts in alerts settings. Email option is selected by default. Alerts delivery method is displayed in the list of existing alerts. Office Mobile Service (OMS) SharePoint 2010 uses exterior servers similar to SMTP servers for sending SMS alerts. However, Microsoft started development and promotion of their own protocol instead of using existing ones. That is how Office Mobile Service (OMS) appeared. This open protocol enables clients to send text and multimedia messages (mobile messages) remotely to the server which processes these messages and delivers them to mobile phones.  Typical scenario of utilizing this protocol is data transfer between computer application and mobile phone. The recipient can answer messages and the server in return will deliver the answer by SMTP protocol, i.e. by email.  Key quality of this protocol is that it's built on base of HTPP(S) and SOAP protocols.     This means that in fact SMS gateway must support typified web-service. What do you get from web-service? What you get is the ability to send SMS from any platform you want.  The protocol is being developed at the moment and version 0.2 from 08/28/2009 was available when the article was published.  For promotion of their protocol and simplifying server search, Microsoft represented web-service http://messaging.office.microsoft.com/HostingProviders.aspx that helps to receive the list of providers, which supports OMS protocol and message delivery to your operator.  All you need to do is decide which provider to use, complete the agreement, then adjust the SharePoint connection parameters and start working.  Some providers advertise themselves not only for clients but for mobile operators as well. They offer automatic adding to the list of the Office Mobile Service Providers.  To view the full specifications of OMS, please go to http://msdn.microsoft.com/en-us/library/dd774103.aspx.

• Managing Joomla via Android

  Surprisingly, it was only today that I actually looked for possible solutions to write more content for my blog. Since quite some time I'm using my Samsung Galaxy Tab 10.1 for all kind of social media activities like Google+, FB, etc. but also for my casual mail during the evening hours. And yes, I feel a little bit guilty about missing the chance to use my tablet to write some content here... OK, only a little bit. ;-) These are not the droids you are looking for But those lazy times are over! While searching the Play Store with the expression 'joomla' I got three interesting hits: - Joomla Admin Mobile! - Joooid - Joomla! Security Checklist After reading the reviews I installed the two later apps. Joomla! Security Checklist The author clearly outlines here that the app is primarily for his personal purpose to have safety checklist at hand at anytime. I guess that any reader of this article has an Android based smartphone or tablet, so that simple app should be part of your toolbox when using Joomla! for your websites. Joooid plugin & app Although I was looking for an app that could work with the default XML RPC interface of Joomla I have to admit that this combination of an enhanced Web service suits me better, mainly due to performance reason. The official website has not only the downloads for Joomla versions 1.5 - 2.5 but also very good and easy to follow step-by-step instructions to prepare your server for the Android app. It will take you less than 5 minutes to get it up and running. For safety reasons, I recommend that you should configure your Web server to have an additional authentication layer on the plugins folder. The smartphone app has the ability to run against HTTP authentication. Personally, I like the look and feel of the app. It is a little bit different compared to the web UI but still easy to use. In fact, this article is the first one written in the Joooid app. At the moment, I only miss the ability to have list tags. Quick and easy Writing full-fledged articles with images, a couple of hyperlinks and some styling here and there should be left to the desktop. At least for the moment. Let's see whether I'm going to change my mind on this during the upcoming months... I'll give it a try, and hope to publish at least once per month to write some content using Joooid. Actually, it would be great to have some feedback about other Joomla! clients in the wild.

• Cloud Backup: Getting the Users' Backs Up

  - by Tony Davis

  On Wednesday last week, Microsoft announced that as of July 1, all data transfers into its Microsoft Azure cloud will be free (though you have to pay for transferring data out). On Thursday last week, SQL Azure in Western Europe went down. It was a relatively short outage, but since SQL Azure currently provides no easy way to take a standard backup of a database and store it locally, many people had no recourse but to wait patiently for their cloud-based app to resume. It seems that Microsoft are very keen encourage developers to move their data onto their cloud, but are developers ready to do it, given that such basic backup capabilities are lacking? Recently on Simple-Talk, Mike Mooney described a perfect use case for the Microsoft Cloud. They had a simple web-based application with a SQL Server backend; they could move the application to Windows Azure, and the data into SQL Azure and in the process free themselves from much of the hassle surrounding management and scaling of the hardware, network and so on. It was a great fit and yet it nearly didn't happen; lack of support for the BACKUP command almost proved a show-stopper. Of course, backups of Azure databases are always and have always been taken automatically, for disaster recovery purposes, but these are strictly on-cloud copies and as of now it is not possible to use them to them to restore a database to a particular point in time. It seems that none of those clever Microsoft people managed to predict the need to perform basic backups of Azure databases so that copies could be stored locally, outside the Azure universe. At the very least, as Mike points out, performing a local backup before a new deployment is more or less mandatory. Microsoft did at least note the sound of gnashing teeth and, as a stop-gap measure, offered SQL Azure Database Copy which basically allows you to create an online clone of your database, but this doesn't allow for storing local archives of the data. To that end MS has provided SQL Azure Import/Export, to package up and export a database and its data, using BACPACs. These BACPACs do not guarantee transactional consistency; for example, if a child table is modified after the parent is copied, then the copied database will be in inconsistent state (meaning, to add to the fun, BACPACs need to be created from a database copy). In any event, widespread problems with BACPAC's evil cousin, the DACPAC have been well-documented, and it seems likely that many will also give BACPAC the bum's rush. Finally, in a TechEd 2011 presentation tagged "SQL Azure Advanced Administration", it was announced that "backup and restore" were coming in the next SQL Azure CTP. And yet this still doesn't mean that we'll get simple backups as DBAs know and love them. What it does mean, at least, is the ability to restore any given database to a point in time within a 2-week window. For the time being, if you want a local copy of your data and don't want to brave the BACPAC, one is left with SSIS or BCP, creative use of schema and data comparison tools, or use of SQL Azure Backup (currently in beta) in order to perform this simple but vital task. Cheers, Tony.

• Are there any drawbacks to the Major.Minor.YMDD.Build version strategy?

  - by Chu

  I'm trying to come up with a good version strategy to fit our specific needs. We've proposed settling on this and I wanted to ask the question to see if anyone's experience would suggest avoiding this or altering it in any way. Here's our proposal: Versions are released in this format: MAJOR.MINOR.YMDD.BN. Here it is broken out: MAJOR & MINOR are typical; we'll increase MINOR when we feel code and new feature sets warrants it; once every few months most likely. MAJOR will increase ~yearly. YMDD: Y will be the last digit of the current year, so "1" for 2011, "2" for 2012, etc. A non-padded month will be used to keep the number smaller (9 instead of 09 for example). DD of course is the day, padded with a zero for days under 10. BN: BN is the build number and increases by one anytime we make a change to a branch of the code represented by the build, for example: If were to make a build today, our release would be version 5.0.1707.1. I release to QA today and 3 days from now QA finds that a change broke the save functionality on a page. Instead of me changing our current development code, I'd go back to the code that I used to create version 5.0.1707.1, make the fix there, then increase the BN portion of the version and would then re-release 5.0.1707.2 back to QA. In short, anytime a change is made to a branched version that isn't the active dev branch, we'd use the original version number and increase only the BN portion (even if the change happened 3 days, 3 weeks or 3 months from the initial release of that version). Anytime we make a new release from our Active dev branch, we'd come up with a new version based on the M/D of the release using the outlined strategy. We do this once every 2-3 weeks. Are there holes or pitfalls with this? If so, what are they? Thanks EDIT To clarify one point that I didn't get out very well - Oct/Nov/Dec will be two digits, it's only the year that won't be. So 9 for Sept, 10 for Oct, 11 for Nov, etc.

• Disneyland Inside Out on iPhone and Android

  - by Ryan Cain

  It's hard to believe October was the last time I was over here on my blog.  Ironically after getter the developer phone from Microsoft I have been knee deep in iPhone programming and for the past few weeks Android programming again.  This time I've spent all my non-working hours programming a fun project for my "other" website, Disneyland Inside Out.  Disneyland Inside Out, a vacation planning site for Disneyland in California, has been around in various forms since June 1996.  It has always been a place for me to explore new technologies and learn about some of the new trends on the web.  I recently migrated the site over to DotNetNuke and have been building out custom modules for DNN.  I've also been hacking things together w/ the URLRewrite module in IIS 7.5 to provide strong SEO optimized URLs.  I can't say all that has really stuck within the DNN model of doing things, but it has worked pretty well. As part of my learning process, I spent most of the Fall bringing Disneyland Inside Out to the iPhone.  I will post more details on my development experiences later.  But this project gave me a really great opportunity to get a good feel for Objective-C development.  After 3 months I actually feel somewhat competent in the language and iPhone SDK, instead of just floundering around getting things to work.  The project also gave me a chance to play with some new frameworks on the iPhone and really dig into the Facebook SDK.  I also dug into some of the Gowalla REST api's as well.  We've been live with the app in iTunes for just about 10 days now, and have been sitting in the top 200 of free travel apps for the past few days.  You can get more info and the direct iTunes download link on our site: Disneyland Inside Out for iPhone Since launching the iPhone version I have gotten back into Android development, porting the Disneyland Inside Out app over to Android.  As I said in my first review of iPhone vs. Android, coming from a managed code background, Android is much easier to get going with.  I just about 3 weeks total I will have about 85 - 90% of the functionality up and running in the Android app, that took probably 1.5 - 2x's that time for iPhone.  That isn't a totally fair comparison as I am much more comfortable w/ Xcode and Objective-C today and can get some of the basic stuff done much faster than I could in the fall.  Though I'd say some of the hardest code to debug is still the null pointer issues on objects that were dealloc'd too early in Objective-C.  This isn't too bad with the NSZoombies enabled for synchronous code, but when you have a lot of async, which my app does, it can be hairy at times to track exactly what was causing the issue.   I will post more details later, as I am trying to wrap up a beta of the Android app today.  But in the meantime, if you have an iPhone, iPod Touch or iPad head on over to the site and take a look at my app.

• questions about dual-boot install Ubuntu 10.04 and Windows 7 on same hard drive

  - by Tim

  I'd like to dual-boot install Ubuntu 10.04 on the same hard drive as Windows 7 which has already been installed. As to sources on the internet: I found a website iinet about dual-boot installation of Ubuntu 10.10 and Windows 7 on the same hard drive, which I think more specific than the one on Ubuntu Community without specific version of the OSes. Since I am installing Ubuntu 10.04 instead of 10.10, my question is whether their installers are same or almost same and if I can follow iinet for my dual-boot installation? Or are there better websites for information about dual-boot installtion of Ubuntu 10.04 and Windows 7? As to shrinking Windows partitions to make free space for Ubuntu partitions: iinet uses the partition software in Ubuntu's installer to shrink the Windows partition. But I saw in many website that the partition software in Ubuntu's installer cannot guarantee shrinking Windows 7 partitions successfully, so they recommended in general to shrink Windows partitions under Windows itself using its softwares. For example, in Ubuntu Community, it says: Some people think that the Windows partition must be resized only from within Windows Vista and Windows 7 using the shrink/resize option. ... If you use GParted Partition Editor in the Ubuntu Live CD be careful. So I was wondering which way to go in my situation? As to partition for bootloader files: In iinet, I don't see there is a partition created and dedicated to boot files (i.e. Grub files). However, I saw in many websites strongly suggesting using a boot partition for Grub files, especially for the purpose of separation and protection from installed OS files. I was wondering which way I should choose and why? As to installing bootloader Grub, in iinet, I see that to install Grub it only needs to specify the hard drive device for bootloader installation. However, in ubuntuguide(for more than 2 OSes and Ubuntu 9.04), some commands are needed to run in order to put Grub configuration files in MBR, and OS partition, for the chain-load process (where to find the files for the next stage). In Ubuntu Community, there are some related sentences which I don't quite understand how to do in practice: the only thing in your computer outside of Ubuntu that needs to be changed is a small code in the MBR (Master Boot Record) of the first hard disk. The MBR code is changed to point to the boot loader in Ubuntu. If you have a problem with changing the MBR code, you might prefer to just install the code for pointing to GRUB to the first sector of your Ubuntu partition instead. If you do that during the Ubuntu installation process, then Ubuntu won't boot until you configure some other boot manager to point to Ubuntu's boot sector. Windows Vista no longer utilizes boot.ini, ntdetect.com, and ntldr when booting. Instead, Vista stores all data for its new boot manager in a boot folder. Windows Vista ships with an command line utility called bcdedit.exe, which requires administrator credentials to use. You may want to read http://go.microsoft.com/fwlink/?LinkId=112156 about it. Using a command line utility always has its learning curve, so a more productive and better job can be done with a free utility called EasyBCD, developed and mastered in during the times of Vista Beta already. EasyBCD is user friendly and many Vista users highly recommend EasyBCD. In what is quoted above, I was wondering how exactly I should change the MBR code to point to the bootloader in Ubuntu? if I fail to change MBR code, are the other suggested boot managers being bcdedit.exe and EasyBCD in Windows? With the three sources above, which one shall I follow? Thanks and regards

• Windows Azure SDK 1.3 addresses early adopter feedback

  - by Eric Nelson

  At the end of November 2010 we released a new version of the Windows Azure SDK which contains many new features driven by the great feedback of early adopters plus a shiny new portal. New Portal implemented in Silverlight: The new portal is implemented using Silverlight and replaces the (IMHO rather clunky) original HTML + JavaScript portal. It is 100% better although does still have a few bugs. Enjoy! P.S. You can if you wish still use the old portal:   New runtime functionality: The following functionality is now generally available through the Windows Azure SDK and Windows Azure Tools for Visual Studio and the new Windows Azure Management Portal: Elevated Privileges and Full IIS. You can now run a portion or all of your code in Web and Worker roles with elevated administrator privileges. The Web role now provides Full IIS functionality, which enables multiple IIS sites per Web role and the ability to install IIS modules. Remote Desktop functionality enables you to connect to a running instance of your application or service in order to monitor activity and troubleshoot common problems. Windows Server 2008 R2 Roles: Windows Azure now supports Windows Server 2008 R2 in its Web, worker and VM roles. This new support enables you to take advantage of the full range of Windows Server 2008 R2 features such as IIS 7.5, AppLocker, and enhanced command-line and automated management using PowerShell Version 2.0. New runtime functionality – in beta: Windows Azure Virtual Machine Role: Support for more types of new and existing Windows applications will soon be available with the introduction of the Virtual Machine (VM) role. You can move more existing applications to Windows Azure, reducing the need to make costly code or deployment changes. Extra Small Windows Azure Instance, which is priced at $0.05 per compute hour, provides developers with a cost-effective training and development environment. Developers can also use the Extra Small instance to prototype cloud solutions at a lower cost. Windows Azure Connect: (formerly Project Sydney), which enables a simple and easy-to-manage mechanism to set up IP-based network connectivity between on-premises and Windows Azure resources, is the first Windows Azure Virtual Network feature that we’re making available as a CTP. You can sign up for any of the betas via the Windows Azure Management Portal. Improved processes and simplified operations New portal! (see above) Access to new diagnostic information including the ability to click on a role to see role type, deployment time and last reboot time A new sign-up process that dramatically reduces the number of steps needed to sign up for Windows Azure. New scenario based Windows Azure Platform forums to help answer questions and share knowledge more efficiently. Multiple Service Administrators: Windows Azure now supports multiple Windows Live IDs to have administrator privileges on the same Windows Azure account. The objective is to make it easy for a team to work on the same Windows Azure account while using their individual Windows Live IDs.   Related Links Please also let us know through Microsoft Platform Ready if and when you intend to build an application using the Windows Azure Platform. Or indeed if you already have (Well done). You will get access to some great benefits if you do (more on that in a future post). It also really helps us better understand the demand out there which directly impacts how we will plan the next six months of activities around the Windows Azure Platform.

• Using multiple diagrams per model in Entity Framework 5.0

  - by nikolaosk

  I have downloaded .Net framework 4.5 and Visual Studio 2012 since it was released to MSDN subscribers on the 15th of August.For people that do not know about that yet please have a look at Jason Zander's excellent blog post .Since then I have been investigating the many new features that have been introduced in this release.In this post I will be looking into theIn order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 20120 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine. I have also installed in my machine SQL Server 2012 developer edition. I have also downloaded and installed AdventureWorksLT2012 database.You can download this database from the codeplex website.   Before I start showcasing the demo I want to say that I strongly believe that Entity Framework is maturing really fast and now at version 5.0 can be used as your data access layer in all your .Net projects.I have posted extensively about Entity Framework in my blog.Please find all the EF related posts here. In this demo I will show you how to split an entity model into multiple diagrams using the new enhanced EF designer. We will not build an application in this demo.Sometimes our model can become too large to edit or view.In earlier versions we could only have one diagram per EDMX file.In EF 5.0 we can split the model into more diagrams.1) Launch VS 2012. Express edition will work fine.2) Create a New Project. From the available templates choose a Web Forms application  3) Add a new item in your project, an ADO.Net Entity Data Model. I have named it AdventureWorksLT.edmx.Then we will create the model from the database and click Next.Create a new connection by specifying the SQL Server instance and the database name and click OK.Then click Next in the wizard.In the next screen of the wizard select all the tables from the database and hit Finish.4) It will take a while for our .edmx diagram to be created. When I select an Entity (e.g Customer) from my diagram and right click on it,a new option appears "Move to new Diagram".Make sure you have the Model Browser window open.Have a look at the picture below 5) When we do that a new diagram is created and our new Entity is moved there.Have a look at the picture below  6) We can also right-click and include the related entities. Have a look at the picture below. 7) When we do that the related entities are copied to the new diagram.Have a look at the picture below  8) Now we can cut (CTRL+X) the entities from Diagram2 and paste them back to Diagram1.9) Finally another great enhancement of the EF 5.0 designer is that you can change colors in the various entities that make up the model.Select the entities you want to change color, then in the Properties window choose the color of your choice. Have a look at the picture below. To recap we have demonstrated how to split your entity model in multiple diagrams which comes handy in EF models that have a large number of entities in them Hope it helps!!!!

• WPF Control Toolkits Comparison for LOB Apps

  In preparation for a new WPF project Ive been researching options for WPF Control toolkits.  While we want a lot of the benefits of WPF, the application is a fairly typical line of business application (LOB).  So were not focused on things like media and animations, but instead a simple, solid, intuitive, and modern user interface that allows for well architected separation of business logic and presentation layers. While WPF is mature, it hasnt lived the long life that Winforms has yet, so there is still a lot of room for third party and community control toolkits to fill the gaps between the controls that ship with the Framework.  There are two such gaps I was concerned about.  As this is an LOB app, we have needs for presenting lots of data and not surprisingly much of it is in grid format with the need for high performance, grouping, inline editing, aggregation, printing and exporting and things that weve been doing with LOB apps for a long time.  In addition we want a dashboard style for the UI in which the user can rearrange and shrink and grow tiles that house the content and functionality.  From a cost perspective, building these types of well performing controls from scratch doesnt make sense.  So I evaluated what you get from the .NET Framework along with a few different options for control toolkits.  I tried to be fairly thorough, but know that this isnt a detailed benchmarking comparison or intense evaluation.  Its just meant to be a feature set comparison to be used when thinking about building an LOB app in WPF.  I tried to list important feature differences and notes based on my experience with the trial versions and what I found in documentation and reference materials and samples.  Ive also listed the importance of the controls based on how I think they are needed in LOB apps.  There are several toolkits available, but given I dont have unlimited time, I picked just a few.  Maybe Ill add on more later.  The toolkits I compared are: Teleriks RadControls for WPF since I had heard some good things about Telerik Infragistics NetAdvantage WPF since both I and the customer have some experience with the vendors tools WPF Toolkit on codeplex since many of my colleagues have used it Blacklight codeplex project which had WPF support for the Tile View control  (with Release 4.3 WPF is not going to be supported in favor of focusing only on SilverLight controls, so I dropped that from the comparison) Click Here to Download the WPF Control Toolkits Comparison Hopefully this helps someone out there.  Feel free to post a comment on your experiences or if you think something I listed is incorrect or missing.  Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Some Oracle VM 3 updates

  - by wcoekaer

  Today we did another patch set update for Oracle VM 3 (3.0.3-build 227). This can be downloaded from My Oracle Support as patch ID 14736185. There are quite a few updates in here and I highly recommend any Oracle VM 3 customer or user to install this update. This patch can be installed on top of Oracle VM 3.0 versions 3.0.2 and 3.0.3. The patch is cumulative for 3.0.3. So if you already installed patch update 1 (3.0.3-150) then this will just be incremental on top of that and brings you to 3.0.3-build 227. There is a readme file which contains the patchlist in the patch info. The following patches are released on ULN for Oracle VM server 3.0 : initscripts-8.45.30-2.100.18.el5.x86_64 The inittab file and the /etc/init.d scripts. kernel-ovs-2.6.32.21-45.6.x86_64 The Linux kernel kernel-ovs-firmware-2.6.32.21-45.6.x86_64 Firmware files used by the Linux kernel osc-oracle-ocfs2-0.1.0-35.el5.noarch Oracle Storage Connect ocfs2 Plugin osc-plugin-manager-1.2.8-9.el5.3.noarch Oracle Storage Connect Plugin Infrastructure osc-plugin-manager-devel-1.2.8-9.el5.3.noarch Oracle Storage Connect Plugin Development ovs-agent-3.0.3-41.6.x86_64 Agent for Oracle VM xen-4.0.0-81.el5.1.x86_64 Xen is a virtual machine monitor xen-devel-4.0.0-81.el5.1.x86_64 Development libraries for Xen tools xen-tools-4.0.0-81.el5.1.x86_64 Various tooling for the manipulation of Xen instances Errata emails will be sent in the next few days with details on the above updates. Or you will find them here. I also did an update of my Oracle VM utilities to 0.4.0. They are also available from My Oracle Support, patch ID 14736239. These utils can be unzipped and installed on the server running Oracle VM Manager. Typically in /u01/app/oracle/ovm-manager-3/ovm_utils. There is a set of man pages in /u01/app/oracle/ovm-manager-3/ovm_utils/man/man8. There now are 6 commands : ovm_vmcontrol : VM level operations ovm_servercontrol : server level operations ovm_vmdisks : virtual disk/physical location mapping for VM disks ovm_vmmessage : message passing utility between the manager and the VM tools (in the Oracle VM templates) ovm_repocontrol : repository level operations ovm_poolcontrol : pool level operations Some of the new changes : at a pool level, acknowledge events and cascade to servers and virtual machines with outstanding events at a pool level, do a rescan of the storage for fibrechannel/iscsi disks if you add new devices (it does this operation then on every running server) at a repository level, fixup a device if it had a failed create repository at a repository level, refresh the repository and this will update the free space in the UI for ocfs2 repositories at a server level, acknowledge server events and cascade to virtual machines if needed at a VM level, acknowledge VM events at a VM level, bind vcpus to cores with vcpuset/vcpuget Please see the man pages and remember that these tools are just written As Is - no SRs... (per the documentation) Hopefully they are useful.

• Installed LibreOffice 4 with ppa, how do I remove it and go back to LibreOffice 3?

  - by MMA

  EDIT This question is not at all a duplicate of How to downgrade from LibreOffice 4.0 to 3.6? The above mentioned question talks about downgrading from a specific version of LibreOffice, namely from 4.0 to 3.6. The solutions mentioned are not the ones I am looking for. They will work but I wanted a general solution without using PPA or downloading .deb files for from a higher version to a lower version. The above solutions suggest either downloading .deb files for LibreOffice 3.6 or adding repository for it. Furthermore, some of the answers put out-of-proportion~(applicable for the solution, however) stress on use of synaptic, not general command-line-solution. That made me wonder, at this very moment, if I take a fresh computer, and install Ubuntu 12.04, LibreOffice installation will work without a hitch. Then why I can not install LibreOffice in my 12.04 machine today from simple command line? This answer to my question, clarified everything. I need to use ppa-purge so that this resets all packages from a PPA to the standard versions released for my distribution. Basically it is like a way to restore my system back to the way it was before my installed packages from a PPA. This article further elaborates the idea. The above mentioned answer worked perfectly for me. Actually, this was an education for me since it taught me how do downgrade a package that was added via PPA. I had upgraded from LibreOffice 3 to LibreOffice 4 using the PPA. Now since I found that LibreOffice 4 has some issues, including handling my native language, I want to move back to LibreOffice 3. In order to accomplish this, I removed the LibreOffice config directory from my home and then purged LibreOffice from my machine. sudo apt-get purge libreoffice-* Then I removed the relevant PPA's using the sudo apt-add-repository --remove command. And then ran sudo apt-get update. Now, when I try to install LibreOffice using the command sudo apt-get install libreoffice I get an avalanche of output about unmet dependencies, something like, The following packages have unmet dependencies: libreoffice : Depends: libreoffice-core (= 1:3.5.7-0ubuntu4) but it is not going to be installed (snipped) If I dig the issue further, by using the command, sudo apt-get install libreoffice-core I get The following packages have unmet dependencies: libreoffice-core : Depends: libreoffice-common (> 1:3.5.7) but it is not going to be installed Depends: libexttextcat0 (>= 2.2-8) but it is not going to be installed Depends: ure (>= 3.5.7~) but it is not going to be installed E: Unable to correct problems, you have held broken packages. Could you please tell me how do I install LibreOffice 3 in my machine? I am using Ubuntu 12.04 LTS.

• AccelerometerInput XNA GameComponent

  - by Michael B. McLaughlin

  Bad accelerometer controls kill otherwise good games. I decided to try to do something about it. So I create an XNA GameComponent called AccelerometerInput. It’s still a beta project but you are welcome to try it, use it, modify it, etc. I’m releasing under the terms of the Microsoft Public License. Important info: First, it only supports tilt-style controls currently. I have not implemented motion-style controls yet (and make no promises as to when I might find time to do so). Second, I commented it heavily so that you can (hopefully) understand what it is doing. Please read the comments and examine the sample game for a usage overview. There are configurable parameters which I encourage you to make use of (both by modifying the default values where your testing shows it to be appropriate and also by implementing a calibration mechanism in your game that lets the user adjust those configurable values based on his or her own circumstances). Third, even with this code, accelerometer controls are still a fairly advanced topic area; you will likely find nothing but disappointment if you simply plunk this into some project without testing it on a device (or preferably on several devices). Fourth, if you do try this code and find that something doesn’t work as expected on your phone, please let me know as I want to improve it and can only do so with your help. Let me know what phone model it is, what you tried doing, what you expected, and what result you had instead. I may or may not be able to incorporate it into the code, but I can let others know at the very least so that they can make appropriate modifications to their games (I’m hopeful that all phones are reasonably similar in their workings and require, at most, a slight calibration change, but I simply don’t know). Fifth, although I’ll do my best to answer any questions you may have about it, I’m very busy with a number of things currently so it might take a little while. Please look through the code and examine the comments and sample game first before asking any questions. It’s likely that the answer is in there. If not, or if you just aren’t really sure, ask away. Sixth, there are differences between a portrait-mode game and a landscape mode game (specifically in the appropriate default tilt adjustment for toward the user/away from the user calculations). This is documented and the default is set for landscape. If you use this for a portrait game, make the appropriate change (look for the TODO: comment in AccelerometerInput.cs). Seventh, no provision whatsoever is made for disabling screen locking. It is up to you to implement that and to take appropriate measures to detect when the user has been idle for too long and timeout the game. That code is very game-specific. If you have questions about such matters, consult the relevant MSDN documentation and, if you still have questions, visit the App Hub forums and ask there. I answer questions there a lot and so I may even stumble across your question and answer it. But that’s a much better forum than the comments section here for questions of that sort so I would appreciate it if you asked idle detection-related questions there (or on some other suitable site that you may be more familiar and comfortable with). Eighth, this is an XNA GameComponent intended for XNA-based games on WP7. A sufficiently knowledgeable Silverlight developer should have no problem adapting it for use in a Silverlight game or app. I may create a Silverlight version at some point myself. Right now I do not have the time, unfortunately. Ok. Without further ado: http://www.bobtacoindustries.com/developers/utils/AccelerometerInput.zip Have a great St. Patrick’s Day!

• What does the Spring framework do? Should I use it? Why or why not?

  - by sangfroid

  So, I'm starting a brand-new project in Java, and am considering using Spring. Why am I considering Spring? Because lots of people tell me I should use Spring! Seriously, any time I've tried to get people to explain what exactly Spring is or what it does, they can never give me a straight answer. I've checked the intros on the SpringSource site, and they're either really complicated or really tutorial-focused, and none of them give me a good idea of why I should be using it, or how it will make my life easier. Sometimes people throw around the term "dependency injection", which just confuses me even more, because I think I have a different understanding of what that term means. Anyway, here's a little about my background and my app : Been developing in Java for a while, doing back-end web development. Yes, I do a ton of unit testing. To facilitate this, I typically make (at least) two versions of a method : one that uses instance variables, and one that only uses variables that are passed in to the method. The one that uses instance variables calls the other one, supplying the instance variables. When it comes time to unit test, I use Mockito to mock up the objects and then make calls to the method that doesn't use instance variables. This is what I've always understood "dependency injection" to be. My app is pretty simple, from a CS perspective. Small project, 1-2 developers to start with. Mostly CRUD-type operations with a a bunch of search thrown in. Basically a bunch of RESTful web services, plus a web front-end and then eventually some mobile clients. I'm thinking of doing the front-end in straight HTML/CSS/JS/JQuery, so no real plans to use JSP. Using Hibernate as an ORM, and Jersey to implement the webservices. I've already started coding, and am really eager to get a demo out there that I can shop around and see if anyone wants to invest. So obviously time is of the essence. I understand Spring has quite the learning curve, plus it looks like it necessitates a whole bunch of XML configuration, which I typically try to avoid like the plague. But if it can make my life easier and (especially) if make it can make development and testing faster, I'm willing to bite the bullet and learn Spring. So please. Educate me. Should I use Spring? Why or why not?

• My Automated NuGet Workflow

  - by Wes McClure

  When we develop libraries (whether internal or public), it helps to have a rapid ability to make changes and test them in a consuming application. Building Setup the library with automatic versioning and a nuspec Setup library assembly version to auto increment build and revision AssemblyInfo –> [assembly: AssemblyVersion("1.0.*")] This autoincrements build and revision based on time of build Major & Minor Major should be changed when you have breaking changes Minor should be changed once you have a solid new release During development I don’t increment these Create a nuspec, version this with the code nuspec - set version to <version>$version$</version> This uses the assembly’s version, which is auto-incrementing Make changes to code Run automated build (ruby/rake) run “rake nuget” nuget task builds nuget package and copies it to a local nuget feed I use an environment variable to point at this so I can change it on a machine level! The nuget command below assumes a nuspec is checked in called Library.nuspec next to the csproj file $projectSolution = 'src\\Library.sln' $nugetFeedPath = ENV["NuGetDevFeed"] msbuild :build => [:clean] do |msb| msb.properties :configuration => :Release msb.targets :Build msb.solution = $projectSolution end task :nuget => [:build] do sh "nuget pack src\\Library\\Library.csproj /OutputDirectory " + $nugetFeedPath end Setup the local nuget feed as a nuget package source (this is only required once per machine) Go to the consuming project Update the package Update-Package Library or Install-Package TLDR change library code run “rake nuget” run “Update-Package library” in the consuming application build/test! If you manually execute any of this process, especially copying files, you will find it a burden to develop the library and will find yourself dreading it, and even worse, making changes downstream instead of updating the shared library for everyone’s sake. Publishing Once you have a set of changes that you want to release, consider versioning and possibly increment the minor version if needed. Pick the package out of your local feed, and copy it to a public / shared feed! I have a script to do this where I can drop the package on a batch file Replace apikey with your nuget feed's apikey Take out the confirm(s) if you don't want them @ECHO off echo Upload %1? set /P anykey="Hit enter to continue " nuget push %1 apikey set /P anykey="Done " Note: helps to prune all the unnecessary versions during testing from your local feed once you are done and ready to publish TLDR consider version number run command to copy to public feed

• Booting Ubuntu on HP Pavilion g7 - 13.04 [duplicate]

  - by death2040

  This question already has an answer here: My computer boots to a black screen, what options do I have to fix it? 24 answers I have a HP Pavilion G7 with an AMD A4 processor and Radeon graphics. I want to install Ubuntu on my laptop but whenever I put the Ubuntu live CD in it and boot to it, the screen shows the Ubuntu logo and the four little dots then after about a minute or two the screen goes black. I can tell the screen is still on but it doesn't have anything on it. I'm beginning to wonder if its a driver problem but I can't really install the drivers when I cant even get Ubuntu to show anything except a loading screen. I've already tried using 12.04 and 12.10 and all the others down to Ubuntu 10. none of them worked. All the other versions don't even show the Ubuntu logo. I'd prefer to have Ubuntu 13.04 on it if its possible but I haven't had any luck finding a solution. I've also tried using WUBI installer in Windows 7 but all that did was make my computer slower for windows and it does the same with the screen when i boot it to Ubuntu. I'm trying to use Ubuntu alongside Windows 7. I cant find any solution on Google. It wont load anything and I know that there is a program called grub on Ubuntu that I used on my desktop computer when it had graphics trouble but the trouble with my desktop was minor things like the screen would flash and then show weird patterns on the screen. But I can't find anything on what to do with the HP laptop. Please help. I use this laptop a lot for games on Windows 7 and I just want to use Ubuntu for when I take my laptop to school and for school stuff. Edit: I just tried booting it in nomodeset and some other things and still didn't work. It did boot up but now when it goes to install alongside windows it crashes and says Ubuntu is forcing reboot or something like that Also, this question is different from the black screen at boot issue because when I do use nomodeset on my computer and select install Ubuntu it will go as far as the screen where you can choose to replace Windows or run alongside Windows. Then after I click continue it ejects the live CD and turns off my computer without installing anything. The error message it shows when it ejects the disk says signal 15, shutting down - modem manager [1675]: <info> Caught nm-dispatcher.action: Caught signal 15, shutting down... *Deconfiguring network interfaces... Please remove installation media and close the tray (if any) then press ENTER *Deactivating swap... *Stopping remaining crypto disks... *stopping early crypto disks... unmount: /run/lock: not mounted unmount: /run/shm: not mounted

• Unable to connect to mail server via IMAP and roundcube

  - by mrhatter

  I am having trouble getting the final parts of my mail server up and working. I followed this tutorial to get everything set up on the mail server side. I have installed roundcube for webmail and configured it but it is saying "error connecting, connection refused" when attempting to connect to it using IMAP. This is thorough the "test imap" section of its installer. Also it is giving me an error message about perissions for it's log and temp folders but that's not as important as acutally getting mail to work. I have also tried connecting to the mail server using thunderbird however it cannot establish a connection either and I know my login information is correct. I know that the databases are working correctly based on the roundcube installer telling me that they have been "successfully initialized". Here are my firewall rules -A INPUT -i lo -j ACCEPT -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 25 -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT -A INPUT -p tcp -m tcp --dport 465 -j ACCEPT -A INPUT -p tcp -m tcp --dport 487 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 993 -j ACCEPT -A INPUT -j DROP Which I set up in iptables. I have modified them from what I used in this tutorial I'm not sure what to try next. Any help would be wonderful! I am using Ubuntu 14.04 server, apache 2.4.7, roundcube 1.0.1, and the latest versions of dovecot and postfix. The email databases are contained in mysql. I am running this on a VPS server. UPDATE: I have changed from iptables to using ufw. I have run the following commands to set up a basic firewall with ufw. ufw default deny ufw allow ssh ufw allow http ufw allow https ufw allow imap ufw allow imaps ufw allow smtp I then used telnet to check all of the mail ports. But Port 993 isnt working even though ufw says both 993 and 993/tcp are open. What am I missing?

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 (thanks to Nancy, who shared this with me)  New for Smart View v11.1.2.2.103, Patch 14362638,   Microsoft Office 64-bit is now supported:  Information for 64-Bit Microsoft Office Installations: In this release, Smart View supports the 64-bit version on Microsoft Office. If you use 64-bit Office, please note the following: Oracle provides separate Smart View installation files for 64-bit and 32-bit Office systems. . smartview-x64.exe is the file for 64-bit Office installations. smartview.exe is the file for 32-bit Office installations. The 64-bit version of Smart View pertains only to the 64-bit version of Microsoft Office and not to the version of the operating system. Customers with 64-bit operating systems and the 32-bit version of Microsoft Office should install the 32-bit version of Smart View. You cannot install the 64-bit version of Smart View from EPM Workspace (13530466). Although Planning Offline is supported for 64-bit operating systems, it is not supported for 64-bit Smart View installations. If you use Planning Offline with Smart View, you must use the 32-bit version of Smart View and the 32-bit version of Microsoft Office. In 64-bit versions of Excel 2010 SP1, the presence of Smart View functions may cause Excel to terminate abruptly and may prevent Copy Data Point and Paste Data Point functions from working. This is a Microsoft issue, and a service request has been filed with Microsoft. Workaround: Until the Microsoft fix, use the 32-bit version of Smart View. (13606492) The Smart View function migration utility is not supported on 64-bit Office.

• Emaroo 1.4.0 Released

  - by WeigeltRo

  Emaroo is a free utility for browsing most recently used (MRU) lists of various applications. Quickly open files, jump to their folder in Windows Explorer, copy their path - all with just a few keystrokes or mouse clicks. tl;dr: Emaroo 1.4.0 is out, go download it on www.roland-weigelt.de/emaroo   Why Emaroo? Let me give you a few examples. Let’s assume you have pinned Emaroo to the first spot on the task bar so you can start it by hitting Win+1. To start one of the most recently used Visual Studio solutions you type Win+1, [maybe arrow key down a few times], Enter This means that you can start the most recent solution simply by Win+1, Enter What else? If you want to open an Explorer window at the file location of the solution, you type Ctrl+E instead of Enter.   If you know that the solution contains “foo” in its name, you can type “foo” to filter the list. Because this is not a general purpose search like e.g. the Search charm, but instead operates only on the MRU list of a single application, you usually have to type only a few characters until you can press Enter or Ctrl+E.   Ctrl+C copies the file path of the selected MRU item, Ctrl+Shift+C copies the directory If you have several versions of Visual Studio installed, the context menu lets you open a solution in a higher version.   Using the context menu, you can open a Visual Studio solution in Blend. So far I have only mentioned Visual Studio, but Emaroo knows about other applications, too. It remembers the last application you used, you can change between applications with the left/right arrow or accelerator keys. Press F1 or click the Emaroo icon (the tab to the right) for a quick reference. Which applications does Emaroo know about? Emaroo knows the MRU lists of Visual Studio 2008/2010/2012/2013 Expression Blend 4, Blend for Visual Studio 2012, Blend for Visual Studio 2013 Microsoft Word 2007/2010/2013 Microsoft Excel 2007/2010/2013 Microsoft PowerPoint 2007/2010/2013 Photoshop CS6 IrfanView (most recently used directories) Windows Explorer (directories most recently typed into the address bar) Applications that are not installed aren’t shown, of course. Where can I download it? On the Emaroo website: www.roland-weigelt.de/emaroo Have fun!

• Legality of similar games

  - by Jamie Taylor

  This is my first question on GD.SE, and I hope it's in the right place. A little background: I'm an amateur (read: not explicitly employed to develop games, but am employed as a software developer) game developer and took a ComSci with Games Development degree. My Question: What is the legal situation/standpoint of creating a copycat title? I know that there are only N number of ways of solving a problem, and N number of ways to design a piece of software. Say that an independent developer designed a copycat game (a Tetris clone in this example) for instance, and decided to use that game to generate income for themselves as well as interest for their other products. Say the developer adds a disclaimer into the software along the lines of "based on , originally released c. by ." Are there any legal problems/grey areas with the developer in this example releasing this game, commercially? Would they run into legal problems? Should the developer in this example expect cease and desist orders or law suit claims from original publishers? Have original publishers been known to, effectively, kill independent projects because they are a little too close to older titles? I know that there was, at least, one attempt by a group of independent developers to remake Sonic the Hedgehog 2 and Sega shut them down. I also know of Sega shutting down development of the independent Streets of Rage Remake. I know that "but it's an old game, your honour," isn't a great legal standpoint when it comes to defending yourself. But, could an independent developer have a law suit filed against them for re-implementing an older title in a new way? I know that there are a lot of copycat versions of the older titles like Tetris available on app stores (and similar services), and that it would be very difficult for a major publisher to shut them all down. Regardless of this, is making a Tetris (or other game) copycat/clone illegal? We were taught lots of different things at University, but we never covered copyright law. I'm presuming that their thought behind it was "IF these students get jobs in games development, they wont need to know anything about the legal side of it, because their employers will have legal departments... presumably" tl;dr Is it illegal to create a clone or copycat of an old title, and make money from it?
