  • When should one use the following: Amazon EC2, Google App Engine, Microsoft Azure and Salesforce.com

    - by vicky21
    I am asking this in very general sense. Both from cloud provider and cloud consumer's perspective. Also the question is not for any specific kind of application (in fact the intention is to know which type of applications/domains can fit into which of the cloud slab -SaaS PaaS IaaS). My understanding so far is: IaaS: Raw Hardware (Processors, Networks, Storage). PaaS: OS, System Softwares, Development Framework, Virtual Machines. SaaS: Software Applications. It would be great if Stackoverflower's can share their understanding and experiences of cloud computing concept. EDIT: Ok, I will put it in more specific way - Amazon EC2: You don't have control over hardware layer. But you can take your choice of OS image, Dev Framework (.NET, J2EE, LAMP) and Application and put it on EC2 hardware. Can you deploy an applications built with Google App Engine or Azure on EC2? Google App Engine: You don't have control over hardware and OS and you get a specific Dev Framework to build your application. Can you take any existing Java or Python application and port it to GAE? Or vice versa, can applications that were built on GAE be taken out of GAE and ported to any Application Server like Websphere or Weblogic? Azure: You don't have control over hardware and OS and you get a specific Dev Framework to build your application. Can you take any existing .NET application and port it to Azure? Or vice versa, can applications that were built on Azure be taken out of Azure and ported to any Application Server like Biztalk?

  • Linking errors when building against Boost Unit Test Framework

    - by Rafid
    I am trying to use Boost Unit Test Framework by building a stand alone library as detailed here: http://www.boost.org/doc/libs/1_35_0/libs/test/doc/components/utf/compilation.html So I created a VC library project containing the mentioned files and build it and it was successful. Then I created a test project and referenced the library project I just created, but when I tried to build it, I got the following linking errors: 1>Type.obj : error LNK2019: unresolved external symbol "bool __cdecl boost::test_tools::tt_detail::check_impl(class boost::test_tools::predicate_result const &,class boost::unit_test::lazy_ostream const &,class boost::unit_test::basic_cstring<char const >,unsigned __int64,enum boost::test_tools::tt_detail::tool_level,enum boost::test_tools::tt_detail::check_type,unsigned __int64,...)"

Any ideas?!

  • Control third check box based on the state of the first two using jquery

    - by Moj
    I have three check boxes and need to disable the third if either and/or of the other two are checked. I'm sure there's a easier way than what I have currently. It's turning into what I believe is a mess and I'm hoping that someone with more jquery knowledge can shine the light here. Here's my simple html form: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script src="custom.js" type="text/javascript"></script> </head> <body> <input type="checkbox" class="class" id="1">First <input type="checkbox" class="class" id="2">Second <input type="checkbox" class="class" id="3">Third </body> </html> Here's the javascript I'm using with jquery v1.4.2 jQuery(document).ready(function() { // watches the events of all checkboxes $(":checkbox").click(function(){ if( // if both 1 and 2 are checked we don't want to enable Third until both are unchecked. (($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))|| ((($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled')))|| ((($('#1:checkbox').attr('checked'))||($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled'))) ){ // we don't want to do anything in the above events } else if( // handles the First check box (($('#1:checkbox').attr('checked'))||(!$('#1:checkbox').attr('checked')))|| // handles the Second check box (($('#2:checkbox').attr('checked'))||(!$('#2:checkbox').attr('checked'))) ){ // call the disableThird function disableThird(); } }); // handles enabling and disabling the Third checkbox function disableThird(){ var $checkbox = $('#3:checkbox'); $checkbox.attr('disabled', !$checkbox.attr('disabled')); }; }); For some reason checking #3 will disable it's self. I don't understand why. This works, but one of the requirements is that a non programmer should be able to edit and maintain this. Ideally it'd be great if he could just add new check boxes to the html and it would work. The class for these are define and as far as I know can't be changed. The last check box in the list of check boxes will disable if any of the ones above are selected. Like wise if the last check box is selected, it will disable all the ones above it. I haven't even begun writing and testing that portion as this is quickly becoming too complicated for a non programmer to handle. I myself am more of a PHP coder than a js, let alone jquery, coder. Any help would be greatly appreciated.

  • TPL v/s Reactive Framework

    - by Abhijeet Patel
    When would one choose to use Rx over TPL or are the 2 frameworks orthogonal? From what I understand Rx is primarily intended to provide an abstraction over events and allow composition but it also allows for providing an abstraction over async operations. using the Createxx overloads and the Fromxxx overloads and cancellation via disposing the IDisposable returned. TPL also provides an abstraction for operations via Task and cancellation abilities. My dilemma is when to use which and for what scenarios?

  • Silverlight RichTextBox Disable Mouse Selection

    - by Fastidious
    I am writing a custom control based on RichTextBox that needs the ability to process MouseLeftButtonDown events but must not allow user-initiated selection (I'm doing everything programmatically). I tried setting a flag in MouseLeftButtonDown to track dragging and then continuously setting the RichTextBox.Selection to nothing in the MouseMove event but the move event isn't fired until after I release the mouse button. Any ideas on how to solve this? Thanks.

  • ListView Long Click Animation

    - by spaceboy2000
    I would like to capture long click events in a ListView, which was easily done using a OnItemLongClickListener. However, that lacks the fading animation of the selector transitioning to a long press that is seen when the long click is handled by onCreateContextMenu. How can I get that animation using OnItemLongClickListener?

  • How do I debug a crash when I run my garbage-collected app in Rosetta?

    - by Rob Keniger
    I have a Universal app which is targeting 10.5 and which uses garbage collection. I am building for ppc, i386 and x86_64. I don't have access to a physical PowerPC machine so I am trying to use Rosetta to confirm that the PowerPC portion of the app works correctly. However, as soon as the app is launched in Rosetta it immediately crashes with the following crash log: Process: FooApp [91567] Path: /Users/rob/Development/src/FooApp/build/Release 64-bit/FooApp.app/Contents/MacOS/FooApp Identifier: com.companyX.FooApp Version: 0.9 (build d540e05) (2) Code Type: PPC (Translated) Parent Process: launchd [708] Date/Time: 2010-04-09 18:32:23.962 +1000 OS Version: Mac OS X 10.6.3 (10D573) Report Version: 6 Exception Type: EXC_CRASH (SIGTRAP) Exception Codes: 0x0000000000000000, 0x0000000000000000 Crashed Thread: 5 ...snip non-relevant threads...

It looks like the Garbage Collector is failing very badly. Are garbage-collected PowerPC apps not supported in Rosetta? I can't see any mention of this limitation in the docs if so. Does anyone have any ideas?

  • Izpack: Creating custom panels

    - by bguiz
    Hi, I am trying to create a custom panel for an IzPack installer. This means that I have to extend IzPanel. However, it appears that if I do this, the extended panel needs to be in the com.izforge.izpack.panels package. Then I found this post, which stipulates that: As such, you must include installer.jar from the lib folder of IzPack in the build path of your custom panel project. Your custom panel /must/ extend com.izforge.izpack.installer.IzPanel. Furthermore, it /must/ reside in the com.izforge.izpack.panels package. On top of it all, your build jar's name /must/ be the same as the unqualified name of your custom panel class. I take issue with the 1st and 4th points. They imply that I have to create an additional JAR file for each custom IzPanel that I create. Also, I would have to modify the IzPack installation by adding these JARs to one of its subdirectories. Is this article outdated (2008) and can it be safely ignored, or is this still true? If not how can I avoid this and simply have the extended IzPanel on the classpath instead? Thank you!

  • Can YAML have inheritance?

    - by Jason
    This question involves a lot of symfony but it should be easy enough for someone to follow who only knows YAML and not symfony. My symfony models come from a three-step process: First, I create the tables in MySQL. Second, I run a symfony command (symfony doctrine:build-schema) to convert my table structure into a YAML file. Third, I run another symfony command (symfony doctrine:build-model) to convert the YAML file into PHP code. Here's the problem: there are some tables in the database that I don't want to end up in my symfony code. For example, let's say I have two tables: one called my_table and another called wordpress. The YAML file I end up with might look like this: MyTable: connection: doctrine tableName: my_table Wordpress: connection: doctrine tableName: wordpress That's great except the wordpress table has nothing to do with my symfony models. The result is that every single time I make a change to my database and generate this YAML file, I have to manually remove wordpress. It's annoying! I'd like to be able to create a file called baseConfig.php or something that looks like this: $config = array( 'MyTable' => array( 'connection' => 'doctrine', 'tableName' => 'my_table', ), 'Wordpress' => array( 'connection' => 'doctrine', 'tableName' => 'wordpress', ), ); And then I could have a separate file called config.php or something where I could make modifications to the base config: unset($config['Wordpress']); So my question is: is there any way to convert YAML into executable PHP code (as opposed to load YAML INTO PHP code like what sfYaml::load() does) to achieve this sort of thing? Or is there maybe some other way to achieve YAML inheritance? Thanks, Jason

  • Blackberry Development, adding dynamic number of buttons and setting Fieldchangelistener() for them

    - by Nikesh Yadav
    Hi, I am adding dynamic number of buttons in a Blackberry application and trying to get different events on each button click. I am not able to apply the setchangelistener() for these array of buttons as once the loop finishes after adding all the buttons, the events gets generated only for the last indexed button. If I make us of getIndex(), it runs fine only if I am not adding any other fields on my screen, but if I add other fields along with these array of buttons, the getIndex() function count them in the indexing as well. Can anyone please help me out in setting FieldChangeListener to array of ButtonField? Here is a sample code of the way I am using the array of ButtonField. I the code I have added two test LabelField at the top of the screen, if I remove them the code will run fine and I will get different result for each button click, but if I keep them active, the indexing gets effected and the Button wont work. package buttonclickloop; import net.rim.device.api.ui.DrawStyle; import net.rim.device.api.ui.Field; import net.rim.device.api.ui.FieldChangeListener; import net.rim.device.api.ui.component.ButtonField; import net.rim.device.api.ui.component.LabelField; import net.rim.device.api.ui.container.HorizontalFieldManager; import net.rim.device.api.ui.container.MainScreen; public class ButtoncClickLoop extends MainScreen { int i = 0; private ButtonField[] btn = new ButtonField[50]; public ButtoncClickLoop() { // TODO Auto-generated constructor stub LabelField Field1 = new LabelField("Field1"); LabelField Field2 = new LabelField("Field2",DrawStyle.RIGHT | ButtonField.USE_ALL_WIDTH); HorizontalFieldManager FieldHmgr = new HorizontalFieldManager(); FieldHmgr.add(Field1); FieldHmgr.add(Field2); FieldHmgr.setMargin(0,0,10,5); add(FieldHmgr); while (i < 3){ FieldChangeListener listener = new FieldChangeListener() { public void fieldChanged(Field field, int context) { context = field.getIndex(); if (field == btn[context]){ add(new LabelField("Label" + context + "")); } } }; btn[i] = new ButtonField("Button" + i + ""); btn[i].setChangeListener(listener); add(btn[i]); i = i + 1; } } } Thanks, Nikesh

  • Public key of Android project and keystore created in Eclipse?

    - by user578056
    I created an Android project using Eclipse (under Windows FWIW) and let Eclipse create the keypair during the Export Android Application process. I successfully used Eclipse to make a signed release build that is now on the Market. Now I want to now use ProGuard, which I believe means using Ant instead of Eclipse to build. It was a pain, but Ant building works in both debug and release, until it tries to sign the APK. I get: [signjar] jarsigner: Certificate chain not found for: redacted. redacted must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain. keytool -list -keystore redacted gives me: Keystore type: JKS Keystore provider: SUN Your keystore contains 1 entry redacted, Jan 16, 2011, PrivateKeyEntry, Certificate fingerprint (MD5): BD:0F:70:C1:39:F5:FE:5B:BC:CD:89:0B:C8:66:95:E0 Which brings me to the actual question: where is my public key? I have some sort of public key on my Android Market profile, but is that the pair for my private key? If so, how do I store that in the keystore so that jarsigner will work?

  • Visual studio 2010 setup project problem.

    - by Guru
    Hi there, I've made an application that uses .NET framework 3.5 SP1 and SQL Server 2008 Express. Application is fine and now i'm going to to make a setup project for this. When I first build my setup it was fine as all the prerequisites were not included in setup. But I want my setup to install .NET 3.5 SP1 and SQL SERVER 2008 Express also. So for this I've changed the options in setup project's properties from "Download prerequisites from following location" to "Download prerequisites from the same location as my application". In addition to that I've also checked the options above like .NET 3.5 SP1 and SQL Server 2008 Express etc. After doing all this I build my project again. This time I'm Getting 57 Errors. Error 1 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'DotNetFX35SP1\dotNetFX20\aspnet.msp' in item '.NET Framework 3.5 SP1' can not be located on disk.

  • Dealing with asynchronous control structures (Fluent Interface?)

    - by Christophe Herreman
    The initialization code of our Flex application is doing a series of asynchronous calls to check user credentials, load external data, connecting to a JMS topic, etc. Depending on the context the application runs in, some of these calls are not executed or executed with different parameters. Since all of these calls happen asynchronously, the code controlling them is hard to read, understand, maintain and test. For each call, we need to have some callback mechanism in which we decide what call to execute next. I was wondering if anyone had experimented with wrapping these calls in executable units and having a Fluent Interface (FI) that would connect and control them. From the top of my head, the code might look something like: var asyncChain:AsyncChain = execute(LoadSystemSettings) .execute(LoadAppContext) .if(IsAutologin) .execute(AutoLogin) .else() .execute(ShowLoginScreen) .etc; asyncChain.execute(); The AsyncChain would be an execution tree, build with the FI (and we could of course also build one without a FI). This might be an interesting idea for environments that run in a single threaded model like the Flash Player, Silverlight, JavaFX?, ... Before I dive into the code to try things out, I was hoping to get some feedback.

  • C++ resize a docked Qt QDockWidget programmatically?

    - by Zac
    I've just started working on a new C++/Qt project. It's going to be an MDI-based IDE with docked widgets for things like the file tree, object browser, compiler output, etc. One thing is bugging me so far though: I can't figure out how to programmatically make a QDockWidget smaller. For example, this snippet creates my bottom dock window, "Build Information": m_compilerOutput = new QTextEdit; m_compilerOutput->setReadOnly(true); dock = new QDockWidget(tr("Build Information"), this); dock->setWidget(m_compilerOutput); addDockWidget(Qt::BottomDockWidgetArea, dock); When launched, my program looks like this: http://yfrog.com/6ldreamidep (bear in mind the early stage of development) However, I want it to appear like this: http://yfrog.com/20dreamide2p I can't seem to get this to happen. The Qt Reference on QDockWidget says this: Custom size hints, minimum and maximum sizes and size policies should be implemented in the child widget. QDockWidget will respect them, adjusting its own constraints to include the frame and title. Size constraints should not be set on the QDockWidget itself, because they change depending on whether it is docked Now, this suggests that one method of going about doing this would be to sub-class QTextEdit and override the sizeHint() method. However, I would prefer not to do this just for that purpose, nor have I tried it to find that to be a working solution. I have tried calling dock-resize(m_compilerOutput-width(), m_compilerOutput-minimumHeight()), calling m_compilerOutput-setSizePolicy() with each of its options...nothing so far has affected the size. Like I said, I would prefer a simple solution in a few lines of code to having to create a sub-class just to change sizeHint(). All suggestions are appreciated.

  • Resolving MSBuild 4.0 warnings

    I've upgraded a solution to use MSBuild 4.0. It compiles but I get lots of warnings, for example: "T:\projects\Castle.Core\buildscripts\Build.proj" (Package target) (1) - "T:\projects\Castle.Core\Castle.Core-vs2008.sln" (Build target) (2:2) - "T:\projects\Castle.Core\src\Castle.DynamicProxy.Tests\Castle.DynamicProxy.Tests-vs2008.csproj" (default target) (3:2) - D:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(847,9): warning MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.0.30319" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend. [T:\projects\Castle.Core\src\Castle.DynamicProxy.Tests\Castle.DynamicProxy.Tests-vs2008.csproj] How can I fix these warnings? It is related to .NET 4.0 Multitargeting pack or SDK, but there's no SDK for .NET 4.0 AFAIK and Multi-Target pack can not be installed separatly. Any ideas would be appreciated.

  • Binding the textDidChange event on a NSTextField to a MacRuby delegate

    - by kolrie
    I have a NSTextField within a Window and I created a very simple MacRuby delegate: class ServerInputDelegate attr_accessor :parent def textDidChange(notification) NSLog notification.inspect parent.filter end end And I have tried setting the control's delegate: I have tried setting the Window and every other object I could think of to this delegate. I have also tried setting it to other delegates (application for instance) and events like applicationDidFinishLaunching are being properly triggered. Is there any trick I am missing in order for this event to be triggered every time the contents of this NSTextField changes?

  • GH-Unit for unit testing Objective-C code, why am I getting linking errors?

    - by djhworld
    Hi there, I'm trying to dive into the quite frankly terrible world of unit testing using Xcode (such a convoluted process it seems.) Basically I have this test class, attempting to test my Show.h class #import <GHUnit/GHUnit.h> #import "Show.h" @interface ShowTest : GHTestCase { } @end @implementation ShowTest - (void)testShowCreate { Show *s = [[Show alloc] init]; GHAssertNotNil(s,@"Was nil."); } @end However when I try to build and run my tests it moans with this error: - Undefined symbols: "_OBJC_CLASS_$_Show", referenced from: __objc_classrefs__DATA@0 in ShowTest.o ld: symbol(s) not found collect2: ld returned 1 exit status Now I'm presuming this is a linking error. I tried following every step in the instructions located here: - http://github.com/gabriel/gh-unit/blob/master/README.md And step 2 of these instructions confused me: - In the Target 'Tests' Info window, General tab: Add a linked library, under Mac OS X 10.5 SDK section, select GHUnit.framework Add a linked library, select your project. Add a direct dependency, and select your project. (This will cause your application or framework to build before the test target.) How am I supposed to add my project to the linked library list when all it accepts it .dylib, .framework and .o files. I'm confused! Thanks for any help that is received.

  • Creating a dynamic linq query

    - by Bas
    I have the following query: from p in dataContext.Repository<IPerson>() join spp1 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp1.PersonId join s1 in dataContext.Repository<ISports>() on spp1.SportsId equals s1.Id join spp2 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp2.PersonId join s2 in dataContext.Repository<ISports>() on spp2.SportsId equals s2.Id where s1.Name == "Soccer" && s2.Name == "Tennis" select new { p.Id }; It selects all the person who play Soccer and Tennis. On runtime the user can select other tags to add to the query, for instance: "Hockey". now my question is, how could I dynamically add "Hockey" to the query? If "Hockey" is added to the query, it would look like this: from p in dataContext.Repository<IPerson>() join spp1 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp1.PersonId join s1 in dataContext.Repository<ISports>() on spp1.SportsId equals s1.Id join spp2 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp2.PersonId join s2 in dataContext.Repository<ISports>() on spp2.SportsId equals s2.Id join spp3 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp3.PersonId join s3 in dataContext.Repository<ISports>() on spp3.SportsId equals s3.Id where s1.Name == "Soccer" && s2.Name == "Tennis" && s3.Name == "Hockey" select new { p.Id }; It would be preferable if the query is build up dynamically like: private void queryTagBuilder(List<string> tags) { IDataContext dataContext = new LinqToSqlContext(new L2S.DataContext()); foreach(string tag in tags) { //Build the query? } } Anyone has an idea on how to set this up correctly? Thanks in advance!

  • Deploy multiple instances of an EAR (representing versions) to Glassfish

    - by Thorbjørn Ravn Andersen
    I basically want to be able to deploy multiple versions of the same EAR file to the same server (Glassfish instance?) , and have a unique path to each version separating them. From my reading on this it appears that multiple EARs deploy to the root of the web server namespace so that they can coexist if they do not have colliding context-root's of WAR's. In my case I'd rather have that instead of everything going under "/", I'd like to be able to brand a given EAR-file build to ALWAYS deploy under a given path like "/foo-20100319" or "/foo-CUSTOMER-20010101". This can easily be done with a single WAR file just by renaming it. I do not need or want them to disturb each other. It is my understanding that this remapping is outside the scope of the application.xml file, so I found that http://docs.sun.com/app/docs/doc/820-7693/beayr?a=view says that I can specify web-uri and context-root, but I am not certain that what I wish to do, can be specified with these in Glassfish. How should I approach this? I have full control over the build process. (I have found http://stackoverflow.com/questions/877390/deploying-multiple-java-web-apps-to-glassfish-in-one-go but I am not certain how to apply this to what I need).
