  • volatile vs. mutable in C++

    - by skydoor
    Hi I have a question about the difference between volatile and mutable. I noticed that both of the two means that it could be changed. What else? Are they the same thing? What's the difference? Where are they applicable? Why the two ideas are proposed? How to use them in different way? Thanks a lot.

  • Processing incoming emails on Heroku

    - by Jerry Cheung
    For my side project kwiqi, I use ActionMailer's 'receive' method to process incoming email messages for tracking my expenses. Heroku doesn't have a local mail server running that same code will not work. One solution I've thought of is to periodically hit a controller action that will pull messages from Gmail. Are there other solutions that are reasonable? Is anyone processing incoming emails in Heroku?

  • Sales by Category in Magento?

    - by Tegan Snyder
    We have a category called "Clearance" on our Magento website. Ideally it would be nice to be able to get a report of all orders sold in that category. Is there anyway I can join the orders collection with the products collection and filter by category id? Here is a similar thread: http://www.magentocommerce.com/boards/viewthread/44296/ Any ideas, or am I crazy? It doesn't need to be pretty.

  • What is the purpose of the CreateSilverlight.js?

    - by mattruma
    I am trying to get out of browser support working for my Silverlight application and keep bumping into examples that reference CreateSilverlight.js. Looks like it has a variety of options to configure the the Silverlight experience for the end user. Is this a Microsoft javascript file for Silverlight? If so, where would I find it? I would have expected it to have already been added to my Silverlight project. Any help would be appreciated!

  • Using a visual tool to view changes on git repository

    - by Phuong Nguy?n
    I'm coming to an existing project in which people used git to track everything from scratch. I want to have a tool to view the differences between several commits. gitk does a good job, but talking about human readability, it's does not facilitate me much. Is there a better solution? I'm looking for a set of tools that allow me to easily compare branches (some how like winmerge - Display two version in parallel and highlight the changes), and running on Mac.

  • Replicating multicolumn lists from the Django admin CSS

    - by mfalcon
    Hi, I'm developing a Django project and I've to show a multicolumn list for the different objects of a table. I like the design of the django-admin for showing list-objects so I looked at the code to see how it works. As I am a CSS begginer the code seemed a bit difficult and extensive to comprehend. Is there a simplier way to make what I want or actually the CSS code of the django-admin is the path to follow?

  • VerifyError When Running jUnit Test on Android 1.6

    - by DKnowles
    Here's what I'm trying to run on Android 1.6: package com.healthlogger.test; public class AllTests extends TestSuite { public static Test suite() { return new TestSuiteBuilder(AllTests.class).includeAllPackagesUnderHere().build(); } } and: package com.healthlogger.test; public class RecordTest extends AndroidTestCase { /** * Ensures that the constructor will not take a null data tag. */ @Test(expected=AssertionFailedError.class) public void testNullDataTagInConstructor() { Record r = new Record(null, Calendar.getInstance(), "Data"); fail("Failed to catch null data tag."); } } The main project is HealthLogger. These are run from a separate test project (HealthLoggerTest). HealthLogger and jUnit4 are in HealthLoggerTest's build path. jUnit4 is also in HealthLogger's build path. The class "Record" is located in com.healthlogger. Commenting out the "@Test..." and "Record r..." lines allows this test to run. When they are uncommented, I get a VerifyError exception. I am severely blocked by this; why is it happening? EDIT: some info from logcat after the crash: E/AndroidRuntime( 3723): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 3723): java.lang.VerifyError: com.healthlogger.test.RecordTest E/AndroidRuntime( 3723): at java.lang.Class.getDeclaredConstructors(Native Method) E/AndroidRuntime( 3723): at java.lang.Class.getConstructors(Class.java:507) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.hasValidConstructor(TestGrouping.java:226) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.apply(TestGrouping.java:215) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.apply(TestGrouping.java:211) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.select(TestGrouping.java:170) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.selectTestClasses(TestGrouping.java:160) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.testCaseClassesInPackage(TestGrouping.java:154) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.addPackagesRecursive(TestGrouping.java:115) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestSuiteBuilder.includePackages(TestSuiteBuilder.java:103) E/AndroidRuntime( 3723): at android.test.InstrumentationTestRunner.onCreate(InstrumentationTestRunner.java:321) E/AndroidRuntime( 3723): at android.app.ActivityThread.handleBindApplication(ActivityThread.java:3848) E/AndroidRuntime( 3723): at android.app.ActivityThread.access$2800(ActivityThread.java:116) E/AndroidRuntime( 3723): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1831) E/AndroidRuntime( 3723): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 3723): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 3723): at android.app.ActivityThread.main(ActivityThread.java:4203) E/AndroidRuntime( 3723): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 3723): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 3723): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) E/AndroidRuntime( 3723): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) E/AndroidRuntime( 3723): at dalvik.system.NativeStart.main(Native Method)

  • Why does "request.getUserPrincipal().getName()" sometimes return a blank string?

    - by Marcus
    Has somebody an idea, why the getName method of the requests getUserPrincipal Method sometimes provides an empty String? Most of the time it returns the correct user name but not every time. This behaviour does occur randonmly. I can start the application, run the command and it works. The next time I start the application and run the command (exactly the same way as before!) it does not work... Any ideas?

  • Error with varchar(max) column when using net.sourceforge.jtds.jdbc.Driver

    - by Rihan Meij
    Hi I have a MS SQL database running (MS SQL 2005) and am connecting to it via the net.sourceforge.jtds.jdbc.Driver. The query works fine for all the columns except one that is a varchar(max). Any ideas how to get around this issues? I am using the jdbc driver to run a data index into a SOLR implementation. (I do not control the database, so the first prize solution would be where I can tweak the SQL command to get the desired results) Thanks
