• Defining relationship in value objects using Hibernate

  - by kate

  Hi, We have three tables .We need to get data from these tables based upon particular conditions. Like if TableA.columv=TableB.columc=tableC.column then get data.

• Standard library function in R for finding the mode?

  - by Nick

  In statistical language R, mean() and median() are standard functions which do what you'd expect. mode() tells you the internal storage mode of the R object, not the value that occurs the most in its argument. But surely there is a standard library function that implements mode for a vector (or list).

• Microsoft Surface: "Read" the tag value of an IdentityTag

  - by sofri

  Hi, is it possible to read the value of an IdentityTag if you place it on the TagVisualizer, without having initalized it before? I would like to use the tags for registering a new object on the Surface but having all the "free" IdentityTags in a Collection for initalizing them all... There must be a better way to do in I think. But the TagVisualizer doesn't seem to do anything when you put a tag on it that it doesn't know.

  - by dontWatchMyProfile

  Does that mean that if I delete an managed object which has references (relationship) to some others, the relationships are removed to those others? Example: objectA references objectB and objectC. objectA gets deleted, it's relationship to objectB and objectC is set to the Nullify rule. What happens in detail?

• Question regarding the method local innerclasses accesing the local variables of the method

  - by flash

  Hi I was going through the SCJP book about the innerclasses, and found this statement, it goes something like this. "A method local class can only refer to the local variables which are marked final" and in the explanation the reason specified is about the scope and lifetime of the local class object and the local variables on the heap, But I am unable to understand that.am I missing anything here about 'final'??

• Higher level database layer for Android?

  - by sweetiecakes

  Are there any good database abstraction layers/object relational mappers/ActiveRecord implementations/whatever they are called for Android? I'm aware that db4o is officially supported, but it has quite a large footprint and I'd rather use a more conventional database (SQLite).

• Any samples of MVC2 + Silverlight 4? Visual Studio 2010 does not organize the files correctly.

  - by punkouter

  I create a SL4 Application and then I say I want to create a MVC site in addition.

Does anyone know any small sample code anywhere that shows how to set up various .xap files within a MVC app. It should be simple. (I want to put the MVC2 app into Azure once I get this working)

• Plotting and Animating 2D points with 'headings'

  - by mellort

  I will have a set of data (x, y, heading), and I need to animate it in real-time. I am currently using matplotlib to animate (x, y) and it works fine, but I would really like to have some way to indicate heading, ie what direction the object is facing. What would be the best library for this? It seems like PyGame might be able to help me out, but would I have to roll out my own graphing library for it? Thanks

• SharePoint 2007 lists webservice - identify revision of list item

  - by Robert MacLean

  Using the lists webservice I retrieve the items from a list. In the XML returned I can see the attribute ows__IsCurrentVersion="1" which I assume is the same as the file object model (i.e. a boolean to say if it is current or not). However I do not see a way to identify what revision it is? What should that attribute be?

• Django ModelAdmin.save_model() -vs- ModelAdmin.save_formset()

  - by anonymous coward

  I want to ensure that a user editing a particular model is saved in that models updated_by (FK User) field. I'm using mostly ModelForms (not necessarily the built in Admin), and wondering: In what cases would I need to override ModelAdmin.save_model() or ModelAdmin.save_formset()? Or, is that doing it wrong? If it's just the models' save() method that needs to be overridden, is there a proper way to access the request object there?
