Meaning of vtkMRMLNode::ModifiedSinceRead

From Julien - May 16, 2012:
What is the exact meaning of vtkMRMLNode::ModifiedSinceRead ?
From what I understand, it is a flag set to true if the "data" (e.g. vtkImageData, vtkPolyData) associated to the node has been modified since it has been set and observed.
Currently, this information is only used by the Save Data dialog to know if the "data" needs to be saved or not. In the future, I believe it should be used by the SceneView node to know when saving "data".
If my understanding is correct, then I don't understand your fix. Can you please comment ?
Also, wouldn't it make sense that ModifiedSinceRead becomes a vtkMRMLStorableNode property instead of a vtkMRMLNode property? 

Linux dashboard issues

Hi Folks, 

I tried few things and I failed to prevent the crash :( 
Looking at the note of issue 2075 [1] will provide you with the details of what I tried. 

We could probably envision updating to Ubuntu 10.04 LTS. Especially considering Ubuntu 8.04 LTS desktop ended "its life" in May 2011. See roadmap [2]

If packages created on Ubuntu 10.04 doesn't work, it also probably mean we will have to setup Virtual machine for OpenSuse / fedora / centOs. (This is something to keep in mind .. it doesn't mean we will implement it right away)

Let me know what you think.

Thanks
Jc
