When i run gnome-terminal with the -e to execute a command the PATH used to find the command is not the PATH used in the terminal initiating the command
For example:
I open an terminal and set the PATH to be "./:$PATH
type in gnome-terminal -e cluster_node
It can't find the cluster node.
if I type gnome-terminal -e ./cluster_node it works
If I add in the /etc/environemtn the PATH ./ then it works always/
I think it doesn't use theterminal environment PATH from which it was launched.

Getting Value from Big Data Variety
Richard Tomlinson, Director, Product Management, Oracle
Big data variety implies big data complexity. Performing analytics on diverse data typically involves mashing up structured, semi-structured and unstructured content. So how can we do this effectively to get real value? How do we relate diverse content so we can start to analyze it? This session looks at how we approach this tricky problem using Endeca Information Discovery. [30 mins]
How To Leverage Your Investment In Oracle Business Intelligence Enterprise Edition Within a Big Data Architecture
Oracle ACE Director Kevin McGinley

New event from Microsoft about new techonologies which are going to be released during the current year. What can we say about these new technologies? Many advertising without exceptional ideas. Unfortunately it is true for the whole industry - the only idea from the far future is clouding computing which is not relevant to the really new approach in development. I understand that we can provide facilitation to the development community as well as new UI features for the end-users but in fact the...(read more)
In Part 1: The Challenge, published this time last week, I introduced a "brain teaser". The brain teaser asks you to figure out how to allow images and other files to be meaningfully dropped onto a NetBeans Platform application, i.e., on the drop something useful should happen with the dropped file: if the file is an image, the image should open in the IDE; if the file is a PDF document, the PDF viewer should open externally; if the file is a text file, it should open as a text in the IDE, etc.
Solution. And here is the solution:
http://bits.netbeans.org/dev/javadoc/org-openide-windows/org/openide/windows/ExternalDropHandler.html
When an implementation of the "ExternalDropHandler" class is available in the global Lookup, and
an object is being dragged over some part of the main window, the window system may call the methods of this class to decide whether it can
accept or reject the drag operation. And when the object is actually dropped, this class will be asked to handle the drop.
OK, so go ahead and implement the above class and put it into the Lookup.
Or... guess what? The NetBeans Platform has a default implementation of the above class, appropriately named "DefaultExternalDropHandler". Not only is this useful to learn about how to implement the ExternalDropHandler class (i.e., by reading the source here): you can simply include the module that contains this class in your own NetBeans Platform application and then your application will be able to receive external drag/drop events and do something meaningful with them thanks to the DefaultExternalDropHandler.
Do this:
Open your NetBeans Platform application in NetBeans IDE. Right-click the application in the Projects window and choose Properties.
In the Libraries tab, expand the "ide" cluster, and select "User Utilities". (That's where "DefaultExternalDropHandler.java" is found and registered in the Lookup.) Now click the "Resolve" button, if it appears, because some additional related modules need to now be included, if they haven't been included yet.
Again in the "ide" cluster in the Libraries tab, select "Image". That's the Image Editor. Click OK.
Run the application. Drag an image or some other type of file into your application, from outside the application, and you'll see the application tries to handle the drop. If the file being dragged is an image, it will open in the Image Editor, which you included in the previous step of these instructions.
Hurray, you're done. Without any programming at all, you've added a cool new feature to your application.

I am arriving at completion on a multithreaded concurrency framework designed for high-performance computing. Though I am not a gamer, it has occurred to me that this stand-alone software core could be an ideal basis for a multiprocessor game engine (64-bit native C++, 5000+ entry points). Are there any websites I could visit to discuss this technology with programmers and developers who could really benefit from it?

A google scholar search turns up numerous papers on testability, including models for computing testability, recommendations for how ones code can be more testable, etc.
They all come with the assertion that more testable code is more stable, but I can't find any studies which actually demonstrate this.
Can someone link me to a study evaluating the effect of testable code vs. quality? The closest I can find is Improving the Testability of Object Oriented Systems, which discusses the relationship between design flaws and testability.
I'm currently developing a replication system to keep data in-synch between an arbitrary number of servers.
Some of these servers exist in one cluster on one LAN. Others exist somewhere else in the world.
I'm wondering what are the pros/cons of different paths that we choose to flow replicated data on between servers?
In other words, what are the different strategies to load balance the replication process ?
