Smart Electronic Sportswear Being Developed by MC10 and Reebok
Stretchable silicon electronics that offer the computing power of rigid chips could make their way into Reebok’s athletic apparel shortly. The company and MC10, a start up maker of flexible electronics, are working together to develop sportswear that incorporates electronics to monitor athletes’ health and performance during training and rehabilitation.

INS2: Australia develops first smartchip for pain
The Implantable Neuro Sensing and Stimulation (INS2) device is considered the first miniature smartchip for treating chronic pain. Its very small size, along with other key features, allows the smartchip to manage pain better in humans.
Why the new JavaFX makes sense
Myriad Sues Sun, Now Oracle, over Java
Apache leaves the JCP, what’s next?
By default websphere application server (WAS) 6.1 (maybe 6.x) has the J2EE filters disabled.
Don’t know why. Don’t ask it to me. I only know that the custom rewrite/redirect I made in my J2EE filter didn’t work until I told middleware office to set a websphere custom property.
The property to set is com.ibm.ws.webcontainer.invokefilterscompatibility and has to be set to true. You can find where to set it under the websphere administration console following this path Application Servers -> <server> -> Web Container Settings -> Web Container -> Custom Properties.
Easy once you know what to do. 🙂

Starting JBoss (5.1.x) from eclipse (3.5.x) it could happen that you get an exception like the following:
15:26:51,530 ERROR [Naming] Could not start on port 1099
java.net.BindException: Address already in use: JVM_Bind
at java.net.PlainSocketImpl.socketBind(Native Method)
at java.net.PlainSocketImpl.bind(Unknown Source)
at java.net.ServerSocket.bind(Unknown Source)
at java.net.ServerSocket.<init>(Unknown Source)
at javax.net.DefaultServerSocketFactory.createServerSocket(Unknown Source)
It’s because you have a port already in use. In this case it the port used for Naming service. While changing port from the eclipse editor didn’t work, you can (after stopping the server), open the file
search for the desired port (in this case 1099) and then change it to a new value (in my case 1199 was free).
<!-- Naming Service -->
<property name="description">The listening socket for the Naming service</property>
save and start the server.
