OAS - The operation with name getMBeanInfo could not be found.

I saw this in the OC4J log when I stopped and started the application.  This is a false error.  When I undeployed and redeployed the app, the true error displayed in Oracle Enterprise Manager: ORA-01017: invalid username/password; logon denied.  This happened when I switched DB servers and missed updating a config value (datasource).

The death of Kodak digital
Months ago Kodak announced that it was discontinuing its digital video to focus on “significant opportunities for profitable growth”. Three years ago I picked up the little Kodak Zi6 (pronounced Zix) for the kids for Christmas. It is an HD pocket video camera with a nice 3” LCD all built into a something a bit longer than an deck of cards. It is low tech and great! The kids have had a ball with it, and for around $100 it was perfect. It comes with 2 AA rechargeable batteries and the recharger. You ......

WmiPrvSE.exe consuming 25% of CPU on Win7
On my HP laptop the WMI Provider Host was consuming 25% of my CPU. This just started one day.

To turn it off: On your desktop right-click on Computer and select Manage Select Services and Applications and double click Services Right click on the HP Wireless Assistant Service and select Properties Change the Startup Type to Manual ......

Google App Engine local running old version of code

I found starting and stopping the GAE SDK from Eclipse would sometimes not be enough for GAE to deploy a code change to a servlet.  This would occur unexpectedly, even after working form multiple code/test iterations. A recommendation I found on a Google board was to touch the appengine-web.xml file.  Which works just fine.

First look at the cloud with Google App Engine and Udacity
Udacity is free online university and offers a CS253 intro to web development class. Since I am currently a web developer/architect in ASP.Net (and recent project has brought me back to Java) it is a bit light. However, it does offer me a nice problem set and my first exposure to writing cloud apps with GAE and Google Datastore. Steve Huffman, who developed reddit, is the instructor and does offer nice real-life stories. Give it a look ......

AppleTV - itunes store is temporarily unavailable - please check back later
When attempting to rent a movie on ATV, my wife received the error message above. Alternately “server unavailable”. When your wife is sick, the amount of IT support she needs goes up exponentially. One piece of the puzzle was that she had changed her Apple ID password. On her PC I ran iTunes and under account, there was only 1 device listed (not the ATV). Even when signed out/back-in on the ATV under Settings>iTunes it still gave same error message. What I suspect is it thinks she is trying to ......
