Yum Warning: There Are Unfinished Transactions Remaining, You Might Consider Running Yum-Complete-Transaction First To Finish Them

During the build of a Linux development server earlier I performed a “yum update” to update all of the packages after installing CentOS 5.4. I got busy with other tasks and left the server at work without checking to verify that the update had worked properly. Now after dinner I started to get back to work on the server by installing some new packages via yum and received a yum warning message which I describe in greater detail below along with how to resolve the warning.

How To Convert .WRF Files To .WMV, AVI, MP4, XVID, or MPEG

Someone sent me a WebEx webcast they wanted me to view this afternoon. The file had a .WRF file ending which stands for WebEx Recording Format which is one of the two file formats that WebEx webcasts are saved as. The other format that WebEx files are saved as is the ARF or WebEx Advanced Recording Format. Typically you could simply download the WebEx Player available by clicking here however you may want to convert this video, which requires the WebEx Recording Editor, to provide to others in a format they can view without having to install an application. It took me awhile to figure out how to convert this file properly since I only seemed to be able to find the older WebEx Editor versions. I finally signed up for a trial account and was able to download version 3 of the WebEx Recording Editor which allowed me to convert to WMV format and from that I was able to convert to any other video format including AVI, MP4, XVID, and MPEG. Follow the directions below to first convert the .WRF to .WMV and then the second set of directions if you want to convert to another video format.

Below I describe how to turn off the Java Update Scheduler process but also how to schedule a Windows 7 task to check once a month for Java updates.

Install Backtrack 4 On Windows 7 In A Virtual Machine Using Windows Virtual PC

I have been using a Windows 7 laptop for quite awhile as my daily driver and recently wanted to install Backtrack 4 in a virtual machine so I wasn’t required to dual boot or use a different laptop for BT4. I thought about using VMware as Martin wrote an article a couple months ago about installing Backtrack in a VM on Windows 7 but a couple months ago I discovered Windows Virtual PC during a Windows XP VM install. So far I have been really happy with Windows Virtual PC and decided to try installing Backtrack 4 in a Windows Virtual PC virtual machine. Below are the details on how to setup the Windows Virtual PC virtual machine and then information on how to install Backtrack 4 in that VM.
