When attempting to burn a DVD tonight I was getting a message from within the OSX Disk Utility stating that the Disc Drive was busy. At first I thought it must be a DVD that was not compatible with the DVD burner however I attempted to use three different types of DVD’s with the same message. Finally I realized that I had VMWare Fusion running and one of the VM’s I was using at the time was sharing the Disc Drive with the host OS or OSX. Below are more details about what the message from the OSX Disk Utility will look like and how to remove the disc drive from being shared with a VMWare image.
Last night I was working on upgrading the BIOS on an older Dell Poweredge 650 that I have been using as a PostgreSQL development server. One of the CD’s I needed to create is downloaded from Dell as two parts of an ISO file that needed to be combined so below is information on how to combine the files using the Windows copy command.
Yesterday we had to upgrade a Ubuntu Linux server from a really old version of Ubuntu to the latest and greatest version of Ubuntu.

Alex and I got some new laptops the other day. I have been a Linux user primarily for many years but the laptop came with Windows 7 so I decided to give it a spin. I must say on the whole I have to say it is a very fast and usable operating system. There is just one thing I was missing and that was Linux shell commands in the terminal. Nothing fancy but I am so used to using ls,rm and grep that I almost went back to Linux. But then Alex mentioned something about adding Cygwin to his laptop which I am of course familiar with but he also mumbled about adding it to the path. I had never even considered this, so I did it and wow is it cool. All the commands I love are in my terminal now. Plus if you use console.exe you can have tabs and every thing.
Earlier when attempting to install the request-log-analyzer gem on a CentOS Linux server I ran into some issues. I noticed that on one server I was able to install the request-log-analyzer gem without issue but on another server running the same version of CentOS and Ruby as the first server the attempt to install request-log-analyzer returned an error. The error was that the gem required a newer version of another gem.
