How to mount an ISO image file on Windows 7

There is a free unsupported utility from Microsoft ( http://www.microsoft.com/en-us/download/details.aspx?id=38780 ) called Virtual CD-ROM Control Panel that enables users of Windows XP, Windows Vista, and Windows 7 to mount ISO disk image files as virtual CD-ROM drives.

I downloaded it, unzipped, moved driver to Windows System folder, configured it and attempted to use. Finally, remove it from my test computer.

Next, go to http://www.slysoft.com/en/virtual-clonedrive.html to get SlySoft Virtual Clone Drive, a freeware. After installed it, I can open the ISO image disk file from Windows Explorer. Virtual Clone Drive is easy to install and use.

Back to School

Back to school means go to class, listen to teacher, doing homework, take the quiz or test. This time I'm back to school to learn Ruby on Rails and reinforce my knowledge in Software as A Service for free. My school here is not a normal, traditional school but an online school. I work full-time to keep a roof over my head so I prefer to study part-time at my own leisure. Spending more money to get advance degree is not my goal at this time.

The online course Software Engineering for Software as a Service taught by UC Berkeley professors Armando Fox and David Patterson. Every evening and weekend, I watched the video lectures and read the Kindle version of text book "Engineering Long-Lasting Software: An Agile Approach Using SaaS and Cloud Computing". I also did homework and submitted to grade. It was fun but not easy.

I'm really enjoy this class. I'm appreciate the professors and others made this free online course available to more than sixty thousands students. Prior to this class, I'm also follow iPad and iPhone Application Development (HD) by Stanford professor Paul Hegart in iTunes. With the current technology, we can have the best education for free. Gaining a knowledge is more important than the degree or certificate. I love to learn.
