As my readers know, I use Windows because many legal specific software applications require it. My true love, however, is Ubuntu Linux, which is completely free and open source. She Who Must Be Obeyed is setting up a computer lab at her school, and education, security, and cost are all important factors. So, I am downloading the Educational package add-on for Ubuntu, and will be installing Ubuntu with it on all the school computers. This software is spreading over the entire world, and brings the security of Linux, educational software without parallel, and free and open source computing, to students and teachers everywhere. Losing a few billable hours today - $2,000. Spending time installing Ubuntu Linux at my kids' school - priceless.
