Several students in our PHP/mySQL class have asked about installing Netbeans IDE and/or Sublime-Text editor in their CentOS6 virtual servers. After researching the installation instructions for these programs, I determined that there was no one place that explained what our students were looking for. Therefore, I am going to provide an installation guide here. Continue reading “How To Install Netbeans with JDK Bundle and Sublime-Text in CentOS6 and RHEL6“
I am a bit OCD when it comes to time. I always have clocks around me. I especially like atomic clocks that synchronize with www.time.gov in Boulder, Colorado.
Back in 2003, our local Walgreens ran a special on atomic clocks for about $20.00 each. At that time atomic clocks were not as easy to find as they are now (just research them on amazon.com and see how many come up). I ended up buying two of these clocks – Model #701070 Item #C17D1775.

Log in as root and enter the following line of code:
gconftool-2 --direct --config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults --type bool --set /apps/gdm/simple-greeter/disable_user_list true
Either reboot your server or log out and then log back in to check your fix.
As a budget cutback, our school administrators asked us to shutdown all non-essential classroom computers at night to save electricity. I teach Linux in a classroom that has a Dell Poweredge 2850 Red Hat Enterprise Linux (RHEL5) server and 29 Dell Optiplex 745 student lab computers running Microsoft Windows XP SP3 as the host operating system and VMWare Server to provide virtual Linux machines for our classes. I researched on the Internet for the best solution to remotely shutdown the student lab computers at night. I was not able to find one post or how-to that completely answered my questions, but I was able to piece together a solution. In an effort to document this project and help others with similar needs, here are my notes on the project. Continue reading “How To Remotely Shutdown Windows XP Computers from a Linux Server“
The Information Technology Departments in the Business/Public Service Division at Greenville Technical College where I teach subscribe to the MSDN Academic Alliance which provides our students and faculty free download versions of select Microsoft products. Starting in September 2009, we were able to download either the 32-bit or 64-bit versions of Windows 7 Professional. Jumping on the opportunity to install Microsoft’s latest operating system and move from 32-bit to a 64-bit data path, the week of October 12, 2009 I began migrating from Windows XP Professional Service Pack 3 to the new Windows 7 Professional.
