Hi All, I'm a teacher working to establish a thin client setup in my classroom which upon success will be immediately replicated in 2 other science classrooms. While the district (Minneapolis Public Schools) is supporting my efforts, they don't know Linux so I'm on my own--with you-all as back up! My goal is create a flexible hardware/software/pedagogical model that will be replicated in all Minneapolis public schools and anyplace where the kids are economically the neediest and of course anywhere else. My blog <a href="http://groosd.blogspot">http://groosd.blogspot</a> reports the tip of the iceberg of my efforts to get this working. As a teacher properly manages computer user permissions in class, students grow in responsible use of this resource. While there are some students who follow the rules when told, others like to explore and test limits. Having a process to manage what students can do on the computers and rewarding students who use the resources responsibly, brings everyone together, allowing for a creative, collaborative and hard working classroom of adolescents. From what I've heard and read on line, there was an excellent GUI program Sabayon which was designed to do just this. Apparently this isn't being maintained and it doesn't work in Hardy or Intrepid. I've seen that some including LaserJock have worked some on this lately but don't know of status? Andreas Olsson and Jordan Mantha and others suggested making a simple script to manage group permissions, a great way to solve this need. Andreas said he would write this script in PERL (his strength) as a proof of concept as well as to meet my class' immediate need. Comments? thoughts? Thanks for all of your work; it makes my work possible. David
