Hover your mouse over the numbers for more detailed descriptions. In all, Web VMStat is a simple way to keep an eye on servers on your network without having to log in to them. You could create a bookmark group for a bunch of machines, for instance, and open them up in tabs for a quick glance of how they’re performing. And all the information is gathered by the ‘real’ vmstat tool, With Web VMStat, so you know it’s legit. resource usage is shown in a much clearer and prettier manager.

  • Open Thesis Final.Pdf
    The Pennsylvania State University The Graduate School College of Communications EVALUATIO OF FOSS VIDEO GAMES I COMPARISO TO THEIR COMMERCIAL COUTERPARTS A Thesis in Media Studies By Jesse A. Clark © 2008 Jesse A. Clark Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Arts August 2008 ii The thesis of Jesse A. Clark was reviewed and approved* by the following:: John Nichols Professor of Communications Associate Dean for Graduate Studies and Research Matt Jackson Associate Professor of Communications Head of Department of Telecommunications Thesis Advisor Robert Frieden Professor; Pioneers Chair in Telecommunications Ronald Bettig Associate Professor of Communications *Signatures are on file in the Graduate School. iii Abstract The topic of copyrights and copyright law is a crucial component in understanding today's media landscape. The purpose for having a copyright system as outlined in the U.S. Constitution is to provide content creators with an incentive to create. The copyright system allows revenue to be generated through sales of copies of works; thus allowing for works to be created which otherwise would not be created. Yet it is entirely possible that not all large creative projects require the same legal framework as an incentive. The so called “copyleft” movement (which will be defined and explained in depth later) offers an alternative to the industrial mode of cultural production. Superficially, “copylefted” works can be divided into two broad categories: artistic/creative works (which are often protected by “Creative Commons” licenses), and Free/Open Source Software. This thesis evaluates how open source video games compare to their commercial counterparts and discusses the reasons for any difference in overall quality.
