Sources of conflict between the two and shared values of the two are discussed in order to find some reconciliation and come to an understanding of how a shared set of ethics is possible. A reconciled set of ethics allows hackers to function within the corporate world without compromising their principles and allows the commercial world to benefit from some of the more progressive ideas within the hacker community. A reconciled set of ethics allows hackers to function within the corporate world without compromising their principles -

The document has not been submitted for qualifications at any other academic institution. Katharina Freund 30 September, 2011 i ABSTRACT This thesis documents and analyses the contemporary community of (mostly) female fan video editors, known as vidders, through a triangulated, ethnographic study. It provides historical and contextual background for the development of the vidding community, and explores the role of agency among this specialised audience community. Utilising semiotic theory, it offers a theoretical language for understanding the structure and function of remix videos. -

Hacker Culture & Politics
HACKER CULTURE & POLITICS COMS 541 (CRN 15368) 1435-1725 Department of Art History and Communication Studies McGill University Professor Gabriella Coleman Fall 2012 Arts W-220/ 14:35-17:25 Professor: Dr. Gabriella Coleman Office: Arts W-110 Office hours: Sign up sheet Tuesday 2:30-3:30 PM Phone: xxx E-mail: [email protected] OVERVIEW This course examines computer hackers to interrogate not only the ethics and technical practices of hacking, but to examine more broadly how hackers and hacking have transformed the politics of computing and the Internet more generally. We will examine how hacker values are realized and constituted by different legal, technical, and ethical activities of computer hacking—for example, free software production, cyberactivism and hactivism, cryptography, and the prankish games of hacker underground. We will pay close attention to how ethical principles are variably represented and thought of by hackers, journalists, and academics and we will use the example of hacking to address various topics on law, order, and politics on the Internet such as: free speech and censorship, privacy, security, surveillance, and intellectual property. We finish with an in-depth look at two sites of hacker and activist action: Wikileaks and Anonymous. LEARNER OBJECTIVES This will allow us to 1) demonstrate familiarity with variants of hacking 2) critically examine the multiple ways hackers draw on and reconfigure dominant ideas of property, freedom, and privacy through their diverse moral 1 codes and technical activities 3) broaden our understanding of politics of the Internet by evaluating the various political effects and ramifications of hacking. -

Gentlemen's Argument
Copyright © 2007, Chicago-Kent Journal of Intellectual Property A GENTLEMEN'S AGREEMENT ASSESSING THE GNU GENERAL PUBLIC LICENSE AND ITS ADAPTATION TO LINUx Douglas A. Hass" Introduction "Starting this Thanksgiving, I am going to write a complete Unix-compatible software system called GNU (for GNU's Not Unix), and give it away free to everyone who can use it." With his post to the Usenet 2 newsgroup net.unix-wizards, 3 Richard Stallman launched a sea change in software development. In 1983, he could not have known that his lasting contribution would not be the GNU operating system, but instead the controversial software license that he would develop as its underpinning: the GNU General Public License (GPL).4 Today, the operating system most closely associated with the GPL is Linux, developed originally by Linus Torvalds, a Finnish university student.5 Research group IDC's Quarterly Server Tracker marked Linux server revenue growth at three times Microsoft Windows server growth in the first quarter of 2006, its fifteenth consecutive quarter of double-digit revenue growth. 6 British research firm Netcraft's July 2006 Web Server Survey gives Linux-based 7 Apache Web servers the largest market share among Web servers queried in its monthly survey. With Linux gaining an increasingly larger position in these markets, the validity of the GPL takes on increasing importance as well. The open source community's commercial and non-commercial members are conducting a robust debate on the intellectual property issues surrounding the GPL and Linux, its most * Douglas A.
