  • The GNOME Desktop Environment

    The GNOME Desktop Environment

    The GNOME desktop environment Miguel de Icaza ([email protected]) Instituto de Ciencias Nucleares, UNAM Elliot Lee ([email protected]) Federico Mena ([email protected]) Instituto de Ciencias Nucleares, UNAM Tom Tromey ([email protected]) April 27, 1998 Abstract We present an overview of the free GNU Network Object Model Environment (GNOME). GNOME is a suite of X11 GUI applications that provides joy to users and hackers alike. It has been designed for extensibility and automation by using CORBA and scripting languages throughout the code. GNOME is licensed under the terms of the GNU GPL and the GNU LGPL and has been developed on the Internet by a loosely-coupled team of programmers. 1 Motivation Free operating systems1 are excellent at providing server-class services, and so are often the ideal choice for a server machine. However, the lack of a consistent user interface and of consumer-targeted applications has prevented free operating systems from reaching the vast majority of users — the desktop users. As such, the benefits of free software have only been enjoyed by the technically savvy computer user community. Most users are still locked into proprietary solutions for their desktop environments. By using GNOME, free operating systems will have a complete, user-friendly desktop which will provide users with powerful and easy-to-use graphical applications. Many people have suggested that the cause for the lack of free user-oriented appli- cations is that these do not provide enough excitement to hackers, as opposed to system- level programming. Since most of the GNOME code had to be written by hackers, we kept them happy: the magic recipe here is to design GNOME around an adrenaline response by trying to use exciting models and ideas in the applications.

    1 of 10 For Australian Computers in Education Conference (Draft of 3rd of March 2000) FreeBSD and Linux: What they Can Do for Schools Edward Irvine Forster High School1, NSW [email protected] About the Author. Edward Irvine has worked as a dishwasher, deck-hand, tree planter and design engineer. For the last seven years he has been a teacher in NSW state schools. He is a Microsoft Certified Professional and is working his way towards becoming a Microsoft Certified Systems Engineer. Ed has used Unix on and off since 1986. His home page is at http://www1.tpgi.com.au/users/eirvine 2 of 10 For Australian Computers in Education Conference (Draft of 3rd of March 2000) Abstract Free UNIX-compatible operating systems such as FreeBSD and Linux can be of enormous benefit to schools. These operating systems have an established place as servers in the IT industry. While their traditional role has been in Internet infrastructure, they are also being used to replace Novell and Microsoft file servers. Recent developments in graphical user interfaces now make them a viable proposition for the desktop. Surprisingly, price may not be the only benefit to schools: an educational computing environment may actually favour using a UNIX-compatible operating system instead of Windows or Mac OS. 3 of 10 For Australian Computers in Education Conference (Draft of 3rd of March 2000) Introduction: FreeBSD and Linux This paper will discuss the suitability and benefits of installing FreeBSD or Linux as a server or desktop operating system at your school. Microsoft2 Windows, Novell NetWare, FreeBSD and Linux are computer operating systems.

    The Internet Is a Semicommons

    GRIMMELMANN_10_04_29_APPROVED_PAGINATED 4/29/2010 11:26 PM THE INTERNET IS A SEMICOMMONS James Grimmelmann* I. INTRODUCTION As my contribution to this Symposium on David Post’s In Search of Jefferson’s Moose1 and Jonathan Zittrain’s The Future of the Internet,2 I’d like to take up a question with which both books are obsessed: what makes the Internet work? Post’s answer is that the Internet is uniquely Jeffersonian; it embodies a civic ideal of bottom-up democracy3 and an intellectual ideal of generous curiosity.4 Zittrain’s answer is that the Internet is uniquely generative; it enables its users to experiment with new uses and then share their innovations with each other.5 Both books tell a story about how the combination of individual freedom and a cooperative ethos have driven the Internet’s astonishing growth. In that spirit, I’d like to suggest a third reason that the Internet works: it gets the property boundaries right. Specifically, I see the Internet as a particularly striking example of what property theorist Henry Smith has named a semicommons.6 It mixes private property in individual computers and network links with a commons in the communications that flow * Associate Professor, New York Law School.
