How Free Become Open and Everything Else Under the Sun
This article was published as the featured article in the Journal Media/Culture here: http://journal.media-culture.org.au/0406/02_Coleman-Hill.php How Free Become Open and Everything Else Under the Sun Biella Coleman and Benjamin Mako Hill Abstract: Free and Open Source Software (FOSS) has been adopted as a political tool by leftist activists. At the same time, it has been embraced by large corporations to extend profits and has been criticized as an integral force in late capitalism. It has been adopted by members of the growing Commons movement as a model for limiting the power of capitalism. This essay attempts to confront the variability of these relationships through a cursory analysis of each field and through an look at FOSS philosophy and practice. It argues that Free Software exists as a politically agnostic field of practice--built on and through a broadly defined philosophy. It analyzes the way that this philosophy is well suited for the spread of FOSS technologies and its translation into the terms of radically different, even oppositional, social and political movements. Author Bios and Contact Information Benjamin "Mako" Hill is a Free and Open Source Software developer and advocate. He is a director of Software in the Public Interest and a member of the Debian project -- by most accounts the single largest Free Software project. In addition to volunteer and professional Free Software work, Hill writes and speaks extensively on issues of free software, intellectual property, collaboration, and technology. email: [email protected] Biella Coleman is a cultural anthropologist from the University of Chicago currently writing her dissertation on the ethical dynamics and political implications of the Free and Open Source movement. -

Introduction to Linux
Presentation to U3A - Linux Introduction 8 June 2019 – Terry Schuster - [email protected] What is Linux? https://en.wikipedia.org/wiki/Linux https://www.iotforall.com/linux-operating-system-iot-devices/ In simple terms, Linux is an operating system which was developed to be a home-built version of UNIX, one of the first operating systems which could be run on different brands of mainframe computers with quite different types of hardware. Linux has developed to the extent that it is the leading operating system on servers and other big iron systems such as mainframe computers, and the only OS used on TOP500 supercomputers (since November 2017, having gradually eliminated all competitors). It is used by around 2.3 percent of desktop computers. The Chromebook, which runs the Linux kernel-based Chrome OS, dominates the US K–12 education market. In the mid 2000’s, Linux was quickly seen as a good building block for smartphones, as it provided an out- of-the-box modern, full-featured Operating System with very good device driver support, and that was considered both scalable for the new generation of devices and had the added benefit of being royalty free. It is now becoming very common in IoT devices, such as smart watches/refrigerators, home controllers, etc. etc. BTW, Tux is a penguin character and the official brand character of the Linux kernel. Originally created as an entry to a Linux logo competition, Tux is the most commonly used icon for Linux, although different Linux distributions depict Tux in various styles. The character is used in many other Linux programs and as a general symbol of Linux. -

The LibreOffice package is built to be Package managers are a very important part of Linux distributions compatible with every user interface framework, hence heavier but we have noticed two weaknesses in them: They use pre-built than necessary: only one framework will be used for this software packages that are not optimised for specific hardware and often installation. they are too heavy for a specific need, or packages may require To optimise configuration and installation performance, source- plenty of time and resources to be compiled. In this paper, we based Linux distributions are used, one of the most famous being present a novel Linux package manager which uses cloud Gentoo Linux. computing features to compile and distribute Linux packages without impacting the end user's performance. We also show how Gentoo's package manager (Portage) builds packages from source Portage, Gentoo's package manager can be optimised for code and allows for specific compilation flags. This feature allows customisation and performance, along with the cloud computing to have packages that are optimised for a specific hardware. features to compile Linux packages more efficiently. All of this Portage also allows to build and install packages for specific resulting in a new cloud-based Linux package manager that is system requirements, with the help of USE flags [4]. -

Praise for the Official Ubuntu Book
Praise for The Official Ubuntu Book “The Official Ubuntu Book is a great way to get you started with Ubuntu, giving you enough information to be productive without overloading you.” —John Stevenson, DZone Book Reviewer “OUB is one of the best books I’ve seen for beginners.” —Bill Blinn, TechByter Worldwide “This book is the perfect companion for users new to Linux and Ubuntu. It covers the basics in a concise and well-organized manner. General use is covered separately from troubleshooting and error-handling, making the book well-suited both for the beginner as well as the user that needs extended help.” —Thomas Petrucha, Austria Ubuntu User Group “I have recommended this book to several users who I instruct regularly on the use of Ubuntu. All of them have been satisfied with their purchase and have even been able to use it to help them in their journey along the way.” —Chris Crisafulli, Ubuntu LoCo Council, Florida Local Community Team “This text demystifies a very powerful Linux operating system . in just a few weeks of having it, I’ve used it as a quick reference a half dozen times, which saved me the time I would have spent scouring the Ubuntu forums online.” —Darren Frey, Member, Houston Local User Group This page intentionally left blank The Official Ubuntu Book Sixth Edition This page intentionally left blank The Official Ubuntu Book Sixth Edition Benjamin Mako Hill Matthew Helmke Amber Graner Corey Burger With Jonathan Jesse, Kyle Rankin, and Jono Bacon Upper Saddle River, NJ • Boston • Indianapolis • San Francisco New York • Toronto • Montreal • London • Munich • Paris • Madrid Capetown • Sydney • Tokyo • Singapore • Mexico City Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. -

The games I Macintosh. So there are lots of players out there. If you play can be divided into four groups: Free Games, native don't want to play against other humans, then Freeciv linux commercial games, Windows Emulated games, and includes some nasty AIs. Win4Lin enabled games. This presentation will demonstrate games from each of these four groups. BZFlag Platform BZFlag is a tank combat game along the same lines as the old BattleZone game. Like FreeCiv, BZFlag uses a client/ Before I get started, a little bit about my setup so you can server architecture over TCP/IP networks. Unlike FreeCiv, relate this to whatever you are running.
