Linux at 25 PETERHISTORY H
Linux at 25 PETERHISTORY H. SALUS Peter H. Salus is the author of A n June 1991, at the USENIX conference in Nashville, BSD NET-2 was Quarter Century of UNIX (1994), announced. Two months later, on August 25, Linus Torvalds announced Casting the Net (1995), and The his new operating system on comp.os.minix. Today, Android, Google’s Daemon, the Gnu and the Penguin I (2008). [email protected] version of Linux, is used on over two billion smartphones and other appli- ances. In this article, I provide some history about the early years of Linux. Linus was born into the Swedish minority of Finland (about 5% of the five million Finns). He was a “math guy” throughout his schooling. Early on, he “inherited” a Commodore VIC- 20 (released in June 1980) from his grandfather; in 1987 he spent his savings on a Sinclair QL (released in January 1984, the “Quantum Leap,” with a Motorola 68008 running at 7.5 MHz and 128 kB of RAM, was intended for small businesses and the serious hobbyist). It ran Q-DOS, and it was what got Linus involved: One of the things I hated about the QL was that it had a read-only operating system. You couldn’t change things ... I bought a new assembler ... and an editor.... Both ... worked fine, but they were on the microdrives and couldn’t be put on the EEPROM. So I wrote my own editor and assembler and used them for all my programming. Both were written in assembly language, which is incredibly stupid by today’s standards. -

The Center for the Public Domain: a Short-Lived Venture Philanthropy
Center for Strategic Philanthropy and Civil Society Teaching Case Revised: January 18, 2007 The Center for the Public Domain: A Short-Lived Venture Philanthropy “If we could find a champion for whatever initiative it was that we wanted to support, then, because we were much more lithe and less cumbersome than some big organizations, we could invest in that champion. If we found a startup, we started it. If we found a supporter, we supported it. My strength was in finding the champion, and Bob’s 1 strength was in trusting me that I was right.” —Laurie Racine, president of the Center for the Public Domain RED HAT, INC. Bob Young A native of Ancaster, Ontario, Canada, Robert “Bob” Young earned a degree in history from the University of Toronto in 1976. While in college, he encountered the work of the seventeenth- century Scottish philosopher Adam Smith. In a 2007 interview, Young outlined how Smith’s thinking had influenced his own: Going back to university days, I’ve greatly admired Adam Smith, because he was able to articulate the value in a free-market democracy of what entrepreneurial businessmen actually did. In a free-market democracy, the citizen and the consumer are the same person. You can solve problems by marching on Washington—or, in Adam Smith’s day, by marching on Whitehall—or you can solve the same problem in the marketplace. Given that the private sector accounts for eighty percent of our economy, successful businessmen arguably have every bit as much influence on our society as George Bush or Bill Clinton has. -
Linux Distributions
Linux Distributions A history and overview Neal Gompa 1 Who am I? • Professional technologist Linux user for Contact Points nearly fifteen years • Twitter: @Det_Conan_Kudo • Contributor and developer in Fedora, • Email: [email protected] Mageia, openSUSE, and OpenMandriva Linux distributions • Contributor to RPM, DNF, and various related projects • DevOps Engineer at Datto, Inc. 2 History of Linux Distributions 3 Some history on Linux and GNU... ● In 1984, Richard Stallman began development on reimplementing core components that made up Unix systems under the GNU Project (GNU being a recursive acronym meaning GNU’s not Unix) ● By the early 90s, most of the components that make up the core (user/admin tools, compiler framework, editors, etc.) were ready for use. However, the hardware management and kernel framework (GNU HURD) was largely incomplete. ● In 1991, Linus Torvalds released the first version of the Linux kernel after being frustrated with the restrictions imposed by the MINIX operating system license. In part because he wanted to learn about building an operating system on IBM PCs, he used the MINIX environment to build the first kernel, and then replaced the MINIX components with GNU ones to put together a functional system for development. ● Within a year, it was quickly discovered that having to pull components and assembling them manually was unsustainable to make a Linux-based environment useful. 4 Thus, the first distributions arrived... ● The Softlanding Linux System (SLS) was the first, released in 1992. It provided a comprehensive collection of software to make a usable Linux system. The only other thing to note was that it was quite buggy and difficult to set up. -
