Comments: Linux : Articles : If I could re-write Linux By Prakash Advani Posted: ( Sun 8th Feb 2004 01:14:20[PM] UTC If we were to re-write Linux, taking clues from various operating systems, what would we make sure it did? Our next-generation operating system (NGOS) would be completely modular in design, aimed at 64-bit hardware, and with an interface that would change the way people compute. It would support a large number of applications and hardware devices, accepting device drivers written for other operating system, and run applications written for other operating system under an emulation mode.

CVS Write Access Resources Bochs History Bochs Links Related Links Screen Shots Welcome to the Bochs IA-32 Emulator Project Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, Bochs can be compiled to emulate a 386, 486, Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE, SSE2 and 3DNow instructions. Bochs can be compiled and used in a variety of modes, some which are still in development. The 'typical' use of bochs is to provide complete x86 PC emulation, including the x86 processor, hardware devices, and memory. This allows you to run OS's and software within the emulator on your workstation, much like you have a machine inside of a machine. For instance, let's say your workstation is a Unix/X11 workstation, but you want to run Win'95 applications. Bochs will allow you to run Win 95 and associated software on your Unix/X11 workstation, displaying a window on your workstation, simulating a monitor on a PC.

27. The Creation Of The UNIX* Operating System computer operating system from Bell Labs is still regarded as one of the most powerful, versatile, and flexible operating systems (OS) in the computer world. http://www.bell-labs.com/history/unix/

The Creation of the UNIX Operating System After three decades of use, the UNIX* computer operating system from Bell Labs is still regarded as one of the most powerful, versatile, and flexible operating systems (OS) in the computer world. Its popularity is due to many factors, including its ability to run a wide variety of machines, from micros to supercomputers, and its portability all of which led to its adoption by many manufacturers. Like another legendary creature whose name also ends in 'x,' UNIX rose from the ashes of a multi-organizational effort in the early 1960s to develop a dependable timesharing operating system. The joint effort was not successful, but a few survivors from Bell Labs tried again, and what followed was a system that offers its users a work environment that has been described as "of unusual simplicity, power, and elegance...." The system also fostered a distinctive approach to software design solving a problem by interconnecting simpler tools, rather than creating large monolithic application programs. Its development and evolution led to a new philosophy of computing, and it has been a never-ending source of both challenges and joy to programmers around the world.

28. C R Y P T O N O M I C O N A history of operating systems, by Neal Stephenson. http://www.cryptonomicon.com/beginning.html

NOW AVAILABLE IN TRADE PAPERBACK WHEREVER BOOKS ARE SOLD! In the Beginning was the Command Line by Neal Stephenson About twenty years ago Jobs and Wozniak, the founders of Apple, came up with the very strange idea of selling information processing machines for use in the home. The business took off, and its founders made a lot of money and received the credit they deserved for being daring visionaries. But around the same time, Bill Gates and Paul Allen came up with an idea even stranger and more fantastical: selling computer operating systems . This was much weirder than the idea of Jobs and Wozniak. A computer at least had some sort of physical reality to it. It came in a box, you could open it up and plug it in and watch lights blink. An operating system had no tangible incarnation at all. It arrived on a disk, of course, but the disk was, in effect, nothing more than the box that the OS came in. The product itself was a very long string of ones and zeroes that, when properly installed and coddled, gave you the ability to manipulate other very long strings of ones and zeroes. Even those few who actually understood what a computer operating system was were apt to think of it as a fantastically arcane engineering prodigy, like a breeder reactor or a U-2 spy plane, and not something that could ever be (in the parlance of high-tech) "productized."

Projects IRIS Chord RON ... LAB FOR COMPUTER SCIENCE We build and investigate software systems for parallel and distributed environments. We have conducted research in operating systems, networking, mobile computing, language design, compiler design, and architecture, taking a pragmatic approach: we build high-performance, reliable, and working systems. Our most recent research focuses on very large scale distributed systems based on distributed hash tables, such as Chord . The IRIS project is a large, ongoing collaboration. See the IRIS Page for more details. In general, our research focuses on extensible and flexible system services: filesystems, networking, and languages. Click is a flexible, modular router that runs on commodity hardware. SFS , the Self-Certifying File System, creates a global, secure filesystem with a single global namespace and no centralized control. `C (tick-C) is a superset of the ANSI C language with extensions for dynamic code generation. New algorithms in the `C compiler result in fast and high-quality runtime compilation. The Prolac language aims to make network protocol implementations both readable and efficient.

MINIX INFORMATION SHEET WHAT IS MINIX MINIX FEATURES HARDWARE REQUIRED PARTIAL LIST OF UTILITIES INCLUDED IN MINIX ... OTHER INFORMATION RESOURCES ABOUT MINIX WHAT IS MINIX 2.0 MINIX is a free UNIX clone that is available with all the source code. Due to its small size, microkernel-based design, and ample documentation, it is well suited to people who want to run a UNIX-like system on their personal computer and learn about how such systems work inside. It is quite feasible for a person unfamiliar with operating system internals to understand nearly the entire system with a few months of use and study. MINIX has evolved over the years, so several versions exist. Two of these are still current. The rest are obsolete. The current versions are: MINIX 2.0 (Intel CPUs from 8088 to Pentium) MINIX 1.5 (Intel, Macintosh, Amiga, Atari, SPARC) MINIX FAQs exist for both IBM PC hardware and Macintoshes. MINIX 2.0 can be compiled in either 16-bit mode or 32-mode, depending on compile time flags. For 32-bit mode, a 386, 486, or Pentium is required. MINIX 2.0 FEATURES
