L L3/L4 
L3 is a microkernel running on i386, i486 and Pentium processors which has been developed by Jochen Liedtke and others at GMD's SET institute. Supported at TU-Dresden

Its predecessor was Eumel

L4 is a successor to L3. The Intel versions (for i486 and the various Pentiums) have been developed by Jochen Liedtke at GMD and IBM Watson Research Center, and there also exist implementations for the MIPS (from UNSW) and Digital Alpha processors (from us).

Fiasco is a new, L4-compatible microkernel for x86 processors.

LindowsOS is a new, fun and exciting operating system that delivers the power, stability and cost-savings of Linux with the ease of a windows environment. LindowsOS is easy to experience because of its friendly graphical interface and support for popular Microsoft Windows file types (.doc, .xls, .ppt, .jpg, .gif, .mp3, etc.)

Though the name shell sugest a Windows clone, its just Linux in disguise. Just a different marketing style.

Group Members: Linus Torvalds and a Cast of Thousands
Linux is a freely-distributable implementation of UNIX for 80386, 80486 and Pentium machines. It supports a wide range of software, including X Windows, Emacs, TCP/IP networking (including SLIP/PPP/ISDN), and the works. Ports to non-x86 machines such as the Alpha and SPARC also exist. This is one rocking project.
OS-Kernel written by Linus Torvalds. 
Most other OS modules were taken from the GNU stock of Free Software (s. Richard Stallman, Linux and the GNU Project). 

In the case of Linux, the Internet community desperately needed a competent OS platform. AT&T had shut out many Unix users with restrictive licenses and high fees. UC Berkeley had crippled  BSD by removing all vendor proprietary code which adapted it to the underlying hardware: you could study it but not run it! Many saw a potential in Andy Tanenbaum's Minix to counterbalance an increasingly unfree Unix. But Minix was incomplete, did not have critical mass and its source distribution became too restrictive. These conditions inspired the community OS effort, initially derived from Minix, which produced Linux. Linux became readily available and increasingly capable. When it aligned with  FSF licensing and could support the powerful  GNU tools as well as run on a wide range of inexpensive hardware, a truly useful operating system platform was born. The Internet community finally had a way to run a fully networked Unix cheaply and reliably with no strings attached. 

"Linus Torvalds, for example, didn't actually try to write Linux from scratch. Instead, he started by reusing code and ideas from Minix, a tiny Unix-like OS for 386 machines. Eventually all the Minix code went away or was completely rewritten 
     "In fact, I think Linus's cleverest and most consequential hack was not the construction of the Linux kernel itself, but rather his invention of the Linux development model. When I expressed this opinion in his presence once, he smiled and quietly repeated something he has often said: ``I'm basically a very lazy person who likes to get credit for things other people actually do.'' Lazy like a fox. Or, as Robert Heinlein might have said, too lazy to fail. 
    "... one precedent for the methods and success of Linux can be seen in the development of the GNU Emacs Lisp library and Lisp code archives. In contrast to the cathedral-building style of the Emacs C core and most other FSF tools, the evolution of the Lisp code pool was fluid and very user-driven."

GUIs for Linux: 

KDE (build on QT Toolkit ). 
The K Desktop Environment

GNOME (GNU Network Object Model Environment) 
a Windows-like interface for Linux, created by a group of developers, that will compete with the K Desktop Environment interface. GNOME may pique IT interest, since it uses an object-oriented development environment based on Common Object Request Broker Architecture.

IBM joins Linux International 
Open source OS's momentum looks unstoppable in the server space 
Following Sun's lead, IBM Software Solutions has become a sponsoring corporate member of Linux International. Besides these two the roster now includes Silicon Graphics and Compaq. Missing for the moment is HP, though that company has recently announced that it will sell Linux on its NetServer systems and has struck an alliance with Linux packager Red Hat.

520 computers running Linux in a heterogeneous network - breaking the world record. - The Fastest Computer On Earth 
You only need to download a small client program which contacts our servers and will process part of the current challenge. We only use the computer's idle time, so when you want to use your computer, the client will automatically use less processor time until you stop working on your computer again. Challengers are RSA, who award $10000 to whoever cracks their crypto algorithms.

Linux' Mindshare Went Through The Roof: 
"Linux had no mindshare with the people who make the decisions. I think that's one of the big things that's been happening for the last three or four months is that mindshare went through the roof. ...  
     And what I think will happen is that some company -- maybe not IBM, but a company like IBM -- will just happen in the future where they're already doing multiplatform support, because everybody has it if you're in the big league. And they're just going to add Linux to the list of platforms they support. And then you're going to be able to buy one machine and Linux will be installed on it. I expect that to happen within a year.... Well, Intel surprised me by being so about-face. I had talked to Intel before, but Linux was a dirty word, and that was just a year ago. And Intel has been very positive lately, which is nice....  
     I think that there are a lot of people in Redmond scratching their heads wondering "What the hell can we do?" ... And at the same time they have a really hard time coming to grips with the fact that it's a market outside their market; one they can't direct. And that's probably why they're nervous. I don't know...I don't think they're really nervous. I think they're mildly nervous. I don't think Bill spends the nights lying there thinking about Linux."  
(Linus Torvalds interviewed by Robert McMillan, LinuxWorld, October 1998) 

"Essentially I see the Java engine just slipping, not going anywhere. And I really hate 
that happening because Java could have been a big boost to Linux. " 
(Linus Torvalds interviewed by Robert McMillan, LinuxWorld, August 1998) 

"I consider the linux copyright to be one of the very best design decisions I ever did, along with accepting code that was copyrighted by other holders (under the same copyright conditions, of course). 
I'm not fanatic about the GPL, but in the case of linux it has certainly worked out well enough."

Linux International 
Linux International is a non-profit organization, residing physically in the United States, however our organization is made up of many people contributing from all areas of the globe. We distribute information about Linux, and how it will benefit business and personal users, reserve places at major computer expos, and accept donations to distribute to programmers who need money to test out applications.

Leander Kahney: Mexican Schools Embrace Linux (Wired News, 6.Nov.98) 
"... the Mexican government said this week that it plans to install the free Linux operating system in 140,000 elementary- and middle-school computer labs around the country. ... Cost factors aside, Espinosa said Linux is more reliable, adaptable, and efficient than commercial operating system software. These qualities will allow him to use older, less expensive equipment. ... The program already has 2,000 labs set up using Windows software, but Espinosa said those schools will soon switch to Linux. ... He predicted Mexican schools will become hotbeds of Linux programmers. "It will let a lot of kids discover computers," he said. "Some may become little hackers." "

Related to: Mach
Lites is a 4.4 BSD Lite based server and emulation library that provides free unix functionality to a Mach based system. Lites provides binary compatibility with 4.4 BSD. NetBSD (0.8, 0.9, and 1.0), FreeBSD (1.1.5 and 2.0), 386BSD, UX (4.3BSD) and Linux on the i386 platform. It has also been ported to the pc532, and PA-RISC. Preliminary ports to the R3000 and Alpha processors have also been made.

Lynx (Lynx Real-time Systems)
LynxOS is a proprietary UNIX-like real-time operating system. LynxOS looks and feels like UNIX from the user/programmer point of view. It was developed from the ground-up with high performance, deterministic hard real-time response in mind. Although LynxOS is conformant with POSIX 1003.1 it is not derived from any AT&T/USL/Novell source code. The OS is in effect a complete re-implementation of UNIX from a real-time perspective.
