Minix on the iPod: where Linux started


Microkernels Address the OS Softspots on Your Network

,----[ Quote ]
| Right now Tanenbaum can point to Minix 3 -- the latest version of Minix. This
| has a microkernel of just 5,000 lines of code running in kernel mode -- less
| than 0.1% of the size of the Windows kernel. Device drivers run above the
| kernel in user mode, each one running as a separate process and restricted to
| accessing only its own memory. He points out that with just 5,000 lines of
| code there may be fewer than 100 bugs in the kernel, which could slowly be
| found and eliminated. In fact there could be far fewer: he says drivers
| typically have between 3 and 7 times as many bugs per 1,000 lines of code as
| the rest of the system. By removing the drivers from kernel space the most
| buggy kernel code is removed.
| Tanenbaum is currently embarking on a project to produce a stable and secure
| operating system based on a similar microkernel architecture, which he
| intends to design with a POSIX interface (perhaps extended with Linux system
| calls) so that it will run UNIX (and Linux) software "without too much
| effort." (An alternative approach is to run a hypervisor in kernel mode,
| emulating a virtual machine running its own OS in user mode. But as operating
| systems are often paravirtualized to run in these virtual machines, and the
| hypervisor is adapted with an extensive API to provide services to the
| virtual machines, the distinction between a hypervisor and a microkernel
| becomes blurred, he says.)


EU funds research on lightweight, stable open-source OS

,----[ Quote ]
| The European Research Council has granted â2.5 million (around US$3.3
| million) to a Dutch university for its research on a "more reliable and
| secure" Unix-type operating system. The research team seeks to top todayÂs
| popular operating systems in the market, such as Windows and Linux,
| particularly in security features.


Europe Funds Secure Operating System Research

,----[ Quote ]
| A Dutch university has landed a European Research Council grant to continue
| work on a Unix-type operating system that aims to be more reliable and secure
| than Linux or Microsoft Windows.
| The â2.5 million (US$3.3 million) grant will fund three researchers and two
| programmers, said Andrew S. Tanenbaum, a computer science professor at Vrije
| Universiteit in the Netherlands.


Andrew Tanenbaum presents Minix 3 at FrOSCon

,----[ Quote ]
| Tanenbaum became known in the 1980s with Minix, an operating system he
| designed for educational purposes. Unlike the original Minix, which was
| intended only to demonstrate the principles behind operating systems, Minix 3
| has been designed to be a productive and useful system.


[1992:] LINUX is obsolete

,----[ Quote ]
| Don`t get me wrong, I am not unhappy with LINUX.  It will get all the people
| who want to turn MINIX in BSD UNIX off my back.  But in all honesty, I would
| suggest that people who want a **MODERN** "free" OS look around for a
| microkernel-based, portable OS, like maybe GNU or something like that.


MINIX 3 and Sound Card Buzz!

,----[ Quote ]
| MINIX has been around for a while now, and to all of those who think that
| Linux is better, just remember this: MINIX is older than Linux! In fact,
| Linus Torvalds (creator of Linux) used MINIX as inspiration and a guide
| when writing Linux.
| If you are interested in MINIX, and don't feel like dual-booting or
| getting rid of your current operating system, MINIX can be run on a
| virtual machine. See http://www.minix3.org/doc/faq.html#simulators for
| more details!



DIY CPU demo'd running Minix

,----[ Quote ]
| Bill Buzbee offered the first public demonstration of the Minix OS -- a
| cousin of Linux -- running on his homebrew minicomputer, today at the Vintage
| Computer Festival in Mountain View, Calif. Magic-1, built with 74-series TTL
| ICs using wire-wrap construction, implements a homebrew, 8086-like ISA.


Interview with Dr Andrew S Tanenbaum

,----[ Quote ]
| Andrew S Tanenbaum: A couple of years ago this guy called Ken Brown
| wrote a book saying that Linus stole Linux from me, from Minix,
| and therefore the intellectual property rights are unclear and
| therefore companies shouldn't use Linux because I might sue them.
| It later came out that Microsoft had paid him to do this --
| and I defended Linus. I wrote on my Web site saying that this
| guy Brown came through, visited me and I gave him the
| [correct] story.


Debian GNU/Minix

,----[ Quote ]
| Finally someone has seen the light and started a project that I called for in
| a previous article. This melding of the Minix kernel with the GNU userland is
| called Preventa, and seems to poke fun at the name Nexenta, a similar project
| using the Solaris kernel, all in good fun Iâm sure, considering that the
| project leaderâs blog is called âLa Salle Debainâ (a play on âDebianâ and the
| French for âbathroomâ).


Minix 3.1.3

,----[ Quote ]
| This isn't Ubuntu Linux, or even Linux at all, and it shows. That's
| not necessarily a bad thing, but you need to know what you're
| getting into.


Release Notes of MINIX 3.1.3 - Developer's Interim Release

,----[ Quote ]
| MINIX 3.1.3 was released friday, april 13th 2007. It is not a full-quality,
| stable release but a work-in-progress interim release.


Review of Minix 3.1.2a IDE build2

,----[ Quote ]
| There has been some controversy regarding the intertwined histories
| of Linux and Minix. It's true that Linus Torvalds used Minix and the
| first versions of Linux required a Minix system to boot from.
| [...]
| The overall feel of Minix is super lightweight and fast. It reminds
| me of older Unix systems with the behaviour of some of the
| system tools.


MINIX: what is it, and why is it still relevant?

,----[ Quote ]
| MINIX, as originated by Andy Tanenbaum, is an operating system that
| has its roots and heart in academia as a tool that teaches you how
| kernels really should work. Recently, however, with the advent of
| version three of this rock solid OS, the focus is on making a
| production ripe embedded distribution.


Comparing Linux and Minix

,----[ Quote ]
| The UnixBench results (raw results: Minix, Linux) paint a rather
| different picture. These results are summarized in the plot to the
| left; the upper bar for each test represents Linux. The measured
| system call overhead for Minix is a full ten times higher than
| the value for Linux. The file copy tests ran between two and ten
| times faster on Linux. Pipe throughput differed by a factor of
| seven; Minix was 140 times slower at process creation. The
| difference in shell script execution performance, however, was
| 1.4 - in Minix's favor. One assumes that the rather simple shell
| provided by Minix is, at least, faster than bash.


Tanenbaum outlines his vision for a grandma-proof OS

,----[ Quote ]
| Software today is blighted by being too bloated, says Andrew Tanenbaum
| [...]
| "Maybe the direction Linux could go would be [as] the system that is
| ultra reliable, that works all the time and has not got all the
| problems that you get in Windows," he suggested.


Andrew Tanenbaum: Operating systems' Mr Reliable

,----[ Quote ]
| Almost 20 years on, what would you say has been MINIX's
| contribution to society?
| Well, it has educated hundreds of thousands of students worldwide
| in operating system design. It also led to Linux. I doubt that
| Linus would have written Linux if he hadn't had the MINIX source
| code to study carefully. I think that it will yet show that the
| only way to make a system truly reliable is to make it small
| and modular.
