Accepted GSOC students have started the bonding period - 28 Apr 2011

After a careful selection process, we have selected 4 great students to do their GSOC projects with us. For a list and status overview, see the GSOC2011 wiki page.

The community bonding period has begun, coding starts may 23rd.

So, everyone enjoy getting to know each other :)

Minix3 accepted to GSOC! - 19 Mar 2011

Great news. See this link. for the discussion thread.

3.1.8 is here! - 04 Oct 2010

3.1.8 is released! See the download page, and for more release info. The announcement is here.

3.1.7 is here! - 16 Jun 2010

3.1.7 is released! See the download page, and for more release info.

Accepted GSOC 2010 students - 26 Apr 2010

We have fortunate with the applications of many talented students, and the generosity of Google in assigning us 4 slots that we could use to hire students. After a process of reviewing and providing feedback on the student proposals, evaluating their work, and doing interviews, we have selected the four students whose proposals we found most suitable, and Google has just confirmed all project student selections, so we are free to announce them.

The four accepted GSOC 2010 students, projects and mentors are:

  • Thomas Cort - Unix Domain Sockets
    Thomas is going to be mentored by Thomas Veerman (yep, two Thomases!) in implementing unix domain socket support for Minix. This is a valuable addition to Minix, as it's often a sticking point for porting applications.
  • Gautam Buccapatnam Tirumala - pkgsrc
    Gautam is going to be mentored by Arun Thomas and Ben Gras in porting NetBSD's pkgsrc portable package porting infrastructure to Minix, finally giving Minix a mature package management system, and probably many more ported packages out of the box to boot.
  • Feiran Zheng - multiboot
    Feiran will be mentored by Erik van der Kouwe, and will work on making Minix multiboot compliant. This means Minix will no longer depend on its own boot monitor in order to boot, circumventing boot monitor limitations where necessary, being more grub-friendly, and most likely smoothing the path for booting on an embedded system in the future.
  • Stefano Cordio - firewall
    Stefano will be mentored by Cristiano Giuffrida, and will implement or port a modern firewall / packet filter in Minix' inet server.
We're very happy with the selection, and remembering last years' successful GSOC, we want this years' to be even better! So welcome to the project to the four accepted students, let's make it awesome.

We've been accepted as a GSOC 2010 organisation! - 18 Mar 2010

Moving from newsgroup to google group - 17 Feb 2009

The old newsgroup was getting too much spam, unfortunately, so we moved to a new Google group:
Please go there and sign in. You don't have to be signed in to read the group but you do have to be signed in to post, in order to stop spammers.

New students, and happy new year! - 01 Jan 2009

Four new students have joined the project as follows:

      - Maurits Dijkstra is working on porting MINIX 3 to the ARM
      - Anton Kuijsten is looking at tools to locate bugs
      - Michael Krekola is working on real time
      - Pambo Paschalides is working on improving documentation

We get € 2.5 million grant - 01 Nov 2008

Andy Tanenbaum has received an Advanced Grant of 2.5 million euro from the European Research Council to work on a project entitled "Research on Really Reliable and Secure Systems Software." The grant means that work on further developing MINIX 3 will continue to have funding for at least five more years starting today. That is VERY good news. This means our programmers can continue working on MINIX3 and several Ph.D. students and postdocs can be funded to push the research forward. Nevertheless, contributions from users such as drivers, ports, updating and translating the Wiki, etc.are very, very welcome. We'd like to build a bigger community.

Currently there are four Ph.D. students doing research relating to MINIX 3:

      - Raja Appuswamy is looking at advanced file systems
      - Cristiano Giuffrida is looking at live updates
      - Jorrit Herder is working on replacing failed components on the fly
      - David van Moolenbroek is working on execution environments

Another Ph.D. student is scheduled to start March 1, but we are looking for a postdoc. If you are interested, please see this ad.

New programmer joins us - 01 Aug 2008

A new programmer, Arun Thomas, has joined the project. He is working on porting the current version of X to MINIX 3 so we will support modern video cards.

Spam alert - 08 Jul 2008

The newsgroup, comp.os.minix, is full of spam at the moment. As practically all spam originates from google groups at the moment, it is recommended that as a solution for the short term, people don't post from google groups, and readers filter posts from google groups out.

New Ports

The following interesting new ports have been added recently.

Snapshots - 17 Apr 2007


As of today we're building weekly snapshots of MINIX. See This interface will probably get a bit fancier.

MINIX 3.1.3 prerelease - 13 Apr 2007

MINIX 3.1.3 Prerelease

An early preview of the next version has been released under version number 3.1.3, an interim release intended for developers who want to see the bleeding edge of MINIX and perhaps then track the current source. For more information, see the 3.1.3 release notes and the download page.

New ports - 06 Mar 2007

New ports: Links, an advanced text-based www browser, and also Links-2, a version of links that displays webpages in an X window. Some screenshots of it in action:


. Google

As yet, they're only compiled for the 'current' version of minix, and they aren't in the 3.1.2a packman list yet.

Exim available - 19 Feb 2007

New port: A message transfer agent, Exim.

Equinox desktop available - 10 Jan 2007

New port: Equinox Desktop Environment (and supporting libraries).

Minix screenshot of Equinox

Image Magick available - 08 Jan 2007

New port: ImageMagick (and supporting libraries).

New publications - 27 Dec 2006

A number of new publications about MINIX 3 have been added to the DOCUMENTATION page

Apache, subversion announcements - 03 Nov 2006

  • Apache has been ported. You can see it on the software page, and retrieve it using packman.
  • The tracking 'current' page has been updated for subversion.
  • The 'current' version of minix (in the subversion repository) contains a preliminary version of the VFS code, and the system profiling code.

VMplayer image available - 27 Oct 2006

A ready-to-run Minix 3.1.2a for VMware Player is available from the VMware page.

PowerPC port - 25 Oct 2006

Ingmar Alting has ported MINIX 3 to the PowerPC Platform. His Masters thesis is now available on the DOCUMENTATION page. We are integrating it into the main system.

We've switched to subversion - 06 Oct 2006

We've switched from CVS to Subversion for the MINIX source and ports repositories. There are fully fledged ports for the Subversion client and server for MINIX. The MINIX source project page can be found here: from where you can currently only browse the imported CVS repository.

This means that currently, the tracking 'current' page is out of date - it will be updated for an SVN version soon. Also the tools/ script will be updated. Also, the CVS mirror to the derelict MINIX machine is obsolete. We may find another use for the derelict, but currently it's obsolete itself as well. Of course we'd like to keep a MINIX3 machine in production, we just need a new job for it..

Those of you that are subscribed to the minix-updates-l on which CVS commits are posted, will be moved to the SVN commits mailing list.

The main reason for this change is that to incorporate recent improvements to MINIX (specifically, VFS and the PPC port), some MINIX source hierarchy will have to be changed, which is a dreadful job under CVS and loses historical state. With SVN, we will maintain proper history.

Article about MINIX 3 - 25 Aug 2006

There is an article about MINIX 3 on today.

VFS - 23 Aug 2006

Balasz Gerofi's masters thesis on a VFS for MINIX 3 is available now . When we have integrated the code, it will become a permanent part of the system.

Performance measuring tools - 20 Aug 2006

After the long summer break, more should be happening on the MINIX 3 front soon. One upcoming development is a very nice set of performance measuring tools. A Masters thesis describing the tools is now available now . The software itself will be available soon.

FLTK - 23 Jul 2006

We now have FLTK, the Fast Light Tool Kit, a nice little graphics package. You can get it using: easypack fltk-1.1.7

X11R6 available - 18 Jul 2006

A new version of X11R6 has been posted, which includes the gcc versions of the X libraries. They are installed in the /usr/X11R6-gcc/ root, i.e., in /usr/X11R6-gcc/lib.

Version management - 14 Jul 2006

  • There is a guide for updating your MINIX system to 'current' with CVS (a 'source upgrade'): tracking 'current'.
  • A recent change to packman makes it aware of Minix versions, which is important for backwards compatability if something in the Minix ABI changes. (This only happens as a last resort though.) The new structure knows about Minix versions, architectures, and beta and nonbeta ports. The structure is backwards-compatible with the latest official release (3.1.2a).

    To take advantage of this feature before the next release, you can do a source upgrade and obtain packages that have been recompiled to solve some problems due to ABI changes.

  • Recent new port highlights are ghostscript, ghostview, and libXaw3d. They're on the software page under the beta section, and available from packman and easypack.
  • The source snapshot has disappeared in favour of using CVS.

g++ available - 29 May 2006

The first public version of the g++ port is ready and available through packman (network package). g++ does require fixes that went into MINIX 3.1.2a. It is available now on the download page.

xv available - 07 May 2006

The first graphical program for MINIX 3, xv, is now available on the SOFTWARE page. This program can be used to view photos and other JPEG and similar files. This milestone (which depends on X), marks the start of transition from text-only to a more graphical user experience.

MINIX 3 on Xen - 28 Apr 2006

Ivan Kelly has ported MINIX 3 to Xen. His report and the code are listed on the DOCUMENTATION page or here.

MINIX 3.1.2 available - 18 Apr 2006

We have had 52,000 downloads - 13 Nov 2005

We have now passed 50,000 downloads of the MINIX 3 CD-ROM image file. As of today, it has been downloaded over 52,000 times.

gcc binaries released - 03 Nov 2005

The gcc package didn't contain the binaries, so it was not so useful if you didn't already have the gcc binaries. We made a gcc binary package on the SOFTWARE page under Beta packages near the bottom. Use easypack to get it.

Also, some small bugs in the ackpack packages were fixed today so if you are going to test it, please get the new one.

easypack bug fixed - 02 Nov 2005

There is a bug in easypack. A new one is on the SOFTWARE page. To install it under MINIX 3, log in as bin and type:

urlget >/usr/bin/easypack

Check the mode to see if it is executable.

Four beta test packages are now available. After you have installed bunzip2 and the new easypack, you can get them all by typing:

easypack dungeon-2.7.1 pdksh-5.2.14 unzip-5.52 zip-2.31

The ACK compiler in the distribution is an elderly one not generated from the ackpack sources. We we would like people to go to /usr/src/commands/ackpack and type ./build to rebuild the compiler, then test it heavily and report back to Thanks.

New email addresses - 30 Oct 2005

We have created several e-mail addresses for communicating with us:
  • (for reporting bugs)
  • (for sending us new software to test or reporting on existing beta software)
  • (for everything else)

90,000 visitors to the site so far - 27 Oct 2005

We have had about 90,000 visitors and almost 30,000 downloads so far. Hopefully a substantial number of people are now checking this news page and the newsgroup: comp.os.minix regularly.

Where to from here? We are working on a number of things at the VU, including automatic recovery from driver failures, a simple virtual memory model, and X Windows. But we are definitely interested in getting help from other people. Some things that would be very useful are:

  • Ports of more software
  • Device drivers
  • Another windowing system as a lightweight alternative to X
  • Ports of MINIX 3 to other architectures
  • Volunteers to test new releases
We may try to set up some infrastructure for community development, but for the moment, use comp.os.minix for suggestions and discussion.

Sitemeter installed - 26 Oct 2005

If you are interested in seeing how much traffic there is to the Website, there is a little colored square on the bottom of the main page you can click on. Note that this link was installed yesterday, after the flash crowd of over 50,000 visits had already passed. Also, on the DOCUMENTATION page, there is a link to a different traffic analysis near the bottom of the page.

By accident, bunzip2 was left off the CD-ROM. Without it, easypack does not work. Sorry about that. The binary is now on near the top of the page. Fetch it with urlget from The files bzip2 and bunzip2 are the same file, linked using both names. Sorry for the inconvenience.

Sucessful launch with 50,000 visitors yesterday - 25 Oct 2005

The launch yesterday was a great success. We have had over 50,000 visitors and over 12,000 downloads of the CD-ROM image in the past 24 hours. Due to popular demand, we have added a link on the main menu for the source code so you can inspect it using another operating system. It is also included on the CD image, of course.

We also added a sitemeter icon at the very bottom of the main page so you can observe the traffic.

Official release of MINIX 3 today - 24 Oct 2005

Today is the big day--The official release of MINIX 3. The SOSP CD and download file represent a major milestone, but the system is far from finished and your help is needed (see the HOME page). Some of the larger commands sources have been omitted from the compressed downloadable CD image to keep it from being 130 MB, but they are all available using the SOFTWARE link above.

This page will be used for communicating major news items about MINIX 3, but for day-to-day discussions, use comp.os.minix.

Here is some news about developments that are in the pipeline:

  • A first cut at virtual memory is now being tested
  • The port of X Windows is coming along well.
  • A port of the current version of python is in the works (python 1.5.2 is installed now)
  • The GNU POSIX tools are being tested now
  • The gcc compiler is available, but not well tested under MINIX 3. It lives in /usr/gnu/bin along with the rest of the GNU tools. To enable gcc and these tools, type:
         export PATH

Launching tomorrow - 23 Oct 2005

The CDs have been burned, the servers are provisioned and we are ready to go.

Last minute changes - 22 Oct 2005

Lots of last minute changes 2 days before the launch. It is a good thing we like living dangerously. All the reincarnation server related code has been updated, but not tested as thoroughly as we would have liked. Furthermore, perl and gcc have been installed.
