0.1.0 Work In Progress

It's been quite a while since we posted anything here, time to do something about that :-) Here is the good news: we are working very hard on the next FreeNOS release, version 0.1.0! We have decided to re-write the entire system from scratch, in C instead of C++. This is because we think that C++ is a beautifull language, but too unnecessary complex for our system. Althought it was a good experience to have tried this in a microkernel OS.

Together with the total rewrite of the kernel and parts of the userland, we are going to introduce the following interesting new things in FreeNOS:

  • Multi-Arch support: x86, MIPS and ARM
  • SMP support
  • Kernel threads support
  • Fault-Tolerance, a-la-MINIX 3.
  • Address Space Layout Randomization
  • Fully configurable builds (i.e. x86/pc with VGA console or x86/embedded with serial console)

Ofcourse, our system will be able to compile on all major OS's, including Ubuntu, Debian, Fedora, Gentoo, FreeBSD, OpenBSD and NetBSD. If you are interested, take a look at the current development code on SVN in the 'scratch' branch:

Cheers,

Busy, Busy, Busy

It's been some time since we posted something here, and not without reason. We are simply extremely B-U-S-Y =) That's not a bad thing per definition, but it leaves little time for FreeNOS so far. Nevertheless, we do our best to continue our work on 0.0.5. Most likely, this release will not contain many new features, only improve what is already in FreeNOS. This also means we're gonna try to make the system reliable, like Minix3!

Take care,

Niek

FreeNOS Interview at HAR(.FM) 2009!

The day has finally arrived: HAR 2009! We all got here yesterday, and are having a really great time. There are a LOT of interesting talks organized, cool workshops (especially lockpicking ;) and they even have their own radio station: HAR.FM.

Today, I met Luc Nieland of HAR.FM and he invited me for a live interview about FreeNOS! It was my first interview ever, but I really enjoyed it :-) Click har-fm-interview.ogg to download the interview.

Announcement: New Bug Tracking System!

The last few days we've been looking at the issue list of Google Code and we decided that as of today we'd use the list of issues in favor of flyspray. Google Code's Issue list provides us with extended functionality Firefly doesn't provide, like for example integration with the version control where we can close issues from svn commit messages. The issue history has been moved to Google Code and we're ready to start using our new bug tracking system!

You can find more information about Google's IssueTracker at http://code.google.com/p/support/wiki/IssueTracker.

Happy Summer Vacation!

The sun shines outside: summer is coming! Most of us are packing to leave for a well-deserved vacation somewhere on an unknown island not be mentioned here ;-) Anyway, work has already started on the next release, and maybe we'll have our 0.0.4 ready end of this month. I wish everyone a happy vacation, and meanwhile enjoy our news entry on OSNews.com !

0.0.3 Released

This version includes a new filesystem written from scratch: LinnFS. It is roughly based on the Extended FileSystem. It is now used as the root filesystem on the LiveCD instead of Ext2. Additionally, the notion of current directory has been implemented. Finally, this release has also been tested on the latest Nexenta distribution.
