This year was an year of changes, the project didn't make an expected progress due to the changes in the development team, financial problems and some technical reasons.
However, Jari OS is still alive and development continuing. We slightly moving to the next stage - pure community-style development, however the strategy still the same - short range of features.
Special thanks for those who keep interest to the project.
I hope Jari OS will grow and new community members will join us, anyway thanks to all who made this platform works.
Thanks,
Lead of the Jari OS.
Due to technical difficulties and changes in the development team, Jari OS stable release is postponed for one year.
However, the project continues to evolve despite the current difficulties. The main directions of development at the moment are:
We will provide more documentation and specifications within next 2-3 month, most probably on December of 2010.
Anyway, we're looking for new development team and community members.
Sponsorship of the project was terminated, and at the moment the development of the project occurs independently.
Plans for the first stable release remain unchanged, but the directions of the project will be changed.
One of the first purposes are flexibility and scalability of the operating system, it must be able to create a platform for a variety of groups of developers.
The starting point is the ability to run Jari OS on SBC (such as Vortex86-based boards).
The project will pursue the following objectives:
The project has a few opened tasks, the list is here. There are a list of tasks/subprojects with highest priority:
In addition, the project will be carried out other research projects in the field of operating systems:
Research project has a lowest priority and will appears later.
Thanks.
Project moving to new repository, it will has improved build system, toolchain and other features to make development easy and friendly.
syslibs, core servers, applications and documentation repos will be splitted to one and new hiearchy will be created.
Thanks.
Milestone for a first stable version are fixed and will not be changed before release.
It's a small set of features, but it will makes a system generally usable for some use cases.
There are new milestone below:
And some sugar for a stable version:
In addition there are may be some small additions, in this case roadmap page will be updated.
More information on roadmap check out on this page.
One year ago, a small team of developers starts a new development stage. On september of 2008 we has only microkernel prototype, some ideas, and experience taken from the first stage. Those days was a team of three skilled engineers, and this team has a short deadline to design and implement OS prototype. Many things was changed from those days and new people came to team ...
For a one year we has a huge changelog, and many job done.
Our strategy is still the same: short range of features, really working components, short deadlines, no sugar ;)
Now we has a lack of documentation and build tools, but we will change this situation to a better one. Anyway we hope that we will provide a small and fully functional operating system within near 1 or 2 years. And, who knows, may be we will provide remote demonstration access to Jari OS host for everyone.
Thanks to all core team and community members - it was a great job!
Jari OS plans for a beta version has some changes.
First of all is a date: beta release moved to Q4 of 2010 - that means all subsystems features will be frozen and all works will be intended to bug fixing, code clean up and optimization. For near milestones there are will be a series of alpha releases (alpha1 and so on).
Second changes is a feature set, it was also chaned. We are planning to have the following list of features and changes in beta (and it's stable and optimized variant in stable version):
Also, we will try to add the following:
For the near time - for the alpha1 release we will show a progress with:
Alpha1 release is planned for september of 2009, other plans will be posted here in october of 2009.
Jari OS version 0.0.1 alpha is out.
All features are implemented, now we have an operating system platform for better development process.
It was a great job. Next releases will be more stable, more featured. We are planning to have a normal networking support, usb stack, ATAPI and other features for stable release (0.0.1).
Currently source tarball and raw hd image is available for download.
Jari OS now has a shared libraries support. This version is only initial support, we're working on better implementation.
Current implementation support only load time linking (i.e. dlopen() family function doesn't included yet).
To build applications dynamically follow the next instructions:
1. Make sure you have built Process Manager daemon from core services. Usually
you always build it, so this step is for consistency only.
2. Make sure you have built and install static syslibs. This requires 'make &&
make install' in syslibs directory.
3. From syslibs directory execute the following:
$> EXTRFL="-fPIC -DPIC" make install-shared
It will build and install shared syslib libraries to the same place, where
static libraries are.
4. In your initrd image create '/lib' directory and copy all .so libraries from
previous step.
5. In your jarios-application source directory exectute 'make clean && make &&
make install'. This will rebuild all applications against shared syslibs.
6. Build initrd image. Make sure it has .so libraries in its '/lib'.
Lambda Gears project (lgears) has joined to Jari OS, this project was founded by Stepan Zastupov to implement scheme compiler and virtual machine.
SchemeVM will be used as microkernel service to provide scheme applications and configuration interfaces running support. This will allow to create and provide secure interfaces to interact with operating system, also this means that in most cases we're can avoid huge amount of fork() and execve() calls.
We're planning to implement scheme library for interconnecting with other Jari microkernel services and API for writing modules for most of them.
You can checkout lambda gears via - git clone git://rep.jarios.org/lgears.git
Scheme applications might exchange C written utils and applications in future, and it can helps to provide clean and bug free environment for system.
