Haiku is a new open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

WHAT'S NEW IN HAIKU DEVELOPMENT

The Haiku source is continually built and released for testing purposes nearly every day. You can download and install these latest snapshots to check out the latest features and bug-fixes.

Be aware that nightly images may be unstable. Additionally, some packages included with official releases need to be installed separately.

If you're OK with this, you can find further instructions at our Nightly image page.

BFS Partition Resizer: Final Report

Blog post by ahenriksson on Wed, 2012-09-05 09:55

First of all, I apologize for the delay. I have now returned from my vacation, had a few days to settle in and explain to my neighbours that I'm not dead (!). Anyways, on to the interesting stuff.

On the surface, the status of things is mostly the same as in my last report, with a few bugs less. I thought I had dedicated more than enough time for bugfixing, but that turned out to not be the case. This is partly due to the slower development cycle when testing natively (compile, copy driver to image, boot virtual machine, test, repeat), and the bugs only showing up after doing several resizes with other IO going on. All the bugs of this kind that I know about have been eliminated.

To summarize the things I have accomplished during the summer:
  • Resize support in BFS driver, save for vnode mapping and growing a full file system.
  • Getting the resizing "pipeline" from userspace to driver to a working state (still needs some checking to verify that it's robust).

Google Summer of Code 2012: Wrap up report

Friday, August 24th marked the end of Google Summer of Code 2012. This was the sixth year that the Haiku project participated and was one of 180 fellow mentoring organizations. This year, five of 1,212 students were mentored by Haiku. To give a frame of reference to the competitiveness in Google Summer of Code, over 400 mentoring organizations and over 4,000 students applied to participate. For both mentoring organizations (and students), it is an honor and pleasure to be selected in Google Summer of Code.

For those not in the know, Google Summer of Code is "a global program that offers student developers stipends to write code for various open source software projects". In other words, simply by being one of the mentoring organizations, many youthful computer-savvy students may learn about HAIKU for the first time. For a carefully selected few, they have the opportunity to receive priority from our mentors in teaching them how to develop software for Haiku. This is a unique opportunity, as there is no other outreach effort of this magnitude available to the Haiku project.

x86_64 port: final report

Blog post by xyzzy on Tue, 2012-08-28 09:57

Since the three-quarter term report, I have continued porting userland servers and apps. The app server is fully functional, as are Deskbar and Tracker and a few other apps. I also cross-compiled all of the basic development optional packages (GCC/Binutils, autotools, make, etc.) for x86_64. Another screenshot showing the current state of things is below:

cpuidle: final report

Blog post by yongcong on Mon, 2012-08-27 12:18

the last quarter term is mostly spent on acpi cpuidle driver implementation. I also spent about 2 days to adjust the cpuidle framework so that the cpuidle generic module is loaded by lowlevel cpuidle driver, while the later will be loaded during boot up either by bus enumeration or calling get_module() manually. I also tested the power after acpi cpuidle driver is finished. The result is as good as intel native one. Since all the goals defined in my proposal are achieved, so the project is successfully finished.

Here I want to summarize the status:
generic cpuidle
generic cpuidle module is implemented which can be used on all cpu architectures;
x86 cpuidle driver
On x86 platform, we support intel native cpuidle driver and acpi cpuidle driver. The previous one make fully use of intel mwait extension support on intel newer cpus such snb, ivb or latter, since it won't touch the complex acpi part, it's preferred if the HW supports. The acpi driver is our last choice.
power saving number
On my T420 laptop, it saves about ~2.5watt
main limitation
we don't support old platform which doesn't have ARAT(always running apic timer). To support such platform, we need to enhance haiku's timer subsystem

I'd like to continue all the related power saving work in haiku such as to find and remove all the unnecessary wakeup source, to enchance haiku's timer subsystem mentioned above. I may also work on some acpi related driver, the acpi is complex but I learned a lot about acpi during this summer ;)

Finally I'd like to thank tqh for his guidance, carefully code review and kind help about ACPI related topics, thank haiku for giving me the chance to code for such a clean and beautiful operating system. I also owe a great deal to many haiku experts for their immediate answers on IRC or great suggestions on mail-list. The last thank belong to Google :D

OpenJDK port: final report

Blog post by hamish on Sun, 2012-08-26 23:43

Since my three-quarter term report I've been working on adding audio input support to the jsound port and fixing various bugs in the JDK. Since the AWT/Java2d and jsound ports are now completed, my goals for the summer have been accomplished! The OpenJDK port is now in a fairly usable state, and community members have been using it to run some large scale Swing apps such as NetBeans and ThinkFree office.

The next thing I would like to do is merge my work in to the Haiku port repository at the OpenJDK project. From there I'd like to look into the possibility of acquiring access to the Java TCK, which will allow for comprehensive testing of the port. This will no doubt uncover many bugs and keep me busy for a while. Here are some other possible areas of expansion for the future:

NFSv4 client: final report

Blog post by Paweł Dziepak on Sun, 2012-08-26 18:46

Since three quarter term I've added NFS-level support for named attributes what means that virtually all important NFS version 4 feature are now implemented, as I described them in my blog posts during the coding period. What still needs to be done is to improve support of Haiku's extended attributes and a lot of bugfixing. There is also a room for performance improvement and several possibilities to organize code in a better way.

Haiku Down Under 2012 Report

Blog post by Sikosis on Sun, 2012-08-26 06:41

If anything could go wrong -- it did go wrong at the Fifth Annual Haiku Down Under Conference for Users and Developers, held at The University of Queensland, Brisbane, Australia on 19th August, 2012. At least, that's how it initially played out.
