Haiku's application for Google Summer of Code 2009™ has been accepted!

This year, the role of Haiku's Google Summer of Code primary administrator has been taken up by Matt Madia, with Stephan Aßmus acting as the backup administrator. Over the past few days, Google program administrators evaluated a total of 395 Mentoring organization applications and published their list of those accepted on Wednesday, March 18th 19:00 UTC. As you may imagine, time had seemingly slowed to a crawl in anticipation of the results!

As usual, we have created a list of suggested ideas. We encourage interested students to begin considering possible projects and more importantly to engage yourself in our community!

Here's some anecdotal data involving Google Summer of Code from the past and this year. The number of mentoring organizations has grown from 40 in 2005, to 100, to 130, and up to 175 in 2008. There were roughly 500 mentoring applications in 2008, however a good portion of those were "spammy" and does not represent an accurate count of actual applications. Google's application process this year has greatly reduced the number of "spammy" applications. The number of participating students in 2005 was 400 and has grown over the years to 1125 as of last year. For this year, Google will be establishing a cap of around 1000 students for 2009.

Google Summer of Code 2008 and Haiku Code Drive harvest

News posted by axeld on Wed, 2008-10-08 09:18

We're very glad that Haiku has been part of Google's Summer of Code this year again. We were granted five student projects to improve Haiku. But since we had so many good and worthwhile project proposals, we set out to start our very own Haiku Code Drive. We asked for your help in the form of donations, and we were absolutely overwhelmed by the response we got from you, our community: we were able to sponsor 4 more student projects to work on Haiku.

Yes, of course, you know all of that already. The reason for this review is that, since both coding events are officially over by now, I wanted to give you an overview of what has happened, and how the students fared. Not all projects have been success stories, but we were lucky to have found some very talented students this year. We're glad we had you!

Google Summer of Code 2008

  • Andrej Spielmann has implemented sub-pixel antialiased rendering in the app_server. He was probably the only student that was always ahead of his schedule, and could even deliver more than originally anticipated. He also easily adapted to our coding style and produced a lot of quality code.
  • Dustin Howett intended to implement HPET support. At first, he struggled a bit with how to implement this in the best way, but eventually he found his way through this complex topic. However, he wasn't able to finish his project in time, and intends to keep working on it in the weeks to come.
  • Zhao Shuai implemented swap file support in the kernel that has recently been enabled. While it would be fair to say that the FreeBSD implementation and his mentor, Ingo Weinhold, helped him out a lot, he was very receptive of critics and always willing to try to understand how the kernel internals are working. In the beginning, he also wrote some overview documents about our virtual memory subsystem.
  • Alexandru Roman intended to add Zeroconf support to Haiku. However, he took a summer semester at school, and was surprised about the time commitment it asked for. He contacted his mentor, Ryan Leavengood, early on, and we're sad that he didn't manage to work on his project at all.
  • Adrien Lemaire was supposed to write a CIFS client for Haiku to let it access Windows shares. However, he was a bit overstrained with the project despite his nice application. He also didn't find the time to dig into the project, and unfortunately didn't deliver anything.

Haiku Code Drive 2008

  • Salvatore Benedetto intended to identify and fix most, if not all, of the remaining BFS bugs by first porting bonnie++ to Haiku. The plan was to add the missing functionality to Haiku that bonnie++ needs to run, in this case POSIX XSI semaphores. He experimented a lot with BFS, and we were able to fix several bugs together. He also implemented not only XSI semaphores, but also XSI message queues, and intends to complete his work by eventually adding support for XSI shared memory. During his project, he also ported the UDF file system to Haiku's current file system API. We're looking forward to see more from him :-)
  • Jovan Ivankovic was supposed to port CUPS, or parts of CUPS and integrate them with the Haiku printing layer. Unfortunately, he was not able to work much on it due to his health situation. We wish him the best!
  • Yin Qiu wanted to complete our ICMP handling in the networking stack. While he had a hard time with our coding style, he found his way through the stack, and came up with a good looking solution for error propagation and handling. Unfortunately it doesn't work yet okay, and is therefore not part of our repository yet, but he's continuing to work on his patch set. And we're patiently waiting for it :-)
  • JiSheng Zhang has written a DV media node based on the Firewire stack he ported as part of last year's Google Summer of Code. As far as I understand, he couldn't really test his work yet, though, as his Firewire hardware got lost at Olympia. In any case, he intends to stay with us to improve his work in the future.

So while we had our failures, overall we're very happy with our students. We hope to refine our selection process for next year, if we're lucky enough to be part of the Summer of Code in 2009.

And since our own Haiku Code Drive was so successful this year (even if we saved a bit of the money), we plan to continue this project in the future as well. On behalf of Haiku, let me thank you, the donors, again for making this possible.

I would also like to thank our mentors that have devoted much time for their students, and guided them through their projects.

Haiku Grows Swap Support

News posted by bonefish on Fri, 2008-08-29 15:34

Thanks to Google Summer of Code student Zhao Shuai successfully finishing his project Haiku does now feature support for swapping. As of revision 27233 it is enabled by default, using a swap file twice the size of the accessible RAM. The swap file size can be changed (or swap support disabled) via the VirtualMemory preferences.

Swap support finally allows building Haiku in Haiku on a box with less than about 800 MB RAM, as long as as the swap file is large enough. I tested this on a Core 2 Duo 2.2 GHz with 256 MB RAM (artificially limited) and a 1.5 GB swap file. Building a standard Haiku image with two jam jobs (jam -j2) took about 34 minutes. This isn't particularly fast, but Haiku is not well optimized yet.

Haiku's swap implementation was heavily inspired by that of FreeBSD. At the moment it is not as sophisticated, but Zhao intends to borrow more of FreeBSD's optimizations.

Haiku Code Drive 2008 to Sponsor Four Students

News posted by koki on Fri, 2008-05-30 20:00

It's official! Thanks to the incredible generosity of our community, and with a little help from Google, the Haiku Code Drive 2008 will sponsor four students, bringing the number of students that will be coding for Haiku this summer to nine. This is one more student than last year's eight sponsored by the GSoC alone! Shown below are the four selected students and their projects, in the order that the community ranked them through the Haiku Code Drive poll:

Salvatore Benedetto: BFS stress-testing, UDF port to new FS Haiku API

Jovan Ivankovic: CUPS port

Yin Qiu: ICMP error handling and propagation

JiSheng Zhang: DV media node

The response from the community to our call for donations to fund this program was incredible. In just two weeks, we received 120 donations from 24 countries (Australia, Austria, Belgium, Brazil, Canada, Czech Republic, Denmark, Finland, France, Germany, Hungary, Indonesia, Ireland, Italy, Lithuania, Netherlands, New Zealand, Poland, Russia, Slovakia, Sweden, Switzerland, the United Kingdom and USA), for a total of approximately $7,500. The promptness, degree of generosity, and global reach of the response by the community to the Haiku Code Drive is unprecedented in the history of our project, and hopefully a sign of things to come in the future.

The Haiku Code Drive 2008 offers each student $2,500 per completed project. So in order to fully sponsor four projects, on top of the community donations we are adding the $2,500 that we are scheduled to receive from Google for our participation in this year's GSoC. We consider this to be the best way to invest these funds, as they will both advance the goals of Haiku code-wise, as well as nurture the future generation of Haiku developers.

Finally, please join us in congratulating the selected students, and make sure you give them all the support and assistance that they may need. We want them to stay with the Haiku community for the long run. ;)

Haiku Gets Five Student Slots for GSoC 2008

News posted by stippi on Mon, 2008-04-21 20:42

After a quite intensive and challenging review and selection process, we are pleased to announce that Haiku has been assigned five (5) student slots for the Google Summer of Code 2008. This year, Google accepted many more mentor organizations than ever before, which made the allotment of students slots a lot more competitive. We also received applications of very high quality, which is definitely a blessing, but also made the Haiku mentor's task of narrowing down to a final selection much tougher. After thorough review of all the applications, and carefully taking into consideration factors such as immediate benefits for our project, the likelihood of getting long-term contributors, and the availability of an appropriate mentor for any given project, we have come up with the final list of students that will be coding for Haiku during the GSoC 2008 program. Here it is:

Paging (swap file) support

  • Student: Zhao Shuai
  • Mentor: Ingo Weinhold

Zeroconf support (automatic network service discovery)

  • Student: Alexandru Roman
  • Mentor: Ryan Leavengood

HPET and other timers (new ways for tracking system time)

  • Student: Dustin Howett
  • Mentor: Stefano Ceccherini

Sub-pixel antialiased rendering in the app_server

  • Student: Andrej Spielmann
  • Mentor: Stephan Aßmus

CIFS client (access to Windows shares)

  • Student: Adrien Lemaire
  • Mentor: Bruno G. Albuquerque

Please join us in giving a warm welcome to all the accepted students. Make them feel part of the Haiku community, as we want them to stay beyond the summer. And remember: their success is our success, so anything that we can do to assist the students complete their GSoC project successfully is for our benefit too.

We also want to thank all the other students that applied for a Haiku project but could not make it. We would have liked to accept them all, but that is sadly not possible. That being said, we are considering our own summer of code to sponsor one or more projects on our own, so please stick around. Better yet, if you are interested in this idea, contact us to discuss the details. To the community, stay tuned for more details, as you may have an opportunity to help make this happen.

Last but not least, a big thank you to the Haiku mentors who are committing their time to the success of this year's Google Summer of Code and, of course, to Google itself for making this happen and giving us the opportunity to participate again this year.

Haiku takes over Google, SoC renamed

News posted by mmu_man on Tue, 2008-04-01 13:17

With the help of a generous donator, Haiku, Inc. has acquired a major share of Google, Inc. and is now in the process of reorganizing Google for a major focus shift that will allow for wide distribution of Haiku R1 to OEMs. Distribution contracts have been signed with major mobile phone makers for an unprecedented availability of Phone and Handheld Integrated System Haiku (PHISH).

Also, as of this year, the Summer Of Code project is now officially renamed Summer of Assembler Poetry (SoAP).
