{14} HelenOS and Google Summer of Code 2010

Google Summer of Code

Google Summer of Code is a program that offers student developers stipends to write code for various open source projects. Historically, the program has brought together over 3,400 students with over 200 open source projects, to create millions of lines of code. The program, which kicked off in 2005, is now in its sixth year…

HelenOS

HelenOS is a microkernel-based multiserver operating system designed from scratch. It decomposes key operating system functionality into many isolated but intensively communicating server processes that reside entirely in user space. HelenOS thus provides a computing environment that has several virtues, such as flexibility, increased robustness, well defined explicit interfaces and reduced complexity of individual components as compared to other operating systems.

HelenOS does not aim to be another clone of Unix or some other legacy system and is not POSIX-compliant (even though it may seem POSIX-similar at times). Instead, we try to design it according to our taste and sense for what is the most elegant and right thing to do. What makes HelenOS unique among the other multiserver operating systems is its multiplatform and multiprocessor microkernel. HelenOS will run on seven different processor architectures, ranging from a 32-bit uniprocessor little-endian ARMv4 to a 64-bit multicore big-endian UltraSPARC T1.

A Little Bit of History

HelenOS has traditionally been a project with significant student participation. Its first lines were written by a student in 2001. In 2004, the project turned into a collective academic effort and ever since then, new students have been joining every year to work on HelenOS-related theses and assignments. HelenOS and the Google Summer of Code are therefore a perfect match enabling more students from more universities to experience the thrill of the multiserver operating system development and also an opportunity for the project to get something back.

Students

We are looking for students with real interest in HelenOS. We are looking for people who will play nicely with our community and by our rules. We are looking for those who are willing to give their project the necessary time and care. If you only want to pass with the minimum effort, chances are that HelenOS is not for you. We are looking for already experienced C coders as all our projects start at the medium difficulty level and the code itself is by no means trivial.

If you are accepted, you will likely be asked to participate in the community mailing list and IRC channel from day one. We will also want you to periodically document your progress via mailing list write-ups and/or blog entries in a dedicated project blog. You will have a buddy (a.k.a mentor) in our team who will monitor your development and also provide you with guidance when necessary. Participating in our community will bring you the advantage of the possibility to discuss issues with more buddies than just your mentor.

Ideas List

The below Ideas List for the Google Summer of Code 2010 can be characterized as things that will greatly improve the usability of HelenOS while building on the core functionality already delivered by us in the past years and months. The individual projects are not excessively difficult and none of them poses a research topic in the academic sense. Instead, each item on the list is rather implementation-oriented, achievable in one trimester and something that we really need to be done. We especially did not plague the list with things that we do not need. In contrary, each idea on it is accompanied by a short explanation of why we think somebody should work it.

As you can see, the Ideas List is just a small subset of all open tickets for HelenOS. If you did not find an appealing topic on this list, you might want to consider looking at the broader list or suggest a completely new topic or a variation on an already existing topic. In both cases, talk to us so that we can see whether the new topic would work for HelenOS during the Google Summer of Code. If not, the idea may still seem interesting to us even outside of the Google Summer of Code program.

Google Summer of Code

Google Summer of Code is a global program that offers student developers stipends to write code for various open source software projects. We have worked with several open source, free software, and technology-related groups to identify and fund several projects over a three month period. Since its inception in 2005, the program has brought together over 4,500 students and more than more than 4,000 mentors & co-mentors from over 85 countries worldwide, all for the love of code…

We would like to invite prospective students to demonstrate their abilities and determination to work on a HelenOS project during the Google Summer of Code 2011 by completing a simple HelenOS task before the student application deadline on April 8. The task should involve building the latest mainline and either fixing a simple bug or contributing an improvement over the current HelenOS behavior.

A Little Bit of History

HelenOS has traditionally been a project with significant student participation. Its first lines were written by a student in 2001, now more than a decade ago. In 2004, the project turned into a collective academic effort and ever since then, new students have been joining every year to work on HelenOS-related theses and assignments. In 2011, HelenOS became a Google Summer of Code mentoring organization and successfully mentored three students during their journey through the program. HelenOS and the Google Summer of Code are therefore a perfect match enabling more students from more universities to experience the thrill of the multiserver operating system development and also an opportunity for the project to get something back.

Students

We are looking for students with real interest in HelenOS. We are looking for people who will play nicely with our community and by our rules. We are looking for those who are willing to give their project the necessary time and care. If a student only wants to pass with the minimum effort, chances are that HelenOS is not for him or her. We are looking for already experienced C coders as all our projects start at the medium difficulty level and the code itself is not trivial. Besides being an experienced C coder, a successful candidate should be a good communicator too.

If a student is accepted, they will be asked to participate in the community mailing list and IRC channel from day one. We will also want them to periodically document their progress via mailing list write-ups and/or blog entries in a dedicated project blog. They will have a buddy (a.k.a mentor) in our team who will monitor their development and also provide them with guidance when necessary. Participating in our community will bring them the advantage of the possibility to discuss issues with more buddies than just their mentor.

We would like to invite prospective students to demonstrate their abilities and determination to work on a HelenOS project during the Google Summer of Code 2012 by completing a simple HelenOS task before the student application deadline on April 6. The student should check out the latest mainline sources from our VCS repository, build the system, then either pick up an existing bug or enhancement or think of their own one, implement it, test it and submit the patch / public bzr branch / merge directive to us.

Interested students will need to fill out the following application form and attach it in their application.

Ideas List

The below Ideas List for the Google Summer of Code 2012 can be characterized as things that will greatly improve the usability of HelenOS while building on the core functionality already delivered by us in the past years and months. The individual projects are not excessively difficult and none of them poses a research topic in the academic sense. Instead, each item on the list is rather implementation-oriented, achievable in one trimester and something that we really need to be done. We especially did not plague the list with things that we do not need. In contrary, each idea on it is accompanied by a short explanation of why we think somebody should work it.

Last year we learned that some students may be under the false impression that the project ideas for HelenOS need to involve kernel programming. In general, this is a false assumption. Even though HelenOS is a microkernel-based system, most of the project ideas involve work on userspace parts of the system, such as libraries or server tasks. Having said that, we don't object kernel projects either.

As you can see, the Ideas List is just a small subset of all open tickets for HelenOS. If you did not find an appealing topic on this list, you might want to consider looking at the broader list or suggest a completely new topic or a variation on an already existing topic. In both cases, talk to us so that we can see whether the new topic would work for HelenOS during the Google Summer of Code. If not, the idea may still seem interesting to us even outside of the Google Summer of Code program.

Besides our regular project ideas, the HelenOS team will also sponsor ideas for selected related projects in the form of mentoring or co-mentoring.

{20} HelenOS and ESA Summer of Code in Space 2013

ESA Summer of Code in Space 2013 (SOCIS 2013) is a program run by the European Space Agency. It aims at offering student developers stipends to write code for various space-related open source software projects. Through SOCIS, accepted student applicants are paired with a mentor or mentors from the participating projects, thus gaining exposure to real-world software development scenarios. In turn, the participating projects are able to more easily identify and bring in new developers.

The project ideas for the Google Summer of Code can be characterized as things that will improve the usability of HelenOS while building on the functionality already present in the source tree. No project in the list poses an open-questions topic in the academic sense. Instead, each project is rather implementation-oriented and achievable in one trimester. Each idea is also accompanied by a motivation and a short explanation of why we think somebody should work on it. We expect the students to deliver code that could be seamlessly integrated with the mainline development branch of HelenOS.

In the past years we learned that some students may be under the false impression that the projects for HelenOS need to involve kernel programming. In general, this is a false assumption. Because HelenOS is a microkernel-based operating system, most of the projects involve work on the user space parts of the system, such as libraries and server tasks. Having said that, we don't object pure kernel projects either.

The Ideas List is just a small subset of all open tickets for HelenOS. If you do not see an appealing topic on this list, you might want to consider looking at the broader list or suggest a completely new topic or a variation on an existing topic. Remember that the ideas are not set in stone and, after all, it is the student who is going to suggest the idea to us. In any case, talk to us so that we can discuss whether the new topic would work for HelenOS during the Google Summer of Code. If not, the idea may still seem interesting to us even outside of the Google Summer of Code program. Besides our regular project ideas, the HelenOS team might also sponsor ideas for related projects in the form of mentoring or co-mentoring (see the list of cross-project ideas for inspiration).

For your convenience, before presenting the entire ideas list, we provide several views on the ideas grouped by a common theme. Click on the idea of your interest to see the detailed description.

{23} HelenOS and ESA Summer of Code in Space 2015

ESA Summer of Code in Space 2015 (SOCIS 2015) is a program run by the European Space Agency. It aims at offering student developers stipends to write code for various space-related open source software projects. Through SOCIS, accepted student applicants are paired with a mentor or mentors from the participating projects, thus gaining exposure to real-world software development scenarios. In turn, the participating projects are able to more easily identify and bring in new developers.

HelenOS

HelenOS is a portable microkernel-based multiserver operating system designed from scratch. It decomposes key operating system functionality into isolated but intensively communicating server tasks that reside entirely in user space. HelenOS thus provides a computing environment that has several virtues, such as flexibility, increased robustness, well defined explicit interfaces and reduced complexity of individual components as compared to other operating systems.

HelenOS does not aim to be another clone of Unix or some other legacy operating system and it is by design not POSIX-compliant (even though it may seem POSIX-similar at times). Instead, we try to design it according to our sense for what is the most elegant and right thing to do. What makes HelenOS unique among the other multiserver operating systems is its multiplatform and multiprocessor microkernel. HelenOS runs on eight different processor architectures, ranging from a 32-bit uniprocessor little-endian ARMv4 and commodity PC (x86 and x86-64) to a 64-bit multicore big-endian UltraSPARC T1.

A Bit of History

HelenOS has traditionally been a project with significant student participation. Its first lines were written by a student in 2001. In 2004, the project turned into a collective academic effort and ever since then, new students have been joining every year to work on HelenOS-related theses and assignments. HelenOS participated in ESA SOCIS 2013.

Who Are We Looking For?

We are looking for students with real interest in operating systems, system-level programming, software design and HelenOS. We are looking for people who will play nicely with our community and by our guidelines. We are looking for those who are willing to give their project the necessary time and care. If a student only wants to pass ESA Summer of Code in Space with the minimum effort, HelenOS is not a good match for him or her. We are looking for already experienced C coders because all our projects start at the medium difficulty level and the code itself is not trivial. The successful candidate should be a good communicator, too.

We would like to invite prospective students to demonstrate their abilities and determination to work on a HelenOS project during the ESA Summer of Code in Space 2015 by completing a simple HelenOS task before the extended student application deadline on May 7. The student should check out the latest mainline sources of HelenOS, build the system, then either pick an existing bug or enhancement or think of their own improvement, implement it, test it and submit the patch / public bzr branch / merge directive to our mailing list. Students interested in applying for a ESA Summer of Code in Space project also need to fill out the application form and attach it to their application.

If a student is accepted, he or she will be invited to participate in the community development mailing list and IRC channel from day one. We will also ask him or her to periodically document his or her progress via mailing list write-ups and/or blog entries. The mentor will act as a buddy in our team who will monitor the development and provide the student with guidance when necessary. However, as a first-class member of our development community the student will also receive feedback from other developers besides the designated mentor.

{24} HelenOS and Google Summer of Code 2016

Google Summer of Code is a global program focused on introducing students to open source software development. Students work on a 3 month programming project with an open source organization during their break from university. Since its inception in 2005, the program has brought together almost 11,000 student participants and 10,000 mentors from over 113 countries worldwide. Google Summer of Code has produced over 50 million lines of code for 515 open source organizations.

HelenOS

screenshot.png HelenOS is a portable microkernel-based multiserver operating system designed and implemented from scratch. It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. A failure or crash of one component does not directly harm others. HelenOS is therefore flexible, modular, extensible, fault tolerant and easy to understand.

HelenOS does not aim to be a clone of any existing operating system and trades compatibility with legacy APIs for cleaner design. Most of HelenOS components have been made to order specifically for HelenOS so that its essential parts can stay free of adaptation and glue layers, franken-components and the maintenance burden incurred by them.

HelenOS runs on eight different processor architectures and machines ranging from embedded ARM devices and single-board computers through multicore 32-bit and 64-bit desktop PCs to 64-bit Itanium and SPARC rack-mount servers.

A Bit of History

HelenOS has traditionally been a project with significant student participation. Its first lines were written by a student in 2001. In 2004, the project turned into a collective academic effort and ever since then, new students have been joining every year to work on HelenOS-related theses and assignments. In 2011, 2012 and 2014, HelenOS became a Google Summer of Code mentoring organization and mentored 10 students in total during their journey through the program. HelenOS and the Google Summer of Code make a perfect match enabling students from universities worldwide to experience the thrill of the microkernel multiserver operating system development.
