{14} HelenOS and Google Summer of Code 2010 (9 matches)

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 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.


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.
