Your comments will help us to assess and improve our courses, not only for future generations, but for your further study in CS&E. We really look at the results and appreciate your feedback! Several changes to the course over the years were a direct result of student feedback. And, as always, we'll publish the uncensored results on the course web site.


Note: Please do not enter "no comment" or something similar into comment boxes. If you don't have anything to say, just leave the box empty.

Question type : Long-answer
Answer at the bottom page (4 comments)

3. Other factors not mentioned above?
1: Chance to learn real OS skillz in a world-class course
6. What were the best things about this course?
1: * Wrote an operating system! That worked! * Use of real hardware (with all the joy that comes with this) * hands-on appreciation for microkernels and other OS concepts
2: Fun of making own OS. Exam was pretty good.
3: It's a challenge
4: The assignment :D. Being taught current research instead of dated techniques from years ago.
5: The project and an introduction to real world applications and research
6: a new insight on OS design issues like security and reliability
7: opportunity to design and build an os
7. What were the worst things about this course?
1: * 12 weeks * documentation * library code * Kenge does a complete rebuild after midnight
2: Doing it by myself.
3: It's quite a challenge
4: Time. Having the assignment due in week 12 limited my being able to do any bonuses, especially with other assessments due in week 12. It would be awesome if you submitted a working solution on time and were able to submit diffs to complete some bonus tasks afterwards. Most of the time my partner and I stayed a week ahead on deadlines, until we decided to do ELF loading and process management at the same time, which made some difficult bugs harder to find.
5: limited consultation time for the project.
6: not enough emphasis on research paper critical reading and evaluation during the semester which turned out to be a main component of final exam at the end of semester while programming project keep making us busy and unaware about other aspect of the course.
10. What background knowledge do you think you were missing that would have helped you in this course? Is distinction in COMP3231/9201 a suitable preparation? Is it too harsh?
1: Distinction in Comp3231 is essential.
2: Distinction is suitable
3: It
4: distinction in 9201 does not seem to be necessary
5: pre-reqs were fine
13. Which material do you think will be most useful to you in the future?  (required)
1: * Local OS research ... ;) * Performance evaluation (+ crimes) * Microkernels in general
2: threads/events and VM
3: C skills
4: General understanding of how operating systems work and microkernel design.
5: In the immediate future, SMP/Locking. Otherwise everything.
6: The lecture on Mac OS audio was great, i think this course should contain more info on drivers and
7: microkernel
14. Which material, not currently in this course, would you liked to have seen covered?
1: I though the OS X audio lecture was the most interesting lecture simply because of content: it presented a complete case study of one of the best audio subsystems (perhaps) in any general OS. If you had more time (you didn't) and more researchers like Godfrey who were in the right place at the right time (probably not many) then more stuff like that would have been awesome.
2: The lecture on Mac OS audio was great, I think this course should contain more info on drivers for monolithic operating systems.
3: booting processes
15. Which of the current topics would you like to see scaled back or excluded?
1: Cant think of anything in particular, I guess thats a good sign.
2: Maybe SMP+Locking ... I didn't really learn anything useful in this lecture, we don't have to deal with it in this course, and I know enough locking from previous courses (Extended OS and Foundations of Concurrency).
3: locking have been covered well in the previous OS course
18. Any suggestions for improving lectures?
1: 3 hour lectures are shit. Also, NICTA seminar room is terrible. Get a real lecture theatre... or anywhere where the chair don't slide around and we have desks.
2: 3 hours of listening alone is difficult... perhaps reserve the last 30-60 mins for interactive discussions?
3: Add another option above 'illness/misadventure'.
4: Cake ... ? More comfortable chairs!
5: Comfy chairs, maybe it was just me but i didn't like those chairs.
22. Any suggestions for improving the project?
1: For milestone 0, having some choice methods pointed out would be nice. Mainly because there are multiple ways to do the milestone, some easier than others. I took the highroad, partner found it harder by using more low level functions. it would have been nice to have the caching lecture BEFORE we implemented page tables and.
2: Some more exciting drivers would be nice.
3: Some of the specifications were far too vague, and were assessed on criteria that were not revealed to the students. More consistency in this respect would have been nice.
4: The biggest problem with the project is the loading time. Perhaps it would be best to get ELF loading operational first, then expand the functionality of other components
5: although from practical point of view the project was a good programming experience, all theoretical principal of mandatory parts of the project were covered in 9201. Maybe it would be usefull if student have to leverage some properties of microkernel to implement a more reliable or secure OS.
23. Any other comments/suggestions that might help us to improve the course in the future?
1: It was not clear to my group partner or I that you have to write a 1 to hardware to reset it. This made the driver milestone harder than it actually was. I *guess* it makes sense now, but a more gentle introduction to hardware would have saved us a lot of time! Some more information on Kenge/build system would have helped us to properly configure this too.
2: Maybe you should make it an individual project?
3: Thanks!
4: auto marking scripts are helpful to resolve conceptual problems which may not have been apparent from the specification. It can also be used to make sure that the milestone is complete such that a back log of required amendments do not arise
