- Didn"t take the course but received the evaluation anyway.» (?)
- Only went to the first lecture. The pace was way to slow for me so I felt that I"d do better sticking to the slides. Sorry about that, it"s nothing personal - had too many courses this period.» (0%)
- It probably was between 0% and 25%. The lectures were really boring, so the added value in going to the lectures compared to just reading the material seemed minimal, therefore I stopped going after a few lectures. The problem was the presentation style, not the content. » (0%)
- The Lectures didnt offer anything more then I could get from the book and the web based material. » (25%)
- With a lecturer that practically reads from the paper that is projected on the wall by the OH projector (which also is uploaded to the course website), I just see no reason to attend. It"s just impossible to keep focused» (25%)
- All my lectures collide with another course.» (25%)
- Did only go to about one lecture a week and none of the exercises. Did attend one lab time slot.» (25%)
- Knew most of the material before. » (25%)
- I would prefer to not have lectures to having this lecturer. He knows what is talking about, but knows nothing about didactics. The notes were good anyways.» (50%)
- the lectures they were really hard to follow basicly because of the teaching method which was boring» (50%)
- It became clear, after some time, that the lectures would not improve. During the lectures no proper explanations or proofs were made and it was therefore very difficult to understand the context of it all. The fact that all the "teachers notes" during the lectures were shown on an overhead severely complicated the ability to take notes, as the overhead-slides were shown at a much too rapid pace.» (50%)
- started to skip teaching as the teacher didnt teach anything but only tried to speak english while reading the overheads ster» (75%)

- Too much questions on details» (No, not at all)
- The examination contained several areas that the lectures had not covered. It was, in my mind, a complete misrepresentation of what the course should be about. According to the information given in preparation for the exam it was clearly stated that any calculator, chalmers-approved or not, was deemed ok to use. However, when the exam was to take place we were informed that only approved calculators were ok to use. This is, to be perfectly honest, unacceptable.» (No, not at all)
- I spent a lot of time learning: 1. The core functionality of modern operating systems. 2. Key concepts and algorithms in operating system implementations. 3. Implementation of simple OS components. But when I looked at the old exams I felt that they were testing my ability to learn old exams by heart more than anything else. I would have appreciated more open-ended questions that really gives the students the opportunity to show that they know 1,2,3 (above). The current questions are a little bit too narrow, but easy if you look at old exams.» (To some extent)
- More labs is probably better for learning more and getting a deeper understanding.» (To some extent)
- The focus was at a large degree on knowing things by hearth rather than understanding how it works.» (To some extent)
- The exam together with the labs did. The exam is more like a memory game. Which I think is ok, because labs were very interesting.» (To some extent)
- It was ok.» (To some extent)
- There were quite a few questions related to concurrent/parallell programming, especially on this terms exam. Although relevant to some extent, they should have been part of the required course parallell programming» (To some extent)
- I was not impressed with the exam. The question were a bit weird and there was no way when studying for the exam to know if you had it correct or not.» (To some extent)

- Did note read the course litterature only read the lectures. » (Small extent)
- wikipedia was good, and people working with the subject.» (Small extent)
- Didn"t have the book at all» (Small extent)
- Modern Reglerteknik by Bertil Thomas is in my opinion a better book.» (Some extent)
- It was better then the lectures, but that doesn"t say much...» (Some extent)
- The powerpoint slides were somewhat confusing, but the exams seemed to be based solely on them.» (Large extent)
- Good books, and the handsouts also» (Large extent)
- The course book was hard to get, though. In fact I ended up not buying it because of it, and instead used the Tanenbaum book, since I already owned that.» (Large extent)
- The book was one of the best Ive got so far. It not only included the important parts of the course but also included other areas of computer science and put it all together.» (Great extent)
- I found myself very prepared for the exam by just reading the OH paper used on the lecture. Lab 1 and lab2.2 was also of great help!» (Great extent)
- Good slides.» (Great extent)
- wikipedia and to some extent the course book provided information» (Great extent)
- The best book I ever read! Now, I read it every day even if the course has ended.» (Great extent)

- Didn"t take the course but received the evaluation anyway.» (?)
- The course homepage was very badly. All information was there, but the structure of the page was a mess so all information was tangled up in several diffirent fontstyles and pages so it was actually hard do understand. Especially the laboration pages was really bad. However, the lab-pm was good and clear.» (Very badly)
- The webpage could be organized a bit better. Its just to much information bombarding you from the screen and its easy to miss information if you are notcarefull because of that reason. This is especially for the laboration and exercise parts or the webpage» (Rather badly)
- Especially gathering information about the labs.» (Rather badly)
- Unstructured and hard to find what you are looking for. Especially the labs pages.» (Rather badly)
- For unknown reasons some of the handout material had to be bought at the local university store, rather than being integrated into the slides which were put online. That made the material a bit inconsistent (e.g. supporting diagrams where in the handout instead of in the slides).» (Rather badly)
- The course home page was very messy and hard to overlook.» (Rather badly)
- The only people that were of any use were the two persons responsible for the hand-ins and the excercises. The lecturer and the course responsible were of no use.» (Rather badly)
- lots of text on the website, hard to find links because they"re embedded in a lot of text it seems like it"s a good idea to have a separate website and not depend on the studentportal since that seems to crash when you need it the most...» (Rather well)
- I like that the lecture slides were available before the lectures where held. I do recall that some links on the labs were not updated for this year.» (Very well)

- Only time really was during the supervised labs, but you could be waiting for hours before it was your turn to get help. And once you got help, it was rarely that useful anyways.» (Very poor)
- lab assistants were unable to assist and examinator did not know what was oging on in the labrooms» (Very poor)
- Easy to get help at labs, not very friendly athmosphere for questions at lectures.» (Rather poor)
- The labassistents where very helpfull. They did a good job since they helped you enough to make it possible for yourself to solve the problem instead of serving a solution. I think that this approach made me work hard to try to learn as much as possible.» (Rather good)
- However, the lab assistants couldn"t help. They didn"t know the subject well enough. » (Rather good)
- The only people that were of any use were the two persons responsible for the hand-ins and the excercises. » (Rather good)

- Unfortunatly because of student related comnplications It was not possible to work togehter. » (Very poorly)
- My labpartner was a total idiot that was not nice to me. He tried to get me down or something by always say that I am wrong even when I was not. He never showed up when we hade decided for a meeting. He always rewrite my code (even if it was correct!). He has some serious issues to cooperate and will not be able to work in industry with that attitude.» (Very poorly)
- If we had not cooperated, we would not have had a chance of passing the course (with the way the hand-ins are set up). However, with an exam like this it is still very difficult, if not short of impossible, to pass the exam.» (Rather well)
- we had to cooperate between eachothers in order to complete the labs» (Very well)
- since you don"t get help from the teaching stuff it works well with your fellow students» (Very well)
- Me and my lab partner had a good cooperation.» (Very well)

- very low and then suddenly you had labs to hand in with short notice» (Adequate)
- Mostly because of the laboration load. The laborations could ease a bit with the load and they would be better.» (High)
- Labs were too hard, especially without any introduction.» (High)
- Shell lab took a lot of time... but it was worth it :)» (High)
- The idea of productive learning is not to compact 17 chapters and 3 lab assignments in 6 weeks.» (Too high)
- 2HP for lab assignments and the hand-ins is too little. The hand-ins took up 80% of all the study-time, which in turn affected the course that was read at the same time.» (Too high)

- lab deadlines collided» (Adequate)
- mainly because of the other course» (High)
- Had another course that took about 30+ hours each week.» (High)
- Too many chapters (lectures) were covered during the study period and also one too many lab"s were given. If the number of lectures reduces and we get more hands on experience that would make a huge difference in the way we learn things. We need to be prepared for the real world scenarios here, no need to focus so much on theory and on top of that we don"t even get graded for labs and spend sooooo much time on it. Some sort of load balancing would be great. If we are given all these labs to do why not get graded for it and have the lab contribute to your overall grade. It doesn"t make sense to be graded only on the exam but not the lab.» (Too high)
- Took too many courses... not your fault :)» (Too high)
- But not because of this course.» (Too high)

- Worst course I"ve had at Chalmers to this point. Lecturer seems distant and to lack knowledge about the course that he is giving. Labs were hard, especially since the lecturer weren"t able to prepare us be teaching us what we needed to know.» (Poor)
- replace or reeducate the teacher in todays operating systems aswell as the english language and preferrably some rethorics» (Poor)
- The worst course I have ever read. This is mostly because of the exam being as unfair as it actually was. The hand-ins were also way too big.» (Poor)
- In my eyes, a good course needs good lecturers that will keep the subject interesting and good at teaching. This course didn"t have that. He had terrible English and just wasn"t good at teaching. If the course was held in Swedish it probably would have been better, but now it was a real struggle for him to even get himself understood.» (Poor)
- I liked the content, but was really dissatisfied with the lectures. Also, small parts of the course seemed a bit old-fashioned and out-dated. In this day and age it seems a little silly to discuss magnetic storage (including tapes and floppys) but no flash drives. » (Fair)
- If the lectures improves, and the workload on the laboration could ease just a tiny bit i would give a higher grade.» (Good)
- Interesting topic!» (Good)
- Could have been better webpage.» (Good)

14. What should definitely be preserved to next year?

- The lab"s (lab TA"s have to be knowledgeable and not waste students time. I am sorry but I had two different classes same TA and I must say they are pretty useless.) I am sure other student"s feel the same way. I am curious to see other students input.»
- the book the courseplan the laborations and its crue»
- lab1, the excellent OH papers»
- lsh lab»
- the general direction of the material»
- Everything»
- Everything about processes and virtual memory, most about filesystem»
- The shell lab.»
- Lab2.1 and 2.2. The lecturer is good to explain and his tempo is very good. Do not change the course book!»
- The preassignments before the "real" labs.»
- The shell assignment. »
- slides.»
- The labs.»
- The assistants helping with the excercises and the hand-ins. They did theirs, and the examiners, job.»
- The focus on open operating systems, such that the implementations can be observed.»
- The labs. They were very good.»

15. What should definitely be changed to next year?

- Reduced number of lectures, power point presentation is a MUST. Organize the lectures a bit better so students can follow up easier and eventually show up for class. Way to many chapters were covered and simply there was not enough time to show up for lectures, do lab assignments and study for the exam at the same time. Class attendance was barely 25% this term and people struggle with exam preparation. »
- the lectures could have some more then just can be read from the book. For instance the lecturer could show concrete examples and show some real life examples about from the topics of the book»
- osp was a real pain in the ass, just understanding what to do took two thirds of the total lab time. I did learn a lot, at least of lab2.2, but it must be possible to make a lab with the same amount of learning without using osp. Especially, I think it was very unclear what I was supposed to do in the different procedures (so I spent a lot of time guessing what to do)...»
- teacher + the general setup of the course»
- More labs.»
- less parallelism and deadlock conditions, that"s a totally different course»
- Educate the assistants. Or at least give them a sheet with working code they can read from. Simple questions never got answered and took many hours to find. »
- Lab1. I think that it would be much more relevant to do another module in the OSP instead. The lecture slides with figures could be uploaded to the course web page.»
- Add solutions to past exams.»
- lecturer, »
- Do not use an old overhead projector when there is more modern alternatives. Do not make 75% of the slides from copyright protected copies which cannot be uploaded on the course homepage.»
- Godkänd på labrapport är under all kritik fick vänta alldeles för länge innan vi fick retur tom efter final deadline, lab1 lämnade vi in innan final deadline och fick inte retur förrän 6 veckor senare på dagen innan tentan med deadline 6 dagar senare. Den rättade vi till men tom nu vet vi inte ifall vi är godkända eller inte . Dåligt!!»
- Almost everything. It is embarrassing having an exam like that, especially with the incorrect information given beforehand.»
- The main lecturer was pretty uninspiring, as in, he knew the could course well and was very knowledgeable in the subject. However, the presentation was rather dull, with overheads being shown and read from slide to slide, no real interaction required from the students, and few things argued about on the blackboard.»
- He who gives the lectures...»

16. Additional comments

- Not to mention the fact that most students take 15 credit hours. I understand we are doing a Master"s program but focusing on theory as much as we do it"s pointless, we need to have hands on experience not theory. We need to be working on creative and innovative thinking which we can be acquired via lab assignments but theory wins and that is not helping us in anyways. We should be mastering skills that would put us in competition with other countries in the world. When we get out of school, nobody cares if we preach theory to the company we get hired for. Instead they want to see us make a difference. Now, how do we achieve that?»
- examinator could not speak proper english and he was constantly looking down at the floor trying to force the english (swenglish) words out of his mouth while reading the overheads line by line i could understand what he was talking about (most of the time) when i focused hard but i cant imagine students that are not from sweden understood much at all»
- Focus more on the operating system itself and not all parts around it. Like hard disks etc.»
- Make sure the lab assistants are aware of common problems and issues with the second labs since it seems like many groups had similar problems with that lab.»
- Even though the assignments were quite easy, I generally liked them. But I would have preferred to work with a real OS instead of OSP. I don"t like to learn APIs that have no practical relevance whatsoever. Maybe it would be nice to offer an alternative for the more seasoned programmers with a real OS, e.g. writing a kernel module for Linux, instead?»
- the teaching material is too much and adding the assignments we have to do,it is really hard. we spend so much time for the assignmets that is really difficult to find time for reading the theory»
- According to most of the people, if not all, that I have talked to about this course this course is one of the worst they have ever read. It was also way too difficult. Speaking to people reading the Automation and Mechanics program they really enjoyed their course. What is so different for them? As far as I have understood the difference is who the teacher is.»
- Didn"t take the course but received the evaluation anyway.»
- I thought the course focused a bit too much on the Unix part. From reading the course description, I thought it was more OS in general, but the big focus was on Unix systems (I would have enjoyed some more about Windows just to get two sides of the coin). Even though there probably are a lot of similarities, it would have been fun to see some differences and the reason why they chose it etc.»
