Dear all,

POINTS. Everything that has reached me has been graded and all points have been entered into the system, but I kindly ask you to do the following before the exam:

1. Check for each homework that: (a) I have summed your T-points correctly to the circled points on the first page, and (b) I have entered the result correctly into Rapp.
2. Check for each homework that: (a) you have registered for Krypto15 in Kattis, and (b) that the points for your accepted submissions have been entered in Rapp. Note that if you did not register in Kattis before the deadline for Homework I, then it is quite likely that I have not entered all your results because I have not seen them.
3. Check that your presentation points are found in Rapp.
4. If something seems missing or not correct, then please summarize this on a piece of paper that you bring to the oral exam.

SPECIAL STUDENTS. If you are not in Rapp for this years course, then you are a "special student". I keep your results in a file. Feel free to email me and ask if you need to know your points.

PREPARING FOR THE ORAL EXAM. During the exam we first look at any potential note you bring about your points (see above). Then we consider your solutions, both theoretical and practical. You can point out grading errors or show that you understand something better than what follow from your solutions. If I have written "ORAL EXAM" or similar, then I expect you to do your best to fill in more details or clarify. I will ask about these things, but I may also ask questions randomly about the solutions to ensure that you understand them.

If you do not understand your solutions to the extent that I can be confident that you did them on your own, then you will fail the oral exam, but this has only happened a handful of times over the years, so if you did your work this is merely a formality.

More interestingly, I will give you more points or withdraw points for solutions of particular problems. I stress that this is not a theoretical possibility, the number points typically change for at least half the students and mostly in a positive way.

However, keep in mind that we only have 15 minutes per student on average so please think about what you want to say before you enter my room.

WHAT ABOUT HOMEWORK IV, WE DO NOT HAVE THE GRADED SOLUTIONS?  All students will not have the opportunity to ponder on their graded solutions for Homework IV. Fortunately, the only solutions that were somewhat confusing were those for Problem 6a) and 6d). Make sure that you can explain what you did if you solved these problems.

Good luck!

Doug

Dear all,

The graded solutions can be found at Studentexpeditionen.

The implementation points should now be in Kattis. Please let me know if you think you are missing any.

Doug

Dear all,

I have graded your solutions and reported them to Rapp. I will put your solutions at Studentexpeditionen Tomorrow for you to pick up and report the implementation problems to Rapp as well.

Unusually many solutions were hard to judge completely, in particular the problem with the distributed hash function. In some cases I have written "Oral exam!" or similar. This means that you should think through your solution and clarify during the oral exam to let me give you more points.

In some cases I have even given you zero points, e.g., an extreme case is if some of your argument are sound, but there is a fatal fundamental flaw that should reduce the points drastically unless I have misunderstood you. Thus, please pick up your solution and have a look.

I remind you that the sole purpose of the oral exam is to give all of you a fair grade. It allows me to check that you did your submitted work. It allows you to show a better understanding than what your solutions indicate as well as pointing out grading errors I may have made. There is no requirement that I have written "Bring up during oral exam!" to bring something up. In the past this has worked well.

There will be no questions about anything except your solutions.

Doug

Dear all,

I am truly sorry that I can not hand out Homework IV tonight.

Unexpected work that had to take precedence ate my afternoon.

Doug

Deal all,

Please note that the lecture Tomorrow is 10-12 in Room D32.

This is a guest lecture by Mats Näslund from Ericsson.

Doug

Dear all,

1. As explained earlier in class, lecture Tomorrow, May 22, is canceled.
2. As agreed in class, the guest lecture by Mats Näslund on Monday, May 25, is moved to 10-12. The room has not yet been decided and will be posted here tomorrow. Make sure that you go to this lecture and feel free to bring friends. There will be a problem on Homework 4 based on his lecture.
3. Homework 4 will be available on Monday, May 25, and the deadline adjusted accordingly to give you two weeks.

Doug

Dear all,

I have reported the results for the presentations as well as the T-points of Homework 2 into Rapp, except for a few people that are special in different ways. If you feel special, then you can send me an email and I will give you your results.

I-points of Homework 2 are easy to derive from your submissions, but they will also be reported as soon as the problems are put into the Homework 2 group of the Krypto15 course at Kattis. Until then it is difficult for me to see who solved what.

Doug

Dear all,

The rooms used for presentations are now listed under the "Booking" tab.

Please be there on time, since there are other bookings back-to-back with ours.
