Data Networks

Dear Students,

It has been brought to our attention that the initial posted questions before the main part of Tuesday's lecture slides were hurtful to some people.

I would like to clarify that the intention was to highlight the important contributions made by women and other minorities in the field of computing.

Nevertheless, I do hear you, and will strife to introduce the lecture in a less controversial way in the future.

However, as for some of the comments posted by some students in the chat during that session:

As already noted during the lecture, those comments were and are absolutely unacceptable. You guys explicitly demonstrated that you lack the self reflection and necessary maturity to become engineers.

With best regards,

Tobias

Dear students,

we have an update regarding the MCQ test. Responding to some feedback we took the answer option "HTTP is a mostly stateless protocol" from the HTTP question out of the grading options. Then, we re-graded all exams and updated the scores in the CMS.

We wish you all the best with your ongoing studies.

We finished the correction of the Multiple Choice Test and published the results.
The test is only pass/fail (no grades, no bonus). As announced, passing the test is a requirement for writing the Midterm and, thus, for  writing the Final Exam.

A voluntary exam inspection will most likely be on Friday 02.05 after the lecture (16:00) in lecture hall 002 in E1.3. Please bring your student ID and an official ID document. During the Exam inspection you are not allowed to have any electronic devices with you or talk to each other. We will send a confirmation or update soon.

In case of capacity problems, assigned students have an advantage.

Hi all,

as mentioned, there is limited capacity for tutorials especially in person.
We assigned the tutorials based on preferences but not all preferences might be satisfied.

If you can't attend your assigned tutorial slot, please unregister from the tutorial to provide spots for others.
You can also try to find somebody to swap with.

Furthermore, we experienced that sometimes students do not show up to their assigned tutorials. Thus, if space is available you can join.

The slides from tutorials, explaining the solution for assignments, will also be shared via CMS.

Best regards,
The DN Team

Hi all,

we distributed all participants to tutorials based on the preferences. As mentioned, there is only a certain capacity for tutorial spots. Thus you might have been assigned to a Waiting List.
However, we will offer the Tutorial 1 (normally on Monday) as online tutorial in the first week since Monday is a holiday (Date TBA soon).
Everybody from the waiting list can either join this special online tutorial or the online tutorial on Wednesday in the first week (Zoom links TBA soon).
Therefore, everybody has the chance to attend the first tutorial before the MCQ.
After the MCQ, tutorials might be reassigned if capacity is available.

Best regards,
The DN team
