Dear all,

The results of the backup exam are now visible in the CMS. I will upload them to the LSF after the exam inspection.

The exam inspection will take place on April 05, 10:00–12:00, in CISPA (E9.1), room 0.07. To coordinate the inspection, please book a time slot via the link at "UdS Book Backup Exam Inspection Slot" in the course materials in CMS. 

Dear participants from UdS,

All UdS students registered in LSF/HISPOS have been assigned a seat for the backup exam on Friday, 22.03.2024, between 10:00–12:00 in the E3.1 HS002 lecture hall.

Please check the CMS for your assigned seat. If you can't register in LSF (e.g., Erasmus, non-CS department,...) but intend to attend the exam, please contact me ASAP to get a seat assigned.

Further, I added a 1h recap lecture to the "5 Old Exams" section of the course materials, where I explained again some lecture content that I noticed was frequently misunderstood in the endterm exam.

Dear all,

The exam results are now in the CMS under "UdS Exams" or "LUH Exam," respectively. I will enter the grades into LSF and QIS later today.

For the exam inspection:

UdS Students: Exam inspection will be on Wednesday, Mar 06, between 15:00–17:00 in room 0.07 at CISPA E9.1. Please note that we'll only allow four students at a time in the room.

LUH Students: Exam inspection will be online via BigBlueButton in Stud.Ip (a corresponding room should be visible there to you) on Friday, Mar 08, between 10:00–12:00. You need to book a slot for your inspection. A link for booking slots will be posted in the CMS Course Materials section today at 13:00. Please book by Thursday at the latest.

Dear participants from UdS,

All UdS students registered in LSF/HISPOS have been assigned a seat for the exam on Thursday, 22.02.2024 between 10:00–12:00 in the GHH in E2.2.

Please check the CMS for your assigned seat. If you can't register in LSF (e.g., Erasmus, non-CS department,...) but intend to attend the exam, please contact me ASAP to get a seat assigned.

Update:

Since there was no update from the LUH Dean's office, the exam will take place as planned tomorrow at 08:00 despite the ÜSTRA strike. I hope to see all that registered in QIS tomorrow at the exam!

Dear all,

Here is some information about the exam at LUH next Tuesday, Feb 20:

• The exam starts at 08:00, so please be there on time
• The exam sheet is in English, but you can answer in English, German, or a mixture thereof (as long as it remains legible)
• You can bring a Duden; however, I’ll be present during the exam to help out in case of language barriers or if an exam question is unclear
• No cheat sheet or notes
• Writing utensils must be permanent (i.e., no lead pencil) and not red or green colored.

If there are any other questions, please use the Askbot or contact me.

PS: Sorry for the potential double posting, but my direct email bounced for several students.

Please note that there was an error in the answer for Question 3.1 in the sample solutions for the old exams. The incorrect answer was an artifact from an old version of that question where the root CA was pinned for any connection. A revised version with additional explanations was uploaded to the CMS. Thanks to the students who spotted this!

There were complaints about the ads in the lecture videos. I understand that ads are annoying, but I am not placing them in the videos. I am not monetizing the lecture videos. Google shows the ads if you watch the videos with a non-premium account. If the ads are too annoying for many of you, we can consider another platform to publish the videos, though some features of YouTube, like streaming videos, chapters, etc, might be lost. If you think we should move the videos somewhere else, I would appreciate advice/wishes in an Askbot discussion.

The recording of the flipped classroom is online, and the slides and the quiz are in the Materials section. The link to the recording is in the schedule. Further, I added three short videos to the Crash Course playlist on Youtube, which show how to a) request and use dangerous permission, b) use signature permission with/without knownSigner to protect app components, and c) delegate access rights via PendingIntents.

Have a nice weekend!

The link for a recording of today's flipped classroom has been added to the lecture schedule. Unfortunately, the recording during live lecture crashed and this is only a re-recording of my part. Please add the questions that you remember being asked during the lecture to Askbot. I will answer them in Askbot, so we have at least a written collection of the Q&A of today's classroom.

Exercise 01 has been published in the course material section, both the PDF of the exercise sheet and the APKs for the practical parts.
