Dear students,

we would like to remind you that the deadline for creating or joining a team for the assignment submissions is tomorrow morning at 10am. If you are still looking for a team, you can use the forum. There are still open threads.

Please note, that only submissions in groups of 2 to 3 students are allowed. Individual submissions will not be graded.

Kind regards,

Dear students,

as already announced, we will make use of Jupyter notebooks throughout this lecture. To run these notebooks, we require a Python installation and a couple of Python packages. In addition, a few of the notebooks also require third-party software such as PostgreSQL or Neo4j. Therefore, we provide you with a virtual machine that already has everything installed.
Unfortunately, some of you encounter problems regarding the installation and/or use of the virtual machine, e.g. the installation does not work on MacBooks with M1 chips.

However, you do not necessarily need the virtual machine! For the assignment sheets, you will only need Python and the corresponding Python packages (no third-party software). Thus, if you are unable to use the virtual machine for whatever reason, you can also manually install the required software.
You can find instructions on how to manually install Python and the Python packages here. The link is also available under Information > Manual Installation.

Kind regards,
Your BDE Team

Dear students,

we have now assigned you to your tutorial groups. You can find your assigned tutorial on your personal status page. The tutorials will start next week. More information can be found in the Timetable.

If you were assigned to Tutorial 8 (Sunday, 00:00 NO Tutorial) but still want to attend a tutorial at some point, you are welcome to attend the online tutorial on Tuesdays 10:15 - 12:00 on our Discord server.

Notice!
Tutorial 2 (10:15-12:00,  E1.1 R 2.06) and Tutorial 4 (12:15-14:00, E1.1 R 2.06) next week Monday 24.04.2023 will be held in building E1.7 R 001. The usual seminar room 2.06 in building E1.1 is occupied on Monday.

Kind regards,
Your BDE Team

Dear students,

we have just uploaded Assignment 01. Instructions for the submission can be found at the end of the document.

Please note that the submission is only allowed in teams of 2 to 3 students. Furthermore, we ask that you try to form teams of exactly 3 students to reduce the number of submissions.

To register your team, you have to use the Team Groupings functionality of the CMS. This means for you that a team member creates a group in the CMS on the personal status page and invites all other team members to the group. You can create your team until Thursday 27.04.23 at 10:00am, after that it is not possible to change the team. If you need to change your team during the semester, please contact your tutor.

If you haven't found a team yet, you can use our forum to find one.

Kind regards,
Your BDE Team

Dear students,

we would like to remind you that you can change your preferences for the tutorials only until tonight.
Please note that we had to reset your initial preferences on Monday, 17.04.23, due to the addition of the online tutorial.

You can find a detailed overview of the available time slots in this previous news post.

Please submit your tutorial preferences on your personal status page by 23:59 today!

Kind regards,

Dear students,

due to significantly more registrations for our lecture this year, we decided to offer one additional online tutorial. This tutorial will be held on our Discord server every Tuesday at 10:15 - 12:00. You can find more information about our Discord server under Information > Discord.

We now have the following tutorial slots:
    •    Slot 1: Sunday, 00:00 NO Tutorial: This is a dummy tutorial! Please give preference to this tutorial if you do not plan to attend the tutorials in general and rule out the other tutorial choices.
    •    Slot 2: Monday, 10:15 On-site Tutorial: Two regular tutorials at this time slot in E1.1 R2.06 and E1.1 R3.06
    •    Slot 3: Monday, 12:15 On-site Tutorial: Two regular tutorials at this time slot in E1.1 R2.06 and E1.1 R3.06
    •    Slot 4: Tuesday, 10:15 Online Tutorial: Online tutorial on our Discord server.
    •    Slot 5: Tuesday, 12:15 On-site Tutorial: Two regular tutorials at this time slot in E1.1 R2.06 and E1.1 R3.06

Note, that by adding the online tutorial, we had to reset your initial preferences!

Therefore, we extended the deadline for the tutorial preferences by one day (20.04.2023, 23:59).

Kind regards,
Your BDE Team

Dear students,

in the course of this lecture, we will use Python and in particular Jupyter Notebooks to explain various concepts. For a few notebooks, we also require additional software (e.g. PostgreSQL). Therefore, we provide a Virtual Machine that has all the required software and systems already installed. You can find detailed instructions at the following Github repository. The link is also available under Information > Vagrant.

We spent a lot of time preparing the tools and the instructions. Please read them carefully before asking questions. You can also consult the threads under bde22 > Technisches in our forum and check previously asked questions. We also provide a small FAQ.

Please note, that you are also able to run most of the notebooks by just having a Python installation with the required packages.

If you still have problems with the installation, you can either ask a question in the forum (bde23 > Technical Problems) or visit our Office Hour on Wednesday, 19 April at 14:15.

Kind regards,
Your BDE Team

Dear students,

you can now choose your preferred tutorial slots on your personal status page. You can change your preferences until 19.04.23 at 23:59.

We offer six regular tutorials at the following times.
    •    2x Monday, 10:15 - 12:00
    •    2x Monday, 12:15 - 14:00
    •    2x Tuesday, 12:15 - 14:00

In the tutorials, we will in general briefly discuss the solution of the previous assignment sheet. However, the main focus will be a recap of the lecture material by providing additional exercises.
Please note, that both the solutions of the assignment sheets as well as the tutorial slides including solutions will be timely uploaded to our Materials.

Because of this, experience has shown that some students will not attend the tutorials in person. Therefore, we also created an additional (pseudo) tutorial (Slot 1: Sunday, 00:00). Please give preference to this tutorial if you do not plan to attend the tutorials in general and rule out the other tutorial choices. With this, we can allow students that plan to attend, to more likely get their preferred choice. Furthermore, we can better assess how many in-person tutorials we really need. Of course, you can always attend a tutorial if you change your mind.

Kind regards,
Your BDE Team
