We are delighted to welcome two new trainees to the University IT and Data Center again this year on August 1st.

The HRZ is thus opening its doors to two young people who are beginning their apprenticeship as IT specialists for system integration - a profession that is of great importance in today's digital world.

The first day began with a warm welcome from the head of the HRZ, Dr. Rainer Bockholt. In his speech, he emphasized the importance of IT professions and the central role that the HRZ plays within the university. "As of today, you are an important part of our team and we look forward to shaping the future of IT services at the University of Bonn together with you," says Dr. Bockholt.

The welcome was followed by a short round of introductions, during which the new trainees had the opportunity to get to know their future colleagues and trainers. These initial contacts are essential for developing a strong team spirit and creating the basis for successful collaboration.

The apprenticeship to become an IT specialist for system integration is varied and demanding. It covers both theoretical principles and practical applications. Trainees learn how to plan, install and maintain complex IT systems. They also acquire knowledge of network technology, server administration and IT security. There is a particular focus on practical work: at the HRZ, trainees are involved in real, current projects from day one and have the opportunity to develop their skills in a professional environment. They are supported by experienced specialists who act as mentors and offer valuable tips and support.

As digitalization progresses and IT infrastructures become ever more complex, the need for qualified specialists is also constantly increasing at the University of Bonn. The HRZ has already trained many successful IT specialists in the past, who are now working in various areas of the IT sector - be it in university IT, in industry or at IT service providers. The new trainees at the HRZ therefore have the best prerequisites for starting a successful professional career. With the support of the entire HRZ team and the wide range of learning and development opportunities, they can look forward to an exciting and promising time.

In our new social media series “50 things you should know about the HRZ”, we are now providing small and large insights into the world of the University IT and Data Center of the University of Bonn.

On the occasion of the 50th anniversary of the University IT and Data Center, which will be celebrated in November 2024, the articles in the new series highlight various topics related to the HRZ - past and present.

The University IT and Data Center of the University of Bonn warmly congratulates its employee Maike Hacker on the successfu promotion in the subject of meteorology. 

An academic milestone
Ms Maike Hacker has successfully defended her dissertation titled "Modelling Fog and Low Stratiform Cloud in the Namib Desert with COSMO-FOG" on Tuesday, 30 July 2024 and graduated with "magna cum laude". Her work plays a critical role in the comprehension of complex interdependencies between atmospheric processes and extreme weather phenomena. 

Commitment and professional expertise at the University IT and Data Center
For several years Ms Hacker has been a valuable colleague in the department of Identity Management at the University IT and Data Center. Her technical expertise and her commitment significantly support and improve the security- and identity-management-processes at the University of Bonn. Her ability to transfer complex scientific findings into applicable IT solutions make her an invaluable pillar in our HRZ team.

A model for interdisciplinary work
The connection of meteorology, geosciences, and IT impressively demonstrates that interdisciplinary work can lead to outstanding results. Ms Hackers success is an inspiring example for the synergies that can emerge from the collaboration of different scientific disciplines.

A glance at the future 
We are proud to have Ms Hacker among us and are looking forward to realising more important projects with her. Her graduation marks not only a highlight in her own academic career but is simultaneously an important moment for us at the University IT and Data Center. 

In addition to the weekly, open video consultation hours,  in which questions can be asked about the structure, design, macros, functionalities and templates, the Atlassian team at the University Computing Center also offers Confluence training courses for Confluence users.

The short training courses with small exercises are designed for newcomers to working with Confluence. Participants receive an overview of the core functions of Confluence so that they can start working with Confluence immediately after the training.

The next dates:

• Monday, 26.08.2024 from 10:00 am - 12:00 pm
• Monday, 23.09.2024 from 10:00 am - 12:00 pm

Duration of the training: 60-90 minutes

Technical implementation: Zoom and Confluence (the Zoom meeting room will be opened 10-15 minutes before the start of the training to clarify any technical questions).

You will receive the access data in the Atlassian Tools area in Confluence (only accessible in BONNET/VPN).

Prior registration is not required.

Interested members of the university should participate in this training with a computer/laptop from the university network (BONNET) or via VPN. Confluence is only accessible via BONNET or VPN.

Inspired by the recently founded "Think Tank KI" of the University of Bonn, colleagues at the HRZ—whose usual responsibilities are already related to AI—have connected in an internal focus group under the name HRZ AI-Lab for the first time.

It is the objective of the HRZ AI-Lab to combine the existing knowledge of the HRZ staff about AI and respective expertise in core areas of AI, in order to support and actively enrich the work and development of the Think Tank AI. 

The meetings and events within the context of the HRZ AI-Lab are meant to give every interested employee at the HRZ the opportunity to discuss the development and use of AI-machines and to gain first practical experiences. 

First hackathon on 20 June 2024

On 20 June 2024, the first internal "hackathon" on the topic of AI took place as part of the HRZ AI Lab.

Initial experiences with large language models (LLMs) were gained during the event. For this purpose, virtual machines were set up in advance and the challenges and hopes for a possible productive operation at the HRZ were recorded. During the hackathon, various tasks were tested, including the operation of own models, the possible management of models, the strengths and weaknesses of user interfaces and the use of own databases. In the second step, the connection of GPUs is planned, which not only accelerate computing power, but also make some AI applications such as computer vision possible in the first place.

Scientific basis of AI

In preparation for the hackathon in the context of the HRZ AI-Lab the scientific background of an AI was explored. Three key areas were identified:

• Machine Learning (ML): An aspect of AI that is concerned with the developments of algorithms and techniques to allow computers to learn from data and make predictions.
• Neuronal Networks: Models which are inspired by the structure and functionality of the human brain and can be used for the processing of complex data patterns.
• Data science: The use of statistical methods and algorithms to analyse and interpret large amounts of data and their processing and use for the methods of AI. 

On 4 July 2024 it was time: The University of Bonn's annual Bergfest attracted students in the second half of their studies into the University's Botanical Garden for a day under the premise of "Celebrating the Achieved and Empowering for the Oncoming". The University IT and Data Center (HRZ) was also present with its own booth and presented a special highlight: A digital HRZ quiz for students to test their knowledge about the University's central IT-services. 

Directly at the entrance of the advice fair inside the mediterannean house was the HRZ booth: the 3D printer in production, informative posters and the friendly faces of the HRZ-employees invited the visitors of the Bergfest to learn more about the various IT-services of the University. Here students could not only ask questions but were also informed and advised by experts about central services, tools and storage solutions for research data, and possibilities for CPU-intensive research projects.

The big HRZ-quiz: Test your knowledge and win useful gadgets 

This day's highlight at the HRZ stand was the big HRZ-quiz: under the slogan "How well do you know your IT-services?" students could participate in the quiz in small groups or as individuals on the HRZ-tablets. A broad spectrum was covered by the questions and participants were challenged to demonstrate their knowledge about the different offers and services of the HRZ. Of course all quiz participants could get prizes: from useful gadgets such as the HRZ-Bergfest-bookmark from the 3D-printer to the exclusive HRZ carrier bag - the students went home not only with new knowledge but also with useful souvenirs. 

With Recogito Studio, the University IT and Data Center (HRZ) provides all lecturers with a system for the collaborative editing and annotation of media. The annotation tool can be used to annotate and analyze texts as well as graphics, images, photos and PDFs. Recogito Studio can be integrated into all courses and can also be used for small group work. Recogito Studio can be accessed in BONNET/via VPN at the URL http://recogito.uni-bonn.de and is therefore an important part of the digital infrastructure for studying and teaching at the University of Bonn.

Are you interested in working with Recogito Studio?

In the introduction video (see below) you will get a first insight into the use of Recogito Studio:

The department "IT-concepts and recommendations" at the University IT and Data Center was informed that the sale of indefinite Adobe-Acrobat-BUY licences for Acrobat Pro 2020 and Acrobat Standard 2020 was discontinued within the frame of the CLP-programme from July, 15th 2024. 

We advise the administrators of the University of Bonn to create a small "stock" of Adobe Acrobat purchase licences now, in case of foreseeable need (cf. https://uni-bonn.asknet.de/cgi-bin/product/P10016608).

Please take notice that the support end for Acrobat 2020 will be reached in June 2025. 

Note: Nowadays most applications can either create PDF files on their own or via the help of a "PDF-printer". For any further features (deleting pages from PDF-files, comments, text fields or text markings) there are many other free programmes (e.g. Foxit Reader or PDF24 Creator). PDF-forms can usually be easily created via LibreOffice. Many of the programmes are available for several operation systems, in other cases there are fitting products. Features going even further, such as (real) digital signatures or text recognition from scanned documents (OCR) a commercial product is usually needed (e.g. PDF Studio from Quoppa or FlexiPDF from Softmaker). Most of these products are cheaper than the Adobe Acrobat. We prefer products without connection to Cloud-services.

The products mentioned above are to be seen as examples and are not to be seen as recommendations. Support via the HRZ cannot be ensured for these products.
