Precipitation with 16 digits of precision, really? 

We are proud to have in Konstanz. According to Stiftung Warentest, an independent organisation for testing of goods and services for consumers, has the best weather forecast. „Best in terms of temperature and precipitation“ probably means how accurate the prediction is. If I want to go out, I want to know if it […]

Visit to Avira in Tettnang 

We do not have a lot of companies specialising in IT security in the Lake Constance area, so we went on a field trip to Tettnang on the other side of the lake to visit one of the larger companies, a bit more than an hour to drive. Around 30 students from the bachelor/master security […]

Mobile Malware 

We had two experts from Avira presenting on mobile malware this week.

Regional IT security challenges

Professors visit the students to ensure they are doing well and […]

Tower of Hanoi for information systems students 

I teach Introduction to Programming to students in our „WIN“ information systems bachelor study programme. When introducing the principle of recursion, it seems to be inevitable to talk about the Tower of Hanoi. A number of disks has to be moved from one of three rods to another. Because you can only move one disk […]

As an enhancement to my lecture Software Security we will prepare for and take part in two Capture the flag (CTF) competitions. Preparation will be supported by a student assistant. The first competition will be offense/defense style, the […]

Taught Introduction to Programming the first time, ca. 47% to 74% passed. Is that good? 

This semester, I taught Introduction to Programming for students in the WIN (information systems) study programme. I had 62 students signed up for the exam today, and only 29 of them passed. Should I be worried? Based on feedback from students who had taken the class in previous years, I had introduced some changes to […]
