Today, July 31, marks another SysAdmin Day, a day on which we’d like to thank system administrators for their important work. From workstations to servers, networks, and applications, sysadmins ensure that everything runs smoothly every day and often solve problems before anyone even notices them. Our colleague Peter took a lighthearted look at the daily work of an IT admin. Was it satire and what is reality? Much of what he describes is actually closer to everyday work life than we’d sometimes like to admit.

Beeep… beep…
Crrr… sshhh… beep…
Squeeeek – wiiieeeuuuu – tick-tick-tick – beep!
What sounds like a telephone’s demonic possession is all too familiar to nostalgic souls and early tech adopters. This symphony of beeps and whistles didn’t herald the apocalypse, but rather the establishment of a connection between two modems. They were negotiating speed and protocols for data transfer.

Ten years ago, the Service & Communication department of the IT Center reached an important milestone: On May 23, 2016, the then IT-ServiceDesk received its initial certification under DIN EN ISO 9001:2015—and has been certified without interruption ever since. The department can thus look back on a decade of continuous quality management and successful development.

Regularly, so-called “time-related issues” arise in IT. These involve technical limitations in the processing of date and time data.

Bluetooth is an essential part of our modern everyday lives. Whether it’s wireless headphones in the office, a mouse and keyboard on a laptop, a smartwatch on your wrist or fast data exchange between two devices, the technology is always there to help us get ahead. Wireless technology helps to significantly improve the conditions for mobile working and learning. However, security gaps are a relevant issue both in everyday working life, where sensitive data is handled, and in everyday student life.
