Basics at RWTH: Using the VPN

At RWTH Aachen University, the Virtual Private Network (VPN) provides an important and secure connection to the university network. This connection is secured by encryption protocols such as TLS. VPN ensures that all data traffic – either to the RWTH network or, depending on the configuration, also to the Internet – is routed via a so-called “tunnel”. This tunnel protects the data on its way between your end device and the VPN server, where it is then integrated into the RWTH network. In the “Full Tunnel”, for example, requests from your device for external services appear with an IP address of RWTH Aachen University. In this article, we explain how you can set up and use the RWTH VPN service.

Most of us use them several times a day: emojis. Whether in a chat message to friends, on social media, or even in an email, these little yellow faces have become an integral part of our everyday lives. They help us express joy, irony, surprise, or compassion—often faster than words can.
In previous blog posts, we have already looked at the history of emojis. But this time we want to know: Which emojis do we actually like best and which ones do we dislike? Is it the classic laughing face with tears 😂 that accompanies every other conversation? Or does the red heart ❤️ come out on top?

Digital technologies have become an integral part of science and industry – but data centers are among the biggest energy consumers in the IT sector. High-performance computers in particular are essential for complex calculations in research, but at the same time cause high electricity costs and CO2 emissions. To meet these challenges, RWTH Aachen University is focusing on innovative solutions for energy efficiency and sustainable resource utilisation.
Neural Networks – The Basis of Modern AI

Neural networks are models inspired by the functioning of the human brain. They consist of artificial neurons that process information and communicate with each other. These networks enable machines to learn from data and recognise patterns without any explicit programming for each task. Examples include virtual assistants such as Alexa and Siri, translation tools such as Google Translate and creative AI systems such as ChatGPT. In this article, we will look at how neural networks work, what advantages and disadvantages they have and how RWTH Aachen University uses them.
