oidc-agent - Integrating OpenID Connect Tokens with the Command Line
No full textThe oidc-agent is an OpenID Connect tool suite designed to simplify authentication processes for command-line applications and workflows that require access to resources protected by OpenID Connect. It provides a secure, but user-friendly way to manage tokens on the command-line, reducing the need for manual re-authentication. This paper presents an in-depth overview of the architecture and features of the tool suite, alongside its real-world applications. oidc-agent serves as a valuable tool in token based authentication workflows, particularly for applications in cloud computing, high-performance computing, and scientific research, where efficient and secure access to resources is critical
Chatbots verstehen und gestalten: Theorie und interaktive Praxis
No full textDer Online-Workshop „Chatbots verstehen und gestalten: Theorie und interaktive Praxis“ findet am 24.10.2025, 09:30 – 12:00, statt.
Am KIT wurden mit Workshops fast 60 Chatbots in Lehre, Forschung und Administration erstellt. In diesem Workshop werden die Erkenntnisse daraus vorgestellt. Nach einem theoretischen Überblick zu Funktionsweise, Anwendungsfeldern und Besonderheiten von Chatbots, geht es in die interaktive Phase.
Hier erhalten Arbeitsgruppen die Möglichkeit, direkt mit zu experimentieren und den Einfluss von Systemprompt-Anpassungen live zu erleben. Gemeinsam erkunden wir, wie gezielte Änderungen an der Kommunikation mit dem Chatbot dessen Verhalten und Antworten verändern können.
Der Workshop richtet sich an alle, die verstehen möchten, wie Chatbots „denken“ und wie man diese dialoggestützt aktiv gestaltet – praxisnah, kollaborativ und hands-on

No full textThis paper presents an integration study for the re-
cent power electronic-based fast-frequency response technology,
"asynchronous grid connection" which operates as an aggregator
for behind-the-meter resources and distributed generators. Both
technical feasibility and techno-economic viability studies are
presented. The fast-frequency response characteristics, validated
against Power Hardware-in-the-Loop experiments, are integrated
into an IEEE 9-bus system in DigSilent PowerFactory for system-
level dynamic analysis. It demonstrates that droop-based control
enhancements to local distributed generators allow their aggre-
gation to provide grid-supporting functionalities and participate
in the ancillary service markets. To this end, a long-term simu-
lation embedding the system within the ancillary service market
framework of PJM has been performed. The fast-frequency
response regulation is subsequently used to calculate the potential
revenue and project the results on a 15-year investment horizon.
Finally, the techno-economic analysis provides recommendations
for enhancements to access the full potential of distributed
generators on a technical and regulatory level
Large-scale phylogenomics reveals convergent genome evolution across repeated transitions to endosymbiosis in Enterobacterales
No full textSymbiogenesis stands among the major transitions in the history of life on Earth. Over the past three decades, extensive research has focused on specific host-symbiont associations to investigate their genome evolution. However, the idiosyncratic sequence evolution of endosymbionts has made it challenging to establish a robust phylogenetic framework for identifying broad-scale evolutionary patterns. Here, we establish the first genome-scale phylogenomic resolution for the Enterobacterales order, encompassing both free-living and endosymbiont species, and provide an analysis of gene loss and acquisition dynamics at scale. By examining over 200 genomes, we show remarkable consistency in phenomena previously known from scattered observations: a spike in gene loss invariably accompanies the shift to endosymbiosis, followed by a slower but continuous rate of gene erosion; gene acquisition processes are reduced after the lifestyle shift. Furthermore, convergence in gene family loss across independent and distantly related symbiotic lineages is observed, with genes having conserved functions and evolving under strong constraints lost at lower rates. Our results unify scattered observations into a broad-scale view of the consequences of endosymbiont genome evolution and highlight the roles of gene essentiality and dispensability in shaping convergent evolutionary trajectories
