Der Morgen ist grau, das muss ein Dienstag sein! Meine Fediverse-Zusammenfassung des #DNIPBriefing heute #AusGründen etwas kürzer.
1️⃣ Ein simpel wirkendes Prompt hat in den letzten Wochen für einige Belustigungen in Teilen der DNIP-Redaktion gesorgt:

What if Dark Matter Doesn't Actually Exist?
A good chunk of cosmology is riding on whether dark matter exists or not. But what makes us so certain that dark matter is the answer—and what if we're wrong?

Abstract: Modern communication networks support local fast rerouting mechanisms to quickly react to link failures: nodes store a set of conditional rerouting rules which define how to forward an incoming packet in case of incident link failures. The rerouting decisions at any node $v$ must rely solely on local information available at $v$: the link from which a packet arrived at $v$, the target of the packet, and the incident link failures at $v$. Ideally, such rerouting mechanisms provide perfect resilience: any packet is routed from its source to its target as long as the two are connected in the underlying graph after the link failures. Already in their seminal paper at ACM PODC '12, Feigenbaum, Godfrey, Panda, Schapira, Shenker, and Singla showed that perfect resilience cannot always be achieved. While the design of local rerouting algorithms has received much attention since then, we still lack a detailed understanding of when perfect resilience is achievable.
This paper closes this gap and presents a complete characterization of when perfect resilience can be achieved. This characterization also allows us to design an $O(n)$-time algorithm to decide whether a given instance is perfectly resilient and an $O(nm)$-time algorithm to compute perfectly resilient rerouting rules whenever it is. Our algorithm is also attractive for the simple structure of the rerouting rules it uses, known as skipping in the literature: alternative links are chosen according to an ordered priority list (per in-port), where failed links are simply skipped. Intriguingly, our result also implies that in the context of perfect resilience, skipping rerouting rules are as powerful as more general rerouting rules. This partially answers a long-standing open question by Chiesa, Nikolaevskiy, Mitrovic, Gurtov, Madry, Schapira, and Shenker [IEEE/ACM Transactions on Networking, 2017] in the affirmative.

Simple Lösung für billigen Strom: "Die Solaranlage lohnt sich inzwischen immer - auch ohne Einspeisevergütung"
Der große Solar-Boom in deutschen Eigenheimen ist vorbei. Gut so, sagt das Solarhandwerk. Denn nach dem russischen Angriff auf die Ukraine wurde auf deutschen Dächern viel Schindluder getrieben. Die Technik lohnt dennoch, auch ohne Einspeisevergütung. Im Interview verrät das Solarhandwerk, warum.

U.S. lawmakers demand answers after Canadian man says border officers made him give DNA sample | CBC News
American lawmakers are demanding answers from the Trump administration after a Canadian man says U.S. customs officers held him for three hours and forced him to provide a DNA sample before sending him home.

The States That Will Not Be Commanded
There is a class of human experience that answers to no direct order. You cannot tell yourself to fall asleep. The instruction arrives at a locked door. Sleep refuses the simple transaction of command and execution. Instead, it assembles itself once certain conditions are present, and those conditions include, strangely enough, the act of picturing yourself already inside the state you are trying to enter.

Der Skandal ist nicht der Angriff, sondern ein System, das daran scheitert, ihn abzufangen. Signal ohne Regeln ersetzt keine staatliche Infrastruktur. Caspar Clemens Mierau hat in mancherlei Beziehung Recht, aber es ist schon bezeichnend, wenn jemand wie Klöckner u.a. auf einen simplen Phishing-Angriff reinfallen. Das zeigt etwas über deren Digitalkompetenz aus.

Abstract: Every 4 years, the PISA test is administered by the OECD to test the knowledge of teenage students worldwide and allow for comparisons of educational systems. However, having to avoid language differences and annotator bias makes the grading of student answers challenging. For these reasons, it would be interesting to compare methods of automatic student answer grading. To train some of these methods, which require machine learning, or to compute parameters or select hyperparameters for those that do not, a large amount of domain-specific data is needed. In this work, we explore a small number of methods for creating a large-scale training dataset using only a relatively small confidential dataset as a reference, leveraging a set of very simple derived text formats to preserve confidentiality. Using these methods, we successfully created three surrogate datasets that are, at the very least, superficially more similar to the reference dataset than purely the result of prompt-based generation. Early experiments suggest one of these approaches might also lead to improved model training.
