Aus aktuellem Anlass: Mit der Missachtung von Gerichtsurteilen kennt die CSU sich aus. Auch die grün-schwarze Landesregierung in #BadenWürttemberg hat sich beim Thema #Luftreinhaltung damals nicht mit Ruhm bekleckert. Es kam dann nur so ne Pandemie und die Sache ist ein bissche…

EU-Justiz zu Zwangshaft für Politiker: Markus Söder kommt um den Knast wohl herum
Ein EU-Generalanwalt hält Haft für unzulässig, wenn Amtsträger gerichtliche Diesel-Fahrverbote missachten. Aber er geht den Ministerpräsidenten scharf an.

A systematic search for AGN obscuration variability in the Chandra archive
The nature of the obscuring material in active galactic nuclei (AGN) can be studied by measuring changes in the line-of-sight column density, $N_{\rm H,los}$, over time. This can be accomplished by monitoring AGN over long periods of time and at all timescales. However, this can only be done for a few selected objects as it is resource intensive. Therefore, the best option currently is to focus on population statistics based on the available archival data. In this work, we estimate a lower limi…

47 Tuc in Rubin Data Preview 1: Exploring Early LSST Data and Science Potential
We present analyses of the early data from Rubin Observatory's Data Preview 1 (DP1) for the globular cluster 47 Tuc field. The DP1 dataset for 47 Tuc includes four nights of observations from the Rubin Commissioning Camera (LSSTComCam), covering multiple bands (ugriy). We address challenges of crowding near the cluster core and toward the SMC in DP1, and demonstrate improved star-galaxy separation by fitting fifth-degree polynomials to the stellar loci in color-color diagrams and applying multi…

ByeBye Ryanair, go pollute someone else's air 👋
(France increased taxes on plane tickets so "in response" #Ryanair cancelled several French destinations)
Le Monde – Ryanair diminue ses activités en France après l’annonce de la hausse de la fiscalité sur les billets d’avion

Taxes sur le transport aérien : en colère contre la hausse de la fiscalité sur les billets d’avion, Ryanair diminue ses activités en France
Mercredi 30 juillet, la compagnie irlandaise à bas coûts a annoncé réduire le nombre de destinations qu’elle dessert dans l’Hexagone, arguant que ses marges sont trop affaiblies par la hausse de la fiscalité.

Analyzing and Evaluating the Behavior of Git Diff and Merge
Despite being widely used, the algorithms that enable collaboration with Git are not well understood. The diff and merge algorithms are particularly interesting, as they could be applied in other contexts. In this thesis, I document the main functionalities of Git: how diffs are computed, how they are used to run merges, and how merges enable more complex operations. In the process, I show multiple unexpected behaviors in Git, including the following: The histogram diff algorithm has pathologic…

Statt Kathedralenbau braucht Europa einen digitalen Bazar, meint Markus Beckedahlä: Offen, vielfältig, lebendig. Zentralisierung ist keine Antwort auf Vielfalt. Leider wollen viele Konsumenten aus Bequemlichkeit aber das All-in-One-Kaufhaus, das Amazon der sozialen Medien. Dabei könnte der Bazar viel bunter und spannender sein, aber eben nicht bequem #Medienpolitik

RIOJA. JWST and ALMA unveil the inhomogeneous and complex ISM structure in a star-forming galaxy at $z=6.81$
We report the discovery of a complex, two-phase ionized gas structure in the star-forming galaxy COS-2987 at $z = 6.81$, revealed by the unprecedented synergy between JWST/NIRSpec IFS and ALMA observations. These observations detect key emission lines, including [OII]$λλ$ 3727, 3730, [OIII] 4364, [OIII] $λλ$ 4960, 5008, [OIII] 88 $μ$m, as well as H$α$ and H$β$. JWST spectroscopy alone indicates interstellar medium (ISM) properties that are typical for galaxies at $z\sim7$. These include …

Agile Management for Machine Learning: A Systematic Mapping Study
[Context] Machine learning (ML)-enabled systems are present in our society, driving significant digital transformations. The dynamic nature of ML development, characterized by experimental cycles and rapid changes in data, poses challenges to traditional project management. Agile methods, with their flexibility and incremental delivery, seem well-suited to address this dynamism. However, it is unclear how to effectively apply these methods in the context of ML-enabled systems, where challenges …

Domain Knowledge in Requirements Engineering: A Systematic Mapping Study
[Context] Domain knowledge is recognized as a key component for the success of Requirements Engineering (RE), as it provides the conceptual support needed to understand the system context, ensure alignment with stakeholder needs, and reduce ambiguity in requirements specification. Despite its relevance, the scientific literature still lacks a systematic consolidation of how domain knowledge can be effectively used and operationalized in RE. [Goal] This paper addresses this gap by offering a com…
