#Altersverifizierung im Netz betrifft nur Kinder?
Schon, aber wenn zum Kinderschutz das Alter überprüft werden muss, dann müssen natürlich alle demonstrieren, wie alt sie sind. Privatsphäre war gestern.
Und mit Google ist auch die #DigitaleSouveränität …

In meiner neuen Kolumne geht es um #Altersverifikation, #Kinderschutz im Netz, Smartphone- und Social-Media-Verbote und eine absurde App, die die EU gerade entwickeln lässt.

Hey NY, let Eric Adams know that he's a piece of shit.. er, wait, sorry, I meant let him know that making ebikes limited to 15mph (not the motor speed, but literally pedaling faster than 15mph) with *criminal* charges if you go faster is a terrible idea. Cars will still have a 25mph (or more) speed limit, only ebikes will be criminally charged for keeping up with car traffic on the road.

Monte Carlo Simulations of Polarized Radiative Transfer in Neutron Star Atmospheres
Soft X-ray emission from neutron stars affords powerful diagnostic tools for uncovering their surface and interior properties, as well as their geometric configurations. In the atmospheres of neutron stars, the presence of magnetic fields alters the photon-electron scattering cross sections, resulting in non-trivial angular dependence of intensity and polarization of the emergent signals. This paper presents recent developments of our Monte Carlo simulation, MAGTHOMSCATT, which tracks the compl…

Ukraine meldet elf Verletzte nach Angriff auf Charkiw
Bei einem schweren russischen Drohnenangriff auf die ostukrainische Stadt Charkiw sind laut Behörden mindestens elf Menschen verletzt worden. Unter den Verletzten seien ein fünf Monate alter Säugling und zwei Kinder im Alter von neun und zehn Jahren, teilten die Behörden mit. Die Drohne schlug demnach in der Nähe eines Wohnblocks ein, in dem Scheiben zu Bruch gingen.

NADI 2025: The First Multidialectal Arabic Speech Processing Shared Task
We present the findings of the sixth Nuanced Arabic Dialect Identification (NADI 2025) Shared Task, which focused on Arabic speech dialect processing across three subtasks: spoken dialect identification (Subtask 1), speech recognition (Subtask 2), and diacritic restoration for spoken dialects (Subtask 3). A total of 44 teams registered, and during the testing phase, 100 valid submissions were received from eight unique teams. The distribution was as follows: 34 submissions for Subtask 1 "five t…

STAR-RIS-aided RSMA for the URLLC multi-user MIMO Downlink
Rate splitting multiple access (RSMA) is intrinsically amalgamated with simultaneously transmitting and reflecting (STAR) reconfigurable intelligent surfaces (RIS) to enhance energy efficiency (EE) of the finite block length (FBL) multiple-input multiple-output (MIMO) downlink. An alternating optimization-based algorithm is proposed to jointly optimize the transmit beamforming matrices, STAR-RIS configurations, and rate-splitting parameters. STAR-RIS attains 360-degree full-plane coverage, whil…

Khronon-Tensor theory reproducing MOND and the cosmological model
We propose an alternative scalar-tensor theory based on the Khronon scalar field labeling a family of space-like three-dimensional hypersurfaces. This theory leads to modified Newtonian dynamics (MOND) at galactic scales for stationary systems, recovers GR plus a cosmological constant in the strong field regime, and is in agreement with the standard cosmological model and the observed cosmic microwave background anisotropies.

MeV cosmic-ray electrons modify the TeV pair-beam plasma instability
Relativistic pair beams created in the intergalactic medium (IGM) by TeV gamma rays from blazars are expected to produce a detectable GeV-scale electromagnetic cascade, but the cascade component is absent in the spectra of many hard-spectrum TeV-emitting blazars. One common explanation is that weak intergalactic magnetic fields deflect the electron-positron pairs away from our line of sight. An alternative possibility is that electrostatic beam-plasma instabilities drain the energy of these pai…
