Possible End to End to End Encryption: Come Help - Bert Hubert's writings
tl;dr: The European Commission is honestly asking for experts to advise them on ways to institute “effective and lawful access to data for law enforcement”. If you are an expert, I urge you to apply to join this group. You have until September 1st. Do read on for more details! The never-ending battle where police and intelligence services demand more/total access to communications shows no sign of stopping, even in the face of mathematical and practical impossibilities.

Have been watching Your Friends and Neighbors on #AppleTVPlus . No masterpiece, and somehow fairly annoying, but still somehow I want to watch all of it. I often find myself fast-forwarding through boring bits, though.

Block Alpha-Circulant Preconditioners for All-at-Once Diffusion-Based Covariance Operators
Covariance matrices are central to data assimilation and inverse methods derived from statistical estimation theory. Previous work has considered the application of an all-at-once diffusion-based representation of a covariance matrix operator in order to exploit inherent parallellism in the underlying problem. In this paper, we provide practical methods to apply block $α$-circulant preconditioners to the all-at-once system for the case where the main diffusion operation matrix cannot be readil…

Russian state media reported that during the Trump-Putin call, Putin reiterated his determination to continue pursuing the Kremlin's goals in Ukraine -- despite mounting international calls for a ceasefire.
Zelensky called on Ukraine's allies, particularly the United States,
to apply massive and immediate pressure on Russia.
"We need to ensure that for every such attack on people and lives, they (Russia) feel the corresponding sanctions and other blows to thei…

'Deliberately massive and cynical' — Russian attack on Ukraine began as Trump and Putin spoke, Zelensky says
"Patriots and their missiles are real defenders of life," President Volodymyr Zelensky said. "It is very important to maintain the support of partners in ballistic missile defense."

Classification of Extremal Dependence in Financial Markets via Bootstrap Inference
Accurately identifying the extremal dependence structure in multivariate heavy-tailed data is a fundamental yet challenging task, particularly in financial applications. Following a recently proposed bootstrap-based testing procedure, we apply the methodology to absolute log returns of U.S. S&P 500 and Chinese A-share stocks over a time period well before the U.S. election in 2024. The procedure reveals more isolated clustering of dependent assets in the U.S. economy compared with China which e…

Beware! The AI Act Can Also Apply to Your AI Research Practices
The EU has become one of the vanguards in regulating the digital age. A particularly important regulation in the Artificial Intelligence (AI) domain is the EU AI Act, which entered into force in 2024. The AI Act specifies -- due to a risk-based approach -- various obligations for providers of AI systems. These obligations, for example, include a cascade of documentation and compliance measures, which represent a potential obstacle to science. But do these obligations also apply to AI researcher…

Neues Kompakt-MacBook: Das konnte das alte, das erwarten wir vom neuen
Von 2015 bis 2019 hatte Apple mit dem 12-Zoll-MacBook ein praktisches Klein-Notebook am Start. Der soll nun wiederbelebt werden. Was das technisch heißt.

Sub-Scalp EEG for Sensorimotor Brain-Computer Interface
Objective: To establish sub-scalp electroencephalography (EEG) as a viable option for brain-computer interface (BCI) applications, particularly for chronic use, by demonstrating its effectiveness in recording and classifying sensorimotor neural activity. Approach: Two experiments were conducted in this study. The first aim was to demonstrate the high spatial resolution of sub-scalp EEG through analysis of somatosensory evoked potentials in sheep models. The second focused on the practical appli…

A May 22 move by the Supreme Court may signal the end of the NLRB’s independence, say labor leaders,
and transform the agency into an extension of the White House.
In turn, they warn, Donald Trump could use the board to reward friends and punish enemies. 
“It’s time to ring the alarm bell across the labor movement,”
said Jody Calemine, the director of advocacy at the AFL-CIO, the national union federation representing nearly 15 million workers across the country. 

‘It’s Time to Ring the Alarm Bell’
Labor leaders say a May Supreme Court decision could turn the agency that protects workers into a rubber stamp for President Trump.
