Tesla's German EV Registrations Plummet 41%, Ranking Falls

Tesla's new EV registrations in Germany plummeted 41% in 2024 to under 38,000, dropping to third place in market share. This decline is attributed to CEO Elon Musk's controversial statements and a lack of recent innovation, despite the Berlin Gigafactory's initial promise. Competitors like BMW and VW outperformed Tesla, highlighting challenges faced by the US automaker in the German market, including legal issues, environmental protests, and lower-than-expected sales at its Berlin plant.

EHT Reveals Turbulent Accretion Flow Around M87*'s Black Hole

2025-01-25

The Event Horizon Telescope (EHT) Collaboration has released a new analysis of the supermassive black hole at the center of Messier 87 (M87*), combining observations from 2017 and 2018. The study confirms that M87*'s black hole rotational axis points away from Earth and highlights the significant role of turbulence within the accretion disk in explaining the observed shift in the ring's brightness peak. Using a vastly expanded simulation image library, the team confirmed the counter-clockwise 30-degree shift of the brightest region of the ring between 2017 and 2018. This research represents a major step forward in understanding the complex dynamics of black hole environments.

From Nero's Poison to Turkish Jam: The Deadly Double Life of Cherry Laurel

2025-03-11

The author discovers a cherry laurel tree in their backyard, a plant whose fruits and leaves contain the deadly poison cyanide. Historically, it was used by Locusta, Nero's poisoner, to assassinate enemies. However, cherry laurel has also been used as a food flavoring; 19th-century British cooks used its leaves in puddings, resulting in child poisonings. Today, in Turkey, ripe cherry laurel fruits are made into jams and other foods. The article engagingly recounts the plant's transformation from ancient poison to modern food, warning against confusing cherry laurel with bay leaves to prevent accidental poisoning.

Differentiable Logic Cellular Automata: From Game of Life to Pattern Generation with Learned Recurrent Circuits

2025-03-07

This paper introduces DiffLogic CA, a novel neural cellular automata (NCA) architecture using a fully discrete cell state updated via a learned, recurrent binary circuit. Replacing neural network components with Deep Differentiable Logic Networks allows differentiable training of discrete logic gates. The success of applying differentiable logic gates to cellular automata is demonstrated by replicating Conway's Game of Life and generating patterns through learned discrete dynamics. This highlights the potential of integrating discrete logic within NCAs and proves differentiable logic gate networks can be effectively learned in recurrent architectures. While promising, training for complex shapes remains a challenge, suggesting future work on hierarchical architectures and specialized gates for improved state management.

Discord Ads: High CPMs, But Still Experimental

Discord Ads: High CPMs, But Still Experimental

Discord's ad products currently use a fixed pricing model based on projected reach, frequency, brand lift, and user engagement. Premium inventory CPMs range from roughly $25 to $30, varying by format, region, and reach. Discord uses CPM pricing instead of CPA because both views and engagement provide value, and it's the right economic model for them, competitively positioned within the premium tier but below the highest-priced platforms. While advertising holds promise, it remains a relatively experimental business unit for Discord in 2025; most revenue comes from its Discord Nitro subscription service.

X Platform Bans Signal.me Links: A Blow to Privacy?

X Platform Bans Signal.me Links: A Blow to Privacy?

Elon Musk's X platform (formerly Twitter) has recently banned links to Signal's "Signal.me" URL, preventing users from posting them in DMs, public posts, or even their profile bios. This move raises concerns, as Signal, with its end-to-end encryption and privacy focus, is a crucial communication tool for journalists and whistleblowers, particularly relevant amidst recent US government data leak controversies. While users can still share their Signal usernames manually, this added friction impacts communication and potentially threatens information security and press freedom. The ban signals a further tightening of information control on X, with the motivations remaining unclear.

News Overload: How Do I Process Information Effectively?

2025-03-09

The author canceled all daily newspaper subscriptions, keeping only a cooperatively-owned weekly and a French magazine. He finds that more and more online news sites have paywalls, ads, and intrusive scripts, leading him to abandon online news reading. He reflects on the changing attention economy and questions current payment models, finding per-article payments or multiple subscriptions too expensive and impractical. He considers subscribing to the Swiss digital newspaper Republik to support media diversity but struggles to process the vast amount of information effectively. The article concludes with a question about how to process news, reflecting the common dilemma of information overload.

Iron Age Society Centered on Women: Ancient Genomes Reveal a Matrilocal Past

An international team, led by Trinity College Dublin, has unearthed a fascinating glimpse into Britain's Iron Age through ancient DNA. Analysis of over 50 genomes from a Dorset burial site revealed a society structured around female lineage. The study indicates that husbands joined their wives' communities, with land potentially inherited through the maternal line, a system called matrilocality. This pattern wasn't unique to Dorset; similar findings in other Iron Age cemeteries across Britain suggest a widespread phenomenon, challenging traditional views of gender roles and highlighting the significant social and political influence of women in this era. The research published in Nature adds compelling genetic evidence to archaeological observations.

LLVM Static Analyzer Integrates Z3 Solver: Eliminating False Positives

2025-02-23

LLVM's static analyzer now supports the Z3 constraint solver, significantly improving its ability to filter out false positives. The article demonstrates two methods of using Z3: as an external solver and for refuting false positives. The first method, while completely eliminating false positives, is significantly slower (approximately 15x). The second method, using Z3 for refutation, is faster and more efficient in reducing false positives. Experiments show that enabling Z3 allows the LLVM static analyzer to accurately identify and avoid false positives caused by bitwise operations, resulting in more reliable analysis.

Basel Tax Authority Buys Bahamian Web Address Due to Flyer Error

The Basel-Stadt tax authority had to purchase a web address in the Bahamas due to a mistake on an information flyer for digital tax returns. The flyer, sent to over 100,000 households, omitted the '.ch' from the web address, redirecting users to a '.bs' domain in the Bahamas. While the error has been addressed and the Bahamian address will redirect to the correct Swiss site, the mistake cost the authority CHF 900, significantly cheaper than the estimated CHF 100,000 to reprint the flyers. Taxpayers can still file their returns online, albeit with a brief Caribbean detour.

A Java JIT Compiler and Runtime in Common Lisp: OpenLDK

OpenLDK is a Just-In-Time (JIT) compiler and runtime environment for Java, implemented entirely in Common Lisp. It bridges the gap between Java and Common Lisp by incrementally translating Java bytecode into Lisp, then compiling it into native machine code. This unique approach allows seamless mapping of Java classes to Common Lisp Object System (CLOS) classes, enabling effortless integration between Java and Common Lisp codebases. While not designed for high performance, OpenLDK offers a practical solution for integrating Java libraries into a Lisp workflow. Currently, it primarily supports Linux and SBCL, and is a work in progress with many features yet to be implemented, such as support for class files beyond Java 8 and bytecode verification.

Minimal Automatic Differentiation Engine in Rust

This is a minimal automatic differentiation engine written in Rust. It can train a tiny Multi-Layer Perceptron to learn the XOR function and render a computation graph of a single Perceptron to graph.html. The core is the Scalar struct, storing value, optional gradient, and an Edge describing the operation that produced it. Operator overloads and helper functions build a directed acyclic graph, caching the local derivative for every edge. `backward()` recursively propagates gradients from the output node, accumulating them into leaf nodes created with `Scalar::new_grad`. The graph can be visualized with `plot::dump_graph`.
