AI Predicts Dendritic Growth in Thin Films, Paving the Way for Next-Gen Communication

Researchers at Tokyo University of Science have developed a novel AI model that predicts dendritic growth in thin films. Dendritic structures, which negatively impact thin-film device performance, were analyzed by combining persistent homology and machine learning. This allowed researchers to quantify dendritic morphology and link it to Gibbs free energy, revealing specific conditions and hidden growth mechanisms affecting dendritic branching. This research promises to optimize thin-film growth processes, advance beyond-5G high-speed communication technologies, and lead to breakthroughs in sensor technology and high-performance materials.

Google Shifts Android Development Inward, Less Transparency Ahead

Google is changing how it develops Android. All future development will occur in internal branches, shifting away from the previously more public AOSP model. While the final source code will still be publicly released, the development process itself will be less transparent. This aims to streamline releases and simplify development for both Google and Android device manufacturers. The change impacts developers and OEMs, but Google promises improved efficiency.

The Man Who Put the Queen on the Internet

The Man Who Put the Queen on the Internet

Peter Kirstein, a pioneer of the internet, enabled Queen Elizabeth II to become one of the first heads of state to send an email in 1976. He not only set up her email account (username: HME2) but also played a crucial role in bringing the ARPANET, the precursor to the internet, to Great Britain. His efforts in connecting the UK to the ARPANET and promoting the adoption of TCP/IP protocols were pivotal in the development of the global internet. Kirstein's contributions have earned him a place in the Internet Hall of Fame alongside internet luminaries like Vint Cerf, Bob Kahn, and Tim Berners-Lee.

Fearless SIMD in Rust: Seven Years On

2025-03-30

Seven years ago, a blog post outlined a vision for Rust as a compelling language for writing fast SIMD programs. Today, while progress has been made, the experience remains rough. This post explores the challenges of SIMD programming in Rust, focusing on safety concerns, multi-versioning strategies, and future directions. It compares approaches like `std::simd`, `pulp`, and the author's `fearless_simd` prototype, advocating for a collaborative effort within the Rust community to build robust SIMD infrastructure comparable to Highway.

RTABench: A New Benchmark for Real-Time Analytics Applications

Traditional analytics benchmarks often overlook the needs of real-time applications, such as generating fast, targeted insights for specific users, devices, or transactions. RTABench addresses this gap by providing a benchmark that accurately reflects real-time analytics within applications, using a normalized schema, realistic dataset sizes, and queries that match real-world usage patterns. It includes 33 queries covering raw event queries, selective filtering, multi-table joins, and pre-aggregated queries to assess database performance on normalized schemas, selective filtering, and incremental materialized views. RTABench supports multiple databases and welcomes community contributions to expand its database support and optimizations.

Spectral JPEG XL: Crushing Spectral Image File Sizes by 10-60x

Researchers have developed a new technique leveraging JPEG XL to compress spectral images by a remarkable 10 to 60 times, shrinking them to sizes comparable to regular high-quality photos. The method prioritizes discarding less important high-frequency spectral details while preserving metadata and high dynamic range. Although lossy, this approach holds immense potential for scientific visualization and high-end rendering, addressing the storage and transfer challenges posed by massive spectral image files.

It's Time to Stop Building KV Databases

It's Time to Stop Building KV Databases

The author argues that Key-Value databases are overly simplistic and lack expressive power, making them painful to use. While popular among storage engine vendors, KV databases are merely building blocks for reasonable data models, forcing users to build these models from scratch, often with suboptimal results. The author proposes a middle ground: an embedded database with typed records, separating logical and physical schemas but writing queries against the physical schema. This avoids complex query planners, supports asynchronous schema changes and layout switching. This approach balances data independence with the simplicity needed for embedded systems, offering a compelling alternative to both simple KV stores and the complexities of full-blown relational databases.

Apple Shut Out of Google Antitrust Hearing, Facing Multi-Billion Dollar Loss

Apple's attempt to salvage its lucrative search deal with Google has been dealt a blow. A new ruling from the DC Circuit Court of Appeals confirms Apple's exclusion from Google's upcoming antitrust hearing, potentially leaving a multi-billion dollar hole in Apple's balance sheet. Judges cited Apple's late entry into the case. Apple and Google's interests are strongly aligned, with a $20 billion annual deal at stake. Google pays this to be the default search engine in Safari. Government antitrust penalties would make this deal impermissible. The court deemed Apple too slow in choosing sides, filing to participate in the remedy phase 33 days after the initial proposal. While Apple can submit written testimony and amicus briefs, it can't present evidence or cross-examine witnesses.

Banned from MSG for a T-Shirt He Designed Years Ago?

Frank Miller, a graphic designer, was banned for life from Madison Square Garden (MSG) and its properties, including Radio City Music Hall, for an incident he claims he wasn't even involved in. The ban stems from a "Ban Dolan" T-shirt he designed in 2017, referencing a conflict between Knicks owner James Dolan and Charles Oakley. Although Miller wasn't wearing the shirt and hadn't attended an MSG event in almost two decades, he was identified, likely via facial recognition technology, and denied entry to a concert on his parents' anniversary. MSG claims his actions violated their code of conduct, but Miller argues this highlights the potential misuse of facial recognition and corporate power, raising concerns about privacy and surveillance.

Go 1.25 Removes Core Types, Simplifying the Language Spec

2025-03-26

Go 1.18 introduced generics, and with it, the concept of "core types" to simplify handling generic operands. However, this added complexity to the language specification and limited the flexibility of certain operations. Go 1.25 removes core types, replacing them with clearer and more concise rules, thereby simplifying the language specification and opening the door for future language improvements, such as more powerful slice operations and improved type inference. This change does not affect the behavior of existing Go programs.

A Pew Research Center survey across 36 countries reveals significant variations in religious switching rates worldwide. Christianity and Buddhism have experienced particularly large losses, with a rise in religiously unaffiliated adults. In many countries, over one-fifth of adults have left the religion of their upbringing. South Korea shows the highest switching rates, while countries like India, Israel, Nigeria, and Thailand exhibit very low rates. Most switching is towards the religiously unaffiliated category. Age, education, and gender also influence switching rates, with younger and more highly educated individuals often showing higher rates.
