Art-Inspired Discovery: The Third Kind of Magnetism

Inspired by M.C. Escher's artwork, physicist Libor Šmejkal predicted and confirmed a third type of magnetism – altermagnetism. Unlike ferromagnetism and antiferromagnetism, altermagnets have atomic magnetic moments pointing in opposite directions but with a 90-degree rotation, resulting in unique quantum properties. This new magnetism promises to solve challenges in spintronics, leading to more efficient and faster computer memory. Researchers have confirmed altermagnetism in manganese telluride and are exploring more such materials, even predicting a fourth type: antialtermagnetism.

Nvidia's H20 AI Chips Flood Back into China, Spurring a Rush of Orders

Reuters reports that Chinese firms are scrambling to order Nvidia's H20 AI chips as the company prepares to resume sales to mainland China. Nvidia expects imminent US government licenses to restart shipments of the restricted processors, just days after CEO Jensen Huang met with President Trump, potentially adding $15 billion to $20 billion in revenue this year. This surge follows the 2022 launch of ChatGPT, highlighting the link between Nvidia's financial success and the demand for specialized hardware to efficiently power AI models. While the H20 chips are Nvidia's most powerful legally available in China, they are less potent than versions sold elsewhere due to 2022 export restrictions; Nvidia remains banned from selling its most powerful GPUs in China.

The Legend of Mel: A Real Programmer's Hexadecimal Blackjack

2025-07-16

This article recounts the story of Mel, a legendary programmer from the 1980s. A master of machine code, Mel wrote a blackjack game for the LGP-30 computer at Royal McBee, later optimizing it for the RPC-4000. He eschewed compilers and optimizing assemblers, manually optimizing code to exploit the drum memory architecture for maximum speed. Even simple loops were ingeniously crafted, using instruction address overflow to terminate, avoiding explicit tests. While forced to add a win/loss switch, he subtly reversed the logic, making the program always win when activated, showcasing his unique style and ethical stance. The article highlights Mel's profound skill and dedication to his craft.

The Secret to Faster, More Accurate Code: Mental Code Proofs

2025-07-16

This article unveils a technique for writing code faster and more accurately: performing "online" proofs. Instead of interrupting your coding flow, mentally prove your code's correctness as you write. The author details several strategies to aid in this process, including focusing on code monotonicity, utilizing pre- and post-conditions, maintaining invariants, and isolating the impact of changes. Inductive reasoning for recursive functions and data structures is also highlighted, along with advocating for "proof-affinity" as a code quality metric. Finally, the author suggests practicing mathematical proofs to sharpen your code-proving skills.

H-Nets: A Hierarchical Network Architecture That Outperforms Transformers

Current AI architectures treat all inputs equally, failing to leverage the inherent hierarchical nature of information. This limits their ability to learn from high-resolution raw data. Researchers introduce H-Nets, a novel architecture that natively models hierarchy directly from raw data. H-Nets' core is a dynamic chunking mechanism that segments and compresses raw data into meaningful concepts. Experiments show H-Nets outperform state-of-the-art Transformers in language modeling, exhibiting improved scalability and robustness, offering a promising path towards multimodal understanding, long-context reasoning, and efficient training and inference.

High-Performance Dynamic Dispatch with GLIBC hwcaps

2025-07-16

This article demonstrates how to leverage GLIBC 2.33+ hwcaps for simple dynamic dispatch in amd64 and POWER shared libraries. By creating library files for different CPU instruction sets (e.g., x86-64-v4, x86-64-v3, etc.) under `/usr/lib/glibc-hwcaps/`, the dynamic linker automatically loads the corresponding library based on the highest instruction set supported by the CPU, optimizing performance. This solves the challenge of maintaining consistent library performance across different CPU architectures, as demonstrated in the Debian packaging of the ggml library used by llama.cpp and whisper.cpp.
