DeepGEMM is a CUDA library offering efficient FP8 matrix multiplications with fine-grained scaling, supporting both normal and Mix-of-Experts GEMMs. The lightweight library matches or exceeds performance of expert-tuned libraries, featuring runtime compilation and Hopper tensor core optimization, while maintaining a simple ~300-line core kernel.
Physicists are exploring the chaotic nature of space-time near black hole singularities using new mathematical tools and the AdS/CFT correspondence. Recent research revisits the Mixmaster universe theory from the 1960s, suggesting that space near singularities experiences chaotic stretching and compression in multiple directions. These studies aim to reconcile general relativity with quantum mechanics and potentially reveal fundamental truths about space-time.
Browser-use is a Python library enabling AI agents to control web browsers through natural language commands, supporting automated tasks like web browsing and form submissions. The project aims to advance browser automation capabilities while establishing best practices for UI/UX design in the age of AI agents.
A critical analysis of common conference talk patterns suggests alternatives like distillation of complex knowledge, adversarial collaboration, replication studies, and failure analysis. The piece advocates for more substantive presentations that systematize knowledge, verify claims, and share valuable lessons from failures rather than superficial project updates or product pitches.
A personal account details the development of the XB-70 Valkyrie supersonic bomber through the lens of a father's career at General Electric during the Cold War. The ambitious aircraft project, despite its technological advances, was ultimately reduced from a strategic bomber program to a research vehicle due to the rise of ballistic missiles. The narrative weaves together family history, technological innovation, and Cold War politics while following the father's professional evolution from farm boy to engineer.
Federal funding of scientific research, including seemingly obscure projects, consistently yields high returns with estimates suggesting $14-70 in social benefits per dollar spent. Government-funded basic research often leads to unexpected breakthroughs, like CRISPR and ARPANET, taking approximately 20 years from discovery to practical application. Private sector cannot effectively fund basic research due to long timelines and inability to capture full value, making government funding crucial for scientific advancement.

Language models can effectively perform listwise document ranking, particularly useful in identifying N-day vulnerabilities through patch diffing. The technique transforms complex security problems into document ranking tasks, demonstrated successfully in locating vulnerable functions among patch diffs using GPT-4 mini with minimal cost and time.
Framework, known for modular laptops, announces its first desktop PC featuring AMD Ryzen AI Max processor and Radeon 8060S integrated GPU. The compact Framework Desktop, targeting power users seeking maximum performance in minimal space, is scheduled to ship in Q3 2025 with pre-orders starting immediately.
Chicory is a JVM native WebAssembly runtime implemented entirely in pure Java, requiring no system resources. The runtime offers easy integration capabilities for plugin systems while maintaining security through sandboxed execution of WebAssembly modules.
Scientists propose that wolves may have domesticated themselves into dogs by choosing to stay near humans for food and selecting mates with similar tameness preferences. A new statistical model demonstrates this self-domestication could have occurred over 15,000 years through natural selection, challenging previous assumptions about human-driven domestication.
A legal battle over database schema access through FOIA requests in Illinois reached the state Supreme Court, ultimately ruling that schemas could be withheld as 'file layouts.' New legislation (SB0226) aims to require public bodies to provide database structure descriptions, enabling citizens to request specific database queries.
Optifye.ai, a Y Combinator-backed startup founded by Duke University students, introduces AI-powered surveillance system for monitoring factory workers' productivity through machine vision tracking. The system allows supervisors to monitor workers' hand movements and efficiency metrics in real-time, raising concerns about worker privacy and workplace conditions. Y Combinator has since removed promotional posts about the company's launch.
DeepSearcher is an open-source research agent that builds upon previous work by adding features like conditional execution flow, query routing, and improved interfaces. The system leverages SambaNova's custom hardware for faster inference with the DeepSeek-R1 model, demonstrating advanced concepts in AI research automation through a four-step process of question definition, research, analysis, and synthesis.

David E. Weisberg chronicles the 80-year evolution of Computer-Aided Design (CAD) through extensive interviews with industry pioneers and detailed company histories. The comprehensive 650-page document covers CAD's development from its 1950s origins through the early 2000s, offering insights into the technology, companies, and individuals who revolutionized engineering design.
Mathematical advances in 'landscape function' theory have significantly improved LED light bulb efficiency, leading to substantial energy savings in US households. The technology enables more accurate simulation of LED designs, particularly helping solve the 'green gap' problem through V-shaped defects in semiconductor layers. US consumers are projected to save $890 billion by 2035 through LED adoption.
Hyperspace, a new Mac app developed to leverage APFS clone files functionality, helps users reclaim disk space by converting duplicate files into clones that share a single data instance. The app represents a significant advancement in file system management, allowing space savings without deleting files, and is now available on the Mac App Store as a free download with paid features.
A person's critical medical condition was identified by ChatGPT through analyzing lab results showing zero platelets, leading to a timely ER visit and emergency treatment. The AI served as a crucial intermediary between patient and healthcare system, demonstrating its potential as a life-saving medical translator and decision support tool.
Federal employees were requested to submit bullet points of their weekly accomplishments, with responses potentially being analyzed by AI to determine job necessity. The directive, initiated by Elon Musk, faced significant pushback from various agencies and unions, while receiving praise from President Trump. Multiple government departments instructed their employees not to respond, citing security and confidentiality concerns.
