Mojo: Chris Lattner's Next Big Swing at Revolutionizing Machine Learning Programming

Chris Lattner, creator of LLVM and Swift, discusses his new language, Mojo, with Ron. Mojo aims to make harnessing the full power of modern GPUs productive and fun. The design focuses on making a language easy to use while providing the control needed for state-of-the-art kernel writing. A key concept is requiring programmers to understand hardware details, but making that manageable and shareable through type-safe metaprogramming. The goal is to support specialization for both the computation and the hardware platform. Lattner argues this is necessary to prevent single vendors from dominating the AI computing ecosystem.

Peel-and-Replace Walls: A New Hook-and-Loop System for Concrete

Researchers at Austria's Graz University of Technology have developed a novel hook-and-loop system for concrete walls. Instead of traditional hooks and loops, they cast protrusions into the concrete and 3D print a flexible sheet with corresponding protrusions. This allows for the easy removal and replacement of wall coverings, flooring, and other elements, promising a cleaner, faster, and more efficient approach to construction and renovation.

Nepal Blocks Facebook, X, and YouTube Over Registration Failure

Nepal's government has blocked major social media platforms, including Facebook, X (formerly Twitter), and YouTube, for failing to comply with registration regulations. The government claims repeated notices were ignored. While some platforms like TikTok and Viber, having registered, remain operational, the move has sparked concerns over freedom of speech and accusations that the accompanying bill is a tool for censorship and suppressing dissent.

Amazon's Kuiper to Power JetBlue In-Flight Wi-Fi Starting in 2027

Amazon's Project Kuiper, its satellite internet service, has partnered with JetBlue to provide in-flight Wi-Fi starting in 2027. This marks Kuiper's first airline deal, aiming to compete with SpaceX's Starlink, which already boasts agreements with several major airlines. While Kuiper launched its first satellites in April and now has over 100 in orbit, it's still playing catch-up to Starlink's 8,000+ satellite constellation. Amazon showcased impressive gigabit download speeds using an enterprise-grade terminal, but real-world consumer performance remains to be seen. Initial customer access begins this year, with a wider rollout slated for 2026.

The Diffusion Deficit: Why Transformative Tech Takes So Long

This article explores the often-unexpectedly slow diffusion of transformative technologies, using the tractor as a prime example. It argues that technological success depends not only on inherent superiority but also on compatibility with existing social, economic, and industrial systems. The article examines cases like the telephone, electric motor, and IT, highlighting the need for complementary innovations, skills training, and industrial reorganization to unlock a technology's full potential. The current AI field faces similar challenges, with excessive focus on AGI overshadowing product development and practical application. Ultimately, technological success hinges on understanding and strategizing for diffusion—this is where the true 'technological dividend' lies.

Protocol Buffers: An Amateur Disaster?

2025-09-05

This article criticizes the design flaws of Protocol Buffers (protobuf), arguing that its type system is poor, its design is ad-hoc, and that it leads to a series of problems that permeate the code. The many restrictions of protobuf stem from its poor solutions to already-solved problems, lacking compositionality. Examples include the inability to repeat oneof fields, and various map field limitations. The article also criticizes protobuf's claims of hassle-free backwards and forwards compatibility, and how it pollutes codebases, making code difficult to write and maintain. The author argues that protobuf is only suitable for large companies like Google, not for most companies, and advises developers to abandon the use of protobuf.

Escaping the Nested SQL Query Hell: Building Movie Page Data with a Single Query

2025-09-05

This article discusses the challenges of building movie page data using relational databases. Traditional methods require multiple SQL queries to fetch information such as directors, actors, and genres, and manually assemble the results into the desired hierarchical structure, which is inefficient and prone to errors. The author uses functions such as `jsonb_agg` to directly generate JSON-formatted structured data in a single SQL query, effectively solving the "object-relational impedance mismatch" problem, improving efficiency, and avoiding multiple network requests and data inconsistencies. This demonstrates the evolution of SQL and the importance of adapting to new data needs.

Smartphone Use on the Toilet Linked to Increased Hemorrhoid Risk

A new study suggests a link between smartphone use on the toilet and an increased risk of hemorrhoids. Researchers found that individuals spending extended periods on the toilet scrolling through their phones had a 46% higher risk of hemorrhoid issues. This is attributed to increased rectal pressure from prolonged sitting, leading to swollen veins. Experts recommend minimizing smartphone use in the bathroom and maintaining a healthy diet and hydration to prevent hemorrhoids.

Ultra-Processed Foods: Health Risks and Policy Challenges

The UN is set to discuss a proposal to eliminate trans fats, but experts urge clarification between industrially produced and naturally occurring trans fats to avoid harming nutritious foods. This sparks a broader debate on "ultra-processed foods," often high in sugar, salt, and saturated fat, linked to obesity and cardiovascular disease. While the NOVA classification system helps identify them, its limitations lie in focusing solely on processing, ignoring factors like palatability and calorie density. Therefore, clearer definitions and more precise policies are needed, balancing control over excessive industrial food production with ensuring sufficient and appropriate food for all.

AI Agent Architecture: Trust, Not Accuracy

This post dissects the architecture of AI agents, arguing that user experience trumps raw accuracy. Using a customer support agent as an example, it outlines four architectural layers: memory (session, customer, behavioral, contextual), connectivity (system integrations), capabilities (skill depth), and trust (confidence scores, reasoning transparency, graceful handoffs). Four architectural approaches are compared: single agent, router + skills, predefined workflows, and multi-agent collaboration. The author recommends starting simple and adding complexity only when needed. Counterintuitively, users trust agents more when they're honest about their limitations, not when they're always right.

AI Boosts Gravitational Wave Detection: Deep Loop Shaping Breakthrough

Scientists have used a deep learning technique called Deep Loop Shaping to significantly improve the control precision of the Laser Interferometer Gravitational-Wave Observatory (LIGO), reducing noise by up to 100 times. This technology, using reinforcement learning, optimizes LIGO's feedback control system, enabling it to measure gravitational waves more stably. This helps astronomers delve deeper into the dynamics and formation of the universe, such as detecting more intermediate-mass black holes and studying neutron star collisions in greater detail. This breakthrough is expected to influence the design of future gravitational wave observatories and further expand our understanding of the cosmos.
