US Airlines Push for Deregulation, Threatening Passenger Rights

Major US airlines, including American, Delta, Southwest, and United, are pushing for deregulation, claiming it will lower costs and boost competition. However, this move risks significantly eroding passenger rights and increasing hidden fees. Key protections at stake include automatic refunds for cancellations, transparent pricing, and guaranteed family seating. While airlines argue deregulation will lower fares, the likely outcome is more fees, less accountability for service failures, and a diminished sense of consumer protection. This could lead to a more expensive and opaque air travel experience for passengers.

API Churn vs. Security: The Perils of Client-Side Heavy Logic

This article explores the problems stemming from the current trend of heavy client-side logic in web applications, namely API churn. While solutions like GraphQL offer more expressive APIs, mitigating the resulting security risks – where increased client-side power empowers malicious users – becomes incredibly complex. The author argues that moving logic back to the server side is the best approach to avoid this trade-off between API churn and security complexity.

CERN Releases Feasibility Study for Future Circular Collider

After years of intense work, CERN and its international partners have completed a feasibility study for a Future Circular Collider (FCC). The report details various aspects of the potential project, including physics goals, engineering, environmental impact, and cost. The FCC proposes a roughly 91-km circumference particle collider to succeed the Large Hadron Collider (LHC) in the 2040s. Key scientific goals include deeper investigation of the Higgs boson and other fundamental particles, aiming to unlock the universe's secrets. The report estimates the cost of the FCC's electron-positron collider stage at 15 billion Swiss francs, with construction taking about 12 years. The project emphasizes sustainability and public engagement. The report will be reviewed by the CERN Council, which is expected to decide on the FCC's future around 2028.

Rust's `fetch_max`: A Deep Dive into Compiler Optimization

During a recent engineering interview, a candidate used a single line of Rust code to solve a classic concurrency problem—tracking the maximum value across multiple producer threads. This sparked the author's curiosity: how does Rust's `fetch_max` actually work? The article delves into the compilation process from Rust code to assembly, revealing the layers of optimization involving macros, LLVM intermediate representation, compiler intrinsics, and target architecture specifics. On x86-64, `fetch_max` compiles down to a compare-and-swap (CAS) loop; on ARM, it directly utilizes the hardware's atomic max instruction. This article demonstrates the power of modern compilers and the low-level details behind high-level abstractions.

LLMs: Manipulating Symbols or Understanding the World?

This article challenges the prevailing assumption that Large Language Models (LLMs) understand the world. While LLMs excel at language tasks, the author argues this stems from their ability to learn heuristics for predicting the next token, rather than building a genuine world model. True AGI, the author contends, requires a deep understanding of the physical world, a capability currently lacking in LLMs. The article criticizes the multimodal approach to AGI, advocating instead for embodied cognition and interaction with the environment as primary components of future research.

The Collatz Conjecture and Cryptography: A Tale of Computational Complexity

This article explores the infamous Collatz conjecture and its surprising connection to ARX algorithms in cryptography (e.g., ChaCha). The Collatz conjecture describes a simple iterative function; whether it always converges to 1 remains unproven. The article draws an analogy between the Collatz function and a Turing machine, highlighting how carry propagation in its bitwise implementation creates unpredictable complexity. This contrasts interestingly with ARX algorithms, which use addition, rotation, and XOR to achieve efficient diffusion. The article suggests the Collatz conjecture's unsolved nature might stem from the inherent complexity of computation, similar to the halting problem.

Cryptographic Security Shaken: Attack on Fiat-Shamir Transformation

New research has challenged the long-held assumption of the random oracle model in cryptography. Researchers demonstrated a method to trick proof systems using the widely adopted Fiat-Shamir transformation, enabling them to certify false statements. This transformation is crucial in systems like blockchains for verifying computations from external servers, relying on the random oracle model's assumption. The research shows that even under this assumption, attacks are possible. This finding necessitates a re-evaluation of the random oracle model and its implications for numerous cryptographic applications, raising concerns about blockchain security and the potential for cryptocurrency theft.

This blog post introduces pahole, a powerful tool for analyzing the memory layout of C/C++ data structures, including padding and alignment details. By reading the DWARF debugging information generated by the compiler, pahole visually displays how data structures are arranged in memory and points out "holes" inserted by the compiler to meet memory alignment requirements. This is crucial for optimizing code cache utilization and reducing cache line false sharing. The post also demonstrates how to install pahole and how to use its command-line options to analyze struct sizes, adjust member ordering to optimize memory layout, and explore memory layout differences under different cache line sizes.

Court Rules Against Trump's Tariffs: A Case of Overreach?

2025-05-29

A US trade court recently ruled against Donald Trump's tariffs, citing a violation of constitutional authority. The court found that the Trump administration exceeded its power under the International Emergency Economic Powers Act (IEEPA) of 1977. Both the 'worldwide retaliatory tariffs' and 'trafficking tariffs' were deemed unlawful; the former for being overly broad, the latter for lacking a demonstrable link to drug trafficking. The decision hinges on the Constitution's grant of foreign trade regulation power to Congress, and the limitations on delegation of that power as defined by the nondelegation doctrine. The Trump administration has appealed the decision, setting the stage for further legal battles over executive versus legislative power.

From Random Streaks to Recognizable Digits: Building an Autoregressive Image Generation Model

This article details building a basic autoregressive image generation model using a Multilayer Perceptron (MLP) to generate images of handwritten digits. The author explains the core concept of predicting the next pixel based on its predecessors. Three models are progressively built: Model V1 uses one-hot encoding and ignores spatial information; Model V2 introduces positional encodings, improving image structure; Model V3 uses learned token embeddings and positional encodings, achieving conditional generation, generating images based on a given digit class. While the generated images fall short of state-of-the-art models, the tutorial clearly demonstrates core autoregressive concepts and the building process, providing valuable insights into generative AI.
