Kelly Can't Fail: A Zero-Variance Gambling Game

This article presents a card game called "Next Card Bet," where the Kelly betting strategy, typically known for its high variance, surprisingly exhibits zero variance. By counting the remaining red and black cards, the player calculates the optimal bet fraction to maximize the expected logarithm of their stake. Python simulations demonstrate consistent returns of approximately 9.08 times the initial stake across 10,000 runs, showing no variance. The article explains this zero-variance property by showing the Kelly strategy's equivalence to a portfolio strategy that distributes bets across all possible card arrangements. This portfolio strategy guarantees a specific return, independent of the card order, thus explaining the zero variance of the Kelly strategy in this unique game.

Apple Paper Exposes Limits of Scaling in Large Language Models

An Apple paper highlighting limitations in the reasoning capabilities of large language models (LLMs) has sparked a heated debate in the AI community. The paper demonstrates that even massive models struggle with seemingly simple reasoning tasks, challenging the prevalent 'scaling solves all' hypothesis for achieving Artificial General Intelligence (AGI). While some attempted rebuttals emerged, none proved compelling. The core issue, the article argues, is LLMs' unreliability in executing complex algorithms due to output length limitations and over-reliance on training data. True AGI, the author suggests, requires superior models and a hybrid approach combining neural networks with symbolic algorithms. The paper's significance lies in its prompting a critical reassessment of AGI's development path, revealing that scaling alone is insufficient.

C++ shared_ptr's Non-Atomic Reference Counting: A Microbenchmark Surprise

A microbenchmark comparing Rust and C++ data structures revealed unexpected behavior in C++'s `shared_ptr`. In single-threaded environments, GNU libstdc++ optimizes `shared_ptr`'s reference counting to be non-atomic if `pthread_create` isn't imported. This performance optimization, while generally safe, can lead to issues in uncommon scenarios, such as when a dynamically linked library is loaded by a statically linked program. The author investigated other C++ implementations (libcxx and Visual C++) and ultimately resolved the performance discrepancy by referencing `pthread_create` in their benchmark. The discovery highlights the complexities of low-level optimizations and their potential unintended consequences.

Pi is not Constant: Exploring π in Non-Euclidean Spaces

This article explores the value of pi (π) in various metric spaces. By altering the distance formula in Euclidean geometry, a series of non-Euclidean spaces are constructed, and the ratio of circumference to diameter of 'circles' in these spaces is calculated. The results show that while in standard Euclidean space (n=2), π is approximately 3.14159, its value changes in other spaces. For instance, in taxicab geometry (n=1) and Chebyshev distance (n→∞), π equals 4. This demonstrates that π's value isn't constant but depends on the underlying geometry of the space.
