Deconstructing Complex Systems with Mereology: Beyond Simple Causality

2025-02-06

This article presents a novel approach to understanding higher-order structure in complex systems, based on mereology, a branch of set theory. Using the Borromean rings as an example, it illustrates how the whole can be more than the sum of its parts. The author proposes that by constructing a system's mereology and applying the Möbius inversion formula, macroscopic quantities can be decomposed into sums of microscopic contributions, revealing the nature of higher-order interactions. Examples from gene interactions and mutual information in information theory demonstrate the method's application, with promising implications for machine learning and physics.

OpenAI's o3 Model: Hype vs. Reality

OpenAI's o3 model sparked controversy after its performance on the ARC-AGI benchmark was interpreted by some as a breakthrough towards AGI. However, expert Gary Marcus argues the test was misleading: o3 received extensive pre-training, unlike human learning; presented graphs selectively highlighted progress, exaggerating the achievement; ultimately, o3's performance doesn't represent true AGI, and the media's hype is criticized.

AI: The Next Cloud Computing?

2025-01-21

This article draws a parallel between the current AI boom and the cloud computing wave of 20 years ago. The author argues that while AI, particularly Large Language Models (LLMs), shows immense potential, its development path remains uncertain, much like the early days of cloud computing where many predictions failed to materialize. The author points out that AI's success relies on deep learning, powerful computing resources, and massive datasets, but it also faces challenges such as model size, energy consumption, data bias, and copyright issues. He suggests that the future direction of AI may go beyond current expectations and requires incorporating research from fields like cognitive science for a more comprehensive understanding and application of AI.

OpenAI Outage: Unexpected Load from New Telemetry Service Causes Major Disruption

OpenAI experienced a major service disruption on December 11th, stemming from a newly deployed telemetry service. Intended to improve reliability, this service unexpectedly generated massive Kubernetes API server load, saturating the servers and causing the Kubernetes control plane to fail in most large clusters. This led to the breakdown of DNS-based service discovery. The incident highlights the unpredictable interactions within complex systems and the challenges of testing for failure modes that only appear under full load. OpenAI restored service by scaling down clusters, blocking network access to Kubernetes admin APIs, and scaling up API servers.

A Programmer's Lesson: Always Bundle a Proposal with a Complaint

In 1988 at Apple, a young, cocky engineer, Kent Beck, was summoned to Jean-Louis Gassée's office after sending an email complaining about a company decision. Instead of anger, Gassée challenged Beck to consider his perspective and rewrite the email as a proposal for a solution. This experience taught Beck three valuable lessons: most problems aren't as big as they seem; always include a solution with a complaint; and effective communication requires empathy. This anecdote highlights crucial workplace communication skills and the importance of understanding different viewpoints.

California's Minimum Wage Hike: A Surprise Success

California's Minimum Wage Hike: A Surprise Success

California's September 2023 law raising the minimum wage for fast-food workers to $20 per hour faced immediate backlash, with predictions of widespread job losses and business closures. However, these predictions proved false. Since the law's April implementation, California's fast-food sector has seen job growth exceeding the national average. Economists' analyses revealed that increased wages didn't decrease employment; instead, reduced employee turnover and increased productivity lowered labor costs for employers. While prices rose, the increase was far less than anticipated, significantly outweighed by the wage increase for workers. This challenges assumptions about minimum wage impacts, highlighting biases in economic understanding and the role of media in disseminating misinformation.

US Air Crash: Outdated Tech, Not Diversity Hiring, is the Culprit

2025-02-01

Following a recent collision between an American Eagle jet and a Black Hawk helicopter, various narratives have emerged. Some blame diversity hiring for unqualified air traffic controllers, while others suggest closing Washington National Airport. However, the article argues the real culprit is the severely outdated US air traffic control system: antiquated equipment, cumbersome manual processes, and decades of failed technology upgrades. The article reveals that the FAA's technological issues far outweigh the impact of diversity hiring, with its self-regulation and inefficient procurement systems also being significant factors. The FAA's outdated technology and inefficient management are the root causes of frequent air accidents and staffing shortages.

This article explores performance optimization of compiler data structures by flattening Abstract Syntax Trees (ASTs). The author builds a simple arithmetic expression interpreter, implementing it both with traditional pointers and a flattened array approach, comparing their performance. Results show a 2.4x speedup with the flattened version, attributed to improved memory locality, smaller reference sizes, and cheaper allocation/deallocation. Flattening also simplifies memory management and facilitates deduplication. The article further presents an iterative interpreter exploiting the flattened representation for additional performance gains.

Ada's Dependent Types: An Unexpected Coincidence

Ada's Dependent Types: An Unexpected Coincidence

This article explores the lesser-known dependent types feature in the Ada programming language. The author argues that Ada's design goal of avoiding unnecessary dynamic memory allocation led to its unique implementation of dependent types: using a second non-call stack to return data of unknown compile-time size, cleverly circumventing the need for dynamic allocation. This unexpectedly coincides with the formal definition of dependent types, showcasing an unforeseen serendipity in Ada's design. The article further explains concepts in Ada's type system such as derived types, subtypes, discriminated records, and type predicates, demonstrating how these features enable the implementation of dependent types. Finally, the author discusses the interesting interplay between Ada's design philosophy and academic research on type theory, suggesting that many of Ada's type system features didn't originate directly from type theory research, but rather evolved naturally to meet specific needs.
