Building a Simple Object System from Scratch in Ruby

2024-12-15

This blog post details building a basic object system in Ruby without using classes. The author cleverly uses anonymous functions and hash tables to implement core OOP concepts like method lookup, prototypal inheritance, mixins, and metaprogramming. Starting with a constructor function, the post demonstrates simulating private variables and public interfaces, effectively recreating class-like behavior and inheritance. Through clear code examples, readers learn to create objects, define methods, implement inheritance and mixins, and even build a rudimentary `attr_accessor`-like metaprogramming feature. It's a practical guide to understanding object system fundamentals.

Philosophical Dead Ends in Evolutionary Theory

2024-12-15

This review examines Richard Dawkins's "The Genetic Book of the Dead" and Sara Imari Walker's "Life as No One Knows It." Dawkins continues his "selfish gene" theory, arguing that genes are the central driving force of evolution. However, the review points out that this view is outdated and fails to adequately consider factors such as development, epigenetics, and niche construction. Walker's book attempts to explain the origin of life from the perspective of assembly theory, but the review argues that it is overly simplistic and fails to fully clarify the essence of life. The article concludes that popular science books often tend towards simplistic narratives, ignoring the complexity and diversity of the field of biology.

Efficient Cloud-Native Raster Data Access: An Alternative to Rasterio/GDAL

2024-12-15

The exponential growth of Earth observation data in cloud storage necessitates efficient access and analysis of satellite imagery. This article introduces an alternative cloud-native raster data access approach to Rasterio/GDAL. Traditional GeoTIFFs are inefficient, while Cloud-Optimized GeoTIFFs (COGs) improve efficiency through tiling and multi-resolution access. However, even with COGs, tasks like time-series NDVI analysis suffer from latency. The authors leverage STAC GeoParquet, combined with pre-calculated byte ranges, to reduce HTTP requests, significantly speeding up data access. Initial tests show this approach drastically reduces time-to-first-tile for Sentinel-2 data and lowers costs. A future open-source library, "Rasteret," will implement these techniques.

Disruptive Country Ranking: The Baby Money Index (BMI) Emerges

2024-12-15

An economics article introduces a new country ranking metric—the Baby Money Index (BMI), which multiplies per capita Gross National Income by the square of the fertility rate. Unlike the traditional Human Development Index (HDI), the BMI focuses more on the long-term impact of population growth on the economy. The article points out that high income and high fertility are difficult to achieve simultaneously; many oil-rich or tax-haven countries top the list, while some developed countries rank lower due to low fertility rates. The United States outperforms any country with a population over 40 million, including the entire G12, due to its high BMI.

The Illusion of Intelligence: AI, Interaction, and the Clever Hans Effect

2024-12-15

This paper explores the nature of intelligence in AI, particularly large language models (LLMs). It argues that the apparent intelligence of LLMs isn't due to independent reasoning but rather emerges from interaction with users. Drawing parallels between Socratic questioning, the Clever Hans effect, and iterative prompting of LLMs, the author demonstrates that intelligence is a relational phenomenon arising from collaboration, not isolated cognition. LLMs generate responses based on probabilistic relationships within their training data, responding to user prompts like Clever Hans responded to his handler's cues. The value of AI, therefore, lies not in its inherent 'knowledge' but in its ability to facilitate insightful questions and collaborative exploration, ultimately augmenting human creativity and problem-solving.
