AI Robot: Fairy Tale vs. Reality

This article contrasts the fictional AI robot 'Robot' from Annalee Newitz's story with the real-world clumsy CIMON, exploring the limitations of current AI. Robot, capable of independent learning and exceeding its programming, showcases the potential of Artificial General Intelligence (AGI). In contrast, CIMON's limited Artificial Narrow Intelligence (ANI) reveals its rigid nature. The author points out that current AI technology largely remains in the ANI stage, vulnerable to algorithmic bias and unable to adapt to complex situations as Robot does. While machine learning has made strides in language processing and image recognition, achieving AGI remains a distant goal. The author urges caution against over-reliance on biased training data and emphasizes the importance of self-learning and feedback mechanisms in AI development. Strive for Robot, plan for CIMON.

CAPTCHA is Dead: The Ticketing Industry's Bot War

2025-05-25

Ticketing websites face a persistent challenge: bots used by scalpers to snatch tickets. Traditional CAPTCHAs, such as image and audio recognition, have been defeated by advanced machine learning. Behavior-based anti-bot technologies, while effective, compromise user privacy; while proof-of-work methods are too inexpensive for scalpers. The author proposes a "BAP theorem," stating that anti-bot systems can only satisfy two out of three properties: "bot-resistance," "accessibility," and "privacy." Ultimately, websites must choose between high privacy and high security; technical solutions alone are insufficient. Legislation and social approaches might be more effective.

Optimizing JS Config Objects with BigInts: An Experiment

To optimize serialization, comparison, and update operations on a large number of configuration objects, the author experimented with using JavaScript's BigInt type to store configuration data. By packing multiple configuration fields into a single BigInt and using bitwise operations for efficient read and write operations, the author achieved a compact memory representation and fast serialization/deserialization. However, this approach also has some drawbacks, such as the need to manually manage field bit widths and offsets, and the performance issues of BigInt bitwise operations. The author is currently still evaluating the practical effect of this method and plans to update the article in the future.

Deterministic Finite Automata Resonating with Physics Models

2025-04-25

This article details the construction of deterministic finite automata (DFAs) using simple rules based on fundamental computer science concepts like trees, edges, and binary strings. The author outlines a five-step process, resulting in two main DFA variations that resonate with physics models—one including black holes and white holes, the other only black holes. By mapping binary strings to physical phenomena (inflation, black holes, white holes, entropy), a model for cosmic evolution is proposed. Connections to quantum mechanics and other disciplines are explored, highlighting the deep interplay between computer science, mathematics, and physics.

Fusing Unreliable Sensor Readings: Beyond Linear Mixing

Fusing Unreliable Sensor Readings: Beyond Linear Mixing

This article explores fusing measurements from two unreliable sensors for improved accuracy. Sensor A's readings contain noise, while Sensor B has a probability of outputting either the correct value or noise. The author first tries a linear weighted average, finding the optimal weight isn't 50/50, but around 0.58. Then, a threshold based on the difference between sensor readings is used; if the difference is below the threshold, Sensor B's reading is used, otherwise Sensor A's. This significantly improves accuracy. Finally, by adding a middle zone where a linear mix of both readings is used, further optimization is achieved, lowering the mean absolute error to 0.1163.

Layered Design in Go: A Weapon Against Circular Dependencies

2025-04-20

This post delves into the problem of circular dependencies in Go and offers solutions. The author points out that Go's prohibition against circular package imports inherently shapes program design, promoting a layered architecture. Analyzing package import relationships allows for decomposition into layers, where higher-level packages depend on lower-level ones, preventing circularity. Several refactoring techniques for handling circular dependencies are introduced, including moving functionality, creating new packages, and using interfaces. Minimizing exported package members is stressed. This layered approach not only avoids circular dependencies but also enhances code understandability and maintainability, making each package independently useful.
