Efficiency vs. Horizontal Scalability: A Necessary Trade-off?

2025-02-12

Efficiency vs. Horizontal Scalability: A Necessary Trade-off?

This article explores the tension between software efficiency and horizontal scalability. The author argues that software optimized for scalability often performs poorly in single-machine environments, and vice versa. This stems from Amdahl's Law, coordination overhead, and limitations on shared resources. Efficient algorithms often rely on assumptions about the system and problem that may no longer hold true when scaling horizontally. The author also discusses cultural factors and task types influencing choices, illustrating with examples like the Tigerbeetle database and CPython's GIL. Ultimately, a deep understanding of the problem and environment is key to achieving both high efficiency and scalability.

Scientists 'Write' New Information into the Human Brain Using MRI

2024-12-19

Scientists 'Write' New Information into the Human Brain Using MRI

Researchers from the University of Rochester, Yale University, and Princeton University have developed a novel technique to induce learning by directly manipulating brain activity patterns. Using real-time brain imaging and neurofeedback, this method bypasses traditional learning processes that require effort and practice. Participants in an fMRI machine were presented with 'wobbling' abstract shapes and instructed to stop the movement using only their minds. A pre-defined brain activity pattern associated with a new visual category was linked to cessation of the wobble. This feedback mechanism effectively 'sculpted' the participants' brain activity, leading them to learn new visual categories without conscious awareness. This groundbreaking technology holds immense potential for applications in education, rehabilitation, and mental health treatments.

The Misunderstood Usefulness of `font-size-adjust`

2025-07-26

This article challenges the common misconception surrounding the CSS property `font-size-adjust`. The author argues that `font-size` specifies the size of the box around a glyph, not the glyph itself, leading to inconsistencies across different fonts. Instead of solely focusing on font fallback, `font-size-adjust` can be used to ensure more consistent sizing across various fonts on a page. The author recommends setting it to `ex-height 0.53` in a CSS reset for improved typographic consistency.

Toxic Origins, Toxic Decisions: Bias in CEO Selection

New research reveals selection bias in CEO promotion amplifies risk-taking. CEOs born near future Superfund sites (exposed to prenatal pollution) are more likely to be promoted internally, suggesting firms reward apparent success without considering inherent risk tolerance. These 'Superfund CEOs' excel internally but pursue riskier external policies after promotion, leading to greater volatility and weaker performance. The study indicates firms may mistake luck for skill, inadvertently selecting high-variance risk-takers whose traits only become detrimental when decision-making shifts to public, irreversible domains.

LLMs Fail at Set, Reasoning Models Triumph

An experiment tested the reasoning capabilities of Large Language Models (LLMs) in the card game Set. Set requires identifying sets of three cards from a layout of twelve, based on specific rules regarding shape, color, number, and shading. LLMs like GPT-4o, Sonnet-3.5, and Mistral failed to consistently identify correct sets, often suggesting invalid combinations or claiming no sets existed. However, newer reasoning models, DeepThink-R1 and o3-mini, successfully solved the problem, demonstrating superior logical reasoning abilities. This highlights a limitation of LLMs in complex logical tasks, even while excelling at natural language processing, while specialized reasoning models show a clear advantage.

Newtonianism for Ladies: Science, Fashion, and a Dash of Controversy

2025-09-21

Algarotti's *Il Newtonianismo per le dame* uses a dialogue between a narrator and a Marchioness to explain Newtonian physics, cleverly blending scientific education with entertainment. Poems dedicated to prominent figures and a lighthearted approach to optics, rather than mechanics, characterize the text. While seemingly promoting female scientific literacy, the portrayal of the Marchioness's understanding sparks debate: some see her as a passive recipient of knowledge, while others highlight the book's depiction of a woman's curiosity about science alongside fashion.
