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.

Iron Age Society Centered on Women: Ancient Genomes Reveal a Matrilocal Past

Iron Age Society Centered on Women: Ancient Genomes Reveal a Matrilocal Past

An international team, led by Trinity College Dublin, has unearthed a fascinating glimpse into Britain's Iron Age through ancient DNA. Analysis of over 50 genomes from a Dorset burial site revealed a society structured around female lineage. The study indicates that husbands joined their wives' communities, with land potentially inherited through the maternal line, a system called matrilocality. This pattern wasn't unique to Dorset; similar findings in other Iron Age cemeteries across Britain suggest a widespread phenomenon, challenging traditional views of gender roles and highlighting the significant social and political influence of women in this era. The research published in Nature adds compelling genetic evidence to archaeological observations.

Framework Fatigue: Why Developers Are Angry About New Tech

The constant stream of new JavaScript frameworks—from Svelte to Solid to Qwik—has left developers exhausted. Each promises blazing speed and improved performance, yet developers find themselves in a perpetual cycle of learning, consuming precious time and energy. This has sparked heated debates, with some arguing that new frameworks reinvent the wheel, while others express fears about job security and the obsolescence of existing skills. The article suggests that developer anger towards new frameworks is a self-defense mechanism stemming from anxieties about future career prospects. Understanding this perspective can foster healthier industry evolution.

Bio-Inspired Adaptive Shading: Energy-Autonomous & Sustainable

2025-01-21

Researchers at the Universities of Stuttgart and Freiburg have developed a novel energy-autonomous building facade shading system, "Solar Gate," inspired by pine cones. Using bio-based cellulose materials and 4D printing, the system passively adjusts shading based on humidity and temperature changes, requiring no electricity. It closes in summer to minimize solar radiation and opens in winter to maximize sunlight for natural heating, offering a sustainable and efficient solution for climate control in buildings.

Redis UNLINK vs DEL: A Deep Dive into Internal Mechanics

Redis UNLINK vs DEL: A Deep Dive into Internal Mechanics

Both Redis' UNLINK and DEL commands remove keys, but their internal implementations differ. DEL synchronously deletes keys and frees memory, while UNLINK asynchronously queues the deletion for background processing. UNLINK's 'non-blocking' nature isn't absolute; it calculates the cost of deleting an object: if the cost is less than 64, it deletes synchronously; otherwise, asynchronously. The article delves into the Redis source code, explaining the implementation details of UNLINK and DEL, including key slot calculation, two-phase unlinking, and asynchronous deletion, and discusses the role of LAZYFREE_THRESHOLD.

LLMs: Lossy Encyclopedias

2025-09-02

Large language models (LLMs) are like lossy encyclopedias; they contain a vast amount of information, but this information is compressed, leading to data loss. The key is discerning which questions LLMs can answer effectively versus those where the lossiness significantly impacts accuracy. For example, asking an LLM to create a Zephyr project skeleton with specific configurations is a 'lossless' question requiring precise details, which LLMs struggle with. The solution is to provide a correct example, allowing the LLM to operate on existing facts rather than relying on potentially missing details within its knowledge base.

The Century-Long Keyboard War: QWERTY vs. Dvorak

This essay delves into the century-long history of the QWERTY and Dvorak keyboard layouts. QWERTY, far from being random, was ingeniously designed to solve mechanical limitations in early typewriters. Dvorak, conversely, aimed for efficiency and ergonomics. Despite Dvorak's demonstrated advantages in trials, historical factors like market inertia, switching costs, and a lack of sustained marketing prevented its widespread adoption. The article reveals the intricate interplay of technological progress, market forces, and human biases in shaping keyboard layouts, prompting reflection on technology standard selection and market competition.

Next.js Logging Nightmare: A Struggle with Production Logging

The author encountered a series of challenges while attempting to add production logging to a Next.js service. Next.js's middleware mechanism is heavily restricted, and AsyncLocalStorage couldn't bridge the rendering context, resulting in logging failures in pages and layout components. The author tried various methods, including a custom server, ultimately discovering that Next.js's design limited the implementation of logging features. A comparison with SvelteKit highlights Next.js's shortcomings in logging and the inefficiency of its GitHub issue tracker.
