The article by Jared Wilber & Lucía Santamaría discusses the process of using a Decision Tree to classify trees based on their Diameter and Height. They illustrate this with a hypothetical scenario where, after making an initial classification based on Diameter, subsequent splits are made according to Height and other features to refine the classifications into Apple, Cherry, and Oak trees. While splitting the data into more specific regions can lead to better classification, there's a risk of overfitting the model to the training data, making

Andrej Karpathy created a 200-line Python script that trains a GPT model from scratch using pure Python, without any libraries. The script includes the core algorithm that drives large language models (LLMs) like ChatGPT. It trains on a dataset of 32,000 human names, aiming to learn their statistical patterns to generate new, plausible names. During training, the model outputs names such as "kamon" and "anton," showcasing its understanding of which characters commonly follow others and the typical

The content discusses the need for a non-blocking way to check for pending messages in Ractor-based architectures, addressing limitations of the current Ractor API. It highlights that the existing Ractor#receive method blocks threads until a message arrives, hindering integration with cooperative multitasking systems. Developers are left with either accepting thread blocking or creating complex workarounds. To resolve these issues, the proposed solution is to introduce a new method, Ractor#empty?, which would allow developers to check if

The author proposes a truce in the ongoing debate about AI risks, particularly focusing on terms like "the singularity," "superintelligence," and "doomers." They argue that the prevailing question shouldn't be about the worst-case scenarios but rather about the real, tangible risks of current AI technologies, which don't require superintelligence to pose significant threats. The author insists that people should be able to acknowledge these risks without being dismissed by either "denialists" or "doomers." They stress

A guilty pleasure is a liking for something that contradicts one's self-image, such as enjoying Paris Hilton despite feeling one shouldn't. Conversely, a guilty displeasure is disliking something one feels obliged to appreciate due to their identity or aspirations. The author shares personal examples of guilty displeasures, such as opera, old movies, and poetry, noting a lack of genuine enjoyment for these "high culture" forms despite a preference for classical music and literature. They illustrate their feelings by describing experiences like attending oper

The author reflects on their experience managing microservices at Qantas and the challenges of maintaining synchronization and managing codebase complexity. A key strategy they implemented was adopting Polylith alongside Clojure, focusing on simplicity through composition and data, aiming to combat "accidental complexity" in software development. They draw parallels between their past challenges and current struggles faced by LLM coding agents, emphasizing that the choice of programming language significantly impacts managing complexity. The author references Fred Brooks' 1986 essay "No

The content discusses "xmloxide," a pure Rust reimplementation of the widely-used XML/HTML parsing library libxml2, which became unmaintained in December 2025 due to security issues. Xmloxide aims to be a memory-safe and high-performance alternative that maintains compliance with the same conformance tests as libxml2. Key features and performance metrics include: - Competitive parsing throughput, with improvements of 12% faster on SVG documents. - Faster serialization capabilities (1.5-

The author expresses mixed feelings about the popularity of their precision clock kits, mentioning their previous anxiety about making mistakes while working. This anxiety limited their ability to listen to media while working. However, during repetitive tasks like counting nuts and bolts, they began to consider automation. The author demonstrates their latest creations, which involve laser-cut acrylic sheets assembled with scrap PLA filament. The design features specific hole dimensions that accommodate a press fit, utilizing techniques previously demonstrated in another project. They've also included a pivot made from a
