The author discusses their concerns about Rails' `delegated_type`, a feature that offers a way to implement multi-table inheritance through delegation rather than traditional inheritance. The author has previously found the term “delegated types” unclear and notes their dissatisfaction with its enforced structure. They describe delegated types as an outer "metadata" type that manages shared data and behavior across inner "content" types, which can have unique characteristics. Using an example, the author points out that inner types, such as `Message

The website serves as a nostalgic look back at early web development, using outdated technologies reminiscent of the early 2000s. The author acknowledges the simplicity of websites from that era, which were often created with basic tools like Notepad or primitive WYSIWYG editors that restricted HTML maintainability. Key characteristics of early sites included a lack of mobile optimization, minimal use of CSS and JavaScript, and color schemes designed for low-quality displays. The common screen resolution was around 1024×768,

The author created a proof-of-concept system that allows real-time bidirectional editing between a modern code editor and a GUI, using an LSP server. As a programmer who enjoys working on small projects that involve CAD and has a comfortable development environment, the author was intrigued by Kevin Lynagh’s work on codeCAD, particularly the concept of bidirectional editing. The idea is that changes in the GUI should reflect automatically in the source code and vice versa. However, the author expresses a preference for coding

At the Federal Reserve Bank of Chicago's Money Museum, a transparent cube filled with tightly packed stacks of $1 bills claims to showcase $1,000,000. A visitor, skeptical of the display's accuracy, attempts to count the stacks both in person and via a photo but struggles to keep track. Realizing there is no simple web tool for counting items in images, the visitor creates "Dot Counter," a straightforward app that allows users to click on an image to place dots and keep a tally

Alex, a software resilience engineer based in Washington, DC, has experience in government, private sector, and open-source projects. He focuses on building effective systems and is currently employed at Anthropic. His discussion begins with ASN.1, a meta-serialization format used to describe data abstractly, and its associated encoding, DER (Distinguished Encoding Representation). Alex maintains a Rust library called rust-asn1 for DER parsing and serialization. DER operates on a type-length-value (TLV) binary format

The N+1 query problem arises when an application sends one SQL query for each element in a collection, resulting in unnecessary multiple queries instead of a single efficient one. This issue often stems from a leaky abstraction in the ORM (Object-Relational Mapping) used, which cannot optimize these queries automatically. The typical solution involves moving the abstraction boundary downwards to instruct the ORM to fetch rows in bulk rather than individually. However, the author suggests an alternative approach: raising the abstraction boundary by integrating the

Judoscale focuses on providing rapid and reliable queue-time-based autoscaling, believing that queue time is the most critical metric for real applications. Their goal is to enable instances to scale up quickly, often within 10 seconds of a queue time increase. However, they've acknowledged that queue time may not always be the optimal metric for every situation and have developed an alternative method that can be more effective in certain cases. Queue time measures how long requests wait before being processed by servers, which directly correlates

AI agents are evolving to perform actions beyond basic Retrieval-Augmented Generation (RAG), facilitated by standards like the Model Context Protocol (MCP). This development necessitates fine-grained permissions and access controls, transitioning away from hardcoded user roles to a more dynamic authorization model, such as Policy-Based Access Control or Attribute-Based Access Control. The guide emphasizes the creation of a secure MCP server managed by Cerbos, a policy-driven authorization service, to ensure that AI agent tool access is governed by human-readable

The content discusses the responses to a previous post titled "Mr. Golang's Wild Ride," which has been widely shared across platforms like Reddit and HackerNews. The author reflects on the polarized reactions it generates, focusing on the dismissive criticisms and the more thoughtful comments. They highlight a tendency for experienced developers to overlook issues due to familiarity, while junior developers, with fresh perspectives, question the status quo. This drives the author to advocate for hiring junior developers for their ability to identify problems that seasoned developers

The article emphasizes the importance of HTTP caching for Rails developers, highlighting its potential to significantly reduce API requests—up to 90%—without requiring additional caching code. While many developers focus on fragment caching and related techniques, HTTP caching remains underutilized despite being built into HTTP clients and requiring no extra infrastructure. The writer points out that typical Rails APIs often serve fresh responses for every request, leading to unnecessary database queries and server load, especially with high traffic. This inefficiency arises mainly because Rails applications

The article by Lance Martin discusses the importance of context engineering in the functioning of AI agents, particularly in the realm of large language models (LLMs). Context engineering is described as a critical process that fills the context window of an agent with appropriate information throughout its task progression. Martin draws an analogy to computer systems, where the LLM acts as the central processing unit (CPU) while its limited context window functions like RAM, highlighting the need for careful information curation. As the capabilities of LLMs
