The author created a real-time rendering Game Boy Color game, where players control a light orbiting around a spinning object. They experimented with the visual effects in Blender to ensure the design was appealing. The project utilizes cryptomattes and custom shaders to enhance normal maps. The author chose Blender for ease, producing normal maps by rendering a teapot in a 3D scene and exporting a PNG sequence. For the Game Boy Color, specific colors were solidified using cryptomattes to identify geometry. The

PostgreSQL is capable of scaling effectively in production, but many setups use conservative default settings that may not be optimal. Performance optimization involves understanding how settings interact and verifying their impact with metrics. This guide focuses on two key memory parameters, starting with **shared_buffers**, a crucial concept in PostgreSQL. **shared_buffers** refers to the size of the shared memory area used as an internal buffer cache. When data is requested, PostgreSQL first loads it into shared memory instead of streaming it directly from the

The content describes an open-source testing tool designed for Model Context Protocol (MCP) servers, which helps detect breaking schema changes before they impact production environments. This tool enables users to validate schemas deterministically and offers optional LLM-powered behavioral exploration, making it compatible with CI/CD processes, including GitHub Actions. MCP is crucial for AI assistants like Claude to interact with external tools via JSON schemas, and changes to these schemas can silently disrupt AI workflows. The tool allows users to simply check for changes without

The content describes jsongrep, a command-line tool and Rust library designed for querying JSON documents using a JSONPath-inspired query language that employs regular path expressions. Unlike imperative tools like jq, jsongrep allows users to declare paths to match in JSON trees, which are structured with objects and arrays. The tool compiles queries into a deterministic finite automaton (DFA) for efficient execution. Users can create complex, nested queries using regular expression syntax, and the tool supports future enhancements for pattern matching
