This post dives into the internals of scheduling and concurrency, showing readers how to handle millions of clients concurrently with just a single thread. It begins by exploring the challenges of creating a server that can handle multiple clients concurrently using threads, going over concepts like stack allocation, performance, and resource management. It then introduces the concept of async I/O, demonstrating how non-blocking sockets can be utilized to achieve concurrency without threads. Code examples are provided to demonstrate the points made.

This author shares the lessons he learned from working on an LLM-based pair programmer called GPT Pilot. It is important to have a clear initial project description, detailed logging, modular code, and focused prompts. AI-driven coding is iterative in nature. The AI copilot was useful when making decisions.
LUTs are simple data tables that remap colors or values. They offer a powerful and efficient way to manipulate how images and videos are displayed. For example, in video games, they can be used to efficiently add color variations to objects in a scene. LUTs can also be used to optimize performance by precalculating expensive operations.
