Read source code together, write articles together, and enjoy spicy hot pot together.
This guide explores how to harness Claude Code effectively by structuring prompts, using CLAUDE.md, managing context windows, creating reusable skills and commands, handling stuck situations, and even running the model locally with Ollama for a powerful, self‑contained coding assistant.
This article explains what high‑throughput means for an HTTP server, why Node.js’s event‑driven, non‑blocking architecture makes it ideal, and provides step‑by‑step code examples—including a basic server, blocking vs. async I/O, clustering, keep‑alive, JSON optimization, and streaming—to help developers design scalable, low‑latency services.
This article explains what MessagePack is, compares its size and speed to JSON in Node.js with real benchmarks, shows how to use the msgpackr library, and outlines the scenarios where its smaller binary payloads and native binary support outweigh its slower CPU serialization.
This article explains the core differences between git rebase and git merge, illustrates how each rewrites or preserves commit history with concrete command examples, outlines safe usage scenarios, and provides practical tips to prevent code loss during collaborative development.
This guide explains what a Blob is, how to create it with JavaScript, generate and manage temporary Blob URLs, compare it with Base64 and ArrayBuffer, and apply best‑practice patterns for previewing, downloading, and streaming large files in modern web applications.
This article explains how JavaScript's single‑threaded nature can freeze UI during heavy calculations and shows step‑by‑step how to offload work to Web Workers, integrate external libraries, configure build tools, and follow best practices for smooth, responsive web applications.
This guide explains how the new JavaScript Array.fromAsync() method converts async iterables, streams, or paginated API responses into clean arrays, offering clear syntax, practical use‑cases, and step‑by‑step code examples for front‑end developers.
This article showcases eight often‑overlooked TypeScript capabilities—discriminated unions, as const,{ } tuples, template literal types, keyof + typeof, strict mode, noUncheckedIndexedAccess, and type augmentation—each with concrete examples and practical guidance on how they improve type safety and reduce boilerplate.
The article introduces Token‑Oriented Object Notation (TOON), a compact alternative to JSON designed for large language models, and demonstrates how its reduced syntax cuts token usage by up to 60%, speeds up parsing, and remains human‑readable.
This article explains the problem of finding the longest substring without repeating characters, demonstrates a brute‑force O(n³) solution with code, then introduces an optimized sliding‑window approach that runs in linear time O(n), including detailed implementation, complexity analysis, and key insights.
