This article explains the simple arithmetic principle behind a New Year magic trick and provides a complete Go program that calculates the hidden number, interacts with the user, and demonstrates the trick with sample input and output.
This guide shows how to use the osbuilder scaffold to quickly generate a complete enterprise‑grade Go project—including a web server, async job server, message‑queue server, and CLI tool—by configuring a YAML file, adding resources, and implementing business logic.
This guide explains three methods for moving Docker images between registries—including simple tag‑and‑push, Buildx multi‑platform builds, and manifest‑based migrations—detailing step‑by‑step commands, required variables, pros and cons, and troubleshooting tips for both single‑arch and cross‑architecture image transfers.
This article introduces AIO Sandbox, an all‑in‑one Docker container that unifies browser, shell, VSCode, and Jupyter environments, provides agent‑oriented APIs and multi‑language SDKs, and demonstrates a quick‑start workflow and a Python example converting web pages to Markdown.
This article introduces the Model Context Protocol (MCP) Go SDK v1.0.0, explains its stable API guarantees, provides quick‑start examples for building MCP servers and clients in Go, and outlines the SDK's modular design and error‑handling strategy for AI‑enabled backend development.
This article introduces the open‑source Go AI Agent framework Blades, showing how to quickly set up a chat with a large model, enable streaming responses, and implement multi‑turn conversations using prompts, memory, and custom middleware, with complete code examples.
This article explains how Go's sync.Pool works, shows practical usage examples, walks through its source code, and details the underlying implementation, including Put/Get methods, pinning, and garbage‑collection interaction, helping developers efficiently reuse objects in concurrent programs.
Go’s built‑in concurrency primitives make parallel programming easy, but testing such code is tricky; this article explains the experimental testing/synctest package introduced in Go 1.24/1.25, shows how to rewrite flaky, slow tests into fast, reliable ones, and demonstrates its use with real‑world examples.
This article explores the origin of the Go programming language’s name, detailing its creation by Rob Pike, Robert Griesemer, and Ken Thompson, the emergence of the “golang” moniker, official naming conventions, and why the correct term remains simply Go.
Go 1.25 introduces a container‑aware default for GOMAXPROCS that automatically aligns the runtime’s parallelism with CPU limits in orchestrated environments, reducing throttling latency, improving efficiency, and making Go applications production‑ready out of the box.
