Mobile version of tech blog https://jianghushinian.cn/, covering Golang, Docker, Kubernetes and beyond.
The article details a CI lint failure caused by a corrupted Go module from a GOPROXY mirror, revealing that comma-separated GOPROXY fallbacks only retry on 404/410 errors, while pipe-separated fallbacks retry on any error—a behavior confirmed by Go source code analysis.
The author details how they built the onexai toolkit — 46 convention tools and 20 scaffolding commands — to feed structured, high-quality Go standards to AI via MCP, enabling consistent, production-grade code across projects with 96% similarity to reference implementations like miniblog and onex.
The article explains how Go's vanity URLs work, detailing the three core meta‑tag protocols (?go-get=1, go-import, go-source), the step‑by‑step actions of the go get command with -x logging, and how these mechanisms enable both the Go CLI and pkg.go.dev to locate and document source code.
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.
