Mobile version of tech blog https://jianghushinian.cn/, covering Golang, Docker, Kubernetes and beyond.
The author details both manual and one‑click migration of roughly 500 GB and 760 000 files from an older Intel‑based MacBook Air to a new M‑chip MacBook Pro, covering setup, SSH key handling, transferred settings, and a useful cursor‑speed command.
This article explains Go's error‑handling shortcomings, introduces the popular third‑party pkg/errors library, demonstrates how to wrap errors with additional context and stack traces, and provides a detailed line‑by‑line walkthrough of its source files (errors.go, go113.go, stack.go) to reveal the underlying design and implementation.
This article explains how to implement graceful shutdown for Go programs, covering signal handling with os/signal, closing HTTP servers without interrupting active connections, managing goroutine lifecycles, and providing complete example code for both the standard net/http package and the Gin framework.
This tutorial explains how to install Docker Buildx, create and manage builders, and use QEMU emulation or Go cross‑compilation to produce multi‑platform Docker images, covering command syntax, driver options, global BuildKit variables, and how to push or load the resulting images.
During a production deployment of large language model training on Kubernetes, a pod failed due to insufficient /dev/shm shared memory; the article details the root cause, explores missing pod spec parameters, and presents a complete solution using an emptyDir volume with medium: Memory and sizeLimit to configure shared memory.
This article explains the Adapter design pattern, illustrates its real‑world analogy, demonstrates a complete Go implementation for payment processing, and shows how the pattern can be used in production scenarios such as a multi‑cloud management platform and a model‑training service, highlighting its role in unifying incompatible interfaces.
This article introduces the Chinese copywriting guidelines, explaining why spaces between Chinese and English, numbers, units, and punctuation matter, providing concrete examples and best‑practice rules, and showcasing the autocorrect CLI tool and language libraries that can automatically enforce these formatting standards.
Since Go 1.16, the //go:embed directive allows developers to embed files, directories, or entire static assets directly into the compiled binary, simplifying deployment; this article explains the directive, its three embedding methods, usage in HTTP servers, unit tests, handling parent directories, and important considerations.
This article explains the concept of false sharing caused by CPU cache line interactions, demonstrates how cache padding can mitigate the performance penalty, and provides Go benchmark code and results to illustrate the impact on multi‑core concurrency.
This article demonstrates how to apply Google’s Wire tool in a production‑grade Go web service, covering project layout, a four‑layer architecture, code generation for constructors, comparisons with dig and inject, and practical CLI usage to streamline dependency injection and improve development efficiency.
