Daily sharing of Golang-related technical articles, practical resources, language news, tutorials, real-world projects, and more. Looking forward to growing together. Let's go!
This article walks through constructing a high‑performance server‑monitoring probe in Go, integrating DeepSeek's large language model for AI‑driven anomaly analysis, and demonstrates end‑to‑end setup, metric collection, alert throttling, compilation, and stress‑testing on Ubuntu.
This article demonstrates how to quickly add lightweight, plug‑and‑play monitoring to a Go service using the open‑source go-commons library, showing installation, a minimal 50‑line example that exposes business QPS and system metrics via a single /metrics endpoint, and how to integrate it with Prometheus and Grafana.
This handbook provides a thorough overview of Ceph’s architecture and core principles, followed by detailed step‑by‑step instructions for common cluster operations, fault diagnosis, and advanced configuration, serving both newcomers and experienced administrators seeking to master Ceph storage management.
This guide presents a concise reference of the most frequently used Go commands—including go build, go install, go get, go doc, godoc, go test, go list, and go fix—explaining each command’s purpose, typical usage, and key flags to help developers work efficiently with the Go toolchain.
This article introduces ten widely used Linux operations tools—Shell, Git, Ansible, Prometheus, Grafana, Docker, Kubernetes, Nginx, ELK Stack, and Zabbix—detailing their functions, typical scenarios, advantages, and concrete usage examples to help engineers streamline daily tasks.
The article categorizes Go learners into four groups, presents three detailed roadmap diagrams covering fundamentals, core language features, and ecosystem topics, and explains how anyone—whether a beginner or experienced programmer—can follow these visual guides to systematically study Go over three months.
The article walks through a disciplined Go development workflow—red‑green‑refactor—explaining how test‑driven design, table‑driven tests, minimal viable code, and Go‑specific tooling together produce robust, maintainable code while illustrating each step with concrete examples and code snippets.
This article explains why error handling is crucial in Go, demonstrates the language's explicit error model, walks through basic error representation, return and checking, introduces custom error types, error wrapping, error chains, best‑practice guidelines, and centralised handling patterns with concrete code examples.
This article explains how Go struct pointers work, compares value and pointer passing with concrete code examples, demonstrates memory and speed benefits for large structs, shows how to use pointers in function parameters and interfaces, and provides best‑practice guidelines and a real‑world case study showing up to 70% memory savings and 40% speed gains.
FastCache, an open‑source Go in‑memory cache from the VictoriaMetrics team, delivers extreme speed, zero garbage‑collector pressure, and built‑in thread safety through a shard‑bucket design, while offering a five‑method API that lets developers cache massive key‑value data with minimal configuration, making it ideal for high‑concurrency services and low‑latency workloads.
