The article explains how to automate bulk installation of Zabbix Agents using a custom Zabbix module that imports host lists via CSV, adds hosts, installs agents remotely, and displays logs, providing step‑by‑step instructions and screenshots while highlighting typical deployment scenarios.
This article details the architecture, security mechanisms, and implementation of a unified Arthas online diagnosis platform that enables SSH‑free, audited access to Java applications across dozens of isolated Kubernetes clusters, covering control‑plane design, WebSocket tunneling, credential management, RBAC, and front‑end integration with Vue and xterm.js.
The author walks through integrating Agnes AI's free text, image, and video models with Claude Code via CC Switch, details each setup step, runs real‑world tasks such as codebase analysis, webpage generation, diagram creation, and short‑video production, and evaluates the models' capabilities and limitations.
A high‑severity Linux kernel flaw (CVE‑2026‑31431, dubbed "Copy Fail") allows ordinary users to gain root privileges and escape containers via an AF_ALG and splice() optimization bug, affecting major distributions; the article details the vulnerability, exploitation steps, PoC, and mitigation guidance.
The article examines the rapid popularity of the open‑source AI agent OpenClaw, revealing how hype, cost misconceptions, and inadequate security practices create serious operational risks for both individual and enterprise users, and offers concrete SRE‑style safeguards to mitigate these dangers.
This guide explains why a single AI bot becomes inefficient, introduces OpenClaw’s multi‑agent architecture, and provides a step‑by‑step tutorial—including CLI commands, configuration files, and JSON bindings—to set up isolated agents in different Feishu groups that can collaborate through internal communication channels.
When Kubernetes announced the retirement of Ingress NGINX, the author used the OpenClaw AI tool and Higress to analyze, test, and fully automate the migration of over 60 Ingress resources, generating plugins, building WASM modules, and producing a verified operation manual in less than two minutes.
This step‑by‑step guide shows how to set up the open‑source OpenClaw AI assistant on personal computers, cloud servers, NAS or Raspberry Pi, covering hardware requirements, system dependencies, installation scripts, platform integration, advanced skill configuration, and ongoing maintenance.
