While these modes are powerful, their effectiveness depends on the quality of the context they can access. https://devopstales.github.io/kubernetes/kubevpn-cloud-native-development/ Sun, 29 Mar 2026 00:00:00 +0000 https://devopstales.github.io/kubernetes/kubevpn-cloud-native-development/ Developing applications for Kubernetes often means constantly deploying code to remote clusters or mocking services locally. KubeVPN bridges this gap by connecting your local machine directly to your Kubernetes cluster network, enabling true cloud-native development without the deployment overhead. https://devopstales.github.io/ai/kilo-code-series-04-modes/ Sat, 28 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/kilo-code-series-04-modes/ In our previous post, we unlocked massive power by integrating Qwen Code CLI. But with great power comes the need for great management. https://devopstales.github.io/ai/kilo-code-series-03-qwen-integration/ Fri, 27 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/kilo-code-series-03-qwen-integration/ In our previous posts, we covered the basics of Kilo Code and how to get it installed on your machine. One of the most powerful features of Kilo Code is its ability to integrate with various AI providers. https://devopstales.github.io/devops/nginx-to-angie/ Fri, 27 Mar 2026 00:00:00 +0000 https://devopstales.github.io/devops/nginx-to-angie/ If you’ve been working with web servers and reverse proxies for the past decade, chances are you’ve used nginx. It’s been the backbone of countless web infrastructures, powering everything from small personal blogs to some of the busiest websites on the planet. But recent developments in the nginx ecosystem have led to an interesting fork called Angie — and it might be worth your attention. In this post, I’ll walk through the history of nginx, what happened after the F5 acquisition, why Angie was created, and why you might want to consider making the switch. https://devopstales.github.io/ai/kilo-code-series-02-install/ Thu, 26 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/kilo-code-series-02-install/ In our first post, we introduced the core concepts of Kilo Code and why it’s a game-changer for agentic software development. Now, it’s time to get your hands dirty. https://devopstales.github.io/ai/kilo-code-series-01-intro/ Wed, 25 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/kilo-code-series-01-intro/ The world of AI coding is moving fast. We’ve seen the rise of simple autocomplete, then the transition to chat-based assistants, and now we are entering the era of Agentic AI. https://devopstales.github.io/virtualization/proxmox-datacenter-manager/ Wed, 25 Mar 2026 00:00:00 +0000 https://devopstales.github.io/virtualization/proxmox-datacenter-manager/ Proxmox Datacenter Manager (PDM) is a centralized management platform for overseeing multiple Proxmox VE clusters and Proxmox Backup Server instances from a single interface. This guide covers installation, configuration, and best practices for managing your virtualization infrastructure at scale. https://devopstales.github.io/ai/vscode-ai-coding-plugins-comparison/ Tue, 24 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/vscode-ai-coding-plugins-comparison/ AI-powered coding assistants have become essential tools for modern developers. In this post, I’ll compare three popular VSCode extensions: GitHub Copilot, Continue.dev, and Kilo Code (kilo.io), helping you choose the right one for your workflow. https://devopstales.github.io/ai/ai-ide-core-concepts/ Sun, 22 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/ai-ide-core-concepts/ Modern AI-powered IDEs have evolved far beyond simple code completion. Today’s tools like Kilo Code, Cursor, Windsurf, and Google Antigravity introduce new paradigms: autonomous agents, reusable skills, markdown rules, semantic context, and structured workflows. https://devopstales.github.io/ai/ai-software-development-spec-vs-vibe/ Sun, 22 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/ai-software-development-spec-vs-vibe/ The early days of AI coding were characterized by “vibe coding”—a process where developers would prompt an LLM, hope for a working snippet, and manually fix the hallucinations. While fast for simple tasks, this approach often falls apart in complex, multi-file projects where “context rot” and technical debt accumulate rapidly. https://devopstales.github.io/kubernetes/multus/ Sun, 22 Mar 2026 00:00:00 +0000 https://devopstales.github.io/kubernetes/multus/ Multus CNI enables attaching multiple network interfaces to Kubernetes pods, essential for service mesh, security isolation, and high-performance networking. This updated guide for 2026 covers Multus 4.0+, Kubernetes 1.28+, and modern CNI plugins. https://devopstales.github.io/ai/ai-ide-configuration-standards/ Sat, 21 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/ai-ide-configuration-standards/ As AI tools become more integrated into our development workflows, the way we configure our projects is changing. We’ve moved beyond simple .gitignore and .env files into a world where we need to provide specific “instructions” and “context” to our AI assistants. https://devopstales.github.io/ai/ai-coding-agents-workflows/ Fri, 20 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/ai-coding-agents-workflows/ Over the past year, I’ve been working extensively with AI coding agents — intelligent assistants that go far beyond code autocompletion. These agents can plan, execute, and iterate on entire development tasks. They function like tireless pair programmers who never lose focus or context, dramatically increasing productivity when guided correctly. https://devopstales.github.io/ai/ai-coding-ides-comparison/ Thu, 19 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/ai-coding-ides-comparison/ The landscape of software development has shifted from “writing code with AI assistance” to “developing in AI-native environments.” While VS Code with GitHub Copilot remains the industry standard, a new breed of IDEs is challenging its dominance by integrating LLMs and autonomous agents into the very core of the editor. https://devopstales.github.io/kubernetes/backup-and-retore-prometheus/ Wed, 18 Mar 2026 00:00:00 +0000 https://devopstales.github.io/kubernetes/backup-and-retore-prometheus/ Backing up Prometheus is critical for preserving your monitoring history and metrics data. This updated guide for 2026 covers modern backup strategies using the Prometheus Admin API, Velero, and volume snapshots in Kubernetes environments with prometheus-operator. https://devopstales.github.io/ai/ai-coding-cli-comparison/ Wed, 18 Mar 2026 00:00:00 +0000 https://devopstales.github.io/ai/ai-coding-cli-comparison/ While AI-native IDEs like Cursor and Windsurf have taken the developer world by storm, a parallel revolution has been happening in the terminal. AI Coding CLIs (Command Line Interfaces) offer a different paradigm: they are lightweight, terminal-native, and often more “agentic” than their GUI counterparts. https://devopstales.github.io/linux/wazuh-pfsense-syslog/ Sun, 15 Mar 2026 00:00:00 +0000 https://devopstales.github.io/linux/wazuh-pfsense-syslog/ Centralizing pfSense firewall logs in Wazuh SIEM provides critical security visibility and threat detection capabilities.
