Guides for setting up and managing Erlang/Elixir environments:

• vfox: Using the vfox version manager to install and switch between multiple versions of Erlang and Elixir on both Linux/macOS and Windows.
• GitHub Codespaces: Accelerating Elixir development by configuring the environment within GitHub Codespaces.

The blog provides practical guides and deep dives into AI-driven development and automation, including:

• vLLM Inference Engine: Source-level analysis of scheduling loops, PagedAttention, KV Cache, and GPU execution.
• iFlow CLI Action: Using iFlow with Qwen3-Coder and Kimi K2 in GitHub Actions to improve DevOps productivity and generate Slidev-style documentation sites.
• Claude Code: Migration of Hexo blog themes (Volantis to Stellar) and using custom Sub Agents for technical writing (e.g., automatic banner generation).
• n8n Automation: Building RSS feed subscription management and AI summary workflows using n8n and Feishu Multidimensional Tables.
• LLM Integration: Using Sider (ChatGPT Sidebar) with Tongyi Qwen and validating Jenkinsfiles using LLMs via LangChain and Cloudflare Workers AI.

Technical documentation and tutorials for distributed infrastructure:

• Kubernetes: Step-by-step guide to building a public network k8s cluster (single control plane) using Kubeadm.
• etcd Performance: Benchmarking etcd using the go-ycsb tool.
• Chaos Testing: Methodology for chaos/fault testing in etcd and MongoDB using failpoints.

Practical tools and frameworks for software engineering:

• Dotfiles Management: Using chezmoi and VS Code for cross-device configuration synchronization.
• Browser Extension Development: Getting started with the WXT framework for building modern web extensions.
• AI Search Hub: The 'Your New Tab' open-source extension that aggregates multiple AI search engines into a single search box.

Deep dives into low-level systems and security:

• WebAssembly: Analysis of Emscripten's compilation process for converting POSIX C/C++ to browser-executable code.
• Code Coverage: Analysis of cluacov branch coverage, comparing line-level approximation vs. instruction-level precision in Lua bytecode.
• Memory Sanitizers: Comprehensive overview of memory safety detection tools including ASan, TSan, MSan, HWASan, UBSan, and ARM MTE.
