Behavioral Supply Chain Security in 2026: Catching Malicious Packages Before They RunCVE scanners tell you about yesterday's known bugs; they say nothing about the malicious package published an hour ago. A guide to behavioral supply chain security in 2026 — how tools like Socket, Syft, Grype, and Sigstore fit together to defend the open-source dependency tree.Production RAG in 2026: Hybrid Search, Reranking, and GraphRAGThe naive embed-and-retrieve RAG of 2023 quietly failed in production. This guide covers the architecture that actually ships in 2026 — hybrid search, cross-encoder reranking, GraphRAG, and the evaluation discipline that holds it all together.AI-Powered Offensive Security in 2026: The MCP Tool-Server BoomIn eighteen months the offensive-security world went from a handful of AI experiments to seventy-plus tools, and the Model Context Protocol is the connective tissue. A look at how MCP tool-servers like pentest-ai and HexStrike are reshaping pentesting — and what defenders should take from it.Reinforcement Fine-Tuning for Agents in 2026: GRPO with ART, verl, and OpenRLHFSupervised fine-tuning teaches an agent what good answers look like; reinforcement learning teaches it to get good outcomes. A practical guide to training multi-step LLM agents with GRPO using ART, verl, and OpenRLHF — architectures, reward design, and when to use each.Visual AI Agent Builders in 2026: Langflow vs Dify vs n8nCode-first agent frameworks get the headlines, but visual builders are how most teams actually ship LLM apps in 2026. A deep comparison of Langflow, Dify, and n8n — architecture, RAG, agents, deployment, and when to reach for each.Agentic RAG Architecture Patterns: Building Autonomous Retrieval SystemsExplore the evolution from naive RAG to agentic RAG architectures.
