A hands-on ranking of the 7 best vector databases for RAG in 2026 - Qdrant, pgvector, Weaviate, Milvus, Pinecone, Chroma and OpenSearch - with honest scaling limits and a 10-minute decision framework.
Retrieval-augmented generation explained without the jargon: what RAG actually does, how it compares to fine-tuning and long context, the six ways it goes wrong and how to tell if yours is working.
The frontier has converged - the gap between the top models is smaller than the gap between a good prompt and a bad one. An honest comparison of the latest AI models, with the decision framework that outlasts the leaderboard.
OpenClaw hit 250,000 GitHub stars in 60 days by making AI assistants persistent and capable. Here is how it actually works, what people use it for, and the security record nobody wants to talk about.
MCP became the standard way AI applications connect to tools - nearly 16,000 public servers and support from every major lab. What it is, how the July 2026 stateless spec changed it, and why tool poisoning should shape how you use it.
There are 22,000+ MCP servers and several of the most recommended ones are quietly archived. Here are 15 worth connecting, ranked by how well maintained they are, plus how to vet one before you install it.
