A Haystack pipeline can be perfectly wired and still unsafe. The retriever returns documents. Every component did its job. But if untrusted text moved through the pipeline as ordinary context, the trust boundary was lost. That is the problem this post is about. Not bad Python. A valid component connection only says: this value fits the next component It does not say: this value is safe to influen

This isn't an anti-Go post. Go is a great language. This is about what I want to understand. I just finished building an L7 HTTP load balancer in Go. It accepts connections. It parses HTTP headers. It forwards requests to backend servers using round-robin. It handles concurrent connections with goroutines. It has health checks. It works.

Most developers use malloc without thinking much about what happens underneath. This project is an attempt to explore that layer by building a memory allocator from scratch in C. The allocator implements malloc, free, calloc, and realloc without relying on libc’s heap functions. It focuses on: Thread safety Per-thread caching (tcache) Efficient free block management using bins mmap-based memory g

Comparison: Haystack 2.0 vs. RAGatouille 0.3 for Building High-Accuracy RAG Pipelines for Developer Docs Retrieval-Augmented Generation (RAG) has become the standard for building LLM-powered tools that answer questions using private or domain-specific data. For developer documentation (dev docs) — which includes technical jargon, versioned APIs, code snippets, and structured reference material —
