Add Step‑Level Diagnostics to PyTorch Training in Three Lines with TraceML

TraceML provides a lightweight, step‑level profiler for PyTorch training that requires only a few code changes—initializing the library and wrapping each training step—to generate real‑time diagnostics and a compact JSON summary, helping engineers quickly identify whether data loading, forward, backward, or optimizer phases dominate execution time.

Agent = Model + Harness: How the Model Sets the Ceiling and the Harness Sets the Floor

The article explains that AI coding agents consist of a stateless model plus a Harness that provides context, tools, orchestration, hooks, permissions, memory, and session management, and argues that the Harness determines the lower bound of performance while the model defines the upper bound.

How HyDE Transforms RAG Retrieval from Keyword Matching to Intent Understanding

The article explains how Hypothetical Document Embeddings (HyDE) improve Retrieval‑Augmented Generation by generating a synthetic answer before vector search, allowing the system to embed richer semantic intent rather than relying on shallow keyword similarity, and provides a step‑by‑step implementation using LangChain.
