Day 3

Today, I:

• reviewed a well-written PR using technologies I'd never touched before: SAM, LocalStack, and Playwright with PDF generation
• watched Spec-Driven Development: AI Assisted Coding Explained — spec-driven development vs vibe coding, using specs as contracts for AI agents
• watched Don't Build Agents, Build Skills Instead — Anthropic's talk on skills as organized folders of procedural knowledge that complement MCP servers
• read DDIA Chapter 3: Storage and Retrieval — LSM-trees vs B-trees, OLTP vs OLAP, and column-oriented storage
• watched Designing Data-Intensive Applications: Chapter 3 — very nice explanation of OLTP vs OLAP, row vs column storage, B-trees vs LSM trees with visual diagrams
