Things I learned during the week ending December 27, 2025.
how uv got so fast. UV performance is because of design decisions while rust contributes to micro optimizations.
“LangGraph is an orchestration framework for building stateful multi-agent applications using LLMs. It provides low-level primitives such as nodes and edges, along with built-in features that give developers granular control over agent workflows, memory management and state persistence. This means developers can start with a simple pre-built graph and scale to complex, evolving agent architectures. With support for streaming, advanced context management and resilience patterns like model fallbacks and tool error handling, LangGraph enables you to build robust, production-grade agentic applications. Its graph-based approach ensures predictable, customizable workflows and simplifies debugging and scaling.”
npx -y npm-check-updates tells you the latest versions of your package.json, ignoring pinned versions.
