    It's not the YAML spec's fault, but

    A programmer defends YAML against common criticisms, arguing that many complained-about issues stem from improper usage rather than the specification itself. The author shares experiences with YAML in projects like a Discord bot and Space Station 14, noting that explicit deserialization logic prevents problems like implicit type conversion.

    Show HN: 2049 - a roguelike that fuses 2048 and Minesweeper

    2049 is a roguelike game that combines 2048 tile-sliding mechanics with Minesweeper mine detection. Players navigate an 8-depth dungeon where tiles merge on movement, hidden mines act as obstacles, and reaching the bottom staircase wins the game. The game runs via CLI or browser (using Pyodide) with no dependencies beyond Python.

    Build domain-specific harness and long-horizon agents with OS Python framework

    Cayu is a production-grade Python framework for building domain-specific AI agents with full lifecycle control, including context assembly, tool invocation, durable state management, and human oversight. Extracted from a software factory that deployed thousands of applications using specialized AI agents, Cayu addresses production challenges like process failures, state persistence, and cost attribution that existing agent SDKs overlook.
