news.ycombinator.com Unknown 2025-12-02 17:24:07

When we started building a durable workflows library, the most critical architectural decision we faced was what data store to use for workflow metadata. The core durable workflow operations are simple–checkpointing workflow state and recovering an interrupted workflow from its latest checkpoint. Almost any data store can handle these operations, but choosing the right one is critical to ensure workflows are scalable and performant.

Laminar Flow Airfoil

news.ycombinator.com Unknown 2026-01-08 08:54:27

Laminar Flow is the smooth, uninterrupted flow of air over the contour of the wings, fuselage, or other parts of an aircraft in flight. Laminar flow is most often found at the front of a streamlined body and is an important factor in flight. If the smooth flow of air is interrupted over a wing section, turbulence is created which results in a loss of lift and a high degree of drag. An airfoil designed for minimum drag and uninterrupted flow of the boundary layer is called a laminar airfoil. The
