The text discusses a recent refactoring of complex code related to customer and order management in an enterprise resource planning (ERP) system. The code refactoring aimed to simplify requests management by leveraging static analysis through applicative functors. These functors allow for a completely static control flow but have limitations in expressing computations that depend on previous results. The goal was to batch queries efficiently without dealing with data dependencies, enabling library users to benefit from batch query APIs without managing batching details. The article also introduces the “

The author revisits their 4 kilowatt solar fence installation to share insights on its design and construction. They highlight the challenges in sourcing materials for small solar setups, as manufacturers primarily cater to utility-scale needs. Using their experience with Ironridge roof mounting systems, they adapted it for vertical mounting, combining Ironridge components with common hardware store items. The project aimed to equalize the costs of mounting solar panels and the panels themselves, achieving nearly equal costs: $100 per panel and $110 per panel
