Explore the drawbacks of using singletons in software development through this comprehensive video tutorial. Delve into the concept of singletons and their context, examining lazy loading and the reasons why singletons are often considered problematic. Compare singletons to global variables and review Meyers' Singleton implementation. Learn techniques to improve singleton design, including making shutdown explicit, avoiding static storage for instances, and removing lazy loading for explicit initialization. Discover the presenter's solution to the "global" situation and gain insights into alternative approaches for managing shared resources in your code.
