Summary
Inefficient work practices in organizations create a significant amount of waste that doesn’t benefit the customer. Taylorism, which advocates for a strict work structure, causes cognitive strain and inefficiency in product development organizations.

Fact

🕰️ Taylorism promotes a hierarchical work structure where the Manager, Expert, and Worker roles are very distinct.

🤔 The Expert decides how to do things, minimizing feedback and causing cognitive strain.

💻 In product development and creative work, Taylorism creates inefficient work and cognitive strain.

Summary
Grumpyrest is a Java REST server framework that doesn’t use annotations, automatic dependency injection or reactive streams, and prioritizes the use of Java’s type system to indicate the meaning of classes, fields, and methods. It also avoids typical REST frameworks’ approach on URL, request properties, and response objects.

Fact

🚀 Grumpyrest minimizes the use of reflection and instead relies on Java’s type system for indicating the meaning of classes, fields, and methods.

🏔️ Grumpyrest utilizes virtual threads to achieve parallelism and high I/O.

💻 Something unique about Grumpyrest is to mount an endpoint to a URL, rather than annotating the handler method; you call a mount method and pass the handler as a parameter instead.

🔍 To access request properties, such as URL path parameters or query string parameters, you don’t declare handler parameters; instead, you call a method that takes a specification of the expected type and performs validation before returning its data.

🏮 Grumpyrest relies on Java records for JSON mapping to define valid fields for request and response objects.
