Difference between Spike??, Enabler??, and POC????
A spike, an enabler, and a POC are different activities used in agile software development to explore, validate, or demonstrate various aspects of a product or a system. Here is a summary of each term:
A spike ?? is a time-boxed technical investigation that is done to gain the knowledge necessary to estimate, design, or implement a feature or a requirement. A spike does not produce any working code or product, but rather a piece of information or a recommendation that can be used for further planning or decision-making.
An enabler ?? is a general term for any work that supports the development of the product or the system, such as exploration, architecture, infrastructure, research, design, and prototyping. An enabler can produce a working code or product, but its main purpose is to enable or facilitate the delivery of other features or requirements. An enabler can also reduce the risk or uncertainty of a technical approach or a solution.
A POC ???? (Proof of Concept) is a set of work efforts that aim to demonstrate or validate the feasibility, functionality, or performance of a system or a solution. A POC produces a working code or product, which is usually not refined or optimized for production. A POC can be used to test the viability of the cost-efficiency of an idea, a design, or an approach before investing more resources or effort into it.

?? POLL: Do you use Spring RestClient interface?
Spring RestClient is a synchronous HTTP client introduced in Spring Framework 6.1 M2 that supersedes RestTemplate.
Owen said:
May have to try it out
It features a fluent API that allows method chaining and improves readability.
It also handles request and response bodies as reactive streams.
Spring RestClient is designed for applications built with the Spring Boot framework and integrates well with other Spring components
RestClient restClient = RestClient.create();
String result = restClient.get()
.uri("https://example.com")
.retrieve()
.body(String.class);
System.out.println(result);

?? DESIGN PATTERN: the Quiz!
The _____ Pattern is a design pattern that allows an object to change its behavior when its internal state changes.
It involves a context that delegates its behavior to state objects, making it appear as if the object changes its class.

The State Pattern is a behavioral design pattern in software development that allows an object to alter its behavior when its internal state changes.
It enables an object to appear as if it's changing its class when, in reality, it's changing its behavior based on its current state.
Key components of the State Pattern:
Context: The Context is the object that holds a reference to the current state object and delegates its behavior to the state object.
The context's behavior changes as its internal state changes.
State: The State is an interface or abstract class that defines a set of methods representing the various behaviors associated with different states.
Concrete state classes implement these methods.
Concrete State: Concrete State classes are specific implementations of the State interface.
Each concrete state class defines the behavior that the context should exhibit when it's in that particular state.
The State Pattern is useful in situations where an object's behavior depends on its internal state, and it simplifies code by encapsulating each state's behavior into separate classes.
It promotes modularity, extensibility, and flexibility, making it easier to add or modify states and their associated behaviors.

Captain America says:
I am a programmer
One of the other guys in the elevator asks:
Which programming language do you use?
And Captain America answers him full of self-insurance:
chatGPT!
All the other guys in the elevator beat him after such a saying.
