Learn Design Patterns: Understanding the Abstract Factory Pattern

The Abstract Factory Pattern is a creational design pattern that provides an interface for creating families of related or dependent objects without specifying their concrete classes.
The pattern helps manage families of related objects without tight coupling and abstracts the object creation process.
It simplifies the addition of new platforms, ensures consistency within a platform family, and decouples object creation from the client code.
Real-life projects that use the Abstract Factory Pattern include cross-platform frameworks, database connection managers, and theming systems.

The compiler must honor the API contract of awakeFromNib, which is a special-case issue.
Some APIs, like Notifications, won't work well with Swift concurrency and may be deprecated and replaced.
TIL: awakeFromNib() can be called more than once when objects are loaded from XIBs.

LLM Function calling A.I. Chatbot from OpenAPI Document

@samchon/openapi is a collection of OpenAPI types for every versions, and converters for them.
In the OpenAPI types, there is an "emended" OpenAPI v3.1 specification, which has removed ambiguous and duplicated expressions for the clarity.
@samchon/openapi also provides LLM (Large Language Model) function calling application composer from the OpenAPI document with many strategies.
Every API operations can be called by LLM function calling, so that you can easily create an LLM function calling A.I. chatbot just with your OpenAPI document.
The LLM function calling means that LLM automatically selects a proper function and fills parameter values from conversation with the user (may by chatting text).
The structured output means that LLM automatically transforms the output conversation into a structured data format like JSON.
The HttpLlm module allows the LLM function calling extremely easily just by delivering the OpenAPI document.
With HttpLlm.execute(), the actual execution can be performed by yourself.
Just by the TypeScript type. You also can compose LLM function calling application schema from TypeScript class or interface type.
At the next article, it is demonstrated how to utilize typia's LLM function calling schema composer, and how to integrate it with the A.I. chatbot application.

Java’s AtomicInteger.incrementAndGet() Method Explained

The incrementAndGet() method is designed for handling integer values in multi-threaded environments without requiring explicit synchronization.
Atomicity is achieved using low-level CPU instructions like compare-and-swap (CAS), which allows changes to be made only if the current value matches the expected value.
Thread safety is a primary reason for using incrementAndGet().
The incrementAndGet() method is widely used in multi-threaded applications where operations on a shared integer variable need to be thread-safe.
One of the most common use cases for incrementAndGet() is maintaining a counter that multiple threads increment simultaneously.
Another common application of incrementAndGet() is monitoring resource usage, such as the number of active connections to a database or active users in a web application.
In logging systems, maintaining an incrementing identifier for log entries can help track their sequence in multi-threaded applications.
While AtomicInteger.incrementAndGet() is designed for thread-safe and atomic operations, understanding potential edge cases and incorporating proper error handling can prevent unexpected issues in specific scenarios.
In applications with very high thread contention, the performance of AtomicInteger.incrementAndGet() may degrade as multiple threads repeatedly attempt to perform the atomic operation.
The AtomicInteger.incrementAndGet() method provides a reliable and efficient way to handle thread-safe integer operations in multi-threaded environments.
