오늘은 SOLID의 네 번째 원칙인 인터페이스 분리 원칙(ISP)을 자세히 알아볼게요!1. 인터페이스 분리 원칙이란? 💡핵심: "클라이언트는 자신이 사용하지 않는 메서드에 의존하지 않아야 한다"Bad Case: ISP 위반 사례// ❌ 이렇게 하면 안돼요!interface Worker { void work(); void eat(); void sleep();}// 로봇은 먹지도 자지도 않는데 구현해야 함class Robot implements Worker { @Override public void work() { // 실제 작업 수행 } @Override public void eat() { // 불필요한 구현 throw ne..

오늘은 SOLID 원칙을 하나씩 자세히 살펴보면서, 실제 코드로 어떻게 적용하는지 알아볼게요!1. 단일 책임 원칙 (SRP) 이해하기 💡핵심: "한 클래스는 단 하나의 변경 이유만 가져야 한다"Bad Case: SRP 위반 사례// ❌ 이렇게 하면 안돼요!public class Employee { public void calculatePay() { // 급여 계산 // 복잡한 급여 계산 로직 } public void saveEmployee() { // DB 저장 // DB 저장 로직 } public void generateReport() { // 리포트 생성 // 리포트 생성 로직 }}이게 왜 문제일까요? 🤔급여 ..

오늘은 객체지향(OOP)의 핵심 개념을 쉽고 재미있게 알아볼게요!객체지향이 뭔가요? 🤔레고 블록으로 집을 만든다고 상상해보세요.각 블록은 독립적이면서도 다른 블록과 조합 가능비슷한 블록들은 규격이 같아 재사용 가능블록들이 모여 하나의 완성된 구조물 형성객체지향은 바로 이런 레고 블록처럼 프로그램을 객체들의 모임으로 보는 것입니다!4대 핵심 개념 💎1. 캡슐화 (Encapsulation)public class CoffeeMachine { private int water; // 외부에서 직접 접근 불가 public void addWater(int amount) { if (amount > 0) { this.water += amount; } }}마..

Linear algebra is a branch of mathematics that deals with vectors, matrices, and systems of linear equations, enabling the understanding and manipulation of high-dimensional data.The Big PictureImagine a large room filled with objects like chairs, tables, and boxes. Each object can be described by its position in the room using coordinates. Linear algebra helps us understand how to describe, man..

This will explain optimizing rendering in Vue.js by breaking down complex ideas into simpler, relatable concepts, and use analogies to help understand the technical details.The Big PictureImagine your Vue.js application as a restaurant kitchen. You want to make sure each dish (component) is prepared efficiently without wasting resources or time. Optimizing rendering in Vue.js is like organizing ..

We'll explore what the Internet is by comparing it to a vast, interconnected city, understanding its core components, and breaking down its technical details.The Big PictureImagine the Internet as a gigantic, sprawling city. Each building in this city is like a computer or device connected to the network. Roads and highways represent the connections that allow data to travel from one building to..

The article provides a comprehensive overview of the inner workings of ChatGPT, focusing on its architecture, training, and ethical implications.The article from Wired gives readers an inside look at ChatGPT by OpenAI. Here are the key points:Architecture and Training:Neural Network Structure: ChatGPT is built on large-scale neural networks, specifically the GPT (Generative Pre-trained Transform..

SHA (Secure Hash Algorithm) is a family of cryptographic hash functions designed to securely process data into a fixed-size output that appears random.The Big PictureImagine you have a huge pile of documents and you need a quick way to create a unique "fingerprint" for each document. SHA (Secure Hash Algorithm) creates such fingerprints, called hash values, that uniquely represent your documents..

RSA is a cryptographic algorithm used to securely transmit messages and authenticate digital signatures by leveraging the mathematical properties of prime numbers.The Big PictureImagine you have a locked box (the message) and you want to send it to a friend without anyone else being able to open it. RSA (Rivest-Shamir-Adleman) is like a method where only your friend can have the key to unlock th..
