OCP에 대해서 궁금한 점이 있습니다. 제가 이해하기로는 OCP란 기능을 확장을 했을 때, 구성 영역인 AppConfig와 확장된 기능에 대한 코드 말고 클라이언트 코드(사용 영역)의 변경이 없어야 된다고 이해했습니다. 그런데 만약에 여기서 기능의 확장을 하면서 메서드 명이 바뀐다거나 메서드의 인자가 추가된다고 했을 때는 결국 OCP를 지킬 수 없다고 생각을 합니다. 다음은 제가 생각한 예시입니다.예시 1 인자추가 또는 변경 => 강의에서 사용하신 discount에서 상품에 분류에 따라 할인률이 바뀐다고 한다면 결국 public int discount(Member member, int price) 해당 메서드에서 상품에 가격뿐만 아니라 상품의 종류를 나타낼 인자 혹은 상품이라는 객체를 만들면서 인자를 변경해야 합니다.예시 2 메서드명의 변경=> MemberRepository의 save라는 메서드명을 regist로 바꾼다고 하면 결국 MemberServiceImpl의 코드도 save에서 regist로 변경해야 합니다.결국 두 예시 모두 변경에 닫혀있지 않게 되는데 그렇다고 해서 OCP가 위반되었다고 볼 수 있는 건가요? 이런 모든 경우를 따진다면 사실 OCP는 지킬 수 없는 원칙이라 생각되는데 막상 친구가 저런 반박을 했을 때 딱히 할 말이 없었습니다. 이런 경우에 위반인지 아닌지와 이유에 대해서도 설명해주시면 감사하겠습니다.

list.append 와 list.extend의 차이는 append는 y_test_pred자체를 리스트에 추가를 하는 것이고, extend는 리스트의 맨 끝쪽에 y_test_pred 원소들을 하나씩 다 넣는것으로 이해를 했는데, 여기서는 append나 extend 둘 다 써도 괜찮은 것인가요? 제가 이해한 바로는 그렇습니다!

안녕하세요 강사님. 별도로 코프링 프로젝트를 진행하던 도중 궁금한 점이 생겨서 질문드립니다!프로젝트를 진행하다 보면 API가 늘어날수록 DTO의 개수도 어마어마하게 많아지는 경우가 많은데, 이 경우 코틀린에서는 어떻게 DTO를 관리하는게 좋을지 고민입니다.코틀린은 자바와 달리 public 클래스를 파일과 1:1로 대응시킬 필요가 없다보니 하나의 파일 마다 각 엔티티별로 연관된 DTO를 모아놓는 사례도 보이더라구요.이런 경우에 기존에는 자바를 쓸때처럼 패키지로 나눠서 DTO를 관리하고 있었는데 1번 그림처럼 하나의 파일에 연관된 DTO를 모아서 관리하는 것과 2번 그림처럼 패키지로 나눠서 DTO를 관리하는 것 중에 어느게 더 좋은 방법일까요?

안녕하세요 언리얼 클라이언트 프로그래머를 지망하고 있는 학생입니다.벡터,행렬,변환 이외에도 게임에서 사용되는 수학들을 학습하고 싶어 해당 강의를 수강하게되었습니다.다름이 아니라 책에 추가된 내용이 복소수,쿼터니언,오일러 공식,스켈레탈 계층구조 등등이지 않습니까?? 물론 이들을 추가적으로 학습한다면 direct X를 보는 시야가 넓어질 것 같긴한데엔진 프로그래머를 할 게 아닌데 너무 깊이 들어가는게 아닌가?? 고민이 됩니다이 강의를 통해 대략적인 게임 세계를 이해했다면 물리 공부를 해서 게임 세계를 표현하는데 좀 더 힘 쓰는 게 맞을지? 아니면 책에 추가된 내용들을 학습해 좀 더 깊이있게 엔진을 바라보는게 맞는지 답변 부탁드리겠습니다.대략적인 사용 이유는 아는 상태입니다오일러 각을 통해 회전을 표현하는데 이 경우엔 짐벌락 현상이 발생할 수 있어 쿼터니언을 사용하고 스키닝 애니메이션에서 본에 가중치를 둬서 메시가 늘어나게 한다던가? 그런것들? 

[ViewBinding 기초] 부분을 듣고 있습니다.Fragment()에서는 binding을 getter를 따로 만들고 사용하셨는데, 이렇게 사용하지 않고그냥 private var binding : FragmentFirstBinding? = null이라고 선언하고 onDestroyView에서binding = null 이라고 선언해주는 것과 강의에서 보여주신 방법과 차이가 무엇인가용?
