완전탐색 강의 마지막 문제 1090번 문제 풀이 방법에 의문이 생겨서 질문 올려봅니다. 강의에서는 우리의 집 중에서 한 곳에 모이면 된다고 풀이를 하셨는데, 예시에 나온 4 15 14 15 16 14 15 16 15 4명이 모이기 위한 최적의 장소는 (15,15)입니다. 백준에서도 이것이 정답 좌표이고. 그래서 혹시 제가 1번 2번 3번 아이디어를 이해하는데에서 잘못 이해한 부분이 있을까 싶어 질문을 올립니다. (15 14) (15 16) (14 15) (16 15) 중에 하나에 모인다는 말이 아닌것인가요?

자바 ORM 표준 JPA 프로그래밍 - 기본편
fetch join 시 alias를 사용해서 필터링하는게 왜 안되는걸까요? 이거에 대한 답변으로 디비상태와 객체상태의 일관성이 깨지게 됨을 보통 얘기하시는것같아요 alias를 사용해서 필터링해버리면 실제 디비에 있는 데이터보다 적은 개수가 나오게 되니까요. 근데 어차피 그 필터링된 결과만을 결과로 리턴해주어야한다면 사용해도 괜찮을 것 같은데 디비상태와 객체상태의 일관성이 깨지는게 왜 문제가될까요? 그래서 생각을 해봤는데 크게 다음인것같아요 - 유지관리어려울 수 있음 - 캐싱문제 근데 저 두 문제가 정말 큰 문제가 되는지를 잘 모르겠어요...; 유지관리 어려울수야 있겠지만 그렇게 까지 어려울지도 잘 모르겠고, 캐싱문제(쿼리결과캐싱)도 저 코드에 의해 영향이 얼마나 많이 갈지..도 잘 모르겠어요 저 유지관리/캐싱 문제가 아니라.. 2차캐시때문인가요? 예를들어서 team과 member가 일대다 연관이고 team을 select해온다는 sql이 있다고 가정 1. fetch join + on 절 : 디비에 있는 일부 데이터 불러옴 2. fetch join 만있어서 디비에있는 모든 데이터 불러옴 하나의 트랜잭션에서 1호출 뒤에 2를 호출하면 디비에 쿼리를 날리긴하지만 이미 team_id에 해당하는 객체가 영속성 컨텍스트에있어서 가져온거버림 그래서 추후에 문제가생길 수 있음 --- 인건가요?

실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발
테스트용 데이터를 추가하기 위해 아래와 같은코드를 만들었습니다. @Component @RequiredArgsConstructor public class TestDataInit { private final ItemService itemService; private final ItemRepository itemRepository; /** * 테스트용 데이터 추가 */ @PostConstruct public void init() { itemService.saveItem(new Book("김영한","츨핀시한빛")); itemService.saveItem(new Book("호날두","출판사멩구")); //오류 발생// itemRepository.save(new Book("a","출판사a")); itemRepository.save(new Book("b","출판사b")); } } 한번은 itemService를 이용하여 값을 넣었고 다른 한번은 itemRepository를 이용하여 값을 넣었습니다. 제 단순한 생각으로는 '어차피 itemService는 itemRepository에 바로 위임을하니 바로 itemRepository로 저장하자' 여서 실행했더니 localhost에서 연결을 거부했습니다. 오류가 나왔습니다. <질문> 왜 itemRepository로 저장하면 안되고 itemService로만 저장해야 데이터가 추가되는 지 궁금합니다.

강의 코드를 그대로 따라가고 있지는 않고 기존에 알고 있던 내용이랑 합쳐서 코드를 작성하고 있습니다. Controller @PutMapping("/user") public void updateUserName(@RequestBody UpdateUserDto updateDto) { userService.updateUserName(updateDto.getId(), updateDto.getName()); } Dto public class UpdateUserDto { private long id; private String name; public long getId() { return id; } public String getName() { return name; } Repository @Override public void updateUserName(long id, String name) { String sql = "update user set name = ? where id = ?"; jdbcTemplate.update(sql, name, id); } Service @Override public void updateUserName(long id, String name) { userRepository.updateUserName(id, name); } 수정을 눌렀을 때 name은 정상적으로 값이 넘어오는데 id가 계속 0으로 넘어옵니다,, 등록 시에는 DB에 id가 정상적으로 입력되고 있는데 뭐가 문제일까요?

우리를 위한 프로그래밍 : 파이썬 중급 (Inflearn Original)
안녕하세요. 강의 감사히 잘 듣고 있는 수강생입니다. 클로저 관련 내용을 듣다 궁금한 점이 있어 질문 드립니다. 해당 문제와 관련하여 다른 분들도 동일한 질문을 여러 번 올려주셨는데 "명확하게 이렇기 때문이다"라는 답변이 없이 외부 링크를 걸어주시거나 단답형으로 답변을 주셨던 것 같아 다시 질문을 드립니다. def closure_ex1(): # Free variable series = [] # 클로저 영역 def averager(v): # series = [] # 주석 해제 후 확인 series.append(v) print('inner >>> {} / {}'.format(series, len(series))) return sum(series) / len(series) return averager avg_closure1 = closure_ex1() # 잘못된 클로저 사용 def closure_ex2(): # Free variable cnt = 0 total = 0 def averager(v): cnt += 1 # cnt = cnt + 1 total += v return total / cnt return averager avg_closure2 = closure_ex2() 위 두 함수 closure_ex1과 closure_ex2를 비교하면 차이는 series는 list, cnt와 total은 int형 변수라는 것, averager 함수 내부에서 series는 append 작업을 하고, cnt와 total은 값을 더해주는 작업을 한다는 것 입니다. 그런데 closure_ex1에서는 오류가 나지 않고, closure_ex2에서는 averager 안에 nonlocal cnt, total을 작성하지 않으면 오류가 납니다. 여쭤보고 싶은 것은, [1] closure_ex1의 averager 함수 내부에 nonlocal series 라는 코드를 작성하지 않아도 되는 이유가 무엇 때문인가 입니다. closure_ex2의 averager 안에 nonlocal cnt, total 이 필요한 것은 내부 함수의 영역은 local 영역이고 closure_ex2 내부이면서 average 외부인 영역은 nonlocal 영역이기 때문에 local 영역에서 free variable을 write 작업하기 위해서는 nonlocal 변수 선언이 필요한 것으로 알고 있습니다. 하지만 series 변수에 대해서는 왜 nonlocal series 라는 코드가 필요하지 않은 것인지요? 제가 추가로 공부할 링크를 주시는 것은 감사하지만, 이 질문에 대한 답변을 명확하게 댓글로 작성해주시면 감사드리겠습니다. 다른 분들의 질문에 올려 주신 링크는 모두 읽어보았습니다. 또한 명확한 답변을 주시면 공부하시는 다른 분들께도 유용할 것이라고 생각합니다. 감사합니다. ps. 강의 영상을 확인하라는 답변도 주셨었는데, 수업에서 정확하게 list나 int형 자료의 scope 별 생명 주기까지 설명한 내용은 찾지 못하였으니 만약 해당 내용이 필요하다면 강의 시간을 알려주시면 감사드리겠습니다.

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 강의 내용을 질문할 경우 몇분 몇초의 내용에 대한 것인지 반드시 기재 부탁드립니다. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. 안녕하세요. 규제 부분 코드 실습 중 규제 클래스에 관해서 cross_val_score적용 시 NaN값이 반환되는 것이 확인되어 질문드립니다. 싸이킷런 버전의 경우 1.0.2버전인데 구글링을 했을 때는, 데이터 내에 NaN값이 있어서 그럴 것이라는데 제가 확인해봤을 때는 NaN값이 없었습니다. 혹시 버전과 관련된 문제일까요...? 동일 코드에 Ridge클래스대신 LinearRegression클래스로 대체시 정상적으로 코드가 동작하는 것을 확인하여 우선 Ridge클래스에 대한 문제로 간주하고 있습니다...ㅠ

이전에 혼자 ddd, 헥사고날 아키텍처를 공부하면서 느꼈던게 객체지향적인 코드 + 테스트하기 용이한 코드를 작성하기 위해서는 결국 domain layer와 persistence layer의 분리가 필수적인데 jpa entity와 domain entity를 완전히 분리했을 때 JPA가 mybatis나 jdbc template를 사용하는 것과 비교해 가지는 강점이 있는지 잘 모르겠습니다.. 그나마 jpa entity와 domain entity를 분리하지 않는다면 어떻게든 온몸 비틀기로 그나마 테스트하기 용이하고 객체지향스러운 코드를 작성해볼 수는 있지만 결국 복잡한 로직에서는 쿼리 때문에 문제가 생기고 ㅜ 지식 공유자님께서는 이 문제에 대해 어떻게 생각하시나요?

클래스의 상속과 관련된 다형성은 부모객체로 인스턴스를 생성하여 부모클래스의 메소드와 자식클래스 메소드 2가지를 업/다운캐스팅하여 자유롭게 호출할 수 있지만, 단일상속이라는 한계 때문에 다른 부모클래스의 메소드는 호출할 수가 없잖아요? 그래서 인터페이스가 존재하는 이유구요. 마찬가지로, 인스턴스를 생성할 때 다형성을 활용하여 인터페이스 객체(부모 객체)로 생성할 수는 있지만, 이것은 ISP(Interface Segregation Principle)원칙에 따라 detect(), report() 2개의 메소드를 호출하려면 Detectable, Reportable 객체 2개를 생성해야 하기 때문에 메모리가 효율적으로 관리되지 못하는거구요. 따라서 구상클래스인 FactoryCam에서 인터페이스 변수를 직접 생성하고 setter함수로 필요한 인터페이스 변수를 주입한 다음(Dependency Injection) , 주입당한 객체는 인터페이스에 의존하기 때문에(Reportable, Detectable) 동시에 기능이 다른 2가지 메소드를 호출할 수 있는거구요.(Dependency Inversion Principle) ... 과정을 이해하였지만 말로 풀어내니까 굉장히 장황하군요 사실 이 부분은 인터페이스 문법이라기보다는 디자인 패턴과 관련이 있지 않나싶습니다.
