냉동코더님은 GSON 이 아닌 Moshi 를 사용하시는 이유가 무엇인지 궁금하네요!

(예)[질문 내용]영상에서 12분 40초 부분에 bulkDelete와 관련된 내용입니다. 저는 일단 예제와는 조금 다르게 진행을 하였는데요. delete 하려는 User entity에는 OneToMany 관계로 되어있는 테이블이 하나 있습니다. 그래서 User entity에 Cascade All을 추가했는데 querydsl에서는 에러가 뜨면서 실행이 안되더라구요.제가알기로는 cascade를 설정해주면 entity가 삭제될 때 관련된 foreign key를 삭제해주는걸로 알고 있는데 아무리 찾아봐도 답이 안보여서 이렇게 질문남깁니다.

안녕하세요!38-4 강의를 수강하고 예제 코드를 확인하는 과정에서 몇 가지 궁금증이 생겨 질문을 드립니다.kernel 함수 내 변수에서 register를 붙이시던데 이렇게 붙였을때 이점이 있을까요?두 번째 for문 같은 경우에 halfsize *= 2 이렇게 표현할 수 있는데 비트연산으로 나타 내시던데 이유를 알 수 있을까요??변수를 선언할때 unsigned 만 작성하시던데 이것도 이유가 있을까요??어찌 보면 굉장히 사소할 수 있는 질문들이지만, 그래도 이유를 알면 배울 수 있는 부분이 많을거 같아 질문 드립니다.

Error: Could not find or load main class jpabook.jpashop.JpashopApplicationCaused by: java.lang.ClassNotFoundException: jpabook.jpashop.JpashopApplication위에 처럼 뜹니다.혼자서 검색도 해보았고 환경변수도 바꿔보았는데 무엇이 문제 인가요? 예전에 학습한다고 해봤을떄는 잘되었는데 지금은 안되네요...지금 파일은 영한님 '강의 소스 코드' 파일 입니다 -> 자바 버전 수정 하니 해결완료됨

안녕하세요.선생님이 작생해 주신 코드를 하나하나 검토를 해봐도 아래와 같이 널 예외가 발생합니다.어떤 문제가 있는걸까요?

s= "[({" def re(): arr=[] for i in s: if i =="[": arr.append("]") elif i == "{": arr.append("}") elif i == "(": arr.append(")") elif not arr or arr.pop() != i: print(arr) return False if not arr: return True else: return False print(re())s= "[({" 이라고 할때 not arr의 위치 질문입니다. 마지막 elif문에 not arr조건은 가지 못하니까(for문이 이미 끝났기 때문에) 마지막 elif문이 아니라 for문이 끝나고 arr이 비어 있는지 확인해야 하는거아닌가요??s= "[({" def re(): arr=[] for i in s: if i =="[": arr.append("]") elif i == "{": arr.append("}") elif i == "(": arr.append(")") elif arr.pop() != i: return False if not arr: return True else: return False print(re())위에 식처럼 해야하는 거 아닌지 궁금합니다.답변주시면 정말 감사하겠습니다.

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]안녕하세요. Projections 강의 15:36 에 실행된 쿼리와 제 로컬에서 실행된 쿼리가 달라 질문드립니다.중첩구조의 경우 Team 에 대한 정보는 전체 다 퍼올리는 것으로 강의가 진행되고 있는데, 실행된 쿼리는 Dto 에 맞게 퍼올리는 것으로 보입니다.혹시 해당 내용에 대한 수정사항 알 수 있을까요? 공식문서를 읽는 게 아직 익숙치 않습니다 ㅠ공식 문서에도 해당 내용에 대한 언급이 딱히 없는 것 같아서 질문드립니다!

안녕하세요. 매 회차마다 선생님 코딩 실력에 감탄하며 강의 듣고 있습니다. 지금 페이지네이션 API 만들고 썬더 클라이언트에서도 문제 없이 작동했는데 view 부분에서 setMessageList((prev) => [...prev, ...data.content]);로 바꾸고 나서 처음 화면이 로드되면 API 호출이 두번 되면서 messageList에 데이터가 두번 저장됩니다. 그 이후 더보기 버튼 클릭시에는 size만큼 잘 불러오는데 처음 페이지 로딩때만 두번 나오는 이유를 모르겠습니다. useEffect 부분도 useEffect(() => { if (userInfo === null) return; fetchMessageList(userInfo.uid); }, [userInfo, messageListFetchtrigger, page]); 로 선생님 작성한 코드와 같은 것 같은데 틀린부분 있을까요?React Hook useEffect has a missing dependency: 'fetchMessageList'. Either include it or remove the dependency array.이런 eslint 경고도 나옵니다.강의 계속 돌려보다가 도저히 모르겠어서 질문 남깁니다 ㅠ    - 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.

안녕하세요이전까지는 무리없이 실습 잘 실행하고 있습니다.제가 현 강의로 도커를 처음 접해봐서 지금 하는 질문이 너무 초보적일지도 모르겠네요 ㅠㅠ 섹션3의 실습6을 진행중인데요,현재 도커에jenkins-server, ansible-server, docker-server 가 아래와 같이 돌아가고 있구요도커서버에 접속하여ssh root@localhost -p 10022내부에서 docker ps -a 를 하면강사님처럼 컨테이너와 이미지가 하나도 안떠있는 깨끗한 상태가 아닌위와 같이 세개의 서버가 돌아가고 있다고 나옵니다 ㅠㅠ그렇다고 해당 도커서버에서 stop 을 하거나 rm을 진행하면 아예 10022 도 없어져 버리고..제가 무얼 잘못이해하고 있을까요? 

안녕하세요. 초보자이며 프로젝트 규모가 작다면 어드레서블을 굳이 사용할 필요가 없다는 말씀 듣고 질문드립니다. 기존의 Resource에서 로드하는 방식이 코드도 간결하고 쉬웠는데 어드레서블은 조금 복잡하네요 ㅠㅠ제가 이해한 바로는초기 빌드 용량이 커지거나 로딩 시간이 길어질때씬 이동이 자주 일어나거나 해서 불필요한 메모리를 계속 들고있을 필요가 없을때추후 빌드없이 패치를 구현하고 싶을때등등에서 어드레서블 사용이 권장되는 것 같은데 제가 만드려는 게임에서 어드레서블이 필수인지 판단이 어렵네요.그래서 혹시 강사님께서는 프로젝트에서 어드레서블을 사용하는 것이 효율적일것 같다 라고 판단하시는 어떤 기준이 있으신가 해서 질문드립니다. 항상 좋은 강의 감사드립니다!

 강의 잘 듣고있습니다!강의듣고 개인블로그에 정리하고 있는데 공개로 업로드해도 될까요? 수익창출은 하지않고있습니다!
