질문중에 찾아 보니 깃허브에서 자료를 다운받고 ch1 부터 하면 된다고 하시던데 ch1,2 안에 코드가 이미 완성되어 있던데 이러면 그냥 nodebird > prepare 폴더를 만들어서 처음부터 따라 하면 되는걸까여?아님 그냥 깃허브에 있는 자료를 다운받아서 다 지우고 따라하는게 좋을까여?

노드강의 있으신데 익스프레스 강의는 별도로 없고노드강의에서 익스프레스 학습을 추가 해놓으셨는데요.네스트 강의는 별도로 만드셨다 말이죠.네스트와 익스프레스의 차이가 뭔가요?익스프레스는 단순 require('express') 하고 쓰면, 익스프레스 프레임워크를 사용하는 건가요?

타입스크립트는 정적타입이잔아요.노드는 동적타입 언어인가요?순전히 궁금해서 여쭤봅니다.

학원에서 이클립스로 공부를 했는데,요즘 현업에서는 인텔리제이를 쓴다고해서 집에서 환경을 인텔리제이로 바꿔서 하고 싶네요어떻게 설정해야 할지 막막하고,커뮤니티 버전으로 사용해서 기능들 사용하는데 지장없는지도 궁금합니다. ㅎㅎ

구글맵 만들기에서 써클을 하나만 만들었는데여러개의 써클 또는 마커를 만들수있는지 생각해보았는데요..아래와 같이 변수를 계속 만들어서 서클을 만들어 보았는데요, 확장해서 수천개의 서클을 만들려면 수천개의 변수를 만드는 것 말고 다른 방법이 없는건가요??static final Circle circle = Circle( circleId: CircleId('mycircle'), center: companyLatLng, fillColor: Colors.blue.withOpacity(0.3), strokeColor: Colors.red, strokeWidth: 5, radius: 20.0, ); static final Circle circletwo = Circle( circleId: CircleId('mycircle2'), center: LatLng(37.205796, 127.108446), fillColor: Colors.blue.withOpacity(0.3), strokeColor: Colors.red, strokeWidth: 5, radius: 20.0, ); _GoogleMap( initialPosition: initialPosition, circle: circle, circletwo : circletwo, ),class _GoogleMap extends StatelessWidget { final CameraPosition initialPosition; final Circle circle; final Circle circletwo; const _GoogleMap( {required this.circletwo, required this.circle, required this.initialPosition, Key? key}) : super(key: key); @override Widget build(BuildContext context) { return Expanded( flex: 2, child: GoogleMap( mapType: MapType.normal, initialCameraPosition: initialPosition, myLocationEnabled: true, myLocationButtonEnabled: true, circles: Set.from([circle,circletwo]), ), ); } }

최대한 찾아봤는데 6월에 올리신 댓글에 하반기 개설 예정으로 적으셨더라고요. 혹시 언제쯤 개설 예정인지 궁금합니다.  

  404 에러가 나와요이전 강의에서 작성했던페이지들은 잘 들어가지는데유독 지금 만든 jsp는 경로를 못찾는지 안되네요   안녕하세요제가 web폴더안에 servletmvc를 안뒀던 게 문제가 됐던거 같은데맞나요? 그렇다면 왜 그런지 궁금합니다. 주소로 매핑되서 들어가는데 web폴더 안이 아니여서 안된건지... 설명 부탁드립니다.

안녕하세요 강사님 강의 잘 듣고 있습니다.강의를 듣다가 궁금한 점이 있는데요,SQL이 오라클 내부에서 상세실행계획으로 변경된다고하셨는데, 혹시 이와 관련한 괜찮은 책이 뭐가 있는지여쭤봐도 될까요?SQL이 들어갔을때 내부 메커니즘이 궁금합니다.감사합니다.

디버깅 실습을 위해 똑같이 따라했지만 ㅠ UE_LOG에 빨간색 밑줄이 쳐지고 컴파일에 실패했습니다.. 어떻게 하면 문제를 해결할 수 있을지 여쭤보고 싶습니다..!

이부분 초기화 하는 이유가 있을까요?

떴습니다. 현재 파일들은 아래와 같습니다.build.gradleapplication.propertiesMemberServiceJpaMemberRepositoryMemberSpringConfig제가 수업내용중에 어떤걸 놓쳤을까요 ㅜㅜ답변 부탁드립니다. 감사합니다.

페치 조인을 사용하는 메서드의 네이밍 컨벤션을 어떻게 가져가시는지 궁금합니다.예를 들어 Member 조회 시 Team을 페치 조인으로 가져오는 경우 메서드명을 어떻게 정하시나요?public interface MemberRepository extends JpaRepository<Member, Long> { @EntityGraph("team") Optional<Member> findByUsername(String username); }제 경우 페치 조인을 의미하는 접미사( ~Fetch() )를 붙이고 페치 조인하는 엔티티는 해당 메서드에 문서화하는 방식으로 진행 중이긴 한데, 영한님이나 서포터즈 분들은 '이 쿼리 메서드는 페치 조인을 수행한다'를 어떤 방법으로 표현하시는지 궁금합니다.

활성화하면 인터랙션 중인 대상이 유효해지지 않아도 인터랙션을 유지할 수 있다고 하셨는데 이게 무슨 말인지 잘 모르겠습니다.유효하지 않은 대상과 인터랙션을 할 수가 있나요?그리고 예시로 보통 텔레포테이션을 할 때 더이상 Ray Interactor가 Teleportation Anchor나 Area를 가리키지 않는 경우 인터랙션 되지 않도록 할 때 사용한다고 하셨는데 이 부분도 무슨 말인지 잘 모르겠습니다.

안녕하세요~! 강좌에서 .h에는 Mesh라고 적고, .cpp에서는 MESH라고 적는 걸로 익혔습니다. 궁금해서 .cpp의 MESH를 MESHesgone으로 바꿔보았는데 에디터에서 해당 컴포넌트가 적용되지 않은 것으로 보였습니다. 제가 전공이 전혀 무관한 사람이라 너무 기본적인 의문을 가지는 것 같은데 왜 그런 것인지 알려주신다면 저에게 도움이 많이 될 것 같습니다. 감사합니다.

Ing 컴포넌트의 네비게이션 타입을 강좌에 나온대로 진행하였더니 타입에러가 발생해서 문의글 남깁니다.컴포넌트 하단부 도착 마커의 navigation.push("Complete", {}); 에서 push 관련된 타입에러가 발생하였습니다.Property 'push' does not exist on type 'NavigationProp라는 에러메세지가 발생하였는데요.우선 아래의 사진과 같이 navigation의 타입을 재선언 해주면서 해결이 되었습니다.LoggedInParamList 대신에 생성한 IngScreenPorps를 넣어봤으면 push에 대한 에러는 해결되지만 complete라는 네비게이션을 찾지 못한다는 에러가 발생하여 위와같이 해결했는데 옳바른 해결책인지 궁금해서 문의 드립니다! 그리고 추가로console.dir 을 활용하려고 하면TS2339: Property 'dir' does not exist on type 'Console'.위와 같은 에러가 발생하는데 이건 해결책이 없을까요? 혼자 찾아보려고 했으나 찾지를 못하여 문의드립니다.

The .NET Core SDK cannot be located: A valid dotnet installation could not be found. .NET Core debugging will not be enabled. Make sure the .NET Core SDK is installed and is on the path.라는 경고창이 뜨며 디버깅에 문제가 있다고 합니다.실제로 코드창에 에러를 적어도 디버깅 하고난 후에 에러는 경고 되지만 작성 중에는 컴파일러가 찾지 못합니다.

안녕하세요! 좋은 강의 너무 감사드립니다! 한가지 질문 드릴께 있습니다.  OAuth2 로그인 구현 - Authorization Code 요청하기26:25분내용을 보면 첫번째 인증 단계! (response type = code)OAuth2AuthorizationRequest 객체 담아서인가 서버 (keyclack 서버) 에 전달 하게 되는데요이것과 동시에  OAuth2AuthorizationRequest 객체를 sesstion 에 저장을 하게 됩니다. 그러면 사용자는 인가 서버 (keyclack 서버) 로그인을 성공적으로 해결된다면 미리 지정된 redirect url 통해Authorization Code 값을 전달해주는데요!그런 후 미리 OAuth2AuthorizationRequest 객체를 sesstion 저장된것을 가져오는데 만약 해당 서버가 1개 라서 다행이지만scale out 경우 그러니깐 서버가 2대 이상이라면 맨처음 OAuth2AuthorizationRequest 객체 저장할때가 1번 서버라면 OAuth2AuthorizationRequest 객체를 가져올때가 2번 서버라면 이때 각각 다른 서버이기 때문에 가져오지 못하는 문제가 발생되지 않나요? 이때는 어떻게 해결해야 할까요??.. OAuth2AuthorizationRequest 객체를 외부 세션 서버로 저장 할수 있도록 다시 로직을 재구현 해야 하는걸까요?
