fireBase인증 과정에 대하여 질문있습니다. 제가 이해한 것이 맞는지 확인해주시면 감사하겠습니다.질문 1.(1) try { const signInResult = await signInWithPopup(FirebaseAuthClient.getInstance().Auth, provider); if (signInResult.user) { const idToken = await signInResult.user.getIdToken(); const { uid, displayName, photoURL, email } = signInResult.user; // uid // photoURL // displayName const resp = await memberAddForClient({ data: { uid, displayName: displayName || undefined, email: email!, screenName: email!.split('@')[0], photoURL: photoURL || undefined, provider: 'google', }, token: idToken, }); }signInWithPopup메서드를 통해 구글 로그인 후 로그인 한 유저 정보(signInResult)를 가져옵니다.(2) const idToken = await signInResult.user.getIdToken();여기서 accesstoken과 다른 유저정보 email,uid등등을 가져와서 filestore에 저장합니다(3)export default async function verifyFirebaseIdToken(token: string) { try { const id = await FirebaseAdmin.getInstance().Auth.verifyIdToken(token); return id.uid; }그후 사용자가 어떤 api요청을 보낼 때 verifyFirebaseIdToken 함수에에 있는 verifyIdToken메서드를 통해 아까 받은 accesstoken을 보내 토큰이 유효한지 검사합니다. accessotken이 유효하면 id를 주어 api에 함께 보내 api 요청을 성공시킵니다.이 과정이 맞나요?질문 2. const id = await FirebaseAdmin.getInstance().Auth.verifyIdToken(token);verifyFirebaseIdToken에서 유효성 검사를 할 때 token이 로그인할 때 받은 accesstoken과 동일한 token인가요?질문 3.firestore에 accesstoken은 저장되어 있지 않던데 어디에 저장되어 있는 건가요?질문 4.코드에 accesstoken으로 인증하고 유효성 검사하는 것이 있는데요 따로 refreshToken은 없는데 firebase auth는 refreshtoken 시나리오는 잘 안하나요?질문 5.코드에는 브라우저에 쿠키나 로컬스토리지를 사용하지 않음에도 브라우저를 껐다가 다시 켜도 로그아웃 되어있지 않고 로그인이 되어있는데 어떻게 가능한 것인가요?질문 6.지금 이 로그인이 흔히 말하는 oauth맞나요?

Can't determine type for tag '<macro name="m3_comp_assist_chip_container_shape">?attr/shapeAppearanceCornerSmall</macro>'기존에 뱀장어 그림 Android studio 사용하다가 영상 속 안내 버젼인 Fox버젼으로 바꾼 뒤 위 오류가 발생합니다.구글링을 통해 build.gradle(Module)에서 implementation 'com.google.android.material:material:1.8.0'위 코드를implementation 'com.google.android.material:material:1.6.0'이렇게 수정한 뒤에는 Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.이런 오류가 발생합니다.두 오류 전부 빌드는 진행 되고 그 후에 오류가 발생하는데아무리 찾아봐도 해당 오류에 대한 해결 방법을 찾을 수가 없어서 문의드립니다  

그림상에서 flush가 두번 찍혀있어서 매커니즘의 구동 순서가 조금 햇갈려서 그런데1번의 flush와 4번의 flush의 의미가 조금 다른건가요? 아니, flush가 두번 동작하는건가요?우선은 선생님께서 트랜잭션 커밋 요청 시 내부적으로 flush가 발생한다고 하셨습니다.flush의 동작과정이 1차 캐시의 최초 스냅샷과 수정된 Entity의 값을 비교하고 변경내용 있을 경우 저장소에 UPDATE쿼리 저장하고 쿼리를 실행하는것까지가 맞을까요?그렇다면 쓰기지연의 경우에도 동일한 매커니즘처럼 보이는데 해당 그림에서는 flush가 빠져있어서 조금 햇갈리네요..쓰기지연의 경우는 persist 동작과정중에 따로 flush를 하지 않고 1차캐시에 저장됨과 동시에 쓰기지연 저장소에도 저장된다고 설명해주셨고, 이후에 트랜잭션 커밋 요청시 내부적으로 flush가 발생하면서 쿼리가 실질적으로 실행된다는 순서로 이해했습니다.강의 내용상으로 요약해보면 [쓰기지연] persist호출 후 flush 호출persist에서 INSERT 쿼리 저장flush에서 저장된 쿼리 실행[변경감지] flush가 두번 작동첫번째 flush에서 변경감지후 UPDATE 쿼리 저장두번째 flush에서 저장된 쿼리 실행이렇게 차이가 나는걸로 이해를 했습니다.두 매커니즘이 위와 같이 약간의 차이가 있는게 맞을까요?그리고 추가적으로 엔티티 삭제 remove시에는 직전 내용인 변경감지와 동일한 매커니즘이라고 설명해주셨는데아무리 생각해도 delete의 경우에는 변경감지의 매커니즘보다는 쓰기지연의 매커니즘과 같다고 생각이 들어서 질문드립니다!질문드리기가 조금 까다로운내용이라 저의 궁금포인트가 이해가 되셨는지 모르겠네요...영속성 관리 파트의 모든 강의를 들어야 명확하게 이해가 가능한건지제가 너무 까다롭게 이해하려고 하는 건지 그래도 순서를 조금 철저히 명확하게 알아야 정확하게 JPA를 사용할수 있지 않을까 싶어 질문드리오니 너그러운 마음으로 답변 부탁드리겠습니다.

 강사님께서 application.properties는 스프링 프레임워크의 기본 동작 방식이 아니다스프링 부트 초기화 과정에서 추가 해주는 거라고 말씀해주셨는습니다. @ContextConfiguration는 통합 테스트를 위해서 ApplicationContext를 로드하고, 구성요소 클래스를 넘겨주면 빈을 등록해주는거 같더라구요 SpringApplication.run을 할경우에는Environment 구현체는 ApplicationServletEnvironment가 빈으로 등록이 되고,@ContextConfiguration로 테스트를 할경우에는Environment 구현체는 StandardEnvironment 구현체가 빈으로 등록되는걸 확인했습니다.그래서 Enviroment 구현체가 등록이 되면application.properties를 가져올수있지 않나? 라는 생각에 해당 구현체를 찾아보니StandardEnvironment 는 propertySource를 받지 않는걸 확인했습니다. 제가 궁금한건1.같은 구성 정보 클래스를 넘겨주고 빈으로 등록을 했는데 구현체가 달라지는지 궁금합니다.2.스프링부트에서 테스트를 하는데@TestPropertySource를 따로 명시적으로 메타어노테이션으로 선언해서 사용하는 이유가 궁금합니다.  

강의에서 나와있는데로 <v-navigation-drawer> 옆에 clipped를 추가하고 <v-app-bar> 옆에 clipped-left를 추가했습니다.그렇게 해도 강의와는 다르게 페이지의 네비게이션 바가 페이지 위 Application 바 밑으로 들어가지 않습니다. 어떤게 문제인지 알려주시면 감사하겠습니다

Q1. 여러 제어기가 있을 때, 우선 순위가 (0 1 1 1) 말고 (0 0 1 1) 이런 경우도 있나요? Q2. 버스에는 하나의 제어기 정보만 담기고 그게 빠르게 회전한다고 이해하면 되나요? 다시 말하면 버스에는 짧은 순간에 제어기 1데이터를 브로드캐스트하고 다음 짧은 순간에 제어기 2 데이터를 브로드캐스트 ... 이런 식 강의 꼭 완강하겠습니다~감사합니다.

저장의 경우에 persist 이후 transaction commit시점에 쿼리를 날린다고 하신건 이해가 됬습니다.혹시 그렇다면 find시에는단순히 find해서 영속성을 두번 조회할때 로직 절차상으로는 member1을 영속화 하면서 1차캐시에 저장해둠과 동시에 SELECT쿼리가 나가고 member2를 조회할때 1차캐시에서 조회하는것에 대해서 이해가 되었습니다혹시 이때에는 갱신에서의 절차와 같이 아래의 트랜잭션 commit과는 연관없이 find()시 바로 영속화와 Select쿼리를 동시에 날리는것인가요?그리고 하나 더, JPA를 떠나서 스프링에서 데이터 처리를 하는 경우 readOnly=true 옵션인 SELECT에는 트랜잭션을 걸지 않아도 상관이 없는것 인지도 궁금합니다.보통은 전체단위로 트랜잭션을 readonly default로 걸어주고삽입 혹은 삭제 등의 갱신에서 추가적으로 readOnly=false옵션을 걸어주는방식으로 개발을 진행해왔습니다.

안녕하세요, 수업은 다 듣고 실습부분만 조금씩 다시 따라가고 있는데요,카트레이싱에서 환경 구축을 다 하고, KartAgent 코드도 깃허브에 있는거 그대로 C# 코드 옮기고, AcadeKart 코드도 수정을 다 했는데, 이상하게 카트가 1번 웨이포인트 지나고 리셋이 됩니다. 파이토치와 유니티 책에는 OnEpisode 함수에 for문이 있는데, 넣고 빼고는 상관이 없더라구요, 웨이포인트를 이어가지 못하거나 중간에 충돌이라고 판단하거나 기타 리셋 조건이 문제인것 같은데, 어딜 봐야 할지 조언을 주실 수 있으신가요? 

10분 40초쯤에 recomm_list li에 중앙 정렬을 위해 padding값을 주는 것 같은데 padding : 34px 35px 0 으로 어떻게 계산되는건지 궁금해요!혹시 다른 방법으로 정렬을 할 수 없을까요??

안녕하세요? 먼저 좋은 강의 감사드립니다. 실무에 많은 도움을 받고 있습니다.OAuth2.0 Roles(Resource Owner, Resource Server, Authorization Server, Client)의 개념에 대해 궁금한 점이 생겨서 아래 예시와 함께 질문드립니다.카카오톡과 연동한 게임을 보면 게임내 순위 화면에 카카오톡의 프로필 사진이 사용되는 것을 알 수 있는데요.이 경우 카카오톡의 OAuth2.0 인가 서버가 사용자 인증의 역할과 함께 리소스 서버(프로필 사진 제공)의 역할도 함께 수행하는 것으로 보이는데요 이게 맞을까요?감사합니다.

안녕하세요. 선생님의 강의를 열심히 듣고 있는 직장인입니다.다름이 아니라 설계도면에서 특정 기호를 찾아야 하는 업무가 있는데 Selective Search를 이용하여 특정 기호의 이미지를 먼저 인식시키고, 그 다음에 입력되는 도면들에서 해당 기호가 있는 곳을 표시하는 작업을 해보고 싶습니다.해당 방법을 이용하면 될지, 아니면 더 좋은 방법이 있을지 문의드립니다.

선생님 안녕하세요공유 자원과 임계구역 강의를 듣다가 9:58분 정도에 T1 eax 레지스터가 0으로 대입된다고 말씀해주셨는데 이전에 eax 값이 1이 증가한 후 suspend를 해서 다시 돌아오면 eax값이 1인 상태일거 같은데 1이 대입되어야 하는게 아닌지 궁금합니다.Thread 단위의 context switching이 일어날 때 레지스터 데이터들이 보존이 되는지도 궁금합니다..
