1. 강의를 듣던 와중 /auth/logout 라우터 부분에서 req.logout() 이부분 설명 하실때 이 메소드가 세션쿠키가 서버에서 지워진다고 하셨는데 이 의미가 정확히 무엇인가요? 2. 저는 로그인 과정에서 세션에 세션쿠키가 저장되고 브라우저로 세션쿠키가 들어갔기 때문에 브라우저의 다음 요청부터는 세션쿠키가 함께 보내져서 서버가 그 요청을 누가 보냈는지 알게 되는 식으로 강의를 이해했는데 그러면 로그아웃시 req.logout()이 메소드는 브라우저의 세션쿠키를 지워주는 메소드로 생각되는데 제가 이해한 내용 중에서 잘 못 이해한 내용이 있나요..? 

어느덧 여기까지 왔어요 ㅎㅎ 이번 강의도 즐겁게 듣겠습니다. 항상 잘 듣고있어요

안녕하세요 강의 정말 재미있게 스프링핵심 원리, JPA 잘 듣고 있습니다.  주문 목록 검색 form 태그에 action 속성이 없는데 submit을 할경우 어떤식으로 작동하는지 이해가 잘 안가여 질문드립니다.

기본적인 기능을 갖춘 웹페이지서버를 AWS를 통해서 배포하려고합니다 !! 근데 가격책정하는 부분이 너무 많아서 잘못건드릴까봐 겁나기도하고 용량을 어느정도로 잡아줘야할지도 잘 감이안와가지고 ㅠㅠ 혹시 이런부분에 대해서 알 수 있는곳 있거나 팁좀 주실 수 있으신가용 ..??

비쥬얼 스튜디오가 오류가 나는 듯 합니다. 코드에 오류나 문제는 없는것 같은데 출력값이 안나오네요... While.cpp 파일에서 Ctrl+F5했는데 이진수.exe가 실행된걸 보면 파일에 관한 문제 같은데.. 뭐가 문제일까요?

안녕하세요. 현재 Postman 강의를 듣고 있습니다. mock 서버를 생성하려고 하면 아래의 이미지와 같은 에러 메시지가 발생하는데 어떻게 해결해야 하는지 잘 모르겠습니다. [질문이미지] no mock server calls yet 이 나오면서 mock server가 생성되지 않아서 실습을 진행하지 못하고 있습니다. 이때 어떻게 해결해야 하는지 가르쳐 주시면 감사하겠습니다.

여러가지 실험을 하다가 OnHitEvent() 함수 안에다 제가 분기문을 모두 주석처리 후 State = PlayerState.Moving 으로 한 뒤 플레이를 해봤습니다.  OnHitEvent() {     State = PlayerState.Moving } 그런데 이렇게 하면 캐릭터를 한번 공격한 후 유니티짱을 다른 곳을 클릭해서 움직이려 할 때 먹통이 되어 안움직이게 됩니다. 제가 생각하기로는 OnMouseEvent로 계속해서 이벤트를  듣고 그에따른 로직을 수행해야 할 것으로 생각이 되는데 OnMouseEvent_IdleRun 내부 최상단에 debug.log를 찍어보니 해당 함수가 호출도 않되더군요 영상대로 OnHitEvent에 State = PlayerState.Idle 이면 정상적으로 수행이 됩니다만위의 사항이 아무리 고민해도 왜 그런지 모르겠어서 질문드립니다.

.close()를 왜 꼭 해야 되나요?  굳이 그걸 붙이지 않아도 실행되는데 문제가 없는데 왜 해야되는지 궁금합니다.

안녕하세요, 에릭쌤~ 대부분 최상단 네비게이션 바와 메인 배너 사이에, 그리고 메인 배너 하단에 구분선을 넣어주던데요.  사실 주위 오브젝트 색상에 따라 시각적으로 애써 보지 않으면 거의 잘 안 보이는 경우도 많던데 왜들 꼭 구분선을 넣어주나 궁금증이 들었습니다. 단순히 디자인 측면이 아니라 기능적인 용도나 특별한 이유가 있을까요?

3:37초에 한번에 컨테이너, 이미지.네트워크 모두 삭제하고 싶다라는 말은  A에서 다른환경의 B에게 보낸후에 A 에게 남아있는 컨테이너 잔여를 말하는건가요?  예를들어 카카오톡을 설치파일을 다운 받으면 설치 후에도 남아있는 install 파일이 저 쓰지않는 도커랑 비슷할까요?  커맨드도 중요하지만 중간중간 이 커멘드를 치면 이렇게 동작해 라는 이미지가 있으면 더욱 이해도가 높아질거 같습니다 흑흑 ㅠ

안녕하세요 이해하기 쉽게 알려주시는 도커 강의 너무 만족하고 잘 보고있는 학생입니다  영상을 보다가 Stop 과 Kill을 보여 의문점이 생겨서 문의 드립니다 제가 여기 강의에서 배운 도커라는 개념은  A에서 환경(버전,os...) 뭔가가 다른 환경에서 파일이나, 데이터를 컨테이너에 실어서 전송해준다 라고 이해를 하였습니다 근데 Stop 이랑 Kill 이라는 것은 전송하고 싶은 데이터를 전송하는 중에 Stop이나 Kill을 써서 중단을 한다는 말인가요? A에서 B로 배포나 뭔가를 옮길때 굳이 저 Stop과 Kill을 쓸 일이 있을지 의문입니다 어차피 통신은 양쪽다 된다는 가정하에 뭔가를 옮기는 행위를 도커라 배웠는데 Kill이나 Stop이 어디에 쓰이는지 궁금합니다 저같으면 일단 파일을 모두 보낸후에 받은 쪽에서 그냥 지울거 같습니다 통신중인걸 중간에 지우지 않고 아니면 혹시 A에서 B로 24시간 뭔가를 계속 쏴주어야 하나요??   혹시 제가 이해하고 있는 개념이 도커의 개념과 많이 다르다면  힌트좀 부탁드립니다 꾸벅  

아래와 같은 오류가 나는 이유가 뭘까요? 학생 이름을 넣어서 특정 점수를 넘는 학생에게 합격 그렇지 못한 학생에게 불합격 글자가 뜨게 하고 싶습니다. range가 초과하는 이유도 모르겠고 70점을 넘는 학생도 있는데 모든 학생이 불합격으로 뜨는 이유도 궁금합니다.
