다 알맞게 작성한거 같은데 계속 오류가 나요ㅠㅠ hostname에 퍼블릭 ip를 작성하는것이 맞을까요?강의따라서 수업 내용은 잘 따라하였습니다

섹션 9 태블로 강의 두번째도 강의 안나옵니다

섹션5 상호 조인 내용이 없어요.외부 조인 내용만 반복됩니다

수강 중 질문이 있으시면 댓글로 남겨주세요!!친절하게 답변해 드리겠습니다!! :)

서버도 켜고 인바운드 규칙도 변경했는데 서버에선 22 이 르스닝으로 방화벽이 안뚫려서 접속이 안된거 같은데 어떻게 해결하나요ㅠㅠ

안녕하세요 강사님. 섹션 0 (윈도우) Java, IntelliJ, PostMan, MySQL, git 설치영상 보면서 IntelliJ 설치중인데요설정부분에 보니까 cannot find the specified shell scripts location in the system path라는 빨간 문구가 떠 있는데 그냥 넘어가도 괜찮을까요? 

왜이런건가요??켜졌다가도 금방꺼집니다

EC2 중지후 다시 인스턴스를 실행 했는데 퍼블릭 ip주소가 바꼈습니다.그래서 다시 인스턴스 실행후 바뀐 퍼블릭 ip주소로 접속을 시도했는데보안설정도 그대로인데 접속이 안되서 보니 빌드 디렉토리는 존재하는데빌드 실행이 안된상태이고 어플리케이션도 종료가 되있는 상태였습니다 다시 빌드후 어플리케이션 재실행으로현재는 접속이 가능한 상태이지만 혹시 일레스틱을 사용하지 않는 경우나도메인을 따로 구입하지 않은경우에는인스턴스 중지후 재실행시 항상 이러한 절차를 거쳐야 하는건가요?

저는 html대신 react를 사용해서 프로젝트를 진행중인데요.단순히 html로 프로젝트를 진행할 때는 아무 이상없이 미리보기 이미지도 잘 나오고 이미지 정보도 db에 저장이 잘됩니다.그런데 react를 사용해서 하면 미리보기 이미지가 불러와지지 않습니다.그래서 구글링해본 결과 파일 경로 앞에 http://localhost:8005를 붙어야 한다, encodeURI함수를 이용해서 경로를 변환시켜줘여 한다. 등 나와있는 정보대로 해보았지만 다 안되네요..그러다가 FileReader를 사용해서 파일 경로를 데이터URI형식으로 변환해야 한다고 해서 해봤는데 이걸 사용하며는 img가 잘나오더군요. 문제는 FileReader를 사용하여 파일을 변환하면 파일의 경로가 너무 길어져 413에러가 발생합니다..그래서 리액트에서는 대체 어떻게 img를 다뤄야 할지 잘 모르겠습니다..아래 코드들은 리액트에서 다양한 방법으로 경로 설정을 하고 그 후 개발자 도구에서 복사해온 태그들 입니다.물론 한개도 제대로 나온 이미지는 없습니다1.html로 프론트를 다뤘을때랑 같은 코드(실행은 리엑트에서 하고 단순히 html로 실행하면 아래 태그는 잘 나옴)<img id="image-preview" src="img/스크린샷%202023-08-31%20오후%201.54.471694844382032.png" alt="미리보기" />2.local주소 붙이고 encodeURI로 경로 변환<img id="image-preview" src="http://localhost:8005/img/%C3%A1%C2%84%C2%89%C3%A1%C2%85%C2%B3%C3%A1%C2%84%C2%8F%C3%A1%C2%85%C2%B3%C3%A1%C2%84%C2%85%C3%A1%C2%85%C2%B5%C3%A1%C2%86%C2%AB%C3%A1%C2%84%C2%89%C3%A1%C2%85%C2%A3%C3%A1%C2%86%C2%BA%202023-08-31%20%C3%A1%C2%84%C2%8B%C3%A1%C2%85%C2%A9%C3%A1%C2%84%C2%92%C3%A1%C2%85%C2%AE%201.54.471694844547805.png" alt="미리보기"></img>이런식으로 encodeURI랑 로컬주소 고려해서 경우의 수 4가지 다 해봤는데 안됐습니다.

컨텍스트 스위칭에서 캐시 플러시가 발생한다고 되어 있는데,이는 프로세스 간의 컨텍스트 스위칭이 아니라 스레드간 컨텍스트 스위칭에서도 발생하는지 궁굼합니다.왜냐하면 스레드는 주소 공간을 공유하기 때문에 데이터 영역은 플러시해야겠지만, 명령어 영역은 플러시 하지 않아도 되는거 아닌가 생각이 듭니다. 또한 캐시를 플러시 한다는 뜻이 캐시의 데이터를 메모리에 반영하는, 즉 write-back 동작인지도 궁굼합니다.제가 검색을 통해 찾아봤을 때는 캐시 flush는 캐시를 invalidate 하여 캐시를 메인 메모리에 반영하지 않고 초기화만 하는 것으로만 나왔습니다. 그런데 캐시 플러시가 메인 메모리에 반영하지 않는다면 데이터가 없어져 버리니, 제가 알아본 개념이 잘못된 것이 아닌가 합니다. 제가 자바로 실행했을 때 역시 컨텍스트 스위칭이 발생하면서 캐시 데이터가 메인 메모리로 반영이 되고, 그 값을 가져옴으로써 스레드가 종료될 수 있었습니다.
