제공해주신 예제 파일에서는 performance tab으로 돌려보면 어떤 컴포넌트의, 어떤 메서드인지 알 수 있는데 vue app을 실행시키고 똑같이 돌려보면 "컴파일 코드" 라고만 되어 있어서 이게 어떤 메서드인지 알 수가 없습니다. 이런 경우에는 어떻게 식별할 수 있을까요? 혹은 어떤 설정을 바꾸면 될까요?

안녕하세요 늘 좋은 강의 잘 듣고 있습니다. 이번 영상에서 input과 output의 bit 수를input feature map : 8bitweight : 8bitbias : 8bit input fmap * weight : 16bit 기타등등 CNN 연산을 수행하면서 input fmap bit width는 8bit에서 output fmap의 bit width가 23bit으로 증가하는데 그러면 CNN 구조를 serial하게 연결시키게 되면 계속해서 overflow가 발생하지 않도록 bit width를 증가시키면 bit width가 마지막 CNN 구조를 통과하고 나서 기하급수적으로 늘어난다고 생각하는데이러한 경우에 중간에 어떠한 조치를 취해야하는지 궁금합니다. 감사합니다

 안녕하세요. 강의 잘 듣고 있습니다.if (student.certification.equals("자바"))if (student.certification.contains("자바"))이렇게 해도 결과값은 같게 나오는데 보통 equals를 많이 사용할까요?!

public class SpeedCam{ public String name; public SpeedCam() { this.name = name; } } public SpeedCam() 생성자를 만들어서 this name 을 받는건데 그냥 public String name = "과속 단속 카메라"; 이렇게 쓰면 되지않나요? 왜 생성자를 써야하는지 궁금합니다.

안녕하세요 강의를 듣던 중 h2 db와 연결이 정상적으로 되지 않는 것 같아 질문 남깁니다.기존에는 1. h2.bat을 실행시키고, 2. 웹 브라우저 ip 주소를 localhost로 변경하고 3. db파일을 생성하기 위해 JDBC URL에 jdbc:h2:~/jpashop과 같이 입력하면 c드라이브 사용자 폴더에 jpashop.mv.db 파일이 정상적으로 생성 됐었습니다근데 인텔리제이를 community버전에서 ultimate 버전으로 바꾸면서 뭔가 변동이 생긴 것인지(단순 추정입니다), 현재는 위와 같은 방식으로 진행해도 db파일이 생성되지 않고 Database "C:/Users/LG/jpashop" not found, either pre-create it or allow remote database creation (not recommended in secure environments) 과 같은 에러 메시지를 출력하는 것을 볼 수 있었습니다.따라서 다른 질문을 참조해보니, https://www.evernote.com/shard/s568/client/snv?noteGuid=fb1f3c6b-e985-e08f-4523-a34e523406e4&noteKey=e3976a810c1854c90695f9cddf1ab7bf&sn=https%3A%2F%2Fwww.evernote.com%2Fshard%2Fs568%2Fsh%2Ffb1f3c6b-e985-e08f-4523-a34e523406e4%2Fe3976a810c1854c90695f9cddf1ab7bf&title=H2%2B%25EB%258D%25B0%25EC%259D%25B4%25ED%2584%25B0%25EB%25B2%25A0%25EC%259D%25B4%25EC%258A%25A4%2B%25EC%2583%259D%25EC%2584%25B1%2B%25EB%25B0%25A9%25EB%25B2%2595%2528%25EC%259C%2588%25EB%258F%2584%25EC%259A%25B0%2529 링크를 확인할 수 있었고 h2에서 db파일을 따로 생성하여 작동에는 성공하였습니다.헌데, h2에서 db파일을 따로 생성하게 되면 trace.db 파일도 생성되고, 비밀번호도 설정해주고 yml에도 설정해줘야 하는 등 추가적인 작업이 있는 것을 확인할 수 있었습니다. 물론 별거 아닌 것들이지만, 기존에 쓰던 방식이 훨씬 편리한 것 같아 기존 방식(H2 콘솔의 JDBC URL 란을 통해 db파일을 생성)으로 돌아갈 수 있는 방법을 여쭙고 싶습니다.에러 로그로 확인해 봤을 때 allow remote database creation을 해주면 될 것 같은데, 이에 대해 질의드리고자 합니다.

The guest machine entered an invalid state while waiting for it to boot. Valid states are 'starting, running'. The machine is in the 'aborted' state. Please verify everything is configured properly and try again. If the provider you're using has a GUI that comes with it, it is often helpful to open that and watch the machine, since the GUI often has more helpful error messages than Vagrant can retrieve. For example, if you're using VirtualBox, run `vagrant up` while the VirtualBox GUI is open. The primary issue for this error is that the provider you're using is not properly configured. This is very rarely a Vagrant issue.virtual box 버전이 최신에서만 m1이 되다보니.. 안되는 거 같습니다.

안녕하세요. 프로토타이핑 단계와 디자인 시스템 단계가 구분되어 있는데, 혹시 두 단계가 정확히 어떻게 다른 건가요? 디자인 시스템 단계에서 정확히 어떤 일을 하는 건지 분명하지 않은 것 같습니다. 감사합니다.

안녕하세요 정수원 선생님 질문이 있습니다.httpSecurity .csrf().csrfTokenRepository(new HttpSessionCsrfTokenRepository()); 처럼 세션에 저장하는 경우에 응답으로 csrf token 관련 정보들이 response에 존재하지 않는데해당 경우에는 custom하게 필터를 만들어서 세션에 저장후 응답에 적절한 id(csrfJSessinID?) 를 넣어줘서나중에 검증할 수 있도록 해야하나요? client 입장에서는 어떻게 csrf token을 http 요청헤더에 넣을 수 있나요?

안녕하세요 강의 잘 들었습니다 !!다름이 아니라 토큰 만료 시간을 엄청 길게(100000초) 했는데도자꾸 몇 분 만에 토큰이 만기(TokenExpiredException) 되었다고 해서 .....(프론트는Android studio랑 연동)뭔가 이상해서 혹시 이런 증상에 대해 해결책은 없는지 궁금합니다.

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예)[질문 내용]강의 잘 듣고 있습니다.실습 진행중에 EOFException이 마지막에 계속 뜨는데 무시하고 진행하면 될까요?다른 수강생분께 답변 남기신 글 보고 따라해봤는데도 해결이 안되네요

쿠버네티스에서 디폴로이먼트로 .war 파일을 배포해서 실행 시키는데 파드 안에서 컨테이너를 실행 시켜 실행시키는걸로 알고 있는데 파드안에 도커 컨테이너가 실행시켜지는건가요? 아님 어떤 컨테이너가 실행되서 돌아가는건지 궁금합니다

go func() { for i := 0; i < 5; i++ { fmt.Println("check : ", i) ch <- true } close(ch) // 5회 채널에 값 전송 후 채널 닫기 }() for i := range ch { // 채널에서 값을 꺼내온다. 닫힐 때 까지 fmt.Println("ex1 : ", i) }코드출력check : 0check : 1ex1 : trueex1 : truecheck : 2check : 3ex1 : trueex1 : truecheck : 4ex1 : true 위 코드가 아래와 같이 출력됩니다. 왜 2개씩 출력이 되는 걸까요?.. 제 생각에는 check가 0부터 하나씩 출력이 되야 할 것 같은데.. ch := make(chan bool, 2) 이렇게 버퍼(?)를 추가해 주면 3개 3을 추가하면 4개씩 늘어나네요.기본이 2개씩 모아서 실행을 하고 추가되는 값 만큼 처리를 한다고 생각하면 될까요?+) 개인적으로 강사님 의견이 궁금한 부분인데요.restAPI를 Java-Spring 대신 Go로 짠다고 했을 때 비동기가 중요한 작업이라고 하면 Go가 더 괜찮은 선택이 될 수 있을까요?
