안녕하세요. 좋은 강좌 감사합니다. const enum EDirection { Up, Down, Left, Right, } const ODirection = { Up: 0, Down: 1, Left: 2, Right: 3, } as const; EDirection.Up; (enum member) EDirection.Up = 0 ODirection.Up; (property) Up: 0 // Using the enum as a parameter function walk(dir: EDirection) {} // It requires an extra line to pull out the keys type Direction = typeof ODirection[keyof typeof ODirection]; function run(dir: Direction) {} walk(EDirection.Left); run(ODirection.Right); 강의안에 있는 위의 예시를 실행해 보았는데요 마지막 줄에 walk(8); 을 실행하면 에러가 나지 않고 run(8); 은 에러가 나는 이유가 무엇일까요? 또 walk(Edirection.bottom); 이라고 실행하면 에러가 나던데 완전히 Edirection 안의 값과는 다른 8이라는 값을 넣었는데 에러가 안 나는 것이 이해가 안 됩니다. 

안녕하세요. 강의 잘 듣고 있습니다. service에  @Transactional public ResponseDTO changeAuthority(String invitedId, UserAuthority authority, Long companyId, String sessionUserId, Locale locale) { Users user = usersRepository.findByUserIdAndCompanyAndUseYn(invitedId, new Company(companyId), "Y"); user.authorityUpdate(authority); return new ResponseDTO(1, ""); }간단히 이런 코드가 있습니다. authorityUpdate는 authority 받아서this.authority = authority;해주는 부분입니다. 이 경우 당연히 변경 감지가 돼서 update가 돼야 한다고 생각하는데요되지 않습니다 지금 이 애플리케이션의 특이점이라고 한다면DB가 두 대가 붙어 있습니다그래서 쿼리dsl 사용할 때도 DB를 지정해서 EntityManager를 불러와야 했습니다저것도 그래서 안되나 싶은데 제가 확인 해봐야 할 것이 뭐가 있을까요?? 메인 DB 연결된 쪽은 잘 됩니다  findBy~ 후에 영속성 컨텍스트가 바로 끊기는거 같습니다.그렇게 생각한 이유는 getById로 해봤는데could not initialize proxy ~ no session 이런 에러가 발생하고findById 하면 에러는 나지 않는데 업데이트가 안됩니다. osiv true로 하고도 해봤습니다. 그냥 save 하면 update 되긴 하는데그건 선생님께서 알려주신 방법이 아니기도 하고대체 왜! 안되는지 궁금합니다 ㅠㅠ

안녕하세요! 질문이 묻힌 것 같아 다시 작성하는 점 죄송합니다ㅠㅠㅠ 강사님의 답변을 보고 다시 docker-compose.yml파일과 .travis.yml파일을 살펴보았습니다. 8,9강에서 Docker-full-stack-app에서는 강사님 말씀처럼 도커허브의 Dockerfile을 이용해 만든 이미지를 사용하지만 6,7강에서는 Dockerfile.dev만 사용하고 Dockerfile을 사용하는 부분은 못찾겠더라구요ㅠㅠㅠ 조금은 지엽적인 질문일 수 있겠지만 너무 궁금합니다ㅠㅠ생소한 개념이 여러개 나와서 어렵지만 강사님 강의 여러번 돌려보면서 이해해보려 노력하고 있습니다! 오늘도 감사합니다!version: "3" services: react: build: context: . dockerfile: Dockerfile.dev ports: - "3000:3000" volumes: - /usr/src/app/node_modules - ./:/usr/src/app stdin_open: true tests: build: context: . dockerfile: Dockerfile.dev volumes: - /usr/src/app/node_modules - ./:/usr/src/app command: ["npm", "run", "test"]sudo: required language: generic services: - docker before_install: - echo "start creating an image with dockerfile" - docker build -t smileajw1004/docker-react-app -f Dockerfile.dev . script: - docker run -e CI=true smileajw1004/docker-react-app npm run test -- --coverage deploy: edge: true provider: elasticbeanstalk region: ap-northeast-2 app: docker-react-app env: DockerReactApp-env bucket_name: elasticbeanstalk-ap-northeast-2-972153559337 bucket_path: docker-react-app on: branch: master access_key_id: $AWS_ACCESS_KEY secret_access_key: $AWS_SECRET_ACCESS_KEY

hth2486@naver.com 부탁드리겠습니다!!!

안녕하세요. 강의 잘 보고 있습니다.궁금한 점이 있습니다.Querydsl4RepositorySupport는 abstract class인데 왜 @Repository를 붙이는건가요? 실체 구체화할 부모 클래스에 @Repository를 붙이면 되는것 아닌가요? Querydsl4RepositorySupport는 abstract class라 객체로 생성이 안되는데 빈으로 등록이 가능한가요?이어서 setEntityManager에 @Autowired를 붙임으로써 의존성을 주입하고 있습니다. 그때에 entityManager라는 빈을 등록해주겠죠. 그런데 setEntityManager는 언제, 누가 호출하게 되는건가요?

(현재 환경은 job 스케줄링을 jenkinse로 하고 있고, 서버를 1개만 사용할 계획입니다.)스케줄링대로 5분 간격으로 여러 Job을 실행시키는 경우 1번 Job이 실행이 지연으로1번 Job 이 배치를 돌고 있는 중에 다시 1번 Job실행 순서가 오는 경우,즉, 같은 Job이 실행 중인 경우에는 같은 Job실행을 방지하고 싶은데Listener를 이용하는 방법 말고 혹시 다른 방법으로 이를 구현할 수 있는 방법은 없을까요??JobOperator.stop으로 막아야 할 거 같은데 어떤 구현객체, interface를 활용해야 할지 모르겠습니다.

강의 3분 6초 즈음에 보면function add(x: number, y: number): number;function add(x,y) { return x + y; }이렇게 함수에서의 타입을 명시하는 부분이 있는데요 강의 화면에서도 그렇고 제 에디터 상에서도 에러가 발생하는데 이유가 뭔지 잘 모르겠네요.VSCode 상에서의 에러 메시지는 다음과 같습니다.(parameter) y: any'y' 매개 변수는 암시적으로 'any' 형식이지만, 사용량에서 더 나은 형식을 유추할 수 있습니다 

수업자료가 각 섹션당 첫페이지만 업로드 되어있는것 같습니다. 제가 못찾은 건가요..?

import pymongo m = { "이름": "임권일", "나이": 31, "거주지": "울산", } conn = pymongo.MongoClient("localhost", 27017) db = conn.test col = db.members col.insert(m) 이렇게 적었는데  이런오류가뜨네요PS C:\MongoTest> python test.pyTraceback (most recent call last):File "C:\MongoTest\test.py", line 13, in <module>col.insert(m)File "C:\Program Files\Python310\lib\site-packages\pymongo\collection.py", line 3200, in callraise TypeError(TypeError: 'Collection' object is not callable. If you meant to call the 'insert' method on a 'Collection' object it is failing because no such method exists.

안녕하세요, 수업 잘 듣고 있습니다.질문입니다.카프카 실행시 데이터 무결성 확인 작업을 할 때 해당 토픽에 참조하는 값이 min.insync.replicas 를 우선 확인 하고, 그다음 acks값을 확인한다고 보면 될까요? 그렇다면 min.insync.replicas의 default 값은 무엇인지요?만약 acks=1 로 설정되어있고 해당 토픽의 min.insync.replicas=2로 설정되어 있을경우,2로 동작하는지와 같은 질문입니다.

안녕하세요!~ function calcValues(values, currentYOffest) { let rv; // 현재 씬(스크롤섹션)에서 스크롤된 범위를 비율로 구하기 let scrollRatio = currentYOffest / sceneInfo[currentScene].scrollHeight //현재씬에 전체범위분에 현재얼마나 스크롤했는지 return scrollRatio; } console.log(calcValues(values, currentYOffest)); scrollRatio 값은 변수에 담고 scrollRatio 리턴을 했잖아요... console에 scrollRatio값을 console로 찍은값이 없는데 어떻게 수치가 찍혀서 나오는건지 이해가 안가네요... 

스프링 프로젝트가 시작될때 AppConfig에 등록된 @Bean들이 활성화 되는 이유가 @Configuration안에 @component애노테이션 때문인가요? 그렇다면 @component로 인해 AppConfig클래스가 먼저 빈으로 등록되어야 @Bean들을 컨테이너에 등록할 수 있는건가요?

안녕하세요 run 할때 자꾸 gradle로 run이 되는데 junit test에서 바꾸는 방법이 어떻게 되나요 ?

강사님께서 그 전 강의에서, RetrieveAPIView에 serializer_class를 쓰는 대신, 직접 dict로 매핑시켜 구현하는 코딩 방식으로 구현해주셔서 ViewSet으로 migration하는 과정에서 serializer_class를 PostListSerializer하나만 쓰면, 다 동작이 하게끔 구현을 해주셨는데요.만약, RetrieveAPIView의 리팩토링 없이, 하나의 ViewSet으로 구현한다고 하면, 어떻게 구현을 하면 될까요? serializer_classes라는게 존재할까 싶어 DRF 공식문서를 찾아봤지만 어쨌든 CBV에선 하나의 serializer_class만 지정이 가능하더라구요. 강사님의 방법을 알고싶습니다.

안녕하세요.ssh-server 실행할 때 옵션추가된 명령어로 실행하도록 문의 답변 주셨는데요, 추가된 옵션에 대해 설명을 해주실수 있을까요?docker run --privileged --name docker-server -itd -p 10022:22 -p 8081:8080 -e container=docker -v /sys/fs/cgroup:/sys/fs/cgroup:rw --cgroupns=host edowon0623/docker-server:m1 /usr/sbin/init(볼륨에 :rw가 추가되었고, --cgroupns=host 이 추가된 것으로 보입니다)[질문]/sys/fs/cgroup 를 volume으로 설정하는 이유-v /sys/fs/cgroup:/sys/fs/cgroup:rw --cgroupns = host 를 추가해야하는 이유(이하 문서 내용 발췌)--cgroupns (API 1.41+) cgroup namespace to use (host|private) - 'host': Run the container in the Docker host's cgroup namespace - 'private': Run the container in its own private cgroup namespace - '': Use the cgroup namespace as configured by the default-cgroupns-mode option on the daemon (default)감사합니다.

좋은 강의 감사합니다! 강의 사용하는 애니메이션은 어떤툴을 사용하시는지요? 대학교 발표할때 활용하면 좋을거같아서요

따로 설정해준건 그 맥에서 400세팅하는것처럼윈도우에 파일 오른쪽버튼눌러서 모든 권한(상속) 빼고현재 사용자한테만 읽기 실행권한만 줬습니다.이게 아니면 원래 예전에는 윈도우에서 안됐는데 윈도우 11에서 부터 되는건가요???

안녕하세요. 강의 잘 듣고있습니다!다름이 아니라 요청마다 쓰레드를 생성하여 다중 요청에 대응하는 부분을 보고 질문이 생겨서 남깁니다.servlet은 서블릿 컨테이너에 의해 싱글톤으로 관리되는 것으로 배웠는데, 기존 쓰레드가 요청 1을 servlet을 사용하여 처리하고 있는 와중에 새로운 요청 2가 들어와서 새로운 쓰레드가 생성되고 servlet을 사용하려고 하면 이미 요청 1이 servlet을 사용하고 있기 때문에 사용할 수 없지 않은지 질문드립니다.감사합니다.

사업자등록증을 발급해주실 수 있으신가요 ?hsiwon1@naver.com으로 보내주시면 감사하겠습니다
