xxxService에서 사용하고 있는 메소드를 어떤 이유로 인해 클래스로 빼낸다면, 위 클래스는 @Service를 붙혀야 하나요? 아니면 @Component를 붙혀야 하나요? 예) validator @Service 어노테이션이 서비스 레이어를 표시하는 걸로 알고 있어서 @Service를 붙혀야 할 거라고 생각이 드는데 선생님은 어떻게 생각하시는지 궁금합니다!

마치 전역변수처럼 처음부터 enum 인스턴스를 생성해서 들고 있다는 의미로 이해하면 될까요?

동적할당을 이용한 방법으로  configSUPORT_DYNAMIC_ALLOCATION 선언후xTaskCreate 사용하면 BSS 영역에 task 할당이 된다고 하셨는데 동적할당은 heap 영역에 되는게 아닌가요? xTaskCreate가 BSS 영역에 할당하는 함수라면 xTaskCreateStatic 함수와 다름이 없을거같다고 생각됩니다. heap 영역(동적메모리)에 굳이 할당하고 싶다면 어떤 함수를 사용하면 되나요?   BSS는 정적메모리영역인데 동 heap 영역에 할당하면 좋은점이 있을까요?

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예/아니오)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오)[질문 내용]여기에 질문 내용을 남겨주세요. 강의에서 중간중간 ArrayList를 List(ArrayList의 인터페이스)로 반환하거나, 테스트케이스 작성에서 MemoryMemberRepository의 인터페이스인 MemberRepository로 선언해서 사용하는 등, 인터페이스를 선언하고 사용하는 이유가 뭔가요? 업캐스팅과 비슷한 개념으로 인터페이스를 갈아끼우기 쉽게 하기 위해서 인가요? 이것도 업캐스팅의 일종으로 볼 수 있을까요?

감사합니다

선생님 안녕하세요 좋은 강의 감사합니다.   cifar100 이미지를 사용해서 모델을 돌려보고 싶은데, 매번 다운받으려니 시간이 너무 오래걸리더라고요 혹시 cifar100 이미지를 다운받아놓고 불러다 쓸 수 있는 코드가 있을까요? 인터넷을 찾아보니 pickle 이런것을 사용해서 풀기는 하는데, batch 마다 풀거나, 아니면 코드가 너무 복잡해서   (train_images, train_labels), (test_images, test_labels) = cifar10.load_data() 이렇게 딱 한줄로 푸는 방법을 알려주시면 정말 감사하겠습니다!

읽어보니 16.8.5에 의존한다고 나오는거 같은데 설치과정에서부터 막혔는데 혹시 해결방법이 있을까요..  

안녕하세요 선생님. 현재 제가 업무에서 전자정부프레임워크를 활용하고 있는 신입개발자입니다.  현재 저희 프로젝트는 외부업체가 제공하는 지니웍스CMS를 활용해서 관리자페이지도 구현하고, 웹사이트를 구성했는데요. 사용자가 로그인오류가 났을때, 관리자페이지에서 비밀번호를 임시발급하는 버튼이있더라구요.  하지만 뭔가 CMS가 제공하는 기능만 이용하기에는 찝찝해서 그 원리를 알고싶은데요...   뭐가 궁금하냐면,  예를들어 사용자가 회원가입하면 DB에 해시로 비밀번호가 저장이되는데, 이때, 위에서 언급했듯이, 사용자가 로그인오류땜에 접속이안되고, 개발자 역시, DB에 해시번호로 비밀번호가 저장되어있으니, 어떻게 임시로 비밀번호 컬럼을 UPDATE로 수정 못하잖아요. 해시로 저장하는것이 개발자도 사용자의 계정으로 로그인 못하도록 법적으로 되어 있다고 알고있는데...   이러한 상황을 종합적으로 봤을떄, 임시 비밀번호를 어떤식으로 발급을 해줘야하는거죠??  (임시 비밀번호를 생성하는 로직은 알고있슴다.)     그냥 단지 CMS가 제공하는 '임시비밀번호 발급'버튼으로 임시 비밀번호를 발급하는것이 정신에 좋은걸까요. 신입이라 CMS를 첨봐서, 질문드려요. 괜히 제가 복잡하게 알 필요도없는걸 알려고 하는건지 궁금합니다!     

Configuration 서버의 정보가 변경이 됐을 때 정보를 다시 가지고 오는 방법들이 있는데 두번째 방법인 actuator를 이용하는데 refresh, health, beans 전부 안됩니다.   health_check로 값을 확인하면 아래처럼 잘뜹니다. It's Working in User Service, port(local.server.port)=56550, port(server.port)=0, token secret=user_token, token expiration time=86400000     참고로 user-service에 bootstrap.yml 파일은 spring: cloud: config: uri: http://127.0.0.1:8888 name: ecommerce # ecommerce.yml 파일을 가져온다.   git-local-repo에 있는 ecommerce.yml은 다음과 같습니다. token: expiration_time: 86400000 secret: user_tokengateway: ip: 192.168.45.163   그리고 config-service에 있는 application.yml 파일은 server: port: 8888spring: application: name: config-service cloud: config: server: git: uri: file://C:\Users\test\IdeaProjects\Inflearn\msa\git-local-repo 다음과 같습니다. 그런데 actuator 방법은 /health와 /beans 모두 Whitelabel Error Page가 뜨고   /refresh로 post 요청하면 {     "timestamp": "2022-08-20T11:28:26.532+00:00",     "status": 404,     "error": "Not Found",     "message": "No message available",     "path": "/actuator/refresh" } 위와 같은 에러가 발생합니다.. 참고로 user-service의 application.yml에 management: endpoints: web: exposure: include: refresh, health, beans 을 추가했습니다. 그런데 강의처럼 자동완성은 전혀 뜨지 않았습니다. endpoints 부터 자동완성이 없었습니다. 대체 왜이런걸까요?     그리고  user-service에서 실행시키면 도대체 왜 config-service 프로젝트에 있는 application.yml 파일에 등록된 `uri: file://C:\Users\test\IdeaProjects\Inflearn\msa\git-local-repo` ( 제 ecommerce.yml 주소) 이 주소를 읽는건지 모르겠습니다. user-service의 bootstrap.yml에는 ecommerce(.yml) 밖에 없는데… 저 config-service에 있는 application.yml을 참조 하라는 표시를 대체 어디에 한건가요??  

원래 이런가요? 변화는 잘 되는데..    body {     font-family: 'Noto Sans KR', sans-serif;     line-height: 1.5em;     margin:0;     font-weight: 300;     display: flex;     justify-content: center;     align-items: center;     height: 100vh;     color: #222; } a {     text-decoration: none;     color: #222; } .container {} input[id=trigger] {     display: none; } label[for=trigger] {     width: 40px;     height: 30px;     display: block;     position: relative;     cursor: pointer; } label[for=trigger] span {     position: absolute;     height: 2px;     background-color: #000;     width: 100%;     left: 0;     transition: 0.3s; } label[for=trigger] span:nth-child(1) {     top: 0; } label[for=trigger] span:nth-child(2) {     top: 50%; } label[for=trigger] span:nth-child(3) {     top: 100%;     /* top: calc(100% - 2px); */ } input[id=trigger]:checked + label[for=trigger] span:nth-child(1) {     top: 50%;     transform: rotate(45deg); } input[id=trigger]:checked + label[for=trigger] span:nth-child(2) {     opacity: 0; } input[id=trigger]:checked + label[for=trigger] span:nth-child(3) {     top: 50%;     transform: rotate(-45deg); }

vsc에서 함수에 커서를 두고 F12를 누르면 그 함수가 정의된 곳으로 이동을 하는데요 자바스크립트 함수를 찾고 싶은데 js파일 간에 찾는건 되는데 .php파일에 선언 된 함수는 찾지를 못하네 예를 들어 function.php파일에서 aaa라는 함수를 선언하고test.php파일에서 aaa함수를 호출한다고 했을 때 test.php파일의 aaa함수에 커서를 두고 F12를 누르면 function.php파일로 가야 정상인데 작동을 하지 않네요ㅠㅠ 해결 방법이 없을까요?

안녕하세요 강사님 게시글 포스트 관련 내용입니다. Addpost Request > Success 과정에서  data값이 undefined 되는 에러가 있습니다. 질문게시판과 구글링으로 찾아봤지만 해당 내용을 찾기가 힘들어 질문 남깁니다.   추가로 Failed prop type Warning이 떠서 관련 코드 스크린샷 및 깃헙 주소 첨부 드립니다. 감사합니다. * 깃헙 주소: https://github.com/Benarr/twiffer   <Console창 오류메세지>     <componets 폴더 - PostCard.js>   <components 폴더 - PostCardContent.js>   <reducers 폴더 - post.js>
