강사님! 안녕하세요! 오늘 아침부터 포스팅 쓰기 화면 및 API 구현에서 폼에 막혀 스스로 풀다... 저녁이 되야 질문드립니다 ..ㅠㅠ 아래 사진과 같이 Submit버튼을 눌러도 아무런 인터렉팅이 발생하지 않는데요... PostNewForm.js 확인 부탁드릴 수 있을까요?? ㅠㅠ https://github.com/kimsk920825/django-with-react-rev5_submit_issue/blob/post_upload_issue/frontend/src/components/PostNewForm.js

결과를 공유할때 이미지가 안나옵니다. 계속 확인중인데 잘 모르겠네요 .. 어디부분을 수정해야할까요??

안녕하세요 강사님 질문 좀 드릴께요. 강의 섹션 4.검색 UI 컴포넌트화를 진행하고 있습니다. <Search 타이핑하면 자동완성 기능을 사용하고 계시는데, 저는 아래처럼 자동완성 기능이 나타나지 않습니다. 제가 앞에서 놓쳤던 부분이 있을까요?   감사합니다.

영상 설명대로 진행하고 있는데요, 영상에서 설명해주신 부분은 전무 영문으로 작성하였는데,   Warning message: In normalizePath(path.expand(path), winslash, mustWork) :   path[1]="C:/Users/???/Documents": 파일 이름, 디렉터리 이름 또는 볼륨 레이블 구문이 잘못되었습니다   이런 경고 메세지가 계속 뒤에 이어지네요(설치는 됩니다). 처음에 윈도우 계정 이름을 한글로 해서 그런것 같은데, 계정 이름을 영문으로 바꿀경우 다른 프로그램들에 문제가 생기지 않나요? 계정이름 바꿔서 Rstudio 다시 설치하는건 크게 어렵지 않을 것 같은데, 다른 프로그램들에 문제 생길까봐 그게 걱정이네요ㅠ   + 테마 설정은 안되네요 > rscodeio::install_theme() Error in value[[3L]](cond) :    Unable to add the theme file "C:/R/R-4.1.2/library/rscodeio/resources/rscodeio.rstheme". file name conversion problem -- name too long?   이렇게 뜹니다.

제가 자바스크립트 쪽에서 promise 를 배운지 얼마 안돼 async, await 부분을 잘 모르는데요, findOne() 부분이 시퀄라이즈로 데이터를 가져오는 비동기적인 작업이라 넣어주신걸까요? 저기서 async, await  의 정확한 동작원리가 궁금한데 간략하게 설명해주실 수 있을까요..!

안녕하세요 영한님 강의 후반부에 커맨드와 쿼리 분리 라고 말씀하셨는데   여기서 뜻하는 커맨드는 어떤 것을 의미하는 것일까요?

ida pro 파일 어디서 다운받나요 자료 다운로드 경로가 확인이 안되는데요   ida 무료버전 받아도 상관없을까요?

test/widget_test.dart:16:35: Error: The argument type 'String' can't be assigned to the parameter type 'Uri'.  - 'Uri' is from 'dart:core'.     var response = await http.get('https://api.airvisual.com/v2/nearest_city?key=05dad879-fd62-46f1-bdcd-7f4e022f6b1f');                                   ^   Failed to load "/Users/goseung-wan/Documents/flutter_dust/test/widget_test.dart": Compilation failed for testPath=/Users/goseung-wan/Documents/flutter_dust/test/widget_test.dart     이런식으로 나오는데 어떤 부분을 수정하면 될까요??    url에 숫자가 포함되어서 그런건지..

안녕하세요.   이렇게 귀한 강의를 접하게 되어 매우 기쁩니다. 선생님 과정을 수강하고 있어 많은 도움이 되긴 합니다만, 한가지 문의드리고자 합니다.   CNN(또는 여타 기술)으로 instance(또는 object) segmentation 모델을 생성할때, 보통은 pre-trained 된 모델을 이용하는데요, 저만의 독특한 개체를 사진에서 segment 해야 하는 업무가 있습니다. 예를들면, 사진속에서 제가 만든 독특한 제품을 segment 해 내는 것입니다. 사람이나 고양이나 이런게 아니어서 pre-train 된 모델이 없습니다   그렇다면, train mode을 처음부터 만들어야 할텐데.. --> 맞는지요? 맞다면, 선생님의 어떤 파트를 수강하면 hint를 얻을 수 있을지 문의드립니다. 다른 과정도 괜찮습니다. 조언을 구하고자 합니다.   감사합니다.  

++ 혹시 ...  서버 실행 중 Executing (default): SELECT 1+1 AS result db 연결 성공 ------------------------------------------------------------------------------------------------ 초기 테이블 생성 중 create 관련 메시지가 안뜨고... Executing (default): SELECT 1+1 AS result 저 메시지가 뜨는데 이유가 뭘까요 ㅠㅠ. 초기 테이블 작성하고 첫 시도 입니다.

파워서비스에 로그인 하려고 하니 선생님 처럼  그냥 로그인 되는게 아니라,  Microsoft Authenticator 앱을 받고 시작하라는 말이 나옵니다. 스마트폰에 해당 앱을 다운 받은 다음부터는 뭐라 설명드리기 어려운 메시지가 계속 뜨면서 로그인이  안되고 있습니다. 참고로 파워Bi 데스크탑은 설치하였습니다. 어떻게 해결해야 할까요? 답변을 부탁드립니다.

  에러 로그는 이렇게 뜨는데 구글링을 해도 도저히 답이 안나오네요 ..       Can not load tasks for root project 'mine' org.gradle.api.internal.tasks.DefaultTaskContainer$TaskCreationException: Could not create task ':assemble'.

저번에도 typescript template를 포함한 프로젝트 생성에 관해서 질문 드렸었는데요.. 결국 해결하지 못해 manual로 생성하는 방법을 구글링을 통해 알게 되었습니다. 그 방법이 일단 react-native init 로 프로젝트를 생성 후 1. npm install typescript @types/react @types/react-native --save-dev 2.프로젝트 root 폴더에 tsconfig.json 파일 생성 후 다음과 같이 내용을 채워주는 것입니다. { "compilerOptions": { "allowJs": true, "allowSyntheticDefaultImports": true, "esModuleInterop": true, "isolatedModules": true, "jsx": "react", "lib": ["es6", "es2017"], "moduleResolution": "node", "noEmit": true, "strict": true, "target": "esnext", "skipLibCheck": true }, "exclude": ["node_modules", "babel.config.js", "metro.config.js", "jest.config.js"] } 이런식으로 typescript 프로젝트를 생성해도 native 단까지 처리 할 수 있을까요?

강의 및 pdf를 보면 모든 파라미터 받기에서 @RequestParam Map<String, Object> paramMap를 적으셨는데  Map<String, String> paramMap 이 아닌 이유는 뭘까요    혹시 변수명에 따라서 다른 타입을 꺼내주나 싶어서 ?username=memberA&age=30을 넣어줘 봤더니 paramMap.get("username").getClass().getName() 도 java.lang.String 이고 paramMap.get("age").getClass().getName() 역시  java.lang.String 이더라구요.    String 외 다양한 형태로 받아줄 게 아니라면  Map<String, String> paramMap 으로 해도 되는 거 아닐까 궁금증이 들어서 질문 드립니다 :]  

64비트 운영체제 환경에서는 모든 기본 단위나 주소 체계 등이 64비트라고 하셨었는데  조사식에서 esp는 출력이 되지만 rsp의 경우에는 '식별자 "rsp"이(가) 정의되어있지 않습니다' 라고 나오는데 왜 그런 것인지 궁금합니다..    그리고 조사식에 esp를 입력했을 때 형식은 unsigned int로 동일하게 나오지만 값이 강의와는 다르게 16진수가 아닌 10진수로 출력되는데 바꿀 수 있는 방법이 있을지도 알고 싶습니다(&c 등은 16진수로 출력됩니다) 

  Q1. REST API 구현과 테스트 강의 실습까지는 문제없이 잘 진행이 되었습니다. http GET http://localhost:8081/json_test 를 터미널 환경에서 입력하고 쥬피터 노트북에 있는 글자가 웹페이지에 잘 불러와졌습니다. 그리고 터미널 환경에서도 잘 불러와지네요.   하지만, 이번 강의 /login 부분에서 오류가 발생하네요. 스펠링을 확인하라는데 틀린부분은 없거든요.   해결책을 알려주시면 감사하겠습니다. 아나콘다 터미널 환경에서 http GET http://localhost:8080/login 으로 정확히 입력했습니다.   Q2. 원리가 궁금합니다. Flask라는 프레임워크를 활용해 서버를 구축하고 VSCode에 있는 "dave"라는 글자를 웹페이지에 띄우는게 맞는지요?   그렇다면 REST API 실습에서는 VScode가 아닌, 쥬피터노트북 환경에 있는 글자를 웹페이지에 불러왔는데 ..   이 둘의 차이점이 뭔지 헷갈립니다.

섹션 8. @Aspect AOP의 강의에서 질문드리고 싶은 내용이 있습니다. package hello.proxy.config.v6_aop.aspect; @Slf4j @Aspect public class LogTraceAspect { private final LogTrace logTrace; public LogTraceAspect(LogTrace logTrace) { this.logTrace = logTrace; } @Around("execution(* hello.proxy.app..*(..))") public Object execute(ProceedingJoinPoint joinPoint) throws Throwable { TraceStatus status = null; try { String message = joinPoint.getSignature().toShortString(); status = logTrace.begin(message); //로직 호출 Object result = joinPoint.proceed(); logTrace.end(status); return result; } catch (Exception e) { logTrace.exception(status, e); throw e; } } } 에서  //로직 호출 Object result = joinPoint.proceed(); 이 부분이 혼동이 되는 부분이 있습니다. 아래의 코드를 봐주십시오.   package hello.proxy.app.v3; import lombok.extern.slf4j.Slf4j; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @Slf4j @RestController public class OrderControllerV3 { private final OrderServiceV3 orderService; public OrderControllerV3(OrderServiceV3 orderService) { this.orderService = orderService; } @GetMapping("/v3/request") public String request(String itemId) { orderService.orderItem(itemId); return "ok"; } @GetMapping("/v3/no-log") public String noLog() { return "ok"; } }   /v3/request에 접속하는 순간 로그가 기록되고, 핵심 로직이 실행되는데요. Object result = joinPoint.proceed(); 에서 joinPoint.proceed()이 실행되면 request 메소드가 실행되고, Object result에는 "ok"라는 문자열이 저장되는 것인가요?   두서없는 질문 죄송합니다. 읽어주셔서 감사합니다.        

The operation was rejected by your operating system. It's possible that the file was already in use (by a text editor or antivirus), or that you lack permissions to access it.   If you believe this might be a permissions issue, please double-check the permissions of the file and its containing directories, or try running the command again as root/Administrator (though this is not recommended).   package.json에 복붙하고 npm i 하면 이런 식으로 에러가 뜨네요.. 깃헙에 있는 npm i -D 패키지들 이것도 마찬가지입니다 ㅠㅠ

6분56초에  li안에 a태그의 자식요소로 div가 들어가있는데 a태그는 인라인요소이고 div태그는 블록요소로  인라인요소의 자식으로 블록요소는 올 수 없다고 배웠는데  들어가도 상관없나요??
