안녕하세요. 1.  59) 인피니트스크롤에 관련해서 질문 드립니다.  하단부분 감지되었을때 이벤트가 중복 실행이 되는것 같아요. 이렇게 초기화면이 로딩이 되었다가 GET /api/post/skip/0 200 269.494 ms - 2740 감지 되면 두번 호출 하더라구요. GET /api/post/skip/6 200 263.764 ms - 2793 GET /api/post/skip/12 200 260.202 ms - 1285 ssaple.net 페이지에서도 한번 확인해보았는데 0 => 6 12 => 18 24 30(last) 이렇게 받아와지네요 2. 서버쪽은 IDE 콘솔에 잘 찍히는데 클라이언트쪽은 언제부턴가 브라우저에서 콘솔 내용이 보이질 않습니다. App.js 에서도 콘솔을 여러개 찍어도 브라우저 콘솔창에 보이질 않네요  그래서 어떤 값이 들어오는지 콘솔로 테스트를 할수가 없어서 네트워크 탭에서 확인하고 있어요 ㅠ 혹시 어떤 문제인지 아시는지 궁금합니다.!

1) sizeof와 pow함수를 이용해 short로 표현할 수 있는 숫자의 경우의 수를 표현하는 부분에서 총 2번의 뺄셈을 하셨는데 첫번째 뺄셈은 sign에 대해서 1비트를 빼준 것이고 두번째 뺄셈은 0을 표현하는 부분을 뺀 것이라고 하셨는데 이 부분이 잘 이해가 가지 않습니다. signed 와 unsigned 모두 0을 포함하는 것으로 알고 있는데 왜 0울 표현하는 부분을 뺀 것인지 궁금합니다. 2) 추가로 pow함수를 사용하실 때 std::를 사용하셨는데 pow함수를 사용할 수 있도록 <cmath>헤더를 include했는데 namespace std에 접근까지 해야하는 이유가 있는가 궁금합니다. using namespace std;를 사용했음에도 별도로 std::를 붙이시는 부분이 조금 의아했던 부분이었습니다. std와 pow함수와 서로 연관된 부분이라도 있나요?

배열에서 index에 따라 배열[index]  값 비교에서 맞으면 true false리턴은 봤는데 if(exps[i])처럼 조건문에서 이거는 해당 index에 exps[i]에 값만있으면 true인건가요  

for문을 이용해서 풀어봤는데 테스트케이스 1은 성공했지만 그 후부터는 실패했습니다. 제가 어떤게 부족한지 잘모르겠어서 질문을 올립니다. n,m=map(int,input().split())a=list(map(int,input().split()))cnt=0sum=0for i in range(len(a)): sum=a[i] if sum ==m: cnt+=1 elif sum<m: for j in range(i+1,len(a)): sum=sum+a[j] if sum==m: cnt+=1 break elif sum>m: break else: continueprint(cnt)

안녕하세요. 타일맵 강좌에서 버섯이 씬뷰에서는 나타나나 게임뷰에서는 보이지 않는 오류로 프로젝트를 새로 만들어 해결하였습니다. 현재 간단히 만들어 보려는 게임도 스프라이트가 동일하게 씬뷰에선 보이고 게임뷰에서는 안보이는데 이거 새로 만드는것 밖에는 해결방법이 없을까요?

1. 웹퍼블리셔는 거의 여성이 대다수 자리 잡고 있는 늬앙스가 있는데, 남성이 퍼블리셔를 하는 것에 대한 눈초리가 있는지 좀 궁금합니다. 2. 웹디 > 웹퍼블 > 프론트 > 백엔드 이 순서의 연봉 책정이라고 알고 있는데요, 웹퍼블 > 프론트로 넘어 가는 단계가 vuejs, react, angular 중에 하나를 제대로 다루게 되면 프론트라고 불릴 수 있는지 질문드립니다. 즉 프론트엔드 : HTML, CSS, Javascript, jquery, 프레임워크      퍼블리셔 : HTML, CSS, javascript, jquery 이 차이 인가요?

spring 프레임워크로 풀스택은 가능한데, 번번히 코딩테스트도 떨어지고 해서 우대사항맞추고싶어서 nodejs강의 시작했는데 역할은 같은거죠?

안녕하세요. 강의 내용을 활용해서 외부 api를 연동해서 연습중인데 dev 환경이라 그런지 cross origin 에러로 호출을 못하고 있습니다. 어떻게 해결을 해야할까요? 에러 로그------------------------------------------------------------------------------------------------------------ origin 'http://localhost:3060' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

안녕하세요. 좋은 수업 감사드립니다. 강의 중 몇가지 질문드리고 싶어서요. 먼저  with app.test_request_context(): 를 쓰는 용도를 좀 자세히 알려주실 수 있을까요? 왜 필요한지 아직 감이 않와서요. 둘째로 html에서 js파일이나 css파일 부를때 url_for를 쓰면 특별한 장점이 있나요?? 

#include<stdio.h> int main()  { int second = 0, minute = 0, hour = 0; while (second >= 0) { printf("Input seconds : "); scanf("%d", &second); minute = second / 60; second %= 60; hour = minute / 60; minute %= 60; while(second>=0){ printf("%d hours, %d minute, %d seconds\n", hour, minute, second); break; } } printf("good bye"); return 0; } 코드가 더 무거워져 장기적으로 봤을 떄 이런 코드는 자제하는 것이 좋을까요?

영한님 안녕하세요  영한님 책 49 ~ 50 페이지 및 SQL 중심적인 개발의 문제점 강의를 보면서 객체 그래프 내용에 관해서 궁금한게 있어서 질문드립니다. 객체와 연관관계가 있는 모든 객체 그래프를 가져오는건 현실성이 없다고 하셨는데 모든 객체 그래프를 가져오지 않는 이유가 성능 문제나, 메모리에 부담에 되서 일반적인 경우에서는 안가져오는 건가요?

질문1.   리덕스사가에 액션이 전달되는 과정 dispatch({ type: LOG_IN_REQUEST, data: { email, password }, }); 위와 같이 로그인 버튼을 눌렀을때 인자로 전달된 액션을 dispatch 하게 되는데. function* watchLogIn() { yield takeLatest(LOG_IN_REQUEST, logIn); } 이후 사가에서  LOG_IN REQUEST 에관한 액션이 왔을떄 login 함수가 실행된다는 흐름은 이해를 했습니다. 하지만 액션객체의 type 속성인 LOG_IN_REQUEST 가 어떻게 위에 takeLatest 의 첫번째 인자로 인식이되어 login 함수가 실행되는지 직관적으로 이해가 가지않습니다. 이미 사가 라이브러이에서 정해진 규칙같은 건가요 ? 액션을 디스패치 할때 {type: `액션타입`} 형태여야만 takeLatest('액션타입') 이 인식이되는지 궁금합니다. 질문2. yield function* logIn(action) { try { console.log('saga logIn'); // const result = yield call(logInAPI); yield delay(1000); => 멈춤? yield put({ => 멈춤? type: LOG_IN_SUCCESS, data: action.data, }); } catch (err) { console.error(err); yield put({ type: LOG_IN_FAILURE, error: err.response.data, }); } } yield 는 중단점 역활을 한다고 이해했습니다. 그럼 위에 takeLatest 의 두번째인자로  위 login 함수가 실행될때 첫번째 yield delay(1000) 이 실행되고 멈추는게아니라 계속에서 아래 yelid put 쪽을 실행되는부분이 이해가 잘 가지않습니다.! 영상 몇번 돌려보고 찾아도 봤는데 스스로 해결하지 못해 질문 드립니다 ㅜㅠ..  

또한 강의를 보고 강사님 깃헙들어가서 yaml을 받았는데 그거또한 에러가 납니다
