  다른 네임스페이스에 접속하면 세션ID가 변합니다. 어떻게 해결해야 하나요? axios나 cookie-signature같은 건 교과서보면서 그대로 따라 했습니다. const signedCookie = cookie.sign( req.signedCookies['connect.sid'], process.env.COOKIE_SECRET );     const connectSID = `${signedCookie}`;     console.log('연결ID :', connectSID);     axios.post(`http://localhost:8005/room/${roomId}/join`, {       headers: {         Cookie: `connect.sid=s%3A${connectSID}`       }   }) app.use((req, res, next) => {     if (!req.session.color) {       const colorHash = new ColorHash();       req.session.color = colorHash.hex(req.sessionID);     }     console.log('세션ID: ', req.sessionID);     console.log('유저ID: ', req.session.color);     next(); }); 이상한점은 채팅을 칠 때에는 처음 받은 세션으로 등록됩니다. 입장과 퇴장 시에만 세션이 변경됩니다  

안녕하세요! 이번 실습에서 axios를 통해 상품데이터를 받아와서 화면에 보이게 하는 과정을 하다보니 기존에 products 변수에  직접 객체들을 작성하여 화면에 나타내는 것 보다 느리게 화면에 올라오는 것을 볼 수 있는데요. 이건 그냥 mock server를 통해 받아와서 그런거라고 이해하면 될까요? 상품이 세가지 밖에 없는데, 로딩 속도가 현저히 떨어지는 것이 의아하여 질문드립니다!

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.   안녕하세요 비슷하면서도 slice와 map을 이용해서 문제를 풀었는데 시간복잡도상으로 slice가 들어가면서 더 좋지 않은 방식으로 풀게 된걸까요? function solution(arr1,arr2){ let answer =[]; let n=0,m=0; while(true){ if(arr1[n]<arr2[m]) { answer.push(arr1[n]) n++ if(n>=arr1.length){ arr2.slice(m,).map(data=>answer.push(data)) break; } } else{ answer.push(arr2[m]) m++ if(m>=arr2.length){ arr1.slice(n,).map(data=>answer.push(data)) break; } } } return answer; }

  #include <iostream> #include <vector> using namespace std; int n = 0, ch[11], l[11]; vector<int> v; void DFS(int L) { if (L == n + 1) { int sum = 0; for (int i = 1; i <= n; i++) { if (ch[i] == 1) { sum += l[i]; } } v.push_back(sum); } else { ch[L] = 1; DFS(L + 1); ch[L] = 0; DFS(L + 1); } } int main() { //FILE* fp = nullptr; //freopen_s(&fp, "input.txt", "rt", stdin); cin >> n; for (int i = 1; i <= n; i++) { cin >> l[i]; } v.push_back(0); DFS(1); int s = v.size(); for (int i = 1; i <= s/2; i++) { int l = v[i]; int r = v[s - i]; if (l == r) { cout << "YES"; return 0; } } cout << "NO"; return 0; } 트리의 정가운데를 기준으로 나눠서 생각해보면  반대편에 있는 값이 서로 겹치지 않는 값이더라구요. 위 특성을 활용하면 이런 풀이도 가능한 것 같습니다.    

바보같은 질문일 수 있겠지만 용기내어 해보겠습니다. 일단 저는 슬리액 백, 프론트 둘 다 구매해서 듣고있습니다. 슬리액 프론트 백을 참고해서 다른 프로젝트에 적용시켜보고 있는 과정에서 궁금한점이 생겼습니다.  여기서 mutate에 데이터를 넣고 swr data에 로그인 된 데이터가 들어가는걸로 이해를 했고, http://localhost:1010/auth/ 에서 GET 으로 API를 요청해서 데이터를 받아와서 페이지에서 유저가 로그인 되어있음을 알 수 있다고 이해했습니다.그런데 서버단에서는 위에 있는 코드로 GET 요청을 해서 유저 정보를 가지고 오는건데 유저를 찾는 부분도 없는데 어떻게 들고 온다는 건지 모르겠습니다.  

안녕하세요, 강의 잘 보고 있습니다.   BlockOperation 자체는 Operation에 등록된 block들이 concurrent하게 실행된다고 나와 있고, 이걸 serial하게 실행하고 싶으면 이 BlockOperation을 maxConcurrentOperationCount를 1로 설정한 OperationQueue에 넣으면 된다고 하신 걸로 이해했습니다. 그래서 다음과 같이 코드를 작성하고 돌려봤는데, 등록한 block의 순서대로 print되지 않는 걸 봐서는 serial하게 실행되지 않는 것 같습니다. let operation = BlockOperation() for i in 0 ..< 1000 { operation.addExecutionBlock { print(i, Thread.current) } } let queue = OperationQueue() queue.maxConcurrentOperationCount = 1 queue.addOperation(operation) 이 코드를 실행하면 i가 0부터 999까지 순서대로 프린트되지 않고 랜덤하게 프린트됩니다. let queue = OperationQueue() queue.maxConcurrentOperationCount = 1 for i in 0 ..< 1000 { queue.addOperation { print(i, Thread.current) } } 반면에 위처럼 BlockOperation을 사용하지 않고 maxConcurrentOpreationCount가 1인 OperationQueue에 block을 순서대로 추가하면, 이전에 설명해주신 대로 serial하게 실행되어 0부터 999까지 차례대로 프린트됩니다. Thread.current의 프린트 결과를 봐도 두 번째 코드보다 첫 번째 코드에서 더 많은 쓰레드를 사용하는 것으로 보입니다.   (질문과는 관계 없긴 한데, 이 과정에서 OperationQueue가 항상 동일한 쓰레드를 사용해서 Operation을 실행하지는 않는다는 것을 확인했습니다. 반면 serial하게 동작하는 커스텀 DispatchQueue는 항상 동일한 쓰레드를 사용하는 것으로 확인했습니다. maxConcurrentOperationCount가 1인 OperationQueue는 항상 동일한 쓰레드를 사용하지는 않더라구요. 사실 maxConcurrentOperationCount가 말 그대로 concurrent하게 실행될 수 있는 Operation의 개수를 말하는 것이지, 실행될 수 있는 쓰레드의 개수를 말하는 건 아니니까 이건 이것 나름대로 이해한 것 같습니다.)   executionBlocks를 얻어서 좀 더 봐보려고 했는데 잘 안되더라구요. 혹시 이 부분 관련해서 제가 잘못 이해한 부분이 있는지, 아니면 추가 설명을 부탁드릴 수 있을까요? 감사합니다.

안녕하세요. 작업형 2유형에서 강의 주신 범위에서는 train과 test가 주어지던가 X train, Y train, X test로 주어지는 두 가지 방향에 대해서 말씀 해주셨는데요.   만약 train data 한 개만 주어지는 경우도 생길까요? 이러한 경우,   x_train, y_train, x_test, y_test를 각각 나누어 예측 및 분류 모형을 만들 수 있도록 data partition 코드 설명 가능 할까요?

제목과 같습니다.맥북-아이패드 사이드카로 강의 시청시 화면이 검게 나옵니다. 일정 시간 시청 후(아마 5분 짜리 강의 한개 들은 후 다음 강의 수강 시)에 검은 화면에서 화면이 보이지 않네요.모든 강의가 그렇습니다. 맥북 에어라 화면이 작아서 사이드카로 보려는데 위 문제 발생해서사이드카를 해제해보니 바로 정상적으로 나왔습니다. 아이패드 앱으로 보기엔 앱이 불편해서 사이드카로 보려는데.. 문제가 생기네요 ㅠ이전에 사이드카로 들었을 때는 문제가 없었습니다. 확인 부탁드립니다.

리액트 프로젝트를 할 때 모두 CRA로 초기 세팅을 잡고 시작했었는데 이번에 강의를 수강하게 된 이유가 CRA로 세팅하지 않고 처음부터 세팅한다는 점에 있었는데요, 그래서 alecture 폴더를 모두 지우고 다시 만든 후 npm init을 쳤는데 그대로 소스가 옮겨져오더라구요 컴포넌트 폴더 , 페이지 폴더 등등 하위 소스까지 모두 다요 혹시 어떤 부분 때문에 이렇게 모두 다시 생성이 되는지 여쭤봐도 될까요? git clone 이후 진행하였습니다.

    이부분에서 foreach없이 사용하는데도 작동되는게 너무이해가 안갑니다 그리고 PageBean도 마찬가지로 Foreach문을 선언해주지 않았는데도 처리되는게 혹시 preHandle에서 topMenuList 때문일까요?

import java.util.Scanner;public class Main { public static void main(String[] args) { Main T = new Main(); Scanner scanner = new Scanner(System.in); int count = scanner.nextInt(); String input2 = scanner.next(); System.out.print(T.solution(count, input2)); } public String solution(int count, String str) { String answer = ""; StringBuilder temp = new StringBuilder(); int c = 0; for (int i = 0; i < str.length(); i++) { if (str.charAt(i) == '#') { temp.append(1); } else { temp.append(0); } c++; if (c == 7) { int codePoint = Integer.parseInt(temp.toString(), 2); String 해독한문자 = Character.toString((char) codePoint); answer += 해독한문자; temp = new StringBuilder(); c = 0; } } return answer; }} 풀다보니 같이 입력받은 숫자가 필요없어졌네요... 그래도 강사님 풀이가 훨 간단하네요..    

안녕하세요.   5/31일에 6/27 월요일 세미나 신청했는데 아직 신청 결과를 연락 받지 못 했습니다. 세미나 신청 결과를 확인해 주실수 있나요?

    일단 상품등록하는데 문제는 없습니다. 위와 연결된 Controller에 매핑과 BookForm 설정 똑같이 했는데 강의에 영한님이 한것처럼 html에서 th:object="${form}" 나 th:field="*{name}" 을 command+click 으로 연결된곳으로 갈수도 없고 Cannot resolve 'form' 오류 뜨면서 빨간줄 그어지는데 해결할수 있는 방법있을까요? 저도 그 편한 기능 쓰고 싶습니다 진짜루 ..ㅠㅠ 인텔리제이는 IntelliJ IDEA 2022.1.2 (Ultimate Edition) 쓰고 있습니다.

감사합니다.

스프링에서는 node.js의 nodemon처럼 코드가 수정될 때마다 서버를 자동으로 재시작해주는 기능이 없나요?

const f1 = (str) => { let acc = ''; for (let i = 0; i < str.length; i++) { acc += str.slice(0, i + 1) + '\n'; } console.log(acc); }; f1("*****") 먼저 명령형으로 작성한다음 함수형으로 바꾸려하는데.. 변환이 잘 안되네요..  위 코드는 어떻게 하면 함수형으로 바꿀 수 있을까요?

안녕하세요 판교님, 질문이 있습니다   1. 웹팩4 또는 5 등등 버전마다 호환이 되는 게 있고 안되는 버전이 있는 것 같습니다. npm install css-loader@3 file-loader@5 style-loader@1 각각의 로더들이 호환되는지 여부를 어디서 체크할 수 있나요? (웹팩4에서는 어디까지 호환되는지를 찾고 있는데 공식문서를 봐도 해답을 못찾겠네요)
