postman에서 restapi 키까지 넣었는데 kakao openapi가 비인가되었다고 뜹니다 ㅠㅠ 이유를 잘 모르겠네요

강의를 수강하고 있는 학생입니다. 클론 코딩 예제를 학습 중에 있는데제가 먼저 코드를 작성해보고, 코딩 예제를 비교하는 방식으로 학습하고 싶습니다. 동영상 강의를 찾아가며 처음부터 다시 보는게, 조금 비효율적이라,코드 원본을 주신다면 학습하는데 큰 도움이 될 것 같습니다. 감사합니다.

안녕하세요 선생님동영상 강의를 다보고 탑뷰, PVP, 논타겟 슈팅 게임을 만들고 있습니다.그러다 이동키 관련되서 궁금한점이 생겨 질문드립니다.w,a,s,d를 이용하여 캐릭터의 이동처리를 하는데 클라이언트 프레임이 60프레임이라고 했을때 프레임마다 패킷을 서버에 보내는것은 아닌것 같았습니다. 이거에 대한 여러가지 시도를 해봤는데 결과적으로 만족스럽지않았고 삽질만 하게 되었습니다. 이거에 대한 해결방법이 있을까요?

콘솔로 데이터를 찍으면 undefined가 나옵니다 그래서 이후 강의 내용인 {data && data.fetchBoard.writer}를 해도 오류가 납니다 ㅠㅠ 무엇이 문제일까요 import { useQuery,gql } from "@apollo/client" const FETCH_BOARD=gql` query fetchBoard($number:Int){ fetchBoard(number: $number){ writer title contents } } ` export default function StacticRoutedPage(){ const {data} =useQuery(FETCH_BOARD,{ variables:{ number:3 } }) console.log(data) return ( <> <div>1번페이지 이동이 완료되었습니다!.</div> </> ) }

안녕하세요 자체 게임을 만들고 있는 1인 개발자 준비생입니다! 다름이 아니라 네브메쉬로 몬스터 이동을 구현하는데, speed가 낮을땐 몰랐는데, speed을 높이면 눈에 보일 정도로 몬스터가 떨리는 현상이 있네여 ㅠㅠ 아마도 플레이어의 위치가 실시간으로 바뀌니 이동 위치가 계속 바뀌어서 그런것 같은데 해결 방법이 있을까용?? 강사님 메리 크리스마스~!

클라이언트가 POST 방식으로 /order URI에 값과 함께 요청을 보내고, 302 Found로 응답받아 /order-result/19에 자동 리다이렉트 되었다면, /order-result/19 URI를 나가기 전까지 리다이렉션이 유지되나요? 리다이렉션이 된 후 새로고침할 때만 리다이렉션이 적용되고, /order-result/19 페이지를 나가서 다시 /order 페이지를 들어오면 주문창이 새로 뜨고 리다이렉션은 없어지는 걸로 이해를 했습니다. 제가 이해한 것이 맞는지 확인하고 싶어 질문을 남깁니다.

안녕하세요. 좋은 강의 만들어주셔서 덕분에 알고리즘 공부를 수월하게 하고 있습니다. 다름이 아니라, 문제 풀이하는 방법은 강의와 유사하게 하였습니다. 저는 DFS를 활용할 때 선택된 피자가게의 index가 아닌, 객체 자체를 selected 배열에 넣는 방식으로 진행하였습니다. 예제와 똑같은 출력값이 나왔으나, 시간 초과라고 하여서 강의와 아예 똑같은 코드를 쳐봐도 시간초과라고 나옵니다. 아래에 첨부한 코드는 초반에 제가 입력한 코드인데, 어느 부분에서 시간초과가 나는 건지 알려주실 수 있을까요? class Dis{ public int x, y; public Dis(int x, int y){ this.x = x; this.y = y; } } public class Code27 { public static int n, m; public static int min = Integer.MAX_VALUE; public static ArrayList<Dis> house, pizza; public static Dis[] selected; public static void main(String[] args){ Scanner sc = new Scanner(System.in); n = sc.nextInt(); m = sc.nextInt(); house = new ArrayList<>(); pizza = new ArrayList<>(); selected = new Dis[m]; for(int i=0; i<n; i++){ for(int j=0; j<n; j++){ int location = sc.nextInt(); if(location==1) house.add(new Dis(i, j)); else if(location==2) pizza.add(new Dis(i, j)); } } DFS(0,0); System.out.println(min); } public static void DFS(int L, int start){ if(L==m){ min = Math.min(min, distCalc(selected)); }else{ for(int i=start; i<pizza.size(); i++){ selected[L] = pizza.get(i); DFS(L+1, start+1); } } } public static int distCalc(Dis[] selected){ int sum = 0; for(Dis h : house){ int dis = Integer.MAX_VALUE; for(int j=0; j<selected.length; j++){ dis = Math.min(dis,(Math.abs(h.x - selected[j].x) + Math.abs(h.y - selected[j].y))); } sum += dis; } return sum; } }

로지스틱 회귀 기반으로 타이타닉 생존자에 대한 '분류'를 한다고 하셨는데,회귀와 분류는 엄연히 다른데 이런식으로 혼용해서 쓰이기도 하는지 궁금합니다.

안녕하세요 선생님 강의 수강 중 질문이 3가지 있어서 질문드려요 !  Post Entity 생성에서 body 컬럼을 이렇게 만드는데요.@Column({nullable: true, type:"text"})body: string;Q. body는 string 이란것을 명시했는데 type:"text"를 따로 입력한 이유가 뭔가요 선생님~? 그리고 궁금한게 또 있습니다.@Column() @ManyToOne(()=> Post)post: Post;Q. Vote Entity 생성에서 post 컬럼을 만들 때 ManyToOne 데코레이터를 쓸 때 왜 타입만 명시하는건가요?Post Entity 에서는 @ManyToOne(() => User, (user) => user.posts) 이렇게 사용하는데요 ㅠ 마지막 질문 입니다. Comment Entity 속 코드 인데요 reduce메소드에서 || 연산자가 어떻게 동작하는 지 궁금합니다. || or 연산자니까 (curObject.value || 0) 는 true or false 인데 Q. 왜 curObject.value 만 쓰지 않고 curObject.value || 0 을 더했는 지 궁금합니다 ㅠㅠ @Expose() get voteScore(): number { const initalValue = 0return this.votes?.reduce((prevValue, curObject) => prevValue + (curObject.value || 0), initalValue) }   

선생님 빨간 줄 어떻게 해결해야 하는건지요..?구글에 찾아보니까 ojdbc 필요하다 해서 저는 mysql 사용하려고 하니까 mysql 커넥터 j를 빌드패스에 추가했습니다..소스는 선생님 깃허브 그대로 가져왔습니다.

1. 책 - 기술 서적 선택 순서자바 기본서 추천에 대해서 / 대표적인 기본서 비교이 링크의 글이 삭제되었습니다!다른 링크로 대체해야될거같아요

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예(저번시간 내용과의 응용)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 예3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]저번 시간에 공부한 LoginCheckInterCeptor와 이번 시간에 배운 오류 페이지를 응용하여 적용해보려고 하니 먼저 로그인 페이지로 이동한 다음 404 에러 페이지로 이동하게 되었습니다. 이 경우 WhiteList 인터셉터를 따로 만들어 404에러(잘못된 URL)를 먼저 체크 할 수 있도록 하는 방법으로 해결하려고 구상하고 있습니다. 이 방법으로 해결하는게 맞나요?

강의 자료를 열어보니 pdf 파일로 목차만 나와있던데 모든 자료가 나와 있는 강의 자료가 있다면 부탁드립니다! xmsd888@naver.com입니다 감사합니다!
