_app.js에서 ts에러가나는데요,  Helmet밑에 빨간줄이 그어지길래 보닌깐 내용은  JSX element type 'Helmet' does not have any construct or call signature. ts(2604)로 나타납니다. - 현재 postman을 봤을 때 Helmet으로 추가한 meta내용이 나타나는 것으로 봐서는 SSR은 정상적인 것 같고,   - 제가 보는 Front에서도 Elements 탭에 확인하면 meta내용이 들어가 있습니다. 질문 : 크게 문제는 없어보이는데, 저 타입스크립트 에러메시지 내용이 잘 이해가 안되서 질문드립니다.

part1부터 정주행 중입니다. 지금 UI까지 본 상태에요. 현재 UI를 호출할 때는 프리팹을 Instanciate로 생성하고, 끌 때는 Destroy로 파괴하는 방식을 사용하잖아요? RPG에서 인벤토리 같은 UI는 대부분 아이템을 버리거나 옮기는 등의 동작이 가능한데, UI를 파괴했다가 다시 생성하면 항상 초기 값으로 호출됩니다. 혹시 씬에서 변경한 오브젝트나 변수 등이 씬에서 파괴된 후에도 남아 있도록 프로젝트 자체에 저장하는 방법은 없나요?

안녕하세요 . 4강에 팔부분 구현하는부분을 하고있습니다. 선생님의 강의를 따라한다고 하고 따라했습니다만.. 팔쪽을 구현하고 실행을 하였는데 animator에서  Hand_Weapon_in -> Hand_Idle로 자동으로 넘어가지지가 않습니다.. 이럴경우 어떠한 부분을 확인해야할까요?

강의 최종 완성본 파일로 비교를 좀 해보고 싶습니다. 중간중간 하다가 변수가 많이 생겨 월드 아웃 라이너가 이전에 만들어 놓은게 사라지는 등 강의를 처음부터 3번 이나 반복하며 듣고 있는데 항상 중간 중간에서 문제가 발생해서 끝까지 강의를 들을 수 가 없습니다. 강의 최종 완성본 파일을 올려주세요

안녕하세요 잘 듣고 있습니다. 그런데 server client폴더로 나누고 여태 저희가 한 것들을 다 server폴더에 옮겼는데요, 그렇게 바로 옮겨도 되는건가요? 나중에 npm run backend 혹은 npm run start를 할 때 문제가 발생하는 거 아닌가요? 아니면 이후 강의에서 이것들을 정리하는 시간이 따로 있나요?

EntityModel 객체를 상속하고 EntityModel 내부를 뜯어보았을 때 of 메소드 패턴을 가지고 있고, EventResource는 Event라는 도메인에 종속된 객체이기 때문에 아래와 같이 처리하였습니다. public class EventResource extends EntityModel<Event> { private static WebMvcLinkBuilder selfLinkBuilder = linkTo(EventController.class); private EventResource(){ } public static EntityModel<Event> of(Event event, String profile){ List<Link> links = getSelfLink(event); links.add(Link.of(profile, "profile")); return EntityModel.of(event, links); } public static EntityModel<Event> of(Event event){ List<Link> links = getSelfLink(event); return EntityModel.of(event, links); } private static List<Link> getSelfLink(Event event) { selfLinkBuilder.slash(event.getId()); List<Link> links = new ArrayList<>(); links.add(selfLinkBuilder.withSelfRel()); return links; } public static URI getCreatedUri(Event event) { return selfLinkBuilder.slash(event.getId()).toUri(); }}

안녕하세요 선생님Gaussian Integral을 학습하다가 궁금한 점이 생겨서 이렇게 질문드립니다. 1. exp(-x^2-y^2)을 초등함수로 표현할 수 없는 이유가 궁금합니다. 제가 이해한 바로는 simple region에서는 함수로 표현된 변수부터 적분하면 반복적분이 항상 가능한 것으로 알고 있는데요. 따라서 영역D는 x-simple이자 y-simple이기에 직교좌표계에서도 반복적분으로 이중적분을 구할 수 있다고 생각합니다.  그렇다면 저 적분값을 초등함수로 표현할 수 없는 이유는 영역 D의 특성 때문이 아니라 함수 exp(-x^2-y^2)의 특성 때문인가요? 만약 그렇다면 초등함수로 표현되지 않는 함수를 적분하기 전에 바로 판정할 수 있는 방법이 있을까요?2. 가우스적분의 마지막 전개 과정에서 의문이 생겼습니다. \lim _{ a\quad ->\quad \infty  }[{ { (\int _{ -a }^{ a }{ { e }^{ { -x }^{ 2 } } } dx })^{ 2 } ]} =[{ \lim _{ a\quad ->\quad \infty  }{ { (\int _{ -a }^{ a }{ { e }^{ { -x }^{ 2 } } } dx }) }  }]^{ 2 }={ (\int _{ -\infty  }^{ \infty  }{ { e }^{ { -x }^{ 2 } } } dx) }^{ 2 } 첫 번째 등호는 lim[f(x) ^ 2] = [limf(x)]^2이고, 두 번째는 연속함수의 성질과 비슷한 것 같은데 { \lim _{ a\quad ->\quad \infty  }{ { (\int _{ -a }^{ a }{ { e }^{ { -x }^{ 2 } } } dx }) }  } 이 수렴하는지 그리고 { { (\int _{ -a }^{ a }{ { e }^{ { -x }^{ 2 } } } dx }) }가 연속하는지는 어떻게 알 수 있을까요?? 질문이 글로 답변해주시엔 까다로운데 하필 또 기초적인 부분에 계속 걸려서 죄송합니다. 제가 미적분1을 너무 오래 전에 해서 지금 기억이 가물가물하네요... ㅜ ㅜ 그렇지만 항상 세심하게 알려주셔서 감사합니다 :)

안녕하세요 선생님 강의를 잘 듣고 있는 김기융이라고 합니다. SSD + Mobilenet Pretrained된 모델 로딩하여 Face Detection 하는 코드 수행 시 아래와 같은 에러가 나와서 문의드립니다. 이 에러를 해소하기 위해서는 matplotlibrc를 업데이트해야하는 지요? 만일 업데이트를 해야하면 어떻게 하는지 문의드립니다. 또한 아래와 같은 에러가 나옵니다. 이 에러는 어떻게 해소할수 있는지 문의드립니다. 항상 좋은 강의 감사드립니다. 김기융 드림

산술 연산 부분에 idx=100%2b93  입력 시 조회되서 취약할 경우  어플리케이션에서  string으로 받기 때문에 산술 연산이 불가능해야되는데 dbms 쪽에서 전체적으로 조회되서 생긴다고 이해했는데요(이게 맞는건가요?) 그럼 어플리케이션이 아닌 dbms쪽에서 대응방안을 찾아야되는건가요?

데이터 세팅에 대한 설명 부분에서 조금은 더 알고 싶은 부분 있어서 문의드립니다. 1. 예를 들어 두개의 다른 기간의 데이터가 각각의 엑셀파일로 존재한다면, (ex.매출데이터_20200101-20200131.xlsx과 매출데이터_20200201-20200228) 두 개의 파일을 임의로 하나의 엑셀파일로 합해서 데이터를 등록해줘야하나요 아니면 두개의 파일을 따로 등록해도 같은 데이터로 묶어서 확인이 가능한가요? 2. 다른 2개의 엑셀파일을 서로의 데이터를 비교 및 연산해가면서 데이터를 시각화하는 것도 가능한가요? (ex. 제품SKU데이터(원가 및 판매가)와 실제 판매된 데이터를 엑셀파일로 비교해 원가와 실제 판매된 금액으로 비교 및 연산) 강의 너무 잘들었습니다.

s_value는 클래스 내부에서 private로 선언되어 있는데 어떻게 외부에서 접근해서 초기화를 해줄 수 있는 건가요?  setValue 등으로 접근이 가능하다고 하면 이해는 하겠는데 헷깔립니다.

신청한 사람도 풀리는지 어떻게 되나요?

네 안녕하세요 ^^  8:22초까지 하여 재생눌렀는데 이렇게 되어서요 ㅎ

C#에서은 클래스 내부에서 static 사용시 초기화가 가능한데 C++은 초기화가 되지 않도록 막은 이유가 있을까요?

UI자동화 #3 강의의 13:38 부분에 여러 줄에 public을 동시에 입력하시는 모습이 나오는데요, (링크) https://www.inflearn.com/course/MMORPG-%EC%9C%A0%EB%8B%88%ED%8B%B0/lecture/35898 이 부분 어떻게 하는건지 궁금합니다. 추가로, 프로그래머 분들은 코드 작성할 때 편의성을 제공하는 단축키를 습관처럼 많이 쓰시더라고요. 사소하게는 Home/End로 해당 줄 앞뒤로 커서를 옮기거나, 변수 이름 수정(Ctrl R → R), 정의로 이동(F12), 이전으로 돌아가기(Ctrl -), 선택 영역 주석 처리(Ctrl K → C) 등등... 혹시 선생님 강의 중에 Visual Studio에서(커뮤니티에서 물어보니 어떤건 또 Rider 전용이라고...) 자주 쓰는 단축키를 정리한 내용이 있나요? 몇몇은 강의에서 언급되었지만 늘 궁금했던 부분이라 여쭤봅니당 ㅠ
