경로를 확실히 주었는데 vs code에서는 작동하지만 intellij 에서는 적용되지 않습니다.다른 방법은 없을까요?

#include <iostream> #include <vector> #include <cassert> using namespace std; void printVector(vector<int>& temp, const int index) { assert(index >= 3); static_assert(index >= 3, "index should be less than 3");//여기서 컴파일 에러 } int main() { std::vector<int> vec{ 1,2,3,4,5 }; printVector(vec, 3); }static_assert 에서 에러가 나는데매개변수를 const 상수화 해도 static_assert문에서 에러가 나는 이유가 뭔가요?

안녕하세요 캡틴 판교님 제가 강의를 따라서 진행을 하던중 오류를 만나서 해결이 안되서 질문 드립니다. 뭐가 문제일까요? 

 저의 풀이입니다 . 강의에서sum == total // 2이 코드에서 예외가 발생할 수 있다고 하셨는데 몫을 구하지말고바로 나누기로 해서 풀면 되지않을까요? 그리고 궁금한점이파이썬에서는 타입이 달라도 ( 16 정수타입 과 16.0 실수타입 )같다고 인식되나요?

소스코드에 server와 client에도 Dockerfile이 있던데 이걸로 Dockerlize가 되나요?

DB에 Insert 하려고 할 때 TypeOrm에서 Default 값을 넣어주지 않아 에러가 발생했습니다.(CreatedAt, UpdatedAt 컬럼) 그래서 처음에는 Database에서 Table에 Default값을 세팅하고 사용했는데요.어떤 분이 질문 하신걸 보고 다시 수정해 보는 중입니다.강의에 있는 소스는 @Column("datetime", { name: "createdAt", default: () => "CURRENT_TIMESTAMP"}) ...이렇게 적혀있더군요.근데 Github의 소스에는@CreateDateColumn()createdAt: Data;로만 적혀있었습니다. 그리고 @CreatedDateColumn()은 Special Column이라고 아래와 같이 설명이 있던데요.@CreateDateColumn is a special column that is automatically set to the entity's insertion date. You don't need to set this column - it will be automatically set.저는 이 얘기를 TypeOrm에서 자동으로 입력해 주는 값으로 이해했는데... 막상 해보면 안되더라고요.  그래서... 만약 Github의 소스와 같이@CreateDateColumn... 으로 사용하려면 Database에서 Default값을 설정해주어야 하는지(그렇다면 @CreateDateColumn..은 자동 세팅되는 것이 아니겠죠...)아니면 영상 강의 상처럼... default() => "CURRENT_TIMESTAMPT"... 로 사용해야 할지요(물론 영상 강의의 소스는 Database에 그렇게 설정되어 있으니 그렇게 나온것이겠지만요..)

안녕하세요, 강의 잘 듣고 있습니다. 지금까지 발생한 질문들에 대해서 문의드리려 합니다.  Transactional 을 주석처리해도 해당 StockService 와 Repository 인터페이스가 잘 동작하는 모습을 확인할 수 있습니다. (듣다가도 당연히 오류날줄 알았습니다)Data Jpa 를 활요하지 않고 일반적인 Jpa Repository 를 직접 만들어서 (em을 사용하는) 시도를 해봤는데 Transactional 이 없으니 예상했던 오류가 그대로 발생하는 것 같았습니다. JpaRepository 인터페이스에 들어가보니, @NoRepositoryBean 이라는 어노테이션만이 붙어 있고, 그냥 다른 Repo를 만들지 못하도록 달아져 있는 것이라는 것을 확인하였습니다. 작동하는 이유가 Data Jpa 가 제공해주는 Repository interface 를 사용해서 인 것 같은데, 어떤 원리로 작동이 가능한건지 알 수 있을까요? Synchronize 를 사용해도 우선 동작을 하는 이유는 @Transactional 의 동작 방식 때문이라고 설명해주시며, 예시 클래스를 짜서 보여주셨습니다. public void decrease(){ startTransaction(); myStockService.decrease(); endTransaction(); }트랜젝션이란 DB와의 통신을 위해 연결을 짓는 행위로 알고 있는데, DB는 공유 자원인 만큼 당연히 동시성 제어가 되어 있어야 하는 것이 아닌가 생각이 들었습니다. 가령, 위에서 startTx, endTx 를 하는 부분에서 세마포어 처리 등을 해서 교착상태가 발생하지 않도록 설계가 되어 있어야 하지 않나 싶은 생각이 들었는데, @Transactional 에서 그런 것을 처리 하지 않아서 이와 같은 상황이 발생하는게 맞을까요? (강사님한테 문의드리는게 좀 이상한 부분일 수도 있지만, 왜 그런 처리를 안해놨을지 궁금.. 합니다) 감사합니다.

아래 사진과 같은 오류가 출력이 되는데 구글링해도 해결 방법을 잘 못 찾겠습니다 ㅠㅠ 도와주세요!! 

안녕하세요 캡틴판교님 강의를 열심히 듣고있는중입니다.그러던 중, node버전을 미리말씀해주셔서 10.16.3 으로 맞춰서 하고있는데제가 소스분석용으로 받아놓은 소스가 있는데 package.json에 들어가도노드 버전에 대한건 없는거같은데 알아볼수있는 방법이 있을까요??그리고 node버전이 달라도 호환이 되는 정도는 어떻게 알수있을까요??

OAuth2AuthorizationService 구현체를 JdbcOAuth2AuthorizationService로 변경하였습니다.Spring Authorization Server 버전은 1.0 입니다.@Bean public OAuth2AuthorizationService authorizationService(JdbcTemplate jdbcTemplate, RegisteredClientRepository registeredClientRepository) { return new JdbcOAuth2AuthorizationService(jdbcTemplate, registeredClientRepository); }DB Schema : Spring Authorization Server 에서 제공/*

안녕하세요 맛비님.이번 강의를 들으면서 수업 관련 개념을 명확하게 하고자 용어 정리를 하고자 합니다!지금까지 해온 것들을 보면,CNN 연산 모듈을 설계했냐? -> 그렇다. input feature map을 input으로 넣어 output feature map을 도출했냐? -> 아니다. kernel의 size만큼 input feature map에서 window 해서 kernel size의 channel input만큼 해당하는 부분을 Convolution 연산하였다. 최종적으로는 output feature map 1포인트의 channel output만큼 해당하는 값을 구했다. 라고 할 수 있을까요? 처음 듣는 사람이 window라는 말을 잘 이해하지 못한다면 어떻게 쉽게 말할 수 있을까요?
