안녕하세요.감사합니다. 수업 재미있게 듣고 있습니다. 사용하시는 IDE 환경에 대해서 궁금한 점이 있습니다.강의중에 보니 Visual Studio 에서 아래와 같이 코드를 추천해 주는 확장을 사용하고 계신 것으로 보입니다.확장 기능의 이름이 궁금합니다.저는 vscode 에서 실습중이긴 합니다만 비슷한 확장이 있는지 찾아보려 합니다. 그 밖에 vscode 에서든 Visual Studio 에서든 강사님께서 추천해 주실 만한 확장이 있을까요?

[그림 1] (Label) 강의 화면, 유틸리티 탭(우측 하단) 활성화[그림 2] 학습자 화면Xcode UI가 달라서, 학습 진행이 어렵습니다. 구체적으로 유틸리티 탭에서 Label 기능을 이용하고 싶은데, 유틸리티 탭이랑 아이콘 뷰 자체가 없어서, 어떻게 해야 할 지 잘 모르겠습니다. 유틸리티 탭 같은 예전 기능들(?)은 어디에서 확인할 수 있을까요? 일단 커뮤 찾아봤는데, 없어서 질문 올립니다.

A* 알고리즘으로 탐색한 결과가 진짜 최단거리가 아닌 경우도 존재하나요?

안녕하세요, 올해 시험을 준비중입니다. 최근 실기 문제출제유형이 변경된다고 공지가 떴네요. 실기 단답형이 없어지고, 실습형으로 대체된다고 합니다. 강의 내용에 보완해 주시면 좋을 것 같아요.

프로세스간 연결시 왜 ip를 통해서 가나요?(그러니까 소켓열어서 파일 입출력하는 이유가 무엇인가요)그냥 memory를 공유할 수 잇는 방법이 잇으면 더 빠를거같은데보조기억 장치 메모리를 공유할 수 잇는 방법이 어렵거나 불가해서 저렇게하는건가요?

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예/아니오)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오)[질문 내용]여기에 질문 내용을 남겨주세요.이렇게 생성자의 매개변수에 빨간줄이 뜹니다.실행을 시켜보면 실행이 되긴 합니다.org.h2.jdbc.JdbcSQLInvalidAuthorizationSpecException: Wrong user name or password [28000-214] at

안녕하세요. 선생님 토큰을 이용해서 디자인 시스템의 컴포넌트들을 프라이머리와 세컨더리 컬러로 정의된 스타일로 만들었습니다. 이후에 토큰을 익스포트해서 저장한 Json 파일을 새로운 디자인 파일에 import해서 로컬 스타일에 등록해주주고, 퍼블리시한 디자인 시스템 파일의 라이브러리를 이용해 새로운 디자인 파일에서 디자인을 하려고 하는합니다.그런데 컴포넌트의 등록한(디자인 시스템의 라이브러리에 등록된 컬러들로 만들어 진 컴포넌트)이 새로운 파일에서 테마를 변경해도 변화가 없습니다.대신에 로컬 스타일의 컬러를 입혀주니까 테마 변경이 가능했습니다. 여기서 궁금한점은 디자인 시스템에서 만든 모든 컴포넌트들에 로컬 컬러를 입혀줘야 테마 변경이 가능한지요? 아니면 제가 뭘 놓치고 있는건지 궁금 합니다ㅜㅜ 감사합니다ㅜㅜ

아래 코드도 잘 짠게 맞을까요? function solution(require, direct) { let answer; let queue = ""; for (let i = 0; i < direct.length; i++) { if (require.includes(direct[i])) queue += direct[i]; } if (queue === require) answer = "YES"; else answer = "NO"; return answer; }

스프링 빈이 등록될 때, @Bean으로 지정하거나 @Component로 지정한 객체 자체가 빈으로 등록 되는 건가요 아니면 이러한 어노테이션으로 지정한 '객체를 생성하는' 객체가 빈으로 등록되는 건가요?

위 캡처처럼 Total Recovered가 0으로 나옵니다.네트워크 패널에서 확인해보니 TotalRecovered 값이 다 0으로 들어옵니다.이거는 api의 문제인건가요?

선생님께서 유튜브에 올리신거같은데 인프런에서는 어느강의 인지 몰라서 여기부분에다 올립니다.https://www.youtube.com/watch?v=mzLx_NWpuSY8분 42초에는 (a*a*a)%c하게 되면 a값이 2억일때 longlong에서도 범위가 넘어가서 (a%c*a%c*a%c)를 하셔야 된다고 했는데 9분9초에서 코드를 보니까 ret=(ret*ret)%c 가 적혀있는데요. (ret*ret)%c부분에서 (ret%c*ret%c)이렇게 해야 하는거 아닌가요? 그리고 10번줄에 if(2)도 true인데 if(1)홀수일떄만 작동된다고 하셨는데 짝수일떄도 작동되는거 아닌가요?

강사님 언제나 양질의 강의에 감사드립니다. 강의 덕분에 1회독을 수월하게 끝낼 수 있었습니다.다름이 아니라 텐서플로우의 GRU셀의 파라미터 개수에 대해 질문이 있습니다.538p의 GRU 방식에서는 Wg 뉴런에서 Wh, Wx를 한번에 처리하여 절편이 해당 뉴런에 하나 배정되었던 것으로 이해했습니다. 이전에도 파라미터의 개수를 계산할 때 절편은 뉴런당 하나이므로...의 방식으로 제일 마지막에 절편 개수를 더해왔구요.그런데 540p에서 Wh와 Wx를 계산하는 순서가 분리되어 개별적인 절편이 필요하다는 부분이 조금 이해가 되질 않습니다. 해당 부분을 '별도의 선형 방정식이 추가 된 것'이라고 설명 해주셨는데 추가적인 셀이 생성 된 것은 아니겠지요...?여태 제가 이해한 것이 '뉴런 당 절편 하나' 이어서 그런지 '별도의 선형 방정식이 추가 된 것'이라는 설명이 직관적으로 이해되질 않습니다... 실제로 538p의 Wg셀은 그대로이고 내부적으로 방정식과 별도의 절편만 추가 된 것으로 이해하면 될지, 아니면 Wh라는 별도의 셀이 추가 된 것으로 이해하면 될 지 궁금합니다
