강사님 안녕하세요! plan 섹션을 반응형으로 만드는 과정에서 추가적으로 궁금한 점이 있습니다! history에 div들이 모바일로 바뀌면서 한개씩 슬라이딩하는 형태로 되었는데요. 제가 디자이너로 일할때 이부분 div가 오른쪽에 빼꼼~ 하고 보이는 형태(위 이미지처럼요)가 UX적으로 좋아서 이대로 퍼블에 넘기면 똑같이 해줬었거든요...! 근데 제가 해보려고 혼자서 개발자도구를 열어봤는데  이렇게 클래스 안에 style로 걸려있더라구요. 제가 학원에서(입문정도로만 배워봤습니다) 강사님이 이렇게 클래스에 스타일이 있는건 자바스크립트로 스타일을 준 경우라고 하신 기억이 났습니다. 그래서 slick.min.js에서 이 부분을 찾아서 width를 고쳐보려고 했는데 어떻게 찾아야 할지 모르겠습니다. min으로 되어있어서 보기가 어렵네요!  그래서 responsive.css에 적어서 덮어씌우려고 했는데 이렇게 먹혀버립니다... 어떻게 해야 할까요?

안녕하세요 강사님. 원본데이터에는 공백이 하나인데, split 할때 공백울 2개씩 넣어줘야하는 이유가 있나요? 원본 데이터 '18.17배 l 3,549원' df_pe["PER"] = df_pe['value'].str.split(' l ',expand=True)[0] 제가 복사해서 텍스트 에디터에서 확인하면 공백이 하나입니다. 혹시 복사해서 보면 다르게 보이는건가요? 여기서 공백을 하나만 넣어도 분리는 되지만 다음 결측치 제거에서 공백때문에 공백처리를 한번더 해야합니다.

웹 프론트엔드가 사용자와 상호작용하는 부분이고 웹 백엔드가 네트워크의 응용 프로토콜로 통신하는걸 지원하는거라면 아이피xxx가 할당된 동일한 서버컴퓨터에 웹 프론트와 백엔드가 같이 배포가 되는건가요??? 그리고 사용자 단말기에 설치된 웹 브라우저와 서버컴에 배포되어있는 웹 프론트 코드랑은 어떤 관계가 있나요???

안녕하세요, 선생님! 강의 듣던 중 궁금한 점이 있어서 질문 남깁니다. 원래 텍스트 쓸 때 기본적인 높이값이 있는것 같은데 제가 예제실습 따라하다가 무언가 잘못 설정을 한건지 폰트 크기를 조절해도 폰트 크기 24일때 높이값이 그대로 고정되는데 어떻게 해결해야할까요? - ↑오토레이아웃을 한게 아닌데 위아래로 패딩 먹인 것처럼 간격이 생겨요ㅠ - 이건 다른 파일에서 텍스트 써 본 것입니다. 둘다 폰트는 roboto 체입니다.

이미지 1장 올릴 때는 잘 되는데 2장을 한번에 업로드 할 때 original 폴더에는 올라가는데 thumb 폴더에는 안올라가네요 리사이징이 안되는 부분인거죠? 람다 index.js에서 수정을 해야할까요?

안녕하세요! 9분 30 에 나오는  first_doc =True의 의미를 모르겠습니다... 뒤에 조건문에서도 쓰이는 의미를 파악 못하겠는데  True가 갖는 효력이 있는건가요? 아니면 다른 것으로 대체할 수도 있는건가요?

안녕하세요 ㅎㅎ 세션과 소켓에 이 정확히 무엇인지 이해가 잘 안돼서 질문드립니다. 제가 이해한걸 정리하면 소캣은 서버와 클라가 통신할 수 있는 수단 혹은 통로라고 생각합니다. 그렇다면 세션은 무엇인가요? 소캣을 포함하며 구조적으로 설계가 잘 된 사용자 정의 인터페이스라고 봐도 되는건가요?

안녕 하세요 좋은 강의 듣고 있습니다. 문의 사항이 있습니다 학습시간을 줄이기 위해서 다음과 같이 하고 있습니다. 1. GPU 3xxx 구입하여 줄림 2.서버를 임대하여 줄임 위의 두 가지 방법은 전부다 이해가 되었는데 만약 1000장을 학습하고 나서  200장을 학습하려고 하면 기존 방법은 1200장을 다시 학습 하였습니다. 200장만 학습하여 시간을 단축 시키는 방법은 없을까요? 답변 부탁 드립니다.

Batch fetch size 가 어떻게 적용되는지 블랙박스인 느낌이 드네요. 관련된 원리를 알 수 있을까요?  stream().map 을 통해서 루프를  돌면서 Lazy Loading을 할 텐데 각 루프를 실행 할 때 쿼리를 날리지않고  다돌고난후 알아서 in 절에 채워넣어주는건 Hibernate가 알아서 해주는 건가요? 어떻게 가능한지 감이 안오네요

이번 강의에서 사용한 return code || ''   || 를 좀 찾아보니  A || 'ABC'   이런식으로 적으면 A값이 없을때 ABC 가 출력된다고 나와서요. 이번예제에서는 code에 0값이 있어도 값이없다고 인식하는건가요?? 또 && 을 사용하는 조건문 좀더 자세하게 설명해주실수 있으신가요?
