안녕하세요 6번 파일은 사운드가 포함되어 있어 배치하면 기존의 사운드가 잘립니다. 이건 어떻게 해야 할까요? 버전은 2020 입니다

강의 따라하면서 재밌게 잘 듣고 있습니다. loop함수만 켜면 강아지 레이어가 스크롤 하자마자 번개같이 위로 올라가서 (...) 아직 혼자 보고 고치기엔 무리라  js 완성본을 받고 싶습니다. cheryleduart@gmail.com 으로 완성파일 보내주시면 감사하겠습니다.

localhost/dvwa라고 치니깐 로그인 창이 나와요

안녕하세요! 강의 정말 잘 듣고 있습니다~ 항상 감사합니다. 다름이 아니라, 로그인, 회원가입을 구현하던 중에 궁금증이 생겨 질문드립니다. 로그인이나 회원가입시 form을 통해 비밀번호를 서버로 보내면 request body에 비밀번호가 노출되어 전달되는데요, 이렇게 되면 보안상 위험이 있는것 아닌가 해서 숨길 수 있는 방법 혹은 암호화 해서 보낼 수 있는 방법이 있는지 문의 드립니다! 감사합니다.

안녕하세요 강사님 질 좋은 강의 항상 감사드립니다. 다름이 아니라 해당 강의의 7분 이후부터 실행의 오류가 떠서  제 나름대로 이전에 쓰던 Member 클래스를 삭제하지 않고 그대로 써서 있는 오류라 생각하고 import 해당 부분을 삭제 하고 다시 실행을 해보니 화면과 같이 몇 시간째 계속 구동만 하고 있습니다 ㅠㅠ  혹시 어떤 부분에서 이상이 생긴건지 알고 싶습니다. H2 데이터베이스도 다시 껐다 켜보니 테이블의 속성들과 엔티티들이 제대로 생성 되었으나 프로젝트가 제대로 실행이 안되네요.. 오전 4:23:06: Executing task 'JpashopApplication.main()'... Starting Gradle Daemon...

2. 사라집니다. 질문의 의도를 추측해보자면 take은 한 번 실행하고 더이상 실행이 안되는데 delay랑 Put은 왜 다음번에 되는지를 물어보시는 것 같은데요. watch 함수는 한 번만 실행되고 login* 함수같은 것은 매번 실행돼서 그렇습니다. 하나의 함수 안에서 더이상 호출이 안 되는거지 새로운 함수가 또 실행되면 새 함수 안에서는 실행됩니다. ============================================= 밑에 다른 분께서 올리신 질문중에 take와 다른 이펙트들에 대해서 질문한 글을 봤습니다. 저도 궁금한 점이 있어서요. watch 함수는 한 번만 실행하고 login* 함수는 매번 실행한다는 게 어떤 의미 일까요? 만약 로그인을 한다고 하였을때  watchLogin() --> Login() --> loginAPI() .. 1) 이런식으로 불리는데 어차피 take든 delay든 put이든 다 한 번만 불려서 한 번만 쓰고 버려지는 그런게 아닐까요? 2) 사실 한 번만 실행이 가능하다는건 이해를 했는데 그 의도가 이해가 안가네요. 그냥 take라는 이펙트 자체의 의도가 한 번만 실행하도록 한거고 여러번 눌릴것을 대비하여 takeLatest를 쓰면된다라고만 이해하면 될까요? 3) 그리고 take가 단 한번만 실행이 가능하다는 의미가 한 번 실행후에는 함수를 불러도 더 이상 실행이 안된다. 그러나 delay나 put같은경우에는 같은 함수를 실행하면 다시 실행된다. 이렇게 이해를 해야할까요. 감사합니다.

안녕하세요 ! 기존에 배열을 정렬할 때, 화살표 함수를 사용하다가 곧장 arr1.sort()를 하니 어색해서요 ! arr1 = [1,3,9,5,2]라는 배열이 있을 때, arr1.sort((a,b) => a-b);하는것과 arr1.sort().reverse(); 하는 것은 코딩 스타일의 차이인가요?

안녕하세요 ! 커뮤니티에 게시글을 보다가 '' 이 문제의 해법은 sort를 피하겠다는 것이 아니라 2중 for문 즉 시간복잡도 O(n^2)를 피하겠다는 뜻입니다. 참고로 sort의 시간복잡도는 O(nlogn)입니다.   '' 이런 답변을 봤어요~ 구글에 시간복잡도에 대해서 검색해봐도 다 이런 수학 기호들이 난무하는데요..! 어떻게 쉽게 이해하면 좋을까요..? 저는 function solution(arr1, arr2) { let answer = []; for(let x of arr1) { for(let i = 0; i < arr2.length; i++) { if(x === arr2[i]) answer.push(x); } } answer.sort((a, b) => a - b); return answer; 이렇게 풀었는데 투 포인터로 푸는 방식보다 많이 느린가요?? 더 빠르다, 느리다의 기준을 모르겠습니다 ㅠㅠ

안녕하세요 루키스님 회전행렬의 값에 대해 질문드립니다. z축회전변환 행렬을 구할때 X= xcosθ -ysinθ이며 Y= xsinθ + ycosθ 라고 하셨습니다. 그렇다면 m12 = sinθ이며 m21= -sinθ여야하는게 아닌가요? 찾아봤을때도 어디서는 그렇게 나오고 다른곳은 루키스님이 말씀하신것처럼 나와 헷갈려 어떤 차이가 있는지 질문드립니다. 고맙습니다.
