안녕하세요. 강의에서 일반문과 그것의 축약문의 어셈블리 비교를 통해 효율성을 체크했습니다.그냥 보면 둘은 똑같아 보였는데, 자세히 보니 끝에서 두 자리가 다르더군요.이건 제 단계에서 크게 신경쓰지 않아도 되는 것 같은데, 그래도 궁금해서 질문드립니다.일반문과 축약문의 어셈블리가 완전 같지는 않은데, 저 정도는 효율성을 따지는데 있어 굳이 신경 쓰지 않아도 되는 건가요?

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 예3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]여기에 질문 내용을 남겨주세요.new-form.jsp는 잘 접속이 되는데전송을 누르면 아래와 같이 오류가 발생합니다."C:\Program

하드코딩으로 값을 넣었을때는 잘진행이 되었는데요ㅠㅠ 안에 값을 지정하니 에러가 계속뜨네요 아마 이 부분 에서 고쳐야 할 점이 있는 것 같은데 똑같이 작성을 한 것 같음에도 동작이 안되서 질문드려봅니다

sumArray 함수에서 return 값인sumArray(arr.slice(0, -1)) + arr[arr.length - 1] 구문이 이해가 잘 안되는데arr.slice(0, -1) 은 [1, 2, 3, 4]이고arr[arr.length - 1]은 5인데[1, 2, 3, 4] + 5 값으로는 1, 2, 3, 4, 55 나와야 되는게 아닌가요??어째서 sumArray([1, 2, 3, 4])를 줬다고 해서1 + 2 + 3 + 4 가 되는 지 모르겠습니다.만약 그렇게 되려면 아래 같은 로직이라고 있어야되는거 아닌가요?? let plus = 0; arr.forEach(el => { plus += el });도저히 이해가 안되네요 도와주시면 감사하겠습니다!!

 안녕하세요. 주피터 노트북 관련해서 궁금한 점이 있는데요, 제가 처음에 지정해놓은 경로에 파일을 두고, 주피터 노트북 실행해서 작업을 하닥, 주피터 노트북 경로 파일 폴더를 열어보니,아래와 같이 .ipynb_checkpoints라는 폴더가 만들어져있더라구요.해당 폴더 안에 들어가보면 원래의 파일들이 해당 폴더 안에 또 만들어져있는데, 이거는 자동으로 백업해주는 기능인가요?

기존에 있던 강의랑 겹치는게 있고 안겹치는게 있는거 같은데 이 강의를 듣고 다음 강의는 어떤걸 들어야 할까요?

문제도 이해안가고 풀이도 이해안가면 포기하는게 맞을까요? ㅜㅜ그냥 어거지라도 보고있는데 이해가안가요,,,첫번재영화 1666 두번째 2666이면10번째는 10666 이런식 아닌가요?? 풀이를 봐도 문제가 답을 뭘 원하는건지도 모르겠어요,,너무답답해요커뮤니티 보니까 저만 이런것 같고,,

동시에 여러명이 요청하는 케이스를 카프카로 해결하는 케이스에서 테스트를 실행하였더니 카프카 컨슈머에 아무런 메시지가 전달되지 않아 질문드립니다. 토픽명은 강의와 다르게 "coupon"으로 생성하였습니다.

선생님 안녕하세요! 가설을 세우고 (예를 들어 이 서비스의 이 기능을 많이 사용할 것이다.), 이에 대한 검증에 필요한 방법이 사용자 리서치라고 하셨는데요. 혹여나 해당 기능이 실제로 많이 안쓰인다면, 즉 가설을 잘못 정해서 검증에 실패했다면 어떻게 하나요? 이런 경우 디자이너의 신뢰도도 떨어질 것 같아 왠지 좀 두려운(?) 부분인 것 같습니다. 현업에서 이러한 사례가 있었는지도 궁금합니다!

구글 계정으로 회원가입한 후 강의를 구매했습니다.구글 소셜 연동을 해제하고 싶어서, 고객센터에 나와있는대로 연동을 해제했는데,구매한 모든 강의가 사라졌네요 ㅠㅠ해결 방법 아시는 분 계실까요?

Vitis에서 더미파일을 만든 후 FPGA에 비트스트림을 올렸는데, Vivado에서 비트스트림 만들고 바로 올리지 않고 굳이 vitis에서 올렸던 특별한 이유가 있나요?!처음에는 PS에서 공급하는 CLK 주기를 조작하기 위해서라고 생각했는데, 생각해보니 vivado에서 block design 할 때 clk 주기를 이미 줬더라구요..! 궁금합니다 PL영역 안에서 (PS와의 연결 없이) 사용하는 clk의 기본 클락 주파수가 있을텐데, (아마 100Mhz였나요..) 이를 PS와의 연결 없이 조절할 수는 없는건가요?!감사합니다 :)
