선생님께서 2차원 체크 배열 만드실때 항상 ch=[[0] *n for _ in range(n)]   과 같이 만드시는데,   왜 ch=[[0]*n]*n 으로 만들면 안될까요     예를 들어 n이 3일때   ch=[[0] *3 for _ in range(3)] print(ch) => [[0, 0, 0], [0, 0, 0], [0, 0, 0]]   ch2=[[0]*3]*3 print(ch2) => [[0, 0, 0], [0, 0, 0], [0, 0, 0]]   print값은 둘다 동일한데     ch[0][2]=1   ch2[0][2]=1   을 넣으면     print(ch) =>[[0,0,1],[0,0,0],[0,0,0]]   ch2=[[0]*3]*3 print(ch2) =>[[0,0,1],[0,0,1],[0,0,1]]     이렇게 결과가도출되네요..   어떻게 다른지 알려주세요 ㅠㅠ

  1) 가로 네비게이션에서 서브메뉴 a태그 갯수로 인해 이렇게 되는 부분은 어떻게 해결하면 좋을까요? 저부분에 border가 없습니다.       2) .btn span에 margin-bottom:-5px; 이라 입력했는데 위의 이미지처럼 span보다 아래 보더가 위로 올라오는데, 뭐가 잘못된걸까요? 다시 검토해보아도 잘못된 부분을 못찾겠습니다  

55초 '플러시 발생' 관련 문의 드립니다.   기존 강의 슬라이드에 그려지고 설명된 바로는, persist()호출 되거나 영속 상태의 entity에 변경이 발생할 때, 영속성컨텍스트 1차 캐시 Entity가 업데이트 되고 동시에 지연 SQL 저장소에 추가된다고 설명해 주셨습니다. 즉, flush() 호출 시에는 단순히 이미 저장 된 batch SQL들을 Query하고 DB transaction을 commit한 뒤 1차 캐시 스냅샷을 업데이트할 거라 예상했습니다.   그런데 이번 강의에서는 em.flush() '호출 시'에 '변경 감지' 및 '수정된 엔티티 쓰기 지연 SQL 저장소에 등록'을 수행한다고 설명해 주셨네요.. 타이밍에 대한 설명이 상이한데, 어느 쪽이 맞는 설명인지 문의 드립니다..

강의를 듣다가 궁금한 부분이 생겨서 질문합니다!   float deltaTime = 0;         void ExplodeAfter4Secod()         {             deltaTime += Time.deltaTime;             if(deltaTime >= 4)             {                 // 로직             } 이렇게 코드를 작성하여 실행을 시키면 컴퓨터가 매프레임마다 deltaTime에 Time.deltaTime을 더해서 if문으로 확인을하고 다시 시간을 더해서 if문으로 확인을하고  이러한 일련의 작업들이 무식하고 비효율적이다 => 그래서 시간 매니저를 만들어서 시간매니저에게 "4초후에 무엇인가를 하고싶어!"라고 던져주면 시간매니저가 4초가되었을때 알려주어 해당 로직을 실행하게하면, 매프레임마다 매프레임마다 시간을 더해서 if문 체크를 하는 낭비를 생략할 수 있다.  즉, 중앙에서 관리를 하면 낭비를 줄일 수 있다라고 설명을 하셨는데   1. "4초후에 무엇인가를 하고싶어!"라고 시간매니저(중앙)에 던져주어 매니저가 시간을 샌다음에 결국에 다시 해당 함수에 "4초가 지났다!"라고 알려주어 해당함수의 로직이 실행이되는것같은데.. 매니저에게 "4초후에 무엇인가를 하고싶어!" 라고 던져주면 결국 매니저도 연산을 한뒤에 요청을 보낸 함수에게 알려주는 것이니까 결국 같은것아닌가용...??ㅎㅎ;;(원리가 잘 이해가 가지 않습니다)   2. 시간 매니저에게 "4초후에 무엇인가를 하고싶어!"라고 보냈을때는 매틱마다(매 프레임마다)연산을 하지않고 4초가지났다라고 해당함수에게 알려 줄 수 있는것인가요??   3. 시간매니저에게 "4초후에 무엇인가를 하고싶어!"라는 요청을 보낼때 매프레임마다 연산을 하지않는다면 시간을 어떻게 재서 다시 해당함수에게 알려 줄 수 있는것인가요??   4. 코루틴이 1~3경우에 굉장히 유용하다고 설명하셨는데 코루틴은 어떠한 원리로 "4초를 일시정지"햇다가 다시 실행시켜 줄 수 있는것인가요?  일시정지를 했더라도 일시정지한 시간을 알아야 4초후에 알려줄 수 있는거같은데...일시정지하는동안도 연산을 하나요??

현재 상황은 로컬pc와 aws ec2 인스턴스를 site to site vpn방식으로 연결하고, 로컬 pc를 마스터노드, ec2 인스턴스를 워커노드 형태로 쿠버네티스 클러스터를 구성한 상태입니다. 같이 하는 친구가 워낙 잘 해서 이렇게 인프라를 잘 구축해줬는데, 저는 여기서 스토리지 클래스를 구성해 동적 프로비저닝을 구현하면 좋겠다는 생각을 해서 쿠버네티스 문서에 나와 있는 내용과 강의시간에 배운 내용들을 참조해 로컬 마스터노드에서 작업을 진행중인데 생각보다 구성이 잘 안 돼서 질문드리게 됐습니다.  로컬 마스터노드에서 스토리지클래스를 구성해 쿠버네티스 클러스터로 연결된 ec2 인스턴스의 ebs를 프로비저너로 사용하려고 하는데 이게 구현이 가능한 기술일까요? 계속 찾아보니 aws에서 제공해주는 aws storagegateway와 s3를 이용한 datasync가 있는데 꼭 이 방법을 이용해야 하는지 아니면 ec2와 연결된 ebs에 볼륨을 붙일 수 있을지 궁금해서 질문드립니다. 질문 드리기 전에 여기저기 찾아봐도 nfs를 이용한 스토리지클래스들의 예는 조금 찾아볼 수 있는데, 이 경우 마땅한 레퍼런스를 잘 찾을 수 없어 염치 불고하고 질문드립니다.

제가 아직 실무코드를 많이 못봐서그런데 장고나 flask는 보통 타입힌트가 없는데, fastapi는 타입힌트를 적극적으로 쓰는 것같더라구요. 장고나 flask에서도 타입힌트 자주 쓰이나요?

안녕하세요, 틈틈히 유익한 강의 잘 보고 있습니다.스위치가 MAC소를 기반으로 Frame을 전달 하는 장치라고 배웠습니다. 그러면 이러한 스위치에서 맥 테이블 조회를 하여 각각의 스위치 포트들이 아래의 두가지 사항을 찾을 수 있는지 질문드립니다.  1. 각 포트들이 어디에 연결되어 있는지 알 수 있는지 2. 업링크 포트는 따로 표시 되는지(안된다면 기본적인 규칙이 있는지) 위의 두개 항목이 궁굼합니다..    

Youth와 같은 포맷으로 Old 테이블을 만든 후 새로고침을 누르니 old chart가 생겨났는데요. 만약 저 데이터가 로컬에 저장된 데이터라면 당연히 - 데이터 변환을 통해서 이전 데이터셋을 전부 들어내고 새롭게 넣어줘야 하겠죠?  현 회사에서 원드라이브를 사용하는데 원드라이브와 연동시켜서 해야할까요? DB 는 없고 원드라이브에 월별 폴더를 만든 후 매번 들어가서 업데이트 하는 형식입니다.   

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.   강의 도중에 최상단은 verilog 파일이여야 한다며 design_1_wrapper를 만드시는 데요 이렇게 하는 이유가 무엇인가요? (Create Block Design으로 생성된 input output 포트를 연결하기 위해서 인가요?)

노드의 리소스가 부족하여 파드 배포가 안되었을때 노드의 리소스를 확보하고 다시 파드를 배포해도 여전히 pending 상태더라고요 노드의 리소스가 많이 남아도 계속 pending 상태인데 혹시 이런경우 노드에 자동으로 no schdule나 테인트가 걸리나요?? 결국 디플로이먼트 yaml의 리소스 request 부분을 지우니깐 다시 running 상태가 되긴 하는데 왜 그런지 궁금합니다   요약: 노드의 리소스가 부족하여 파드 running이 안되어 리소스를 확보하고 다시 배포했는데 계속 pending 상태입니다. 

안녕하세요 저번에 tflite로 변환하는 과정을 질문한 학생입니다. 저번에 선생님께서 yolo보단 eiffcientDet를 사용해보라고 하셔서 모델을 변경하여 train했습니다. 해서 antoml의 git에 따르면 tflite로 변환하는 기능이 있어 사용하였는데 이와같은 에러가 나와서 문의 드립니다. batch_size문제로 확인되는데 어느부분이 문제인지 감이 안오네요...

안녕하세요   toString.call()을 이용하여 타입을 확인할 수 있다고 했는데, 언제 사용하나요 ??   typeof()와 비교했을 때, 차이점이 무엇인가요?

안녕하세요.   taskExcecutor 지정해서 muti 쓰레드로 실행시 어플리케이션 종료되지 않는데 이건 taskExecutor 내부적으로 뭔가가 떠있어서 그런건가요?   taskExcecutor 지정 안했을 때는 정상 종료됩니다.

안녕하세요 메일 소식받고 코멘트 남깁니다~!    강좌 수강할 의향 있습니다!

하루전까지 잘 되었는데 갑자기 이런 오류가 떴습니다. JpashopApplication에서 실행했을때 오류 전문입니다. "C:\Program Files\Java\jdk-11.0.9\bin\java.exe" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2020.3\lib\idea_rt.jar=56326:C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2020.3\bin" -Dfile.encoding=UTF-8 jpabook.jpashop.JpashopApplication Error: Could not find or load main class jpabook.jpashop.JpashopApplication Caused by: java.lang.ClassNotFoundException: jpabook.jpashop.JpashopApplication   Process finished with exit code 1 ---------------------------------------------------   이런 경우 어떤 식으로 디버깅을 해야하는지 궁금합니다.
