영상에서 종종 "테스트 하기 좋은 코드는 잘 설계된 코드일 것이다." 라는 말을 해주셨습니다. 어떤 테스트를 기준으로 테스트 하기 좋은 코드가 잘 설계된 코드일까요?- 예를 들어 단위 테스트, 통합 테스트, 인수 테스트가 존재한다 하면, 세가지 테스트 중 어떤 테스트를 테스트하기 편한 코드를 기준으로 잡는게 좋을까요?

제 개인 프로젝트를 진행하면서, 서비스 레이어에서는 단순히, 도메인 레이어에 존재하는 다른 객체들을 호출해서 비즈니스 로직을 처리하는 책임만을 담당하다보니, 서비스 레이어에 존재하는 객체를 테스트하는 코드를 작성하게 되면 대부분 테스트할 내용이, 메소드의 실행순서를 올바르게 실행해줬는가? 와 같은 부분만 테스트할게 없었는데 이 부분이 제가 잘못 설계한 부분이 아닌 오히려, 객체간의 책임을 잘 나누고 서비스 레이어의 책임에 맞게 코드를 작성한것 같다는 확신을 강의를 보고나서 알수 있었습니다 좋은 강의 감사합니다😊

show_pixel_histogram(images_array[0])값이 실행할때마다 항상 다른 히스토그램을 보여주고있습니다.실행할때마다 batch_size만큼 다음 batch로 넘어가기 때문에 히스토그램 값이 달라지는것이 맞는지 여쭤보고 싶습니다.

작업형2 예시문제는X_train과 X_test의 '주구매상품' 컬럼의 카테고리 개수와 종류가 다른 경우였습니다(차집합 소형가전)인코딩 전에 두 데이터를 concat -> 인코딩 후 -> 다시 두 개로 분리하는 것은 원핫 인코딩에만 해당되는 것일까요?왜냐면 라벨 인코딩은 제가 concat 과정을 생략하고 모델 선택 및 예측까지 진행했을 때 딱히 에러가 발생하거나 성능에 문제가 있어보이진 않았습니다. 선생님도 강의에서 라벨 인코딩을 진행하면서 concat 과정을 거치지 않은 걸로 보이고요object형의 카테고리 개수가 다르더라도 라벨 인코딩을 선택한다면 별도의 처리를 거치지 않아도 되는 것인지가 궁금합니다늘 감사드립니다

실전 문제가 pdf로 따로 없는데 혹시 어디에서 볼 수 있나요?미리 풀어보고 난 후에 강의 들으면서 답 맞추고 필기도 하고 싶은데 하나씩 멈추고 풀고 멈추고 풀고 하는게 힘들어서요!

dispose (3분 30초)경부터 제가 의미가 잘 이해가 안되어 문의 드립니다. timer가 null이 아닌것은 항상이라고 봐야겠죠? timer.periodic이 사용되었으니까요?!?  timer.cancel 을 설명하실때 homescreenstate가 삭제되는 순간이 오면이라고 하셨는데... 여기서 왜 삭제되는 순간이 생기는지 모르겠습니다 ㅠ 아직 삭제되기위한 설계전에 미리 설명으로 이해하면 될까요?

구체적으로 :after 를 사용하는 이유는 이미 만들어놓은 item 바로 위에 딱 그 사이즈만큼 쉽게 덮기위해서 인걸까요? :before 가 아닌 :after를 사용한 이유가 궁금합니다.

안녕하세요.강의를 몽땅.. 다 담아서 열심히 수강하고 있는 한 학생입니다.^^학습한 내용을 제대로 이해했는지 확인 하고 싶어 질문 남깁니다. OS도 결국 명령어와 데이터의 조합으로 이루어진 이진수 binary 파일인 프로그램에 불과하며disk에 저장되어 부팅 시 부트 로더에 의해 RAM으로 LOAD 되는 것이며,이 때 커널은 항상 고정 크기를 가지며 파편화가 되지 않습니다.(메모리 가상화를 OS가 해주므로)즉, 커널은 연속된 메모리 공간에 쌓입니다.프로세스들은 이 커널 영역을 공유 사용하며, 저장된 가상 메모리 테이블 등에 의해 맵핑 되구 syscall을 할 수 있습니다.또한 VMWare 등의 프로그램을 통해 가상 머신을 돌릴 때도 커널은 고정 크기를 가집니다.VM에서 실행할 때, RAM 용량 설정, Thread 갯수 설정 등의 옵션이 있는데4코어 8GB 환경이라면 VM에 2코어 4GB를 지정해주면이를 딱 조절해서 HOST와 Virtual OS는 자원을 반 씩 나눠 쓰는 개념이기 때문이고, 가상 OS 상에서의 프로세스들은 Virtual OS에 의해 가상 메모리를 관리 받습니다.검색과 고민 끝에 이렇게 이해를 했는데 잘 한 것이 맞는지,잘못된 부분이나 조언해주실 것이 있다면 부탁드리겠습니다.^^항상 잘 듣고 있습니다.감사합니다. 

히스토그램이랑 describe로 확인한 price 값 중에 굉장히 멀리떨어져있는 값이 나왔는데, 이건 이상치로 해석하는게 아닌가요?'그리고 강의에서 r 2값이 0.077이 나왔는데. 이게 평가 지표에서 좋게 받을 수 있는건가요?R에서는 상관관계랑 *** 로 변수를 선택하는게 있었던거 같은데, 파이썬에서는 그냥 진행해야하는건가요?
