안녕하세요! 강의 이제 막 보기 시작했어요! :)그런데 강의에서 알려주신 것처럼 피그마 토큰 플러그인에서 green.500을 등록한 후 create style을 하면 (첫번째 사진),2,3번째 사진처럼 피그마 오른쪽 패널에 green.500 뿐만 아니라 엄청 많은(?) 컬러들이 등록되어서요!어떻게 하면 green.500만 등록시킬 수 있을까요?! +) 그리고 저는 플러그인을 실행하면 강의에서와는다르게 아래 사진처럼 보입니다..!!!

안녕하세요. 처음 msa를 접하고 구성 관련해서 공부 중 궁금한 게 있어 문의드립니다.msa를 구성한다고 할 때 프론트엔드 <->APIGateway <-> 백엔드 <-> DB 이 흐름이 기본이라고 봐야 하나요?이렇게 구성하고 외부로 노출되는 도메인이 프론트엔드, APIGateway 이렇게 두 개가 되는걸가요?여기에 ISTIO까지 추가된다면 ISTIO GATEWAY <-> 프론트엔드 <-> APIGateway <-> 백엔드 <-> DB이런 구조로 구성해서 도메인을 ISTIO GATEWAY만 가지고 ISTIO GATEWAY가 프론트엔드와 APIGateway로 라우팅하는 식으로 구성하는게 맞을까요? 아니면 APIGatway를 가장 앞에 두고 APIGateway를 통해서만 프론트엔드와 백엔드를 호출하는 방법은 잘못 구성한거라고 봐야할까요?아래처럼 구성하니 프론트엔드에서 css, image들을 불러올 때마다 APIGateway를 타고 가야해서 이 방법이 맞는 건가 싶습니다.APIGateway <-> 프론트엔드 <-> 백엔드 <-> DB  

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! 안녕하세요. 우선 머신러닝에 대해 알기쉽게 강의해 주셔서 감사합니다.저는 기계의 고장진단 및 예측을 위해서 머신러닝을 공부하고 있는 직장인 입니다.다름이아니라, 실습에서 다루는 데이터는 다양한 정보들이 1개의 파일에 있어, 학습 및 테스트를 진행하였습니다. 그러나, 전압,진동과 같이 물리적 데이터는 일정시간 동안 데이터를 계측하게 되고, 이러한 파일이 여러게 존재하게 됩니다.(첨부된 그림 참조)이렇게 데이터 취득시, 현실적으로는 고장데이터를 취득한 파일 전체의 레이블이 1(1이 고장이라 하면), 정상상태를 취득한 파일은 0이 되어야 합니다.이렇듯 다수의 파일, 1개의 파일 안에 시간순으로 측정된 다수의 데이터가 있을 경우, 학습 및 테스트를 하기위한 데이터 전처리 방법이 궁금합니다.수고하세요.

Ratinanet의 FPN 강의를 듣고 있었습니다. 각 구간별 피처맵에서 UPSapleing하여 더해준 후 3X3 covolution 연산을 해준다고 들었는데 그 후 3X3 convolution 연산을 하는 이유가 에어리얼 스페이싱 때문이라는 거 같은데 이게 맞는건지 여쭙고 싶습니다.

webview 강의 진행중입니다.그냥 진행할까요? 그냥 돌아가서 진행했습니다.결과는 나왔네요. 빨강색 에러는 뭔가요

vector<int> v; vector 메모리를 까보니까 힙영역인거같은대 맞나요?  

 안녕하세요 맛비님.다른 프로젝트에서 gui모드로 protocol instance를 웨이브폼에 추가 해보려고하는데. protocol instance를 못찾는 것 같아요. 빌드파일에는 따로 옵션을 넣어주셨던데.. gui에서는 따로 설정하는 법이 있나요?

 http://boj.kr/2711088b44d64f2ca315c5f8d4e2f5c8  이런 코드로 작성해도 효율적인가요?

포켓몬스터 이다솜은 1165에서 1620으로 변경된 거 같아요

iocp 를 설명하는 부분에서 메인 쓰레드에서 CreateIoCompletionPort 함수로 cp 에 소켓을 넣고 WSARecv 를 해주면 그 다음부터는 다른 쓰레드에서 WSARecv를 해줘야 한다고 하셨는데 그렇다면 그 소켓은 cp 에 게속 있으면서 이벤트를 받는건가요?

마지막에 setContent("")로 해주는 이유가 있을까요?

똑같은 버전 설치하고, 코딩을 따라서 입력했는데 BrowserRouter을 사용한 후로 크롭에서 실행되지 않습니다.해결방법이 있을까요? 

강의에서는 네이버 -> 쇼핑 버튼 클릭 시 현재 창이 네이버 쇼핑으로 전환되어 예제가 정상 동작하고 있었습니다.현재 시점에서 네이버 -> 쇼핑 버튼 클릭 시 새 탭이 생기면서 문제가 발생하고 있었습니다.https://www.naver.com 이 실행되어있는 첫번째 탭에서 두번째 탭에 있는(네이버 쇼핑) input type text에 해당하는 selector를 검색하고 있으니 어떤 동작도 하지 않는 것으로 보이는 것 같습니다.해당 소스 내에서 활성화된 탭을 마지막 탭으로 이동시키는 소스를 집어넣으면 나머지 뒷 부분이 정상적으로 동작하는 것 같습니다.강의 들으시는 분들은 참고하시면 좋을 것 같습니다.

스크립트 설명 강의에서 Start와 awake 함수의 차이점이 궁금합니다.
