안녕하세요 강사님, 강의 잘 보고 있습니다. 5강에서 info.json파일을 getResourceAsStream로 찾아서, inputStream으로 가져오는 부분이 계속 에러가 나서요.. 뭐가 문제인지 애매합니다. debug찍어보니 NullPointer에서 문제가 있다고 나오긴 하는데, File도 강의 상에 있는 경로로 만들었고 다른걸로 메서드 import를 다른걸로 입력시킨 것도 아닌데.. 뭐가 문젠지 잘 모르겠네요.. 혹시몰라, 코딩 내용과 폴더 구조 올립니다.. 답변 부탁드립니다.. ㅠㅠ

좋은 강의, 친절한 답변 너무 감사드립니다! 다름이 아니라, Angular의 서비스는 싱글톤으로 알고있는데, 부모 컴포넌트와 하위 컴포넌트가 각각 자신의 Injector로 서비스를 주입받으면, 별개의 서비스 객체를 참조하게 되는 것 같은데, 그러면 완전한 싱글톤이라기보다 injector별로 서비스 객체가 생성된다고 이해해도 괜찮은걸까요?
app.js에서 vue객체를 만들고 그안에 데이터를 정의할 때에는 data : { query: ''} 이런식으로 키-값 형식으로 정의하셨는데, vue compoment에서는 data(){ return{query:''}} 이런식으로 함수 형식으로 정의하셨더라구요. 왜그런지 알 수 있을까요?
안녕하세요, 우선 좋은강의 너무 감사드립니다. 많은 도움이 되고있습니다. 다름이 아니라 DI강의에서 예시로 Car 를 들어주셨는데 1. 기존에 Car 클래스 내부에서 Tire와 Handle객체를 직접 만들어놓았다. Tire와 Handle의 종류가 바뀌면 해당 Class로 가서 다른 타입의 Tire/Handle객체를 만들어야하는 번거로움이 있다. 2. 클래스의 생성자에 필요한 Tire와 Handle을 매개변수로 받도록하고, 팩토리에서 부품들을 모아놓고, 객체를 생성할 때 필요한 부품을 넣어 조립해준다. 1번의 번거로움을 해결하기위해 2번의 방법이 나왔다. 그런데, 2번 또한 생성자에 필요한 Tire와 Handle의 Type을 선언해놓았기 때문에, 결국 Tire와 Handle종류가 바뀌면 1번과 마찬가지로 Car 클래스로 가서 생성자에 선언되어있는 Tire와 Handle에 Type을 바꿔주어야하고, 실제 조립하는 부분도 변경해주어야하는 번거로움이 생기는거 아닌가요?? 1번과 크게 다르지 않다는 생각이 들어서요.. 물론 1번과 다르게 직접 객체는 생성하지 않겠지만요..
posts api로 mainPosts SSR으로 불러 올때, post.User.id, post.User.nickName, mainPosts 데이터도 잘 가지고 오고 있는데요. avatar에 post.User.nickName[0] 한 부분만 자꾸 리렌더링 되는데 따로 설정해야 하는게 있나요?? SSR이 안되는 건가요?
monitor( ) 코드에서 ' close(fd); ' 가 while 문 전에 위치하는데, 이 부분이 잘 해석이 안됩니다. 얼핏 생각해서는 munmap( ) 처럼 모든 일을 마무리하고 함수를 빠져 나가기 직전에 해 주는 것이 '더 적절한' 것이라 생각했는데, 실제 코드는 별 무리없이 작동하기에 더 해석이 안되는 것 같습니다. file mapping 을 통한 shared memory 방식은 실제로는 file I/O 이므로, mmap( ) 이후에 함수 빠져나가기 직전까지 계속해서 스트림이(이 표현이 맞는건지는 잘 모르겠네요..) 살아 있어야 할 것 같은데, 실제로는 그렇게 하지 않아도 코드가 잘 실행되서 잘 이해가 안됩니다.
