게임에서 보여지는 3차원 공간은 실제로는 4차원 공간으로 구성되어 있다고 들었습니다!그런데, 제가 이해한 것이 맞는 지 잘 몰라서 질문을 남깁니다!"현실 세계에서 게임 속 3차원 공간의 물체를 바라볼 때, 그 안의 게임(가상 공간)은 4차원으로 구성되어 있다"가 맞을까요?감사합니다.

올려주신 강의 자료에서 6번 코드부터 임포트 했는데 오류가 납니다.

(예)[질문 내용]안녕하세요. 해당 강의와 관련된 내용을 학습하던 중에 prestartAllCoreThreads()외에도 prestartCoreThreads()라는 메서드가 존재하는 것을 확인했습니다.제가 인지한 두 메서드의 차이점은 다음과 같습니다.|메서드 |prestartAllCoreThreads()|prestartCoreThreads()| |---------------|------------------------|---------------------| |생성되는 스레드 수 |전체 코어 스레드 수 |1개씩 | |생성된 스레드의 상태|active 아님 |active |여기서 후자의 경우 1개씩 생성한다는 점은 이해가 가는데, 왜 두 메서드의 경우에서 생성한 스레드의 상태가 active냐/아니냐로 차이가 나는지는 모르겠습니다.챗지피티와 이에 대해서 대화를 좀 나눴는데 그 내용도 이해가 되지 않습니다.다수의 스레드가 동시에 getTask()를 호출하면 모두 블로킹 상태가되어 락을 기다리지 않기 때문에 active 카운트가 증가하지 않는다.. 라고 하는데 이해가 가지 않습니다. 실행 결과// case1. 생성된 스레드가 active 상태가 아님 poolExecutor.prestartAllCoreThreads(); printState(executorService); //15:31:40.628 [ main] [pool=1000, active=0, queuedTasks=0, completedTasks=0 // case2. 생성된 스레드가 active 상태임 poolExecutor.prestartCoreThread(); printState(executorService); //15:17:53.579 [ main] [pool=1, active=1, queuedTasks=0, completedTasks=0 

도서명 입력했는데 원본은 현재 오류상태입니다 라는 팝업이 뜨는데 어떤 게 잘못된 걸까요?

(예/아니오)[질문 내용]제가 강의를 잘못 이해한걸수도 있습니다..   제가 이해하기론 sendError 호출 시 요청 사이클을 내부적으로 한번 더 타는 것이 문제라고 이해했습니다.  필터를 무시하는 방법으론 filterRegistrationBean.setDispatcherTypes(DispatcherType.REQUEST와 같이 필터 설정을 하면 된다고 이해했습니다.  그런데 애초에 디폴트로는 REQUEST 만 설정되는거라면, 필터 사이클을 한번 더 안타는게 맞지 않나요 ?  에러 페이지 요청할 때는 DispatcherType이 ERROR인채로 요청되니까..  그렇다면 강의 초반에 설명해주실때, 클라이언트 요청과 별개로 에러 요청할 때 한번 더 필터 사이클을 탄다고 하신건지 이해가 조금 안됩니다 ㅠㅠ

 이것저것 눌러봐도 안그려지는데 혹시 원인이 뭘까요?

❗질문 작성시 꼭 참고해주세요에러 메세지에서 단서를 찾을 수 있는 경우가 많습니다. 에러 메세지를 읽고 한번 검색해보시는것을 추천드립니다.질문글을 작성하실때는, 현재 문제(또는 에러)와 코드나 github을 첨부해주세요.개발중인 OS, ReactNative, Node 버전 등의 개발환경을 알려주셔야합니다.에러메세지는 일부분이 아닌 전체 상황을 올려주세요. 일부만 보여주시면 답변이 어렵습니다.(일부만 자르거나 일부만 복사하지말아주세요.)  info Opening the app on iOS...info Found Xcode project "MatApp.xcodeproj"info Found booted iPhone 16 Proinfo Launching iPhone 16 Proinfo Building (using "xcodebuild -project MatApp.xcodeproj -configuration Debug -scheme MatApp -destination id=F4F5FF9B-9736-4D9D-BDBD-0877EE044254")info 💡 Tip: Make sure that you have set up your development environment correctly, by running react-native doctor.

(예/아니오) 네[질문 내용]안녕하세요. 영한쌤께서 실무에서는 컨트롤 리소스를 사용하는 경우가 많다고 하셨는데, html form 형태 전송시 post나 get밖에 처리가 안되더라도 이벤트를 prevent한 다음 ajax를 통해서 patch, put, delete하면 되지 않나요? 이벤트 핸들러를 만드는 등의 추가 코드 작업을 해줘야하는 번거로움 때문에 컨트롤 리소스를 사용하는것인지 궁금합니다. 아니면 다른 이유가 있는걸까요?

AtomicIntegerFieldUpdater 기본 구현 페이지의 코드에서마지막 System.out.println() 부분을 보면은 new value라고 하고 instance.getMyFiled()를 하고Updated value에도 instance.getMyFiled()를 합니다그런데 옆에 주석에 new value는 42, updated value는 43으로 나오는데 실제로 실행해보니 저는 둘 다 43으로 나오더라구요 표기 오류가 맞는거겠죠?
