강의 잘듣고있습니다~!!deking1772@gmail.com 입니다.

local에서는 userInfo 가 제대로 넘어오는데vercel 배포후에는 userInfo가 html태그로 넘어오는건 뭐 때문일까요..?

선생님 안녕하세요좋은 강의 감사합니다.일급함수 - 클로저 심화(3-2), 강의 파일 5-3 에서 질문이 있습니다.비슷한 아래 질문들을 모두 읽어봤는데도, 확실하게 궁금증이 해소가 되지 않아 질문드립니다. 선생님께서 비슷한 질문들에 달아주신 링크에 있는 글 들은 모두 읽어보았습니다.기본적으로 nonlocal 변수들을 참조해서 수정할때는, nonlocal 을 달아주는 것이 원칙이고,다만, list, dict의 경우 "예외적으로 수정이 가능하므로 nonlocal을 달아줄 필요가 없다" 라고 이해해도 되나요?그리고 선생님의 답변 중에, 스코프 별 변수의 생성주기에 대한 강의를 참고하라고 답변 달아주신 부분이 있는데 이 부분을 잘 못찾겠습니다. 강의 지점 알려주시면 감사하겠습니다.감사합니다!

선생님 강의를 듣고 간단하게 코드를 짜봤습니다.@GetMapping("") public String community(Model model){ List<BoardDto> boardDtoList=userService.getBoardList(); model.addAttribute("BoardDto", boardDtoList); System.out.println("model:" +model); return "community"; }위 코드는 getMapping 하여 community를 불러오는 함수 입니다.@GetMapping(value = "/delete/{id}") public void boardDelete(@PathVariable("id")Long id, Model model) { try { userService.deletePost(id); } catch (Exception e) { model.addAttribute("errorMessage", e.getMessage()); } community(model); }위 코드에서 처음 만들었던 community 함수를 사용하여 return "community"를 생략하는 방식으로 코드를 구현하면 org.thymeleaf.exceptions.TemplateInputException: Error resolving template [community/delete/1], template might not exist or might not be accessible by any of the configured Template

test 코드를 작성해보면 정상적으로 model 값이 넘어가는 것을 확인해봤는데 왜 웹 상에서 return "community"를 못하는 걸까요??궁금해서 잠이 안와 질문드립니다...ㅜ요약하자면 @Controller 가 붙은 클래스 내의 함수를 다른 함수를 구현하는데 이용하면 문제가 되는건가요???

여기서 강사님께서 말씀하신대로 파일 클릭해서 들어간다음 새로고침 해서 확인해보면 304, last-modified, if-modified-since등이 잘 나왔음을 확인 할 수 있었습니다. 하지만 저 사진과 같은 상태(구글에 hello 검색하고 새로고침 할때)에서는 200만 나오고 cache-control:max-age가 0이 나오는데 이유를 알 수 있을까요??

stateNotifier에서 사용하면 해당 페이지 나갔을 때 다시 초기값으로 돌려주는 건가요?

호돌맨님 안녕하세요강의 진행중 사용하는 My Json Editor Tool 은 혹시 어디서 다운로드 받을수 있을까요? 안내해주시면 감사하겠습니다 ㅎㅎ

SELECT DISTINCT lags.num1 AS ConsecutiveNumsFROM (SELECT id, num AS num1, lag(num) OVER(ORDER BY id) AS num2, lag(num,2) OVER(ORDER BY id) AS num3 FROM logs ) AS lagsWHERE lags.num1 = lags.num2 = lags.num3 으로 하면 1과 2가 나오네요 ㅎㅎ ㅠ FROM 절 서브쿼리만 따로 돌려봤을 때에도 num1~3이 모두 같은건 1밖에 없고 테이블을 심플하게 엑셀로 생각해봐도 lead나 lag나 다를게 없어보이는데 최종적으로 돌려볼때는 자꾸 1,2가 모두 나와서요

nodeport 테스트중 궁굼한 사항이 있어 문의드립니다.k apply -f Lecturek8s_learning.kit/ch4/4.3/nodeport.yaml우선 위 파일을 실행 시켰습니다.실행은 정상적으로 되었는데요.아래와 같이 첫번째 pod에 접속해서 index.html을 수정하고자 하면 내용이 아무것도 없는것으로 나옵니다. (2,3번째 pod는 정상적으로 노출됩니다.) 혹시 발생하는 원인을 알 수있을까요? (제거 후 새로 생성해도 동일하네요.)예제 파일에서 nodePort를 30000으로 강제하고 있는데요.(nodePort: 30000)실제 w1-k8s, w2-k8s, w3-k8s 노드로 접근 후 'netstat -napt | grep 30000' 명령어를 실행해 보면 30000 포트가 없습니다. (동작은 정상적으로 되는것 같습니다만..) 노드마다 30000가 열려있어야 하는게 아닌가요? (k get svc시 노드별 30000포트가 열려있는게 맞죠?)브라우져(브라우져 캐시도 껐어요)에서 nodeIP:3000으로 접속시 2번 pod로만 접속이 됩니다. (exec로 내부 index.html을 변경해서 테스트했습니다.) clusterIP로 curl 로 테스트 할때는 로드밸런싱이 되는데요. 노드:30000으로 접근시에는 2번으로만 접속이 되는데요. 이 부분도 이유를 알 수 있을까요? (참고로, 노드포트로 접속시에도 로드밸런싱되는 것으로 알고있습니다.(curl로 노드에서 직접 테스트해보면 또 로드밸런싱이 되네요--;)노드ip:30000 로 접속시 clusterIP -> pod 로 접근되는건 맞나요?질문이 많네요. ㅎ확인 부탁드리겠습니다.^^

맥 가상환경 진입 명령어는 조금 다르더라구요.맥 쓰시는 분들 참고하세요~source venv/bin/activate +) 가상환경 나올 때는deactivate쓰시면 됩니다.제가 참고한 글은https://velog.io/@ssssujini99/Django-%EA%B0%80%EC%83%81%ED%99%98%EA%B2%BDVirtual-Environments%EC%9D%B4%EB%9E%80-Pycharm%EC%97%90%EC%84%9C-%EA%B0%80%EC%83%81%ED%99%98%EA%B2%BD-%EC%84%B8%ED%8C%85%ED%95%98%EA%B8%B0입니다.

원하는 결과값은 잘 나오는데, 재부팅해도 계속 멈추지않고 동작합니다.

단어 추측이 성공하는 경우의 if문의 실행 조건이 failed 가 0일 때 인데 만약 처음 키 입력에서 실패하고 여러번의 시도 끝에 성공 할 경우 failed의 수가 0이 아닐텐데 어떻게 단어 추측 성공부분이 실행 될 수 있는 건가요?

이러한 API_URL은 어떻게 알 수 있을까요 ? https://www.themoviedb.org 사이트에 정보가 나와있는 걸까요 ?

뭐가 문제일까요?

use after free, 댕글링 문제 스마트 포인터를 통해 메모리 오염 막을 수 있는거 알겠습니다.그런데 지금 k2가 {} 지나면 유효하지 않은데k2의 데이터자체는 사용할 수 없을 텐데...굳이 또 k1->Attack()을 호출할 필요가 있는것인가요..??

강의에 나온 b데이터 (section .data 에 b times 5 dw 1) 를 모두 출력해보는 연습문제에서 PRINT_HEX 2, [b+ecx]는각각 1 / 100 / 1 / 100 / 1 으로 출력되어서 100이 나오는 이유까지는 이해가 됐는데 PRINT_DEC 2, [b+ecx] 라고 하면각각 1 / 256 / 1 / 256 / 1 이 출력되는데 256이 나오는 이유를 잘 모르겠어서 질문드립니다.

class RefCountBlock{public :int _refCount = 1;};template <typename T>class SharedPtr{public :SharedPtr() { } // 이대로 놔두면 nullptr로 아무것도 안하는 존재가 된다.SharedPtr(T* ptr):_ptr(ptr){if (_ptr != nullptr){_block = new RefCountBlock();cout << "RefCount : " << block->refCount << endl;}}SharedPtr(const SharedPtr& sptr):ptr(sptr.ptr),block(sptr.block){if (_ptr != nullptr){block->++refCount;cout << "RecCout : " << block->refCount << endl;}}void operator = (const SharedPtr& sptr){ptr = sptr.ptr;block = sptr.block;if (_ptr != nullptr){block->++refCount;cout << "RecCout : " << block->refCount << endl;}}~SharedPtr(){if (_ptr != nullptr){block->--refCount;cout << "RefCount : " << block->refCount << endl;if (_block->_refCount == 0){delete _ptr;delete _block;cout << "Delete Data" << endl;}}}public :T* _ptr;RefCountBlock* _block;};지금 이런 상태에서 제가 미미하지만 조금의 성능향상을 위해서(후위연산자 버젼은 어차피 임시객체를 만들어서 반환하고 삭제되기 때문에)block->++refCount값을 이렇게 '전위 연산자'로 증가시켜주었는데, 이게 지금 id_expression이라는 에러가 나더라구요...후위연산자로 해줄 경우에는 에러가없고...그래서 제가 "아 SharedPtr이라는 클래스를 만들고 거기에 해당하는 연산자 오버라이딩을 안해주어서 그랬구나! "라고 생각했다가.. 연산자 오버라이딩 문제는 아닌거같다라고 판단이 들었습니다.전위연산자(++)를 오버라이딩 안해주었다면 후위연산자도 오버라이딩이 안되어 block->refCount++; 도 동작하지 않을 것인데... 라고 생각했습니다.그래서 분명 _refCount는 기본자료형인 int자료형이라 전위, 후위 다 지원을 분명히 하는데 왜_block이라는 포인터를 통해서 접근해서 바로 전위 연산자를 사용할 수 없는 것인가요??_block->(++_refCount) 의 경우에도 같은 에라가 납니다

public static void main(String[] args) throws IOException { BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out)); }여기서 throws IOException (예외처리)를 반드시 붙여 주어야 한다는 거는 그냥 의식적으로 알기만 하고 있는데 왜 해야 하는 지 이유를 알려면 어떤 것을 참고하면 좋은가여?
