시큐리티 + jwt만을 사용한다면 회원가입하고 로그인하면 jwt를 클라이언트에게 보내줘서 다른 요청을 할 때 jwt를 함께 보내고 게시판이 해당 유저인지 판별할 때 예전에는 세션으로 사용했지만 이제는 jwt로 구별한다고 알고있습니다. 그러면 Oauth2 + jwt는 회원가입, 로그인만 소셜로그인 즉, 외부로 빼기만 한거고 소셜 로그인이 성공하면 jwt를 클라이언트에게 주고 그걸로 로그인을 유지한다던지 나머지 역할은 같나요? 소셜 로그인하면 accessToken을 발급해주는데 그거는 단지 서버에서 소셜로그인할 때 연결하기 위한거고 클라이언트에겐 따로 jwt를 만들어서 accessToken, refreshToken을 발급해줘야 하는건가요?

안녕하세요! 강의 진행중 코드에서 오류가 생겨 질문드립니다 ㅠㅠ라벨인코딩 하는도중 cols = train.select_dtypes(include='object').columns cols from sklearn.preprocessing import LabelEncoder for col in cols : le = LabelEncoder() train[col] = le.fit_transform(train[col]) test[col] = le.transform(test[col]) train() 이렇게 작성하였으나TypeError: Encoders require their input to be uniformly strings or numbers. Got ['int', 'str']이런 오류가 나왔습니다 ㅠㅠ 위의 작성된코드를 살펴봐도 어디가 잘못된지모르겠어서, 또 저 에러가 무슨뜻인지 이해가 안가서 질문드립니다 ㅠ 또한, 데이터 전처리 과정 중 다소 불필요한 데이터(?)컬럼(?)을 삭제하지않고 진행할경우 성능이 크게 떨어질까요? ㅠㅠ 괜히 삭제했다가 나중에 뭔가 안맞아서 결과 도출에 오류가 생길까봐 컬럼을 삭제하는게 맘에 걸려서 시험에서는 되도록 그냥 두고싶습니다 ㅠㅠ 괜찮을까요?

안녕하세요 강사님 강의듣던 와중에 질문 있습니다!2회 작업형2에서는 수치형변수 스케일링 과정이 없었고 이번 3회작업형2에서는 수치형변수 스케일링 과정이 있네요. 혹시 이유가 있을까요? 또 3회에서 MinMaxScaler나 StandardScaler를 쓰는것 또한 저의 재량인지 궁금합니다.\ 2회에서는 copy의 과정이 없었는데 3회에서는 copy를 한 이유가 있나요? 시험장에서 어떤방식으로 밀고나가야할지 혼란스러워요ㅠ 괄호안에 ' ' 와 " " 는 동일한가요? 검증데이터 분리시 train_test_split(train.drop('TravelInsurance', axis =1), train['TravelInsurance'] 에서 TravelInsurance를 drop한 이유가 뭔가요? 2회 작업형2에서는 ID를 drop한건 학습할때 필요가 없어서로 알고있는데 해당 문제에서는 Unnamed를 drop해야하는것 아닐까요? 헷갈리네요ㅠㅠ 수치형 변수 스케일링 과정에서cols = ['Age', 'AnnualIncome', 'FamilyMembers', 'ChronicDiseases'] display(n_train.head()) n_train[cols] = scaler.fit_transform(n_train[cols]) n_test[cols] = scaler.transform(n_test[cols]) n_train.head()이 부분에서 2회 작업형 2번처럼 cols안에 여러개가 들어있으므로아래와 같이 반복문을 쓰거나for col in cols: le = LabelEncoder() X_train[col] = le.fit_transform(X_train[col]) X_test[col] = le.transform(X_test[col]) 아래와 같이 일일히 col을 설정해줘야 오류가 안생기지 않나요?# col = 'Warehouse_block' # le = LabelEncoder() # X_train[col] = le.fit_transform(X_train[col]) # X_test[col] = le.transform(X_test[col]) # col = 'Mode_of_Shipment' # le = LabelEncoder() # X_train[col] = le.fit_transform(X_train[col]) # X_test[col] = le.transform(X_test[col]) # col = 'Product_importance' # le = LabelEncoder() # X_train[col] = le.fit_transform(X_train[col]) # X_test[col] = le.transform(X_test[col]) # col = 'Gender' # le = LabelEncoder() # X_train[col] = le.fit_transform(X_train[col]) # X_test[col] = le.transform(X_test[col]) 

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예)[질문 내용]수정, 삭제 벌크 연산의 6:20 부분에서 update쿼리로 인한 영속성컨텍스트 문제를 설명해주셨는데요.전 강의에서 em.flush()실행되는 조건들을 설명해주실 때, 직접 호출 시트랜잭션 커밋 시 JPQL쿼리 실행 시 em.flush()가 실행된다고 설명해주신 것으로 기억하고 있습니다.querydsl도 결국 JPQL기반으로 작동된다고 알고 있는데, querydsl을 통한 select쿼리 실행을 하면 자동으로 em.flush()가 실행되지 않고, 직접 해주어야 하는 메커니즘이 궁금합니다!

const solution = (nums) => { let sumNum = 0 let minNum = Number.MAX_SAFE_INTEGER let oddNums = nums.filter((num) => { return num % 2 !== 0 }) oddNums.forEach((num) => { sumNum += num if (num < minNum) minNum = num }) return [sumNum, minNum] }위와 같이 짜봤는데 비효율적인 코드인가 싶어서 여쭤봅니다! (구지 filter와 forEach를 쓸 필요까지는 없었나 싶어서...) 효율성적인 측면에서 볼 때 어떤지 궁금합니다

마지막 강의를 몇번이나 들었는데 100% 완강 처리가 안되고 계속 98.21%에 머물러있네요

 Question 12주차 이론 블로그 내용에서 내부 노드의 정의가 '루트 노드와 내부 노드 사이에 있는 노드를 뜻합니다.' 로 되어 있는데 여기서 내부노드가 아닌 리프노드가 맞지 않나요? Question 22주차 문제 중 10709 기상 캐스터 문제 코드에서 다음 부분 질문입니다. for(int i = 0; i < n; i++){ for(int j = 0; j < m; j++){ if(a[i][j] == 0){ int cnt = 1; while(a[i][j + 1] == -1){ a[i][j + 1] = cnt++; j++; } } } } 위 코드에서 while 문 내부에서 조건이 계속 만족되면 증가하는데, 인덱스 에러가 발생하지 않는 이유가 궁금합니다. for (int j = 0; j < m; j++) 위 for loop 문의 j < m 까지라는 게 내부 while 문까지 적용되는 건가요?Question3 2주차 문제 4659에서 isVowel을 아래와 같은 방식으로 작성하셨는데요.bool isVowel(int idx){ return (idx == 'a' || idx == 'e' || idx == 'i' || idx == 'o' || idx == 'u'); } ... ... if (isVowel(idx))... 이를 아래와 같이 문자열로 만들어서 이 내부를 탐색하는 건 어떻게 생각하시나요? 저 위에 isVowel도 결국은 각각 일치하는지 탐색하는 거이지 않나요?string f = "aeiou"; int main() { for (char w : word) { if (f.find(w) == string::npos) ... } }

올려주신 수업 자료에서 아래 코드를 하는 이유가 hard fault라고 적어 노셨습니다.아래 코드가 어떤 의미인지 설명 부탁드립니다 SCB->SHCSR = SCB->SHCSR | (7<<16);

마지막 전처리 전후의 표준편차값을 출력할때 제가 혼자 했을때는print(df['distance'].std())print(df_af['distance'].std())로 하였는데 출력결과275.2191532793011267.2360034486679이와 같이 나왔습니다.강의에서 나온바와 같이print(np.std(df['distance']))print(np.std(df_af['distance']))넘파이를 활용하여 계산하였는데 결과는 강의와 동일하게275.0161144074897267.05138442597666 이와 같이 나왔습니다1) 넘파이 라이브러리를 사용한 것과 안한 것의 차이가 나타나는 이유는 무엇인가요?2) 작업유형1 의 경우, 출력결과는 정수형으로 나타내야 하는것으로 알고 있습니다. 두가지 경우, int함수를 사용하면 결과값이 같게 나오는데 이경우에도 풀이는 다르지만 결과 출력값만 동일하면 정답으로 인정되나요?

HTTP 3.0이 기능 개선이 된 것이니 모두 HTTP 3.0을 사용하면 될텐데 왜 HTTP1.1, HTTP2도 같이 사용하는 걸까요? (비슷한 질문이 있긴하던데 삭제됐다네요.)

라이브러리 및 데이터 불러오기 그리고 EDA강의중,17:04->데이터 합치기19:03->데이터 분리하기 부분입니다. N개의 데이터를 합치고 분리할 때2개가 주어진 경우와 3개가 주어진 경우를 안다고 가정하고 ['income']을 기준으로 합치거나 분리하시던데,시험에서는 2개나 3개 중 한가지로만 주어지지 않나요? 그럴 경우 어떤 컬럼을 기준으로 합/분리하는지 어떻게 알 수 있을까요..? 같은 강의의 EDA 전반y_train데이터에 대해서는 결측치나 타입,크기 등을 확인하지 않아도 되는건가요..? 데이터전처리 강의에서 11:00->결측치채우기 -최빈값에서mode() [0] 을 쓰시던데 [0]이 의미하는 바가 무엇인지 알고싶습니다!

안녕하세요.김영한 강사님. Spring boot 프로젝트를 라이브러리(jar)로 만들 때 질문이 있습니다. Spring boot에 있는 내장 tomcat과 관련해서 여쭤보고 싶습니다.(Spring boot 플러그인을 사용하는 경우) Spring boot를 쓰는 프로젝트를 라이브러리로 만들고,다른 Spring boot프로젝트에서 쓰는 경우 내장 tomcat 관련 문제는 없나요?(exclude module: 'spring-boot-starter-tomcat'로 라이브러리가 된 프로젝트에서 tomcat은 제외했습니다) 혹시  만약 문제가 있을 경우에는 보통 어떻게 대처하나요? 추가로 개인 프로젝트에서 비슷한 상황에 대한 질문이 있습니다.spring boot 프로젝트에서 redis를 사용하고 있습니다. redis의 repository를 사용하고 있습니다.(org.springframework.data.repository.CrudRepository) 이걸 다른 spring boot 프로젝트에서 사용할 때,저 repository bean을 생성을 못 하는 것 같은데 라이브러리를 쓰는 프로젝트에서 main에 @ComponentScan으로 라이브러리의 패키지를 주면 그때는 생성합니다. 자동구성 설정에서 scan 범위 관련해서 설정하는 게 있을까요?

안녕하세요.학습자료 요청드립니다.이윤수 / elwmslazz@naver.com으로 보내주시면 감사하겠습니다.

빈 스코프 수강중에 싱글톤 스코프와 프로토타입 스코프를 동시에 사용시 발생하는 문제점으로의존성 주입시 할당된 프로토타입 빈이 계속 유지가 된다는 것이었습니다.이러한 문제점을 해결하기 위해 ApplicationContext를 필드주입을 통해 주입받거나 (가장 간단한 방법), ObjectProvider 또는 자바 표준인 Provider를 사용하는 것입니다. 질문 1.여기서 ObjectProvider<T> objectProvider; 와Provider<T> provider라는 코드에 어떠한 의존성이 주입되는 것인지 궁금합니다.실질적으로 스프링 컨테이너에서 해당하는 빈을 가져오는 부분은 getObject(), get()에서 일어나기 때문에 objectProvider와 provider에는 어떤 의존성이 주입되는지 의문이 들어 질문남깁니다.

강의 대로 Dto 생성자에 @QueryProjection 어노테이션 적용 후 컴파일하여 QMemberDto 클래스 생성 확인이 됐는데 , 테스트 시 위의 그림과 같이 빨간색처리 되며 없다고 뜬다. 무엇이 문제일까요?

안녕하세요.강의를 수강하면서 next 13으로 만들고 있습니다...노드에서 이미지 정적 폴더를 생성하고, 이미지가 서버에 저장되게끔 하는거는 구현했는데,아무리 해도 next에서 서버에 있는 이미지를 불러오지를 못합니다.아래는 제가 시도해본 방법입니다.app.use('/', express.static(__dirname + '/public')); app.use(express.static('public'));express에서 클라이언트 단으로 던져주는 저 app.use 자체가 먹지 않고 있고 아무 에러도 나오지 않아서 너무 답답합니다 ㅠㅠ 어떻게 해야 될까요...?.......
