안녕하세요. 배포 직전  docker에서 여러가지 연동중에 사이트를 띄우면 static파일이 계속해서 적용되지 않습니다. ㅠㅠㅠㅠ gunicorn 설명 시작 전에도 강사님이 Dockerfile, CMD에서 runserver 명령으로 사이트 실행하실때도 무사히 static이 적용되는 것을 보았습니다. 하지만 저는 그 때부터도 스타일 적용에 실패했는데요.  named_volume파트 이후에도 static에서 css, js를 계속해서 불러오지 못하네요... 이미지는 여차저차 되는거 같은데...ㅠㅠㅠ <오류코드> <Dockerfile> <git 주소> https://github.com/soyolim-txter/BAS.git

이런식으로 강의하실때 10가지가 뜬다고 하는데 전 한가지만 뜨고 있고 맨마지막에 +9 오버로드 라고 나와 있는데 이거 다른걸 보려면 어떻게 해야 하는지 알려주시면 안될까요?

선생님, 저는 이렇게 풀어봤는데 이것도 정답일까요..? function solution(m, arr) { let cnt = 0; let sum = 0; let leftIndex = 0; for (let rightIndex = 0; rightIndex < arr.length; rightIndex++) { while (sum <= m) { cnt++; sum += arr[rightIndex]; } if (sum > m) { sum -= arr[leftIndex]; if (sum <= m) { cnt++; } } } return cnt; } let a = [1, 3, 1, 2, 3]; console.log(solution(5, a)); // 10

회원가입을 커스텀훅으로 만드신 강의 부분에서 질문입니다. 어떤 분이 useCallback을 props로 자식 컴포넌트에게 넘겨줄 때만 사용해라 라는 말을 들은 적이 있어서 언제 useCallback을 써야할 지에 대해 감이 안옵니다ㅠㅠ const handler = useCallback(({ target }) => { setValue(target.value); }, []); 제가 생각하기에 여기서 useCallback을 사용하신 이유는 useInput()을 호출할 때마다 함수가 생성될테니까 useCallback을 사용했다고 생각했습니다. 이게 맞을까요? 그리고 현업에서는 보통 useCallback을 언제 사용하는지 궁금합니다.

자꾸 npm run start 할 때  MongooseError: The `uri` parameter to `openUri()` must be a string, got "undefined". Make sure the first parameter to `mongoose.connect()` or `mongoose.createConnection()` is a string. 오류가 발생합니다. https://github.com/Lee-Sw/boiler-plate 오타때문인가 자꾸 보는데 확신이 없네요. 확인 가능하시다면 부탁드립니다.

말씀하신대로 쿼리는 짰는데 답을 보니까... 왜 A로 시작하는 것들이 포함되어 있는거죠?? 제가 OR을 잘 이해를 못하고 있는 건가요?

jupyter나 colab을 이용해도 될까요?!

build.gradle에 JWT 관련 라이브러리들을 추가한 후 적용하게 되면 다음과 같은 오류가 발생합니다 ㅠㅠㅠ 어떻게 해결할 수 있을까요?? 여기서 진행을 못하고 있습니다 ㅠㅠㅠㅠ build.gradle은 혹시 몰라 github에 올리신 소스코드에서 복사까지 해보았지만 똑같은 문제가 계속 발생하네요 ㅠㅠ error message :  A problem occurred evaluating root project 'jwt-tutorial'. > Could not find method compile() for arguments [io.jsonwebtoken:jjwt-api:0.11.2] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler. * Try: Run with --info or --debug option to get more log output.

안녕하세요 그랩님 soldout이 1일때 blur 처리가 안돼서 질문 남깁니다 그냥 <div className="product-blur" />로 들어가면 블러 처리가 되는데 {product.soldout === 1 &&  <div className="product-blur" />} 로 작성하고 나면 soldout이 1인 상품에 블러처리가 되지 않습니다. DB.Browser에서 확인해봐도 soldout부분은 1로 되어있는데 왜 그런걸까요? web, server 코드 다 올려봅니다 다른 부분 확인해보셔야할데가 있다면 알려주시면 바로 올리겠습니다 항상 감사합니다 <div id="product-list"> {products.map(function (product, index) { return ( <div className="product-card"> {product.soldout === 1 && <div className="product-blur" />} <Link style={{ color: "inherit" }} className="product-link" to={`/products/${product.id}`} > app.post("/purchase/:id", (req, res) => { const { id } = req.params; models.Product.update( { soldout: 1, }, { where: { id, }, } ) .then((result) => { res.send({ result: true, }); }) .catch((error) => { console.error(error); res.status(500).send("에러가 발생했습니다"); }); });

body { display: flex; align-items: center; justify-content: center; transform: perspective(1000px); /* perspective: 1000px; */ color: black; background: #fff000; } 위와 같이 transform 속성에 perspective를 주어도 똑같은건가요 ? 두개 같은 문법이라면 보통 어느 표현을 더 자주 사용할까요 ?? 애니메이션 효과가 조금 부족한테 유튜브 영상으로만 들어도 충분할까요 아니면 다른 강의도 결제해서 듣는게 나을까요?

노트 패드 ++ 설치 후 exec를 설치하려는데 plugin package가 존재하지 않는다는 오류가 뜹니다  어떻게 해결해야할까요? 

 float를 썼는데도 clear를 안 써도 되는 경우라면 width와 height를 따로 지정해 줘서 float가 안 먹는 걸까요?? 아님 다른 이유가 있는 걸까요?

1. EntityTransaction.commit 하면 flush() 가 먼저 일어난다. 2. 영속성 컨텍스트에 있는 변경 내용을 DB에 동기화한다. (쓰기지연SQL에 있는 SQL을 전송한다. , 저장은 안됌!) 3. 마지막으로 데이터베이스의 Commit을 하여 저장이된다. 이렇게 이해했는데 맞을까요 ?

IE11 지원은 되는데 핫리로드가 안되는것같네요 혹시 확인가능하신가요

다른건 다 이해를했는데  class MyList<T> where T : new()  에서 이해가안갑니다. 반드시 어떠한 인자를 받지않는 기본생성자가 있어야된다는 조건을 넣을수있다는게 이해가안갑니다..  제가지금 테스트할떄는 생성자가없어도 잘되는데 .. 뭐가문제인지 잘이해가안갑니다.

JPA가 쓰기지연으로 인해 한 트랜잭션 안에서 엔티티를 몇개를 persist 하던간에 commit을 만나기 전까지는 1차캐시 저장소와 쓰기지연 sql 저장소에 각각 보관해두다가 commit을 만나면 DB에 insert 쿼리를 날리는거 맞나요 ?? 그렇다면 batch_size  옵션이 전 무의미하다고 느껴져서요 !! 어차피 이 옵션이 있던지 없던지 한번에 쿼리는 날리는데 어떤의미가 있는지 잘 와닿지가 않습니다.

강사님 쿠버네티스 아키텍처를 너무 잘 설명해주신 덕분에 이해도가 많이 올라갔습니다 감사합니다!  노드의 kubelet 역할에 대해 문의 드립니다! 파드 추가를 api에 호출하면  controller 와 스케줄러를 거쳐 파드가 노드에 배치되고 노드에 kubelet pod 상태 업데이트를 한다고 했는데  이미 노드에 배치 된 파드를 큐블릿이 관리 목적으로 상태를 체크해 주는건가요? 아니면 큐블릿이 상태 업데이트를 끝내야 파드가 빈 노드에 정착?을 하는건가요?  kubelet은 단순 마스터서버에 의해 만들어진 파드가 잘 살아있나 헬스 체크만 하고 다른것은 아무 관여를 하지 않나여?

수강을 하는데 영어로 된 용어의 발음이 너무 이상해요... Tile을 틸레로... Alignment를 얼라이지엔먼트... 듣기가 민망하네요.
