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.

만약 1개의 태그가 4개가아닌 그 이상의 태그가 존재할 경우에는 3/4 이런식으로 명시해주면 정렬이 정상적으로 작동되나요 ? 그 밑으로도 관련 태그들을 정렬하면서 홀수개로 카테고리 갯수가 종료되면 다음 카테고리가 시작되어야하는데 이럴경우 어떻게 대처하는지 궁금합니다.

화면이 에러가 떴는데 도와주세요..

CRUD를 파이썬 shell에서 하는 것보다 장고 어드민 페이지에서 하는 것이 직관적인데요, 실제 장고로 서비스를 운영할 때는 어드민 페이지에서만 CURD를 해도 무방하나요? 아니면 어드민 페이지에서 하지 않고 shell을 활용할 때 이점이 있는지요?

강사님 강의와 다르게 깃헙에 있는 소스들은  let, const로 수정했던 부분들이 var 로 그대로 있는 경우가 있는데 이 부분의 차이로 인한 오류들은 없는건가요?

강의 내용에서 optimizer가 다양한 방식(momentum , AdaGrad 등)을 통해 Local minima 문제를 해결한다는 의미로 이해하였는데, 그림은 Global minima가 아닌 Local minima로 향하기 위해 다양한 방식이 이용된 것처럼 표현되어 질문드립니다. 1.  노란색 선이 의미하는 바가 궁금합니다. 아래 그림의 의미가 노란색 선(타원)이 Local minimum을 의미하고,Local minum을 탈출하여 가운데 global minum에 도달하여 최적화된다는 의미인가요? 2. 각 축의 의미가 궁금합니다. Y축이 error, x축이 진행 순서(t) 일까요? ㄴ
