'spring rest docs1 - 기본설정' 강의를 듣다가 오류가 발생하여 글을 올립니다. gradle 빌드 시 Execution failed for task ':test'. 에러가 발생합니다. 설정에서도 intellij로 설정했는데 왜 그러는지 모르겠습니다 ,그리고 src.docs.asciidoc.index.adoc에서도 오류가 발생합니다

안녕하세요, 강의를 잘보고 잘 이해하고 있다고 생각하고 진행하고 있습니다만, 의문점이 생겼습니다.8비트 정수의 범위를 설명해주실 때부호가 있는(signed) 정수일 경우 범위를 -128 ~ 127로표현해주셨는데요.분명 128의 숫자는 2진수로 표현하였을 때 1000 0000이 맞습니다.이걸 알려주신 '2의 보수' 표현법으로 -128을 나타내면1000 0000 -> 0111 1111 이 되고 +1을 하면1000 0000가 됩니다만 앞선 설명에서는 첫번째 비트공간을음수,양수를 판별하기 위해 사용되는 자리라고 설명해주셔서그렇게 생각하고 있었습니다만 이렇게 될 경우8비트 이니까 128의 2진수인 1000 0000에서 맨앞에 1이 부호를 표현하는 자리이기 때문에 짤리고 000 0000 으로 표현되는 것 이 아닌가요?그렇게 되면 "부호가 있는 정수"의 범위일 경우000 0000 ~ 111 1111(127)이 된다는 건데 뭔가 이상하고그렇다고 1000 0000 을 -0으로 치부해 버리면0을 '2의 보수' 계산법을 통해 계산하였을 경우 똑같이-0 이나 0이나 같은 0000 0000 값이 나와서 이상하고그냥 -128의 경우 +128이나 -128이나 2진수가 같기 때문에 이럴경우는 1000 0000 일때 000 0000 이여도 -128로 정해둔 것 인가요? 아니면 다른 이유가 있을까요?

6분33초에 있는 강력 새로고침은 어떻게 뛰우나요? 우클릭은 안되네요

영한님께서 일대다[1:N]강의에서 1:40 ~ 1:50초 사이에 DB설계관점에서 보면 외래키가 다쪽에외래키가 들어가는것이 좋으며, team쪽에 memberId가 있으면 team을 계속 insert해야하며,team이 중복이 되어 1이 아닌 N이 된다고 하셨는데 이 부분들이 이해하기가 어려웠습니다.외래키가 "다"쪽에 있으면 좋은 이유들과 이 부분들의 이해가 부족할 때 어떤 것들을 공부하면 좋을것 같을지도 알려주시면 감사하겠습니다.영한님의 좋은 강의 덕분에 처음 듣는 내용들인데도, 이해가 잘돼서 너무 좋네요. 좋은 강의 감사합니다

위의 글을 읽어보니 현재 기준 버전의babel-preset-env 에서 async await도 지원을해준다는사실을 알게되었습니다.헌데 강의 시점!!! 영상에서 궁금한것이있습니다선생님께서Promise의 처리를위해useBuiltIns:"usage",corejs:{ version:2} 를 설정해주셨고해당 설명을 통해 require구문 추가가 가능케 하셨고npm install code-js@2 를 통해 설치까지 해주셨습니다 헌데 영상기준으로async await 처리하기위해npm install regenerator-runtime 을 설치해주셨는데왜 regenerator-runtime은corejs에서 처럼 babel.config.js에서 설정을 안해주셔도되는건지 궁금합니다제 생각으론 폴리필의 추가는 babel.config.js에서 하는 것으로 알고있고 그렇다면 npm 설치 뿐만아니라코드상 옵션 설정도 해줘야할것같은데 그런 부분이 없는데도잘 빌드가되어서 이상하다고 생각해서 질문드립니다!!저는 아래 스크린샷처럼 regenerator-runtime을 추가해줘야한다고 생각했습니다

[질문 내용]여기에 질문 내용을 남겨주세요.서버에서도 화면이 안나오고 에러코드를 봐도 잘 모르겠습니다 뭐가 문제 인건가요?

moveInput스크립트에서 점프를 UI버튼으로 통제하려고하는데Awake부문에서 OnClick.AddListener(Jump)를 통해 Jump함수를 불러와 public void Jump(){isJump = true;}을 전달한 후void update(){isJump = false;}업데이트부문에서 UI버튼이 클릭되지 않았을시는 false 계속 반환되게 하려고 만들었습니다. Movement스크립트에서 Jump코드는 그대로 사용을 했을때 Jump함수의 true값이 MoveInput스크립트로 전달이 되지을 않는데 어떠한 문제때문인지를 모르겠습니다.update에서의 false로 하지 않으면 MoveInput 스크립트로 잘 전달은 됩니다. 기존 코드는 Update부분에서jump = Input.GetButtonDown(jumpButtonName);이렇게 받아오는 방식이시던데 저방식도 false로 계속 값을 받아드리다가 버튼 클릭을 통해 한번의 true를 받아오는걸로 아는데 뭐가 다른지 궁금합니다.

java 11 버전은 현재 회원가입이 필요해서 가장 최신버전인 19로 다운받아도 가능할까요...

index.js에서 함수의 이름은 Mainpage인데, app.js에서 불러와서 return할때는 MainPageComponent일까요??이전에 ChildComponent는 함수이름에 Component가 들어가서 이 부분은 그냥 함수명을 그대로 쓰면 되는거구나 했는데.. 함수명에 콤포넌트를 따로 써줘야하는건지 import규칙이 혼선이 옵니다.

안녕하세요유익하고 훌륭한 강의 덕분에 쿼리 이해가 일취월장하고 있습니다. 감사합니다. 강사님께서 거듭 강조하시고 중요하다고 지적하신 "집합의 레벨"이 무슨 의미인지 문의드립니다.group by로 집계하거나 analytic sql로 데이터를 aggregate할 때 "집합의 레벨"이란 표현이 자주 나오는데 어떻게 이해하면 좋을까요? 하나의 행(레코드)가 여러 열(속성)을 가지는 경우에 있어서, 어느 하나의 열을 기준으로 다른 열의 값을 집계할 때, 그 기준이 되는 열을 집계결과의 '집합의 레벨' 이라고 이해하면 될까요? 이전 질문과 같이, 저도 첫 임시테이블(temp_01)에서 group by를 product_id와 category_id 두 열을 기준으로 했습니다. 여기서 첫 임시테이블의 '집합의 레벨'인 product_id이므로 category_id를 또다른 레벨로 두는 것이, 기능상 차이는 없지만 개념상 부적절하다고 생각하면 옳게 이해한 것일까요?  "집합의 레벨"이라는 표현이 모호하게도 들으면 이해되는듯 하면서도 막상 쿼리를 작성할 때 머릿속에 원하는 결과가 흐릿해서 바라는 대로 결과를 얻지 못해 질문드립니다.

int main(){ while (1) { char c; printf("Enter the letter of your choice: \n"); printf("a. avengers\tb. beep\n"); printf("c. count\tq. quit\n"); if ((c = getchar()) == 'a') printf("Avengers assemble!\n"); else if ((c = getchar()) == 'b') printf("\a"); else if ((c = getchar()) == 'c') { int num; printf("Enter an integer : "); scanf("%d", &num); for (int i = 1; i <= num; i++) printf("%d\n", i); } else { printf("\n"); break; } }1. a, b, q 모두 정상적으로 받아들여서, 의도했던 결과를 도출하는데, c만 정상적으로 받아들이지 않습니다. 2. 제가 처음에 char c; 선언 후, c = getchar( );이라고 입력해준 후, 각 조건문에서 getchar( )없이 c == 'b' 이런 식으로 c하고만 비교해주기도 했는데, →a 입력만 받아들이고 끝내버리는 문제가 있었습니다.1과 2 두가지 경우에서 발생한 문제의 원인이 무엇인지 잘 모르겠습니다.

안녕하세요. 제로초님 강의 잘 듣고있습니다.강의를 듣다 getServerSideProps와 swr의 차이점이 궁금해서 질문드립니다.제가 아직 부족해서인지 강의의 내용만을 토대로 생각해보면 getServerSideProps, swr둘다 랜더링전 데이터를 가져와 빠르게 화면을 표시하는 역활같아보이는데코드량이 줄어드는 것 이외에 두 방식의 다른 차이점이 뭔지 알 수 있을까요?
