코딩 질문

작성해주신 코드를 직접 코딩해보며 예제를 익히고 있는데 코드는 똑같이 쓴 것 같은데 영상에서 설명해주신 노란박스가 안떠서 질문을 드립니다. 어떠한 이유에서 저는 노란박스가 화면에 안나오는 걸까요 ? <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> <link rel="stylesheet" href="css/reset.css"> <link rel="stylesheet" href="css/style.css"> </head> <body>  <div class="world"> <div class="stage"> <div class="house"> <section class="wall wall-left"></section> <section class="wall wall-left"></section> <section class="wall wall-front wall-front-a"> <div class="wall-content"> <h2 class="wall-title">1</h2> </div> </section> <section class="wall wall-front wall-front-b"> <div class="wall-content"> <h2 class="wall-title">2</h2> </div> </section> <section class="wall wall-front wall-front-c"> <div class="wall-content"> <h2 class="wall-title">3</h2> </div> </section> <section class="wall wall-front wall-front-d"> <div class="wall-content"> <h2 class="wall-title">4</h2> </div> </section> </div>   </div>  </div>  </body> </html> style.css body { font-family: 'Times New Roman', Times, serif, 나눔고딕; -webkit-overflow-scrolling: touch; color: #555; background: #fff000; } .world { position: fixed; /* 스크롤을 내려도 계속 같은 화면이 보이기 위해서*/ left: 0; top: 0; width: 100vw; height: 100vh; /* 창에 꽉 차도록*/ perspective: 1000px; } .stage { /* 하우스안에 벽이 있고 캐릭터들은 하우스 밖과 월드 사이에 있기 때문에 스테이지 생성 */ position: absolute; left: 0; top: 0; width: 100vw; height: 100vh; transform-style: preserve-3d; /* 월드에서의 3d가 그 밑(자식)의 효과까지 적용되기 위에서 세팅함, ie11에서도 적용안함 webkit적용된 브라우저에서 잘 적용됨 ㅎ*/ } .house { left: 0; top: 0; width: 100vw; height: 100vh; transform-style: preserve-3d; } .wall { position: absolute; left: 0; top: 0; width: 100vw; height: 100vh; background: rgba(255, 255,255, 0.8); }

-webkit-overflow-scrolling: touch;

-webkit-overflow-scrolling: touch; 위의 속성이 크롬에서 확인을해도 invaild property 라고 떠서 찾아보니 https://developer.mozilla.org/ko/docs/Web/CSS/-webkit-overflow-scrolling 이 사이트에서는 더이상 브라우저에서 작동이 안하는 코딩 같아 질문을 드립니다 ! 위의 코딩이 invaild property라고 떠도, 업로드 해주신 코드의 브라우저가 작동하는데 문제가 없었는데, 그렇다면 위의 코드는 어떠한 코딩을 의미하는지가 궁금합니다 !

설계독학맛비's 실전 FPGA를 이용한 HW 가속기 설계 (LED 제어부터 Fully Connected Layer 가속기 설계까지)

코드 리뷰 중 질문

안녕하세요, axi4_lite_v1_0_S00_AXI 코드를 리뷰하는 중 궁금증이 생겨 질문 드립니다. line 237 관련 질문입니다. line 237이 포함된 for loop이 byte_index = 0 부터 3까지 총 4번을 돌게 되면 결국 하는 일은 slv_reg0[31:0] = S_AXI_WDATA[31:0] 인데 (제가 indexed part-selection을 제대로 이해한 것이 맞다면요....) 1) 굳이 for loop을 통해 네번으로 나눠서 할당해주는 이유가 있는지 궁금합니다. 2) for문이 합성이 안된다는 이야기를 들은 적이 있는데, 여기서는 합성이 되나봅니다. 혹시 합성이 되는 for문과 안되는 for문의 차이가 있나요? 감사합니다.

따라하며 배우는 NestJS

@types/uuid를 설치하지 않아도 되나요?

안녕하세요, npm install uuid --save로 uuid를 설치했는데 경고문구가 떠서 npm install @types/uuid --save를 실행해주니 해결되었습니다. 강의에서는 이 부분을 따로 처리해주지는 않던데, @types는 원래 굳이 추가해주지 않아도 되나요?

한번 배워본 대로 문제를 풀어보았습니다.

1. 아 각 숫자가 두개씩 들어있는데 딱 한 숫자만 하나 들어있는 배열에서 하나만 든 숫자를 찾는거구나 2~3. {10, 10, 20, 30, 30, 40, 40, 50, 50, 60, 60} 에선 20이 혼자 {7, 10, 6, 4, 22, 10, 4, 5, 6, 5, 22} 에선 7이 혼자 4. 음 같은 숫자가 두개씩 있는 배열에서 딱 한 숫자만 한개가 들어있으니까 중복을 허용하지 않는 set 자료구조를 사용해보자 5-1. 배열의 각 요소들을 순회하면서 차례대로 set에 넣어보자 5-2. set에 값을 넣을 때 이미 존재하는 값이면 리턴값은 false이다. 5-3. add의 리턴값이 false이면 set에서 해당 요소를 삭제하자 5-4. 모든 요소들에 대한 순회가 끝나면, set에는 딱 1개의 값만 남아있을 것이므로 stream으로 1개의 값을 획득한다. 5-5. 획득한 값을 리턴한다. 6. 즉 제가 제시한 방법의 시간복잡도는 배열의 길이만큼 순회하고, 거기서 다시 논리비교를 매번 하니 O(n²), 공간 복잡도는 O(n)입니다 복잡도가 익숙지 않아서 참 어렵군요 공간복잡도가 헷갈리는데, set에 n개만큼 더했다가 n개만큼 삭제하므로, n²이라고 생각했는데 잘 이해가 안갑니다.공간복잡도는 늘어난 것만 생각하고 줄어드는 것은 고려하지 않나요? 일단 계속 돌려보면서 이해하고 있겠습니당

비전공자를 위한 진짜 입문 올인원 개발 부트캠프

상세페이지 1번에서 데이터를 불러오는데 오류가 발생했습니다.

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요. ㄴ어디서 문제가 발생한지 잘 모르겠네요. postman url 문제인줄 알고 주소 고쳐봤으나 해결되지 않아서 질문드립니다.

[개정판] 딥러닝 컴퓨터 비전 완벽 가이드

공부 방향 설정 문의드립니다

항상 강의 잘 듣고있습니다! 다름이아니라 곤충 개체 인식관련한 오브젝트 디텍션을 수행하고싶은데, 어떤 모델을 사용하는게 좋을지 여쭤보고싶습니다. 곤충이 한마리만 혹은 다수의 개체가 찍힐 수 있게 영상 촬영 장치를 거치해 두고 곤충이 특정 행동을 했을때 알림을 주는 시스템을 만들고 싶은데요, 강의를 들으면서 Efficient Det을 사용하는게 좋을지 다른 모델을 사용해야좋을지 잘 모르겠어서 질문드립니다. 어노테이션부터 일일히 해야하는데 이런경우 어떤 모델을 사용하는게 좋을까요? 찾아보니 이쪽 분야에서는 Yolo를 많이 사용한다고하긴했지만 정확히 모델간의 차이점이 얼마나 크고 작은지 감이 안잡히네요 ㅠㅠ

동영상 끊김현상이 너무 심하네요

버퍼링이 너무 심해서 수강하는데 문제가 있어요 인터넷 환경이 부족한 것도 아니고 다른 스트리밍 사이트 틀어봤지만 아무 문제가 없는데 무슨 일일까요? 다른 날은 전혀 그런 현상이 없었는데 오늘 갑자기 유난히 끊기네요 확인해주세요

자바스크립트 알고리즘 문제풀이 입문(코딩테스트 대비)

안녕하세요!

수업 잘 듣고 있습니다. 풀이 보기 전에 작성한 코드인데 반례가 존재하는지 알 수 있을까요? function solution(arr) { let answer = 0; arr.sort((a, b) => { if (a[0] === b[0]) { return a[1] - b[1]; } else { return a[0] - b[0]; } }); for (let i = 0; i < arr.length - 1; i++) { let people = 1; let s = arr[i][0]; let e = arr[i][1]; for (let j = i + 1; j < arr.length; j++) { let ns = arr[j][0]; if (ns >= s && ns < e) { people += 1; } } answer = Math.max(answer, people); } return answer; }

자바스크립트 중고급: 엔진 핵심

this binding 논리 질문입니다.

강의를 듣다가 제가 제대로 이해한것인지 의심이 들어서 질문드려봅니다! (1) 실행 context는 선언시점에 결정된다고 알고 있는데요. 그럼 this binding도 마찬가지로 선언시점에 결정되고 실행시점에 참조만 교체되는 논리인가요? (2) prototype method 의 경우 어떤식으로 this가 binding되나요? 만약 (1)의 논리가 맞다면 프로토 타입에 메소드가 선언될 때, this binding이 일어나야 할 것 같은데, 실제로 프로토타입을 부르는 객체가 결정되기 전까지는 this 에 대한 정보가 없지 않을까요? 좋은 강의 감사합니다 (_ _)

ssd 학습 결과 궁금증

안녕하세요 선생님, SSD 모델로 학습을 진행하고 있는데 생각보다 오탐지(false positve?)가 너무 많이 잡히고 있습니다. yolo에서는 이렇게 잡히지 않았는데... 이유가 궁금하여 지금 학습하고 있는 config file을 길지만 올렸습니다..(죄송합니다) tensorflow의 ssd를 사용했습니다. mmdetection을 사용하면 결과가 또 다르게 나올까요?? focal loss하고 hard example miner 둘 다 확인해봤습니다. focal loss도 똑같이 오탐지를 하면서 단지 학습의 확신을 주는 느낌으로 밖에 안 느껴졌습니다.!!
