Repository를 fork 해서 실습해보는 중입니다. master에 vue-news가 없어서 다른 branch로 실습을 진행했는데요. Deploy log를 보면 lint를 통과하지 못해서 에러가 발생하는데, 결국 build가 된 것 같습니다. 그런데 강의에서처럼 Preview가 보이지 않아서 확인해보니 아직 Site deploy in progess 상태로 멈춰있었습니다. 원인이 lint를 통과하지 못해서가 맞는지 궁금합니다. 사용한 branch는 3_api, 13_api-advanced 입니다. 로그를 첨부합니다. 4:56:17 PM: 2 errors found. 4:56:17 PM: Module Warning (from ./node_modules/eslint-loader/index.js): 4:56:17 PM: error: Unexpected console statement (no-console) at src/views/UserView.vue:13:25: 4:56:17 PM:   11 |   created() { 4:56:17 PM:   12 |     fetchUser('davideast') 4:56:17 PM: > 13 |       .then(response => console.log(response)) 4:56:17 PM:      |                         ^ 4:56:17 PM:   14 |       .catch(error => console.log(error)); 4:56:17 PM:   15 |   } 4:56:17 PM:   16 | } 4:56:17 PM: error: Unexpected console statement (no-console) at src/views/UserView.vue:14:23: 4:56:17 PM:   12 |     fetchUser('davideast') 4:56:17 PM:   13 |       .then(response => console.log(response)) 4:56:17 PM: > 14 |       .catch(error => console.log(error)); 4:56:17 PM:      |                       ^ 4:56:17 PM:   15 |   } 4:56:17 PM:   16 | } 4:56:17 PM:   17 | </script> 4:56:17 PM: 2 errors found. 4:56:17 PM: You may use special comments to disable some warnings. 4:56:17 PM: Use // eslint-disable-next-line to ignore the next line. 4:56:17 PM: Use /* eslint-disable */ to ignore all warnings in a file. 4:56:17 PM:   File                                 Size               Gzipped 4:56:17 PM:   dist/js/chunk-vendors.04ab93e8.js    126.98 kb          44.01 kb 4:56:17 PM:   dist/js/app.a5b95203.js              5.58 kb            1.97 kb 4:56:17 PM:   dist/css/app.71f56251.css            0.56 kb            0.29 kb 4:56:17 PM:   Images and other types of assets omitted. 4:56:17 PM:  DONE  Build complete.

고박사님의 강좌를 보면서 직접 코딩도 하고, 강의대로 정상 작동하는지 테스트 하면서 하느라 시간이 많이 걸리지만 하나씩 배우면서 잘 작동하는것을 보니 뿌듯합니다. ^^;   그런데 강의대로 모든 Scenes 및 코드들을 작성 및 실행하고 난후 강의가 끝난후 다시 확인하던 중에 강의중 화면에는 #05MoveByTransform 씬이 있는데 이 씬에 대한 설명이 없던데 무엇을 하는 씬인지요?

- 학습 관련 질문을 남겨주세 모델링 보면서 공부하고 복습하면서 다른거는 왠만큼 사각형을 유지하면서 모델링은 하겠는데 이러한 부분은 어떻게 사각형으로 폴리를 구성하는지 알고싶어요!     . 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.

#include <stdio.h> #include <stdlib.h> int main(int argc, char* argv[]) { int ch; FILE* fr; unsigned long count = 0; if (argc != 2) { printf("Usage : %s filename\n", argv[0]); exit(EXIT_FAILURE); } if ((fr = fopen(argv[1], "r")) == NULL); { printf("Can't open %s\n", argv[1]); exit(EXIT_FAILURE); } while ((ch = fgetc(fr)) != EOF) { fputc(ch, stdout); count++; } fclose(fr); printf("FILE %s has %lu characters\n", argv[1], count); return 0; } 보시는 바와 같이 코드를 강의코드와 똑같이 작성하고 소스코드와 같은 위치에 txt파일을 만들고(내용도 강의와 똑같습니다) 명령줄 인수도 올바르게 넣었는데 작동이 안됩니다. 실행시 Can't open my_input.txt 라 출력되는것을 보면 인수는 잘 들어갔는데 텍스트파일을 찾지 못하고 있습니다. 도대체 어떤 이유에서인지 알고 싶습니다. 부탁드립니다.

현재 /members/new 로 이동하는 부분에서 막혔습니다. /members/new 로 이동하면 아래와 같은 화면이 나옵니다. home.html, MemberController, createMemberForm은 아래와 같습니다. members 파일을 templates에 넣은 것도 확인했는데 어느 부분에서 잘못된 것인지 모르겠습니다.. createMemberForm.html 대신 이전에 잘 작동했던 hello.html을 넣어봐도 같은 에러가 뜹니다..    

실습 중에 실수로  a dict에는 'bitrh' : 901113 으로 저장되어 있었는데 a.update(birth = 900112) 로 출력했더니 기존 bitrh 과 birth 키 모두 존재했습니다. update 메소드로는 추가가 되는 것 같은데 수정에만 사용하는 건가요??

맥북 사용자입니다. 코드를 똑같이 적었는데 실행이 되지 않아요...  from selenium import webdriver browser = webdriver.Chrome() brower.get("http://naver.com") 하고 run했지만 에러가 뜨네요...  터미널에서도 해보았지만 browser = webdriver.Chrome()에서 에러가 나요.. 에러를 어떻게 없앨수 있을까요?

개발 공부 팁 같은 것 있나요?

호, 혹시 향후 어떤 주제의 대한 강의가 나오는지 미리 알 수 있을까요?

#include<iostream> #include<string>   int main() {   using namespace std; int a; cin >> a; string name; getline(cin, name); }   실행시키면 변수 a 만 입력을 받고 변수 name은 입력을 받지않고 끝나버리는데 왜그런가요? 이유를 알려주세요. 개행이 버퍼에 남아있다는게 무슨소린지 잘 모르겠네요. 처음부터 알려주시면 감사하겠습니다.

=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 아니오3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용] 안녕하세요. item.html 타임리프를 적용한 후 상품명을 눌러 실행해보니 아래와 같은 오류가 뜹니다.   Resolved [org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'long'; nested exception is java.lang.NumberFormatException: For input string: "null"]   상품명을 눌러서 에러가 났고, NumberFormatExcption이 나와서 BasicItemController에서 {itemId}로 매핑하는 코드를 확인했습니다. 파라미터로 의 값을 'long'으로 받고 있었습니다. 그런데 브라우저 주소를 치니 http://localhost:8080/basic/items/null 'null'이 나왔습니다. 반환타입과 'null'은 서로 맞지 않으니 오류가 난다고 파악했습니다. 그렇다면 반 null값이 안나오게 바꿔줘야하는데 어떻게 해결 해야하는 지 잘 모르겠네요. 도움 요청합니다!       BasicItemController의 코드는 다음과 같습니다. ------------------------ @Controller@RequestMapping("/basic/items")@RequiredArgsConstructorpublic class BasicItemController { private final ItemRepository itemRepository; @GetMapping public String items(Model model) { List<Item> items = itemRepository.findAll(); model.addAttribute("items", items); return "basic/items"; } @GetMapping("/{itemId}") public String item(@PathVariable long itemId, Model model) { Item item = itemRepository.findById(itemId); model.addAttribute("item", item); return "basic/item"; } @PostConstruct public void init() { itemRepository.save(new Item("itemA", 10000, 10)); itemRepository.save(new Item("itemB", 20000, 20)); }]   --------------------- 상품명에 관한 코드는 다음과 같습니다. <div> <label for="itemName">상품명</label> <input type="text" id="itemName" name="itemName" class="form-control" value="상품A" th:value="${item.itemName}" readonly></div>  

안녕하세요,  myip_v1_0_s00_AXI.v  line 299부터의 질문 입니다. 제가 이해한 바로는, mem0_addr_write_hit가 발생했을 때, 우리는 mem0_addr를 0 으로 초기화하기로 했기 때문에 line304가 "mem0_addr_cnt <= 0;"으로 변경되어야하는 것이 아닌가요?   그래서 mem0_addr_reg을 따라가보니 이전 line291에서 이렇게 선언되어 있고 외부 모듈 (myip_v1_0.v)에서는  또 외부에서 input으로 들어오고 있던데 제가 놓치고 있는 부분이 있는것일까요?   제 짧은 생각으로는 그냥 0을 할당해줘야 한다고 생각했었습니다.   감사합니다.  

강의 내용과 같이 hello-spring 있는 파일까지 가서 gradlew을 했는데 다음과 같은 오류가 발생했습니다. window 사용하고 있고, 잘못했거나 다른 방식을 제안해주시면 감사하겠습니다!  

# 팩킹 & 언팩킹 , 괄호는 튜플에서 생략 가능 t2 = 1,2,3  #팩킹 t3 = 4,   x1,x2,x3 = t2 # 언팩킹 --> 팩킹된 튜플의 값을 x1, x2, x3에 할당 x4,x5,x6 = t3 # 언팩킹  print() print(t2) print(t3) print(x1, x2, x3)   출력하면 ValueError: not enough values to unpack (expected 3, got 1) 이렇게 출력이 되는데 t3 = 4,가 문제되는건가여?

안녕하세요? 선생님   CVAT로 객체검출 레이블링을 하려고 CVAT를 사용하고 있습니다.   설치방법이 까다로워 느리지만 웹기반으로 사용중입니다. 이미지를 조금씩 업로드해서 작업하려고 하는데, 기존의 이미지의 레이블링 작업이 끝나서 다음 작업으로 넘어가려고 하는데, (Task에 Job을 추가하면 될 것 같은데?)   메뉴도 버턴도 찾을 수가 없습니다. 최약의 경우 다시 Task를 정의하면 되겠지만, 그러면 많이 불편할 것 같습니다. 좋은 방법이 있을까요?   그럼 오늘도 좋은 하루 되십시오 감사합니다.

- 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.   기본적은 함수 구현은 선생님이랑 똑같이 했는데 왜 qna answer을 실행하면 안되는지 모르겠습니다.   페이지 검사를 해보면 Cannot read properties of null으로 나옵니다. 첨부사진 드리겠습니다.              

안녕하세요 선생님. 만약 두 자리수 이상의 숫자도 후위식 연산이 가능하게 하려면 어떤 식으로 코드를 짜면될까요?

안녕하세요 강사님. 좋은 강의 잘 듣고 있습니다! 몇가지 궁금증이 생겨 질문드립니다.   static int Factorial(int a)         {             if (a == 0)             {                 return 1;             }             return (a * Factorial(--a));         } 제가 작성한 코드입니다. 정상적으로 실행은 됩니다만, 몇가지 사소한 궁금증이 있어서 올려봅니다. 1.  a==0이 참일때 return 값을 1으로 주는 것보다 n==1이 참일때 return 값을 1로 주는게 더 효율적일까요?(루프를 한번 덜 돌까요?) 2. 강사님께서 if문의 조건식을 n<=1로 작성하셨던데 n==1이 아니고 n<=1로 설정하신 이유가 따로 있을까요? 3. factorial(n-1)부분을 전위 연산자(--a)로 먼저 처리하게 하였는데, 후위연산자를 사용하여 return (a*Factorial(a--))로 하면 return (a*Factorial(a))가 먼저 실행되고  a--가 실행되기 때문에 무한루프를 돈다고 이해했는데 맞을까요? 아니라면 혹시 다른 이유가 있을까요?
