if ((14 > 13 || 2 > 1) && (9 > 1 ))에 대해 출력을 해봤습니다.저는 14>13은 false이고 2>1은 false이기 때문에 (14 > 13 || 2 > 1) 부분이 false가 돼서 정답은 false가 출력 될 것이라고 생각했습니다.그런데 정답은 true로 출력이 됩니다. 왜 이런지 알고 싶습니다!

수고하십니다.우선 한국어로 이렇게 심도깊은 토큰강의를 만들어주셔서 많은 공부가 되었습니다. 실제 실무에 적용할때 질문이 있습니다.지금의 토큰 플러그인으로 color부터 sizing, spacing등 많은 카테고리 토큰이 작성 가능한데요.피그마로 한 App의 일부페이지를 디자인했을때 개발자에게 공유하면, HandOff기능으로 별도툴인 제플린도 그렇고, 피그마에서 직접 개발자가보기에 토큰명이 나오지않는데요. 그래서 토큰이 사용된것을 알 수 가없습니다.이런경우에는 개발자도 피그마에서 토큰스튜디오 플러그인을 통해 공유받은 디자인페이지에 사용된 토큰값들을 확인하며 작업해야할까요?

첫번째 질문은 i2c 컨트롤러 설계를 위해 reg8*8 모듈이 필요한 이유가 슬레이브 모듈이 예를들어 온습도센서라 가정하였을때 온도,습도값들을 저장하기 위해서 필요한것인가요? 즉 슬레이브에서 마스터로 보내주는 데이터를 저장하기 위함인가요? 잘모르겠어서 질문드립니다. 항상 수준낮은 질문드려서 죄송합니다.

chatGPT API를 테스트하고 있는데요chatGPT 사이트와 달리 문장을 모두 완성한 뒤에야결과를 보내주더라구요.그래서 결과가 나올 때까지 10초 이상 걸리기도 합니다.중간에 글자가 나오면 아무래도 덜 지루하게 기다릴 수 있어서글자가 중간에 나오게 하는 방법이 궁금합니다.

슬라이드 가로-> 세로를 잘 연습해서위 -> 아래로 제작 했는데 이거는 이상하게 나오는데 뭐가 잘못된건지 모르겠습니다 ㅠㅠ

부분이 이렇게 선언이 되어 있었는데@ManyToOne(fetch = LAZY) @JoinColumn(name = "member_id") private Member member; 오류를 보고 나서 cascade = CascadeType.ALL 옵션을 추가해주니까 오류 없이 동작을 하긴 하는데 이게 맞나 싶어서 문의드립니다..@ManyToOne(fetch = LAZY, cascade = CascadeType.ALL) @JoinColumn(name = "member_id") private Member member; 발생 오류입니다.인텔리제이 콘솔에 찍힌 로그이고요..org.hibernate.TransientPropertyValueException: object references an unsaved

long horn 을 설치 하고 볼륨을 생성 하면/var/lib/longhorn 으로 path 가 만들어 지는데path 를 원하는 곳으로 옮길수 있을까요?Setting 부분을 바꿔도 안되고long-horn.yml 파일의 mount path , volume 부분을 변경해도 안됩니다.방법이 있을까요?       

선생님 안녕하세요 저는 현재 cityscape dataset을 바탕으로 kaggle mask_rcnn_nucleus 코드를 활용하여 segmentation을 해보려고 하고 있습니다.그에 따라 cityscape 데이터를 nulceus 데이터와 동일한 구조의 디렉토리로 정리하였는데요,이를 coco 포맷으로 변환하려고 하니, 아래 오류가 떠서 문의드립니다.파일 경로는 모두 맞게 입력한 것 같은데, 이미지를 못 읽고 있는 것 같습니다..

Todo List 05 - UI 작성 24:04 초 에서 @Composable TodoItem 파라미터 중 onClick 이 사용되지 않고 넘어가고 있습니다.영상이 누락된 것 같아보여서요.[누락화면][해결화면]Github 소스코드는 onClick 내용을 반영하고 있는걸 확인했습니다.

저도 윈도우의 안드로이드 스튜디오로 선생님의 파일을 다운받아 실행했는데요, 터미널이 동일하게 열리지 않습니다. 그래서 node.js commend를 실행해서 npm i 등을 실행하면 아래와 같은 오류가 발생합니다. 해결책을 모르겠습니다ㅜ

 type IsNever<T> = T extends never ? true : false일때 웹스톰에서는 이니셜 타입을 true로 추론하고vscode에서는 never로 정상 추론하는데웹스톰에서는 이게 정상인건가요??

원영님 강의를 보고 현재 스프링 프레임워크 기반의 회사 솔루션에 카프카 도입을 구현하고 있습니다. 터미널 상에서 컨슈머와 프로듀서는 잘 주고 받는데 IDE로 넘어와 적용하면 에러가 발생합니다브로커의 로그를 확인해보니 Processing automatic preferred replica leader election (kafka.controller.KafkaController)Checking need to trigger auto leader balancing (kafka.controller.KafkaController)Topics not in preferred replica for broker 0 Map() (kafka.controller.KafkaController)이런 로그들이 찍히는데 구글링해도 이렇다 할 해결방법을 못찾고 있습니다 컨슈머 프로퍼티에 부트스트랩 서버도 localhost:9092 프로듀서 프로퍼티의 부트스트랩 서버도 동일하며 서버 프로퍼티의 애드버타이즈드 리스너도 localhost:9092로 설정해뒀습니다혹시 제가 빠뜨린 부분이 있을까요? 도움 주시면 감사하겠습니다..

이전 강의 중 Stream에 대해 설명해주셨을때 크기가 큰 Stream을 TCP에 넘겨줄때 MSS에 따라 segmentation이 된다라고 이해했습니다.그런데 "TCP 연결 과정"에서도 Client와 Server의 MSS가 다를 때에도 낮은 MSS에 맞춘다고 이해했습니다. 강의 예시처럼 Client의 MSS가 1460, Server의 MSS가 1400일때 Server의 MSS에 맞춰버린다고 하면 이때 어느 부분에서 일어나는 건가요?SYN+ACK를 통해 server의 MSS를 받고 L2->L3->L4(TCP)로 가서 한번 더 segmentation이 일어나는 건가요?3-way handshaking을 할때에도 en/decapsulation이 일어나는게 맞는가요?

안녕하세요,저는 'category'라는 테이블을 생성하여 상품들의 상태를 관리하고 있습니다. 'family'를 통해 'categoryId' 값을 받아서 카테고리별로 상태를 관리하고 있는데 문제가 있어서 질문 드립니다.'categoryId' 값에 '0'을 주면, 카테고리와 상관 없이 모든 상품을 볼 수 있는 리스트를 만들 수 있었습니다. 그러나, 이 방법은 상품이 중복되어 나타나는 문제가 발생합니다.모든 상품을 한번에 받아서 필터로 처리하는 방법도 생각해 보았지만, 상품의 수가 너무 많아 이 방법은 효율적이지 않을 것 같습니다.구글링을 통해 정보를 찾아보고 다른 앱 레퍼런스도 찾아보았지만, 원하는 답변을 얻지 못하여 이렇게 글을 남깁니다. 이 문제에 대해 어떻게 해결할 수 있는지 도움을 주시면 감사하겠습니다.감사합니다.

안녕하세요 방금 초급강의에서도 문의 드렸는데 혹시중급강의도 3.10버전에서 호환이 안될까요? ㅠㅠ
