서버개발로 합격을 해서 2월에 출근예정입니다. 취업전엔 취업이 될까가 걱정이었는데 취업을 하고나니 저 같은게 월급을 받아도 될까가 너무 걱정됩니다. 힘들게 들어간 회사인 만큼 수습탈락하기 싫고 업계에서 롱런하고 싶은데 회사생활을 잘하고 커리어를 잘쌓는 부분에 대해 간단한 팁이라도 주실수 있나요?   PS. 항상 좋은 강의 감사합니다. 앞으로도 있을 좋을 강의들도 기대됩니다 ㅎㅎ

안녕하세요. 노션에서 다크모드로 설정 후 웹에서 공유로 링크복사하여 들어갈 경우 다크모드가 아니라 라이트모드로 나옵니다. 이 부분은 외부로 설정 시 다크모드로 변환이 안되는것인가요?

강의 시간에 다룬 내용인 복리 문제입니다.이해가 가지 않는 부분이 있어서 댓글 남깁니다. 아시는 분이 계신다면 답변 부탁드립니다. 위 사진은 강사님께서 하신 방법 그대로를 따라서 작성한 코드이고 이 사진은 제 궁금증입니다."fund에 seed_money를 넣고 반복문에 fund를 사용 할 거라면 그냥 처음부터 fund 선언을 하지 않고 바로 seed_money를 사용하면 안 되나?" 가 제 의문입니다. 제 방식 대로 했더니 올바른 답도 나와서요. 강사님께서는 보는 사람이 코드를 더 정확하게 이해할 수 있게  만들기 위해 fund 변수를 넣으셔서 짠건가요?

명령 프롬프트 cd Desk top 입력하니까 저장된 경로를 찾을 수 없다고 뜨는데 왜 그러는 건가요?

안녕하세요~ C# 강의 듣고 있는데 제가 설치한 2022 VISUAL STUDIO는 // See https://aka.ms/new-console-template for more information int hp = 100; int level = 50; bool isAlive = (hp > 100); bool isHighLevel = (level >= 40); 이런식으로 써지는데요.   강사님께서 맨처음 C#을 켜시면    using System; { class Program { static void Main(string[] args)  이렇게 시작하더라구요ㅠㅠ 제 버전에서는 약간 다르고 저 위의 코드로 실행을 했을 때 코드가 없다고 떠서 어떻게 해야할지 모르겠습니다ㅜ

여러분들~ 열공하시느라 수고가 많으십니다. 이거 보시는 분들 중 강의를 보시다보면 새로고침한다고 새탭을 켰다가 끄는 것을 보실 수 있는데.. 그냥 F5 눌르십셔. -끝-

정점 3개의 컬러가 보간되어서 픽셀 셰이더의 input에 들어가는거는 이해했는데, 그럼 이 때 Color 외에도 Lighting 수업에서 Pixel Shader에 넘겨주셨던 viewPos, viewNormal같은 것들도 정점 3개의 비율에 따라 보간되어서 들어가나요? 약간 이런 느낌으로 이해하고 있는데, 정확한지 여쭤보고 싶습니다. 따로 MS 자료를 찾아봤는데 정확한 문서를 찾지 못해서 질문드립니다.

int hp = 100; Console.WriteLine(hp++);   bool b = hp < 100;   이렇게 프로그래밍하면, 100이 나오는데 false가 안나오고요 .. 어떻게 해야할까요? 

Error running 'Unnamed': Argument for @NotNull parameter 'mainClassName' of com/intellij/execution/util/JavaParametersUtil.isClassInProductionSources must not be null Run을 하려고 하는데 이런 오류가 나오는데 해결 방법이 어떻게 되나요?!

testbench에서 if의 조건문에서 !== 의 연산자를 사용해주셨는데 !== 보통 잘 사용하지 않는 걸로 권장하는 걸로 알고 있습니다! 왜 굳이 != 말고 !==을 사용하셨는지 궁금합니다!

안녕하세요. 우선 좋은 강의 제공해주셔서 감사합니다.   ResourceQuota 에서 ns 외에도 cluster 전체 단위로 권한을 부여 하려면, 1. 어느 오브젝트에다가 설정을 해줘야하는지, 2. 클러스터 전체 단위로 리소스를 제한하는 경우가 어떤 케이스가 있는지(네임스페이스 단위로 분리해서 쓰는 경우가 아닐 것 같아서..) 여쭤봐도 될까요? 뭔가 하나의 클러스터를 구성해서 쓰는데, 이 클러스터에서 사용 할 수 있는 컴퓨팅 자원을 한 번 더 제한해서 쓰는 케이스에 대해서 궁금합니다.(+어떻게 지원하는지) 감사합니다.   -  https://kubernetes.io/ko/docs/concepts/policy/resource-quotas/

1. 영상 15분경, mainactivity에서 putExtra("data", "1..9") 설정 후  imageinsideactivity에서 getStringExtra("data")를 설정만 했는데도, 사진을 눌렀을때 value 값을 알아서 반환하여 toasting했습니다. 이 부분 이해가 잘 안돼서 그런데 설명 부탁드리겠씁니다.   2. R.layout / R.drawable 할때 R의 개념을 설명 부탁드리겠습니다.   3. activity_image_inside.xml에서  <ImageView android:id="@+id/memberImageArea" android:src="@drawable/member_1" android:layout_width="match_parent" android:layout_height="match_parent"/> src는 분명 사진 member_1이었는데,  setImageResource의 함수로 인해서 사진들이 바뀐것 같은데, 개념설명 부탁드리겠습니다~!
