선생님의 영상을 따라하는 도중에  파이어베이스 문서에서 기존 회원가입을 통한 인증하기가 아닌 구글 또는 페이스북을 이용해 인증하는 방법도 있던데 혹시 그 방법으로 인증하는 영상또는 방법을 자세하게 알려주실수 있나요??

안녕하세요 맛비님. 유튜브랑 강의 잘 챙겨보고 있는 비메모리 설계 꿈나무 4학년 학생 입니다. 조금 주제를 벗어난 질문 일지 모르지만 강의나 유튜브에서도 가끔 언급을 하시는 C 언어 실력 관련한 질문입니다 ㅎㅎ;;   현재 저는 C++ 문법정도만 유튜브 강의를 통해 학습한 상태인데, 맛비님이 설계를 잘 하기 위해서는 C 도 필수로 하셔야 한다고 해서 걱정이 됩니다. C로 뭘 만들어본 경험이 하나도 없어서요 .. 시간이 있어서 미리 공부를 차근차근 해놓으려고 하는데, 이 상황에서 어떤 방향성을 가지고 공부하면 좋을까요?(베릴로그는 따로 공부중입니다.) 간단하게 라도 조언 해주시면 큰 도움이 될 것 같습니다 !! 예를들어 백준 알고리즘 문제를 풀어봐라, 어떤 종류의 강의를 한번 들어봐라 이런식으로 라도 짧게 대답해주셔도 됩니다!!

질문: 생성자에서 Autowired 처리가 제대로 안되는지 policyMap과 policies 출력해보면 빈걸로 나오네요 어떻게해야 되나요?? 출력 코드     AllBeanTest   AutoAppConifg   RateDiscountPolicy   FixDiscountPolicy DiscountPolicy

For Each 시트시, 시트라는 변수를 선언 해주지않았는데 시스템에서 인식을 하는 이유가 있나요?   기본적으로 시트라는 것이 엑셀파일에 포함이 되어있는건지 아니면 저희에게는 보이지 않지만 미리 선언이 되어있는건지 알고싶습니다

// 화이트 리스트의 경우 인증 체크private boolean isLoginCheckPath(String requestURI) { return !PatternMatchUtils.simpleMatch(whiteList, requestURI);} 이 부분에서 왜 그냥 리턴하지 않고 !를 붙여서 반대값을 리턴하는지 잘 이해가 되질 않네요   답변 부탁드립니다.

@app.route('/json_test') def hello_json():     data = {'name' : '김대리', 'family' : 'Byun'}     return jsonify(data) 실행후  {"family":"Byun","name":"\uae40\ub300\ub9ac"} 출력됩니다. 사전의 키 name과 family 순서가 바뀌고 name의 한글이 깨지는데.. 원인과 해결 방법을 설명 부탁드립니다. 참고로 /server_info는 아래 처럼 잘 실행 됩니다.  {"server_name":"0.0.0.0","server_port":"8081"}

안녕하세요 로드맵 강의를 듣고 있는 학생입니다.   slack 요청을 보내드렸는데, 확인하시면 승인 좀 부탁드리겠습니다.   항상 좋은 강의 감사합니다!

TCP는 데이터 경계가 없어 부분적으로 오는 경우를 고려해준다고 설명해주셨는데  그 외적으로 패킷 분실,  패킷 손상,  도착 순서 등등은  TCP에서 보장해주기 때문에 서버코어단을 만들때 고려해주지 않아도 되는 게  맞을까요?? 

  큰 기업이라면 sql 서버에 지속적으로 데이터를 요청하는것보다 그냥 c나 c++로 custom db를 사내에 만들어서 관리하는것이 (기능은 더 적더라도) 노력은 들지만 한번 만들어 놓으면 더 빠르고 관리하기 편할 것 같다는 생각이 드는데  실제 현업에서 이러한 사례가 있는지, 없다면 이유가 있나요? (그냥 구현하기가 그만큼 어려워서인가요?) 자체적으로 게임엔진을 만드는 회사들도 있는데 자체 db를 만드는 회사는 없나 갑자기 궁금해져서 여쭤봅니다.
