john님의 강의를  토대로 사이트를 만들었는데, 상용화를 하기에도 보안적으로 문제가 없는지 궁금합니다. 혹시라도 개인정보 유출 등등이 있을까봐요.. 아니라면 어떤 것에 대해서 더 공부를 해야 할까요??

강좌를 개설해주셔서 정말 감사합니다. ^^ 강좌에서는 master / node *2ea로 구성되어 있는데, master를 etcd를 복제로 구성시 3master로 구성해야 하는 것으로 알고 있습니다. 현재 master / node *2ea 구성에서 master * 3ea/ node *2ea로 구성을 변경할때 도움이 될 정보를 주실 수 있는지요. 부탁드립니다. ^^

안녕하세요! 좋은 강의 덕분에 편하게 JPA를 배우고 있습니다! 실습하면서 한가지 질문이 있는데요! @Entity 객체와 실행하는 메인 클래스의 패키지가 다르니 @Entity를 찾지 못한다고 하는데요. 제목대로 JPA에서 @Entity를 자동으로 찾는 방법이 있는지 궁금합니다. persistence.xml에 Entity를 <class>를 일일히 설정하면 되지만, 일일히 <class>를 지정하지 않고 자동으로 @Entity를 찾을 수 있는 방법을 못찾았습니다.. 혹시 영한님이 알고 계신 방법이 있는지요? (주로 스프링/스프링 부트와 연계하여 사용할 땐 스프링이 packageToScan으로 자동으로 찾아주니 지금 질문이 의미 없을 수 있겠지만 궁금해서요~) 참고: https://stackoverflow.com/questions/1780341/do-i-need-class-elements-in-persistence-xml <property name="hibernate.archive.autodetection" value="class" /> 과거에는 위 옵션이 동작했던 것으로 보이는데 최신 버전에는 동작하지 않더군요..ㅠ

회귀계수보면 분류에 정확도랑다르게 5.453 이런식으로 나와있는데 회귀계수가 어느정도되야 좋은거고 어느정도되야 나쁜건지 궁금합니다

Board클래스에서는 Player _player; 라고 쓰신 후에 이니셜라이즈에서 바로 _player = ~~~라고 하셨는데 Program클래스에서는 Player player = new Player(); 라고 쓰신 후에 Initialize(size, player); 라고 하셨습니다. Program에서 Board처럼 선언했더니 오류가 났습니다. 둘의 차이가 뭔가요? 메인함수가 아니면 Player _player; 처럼 선언할수 있는건가요?

안녕하세요? 강의 듣다가 궁금해져서 질문합니다. 인터넷에서 검색해보니 스테이징 서버가 임시 서버로 해석이 된다고 하더라구요.ㅎㅎ 그러면 스테이징 서버를 만드는게, 실제로 운영하기 직전에 운영서버와 비슷하게 만들어서 테스트? 하는 건가요?  정확하게 잘 몰라서.. 대략 짐작으로 유추해보고 질문 올립니다.  감사합니다.

재귀호출  void my_func(int n); int main() { my_func(1); return 0; } void my_func(int n) { printf("Level %d , address = %p\n", n, &n); if (n < 4) my_func(n + 1); } 이 예제에서  디버거를 찍어보는데 1 2 3 4 순서대로 호출하는거는 이해가 되는데 1. 다시 4 3 2 1 로 돌아오는 이유가 정확하게 이해가 되질않습니다. 2. n의 값이 변할때마다 주소가 달라지는 이유도 정확하게 이해가 되질않습니다.

https://duzi077.tistory.com/198 여기 참고해보세요! android 루트가 아니라 android/app 안의 파일을 수정해주시면 되는 거 같습니다. 원인은 아마... 파이어베이스 패키지가 커서...??

1을 더해주고 로그값을 취한 이유가 무엇인가요?

세션아이디는 처음부터 적어놓으셨던데 마음대로 해도되나요?

Assertions.assertThat(findMember.getId()).isEqualTo(member.getId());Assertions.assertThat(findMember.getUsername()).isEqualTo(member.getUsername());Assertions.assertThat(findMember).isEqualTo(member); junit4 로 정상적으로 설정했으나 자동완성기능에도 나오지 않고임폴트도 되지 않습니다. Cannot resolve method 'assertThat' in 'Assertions'라고 나옵니다.

nodejs에 req.params.id가 요청이 id값이면 req.params.id를 쓸수가있잖아요? 하지만 url이 req.params.id가 아닌 경우에 id값을 얻고싶으면 어떻게 해야하나요?  강의에서는 '/' get에서 댓글을 잘 했지만 ejs 템플릿엔진으로 '/'에 게시물을 만들고 거기에 댓글을 하려니 어떻게 클라이언트에 댓글을 뿌려야할지 잘 모르겠네요.

안녕하세요. 좋은 강의 잘 듣고 있습니다. 강의를 듣는중에 개선점을 바로 제안드립니다. 더 좋은 강의를 만들고 다음번 수강생에게 더 많은 도움을 주고자 제안드려요 1. 화질- 화면 화질이 너무 않좋아서 글씨를 알아보기 힘들때가 많습니다. 코딩에서 글자가 흐릿하니 정말 답답합니다. 다른강의도 듣고 왔는데, 그기는 화질이 아주 또렸했는데, 유독 이 강의는 화질이 나빠서 조금 답답하네요.. 다음번에는 이점이 개선되면 좋겠습니다. 2. 자판소리- 기계식자판을 사용하시는지 자판소리가 너무 심하게 들려서 강의듣는 입장에서 아주 거슬립니다. 수업에 집중도를 흩트리는것 같습니다. 다음에 강의에서는 이점도 개선되었으면 합니다. 감사합니다. 수강생중 1명이
