시내버스노선검색기능구현준비작업

개발 2006/01/04 00:44
대구시내버스 노선 조회 사이트에서 -_-;
여러가지 제약때문에,

버스 정류장 리스트를 쫘악뽑아서
txt파일로 만든다음

이것을 db에 집어넣기위해서
sql 형식으로 바꿔야되는데,

excel, access 로 뻘짓하다가
결국 c++로 parser를 제작 -_-

sql 구문을 손에 넣다 -_-;

java : equals() method overriding

개발/Java 2006/01/01 16:49
msn bot
SBsession 처리 작업도중 ;
이 문제로 몇시간동안 삽질끝에 method overriding으로 해결

class SBField{
       public long SB;
       public int Code;
       
       
       public boolean equals(Object obj){
               SBField f = (SBField)obj;
               
               if(this.SB==f.SB && this.Code == f.Code)
                       return true;
               
               return false;
       }
}


...
...
...

public int find(SBField element){
       
       ListIterator li = list.listIterator();
       
       while(li.hasNext()){
               //System.out.println( li.nextIndex() + ":" + li.next().equals((Object)element) );
               
               Object next = li.next();
               
               //System.out.println(next);
               if(next.equals((Object)element))
                       return li.nextIndex()-1;

       }
       
       return -1;

[펌]rkhunter을 통한 시스템 무결성 체킹하기

리눅스 2005/12/25 17:45

안녕하세요.
http://www.rootman.co.kr 운영자 정찬호입니다.

rkhunter는 rootkit을 찾아 주는 유틸리티로 설치도 간단하고 보는 법도 간단합니다.
또한 중요 파일에 대한 위, 변조를 알려 주어 관리자로 하여금 약간 안도감을 주는^^ 프로그램이죠.

혹시 모르셨던 분들 한 번 써 보세요.
도움이 꼭 되시길 바라면서.

Have a good time !

eclipse 에서 autoftp플러그인사용

개발 2005/12/22 19:23

로컬 프로젝트는 비워둬도 되고,
리모트디렉토리에
절대경로를 적어준다

/home/kfmes/public_html/dboard/

혹시 안되면,
passive 모드 체크!

cvs 사용기

리눅스 2005/12/20 04:27
이번에 msn bot 을 만들기 시작하면서, 소스 관리를 cvs 로 하기로 마음 먹었다. cvs 서버 설정, 계정 설정, 프로젝트 추가 등등 몇시간의 삽질 끝에, 지금은 대략 cvs 사용법을 알게 된것 같다. 한번 써 보니깐 - 정말 편해서 쓰기가 좋다 ㅎ
