some tips for running RUBiS

1. The correct location for appropriate rubis.properties that is necessary to configure RUBiS
/RUBiS/RUBiS/Client/build/RUBiS-1.0

2. Order of running applications
Database server (mySQL) -> JOnAS -> Apache -> then type 'ant emulator' at RUBiS directory

3. to configure connectors between JOnAS and Apache
in JOnAS side : server.xml
in Apache side : workers.properties of mod_jk.so

4. When Apache is working but JonAS is not working properly
- check server.xml

5. for mod_jk connection : usually server port is 8009

American Health Care System on PBS

http://www.pbs.org/wgbh/pages/frontline/sickaroundtheworld/

마이클 무어 같은 좌파성향의 사람의 다큐멘터리도 아니고, 미국 정부의 지원을 받는 미국 공영방송국에서 만든 리포트 프로그램에서 다룬 미국의 health care. 한국의 의료제도만 겪어본 분은 이 사람들이 자기네 시스템이 좋다고 말하는 부분이 왜 좋은지 이해가 되질 않을 것이다. 왜냐면 대부분 한국과 비슷하니까. 반면, 여기나오는 점들이 대부분 미국에서는 이루어지지 않는 것들이다.

미국의 민영 의료제도는

1. 효율적이지도
2. 저렴하지도
3. 시민들의 건강에 도움이 되지도

않는 시스템임에 틀림이 없다.

반면, 한국의 의료보험에 대해서 의사가 아닌 사람들에게 문제가 있냐고 물어보면, 과연 문제가 있다고 말하는 사람이 얼마나 있을까? 공급자인 의사나 의사협회의 의견과는 전혀 딴판이다.

의료보험이 의사와 병원을 위한 것인지 환자를 위한 것인지를 생각해보면 어느쪽이 문제가 있다고 생각할 때 고쳐야하는 건지의 기준이 좀 더 잘 서지 않을까 싶다.

China on the frontline of PBS

http://www.pbs.org/wgbh/pages/frontline/youngchina/

우리과에도 중국학생들이 많은데, 어렴풋하게 단편적으로만 듣던 중국이란 나라의 현실에 대해서 꽤 잘 다룬 것 같다.

카메라 개시

 


수억들여...하나 장만했다.

Nikon D60.

장보러 가면서 연신 찍어보고, 장보고 와서 집 주변을 어슬렁거리며 또 연신 찍었다.

Under Pressure - Queen and David Bowie



뭔가 잘 안풀리고, 압박받는다 느낄 때...

Under Pressure

Mm ba ba de
Um bum ba de
Um bu bu bum da de
Pressure pushing down on me
Pressing down on you no man ask for
Under pressure - that burns a building down
Splits a family in two
Puts people on streets
Um ba ba be
Um ba ba be
De day da
Ee day da - that's o.k.
It's the terror of knowing
What the world is about
Watching some good friends
Screaming 'Let me out'
Pray tomorrow - gets me higher
Pressure on people - people on streets
Day day de mm hm
Da da da ba ba
O.k.
Chippin' around - kick my brains around the floor
These are the days it never rains but it pours
Ee do ba be
Ee da ba ba ba
Um bo bo
Be lap
People on streets - ee da de da de
People on streets - ee da de da de da de da
It's the terror of knowing
What this world is about
Watching some good friends
Screaming 'Let me out'
Pray tomorrow - gets me higher high high
Pressure on people - people on streets
Turned away from it all like a blind man
Sat on a fence but it don't work
Keep coming up with love
but it's so slashed and torn
Why - why - why ?
Love love love love love
Insanity laughs under pressure we're cracking
Can't we give ourselves one more chance
Why can't we give love that one more chance
Why can't we give love give love give love give love
give love give love give love give love give love
'Cause love's such an old fashioned word
And love dares you to care for
The people on the edge of the night
And loves dares you to change our way of
Caring about ourselves
This is our last dance
This is our last dance
This is ourselves
Under pressure
Under pressure
Pressure

RUBiS on my PC

집의 PC에서 cygwin위에다가 open source 프로그램들 - apache, JOnAS, mySQL을 좀 돌려보려고 하는데, 잘 될련지 모르겠다. 일단 apache는 설치했는데, jk_mod를 어떻게 설치해야하는지가 좀 쉽지가 않은거 같다. 설치가 진행되는데로 tip을 여기다 올리고, 마지막에 RUBiS까지 실행시키는걸 목표로..

----------------------

작업하다 보니 JOnAS와 Tomcat 커넥터가 Java VM이라 windows용 binary를 깔아야 한다는 사실을 발견. 갑자기 재미가 없어지려 한다.

cygwin에서 한글을 보고 싶어요

그동안 xterm을 사용했더니 뭔가 system error message같은 것들이 종종 한글로 출력되서 답답했는데, rxvt를 사용했더니 한글이 나온다. 한글을 보고 싶으면

rxvt -km kr

을 하시면 됩니다.

cygwin에서 apache2돌리기

1. 설치
cygwin setup을 이용하여 apache2를 다운받는다.
다운로드 받으면 httpd.conf는 /etc/apache2
httpd2.exe및 httpd2.exe의 실행 스크립트인 apachectl2는 /usr/sbin
일부 기본 화일들은 /usr/share/apache2
실행 모듈들은 /usr/lib/apache2 에 설치가 됩니다.

2. 실행전
/usr/sbin에 PATH설정이 안되어 있는 경우 shell resource에 PATH=/usr/sbin:$PATH 를 추가해줍니다.
apache2는 cygwin에서 cyrserver를 이용하여 IPC를 사용하므로 cyrserver를 미리 실행해주어야 합니다.
아래 두 줄을 타이핑 해주면 됩니다.

cygserver-config
net start cygserver
그리고, 환경변수에 CYGWIN=server가 있어야 하므로 export CYGWIN=server를 해야 합니다.
환경변수를 설정하기 싫으시다면 아래와 같은 요령으로 하시면 됩니다.
cygrunsrv -I foo -p /usr/sbin/foo -e "CYGWIN=server"


3. 실행
이제 실행하면 됩니다.
apachectl2 start

6 Ways You're Wasting Gas


6 Ways You're Wasting Gas


Provided by CNNMoney.

In summary,

1. Racing away from green lights
When the light turns green, you don't have to take off as quickly as possible.

2. Racing up to red lights
When you're driving down the street, and you see a light red light or stop sign up ahead, you should lay off the gas sooner rather than later.

By themselves, these first two tips can improve your fuel economy around town by as much as 35 percent, according to tests conducted by automotive information Web site Edmunds.com

3. Confusing the highway with a speedway
In tests by Consumer Reports, driving at 75 miles per hour instead of 65 miles per hour reduced fuel economy by between 3 and 5 miles per gallon, depending on the vehicle.


4. Bumper-buzzing
Tailgating wastes gas. Every time the driver ahead taps his brakes, you have to slow down even more than he did. (That's because you can't react immediately so you have to slow even more because you're slowing down later.) Then you accelerate again to get back up to speed and resume your bumper-buzzing routine.


5. Driving standing still
You've probably heard that it takes more gas to restart a car than to let it run. Maybe that used to be true, but it isn't anymore. With modern fuel-injection engines, it takes very little extra gas to restart a car once it's warmed up. Idling, meanwhile, burns about a half-mile worth of gas every minute, according to the California Energy Commission.


6. Short hops
Go to your farthest destination first so your engine has a chance to reach its optimal operating temperature. Then make your other stops on the way back. With the engine warmed up, the car will restart easily and run efficiently all the way home.

Alan Parsons Project - I Wouldn't Want To Be Like You (1977)



노래도 재미있지만, 비디오 초반부에 나오는 컴퓨터들이 인상적이지요. 77년에 저런 장비를 촬영하려면 어디로 가야 했을까. Dot printer로 프린팅한 I Robot 문구도 참..

30년만에 컴퓨터가 정말 많이 발전했다는 생각이 듭니다.

Twisted Sister - We're not gonna take it



요새 무슨 선전에 이 노래가 자주 나와서 유튜브 검색..

WE'RE NOT GONNA TAKE IT

This is our life, this is our song
We'll fight the powers that be just, don't pick our destiny'cause
You don't know us, you don't belong

REPEAT CHORUS

Oh, you're so condescending, your gall is never ending
We don't want nothin', not a thing, from you
Your life is trite and jaded, boring and confiscated
If that's your best, your best won't do

RELEASE:

Oh
Oh
We're right, yeah
We're free, yeah
We'll fight, yeah
You'll see, yeah

REPEAT CHORUS (2x)

No way
