日月昭昭,唯我大明——明代国旗
关于日月旗最早的由来是元末明初反抗当时统治者的人民在中秋节日悬挂来表示反元的标志。这种日月旗就是后来明朝国旗。
日月旗是明朝的国旗，由明朝的国号“明”字的意义演化而来，明朝最初没有国旗，隆庆开关以后，由于对外贸易的迅速发展，明朝船只按照国际上的标准悬挂了一种旗帜以区别于葡萄牙、荷兰等国船只的国旗，成为当时事实上的中国国旗。近年来，南洋一些明代船只被打捞，这种旗帜也重新面世。
日月旗的象征和含义：
这面旗叫日月旗。中间的黄色象征月亮，后面的光芒象征太阳，偏紫的蓝色的天象徵开放的明朝。
取日月重叠之意义(日在后，月在前) 日月即是明。
旗帜由红日、黄月重叠的图案和蓝底组成。蓝底代表青天，象征着我大汉民族光明磊落、崇高伟大的人格和志气。
日月重叠即是“明”字，代表大明，位于旗帜的正中不偏不倚，是取中国位于四方之中之意。
旗帜中央的黄色又代表着汉人的肤色，象征着大明是汉族人建立和统治的国家，黄色位于中央，意指大明将汉族的利益视为核心利益。
红色的光芒是太阳的光芒，又象征大明属于火德，亦指统治大明的朱姓皇族。十二道光芒即指一天十二个时辰，一年十二个月，光芒位于青天之上，表示大明光辉时刻都在普照万方。
红色光芒中四个尖锐的大角，分指上下左右四个方向，即“际天极地，罔不臣妾”之意，又表示着礼义廉耻，国之四维，是大明世代遵守的道德规范。
中国道教的象征是阴阳图，“阴阳”去掉“β”就是“日月”
这面旗帜无疑是设计非常到位的，让人可以无穷联想。
日月旗的演进
日月旗使用之初，底色采用玄色，图案为正方形，因为玄色自古以来是象征汉族的颜色。但因为玄色太暗不易看清，故改为蓝色。后来又根据国际惯例，将旗帜的形状改为大多数国家通行的长方形，成为我们现在见到的样子。
日月旗的使用
以反清复明为宗旨的洪门，曾经使用过日月旗，反抗清廷。洪门中有《大明旗诗》云：“日月旗中第一枝，会合洪英创洪基。为人须要存忠义，不可外头说是非。”

IE6-7-8 无法显示CMYK模式JPEG图片的问题
由于CMYK模式保存的JPEG图片无法在IE6，IE7，IE8中显示，需要做转码处理
但是在目前非IE核心浏览器如 firefox chrome 可以打开
这是因为IE6，IE7，IE8不支持CMYK模式的jpeg图片
而非IE核心的可以正常打开浏览
其实解决这个问题很简单，
可以在用photoshop打开图片，在窗口会显示图片名和模式，依次点击菜单栏——图像——RGB模式就行了，
然后保存替换，重新上传到服务器也可以。用acdsee 转换也是可以。
geek们可以用convert加一个 -colorspace RGB 参数就可以解决这个问题，原因去翻文档吧。。。
这里附上2张图
RGB：
CMYK:
如何找出目录里面有的CMYK模式的图片，可以试试下面这个脚本：
此脚本需要imagemagick库支持
#!/bin/bash
if [ ! -d "$1" ]
then
echo "Script to look for JPEG files in the CMYK colorspace."
echo "Usage: $0 directory"
exit 1
fi
find "$1" -type f | while read filename
do
filetype=$(file -b "$filename" |awk '{print $1}')
if [ $filetype == 'JPEG' ]
then
colorspace=$(identify -verbose "$filename" |grep " Colorspace:" |awk '{print $2}')
if [ $colorspace == 'CMYK' ]
then
echo "$filename"
fi
fi
done
在python中如何判断CMYK
用PiL来判断
debian下安装PiL：
sudo apt-get install python-imaging
import Image
im = Image.open('./test/CMYK.jpg')
print im.mode
squid 日志统计–请求域名的排序
##日志为combined模式
cat /usr/local/squid/var/logs/access.log |awk '{print $7}'|awk -F '/' '{print $3}'|sort| uniq -c| sort -k 1 -n -r

debian6上安装lnmp平台
最近要为监控系统写点php页面，所以开始现学php，当然要建立一个php的开发环境了，
系统当然选择debian了，重新在vbox里面装了虚拟机debian6，新的vbox4.1.6 支持了图形界面的端口转发，设置端口转发更方便了
步骤是 选择虚机，设置，网络，点击Port Forwording 设置几个，比vbox3.0 用命令设置方便多了。
debian6上安装lnmp平台
1.安装nginx：
下载nginx：
安装nginx：
cd nginx-1.1.8/ ./configure --prefix=/usr/local/nginx --with-http_realip_module --with-http_sub_module --with-http_flv_module --with-http_dav_module --with-http_gzip_static_module --with-http_stub_status_module make install make cd ../
3.安装mysql
mysql 还是不编译算了
直接apt-get
apt-get install mysql-server
3.安装php：
php-fpm已经被php收编
在最新的php5.3版本中就可以使用了
wget http://cn2.php.net/distributions/php-5.3.7.tar.gz tar zxvf php-5.3.7.tar.gz cd php-5.3.7/ ./buildconf --force
先查看autoconf版本够不？
apt-get install autoconf2.13
再安装一些依赖关系：
apt-get install libxslt1-dev libmcrypt-dev aptitude install libtidy-dev curl libcurl4-openssl-dev libcurl3 libcurl3-gnutls zlib1g zlib1g-dev libxslt1-dev libzip-dev libzip1 libxml2 libsnmp-base libsnmp15 libxml2-dev libsnmp-dev libjpeg62 libjpeg62-dev libpng12-0 libpng12-dev zlib1g zlib1g-dev libfreetype6 libfreetype6-dev libbz2-dev libxpm-dev libmcrypt-dev libmcrypt4 sqlite3 bzip2 build-essential libreadline5-dev libedit-dev ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-config-file-scan-dir=/usr/local/php/etc/conf.d --enable-fpm --with-curl --with-pear --with-gd --with-jpeg-dir --with-png-dir --with-zlib --with-xpm-dir --with-freetype-dir --with-mcrypt --with-mhash --with-mysql --with-mysqli --with-pdo-mysql --with-openssl --with-xmlrpc --with-xsl --with-bz2 --with-gettext --disable-debug --enable-fpm --enable-exif --enable-wddx --enable-zip --enable-bcmath --enable-calendar --enable-ftp --enable-mbstring --enable-soap --enable-sockets --enable-sqlite-utf8 --enable-shmop --enable-dba --enable-sysvsem --enable-sysvshm --enable-sysvmsg make make test make install cp php.ini-production /usr/local/php/etc/ cp php.ini-production /usr/local/php/etc/php.ini
4.配置php 和php-fpm

配置nginx：

error_log logs/error.log info;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;
keepalive_timeout 65;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
gzip on;
server {
listen 80;
server_name localhost;
location / {
root /path/to/dev/php_dev;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /path/to/dev/php_dev$fastcgi_script_name;
include fastcgi_params;
}
}
}
在/path/to/dev/php_dev下
编辑phpinfo.php
<?php
phpinfo();
?>
浏览器测试。。。。。。
debian 设置vi为crontab的默认编辑器
debian中设置vi为crontab的默认编辑器，debian中原本默认编辑器是nano，这个nano是个很残的编辑器，
只需要下面的命令，然后选择vim.basic 即可（debian5.x debian6.x 中实验通过）：
xu:~# update-alternatives --config editor
There are 4 alternatives which provide `editor'.
Selection Alternative
-----------------------------------------------
1 /bin/ed
*+ 2 /bin/nano
3 /usr/bin/vim.tiny
4 /usr/bin/vim.basic
Press enter to keep the default[*], or type selection number: 4
用xen-center安装debian
用xen-center安装debian
用xen-center安装debian太搞人了
试了debian的3种iso文件 都不行
最后试了网络安装 最后终于成功
debian初始安装没有killall命令？
debian初始安装没有killall命令？
今天用xen-center安装了 一枚debian-lenny用作公司网站网页加载测试（基于python pyqt webkit）
进入系统发现没有killall命令
search 一下发现：
pageload:~# apt-cache search killall
psmisc – Utilities that use the proc filesystem
sysvinit-utils – System-V-like utilities
应该是psmisc
pageload:~# apt-get install psmisc
bingo 搞定.
