safari网站全屏

Albert — Mon, 16 Jan 2012 09:16:19 +0000

用户需要在Safari手动将网站添加到主屏幕后才能够实现网站全屏。具体方式是在里面添加如下内容：

您可能已经知道这-但你可以摆脱地址栏 with:document.body.onload = function(){setTimeout(“window.scrollTo(0,1);”,100) ；} ；

要创建一个本机应用程序更的假象，你可以禁用滚动：document.body.ontouchmove =功能（E）{e.preventDefault ();};

solr tomcat utf8搜索乱码

Albert — Sat, 17 Dec 2011 05:07:31 +0000

connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8" />

加了URIEncoding=”UTF-8″ 就好了。。

Segmentation fault php debug

Albert — Fri, 09 Dec 2011 05:49:59 +0000

调试个脚本程序，总是报这个，烦死我了
echo core > /proc/sys/kernel/core_pattern
ulimit -c unlimited

继续执行脚本
Segmentation fault (core dumped)

找到core文件
gdb /usr/local/php/bin/php core.1725

Program terminated with signal 11, Segmentation fault.
#0 0x000000000070bcd2 in gc_zval_possible_root (zv=0xfb0cec0) at /root/install/php-5.3.8/Zend/zend_gc.c:143

大体知道怎么回事。。

org.apache.solr.common.SolrException: Error loading class ‘solr.VelocityResponseWriter’ at org.apache.solr.core.SolrResourceLoader.findClass

Albert — Tue, 06 Dec 2011 09:29:40 +0000

solr 3.1 安装多个core的时候由于在example里面加了一级目录，所以全部报错！
org.apache.solr.common.SolrException: Error loading class ‘solr.VelocityResponseWriter’ at org.apache.solr.core.SolrResourceLoader.findClass

在core0/conf/solrconfig.xml里面

前面要多加一层../
加完了还是不好用，我干脆给他disable吧。。

关了这个，最后好了。。nnd..

mmseg4j solr 3.1安装

Albert — Tue, 06 Dec 2011 05:34:42 +0000

http://code.google.com/p/mmseg4j/

下载最新版本
unzip 到mm目录
cp data /usr/local/solr/example/solr/data
cp dist /usr/local/solr/example/dist
cp mmseg4j-all-1.8.5.jar /usr/local/tomcat/webapp/solr/lib/
可能需要mkdir lib这个目录
SEVERE: org.apache.solr.common.SolrException: Error loading class ‘com.chenlb.mmseg4j.solr.MMSegTokenizerFactory’

应该是lib放错了位置
放到solr_home中就好了
放到/usr/local/solr/example/solr/lib(lib要建立）
然后重启，就好了

给入array(数组)搜寻键值，将其unset

php.ini不能被识别

Albert — Thu, 24 Nov 2011 02:53:53 +0000

phpinfo()里面打出的php.ini路径下有php.ini但是load里面是空
查看php-fpm的用户，chown php.ini用户 chmod php.ini 重启php-fpm 搞定。。

这个问题很奇怪，改完了以后，还是有的时候好有的时候坏了，头疼

php指令行上，可以使用php -c /usr/local/etc/php.ini 来代替之前的php指令
我还修改了/usr/bin/php-fpm (或者你的启动脚本在service里面）

php_opts=”–fpm-config $php_fpm_CONF -c /usr/local/etc/php.ini”

nginx 复杂逻辑配置思路

Albert — Thu, 17 Nov 2011 07:48:19 +0000

map $remote_addr $whiteList {
default 1;
182.151.205.165 0;
119.6.97.141 0;
}
set_from_accept_language $lang en ja ru it fr de es zh;
set $accLang 0$whiteList;
if ( $lang = ‘zh’ ) {
set $accLang 1$whiteList;
}
if ( $country != ‘CN’) {
set $accLang 0$accLang;
}
if ( $country = ‘CN’) {
set $accLang 1$accLang;
}
set $allowNow 0;
if ( $accLang ~ “^(.+)0$”) {
set $allowNow 1;
}
if ( $accLang = “001″) {
set $allowNow 1;
}
总的来说就是将多个条件结果拼接成010的串，然后通过正则来匹配符合条件，最终得出0或者1，这么写代码很傻，不过哦好歹我实现了：）

利用nginx user 模块进行A/B test

Albert — Sun, 13 Nov 2011 11:15:24 +0000

userid on;

userid_domain milanoo.com;

set $serp $2;
set $uid $1$2$3;

if ( $uid_got ~ “^uid=(.{9})(.)(.+)$” ) {
set $serp $2;
set $uid $1$2$3;
}
set $fa A;
if ( $serp ~ “(A|B|C|D)” ) {
set $fa B;
}
##这个也可以出C方案D方案，就和 $serp分吧，但是必须是1/16的。。
log_format main ‘$uid_got – $serp – $uid_set’; //debug Log
access_log logs/php.log main; //debug//
#####要想做a/b test对$serp进行正则即可。。###
fastcgi_pass 127.0.0.1:9000;
fastcgi_param FA $fa #将方案号传递给php $_SERVER['FA']
fastcgi_param UID $uid; #传递给php $_SERVER['UID']
