修改gnome-terminal的默认窗口大小

原来打开时为80*24的尺寸，如果需要调整默认的大小，可按下操作：
$> sudo vi /usr/share/vte/termcap/xterm
找到下面这行
:co#80:it#8:li#24\
修改其中的80和24，分别为terminal的高和宽。
也可以用以下命令查看参数：
$> gnome-terminal --help-all

load a track link when window.onunload

When close this window or leave this page will get request below, this trick may be cause bad user experience, and Opera will ignore it:
***.***.***.*** - - [02/Apr/2008:23:10:18 +0800] "GET /track.html?1207149018624 HTTP/1.1" 301 253


<script type="text/javascript">
window.onunload = function(){
 var img = new Image(1,1), i = 0;
 img.src = "http://www.test.com/track.html?" + (new Date()).getTime();
 while(i < 1000000) i++ ; // for img src load
};
</script>

window.onbeforeunload will pop out a confirm dialog, so can't using onbeforeunload.

Translate selection text to chinese in new window

Firefox:
javascript:var dict=function(){var select=document.getSelection();var url='http://sh.dict.cn/search/?q='+select;window.open(url);return ;};dict();

闭包(closures)的写法：(function(){var q=String(window.getSelection());var url='http://sh.dict.cn/search/?q='+q;window.open(url);return;})();

IE7:
javascript:var dict=function(){var select=document.selection.createRange().text;var url='http://sh.dict.cn/search/?q='+select;window.open(url);return ;};dict();

上面function里最后面必须是return; (相当于是return undefined;)否则当前页面会被function return的结果重写，要防止结果重写，也可以将dict()方法调用包含到void操作符内：
void((function(){var q=String(window.getSelection());var url='http://sh.dict.cn/search/?q='+q;window.open(url);return false;})());
usage:
1. 新建一个书签，目标URL用上面的代码，IE会有个提醒，需要确认一下。
2. 在打开的网页里，如GOOGLE READER，要查某个词，选中此词。
3. 点击刚新建的书签(bookmarklet)，IE会再次提醒。

window frames property test

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"
"http://www.w3.org/TR/html4/frameset.dtd">
<HTML>
<HEAD>
<TITLE>A frameset document</TITLE>
</HEAD>
<FRAMESET cols="40%, 60%" name="fs" id="frs">
<FRAME src="fm1.html" frameborder="0" name="fmn1" id="fmi1"/>
<FRAME src="fm2.html" frameborder="0" name="fmn2" id="fmi2"/>
</FRAMESET>
</HTML>

debug under firebug console:
>>> window
Window frames.html
>>> window.frames
Window frames.html
>>> window.frames[0]
Window fm1.html
>>> window.frames[1]
Window fm2.html
>>> window.frames[1].id
# => undefined
>>> window.frames[1].src
# => undefined
>>> window.frames[1].name
"fmn2"
>>> document.getElementById('fmi1')
<frame id="fmi1" name="fmn1" frameborder="0" src="fm1.html">
>>> document.getElementById('fmi1').id
"fmi1"

Object window has name propery, but has no id and src properties, so window.frames[1].src is undefined, we can get src value throught top window's element object, such as cument.getElementById('fmi1').id

Windows cmd 命令行下 SVN 命令执行结果为乱码的解决方法

在系统属性－高级－环境变量[加在当前的用户变量里即可，不一定要全局环境里设置]：
添加一个值：
APR_ICONV_PATH=${subversion_install_dir}\iconv

另同时从网上看到个关于文件提交后显示乱码的问题（未碰到过），也一起写在这里以备所需：
在环境变量中加参数：
LANG=zh_CN.UTF8

window.location and document.location

window.location 和 window.location.herf 为可读写的属性，对此赋值可定向页面去指定的URL。
document.location 和 document.URL 等价，是可只读属性，并且推荐使用document.URL，document.location 已废弃。不过多数浏览器还是可以对document.location 和 document.location.href 赋值定向到新的URL，此做法不推荐使用。
