solve winlogon.exe memory leak
keywords: windows xp, winlogon.exe memory leak
delete this reg key, and the problem is solved:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify\psfus
you could compare your setting with other normal systems, and delete those unique keys.

get Last-Modified in jQuery ajax.
This issue bugged me for days. After a deep inspect of jQuery source code, I worked out this code:
$url="../status.php";
$.ajax({
"url":$url,
"type":"GET",
"complete":function(xhr, s){
handleResponse(xhr, s);
}
});
function handleResponse(xhr, status){
$("#result").append("
Headers:
"+xhr.getAllResponseHeaders());
var $dateStr = xhr.getResponseHeader("Date");
alert(xhr.responseText);
alert($dateStr);
var $date = new Date($dateStr);
alert($date);
}
<div id="result"></div>
===================
If you think this is useful, please leave a word, many thanks.

Why unbind of jQuery does not work
I need a javascript function to unbind "onclick" operation for some div elements like this:
and then click and unbind:
This code cannot unbind the onclick event, it seems that the unbind could only unbind the events binded by jQuery, not events coded directly in HTML.
I hope you can understand this.

Another usage of 7-zip
7-zip can open chm file, and unpack files in it.
That is wonderful, because some old chm file does not work fine in modern system,
7-zip could get what we want instead of bad chm files.

"You are welcomed" or "you are welcome"?
From:
http://answers.yahoo.com/question/index?qid=20060628170518AAJhSop
Is it correct to say "you are welcomed" or "you are welcome"?
I have said "you are welcomed" my whole life, and decided to switch to "you are welcome" a week ago. But something is bothering me, so I come to you for advice.
Serious answers only.
Answer only if you are at least 90% certain.
==============================================
The two phrases have different meanings.
The proper phrase, "You are welcome" says that the person is welcome to whatever you have given them.
The other phrase, "You are welcomed", which is not generally used, implies that the person is being welcomed to wherever they are, as in "we are welcoming you into this place". Notice that the sentence does not say who is doing the welcoming, only who is receiving the welcome. It's an awkward phrase and should not be used, even when you are truly welcoming someone to a particular place.
So, when someone thanks you, just say "you're welcome" and if you want to welcome them to some place, then say "welcome to my ..."

Fix one RealVNC viewer problem.
I cannot connect to RealVNC server yesterday, the same today.
I did it on another PC. So the problem is in viewer, not in server.
Open regedit, find this:
HKEY_CURRENT_USER\Software\RealVNC\VNCViewer4\KnownHosts
and delete the server and reconnect, the viewer will generate a new secure key,
and then all is OK.

STX Transform Notes
I tries to transform xml with Joost(STX), but I found that sometimes the child nodes cannot be matched and transformed.
Finally I found the problem was tied with the XML namespace, and made the transform working in this way, please notice the prefix "myns" both in root node and child nodes:
Source XML:
<RootNode xmlns="http://.... " >
<ChildNode>
....
STX:
<stx:transform version="1.0"
xmlns:stx="http://stx.sourceforge.net/2002/ns"
xmlns:myns="http://www.../" >
<stx:template match="myns:RootNode">
...
<stx:template>
<stx:template match="myns:ChildNode">
...
<stx:template>

How to output new line in result xml in STX transform
I'm new to professional xml develop and boring the transformed result xml is always one large line those days.
Now I found the way out,
"<stx:text>&# xA;</stx:text>" is the solution!
(please remove the white space, google can not post xml code?)

发现 Foxmail 的一个逻辑 BUG
今天网络情况不咋样, 开个网页经常打不开.
用 Foxmail 一直收不到信.
没有设置让foxmail记住密码.
一旦网络坏掉而没有成功收信, 下次收信时, foxmail会再次询问密码.
我认为这是一个很严重的逻辑问题, 应该在密码错误的情况下才应该询问密码, 而不是在网络出错的情况下.
