SpAcDaemon Virus
Today I was kind of doing some house keeping job on my computer.
To my supprise, when I went to My Computer -> System Properties,
I was looking at a picture of Bart Simpson and some weird info
like this:
Manufactured and supported by:
SPAC
thespacdude@yahoo.com
and when I clicked on Support Information, it shows:
SPAC
ERROR: Water detected in the BIOS.
Something wonderful has happened,
your computer is alive......
I googled it, I also tried McFee, Symantec, MS AntiSpyware, Adware, SpyBot, F-Secure, etc.
But none would detect any virus or trojans in my computer.
There're 2 strange behavior on my computer recently.
1. At Windows Startup, it plays some weird sound... you hear someone laughing.
2. It changed my OEM information, so I saw "Manufactured and supported by: SPAC"
After about 3 hours of digging thru my registry and system files, I found it.
The file is c:\windows\mssreprc.exe
also it creates a registry key
Name:SpAcDaemon Value: C:\WINDOWS\mssreprc.exe
under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
It changed my C:\WINDOWS\system32\OEMINFO.INI to the following:
[general]
Manufacturer=SPAC
Model=thespacdude@yahoo.com
[Support Information]
Line1= ERROR: Water detected in the BIOS.
Line2=
Line3= Something wonderful has happened,
Line4= your computer is alive......

Big5中由於設計上的疏失，導致一些屬於控制字元的資料容易引起一些程式環境的誤判。造成顯示出來的中文字不是我們想要的結果。所以我們在寫程式的時候對於中文的處理要特別小心。下面列出了一些容易引發衝碼的文字，寫程式的人，最好都能夠測試下面的字在你的程式中可以正確無誤的被使用。

How to run a piece of JavaScript code after a certain timed delay?
This allows you to execute a section of code after a specified amount of time
has passed.
<script type="text/javascript">

Allow EZ_Result to display +5Pages link
You can download ez_resuls.php from http://php.justinvincent.com/
Allow EZ_Result to display nav bar like this
365 Results: [start] 1 2 3 4 5 +5Pages [last]
For this to work, I added a few lines to the ez_results.php class as follows
/********************************************************
* NAVIGATION FORMATTING
*/
var $show_next_x_page = true;
var $text_hover_msg_next_x = '+NUMBER Pages';
var $text_next_x_page = '+NUMBER Pages';
In function build_navigation(), I added the following.
$current_page = ($_REQUEST['BRSR'] / $this->num_results_per_page) +1;
$page_left = $this->num_pages-$current_page ;
if($this->show_next_x_page)
if ( ($this->num_pages >= $this->num_browse_links) && (($_REQUEST['BRSR']
+ $this->num_results_per_page) < $this->num_results))
{
if(($page_left * $this->num_results_per_page >= $this->num_results
) || ($current_page * $this->num_results_per_page) < $this->num_results
)
{
if($page_left >= $this->next_x_pages){
$cur_a = $_REQUEST['BRSR'] + $this->num_results_per_page * $this->next_x_pages;
$out .= $this->create_link(preg_replace("/\?.*/",'',$_SERVER['PHP_SELF'])
. '?BRSR='. ($cur_a) .$this->qs,$this->merge_num('next_x_page',$this->next_x_pages),$this->merge_num('hover_msg_next_x',$this->next_x_pages),$this->get_style('next')).'
';
}
else{
$cur_a = $_REQUEST['BRSR'] + $this->num_results_per_page * $page_left;
$out .= $this->create_link(preg_replace("/\?.*/",'',$_SERVER['PHP_SELF'])
. '?BRSR='. ($cur_a) .$this->qs,$this->merge_num('next_x_page',$page_left),$this->merge_num('hover_msg_next_x',$page_left),$this->get_style('next')).'
';
}

WML 怎麼顯示中文?
因為 WML 只接受 UNICODE, 如果你沒有經過 convert, 你就會看到亂碼
下面 mb_convert_encoding($str, "UTF-8", "BIG-5"); 就可以把字串 convert
成 Unicode 啦
<?php
// send wml headers
header("Content-type: text/vnd.wap.wml");
echo "<?xml version=\"1.0\"?>";
echo "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\""
. " \"http://www.wapforum.org/DTD/wml_1.1.xml\">";
?>
<wml>
<card>
<p>
<?php
$str = "哈囉";
$str = mb_convert_encoding($str, "UTF-8", "BIG-5");
print "<br/>Hello World! $str";
?>
</p>
</card>

How do I schedule the server to generate static HTML files from other dynamic web pages?
Some people would use Perl or PHP to grab data from the database and generate the HTML when the scripts are executed. I'm just too lazy to write another script for a dynamic web page which is already written in languages such as PHP, Perl, ASP, JSP, ColdFusion, etc.
What I do is create a shell script file and utilize OS' pipe function and a text browser to create the HTML file.
For example: create a text file called generate.sh
lynx -source http://someURL.com/yourCode.asp > yourStaticASP.html
lynx -source http://someURL.com/yourCode.php?Var=123 > yourStaticPHP.html
and do a chmod on the file, make sure it is executable, e.g., chmod u+x generate.sh
You may then schedule this script file in your cron table ;-)
How do I use a hyperlink to POST form variable?
How do I use a hyperlink to POST form variable?
<form name="aform" action="somewhere.php" method="post">
<input type="hidden" name="firstName" value=" <?php echo $firstName ; ?> ">
<input type="hidden" name="lastName" value=" <?php echo $lastName ; ?> ">
<input type="hidden" name="section" value="0">
</form>
Simply add a little JavaScript somewhere in the <head> ... </head> part of your page and we're done. The JavaScript would look something like this...
function clickpost(param)
{
document.forms.aform.elements .section.value = param;
document.forms.aform.submit;
return true;
}

How Do I get row number with SQL commands in MySQL?
Let's suppose we have a table look like this
Name PhoneNumber
-------------- --------------------
Peter 415-895-5689
John 408-854-4587
Louis 408-975-5986
And now I want to issue a SQL command which gives back a row number for each record which would look like this
RowNumber Name PhoneNumber
----------------- -------------------- ---------------------
1 Peter 415-895-5689
2 John 408-854-4587
3 Louis 408-975-5986
Under Oracle, this would be simple task, just issue the following SQL command
SELECT rownum, Name, PhoneNumber from table;However, MySQL does not offer such convinience as rownum. In MySQL, we need to do the following instead.
mysql> SET @rownum := 0;
mysql> SELECT @rownum := @rownum + 1 AS RowNumber, Name, PhoneNumber from table;Hope this tip can help you solve your current problem :)
