So there you go. There are currently 3 IPs available. I hope RPK has more to reveal (backup) if all three failed again (banned).

Copying and Deleting

sunsuron — Sat, 23 Aug 2008 18:49:43 +0000

Windows

xcopy   /E /I /C /Y /F
rmdir  /S /Q

Linux

cp -Rv <source> <destination>
rm -fr <dir>

Now I can perform


if(stristr( PHP_OS, 'WIN' ))
{
  $arg = 'xcopy '. $source .' '. $destination .' /E /I /C /Y /F 1>'. $outfile .' 2>'. $errfile;
  exec ( $arg, $out, $ret );
}
 
if(stristr( PHP_OS, 'Linux' ))
{
  $arg = 'cp -Rv '. $source .' '. $destination .' 1> '. $outfile .' 2> '. $errfile;
  exec ( $arg, $out, $ret );
}
?>

Avoid IE6, It’s time to upgrade

sunsuron — Sat, 23 Aug 2008 09:36:16 +0000

Stumbled into this javascript code while looking at jQuery Lightbox Plugin (balupton edition) code which redirect me to http://www.savethedevelopers.org/ and yes, it’s time to move on. Support this campaign by attaching the snippets at the top of you page. Thanks.

// Avoid IE6, It's time to upgrade
if ( navigator.userAgent.indexOf('MSIE 6') >= 0 )
{ // Is IE6
  // Include Upgrade Message
  var headEl = document.getElementsByTagName('head')[0];
  var scriptEl = document.createElement('script');
  scriptEl.type = 'text/javascript';
  scriptEl.src = 'http://www.savethedevelopers.org/say.no.to.ie.6.js';
  headEl.appendChild(scriptEl);
  // Kill Lightbox
  return null;

Method to determine whether a year is a leap year

sunsuron — Thu, 14 Aug 2008 14:45:59 +0000

How to determine whether a year is a leap year

If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.
If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.
If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.
The year is a leap year (it has 366 days).
The year is not a leap year (it has 365 days).


function is_leap_year1( $year )
{
	if ((($year % 4 == 0) AND ($year % 100 != 0)) OR ($year % 400 == 0))
		return true; // is leap year
	else
		return false; // not a leap year
}
 
function is_leap_year2($year)
{
	if( $year % 400 == 0)
	{
		return true; // is leap year
	}
 
	else if ($year % 100 == 0)
	{
		return false; // not a leap year
	}
 
	else if($year % 4 == 0)
	{
		return true; // is leap year
	}
 
	else
	{
		return false; // not leap year
	}
}
 
$year = @$_GET['year'] ? $_GET['year'] : 2008;
print '';
var_dump( $year ) ."\n";
var_dump( is_leap_year1($year)) ."\n";
var_dump( is_leap_year2($year)) ."\n";
?>

The folder size of /usr keep increasing

sunsuron — Wed, 06 Aug 2008 10:17:27 +0000

As the topic stated, the folder /usr keep increasing and I don’t have enough skill to identify what is it or where exactly the problem source. It could be a log file but even du -ch

I still unable to find it. Any idea?

So far this is the only suggestion that make sense:

[root@webhosting /root]# cd /
[root@webhosting /]# du -k --max-depth=1 /usr | sort -nr
4545976 /usr
1591248 /usr/src
1326160 /usr/share
707120  /usr/lib
452592  /usr/local
156864  /usr/bin
100048  /usr/include
96468   /usr/libexec
81116   /usr/X11R6
32820   /usr/sbin
1412    /usr/kerberos
76      /usr/man
16      /usr/lost+found

DocumentRoot must be a directory error

sunsuron — Thu, 31 Jul 2008 14:30:04 +0000

The error:

[root@hostname ~]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd: Syntax error on line 280 of /etc/httpd/conf/httpd.conf:
DocumentRoot must be a directory
                                                           [FAILED]
[root@hostname ~]#

I simply cannot restart httpd even the syntax is correct and the directory exist with the correct permissions. Disabling SELinux is the only temporary solution so far which is highly NOT recommended. :((

[root@hostname ~]# system-config-securitylevel

[root@hostname ~]# service httpd start

The Software Business 101

Creating something cool is easy but maintaining can be disastrous. The code works but real challenges are when several different system involved. There are 2 things that client will always request by default.

Get the cheapest deal
Complete it ASAP

This is what usually happens:
