Colouring MOTD

Terminal should be ANSI compliant and support colour escape sequences. Modern terminal should do the job.

The following is a list of escape sequences

The ^[ is produced by pressing Ctrl-V then ESC

I’m using vi as text editor and there’s no problem with ctrl-V ESC, i’m not test it on other text editor.

^[[0m    - Reset the terminal characteristics
^[[1m    - emphasis (bold)

^[[30m    - Foreground black
^[[31m    - Foreground red
^[[32m    - Foreground green
^[[33m    - Foreground yellow
^[[34m    - Foreground blue
^[[35m    - Foreground magenta
^[[36m    - Foreground cyan
^[[37m    - Foreground white

Speeding up your website using eaccelerator and memcache/memcached

Php default behaviour is always re-compile our script everytime accessed by users/browsers. eaccelerator can increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

Here’s how to install eaccelerator extension

$ wget http://bart.eaccelerator.net/source/0.9.6/eaccelerator-0.9.6-rc1.tar.bz2
$ tar xjf eaccelerator-0.9.6-rc1.tar.bz2
$ cd eaccelerator-0.9.6-rc1
$ phpize
$ ./configure
$ make
$ sudo make install
$ cd /var/cache
$ sudo mkdir eaccelerator
$ sudo chown -R apache:apache eaccelerator

Toggle IP From Static to DHCP to Static Tool

I’ve created small tool(for windows XP/Vista), writen in visual basic 6.this tool was created for switching between static LAN ip to DHCP and back to original static IP (original IP saved in temporary variable) without opening network configuration, And without typing anything, just few mouse click is what we need. This tool using Windows Management Instrumentation for enumerating all network interface, get parameters, and set parameters.

Set objwmiservice = GetObject("winmgmts:\\.\root\cimv2")
Set colNIC_Config = objwmiservice.ExecQuery("Select * from Win32_NetworkAdapterConfiguration WHERE Index='" && _
                    Netconf.strIFIndex(CboIF.ListIndex) && "' AND IPEnabled=TRUE")
