Compiling Linux Kernel

    I'm writing a short how-to to compile linux kernel. This process is for 2.6 series of kernel. Building kernel requires no programing knowledge. All it require is knowledge of hardware u have. Compiling kernel for ur system improves performance of ur system as much as 40% depending on ur system configuration.
    First download latest linux kernel from kernel.org. At the time of writing 2.6.18 kernel is released. Downlaod linux-2.6.18.tar.gz file. Extract this using tar zxvf linux-2.6.18.tar.gz. This will extract all files in foler linux-2.6.18. cd to this foler.
    Now u have to configure kernel for your system. To configure kernel run
make menuconfig
or
make xconfig
    This command will open an window. In this select/deselect option for ur system. Deselect all other driver for devices that you don't have and select only those devices that u have.
For example if u have intel motherboard, then in audio driver enable only intel driver and disale all other sound card drivers.
After completing configuration save and exit.
Now run
make bzImage
This will build kernel for ur system.
Then
make modules
This will build kernel modules for ur system. Now install modules using
make modules_install
And finally install kernel bu running command
make install
This will also update ur bootloader (if grub) entries. Now reboot into newly build kernel.

When I changed boot order to make trace default kernel, grub is installed on root partition than MBR, so my system become unbootable. I got only 2 days of holidays. I come to know abt this problem after I returned to my work city (Indore) from Home (Khandwa). So I could not fix the problem. So I have to fix it via phone. My brother booted the system with Opensuse 11.1 dvd. My brother is not very technical person but he is advace-level PC user. We have never used recover/rescue installed system option. We selected automated recovery mode. It first checks all partitions and packages, all of them found is good state, setup found error boot loader configuration, we loaded boot loader configuration from disk and found that grub is installed on root partition instead of M...

Adding additional class to a button in drupal

Recently we were building a multi-domain site, we are using same theme for all sites but we want to have different colors for buttons for each domain. We achieved this using my overriding theme_button in template.php of theme, here is the snippet. /** * Overwrite theme_button() * @file template.php */ function mytheme_button($variables) { $element = $variables['element']; // Add some extra conditions to make sure we're only adding // the classto the right submit button Now add our custom class if (isset($element['#attributes'])) { $element['#attributes']['class'] [] = 'button'; $domain = domain_get_domain(); $element['#attributes']['class'] [] = $domain['machine_name']; } $variables['element'] = $element; return theme_button($variables); }

Dana Abdulrazak - most heroic runner

Only female athlete from Iraq. She is a real hero, who come from war torn country. Olympic "superlatives" to be remembered_English_Xinhua Dana Abdulrazak - most heroic runner Photo taken on Aug. 21, 2008 shows Iraqi athlete Dana Hussein Abdulrazak hold a Chinese knot in Beijing, China. Iraqi women runner Dana Abdul-Razzaq has received as loud applause as champions. The Iraqi team's only woman faced many obstacles to reach Beijing, from a sniper's bullets to a lack of training facilities and religious and cultural opposition to female athletes. Before the Olympics, she was told that Iraq was shut out of the international sports gala. When her coach consoled her by saying that she could take part in the 2012 Olympics, she broke into tears, "who knows if I could live that long!"
