Installing XBMC for Raspbian

I bought Raspberry a month ago and I had so many research plans for this device. One of my idea is to make my old TV become complete media center solution. After googling some references I found that XBMC could help me!

Installing XBMC for Raspbian is really straight forward.

1. First add repository for the XBMC binaries, type this on your console :

sudo echo "deb http://www.deb-multimedia.org wheezy main non-free" >> /etc/apt/sources.list

2. Get the GPG key for this repository

wget http://www.deb-multimedia.org/pool/main/d/deb-multimedia-keyring/deb-multimedia-keyring_2012.05.05_all.deb

3. Install the GPG key you just download

sudo dpkg -i deb-multimedia-keyring_2012.05.05_all.deb

4. Update your package list

sudo apt-get udpate

5. Install XBMC

sudo apt-get install xbmc

Follow the instructions on your console.

6. Start XBMC
Type “xbmc” on your console to start XBMC

xbmc

Here’s the screen of XBMC

I tried some features such as Podcast, Internet Radio, Youtube, Vimeo, and Web browser. Everything works normally, but the web browser need more improvement! Also I test XBMC remote control using android device, this remote control is really helpful! Another thing what I love is we can install add-ons for XBMC from the XBMC dashboard.

Remove index.php on CodeIgniter using .htacces

By default CodeIgniter framework url will includes index.php, it’s pretty easy to remove index.php from your url to work with CodeIgniter using .htaccess.

I assume that your web server already enable mod_rewrite module (mostly any web hosting already enable it). Create new file .htaccess in your CodeIgniter code root (same level with index.php) as like this.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Save it, and violaa… your CodeIgniter has pretty URL.

How to disable wordpress toolbar for all users

New wordpress engine has a feature called toolbar and its shown in the top of our blog page. What ridiculous is there’s no built-in function to disable this toolbar for being shown to all our users, which mean the users have to manually disable it in their profile page. Fortunately we can use this snippet to disable this toolbar.

Add this snippet to your theme functions.php file

function my_function_admin_bar(){
    return false;
}
add_filter( 'show_admin_bar' , 'my_function_admin_bar');
