BING comes up with a beautiful background everyday. I thought why not set this background as my desktop wallpaper. But it would be a cumbersome task to set it manually. So I searched (Googled, BINGed) for some script which will do this for me. I found BING Downloader which does this task on Windows. I could not find any such script for GNOME. So, I thought of writing one.

I wrote a script which when executed automatically sets the GNOME wallpaper as BING background of the day. This is a PHP script. To execute this script you need to have php installed on your system. You can install php in Ubuntu as

sudo apt-get install php5 php5-cli

Now you are all set to download this script. Download Link: http://www.spsneo.com/scripts/bing_wallpaper.tar.gz

Download this file, extract the script file. Now you can run the script from terminal :
php bing_wallpaper.php

And your wallpaper is set. You can run this script daily from your terminal or you can set a cron job for the same or you can set up an icon in your gnome panel for this script.

I will keep updating this script. And I am also planning to write the same script in python. So check back again if you dont want to install php on your system.

Send your feedbacks and suggestions.

Update 1: I have modified the script to work with http proxy. Just assure that the environment variable http_proxy is properly set.

Update 2: Modified the script to keep the image centered on the desktop with black background. Try it out.

I normally use terminals to navigate through directories in my computer. I often have to remember the executable filename of different applications to open files. Like to open a pdf file I have to remember evince, for an audio or video file – vlc. But its really difficult to remember executable filenames for all types of files. For example I don’t remember how to open a .xls file from command line.

There’s a command which open files using GNOME file handlers – “gnome-open”. Now, when I have to open any file I just type in “gnome-open <filename>”. Simple !

To make things more simple I have made an alias ‘go’ for ‘gnome-open’. Now opening a file from terminal is as easy as typing “go <filename>” in terminal.

There are large number of archive file formats – .zip, .tar.gz, .tar, .gz, .7zip, .rar, etc etc..

I find it difficult to remember the command line options for extracting different archive file formats. So, I wrote a bash function which given a archive filename as an input extracts it.

Here’s the function :

extract () {
if [ -f $1 ] ; then
case $1 in
*.tar.bz2) tar xjf $1 ;;
*.tar.gz) tar xzf $1 ;;
*.bz2) bunzip2 $1 ;;
*.rar) rar x $1 ;;
*.gz) gunzip $1 ;;
*.tar) tar xf $1 ;;
*.tbz2) tar xjf $1 ;;
*.tgz) tar xzf $1 ;;
*.zip) unzip $1 ;;
*.z) uncompress $1 ;;
*) echo "'$1' cannot be extracted via extract ()" ;;
esac
else
echo "'$1' is not a valid file"
fi
}

This function is pretty self explanatory. But as it is not powerful. It becomes the ultimate tool for extractive archive files if you copy this function in you bashrc file (~/.bashrc).

Now you can simply extract any file like this:


$extract test.tar.gz

Hope you like this function.

Note: This function doesn’t work with files have space in its name. I didn’t waste time in solving this issue as I normally don’t use such filenames. If any of you solve this issue, please do let me know. I would include it with your name in this post.

Today, I suddenly saw a new feature of Google search. One can now promote a search result, comment on a search result or remove a search result. Take a look below :

I am sure this feature will help Google provide better and more personalized results !

Happy Googling !

Yeah I am using Windows vista for the first time today. I am loving some cool tools. I am posting from Windows Live writer !

Windows is also not that bad !
