Youtube has been blocked in my country, such a lame we are! I don't know how they have blocked , Some sites of google aren't working. I wanted to use the android sdk to install some of the packages and found out It can't connect. As I am on Ubuntu I tried using the System wide network proxy option but it didn't work. I tried the settings in /etc/environment without result.
At last inserting the proxy settings at /etc/java-6-openjdk/net.properties worked for me.
As I am using the socks proxy , I set the ip and port and it's working for me in both eclipse and android sdk manager.

wordpress ajax with different WordPress Address and Site Address
If in your WordPress General Settings WordPress address and Site address are different(if two domains are different), using Ajax in the frontend can be a little tricky. Usual approach is to localize a script :
wp_localize_script('some_script_name, 'SomeVar', array(
'ajaxurl' => admin_url('admin-ajax.php')
));
and you can get the ajaxurl from your javascript code by SomeVar.ajaxurl
admin_url('admin-ajax.php') will return an url in respect to the Wordpress address. So, when you make an ajaxcall , it won't work, javascript will throw a cross-domain exception.
The solution is to use the home_url() and appending the ajax url:
wp_localize_script('some_script_name, 'SomeVar', array(
'ajaxurl' => home_url('/').'/wp-admin/admin-ajax.php')
));
and don't forget to add the nopriv hook:
add_action('wp_ajax_nopriv_action_name', 'function name');
other wise the frontend ajax won't work, as the request relays back to the WordPress url even if you're logged in as admin the request will not carry that info.

Linux get Processor Info
Found some useful commands to get the cpu info.
sudo lshw -C cpu
cat /proc/cpuinfo
sudo dmidecode --type processor
Also do
ls /sys/devices/system/cpu/
To get an idea about processors, cores, multithreading check

Olympic 2012
I have been passionately following the Olympic 2012 especially the swimming events. I was amazed to see the 16 year old girl Ye Shiwen from China winning the gold Medal in 400m Medley. I became stunned while I found out the reaction of some of the people. They suspect her performance enhanced by dope! That's strange, when Stephanie Rice improved her personal timing 5 seconds that was a great performance or when the 15-year-old Katie Ledecky from USA wins the 800m making almost a world record , nobody questions her performance. After a lot of hard works and perseverence does the athlete really deserve this?

Python Basics
The single most important thing to know about python is that everything is object in python.
use dir() or the inspect module to inspect any object. The help() function is very useful. It's a wrapper around pydoc module.I use it frequently to know the statements like print, raise etc.
dir.__doc__ will give you the details.
inspect.getmembers() ouputs a list of all members of the passing object.
To know about any function at first try the __doc__ first

Openssh as proxy server connection
Today I discovered the ssh -D feature which can be used as a secure proxy server connection.
For example I am using ssh -D 4589 username@hostname to make a secure connection to the hostname. 4589 is the local port to be used . After connecting to the remote hostname If you configure the proxy settings in the browser( In the socks field put 127.0.0.1 and as port put 4589 or whatever port you define in the command ) you'll be using your own proxy server! no need to use the insecure public proxys.
Check the manual of SSH for more info
