So given a number count the number of 1's it has set in it's binary representation. Easy!
Just keep on dividing by two (or bitshift right) and see if the number is odd or even and increment the count based
on this criteria like so:

getNumBitsSet(int val) {
 int count=0;
 while(val>0) {
  if(val % 2 != 0)
    count++;
   count = count / 2;

I already had git ssh keys set up and now wanted to use the same one for logging into my Digital Ocean droplet. To copy over ssh keys to the remote droplet just do:

ssh-copy-id user@address

To get rid of them run:

gconftool-2 -s -t string '/apps/compiz-1/plugins/decor/screen0/options/decoration_match' '!(state=maxvert & state=maxhorz)'

So there are times when you need to connect to a remote server and do some sort of work on the files.
One alternative is to use an FTP client such as FileZilla and constantly upload to view changes.
Scratch that, just use SSHFS! It mounts the remote drive/directory on your local machine and you can
work/save files and the changes will be automatically uploaded.

First install sshfs, on Ubuntu: sudo apt-get install sshfs

In order to mount a drive use your usual ssh account and specify a directory on which you would like the mount
to occur like so:

First we need to install MySQL with the following:

sudo apt-get install mysql-server

Note: You will be prompted for the root password in the middle of the installation.

Now this is optional (for uses with MySQL workbench):
sudo apt-get install mysql-client

Now to test it out try: mysql -uroot -p

The only simple command you need is:

sudo apt-get install apache2

Navigate to: http://localhost and you shall see the magical 'It works!' file! 

Now to get PHP working:

sudo apt-get install php5
sudo apt-get install libapache2-mod-php5

ps

Fire up the terminal and run this command:
dpkg -l | awk '/linux-[^ ]+-[0-9]/ {print $2}'

It should print all of the available kernel versions.

Check which version of kernel you are currently running by typing in: uname -a

Once you know which new version of the kernel you want to remove type:

sudo apt-get purge linux-headers-3.8......

Recently my dorm wireless network has been working fine on all devices except my Ubuntu 12.10 laptop.
So I did some research and some simple fixes that have seemed to work for now are:

-change router security to WPA2 only
-change router channel from automatic to either 1 or 11
-if router is b/g/n, attempt to change to b/g (was not able to do this with my router)
-sudo vim /etc/modprobe.d/rtl8192ce.conf and insert the following line: 
'options rtl8192ce ips=0 fwlps=0 swenc=1 debug=2'

Switched to Ubuntu 12.04 and entered the following to see if wireless works better:
