You've a lot unused kernels. Remove all but the last kernels with:
sudo apt-get purge linux-image-{3.0.0-12,2.6.3{1-21,2-25,8-{1[012],8}}}

This is shorthand for:
sudo apt-get purge linux-image-3.0.0-12 linux-image-2.6.31-21 linux-image-2.6.32-25 linux-image-2.6.38-10 linux-image-2.6.38-11 linux-image-2.6.38-12 linux-image-2.6.38-8

Removing the linux-image-x.x.x-x package will also remove linux-image-x.x.x-x-generic.
The headers are installed into /usr/src and are used when building out-tree kernel modules (like the proprietary nvidia driver and virtualbox). Most users should remove these header packages if the matching kernel package (linux-image-*) is not installed.

To list all installed kernels, run:

deepaknverma

#!/usr/bin/env sh
 
# checks to see if running 
launchctl list | grep mongo
 
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
launchctl remove homebrew.mxcl.mongodb
 
pkill -f mongod

Node.js is a Javascript platform for server-side programming that allows users to build network applications quickly. 

Building nodejs server in ubuntu is fairly simple and easy. With few commands you can make a nodejs server up and running in not time.
Nodejs generally runs of port 3000 but that is not mandatory, you can use any other port you want to make your server more customised.

There are few path, you can follow to get your Nodejs up and running on Ubuntu 14.04

Ubuntu newb running 11.04. Seems like a lot of other people are having trouble mounting the network drive at boot in fstab. Tried a bunch of things and cruising the forums but just ended up being a mess. Finally got it going and I though I would share for others and if I need to do it again later.

Also worth noting is that it is not very secure as the file you save the credentials in is in plain text, but I didn't care at this point.

1. Install smbfs:
   sudo apt-get install smbfs

2. Then create a folder inside of the /media directory to mount the share in:
   sudo mkdir /media/server

Please take a look at the original article (http://www.softwareprojects.com/resources/programming/t-optimizing-nginx-and-php-fpm-for-high-traffic-sites-2081.html) as it includes excellent configuration file examples.

1. Switch from TCP to UNIX domain sockets:
When communicating to processes on the same machine UNIX sockets have better performance the TCP because there's less copying and fewer context switches.

2. Adjust Worker Processes:
Set the worker_processes in your nginx.conf file to the number of cores your machine has and  increase the number of worker_connections.

3. Setup upstream load balancing:
Multiple upstream backends on the same machine produce higher throughout than a single one.
