Postman – A simple image uploading application for Ubuntu/Linux Mint

Postman is a nice little application that can upload your images to various services, currently it supports Google Plus, Picasa, Flickr, Ubuntu One.

It’s an easy to use application, with an awesome looking graphical interface and minimal set of features, but it does support drag and drop feature for image upload. You can also set basic attributes for the images such as title and description.

setup VPN (Virtual Private Network) connection in Ubuntu 12.04/12.10

VPN (Virtual Private Network) connections are great for those who want higher degree of security on the Internet. All of your web traffic will be encrypted. So even if you’re browsing a non-ssl website – your information (e.g login details) is always safe with VPN.

So even if you’re just a web surfer or a heavy torrent downloader you can try VPN to save yourself from the common spy (your ISPs and goverment) and it will also allow you to bypass geographical restrictions (it means if you use a US based VPN then you can browse CBS or Hulu videos from anywhere in the world).

Which VPN provider to choose ?

There are lot of VPN providers, I recommend Private Internet Access (I’m using it – and it’s working great) – it’s good and costs only few bucks a month. If you’re using other VPN provider then you may have to adjust few things according to their recommendation.

Setting up VPN on Ubuntu / Linux Mint

step 1. Go to Network settings and create a new interface for your network – select VPN.


Then a new dialog will appear to select the interface type – select VPN .

New Interface - VPN

step 2. Then select the VPN type – choose PPTP (Point to Point Tunneling Protocol).


step 3. Now – add your VPN account details (gateway, there are various gateway you can choose from here is the list of gateways).

vpn-provider - details

step 4. After adding some basic details for your VPN provider, go to advanced settings and enable MPPE.



step 5. Now – enable VPN and enjoy the higher degree of security :)

That’s all, your VPN setup is done and you can switch between vpn or direct access – just in single click.

Note: using vpn may slow down your browsing experience, it’s not recommended when your connection speed is too slow.


How to Install Nginx web server on Ubuntu 12.04/12.10

Nginx is a lightweight web server (HTTP, SMTP, IMAP, POP3 ..). It has very low memory footprints with higher degree of concurrency. It’s a free and open source software, runs on all major OS (Unix, Linux, BSD, Mac OS X, Microsoft Windows and more).


Setup Nginx on Ubuntu (12.04) LTS Server

Nginx is already available in Ubuntu repository, but it’s very outdated (it may be ok for development or testing but not for deployment) so for production environment you should install the newer version – either from the source or PPA.

1. Update

sudo apt-get -y update
sudo apt-get -y upgrade

2. Dependencies

For adding ppa you need to install the python-software-properties package.

sudo apt-get -y install python-software-properties

3. Install nginx

sudo apt-add-repository -y ppa:nginx/stable
sudo apt-get -y update
sudo apt-get -y install nginx

4. Start the server!

sudo service nginx start

Now, move on to the address (IP address of your VPS or the domain name or the localhost(in case of development environment)). You should see the default page served by nginx.

5. setup server configs

For editing file over the ssh, you can use a command line editor such as Vi or Nano. I recommend nano if you want a text editor without any learning curve.

Install Nano, a lightweight text editor

sudo apt-get -y install nano

Then create a server configuration file for your app/site. (you could also just edit the global config(/etc/nginx/nginx.conf), it’s fine if you’ve only one app/site running on a virtual private server but if you plan to deploy multiple apps/websites to a single VPS – then you should create seperate configs for each website)

sudo nano /etc/nginx/sites-available/

After creating the config file (if you don’t know how – then read the official tutorials), create a symlink

sudo ln -nfs /etc/nginx/sites-available/  /etc/nginx/sites-enabled/

Now, restart the server!

sudo service nginx restart
Google Chrome : Ubuntu 12.10

Google Chrome for Ubuntu 12.10 “Quantal Quetzal”

Ubuntu 12.10 comes with Mozilla Firefox by default, it’s a great browser! but if you want a secondary web browser (or you like Google Chrome) then can also try Chromium (the open source project upon which Google chrome is based on) – it’s available there in Ubuntu Software Center, but you won’t get some chrome specific features such as in built flash player etc. (but you can install that separately if you want, by installing ubuntu-restricted-extras package, refer few things to do after installing ubuntu 12.10)

Google Chrome : Ubuntu 12.10

Installing Gdebi Package Installer (Optional)

sudo apt-get install gdebi

Installing Google Chrome

  • Download Google Chrome
  • Open the downloaded file with Gdebi Package Installer or ubuntu software center (but it may cause some dependency errors, in that case you will have to manually install the missing dependencies or execute sudo apt-get install -f), in case if you haven’t already installed the Gdebi package installer (which is a lightweight program for managing *.deb packages)

How to Install KDE Desktop Environment in Ubuntu 12.10

Ubuntu 12.10 comes with Unity Desktop environment/shell (based on GNOME 3). A lot of users love unity, they like the cools features of unity (Unity dash, lens, launcher etc) , but there are lots of haters too. Fortunately, there are many options available – Gnome shell, KDE, XFCE, MATE, Cinnamon, etc.

KDE – Desktop Environment

KDE is one of the most popular and a classic desktop environment. It’s easy to use and it has lot of cools apps (somewhat like Gnome), specially for newbies (moving from Windows XP/7/8).


In Ubuntu 12.10, it’s there in package repository, by default. KDE plasma desktop and apps are bundled together in various ways. Choose something that suits you well, or just go with second one (kde-plasma-desktop, with minimal set of applications).

KDE standard

it contains KDE plasma desktop and standard set of applications such as Kate (default editor, like gedit), Konqueror (default web browser), Kget (Download Manager), KMail (email client), Dolphin (File Manager), Konsole (terminal) etc. To install standard package of kde, open a terminal and execute the command –

sudo apt-get install kde-standard

KDE Desktop Minimal

If you just want to give it a try or may be you don’t want the applications to be installed by default (you can always install later), then prefer this minimal package – that installs KDE plasma desktop with minimal set of apps.

sudo apt-get install kde-plasma-desktop

KDE Netbook Minimal

As the name suggest, it’s more suitable for netbook users.

sudo apt-get install kde-plasma-netbook

KDE Full

If you want the complete package of apps, along with the core desktop environment (KDE Plasma), then it’s the best option for you (but it may take more time to install depending on your internet speed).

sudo apt-get install kde-full

That’s All, enjoy the cool charming look of KDE.
