System Requirements for ubuntu 11.04

system requirements for Ubuntu 11.04

Ubuntu 11.04 (or Natty Narwhal) or most of the Linux distribution has usually a lower hardware/system requirements as compare to Windows or Mac OS X, and of course Linux based operating systems are more compatible with older hardwares, so in general you don’t need to worry about these minimum hardware specifications and requirements, unless you are using a very old computer. Anyhow, before going to install Ubuntu 11.04 from USB or CD/DVD , you are recommended to check this minimum system requirements.

For Ubuntu 11.04 system requirements may vary depending on the need i.e the purpose for which you are using Ubuntu 11.04. Suppose, if you want to play games (heavy games which requires 3D acceleration..) then of course you would need much RAM as well as a dedicated graphics card such as Nvidia, ATI etc (i.e a separate GPU (Graphics Processing Unit) ), this will be true for similar other jobs which need high graphics capability. If so then get a best graphics card for Ubuntu Desktop.

Ubuntu 11.04/10.10/10.04 System requirements

The system requirements for Ubuntu 11.04 is same as compared to it’s predecessor 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx),  although Unity may not be supported (or it will run with very poor performance, if that’s the case then switch to Gnome and turn off all those fancy desktop effects) in 3D mode on older computer with low graphics capability, in that case it will fall back to Unity in 2D Mode (or to Gnome in older versions of Ubuntu).

Minimum Hardware Requirements

  • 1 GHz Pentium or better processor (such as Dual Core, Core 2 Duo, i3, i5,i7… )
  • 384 MB of primary memory (RAM) although, at-least 512 MB is recommended
  • 5 GB of harddrive space but it would be better if you have more than 10GB (unless you are installing Ubuntu 11.04 , for testing or any specific purpose)
  • Either a CD/DVD drive or a USB (Universal Serial Bus) port (or both)
  • a Graphics Card if you want to use the Unity in 3D Mode, which is the default mode of Ubuntu 11.04, although it’s optional because you can still use Gnome 2.* efficiently by turning off the compiz or desktop effects which consumes a lot of resources
  • A monitor (CRT, LCD-TFT, LCD-LED or whatever) capable of displaying output at Resolution (Min) : 800×600
  • Internet Connection is not necessary but it’s recommended

That’s All.

how to setup OpenDNS on ubuntu 11.04/10.10/10.04

What is OpenDNS ?
OpenDNS is a DNS (Domain Name Resolution, it’s basically a naming system which maps human friendly domain name (e.g sudobits.com) to I.P (Internet Protocol) address e.g 173.193.206.153 ). Each time ( if it’s not cached ) when you visit a website, your browser sends a DNS lookup query to the DNS server, most probably to your ISP DNS but you can configure your computer to use some other DNS servers such as OpenDNS for name resolution purposes, if you want. So in the end of this post you will learn how to use OpenDNS on your Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) or any other Linux based operating systems such as Linux Mint, Fedora, Debian etc (Procedure is almost same).

A typical ISP (Internet Service Provider) DNS server works well in general but there are few extra advantages with OpenDNS, some of the important features are –

  • Open DNS is very fast (may not be true for non US users e.g if an Indian users will use OpenDNS instead of the BSNL DNS server, then it will be slow because BSNL DNS servers usually takes 400ms to resolve an I.P address while OpenDNS would take more than 1000ms due to high latency)
  • It protects you from the phishing attacks
  • Content filtering features are also available which can be used to block unwanted sites
  • it’s free for personal use

Setup OpenDNS on Ubuntu 11.04/10.10/10.04 in few simple steps

#1 : Right Click on Network icon -> Edit Connections.

network-applet-ubuntu

#2 : Then click on Add button to add a network or exist the existing one (Auto eth0) but it’s better to give configure a new one so that you can use both DNS depending on the need.

Network connections : open DNS

#3 : Next, click on IPv4 settings and select “Automatic (DHCP) Address only” (DHCP ( Dynamic Host Configuration Protocol) servers are used to allocate I.P address(usually Dynamic I.P Address) to the users) in Method. You can check the box if you want to connect automatically when your computer starts, better leave it uncheck. Give it a human friendly name e.g ‘OpenDNS’.

setup-open-dns-in-ubuntu

In ‘DNS servers’ field put these I.P Addresses :

208.67.222.222,208.67.220.220

Finally click on Apply button to complete the OpenDNS configuration process.

#4 : Now, left click on the network icon (Top Right of the panel) and select the network (as created in above steps) by clicking on the name of the connection and wait for few seconds. That’s all.. now you are ready to enjoy the surfing with OpenDNS.

Set up ruby-on-rails

install Ruby on Rails in ubuntu 10.10/11.04

ruby-on-rails

‘Ruby on Rails’  (ROR) is one of the most popular and productive open source framework that allows you to develop web applications very quickly with a lot of fun.

Ruby is a scripting language (like PHP) that focuses on ease of development and beautiful code. Ruby on Rails or simply ‘Rails’ is a web Apps development framework for Ruby programming language.

Rails is a cross-platform – web Apps development framework and this post will guide you in installing ‘Ruby on Rails’ framework on Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) LTS..procedure is same for all versions. gedit text editor is enough for ruby programming – (usually better than heavy weight IDE’s), you can also customize gedit to look like TextMate (very popular (text editor) among ruby developers who uses Mac OS X).

Ruby version 1.8.7 is installed by default, in most of the Linux based operating system or distributions such as Ubuntu, so what you need to install is – ‘Rails’ , Gems (Gems are modular components or libraries very similar to Package in java), git (git is one of the best – free and open source version control system (developed by Linus Torwalds), it is not strictly necessary but recommended) and curl. Before you move on for installing ROR, Apache (Not necessary because ROR ships with WEBrick, the default HTTP server for rails apps) and MySQL or SQLite should be installed.

Installing Ruby on Rails in Ubuntu

#1 : Install git (not necessary but recommended), the version control system.

sudo apt-get install git

or install from source – Download git (Latest Version : 1.7.5.4). Then extract the archive and move to the extracted directory and type the following command(s) to install it –

make && sudo make install

#2 : Install Curl (Command Tool for transferring data with URL Syntax).

Download it (Latest version : 7.21.7) and install in the similar way as you installed git (in step 1, using source)

#3 : Install  Ruby Version Manager (RVM), a command line tool which allows you to run multiple versions of ruby – such as 1.8.7 as well as 1.9.2. Gem will be installed along with this, if not, then install rubygems before proceeding to next step.

bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)

Then type the command given below, to check whether it has been correctly installed, the output after executing the command will be – ‘rvm is a function’

type rvm | head -1

#4 : Install Ruby 1.9.2 (1.8.7 is installed by default)

rvm install 1.9.2
rvm use 1.9.2

#5 : Install Rails

gem install rails

#6 : Install SQLite3 (Not necessary if you want to use MySQL but ROR uses SQLite database by default, so you need to install ruby and sqlite related packages and ORM libraries).

gem install sqlite3

That’s All..now you are ready to rock with ‘Ruby on Rails’. Create new Application using simple command and start the server.

rails new apps_name
cd apps_name
rails server

Now open your browser and type the following address in the address bar –
http://localhost:3000
