Installing Ruby on Rails on Linux Machine

You can follow the steps below to install ruby on rails on your linux machine.Open your terminal and follow the steps below.

First we are going to install curl,we will be fetching RVM by using curl.
sudo apt-get install curl

Installing RVM:-
RVM means ruby version manager it is used to maintain multiple ruby versions.It is highly recommended to use RVM  as sometimes you may want to use earlier ruby versions(ex:- 1.8.7,1.9.3) for older projects and current version for the latest projects(ex:- 2.1) and this problem is solved by RVM,you can refer the documentation for other versions and full details .

We can install RVM using the following command.

curl -L get.rvm.io | bash -s stable
In order to source the rvm scripts file we will be using this command. 

source ~/.rvm/scripts/rvm
This command will install the dependencies.

rvm requirements
you can get the list of ruby versions available by using

rvm list known
Now we can install the required ruby version with this command

rvm install RUBY_VERSION
ex:- rvm install 2.1.0
now we can check the ruby version installed by using

ruby -v

If you want to set ruby 2.1.0 as default ruby version then use

rvm --default use 2.1.0

As both RVM and some version of ruby are installed in our machine and we can proceed with installation of rails.
we can install rails by using the following command.

gem install rails

The above command will install the latest rails version,if you want to install some other version of rails you can use

gem install rails -v SOME_VERSION

ex:- gem install rails -v 3.2.11
That's it you can check your rails version using rails -v in your terminal.

How To install Android environment:

Here’s a quick start installation guide to get you up and running with the Google Android Software Development Kit (SDK). This guide will describe how to install the Android SDK and set up your chosen development environments. If you’ haven’t already done so you can download the Android SDK from the link below, then we can get started.

First you’ll need to download the Android SDK source files:
( http://code.google.com/android/download.html )

System Requirements

In order to first use the Android SDK code and tools for development you will of course need a suitable environment develop from.

Currently the following operating systems are supported:

• Windows XP or Vista
• Mac OS X 10.4.8 or later (x86 only)
• Linux (tested on Linux Ubuntu Dapper Drake)

You will also need to install a suitable development environment such as:

1. Eclipse
2. JDK (Java Development Kit)
3. Android SDK
4. ADT (Android Development Tools)

1.Installing the Eclipse:

Ø  For Windows, you can go to http://java.sun.com/javase/downloads and choose JDK 6 Update.

Ø  In Mac OS X, we don't need to do this as JDK (5.) is built-in installed with Mac OS X.

3.Installing the Android SDK

First you will need to download the Android SDK pack .zip archive, once downloaded find a suitable installation location on your machine and extract the zipped files.

Mac OS X

1. In the home directory locate the .bash_profile and locating the PATH variable add the location to your $SDK_ROOT/tools folder.

6. double-click on Path (under System Variables)
7. Add the full path to the tools/ directory:

5. In the resulting Install Details dialog, the Android DDMS and Android Development Tools features are listed. Click Next to read and accept the license agreement and install any dependencies, then click Finish.

Speed up your ruby-on-rails Application using webp Images

Speed up your Ruby on Rails application using WebP images

What is WebP?

WebP is an image format that employs both lossy and lossless compression. It’s been developed by Google. So far only Google Chrome (+ Android) and Opera support this type of images, as we can show webp images in Chrome and Opera, and png, jpg or gif images in the other browsers.

WebP and Ruby on Rails

After the webp library has been released, I wrote a webp gem – webp-ffi. You can use it to work with webp images in Ruby. Also, two good Ruby gems were released a bit later – sprockets-webp and carrierwave-webp. Sprockets-webp provides a Rails Asset Pipeline hook for converting PNG and JPEG assets to the WebP format. To use it, just add this gem in the Gemfile.
