Install and Use Redis Server

Sort Introduction

Redis is an extremely fast, atomic key-value store. It allows the storage of strings, sets, sorted sets, lists and hashes. Redis keeps all the data in RAM, much like Memcached but unlike Memcached, Redis periodically writes to disk, giving it persistence. It is quite useful as both a cache store and as a full-fledged, NoSQL data store.

This blog describes getting Redis working on your rails application.

Initial setup

  1. Start off by updating all of the apt-get packages:
    $ sudo apt-get update
  2. Now Download a compiler with build essential which will help us install Redis from source:
    $ sudo apt-get install build-essential
  3. Now in the last we need to download tcl:
    $ sudo apt-get install tcl8.5

Redis Installation

Thats all… Finish Now try to run the redis server into your machine

$ redis-serverredis

Stop redis server running in background :

  • $ killall redis-server


  • sidekiqctl

Deploy Ruby on Rails project with Passenger and Nginx

I’m assuming that you have installed ruby and rails at your server and have a Ruby on rails project to deploy with Passenger and Nginx

Step 1 –  First of all, we need to add a Sudo User to our system so user can have privilege to access the files.

create a user if not exists, in this example, I will explain to create a root user

tecorb@tecorb-Lenovo-B40-80:~$  adduser root

(this will ask few questions like your password etc.)

Step 2 – Now we have to add this new user to the sudo group


tecorb@tecorb-Lenovo-B40-80:~$ gpasswd -a root sudo

Step 3 – Now we need to install Passenger and Nginx

First of all we will install a PGP (Pretty Good Privacy) key:

tecorb@tecorb-Lenovo-B40-80:~$  sudo apt-key adv –keyserver –recv-keys 561F9B9CAC40B2F7

Now we have to create an APT (Advanced Packaging Tool) source file

tecorb@tecorb-Lenovo-B40-80:~$  sudo vim /etc/apt/sources.list.d/passenger.list

And insert the following line in the file:

deb trusty main

Press ESC then :wq and hit enter, Now our file has been saved through vi editor

Now we need to change the owner and permissions for this passenger.list file:

tecorb@tecorb-Lenovo-B40-80:~$  sudo chown root: /etc/apt/sources.list.d/passenger.list

tecorb@tecorb-Lenovo-B40-80:~$  sudo chmod 600 /etc/apt/sources.list.d/passenger.list

Now we have to update our APT cache:

tecorb@tecorb-Lenovo-B40-80:~$   sudo apt-get update

And finally, we will install Passenger with Nginx:

tecorb@tecorb-Lenovo-B40-80:~$  sudo apt-get install nginx-extras passenger

Step 4- In this step we will open the Nginx configuration file for some changes:

tecorb@tecorb-Lenovo-B40-80:~$  sudo vim /etc/nginx/nginx.conf

now file will be open in vi editer, Uncomment given line, These lines will look like this:

# passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;

# passenger_ruby /usr/bin/ruby;

uncomment these lines and update the path mentioned in the passenger_ruby line and add default user :

passenger_default_user root;

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;

passenger_ruby /usr/local/rvm/gems/ruby-2.3.0/wrappers/ruby;

Note if you are unable to get what is your path to ruby then follow these steps:

tecorb@tecorb-Lenovo-B40-80:~$   which passenger-config

this will return a path like: /usr/bin/passenger-config

If you are on RVM and use Ruby 2.2.1 (version can be whatever you are using)

tecorb@tecorb-Lenovo-B40-80:~$  rvm use 2.3.0

Now finally, we will invoke passenger-config with its full path, passing –ruby-command as parameter like:

tecorb@tecorb-Lenovo-B40-80:~$  /usr/bin/passenger-config –ruby-command

This will show you something like:

  To use in Apache: PassengerRuby /usr/local/rvm/wrappers/ruby-1.8.7-p358/ruby

  To use in Nginx : passenger_ruby /usr/local/rvm/wrappers/ruby-1.8.7-p358/ruby

  To use with Standalone: /usr/local/rvm/wrappers/ruby-1.8.7-p358/ruby /opt/passenger/bin/passenger start

From here you will get path for your passenger_ruby (Nginx). This path will use at passenger_ruby in nginx.conf

Now finally we will save our file and exit by Press ESC then type :wq and hit enter.

Step 5- Now we have almost done, we need to disable the default Nginx configuration at Nginx config file:

tecorb@tecorb-Lenovo-B40-80:~$  sudo vim /etc/nginx/sites-available/default

Findout these lines and comment them:

# listen 80 default_server;

# listen [::]:80 default_server ipv6only=on;

Save this config file, Press ESC then type :wq and hit enter.

Step 6- Now we will create an Nginx configuration file for our application (like our app name is tecorbapp):

tecorb@tecorb-Lenovo-B40-80:~$  sudo vim /etc/nginx/sites-available/tecorbapp

Add the following server block into this file:

server {

  listen 80 default_server;


  passenger_enabled on;

  passenger_app_env development;

  root /home/rails/tecorbapp/public;


In this file we enable listening on port 80, set our domain, enable Passenger, set the application environment here we have used development environment and set the root to the public directory of our ruby on rails project.

If you don’t want to add your domain to the application, you can skip the server_name line from this file, or if you want to use any IP address you can replace with your ip address.

Now we will save this config file, Press ESC then type :wq and hit enter.

Step 7- Now finally we will create a symlink this file:

tecorb@tecorb-Lenovo-B40-80:~$   sudo ln -s /etc/nginx/sites-available/tecorbapp /etc/nginx/sites-enabled/tecorbapp

and Restart our Nginx:

tecorb@tecorb-Lenovo-B40-80:~$  sudo nginx -s reload

Now our application should be accessible from our domain, go to your browser and hit the domain.

About UICollectionView in IOS

UICollectionView, Manages an ordered collection of data item and present them using customizable layouts.

UICollectionView is same as the UITableView. UITableView manages a collection of data or information and display then on the screen in a single column layout whereas UICollectionView offers developers flexibility to present item using customize layout.

UICollectionView has three components:-

  1. Cell:

It is an instance of UICollectionViewCell . It represent a single item in the data collection.

  1. Supplementary views:

It is optional and usually used to implement the header or footer view of the sections.

  1. Decoration views:

It is another type of supplementary view but for decoration purpose only. It is not related to data collection. We create decoration view to enhance the visual appearance of the CollectionView.

Step 1:

Open the Excode and select the Single View Application.

UI Collection View

Step 2:

Create project with “ExCollectionView” name.


Step 3:

Open the StoryBoard and there is a ViewController and drag the CollectionVIew inside the ViewController .

And set the Add New Constraints.


Step 4:

Select now the cell inside the UIViewController and add the UIImage in the UICollectionView cell and also set the UIImage constraints.



And open the ViewController.swift and add the extension of  UICollectionViewDataSource,UICollectionViewDelegatein the ViewCollection.swift.

And these three method in the ViewController.swift:

func numberOfSections(in collectionView: UICollectionView) -> Int {



    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {



    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) ->      UICollectionViewCell {




After that select the UICollectionViewCell and set the name of the reuseIdentifier = “MyCollectionViewCell”

Using Assistant Editor, add an IBOutlet to CollectionView in ViewController.swift

@IBOutlet weak var collectionView: UICollectionView!

Create a new Cocoa Touch Class file (File > New > File… > iOS > Cocoa Touch Class). Name it MyCollectionViewCell. This class will hold the outlets for the views that you add to your cell in the storyboard.


And open the ViewController.swift and add this code in the numberOfItemInSection in collectionview:


And go to the main story board and select the UIImage and set the image in the UIImage.


And also add one method in the viewcontroller.swift:

  func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout:    UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {

        return (indexPath.section == 0) ? CGSize(width: collectionView.bounds.size.width, height: 200) : CGSize(width: collectionView.bounds.size.width/2 – 2, height: 170)


And after the execude your code


It should be look like this. If you want to add multi image in the UIImageView then you use the array and pass the image in the array and cell in the cellForRowAtIndexPath method.

MVP (Minimum Viable Product) Part- 1

Over the past few years, minimum viable product (MVP) have begun to evolve

What is MVP?

Minimum Viable Product is development technique where fresh product or a website is being launched along with minimum resources in order to satisfy the tech-savvy or early adopters. The complete set of features is designed and developed after getting the feedback from the initial users about product that had already been launched. Through this initial version of product developers gather enough learning about product used by customers by applying least effort.

Importance of MVP

MVP is required to get data from customers regarding the product launch. When all the required data had been gathered then we move forward to develop fully functional product.

1). Save time and money.

2). Engage investors.

3). Cross checking whether project is being developed according to user’s feedback.

4). Get to know about the present market behavior regarding product.

 MVP for Startups

It is really a cool idea for an entrepreneur organization to begin with something that won’t let them down. These are MVP building blocks that make up an application live without actually building it. As startup’s they need not to invest on development all they have to do is to focus on Wireframes, Mockups, Explanatory Video or Rapid Prototype. This will give them a basic idea to release their initial model without wasting time and money. Being an entrepreneur one needs to think about having maximum output by providing minimum input features.

All the famous startups such as Facebook, Twitter, Dropbox, Zappos, Aardvark had just an idea that had been converted into live project. It’s all up to you, how well you can use the existing technology to build newer one. Get set and hit unless and until you achieve your destiny.  

 Factual MVP (Minimum Viable Product)

The basis: Associate participant could be a thanks to get the foremost bang for your buck once you’re promoting a replacement product construct.

So, you invest the smallest amount of cash and energy attainable to present your product plan a market check run so as to check if your target market is even remotely interested

 “The main concept of MVP is to sell product to market.”

 If they so no interest towards your concept, you only made a little investment. But if they are interested them it is green light to build a more sustainable product.

There are many building blocks to develop MVP, but I will talk about few of them.


Building blocks of MVP (Minimum Viable Product)

 1). Wireframes

 These are best choice if you are running out of time and money. You are explaining your product to tech-laden or creative audience. If your target are people who have real interest then MVP is best choice. It is based on visual concept. Apart from that if your aim is to present it to different audience that are not from above category then you need graphical or more enhance view of MVP. (Minimum Viable Product)

2). Rapid-Prototype

Other than that there are times that you need things that move, an eye catching stuff that contain buttons and images to attract them. Basically you need to explain you audience that they are not working on actual product so that they may not get over distracted by the functional behavior. Rest rapid prototype are best for people who need a virtual or visual representation of their product.

 3). Explainer Video

It is better idea to create a video rather to develop a product. So why? By biggest advantage of making a video prototype will lead towards better explanation of product that will be developed. User will get whole working of product in few minutes. It had great advantage to present your product to potential user or investors who are really interested without really building the main product.

4). Mockups

These are safe when you are working with an audience who don’t have mental practice to visualize abstract concept. They are ready made design that will help your audience to get perfect match to meet their requirements accordingly. To have better effect you can build interactive mockups of product.
