The quickest and easiest way to analyze NumPy arrays is by using the numpy.array() method. This method allows you to quickly and easily analyze the values contained in a numpy array. This method can also be used to find the sum, mean, standard deviation, max, min, and other useful analysis of the value contained within a numpy array. Sum You can find the sum of Numpy arrays using the np.sum() function.  For example:  import numpy as np  a = np.array([1,2,3,4,5])  b = np.array([6,7,8,9,10])  result = np.sum([a,b])  print(result)  # Output will be 55 Mean You can find the mean of a Numpy array using the np.mean() function. This function takes in an array as an argument and returns the mean of all the values in the array.  For example, the mean of a Numpy array of [1,2,3,4,5] would be  result = np.mean([1,2,3,4,5])  print(result)  #Output: 3.0 Standard Deviation To find the standard deviation of a Numpy array, you can use the NumPy std() function. This function takes in an array as a par

Ruby on Rails: How to Create Web Application

-
You’ve probably already used many of the applications that were built with Ruby on Rails: Basecamp, GitHub,Shopify, Airbnb, Twitch, SoundCloud,Hulu, Zendesk, Square, Highrise. Those are just some of the big names, but there are literally hundreds of thousands of applications built with the framework since its release in 2004.


Ruby on Rails is open source software, so not only is it free to use, you can also help make it better. More than 4,200 people already have contributed code to Rails. It’s easier than you think to become one of them.

Optimizing for programmer happiness with convention over configuration is how we roll. Ruby on rails has been popularizing both concepts along with a variety of other controversial points since the beginning.


To learn more about why rails is so different from many other web-application frameworks and paradigms, examine the rails doctrine rails is a web application development framework written in the ruby language. 

It allows you to write less code while accomplishing more than many other languages and frameworks.


It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. How to create ruby on rails sample application: click here

How to Decode TLV Quickly

TLV format contains three parts Tag, Length, and value. In a credit card or financial transactions, the TLV protocol supports this format. Below, you will find the ideas to decode TLV data quickly.  According to IBM , the tag tells what type of data it is. The length field denotes the length of the value. The value-field denotes the actual value. Structure of TLV. TLV comprises three field values. Tag Length Value How to Decode TLV The EMV labs developed tags which in turn part of EMV protocol. Each tag has an unique meaning. And the Tag and Length together takes 1 to 4 bytes of memory. 1. The Best example for TLV. Below is the way to decode the EMV tag. The first part of the TLV format is TAG. The second part is LENGTH, and finally the VALUE. Syntax of EMV tag: [Tag][Value Length][Value] (ex. " 9F40 05 F000F0A001 ") where,  Tag Name =  9F40 Value Length (in bytes) =  05  Value (Hex representation of bytes. Example, "F0" – 1-byte) =  F000F0A001 Finally, what is 9F40

Store public or private data. Host a static website. These websites use client-side technologies (such as HTML, CSS, and JavaScript) to display content that doesn't change frequently. A static website doesn't require server-side technologies (such as PHP and ASP.NET). Host a dynamic website or web app. These websites include classic three-tier applications, with web, application, and database tiers. Support students or online training programs. Process business and scientific data. Handle peak loads. AWS Quest
