The Quick and Easy Way to Analyze Numpy Arrays

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

Microsoft HDInsight for Hadoop Cluster

-
HDInsight is Microsoft's implementation of a Big Data solution with Apache Hadoop at its core. HDInsight is 100 percent compatible with Apache Hadoop and is built on open source components in conjunction with Hortonworks, a company focused toward getting Hadoop adopted on the Windows platform.

HDINSIGHT


HDInsight Microsoft


Initiate


Basically, Microsoft has taken the open source Hadoop project, added the functionalities needed to make it compatible with Windows (because Hadoop is based on Linux), and submitted the project back to the community. 


All of the components are retested in typical scenarios to ensure that they work together correctly and that there are no versioning or compatibility issues.


Features


Microsoft's Hadoop-based distribution brings the robustness, manageability, and simplicity of Windows to the Hadoop environment. 


The focus is on hardening security through integration with Active Directory, thus making it enterprise ready, simplifying manageability through integration with System Center 2012, and dramatically reducing the time required to set up and deploy via simplified packaging and configuration.


Security


These improvements will enable IT to apply consistent security policies across Hadoop clusters and manage them from a single pane of glass on System Center 2012. Further, Microsoft SQL Server and its powerful BI suite can be leveraged to apply analytics and generate interactive business intelligence reports, all under the same roof. 


Easy Deployment


For the Hadoop-based service on Windows Azure, Microsoft has further lowered the barrier to deployment by enabling the seamless setup and configuration of Hadoop clusters through an easy-to-use, web-based portal and offering Infrastructure as a Service (IaaS).


Microsoft is currently the only company offering scalable Big Data solutions in the cloud and for on-premises use. These solutions are all built on a common Microsoft Data Platform with familiar and powerful BI tools.


HDInsight is available in two flavors



1. Windows Azure HDInsight Service



This is a service available to Windows Azure subscribers that uses Windows Azure clusters and integrates with Windows Azure storage. 


An Open Database Connectivity (ODBC) driver is available to connect the output from HDInsight queries to data analysis tools.


2. Windows Azure HDInsight Emulator



This is a single-node, single-box product that you can install on Windows Server 2012, or in your Hyper-V virtual machines.

 
The purpose of the emulator is to provide a development environment for use in testing and evaluating your solution before deploying it to the cloud. 


You save money by not paying for Azure hosting until after your solution is developed and tested and ready to run. The emulator is available for free and will continue to be a single-node offering.

How to Decode TLV Quickly

-
Image
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

Here are seven amazing Infosys AWS interview questions for your quick reference. These are also asked in TCS. Infosys and TCS AWS interview questions 1). What is AWS? Amazon Web Services (AWS) provides on-demand computing resources and services in the cloud, with pay-as-you-go pricing. For example, you can run a server on AWS that you can log on to, configure, secure, and run just as you would a server that's sitting in front of you 2). What you can do with AWS? 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
