IT skills digital demand and popular areas to re-skill

The popular IT skills you need for digital age are — ML(Machine Learning), AR (Augumeneted reality), VR (Virtual reality), AI (Artificial intelligence) and IoT. That's machine learning, augmented reality, virtual reality, artificial intelligence, and Internet of Things.

Ramanujan who has been at TCS for 26 years has himself re-skilled several times — from COBOL to client-server to ERP to cloud, before moving into more stable managerial roles. But the reskilling he's witnessing now is like none he's seen before.

The Sqoop in Hadoop story to process structural data

Why Sqoop you need while working on Hadoop The Sqoop and its primary reason is to import data from structural data sources such as Oracle/DB2 into HDFS(also called Hadoop file system).

To our readers, I have collected a good video from Edureka which helps you to understand the functionality of Sqoop.

The comparison between Sqoop and Flume

The Sqoop the word came from SQL+Hadoop Sqoop word came from SQL+HADOOP=SQOOP. And Sqoop is a data transfer tool. The main use of Sqoop is to import and export the large amount of data from RDBMS to HDFS and vice versa. List of basic Sqoop commands Codegen- It helps to generate code to interact with database records.Create-hive-table- It helps to Import a table definition into a hiveEval- It helps to evaluateSQL statement and display the resultsExport-It helps to export an HDFS directory into a database tableHelp- It helps to list the available commandsImport- It helps to import a table from a database to HDFSImport-all-tables- It helps to import tables …

Four Tableau products a quick review and explanation

I want to share you what are the Products most popular.

Total four products. Read the details below.

Tableau desktop-(Business analytics anyone can use) - Tableau  Desktop  is  based  on  breakthrough technology  from  Stanford  University  that  lets  you drag & drop to analyze data. You can connect to  data in a few clicks, then visualize and create interactive dashboards with a few more.

We’ve done years of research to build a system that supports people’s natural  ability  to  think visually. Shift fluidly between views, following your natural train of thought. You’re not stuck in wizards or bogged down writing scripts. You just create beautiful, rich data visualizations.  It's so easy to use that any Excel user can learn it.

Machine learning and AI two different concepts why

Great to read this article. This is a summary of what I learnt from many books and magazines. Summary, I am going to present for you a quick guide. Let us come to the point...

The thoughts on AI...

Artificial Intelligence is the broader concept of machines being able to carry out tasks in a way that we would consider “smart”.

The theory in way back,

Very early European computers were conceived as “logical machines” and by reproducing capabilities such as basic arithmetic and memory, engineers saw their job, fundamentally, as attempting to create mechanical brains.

As progressing to new era the technology and understanding about our mind how it works caused creation of thoughts.

That thoughts now called as AI (Artificial Intelligence). The artificial intelligence comes in two parts. One is Applied AI and the other one Generalised AI.

When Applied AI
is far more common – systems designed to intelligently trade stocks and shares, or manoeuvre an autonomous vehicle would fall into this cate…

Run Scala on Java with these unique features

Let us start it in layman terms...

Why you need Scala...

The name Scala stands for “scalable language.” The language is so named because it was designed to grow with the demands of its users.

Where Scala can be applied...

You can apply Scala to a wide range of programming tasks, from writing small scripts to
building large systems.

The real use of Scala...
Scala is easy to get into. It runs on the standard Java platform and interoperates seamlessly with all Java libraries. It’s quite a good language for writing scripts that pull together Java components.But it can apply its strengths even more when used for building large systems and frameworks of reusable components. Technically, Scala is a blend of object-oriented and functional programming
concepts in a statically typed language.
The fusion of object-oriented and functional programming shows up in many different aspects of Scala; It is probably more pervasive than in any other widely used language. The two programming styles have comp…

DevOps quiz beginner questions useful for AWS job seekers

According to EDUREKA-DevOps is a philosophy, a cultural shift that merges operations with development and demands a linked toolchain of technologies to facilitate collaborative change.
Why DevOps needed... Since the DevOps philosophy is still at a very nascent stage, application of DevOps as well as the bandwidth required to adapt and collaborate, varies from organization to organization, yet we can talk about a winning formula of skills that can present you as a perfect candidate for any type of organization.

On top of fluency in web languages such as Ruby, Python, PHP or Java, the ideal DevOps engineer should have some experience using infrastructure automation tools like Chef, Puppet, Ansible, SaltStack or Windows PowerShell DSC.

I have given a quiz with 11 most poular questions. This is very useful to understand the concept of DevOps Quickly.

Top 8 AWS interview Questions for quick revision

Q1. Explain Elastic Block Storage? What type of performance can you expect? How do you back it up? How do you improve performance?
A1. EBS is a virtualized SAN or storage area network. That means it is RAID storage to start with so it’s redundant and fault tolerant. If disks die in that RAID you don’t lose data. Great! It is also virtualized, so you can provision and allocate storage, and attach it to your server with various API calls. No calling the storage expert and asking him or her to run specialized commands from the hardware vendor. Performance on EBS can exhibit variability. That is it can go above the SLA performance level, then drop below it. The SLA provides you with an average disk I/O rate you can expect. This can frustrate some folks especially performance experts who expect reliable and consistent disk throughput on a server. Traditional physically hosted servers behave that way. Virtual AWS instances do not. Backup EBS volumes by using the snapshot facility via API call …
