Load Runner

*#Load Runner*

Load Runner is one of the widely used proprietary performance testing tool. The tool is designed to generate a specific load on the application.

During this phase, it can be determined how the application behaves under different load conditions.

Measuring system behavior and performance under load.Supports a wide range of apps.

Continuous testing - Integrate load testing into your development tools: IDE, jUnit, nUnit, Jenkins, Selenium and Microsoft Visual Studio.

Root cause analytics that leverage application-layer and code-level data.

Load Runner can simulate thousands of users concurrently by generating messages between application components or by simulating interactions with the user interface such as key presses or mouse movements.
The messages and interactions to be generated are stored in scripts.

Note: HPE acquired Load Runner as part of its acquisition of Mercury Interactive in November
In Sept HPE announced it is selling its software business, including Mercury products, to Micro Focus.

As of Sept 2017 the acquisition was complete.

Maven

*Q.* What’s the purpose of Maven settings.xml

*A.* One, we have pom.xml – which is part of the project itself. It is accessible to all. It contains “project information” that's necessary to build it - mainly all the dependencies.

So what is settings.xml  ?

Usually saved in ${user.home/.m2/settings.xml  is your system and/or user configuration – your local system configs and your user info.

And what is system/user configuration?

The path to your local repository, some maven preferences (e.g. interactive mode, offline, use Plugin Registry), configuration for different proxy profiles, server-specific settings (remote repository servers and the authentication info), download mirrors for repositories, build profiles and plugin Groups (group Ids to search for a plugin).

Since it contains personalized configs, the settings.xml file should not be bundled to any specific project, or distributed to an audience. Simply stated - settings.xml file is user-specific (private) whereas pom.xml is project-specific (public).

#Git | Version Control

Git is a free and open source distributed version control system for tracking changes in files and coordinating work on those files among multiple people.
It is designed to handle everything from small to very large projects with speed and efficiency.

Git is a mature, actively maintained open source project originally developed in
2005 by Linus Torvalds, the famous creator of the Linux operating system kernel.

A staggering number of software projects rely on Git for version control, including commercial projects as well as open source.
Trivia – Git is not an acronym. ‘git’ is British slang for a dumb, annoying, or generally unpleasant person.

The joke is that Linus Torvalds (Linux creator) names his projects after himself, so he chose ‘git’ as the name of the SCM he made.

ONE MINUTE OF SITTING

Even one minute of sitting without doing anything, no thought is stirred inside you, all is utterly silent – ONE INCH OF BUDDHA.

You have found at least one inch of Buddha hood. And you don’t need much more. Each moment, go on. And whatever you have found will also go on growing.

From one inch to one yard, and from one yard to one mile, and from one mile to one light year, and it will go on and on.

Buddha hood is a pilgrimage which ends nowhere. And what is the meaning of sitting?

Like lightning, all thoughts come and pass; you just remain watchful.

Don’t make any judgment or identification.

Just like lightning, let them come and go. You remain in your depths, just silent and witnessing, and you will be surprised:

nothing else has ever been, except your inner depth. Your innermost silence is the stuff existence is made of. 

Sahi

Sahi is an automation testing tool for web applications which comes as both open-source and feature-rich proprietary version. It provides the facility of record play back.

It supports Java and JavaScript. Sahi's core parts include the Sahi proxy server and the JavaScript engine. Sahi runs as a proxy server and the browser's proxy settings are configured to point to Sahi's proxy.

It then injects JavaScript event handlers into web pages, which allows it to record and playback events on the browser. Using a proxy makes Sahi independent of the browser used.

Sahi's APIs do not depend much on the HTML structure. Sahi does not use XPaths and has APIs like _near, _in etc. to help finding one element in relation to another.

Even if the structure of the page changes, these work properly. It easily automates applications built using ExtJS, ZK, Dojo, YUI or any other framework with an excellent recorder, smart object identification, simple scripting, automatic waits and inbuilt reports, Sahi gives the tester a powerful yet simple tool to accomplish testing across various browser and OS combinations.

Hadoop

*#Hadoop*

Apache Hadoop is an open-source java-based software framework used for distributed storage and processing of dataset of big data using the MapReduce programming model.

Hadoop services provide for data storage, data processing, data access, data governance, security, and operations.

The core of Apache Hadoop consists of a storage part, known as Hadoop Distributed File System (HDFS), and a processing part which is a MapReduce programming model.

It provides massive storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs.

Note: Hadoop is not a database or a single program, tool or application. It's a set of projects with a common goal integrated under one term Hadoop.

I rose again

I rose again , I rose again,

Deep from the pain

I rose again I rose again

From stars not too far

I rose again I rose again

Unknown to the known

I rose again I rose again

No whisper still a melody

No sadness yet melancholy

Unaware and passive yet whole

Piles of memories through the same doors

I rose again I rose again
