AJAX Progrraming

Ajax , shorthand for Asynchronous JavaScript and XML , is a web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user requests a change. This is meant to increase the web page's interactivity, speed, and usability. The Ajax technique uses a combination of: XHTML (or HTML) and CSS, for marking up and styling information. The DOM accessed with a client-side scripting language, especially JavaScript and JScript, to dynamically display and interact with the information presented. The XMLHttpRequest object is used to exchange data asynchronously with the web server. In some Ajax frameworks and in certain situations, an IFrame object is used instead of the XMLHttpRequest object to exchange data with the web server, and in other implementations, dynamically added tags may be used.

Nutch crawler and integration with Solr

Before moving ahead with this article, I assume you have Solr installed and running. If you would like to install Solr on windows, mac or via docker, please read Setup a Solr instance . There are several ways to install nutch which you can read from Nutch tutorial , however I have written this article for those who would like to install nutch using docker. I tried finding help on google but could not find any help for nutch installation using docker and spent good amount of time fixing issues specific to it. Therefore I have written this article to help and save time of other developers. Install nutch using docker- 1. Pull docker image of nutch using below command, > docker pull apache/nutch 2. Once image is pulled, run the container, > docker run -t -i -d --name nutchcontainer apache/nutch /bin/bash 3. You should be able to enter in the container and see bash prompt, > bash-5.1# Let's setup few important settings now- 1. Goto bin folder, > bash-5.

The noblest pleasure is the joy of understanding
