  Introduction Overview Installation One of the ways of installing ELK stack, as per my personal preference is not to use the Installer Wizard, rather download the corresponding zip from ElasticSearch  and start the services via command line Elastic Search: Download the latest version. Logstash:  Download  the latest version. Kibana:  Download  the latest version. Filebeat:  Download  the latest version. For Logstash, Kibana, and Filebeat the configuration file plays an important role and the input & output should be provided for Logstash and Filebeat. And for Kibana, the elastic search cluster details to which it should be listening. Once successfully started these applications as service, navigate to  http://localhost:9200  for fetching the elastic search cluster details. http://localhost:5601 for viewing the Kibana. First Run For configuring ELK Stack for the below flow diagram: Use the configure files as per my Github project: EL...

Java Starter Kit #1 Overview In Java POV, the collection framework gives us a wide range of data structures to choose from. Among them, one of the legacies yet widely used data structure is Linked List . The major Pros of Linked List come into play when the data structures need to store a huge amount of values or when the length is not definite. This is the time when this implementation of collection shines. The insertion and deletion of elements from LL are faster than other data structures.  Unlike array which again is a popular implementation of List interface in Java, LL doesn't store data in a continuous manner. Some other pros include: - Zero Memory Wastage: when an element is inserted or deleted, the allocation of memory is dynamic. When removed the previously-stored node reference is removed as hence GC clears it. And when inserted it allocates a new node when it is inserted and doesn't pre-occupy any space in the heap at the initialization of LL. Linked Lis...

Ya  Continous Integration  is the exact thing I am talking about. Jenkins is the most popular CI-CD tool available out in the market nowadays. As always to kick-start a new tool the official documentation is good but not the ideal solution as it can be a bit high level.

Well, I am a big fan of documentation and the reason for the same is not because I know a lot, the reason for the same is that I don't know a lot! Fact ! There are a lot of misconceptions that Agile Methodology is against Documentation. Working software over comprehensive documentation The above statement in Agile Manifesto states the importance of documentation in a project, but the real interception of the statement is often described incorrectly. It means you should create documentation that provides value and at the same time does not hinder the team’s progress. Agile document requirements are user stories, which are sufficient for a software developer to begin the task of building a new function. Major advanatages of documentations are: A single source of truth saves time and energy. Determine what others need to know about the product/services provided by us. The hiring and onboarding process can be easier. Enables Revision Control and provides a proper process for updates. S...
