Providing Technology Training and Mentoring For Modern Technology Adoption
1.1 The Traditional Client–Server Processing Pattern It is good for small-to-medium data set sizes. Fetching 1TB worth of data might take longer than 1 hour. 1.2 Enter Distributed Computing We need a new approach — distributed computing where processing is done on clusters of computers. But there are challenges like Process (Software) / Hardware failures,
1.1 Data is King Data is king and it outlives applications. Applications outlive integrations. Organizations striving to become data-driven need to institute efficient, intelligent, and robust ways for data processing. Data engineering addresses many of the aspects of this process. 1.2 Translating Data into Operational and Business Insights Success of organizations is predicated on their ability to convert raw
This tutorial is adapted from Web Age course Introduction to Angular 8 Programming. In this tutorial, we will develop a very simple single page application (SPA) using the Angular Component Router module. The main goal will be to understand how routing works. We will keep the business logic very simple. Part 1 – Get Started 1.
This tutorial is adapted from Web Age course Comprehensive Angular 8 Programming. 1.1 What is Material Design (MD)? Material Design is design language developed by Google. It was released in 2014 and incorporated into the Android OS. It is also available for other platforms (Angular, Web, iOS, Flutter, …). Developers can achieve uniformity in their applications

1.1 What is Spark Shell? The Spark Shell offers interactive command-line environments for Scala and Python users. SparkR Shell has only been thoroughly tested to work with Spark standalone so far and not all Hadoop distros available, and therefore is not covered here. The Spark Shell is often referred to as REPL (Read/Eval/Print Loop).The Spark Shell session
1.1 What is Apache Spark? Apache Spark (Spark) is a general-purpose processing system for large- scale data. Spark is effective for data processing of up to 100s of terabytes on a cluster of machines. It runs on both Unix-like systems and Windows. Main players behind Spark are Apache Software, Databricks (founded by the creators of Spark), UC
