Introduction In the fast-paced world of software development, efficiency and consistency are key. Docker, a powerful containerization platform, has revolutionized the way we build, ship, and run applications. In this tutorial, we show you how to get started with Docker. Step 1: Install Docker (if not already installed) First of...
Introduction Power BI comes with the powerful formula language Data Analysis Expression (DAX) which allows the implementation of custom calculations. There are numerous operators and functions available in DAX. One essential DAX function is the IF function which is used for conditional calculations. In this tutorial, we will explore the...
Introduction PostgreSQL is one of the most widely used database management systems. One of the easiest ways to use PostgreSQL on macOS is the Postgres.app. Postgres.app provides a simple interface for setting up a server and a command-line interface (psql) for interacting with databases via the terminal.

Introduction One of the key tasks in data analysis is grouping data to gain insights and make informed decisions. In this tutorial, we will show you how to group the rows of a Pandas DataFrame and apply different aggregations on the grouped data. In order to do this, we will...
Introduction In 1997, Sepp Hochreiter and Jürgen Schmidhuber introduced Long Short-Term Memory (LSTM), a special type of Recurrent Neural Network (RNN). The motivation was to overcome the problems of traditional RNNs when dealing with long sequences. This is exactly what LSTM Networks (LSTMs) are supposed to do. The special architecture...
Introduction Power BI offers with the Power Query Editor a powerful tool for cleaning and transforming data. One important part of data preparation is filtering your data. Filtering enables you to sort out irrelevant data and to reduce your amount of data. In this tutorial, we show you how to...
Introduction In the landscape of software development, Docker has emerged as a game changer, offering a streamlined approach to building, shipping, and running applications. In this blog post, we explain the fundamental concept of Docker focusing on Dockerfiles, Docker images, and containers. What is Docker? Docker is an open-source platform...
Introduction One of the key tasks in data analysis is grouping data to gain insights and make informed decisions. In this tutorial, we will show you how to group the rows of a PySpark DataFrame and apply different aggregations on the grouped data. In order to do this, we will...
Introduction Data comes in different forms, each with its own characteristics and challenges. Basically, there are three main categories of data: Structured, Semi-structured and Unstructured Data. In this tutorial, we explore the characteristics and some examples for each kind of data. Structured Data First, let's have a look...
