In this course, we will start from scratch. This is a very applied course, so we will immediately start with the command line! We will explain everything through the commands and not bore you with dull slides. In fact, there isn't a single slide in this course! After taking this course, you will be all set to work with highly useful concepts such as Linux System Administration, setting up architectures for Machine Learning and Deep Learning, work with systems that enable VoIP and many many more areas. If you have never worked with Linux before (or installed it), this course will show you how to set it up in a Virtual Machine with minimal effort. If you already have Linux or Mac, you can use that too. Then, we will start from zero and get you up to the level of expert without dumping too many commands on you. We take a case study-based approach and motivate why we need the commands we're learning. If there is a command that is typically taught in courses but isn't used too often, we skip it so that you learn only the stuff that will be useful to you. In this course, we aim to give you the feel of the rhythm behind the command line so that you are in the position to understand the philosophy behind the command line and use it to your advantage. Through this approach, we can cover the whole spectrum in less than 3 hours.
