CompTIA Linux+ XK0-005 Cert Guide from Pearson IT Certification helps you prepare to succeed on the CompTIA Linux+ exam by directly addressing the exam’s objectives as stated by CompTIA. Leading instructor and expert Ross Brunson shares preparation hints and test-taking tips, helping you identify areas of weakness and improve both your conceptual knowledge and hands-on skills. Linux is a great operating system, useful for a large variety of tasks, but also with a lot of tweakable and configurable options, some of which are not that well documented, or easy to understand. It's like buying a car off the car dealer's lot, if you just start it up and drive it, it's pretty simple, just avoid crashing and keep the fluids full and you'll be ok for a while. The REAL fun begins when something doesn't work right, you have to pop the hood (or bonnet for our European friends) and start figuring out what went awry or what needs changed. Linux can be very easy to use, but also allows you to dive s deep under the hood into the inner workings as you could possibly want to. The Chapter 1 is all about the essentials of Linux System Management, including information about what the Filesystem Hierarchy Standard is, what files and directories go where and contain what, particulars about the /dev directory and it's contents, the basics of storage management including types of storage, partition types, RAID and FUSE, the boot process of a Linux system and constructing software packages from source.

This book covers smart grid applications of various big data analytics, Artificial Intelligence, and Machine Learning technologies for demand prediction, decision-making processes, policy, and energy management. The book delves into new technologies such as the Internet of Things, BlockChain for smart home solutions, and smart city solutions in depth in the context of modern power systems. Implementing Big Data science for better and safer operation is possible in the context of future smart energy system’s digitization and automation. Smart plugs, switches, devices, smart grids, smart appliances, phase measurement, field measurement, RTUs, sensors mounted on grid-level equipment (e.g., transformers and network switches), asset inventory, SCADA system, geographic information system (GIS), weather data, traffic data, and social media are all expected to become massive data sources. This book covers real-time monitoring, control, and automation utilizing AI to access and extract data features. Big Data analytics is an area that has shown promising results in handling complex problems such as electricity demand forecasting. This book chapter explores the advancements in forecasting techniques of electrical demand. These advancements are explored via survey of existing literature, demonstration of techniques, and a comparative analysis of performance of Machine Learning techniques. Machine Learning techniques, viz. linear regression (LR), polynomial regression (PR), ridge regression (RR), least absolute shrinkage and selection operator (LASSO) regression, decision tree regression (DTR), random forest regression (RFR), and K nearest neighbor regression (KNNR) are demonstrated and discussed.

Written by Matt Taddy, successful author of the McGraw Hill Professional title, Business Data Science graduate of University of Chicago and Amazon Chief Economist. This new higher-ed text takes a practical, modern approach to Data Science and business analytics for the graduate-level business analytics student or professional. It takes a learn-by-doing approach, with real data analysis examples that explain the "why", rather than the "what" in the decision-making discussions. It uses R as the primary technology throughout the text and includes an end-of-chapter reference to the basic R recipes in each chapter. The text uses tools from economics and statistics in combination with Machine Learning Techniques to create a platform for using data to make decisions. The practice of data analytics is changing and modernizing. Innovations in computation and Machine Learning are creating new opportunities for the data analyst: exposing previously unexplored data to scientific analysis, scaling tasks through automation, and allowing deeper and more accurate modeling. Spreadsheet models and pivot tables are being replaced by code scripts in languages like R and Python. There has been massive growth in digitized information, accompanied by development of systems for storage and analysis of this data. There has also been an intellectual convergence across fields - Machine Learning and Computer Science, statistics, and social sciences and economics - that has raised the breadth and quality of applied analysis everywhere. This is the Data Science approach to analytics, and it allows leaders to go deeper than ever to understand their operations, products, and customers.

Mastering SQL helps readers gain a firm understanding of the Structured Query Language. Structured Query Language, more often known as SQL, is the de facto standard language for working with databases. It is a specialized language for handling data-related tasks like creating a database, putting information into tables, modifying and extracting that information, and much more. MySQL, PostgreSQL, Oracle, SQL light, etc. are only a few examples of SQL implementations. Structured Query Language (SQL) is a query language for working with relational databases. We can use SQL to update, delete, and retrieve data from a database. A table is used to define the data/object. These tables consist of rows and columns and are uniquely identified by their field names. SQL is a fast and efficient database system. SQL allows for the rapid and efficient retrieval of huge numbers of data entries from a database. It’s a relational database. Thus, data is described in a more orderly fashion than in an unstructured database like MongoDB. Insertions, deletions, inquiries, manipulations, and computations of data through analytical queries in a relational database may all be performed in a matter of seconds.

In the life sciences, data analysis is now part of practically every research project. Genomics, in particular, is being driven by new measurement technologies that permit us to observe certain molecular entities for the first time. These observations are leading to discoveries analogous to identifying microorganisms and other breakthroughs permitted by the invention of the microscope. Choice examples of these technologies are microarrays and next generation sequencing. This book will cover several of the statistical concepts and data analytic skills needed to succeed in data-driven life science research. We go from relatively basic concepts related to computing p-values to advanced topics related to analyzing high-throughput data. Throughout the book we will describe visualization techniques in the statistical computer language R that are useful for exploring new data sets. For example, we will use these to learn when to apply robust statistical techniques. While statistics textbooks focus on mathematics, this book focuses on using a computer to perform data analysis. Instead of explaining the mathematics and theory, and then showing examples, we start by stating a practical data-related challenge. This book also includes the computer code that provides a solution to the problem and helps illustrate the concepts behind the solution. By running the code yourself, and seeing data generation and analysis happen live, you will get a better intuition for the concepts, the mathematics, and the theory. The book was created using the R markdown language and we make all this code available to the reader.

With the rapid growth of big data and AI, organizations are quickly building data products and solutions in an ad-hoc manner. But as these data organizations mature, it's apparent that their analysis and Machine Learning (ML) models are only as reliable as the data they're built upon. The solution? Delta Lake, an open-source format that enables building a lakehouse architecture on top of existing storage systems such as S3, ADLS, and GCS. In this practical book, author Bennie Haelen shows data engineers, data scientists, and data analysts how to get Delta Lake and its unique features up and running. The ultimate goal of building data pipelines and applications is to query processed data and gain insights from it. You'll learn how the choice of storage solution determines the robustness and performance of the data pipeline, from raw data to insights. Delta Lake brings capabilities such as transactional reliability and support for UPSERTs and MERGEs to data lakes while maintaining the dynamic horizontal scalability and separation of storage and compute of data lakes. Delta Lake is one the enablers for building Data lakehouses, an open data architecture that combines the best of data warehouses and data lakes.
