Beginning R 4
Learn how to use R 4, write and save R scripts, read in and write out data files, use built-in functions, and understand common statistical methods. This in-depth tutorial includes key R 4 features including a new color palette for charts, an enhanced reference counting system (useful for big data), and new data import settings for text (as well as the statistical methods to model text-based, categorical data). Each chapter starts with a list of learning outcomes and concludes with a summary of any R functions introduced in that chapter, along with exercises to test your new knowledge. The text opens with a hands-on installation of R and CRAN packages for both Windows and macOS. The bulk of the book is an introduction to statistical methods (non-proof-based, applied statistics) that relies heavily on R (and R visualizations) to understand, motivate, and conduct statistical tests and modeling. Beginning R 4 shows the use of R in specific cases such as ANOVA analysis, multiple and ...

Just Enough Linux
If you've toyed with Linux and never really caught on to what's happening or have used a graphical interface without really touching the command line this book is for you. The idea is to get you started on the process of using some of the commands available in Linux so that you: Feel comfortable running commands; You understand a little more about what Linux is about; Most importantly, you start to get Linux. It's not written for experts. It's put together as a guide to get you started if you're unsure about how to make the first move. Although it's examples are centered around using Linux with a Raspberry Pi, the commands you learn here will translate to an industrial server running Linux. ...

The Coder's Apprentice
The Coder's Apprentice is a course book, written by Pieter Spronck, that is aimed at teaching Python 3 to students and teenagers who are completely new to programming. Contrary to many of the other books that teach Python programming, this book assumes no previous knowledge of programming on the part of the students, and contains numerous exercises that allow students to train their programming skills. The goal of this book is to teach anyone how to create useful programs in Python. It should be usable by secondary school students, and university and college students for whom computer programming is not naturally incorporated in their course program. Its aim is to give anyone the means to become proficient in programming, and as such get prepared to perform well in the 21st century job market. ...

Category Theory for Programmers
Category Theory is one of the most abstract branches of mathematics. It is usually taught to graduate students after they have mastered several other branches of mathematics, like algebra, topology, and group theory. It might, therefore, come as a shock that the basic concepts of category theory can be explained in relatively simple terms to anybody with some experience in programming. That's because, just like programming, category theory is about structure. Mathematicians discover structure in mathematical theories, programmers discover structure in computer programs. Well-structured programs are easier to understand and maintain and are less likely to contain bugs. Category theory provides the language to talk about structure and learning it will make you a better programmer. ...

Linux Containers and Virtualization
Get a novel perspective on Linux containers and understand the world of virtualization. This book takes you down the rabbit hole to discover what lies below the API. You'll go on a journey of virtualization and see how containers are realized in the Linux world. Linux Containers and Virtualization details the data structures within the Linux kernel which make up Linux containers. You will start with the fundamentals of virtualization including how different resources such as memory, CPU, network, and storage are virtualized.
