The need for every professional to have a solid presence on the Internet is more important than ever before. Having a presence beyond an email account, such as a custom web page or web application, usually requires a clumsy assortment of outside services or hiring a dedicated administrator. Thus it is more sensible for the average professional to become adept at managing their own private server. 

In Set Up and Manage Your Virtual Private Server, author Jon Westfall expertly designs interesting, understandable lessons for professionals such as teachers, doctors, lawyers, and more to deploy their own virtual private server. He walks you through choosing the right service and customizing it for your specific business or personal needs, and does this with great ease while instilling invaluable knowledge.  Basics such as setting up users, managing security and firewalls, installing and updating software, and troubleshooting by reviewing log files, backing up data, and so much more.

Set Up and Manage Your Virtual Private Server equips you with the power of knowledge to set your web presence apart from the rest. You now have complete control over your virtual brand that is your own—separate from any employer or affiliate. Your career mobility is in your hands with the ability to run your own private server at your fingertips. The digital era centers this technical literacy and independence as a critical skillset.

• Understand basic server terminology and the way servers operate and are networked together
• See how software is used on a server and its role (for example, Linux, Apache, MySQL, PHP, and so on)
• Get comfortable with the basic command-line operation of a virtual private server to set up users, manage security and firewalls, install software, update software, and troubleshoot by reviewing log files
• Store and back up important information
• Identify, analyze, and deploy open-source software products that can enhance productivity

Use R 4, RStudio, Tidyverse, and Shiny to interrogate and analyze your data, and then use the D3 JavaScript library to format and display that data in an elegant, informative, and interactive way. You will learn how to gather data effectively, and also how to understand the philosophy and implementation of each type of chart, so as to be able to represent the results visually.

With the popularity of the R language, the art and practice of creating data visualizations is no longer the preserve of mathematicians, statisticians, or cartographers. As technology leaders, we can gather metrics around what we do and use data visualizations to communicate that information. Pro Data Visualization Using R and JavaScript combines the power of the R language with the simplicity and familiarity of JavaScript to display clear and informative data visualizations.

Gathering and analyzing empirical data is the key to truly understanding anything. We can track operational metrics to quantify the health of our products in production. We can track quality metrics of our projects, and even use our data to identify bad code. Visualizing this data allows anyone to read our analysis and easily get a deep understanding of the story the data tells. This book makes the R language approachable, and promotes the idea of data gathering and analysis mostly using web interfaces.

What You Will Learn

• Carry out data visualization using R and JavaScript
• Use RStudio for data visualization 
• Harness Tidyverse data pipelines
Apply D3 and R Notebooks towards your data
• Work with the R Plumber API generator, Shiny, and more

Who This Book Is For

Programmers and data scientists/analysts who have some prior experience with R and JavaScript.

Get started with an accelerated introduction to the R ecosystem, programming language, and tools including R script and RStudio. Utilizing many examples and projects, this book teaches you how to get data into R and how to work with that data using R. Once grounded in the fundamentals, the rest of Practical R 4 dives into specific projects and examples starting with running and analyzing a survey using R and LimeSurvey. Next, you'll carry out advanced statistical analysis using R and MouselabWeb. Then, you’ll see how R can work for you without statistics, including how R can be used to automate data formatting, manipulation, reporting, and custom functions.

The final part of this book discusses using R on a server; you’ll build a script with R that can run an RStudio Server and monitor a report source for changes to alert the user when something has changed. This project includes both regular email alerting and push notification. And, finally, you’ll use R to create a customized daily rundown report of a person's most important information such as a weather report, daily calendar, to-do's and more. This demonstrates how to automate such a process so that every morning, the user navigates to the same web page and gets the updated report.

What You Will Learn

Who This Book Is For 

With Beginning Android Web Apps Development, you'll learn how to apply HTML5, CSS3, JavaScript, Ajax and other Web standards for use on the Android mobile platform, by building a variety of fun and visually stimulating games and other web applications! If you've done some basic web development, and you want to build your skills to create exceptional web apps, you'll find everything you seek in the discussions and examples in this book.

Each application you'll build in Beginning Android Web Application Development will show you solutions that you can apply to many of your own projects. Each example shares techniques and coding solutions that will inspire your own work. You'll learn how to tie your Android apps into Twitter through two apps that you'll build: Who's that Tweet?!, a quiz game based on celebrity accounts, and I Love Ham, a coding investigation into search phrases and rhyming.

Your Android web app development skills will then proceed in another direction, as you discover the power of HTML5 in two game apps: Scavenger Hunt, which introduces you to the HTML5 GPS location API, and Spies!, a location-based application that shows you how to use CSS3, Ajax, and HTML5 within multi-player environments. You'll also create an Android web application which checks the arrival time of buses and light-rails through the use of Portland, Oregon's open Tri-Met data API! This app is a great template for other apps you may want to build in the future, and showcases the important techniques for incorporating cloud-based apps into web games. After reading Beginning Android Web Apps Development, you will have built real apps and developed along the way the skills you'll need to create highly interactive, professional web applications... and, your journey will be engaging and enjoyable!
