Cybersecurity for Space
This is the first book of its kind to cover the unique challenges of creating, maintaining, and operating a system that operates in both outer space and cyber space. It covers the impact that cyber threats can have on space systems and how the cybersecurity industry must rise to meet the threats.Space is one of the fastest growing military, government, and industry sectors. Because everything in today’s world exists within or connected to cyberspace, there is a dire need to ensure that cybersecurity is addressed in the burgeoning field of space operations.You will be introduced to the basic concepts involved in operating space systems that include low earth orbit (LEO), geosynchronous orbit (GEO), and others. Using the related high-level constraints, threats, and vectors, you will be able to frame a clear picture of the need and challenges of bringing cybersecurity to bear on satellites, space vehicles, and their related systems.The author, who has spent seven years in the US Marine Corps and was originally involved in satellite communications and later cyber operations, is now a seasoned cybersecurity practitioner currently implementing cybersecurity vision and strategy to a large portfolio of systems and programs, many focused specifically in space. A published academic and experienced professional, he brings a practical, real-world and tempered approach to securing space vehicles and their systems.WHAT YOU WILL LEARN* Understand what constitutes a space system and the challenges unique to operations of all spacecraft* Get introduced to various space vehicles and their unique constraints and challenges* Be aware of the physical and cyber threats to the space vehicle and its ability to fly and orbit* Know the physical and cyber vectors from which threats may manifest* Study the micro- and macro-analysis provided of space system attack scenarios* Be familiar with the high-level problems of cybersecurity in the space domainWHO THIS BOOK IS FORThis book is written for two audiences: those with a background in space operations as well as those in cybersecurity.

Modern Full-Stack Development
Explore what React, Node, TypeScript, Webpack, and Docker have to offer individually, and how they all fit together in modern app development.React is one of the most popular web development tools available today, and Node.js is extremely popular for server-side development. The fact that both utilize JavaScript is a big selling point, but as developers use the language more, they begin to recognize the shortcomings, and that’s where TypeScript comes in and why it’s gaining in popularity quickly. Add Webpack and Docker to the mix, and you’ve got a potent full development stack on which to build applications.You’ll begin by building a solid foundation of knowledge and quickly expand it by constructing two different real-world apps. These aren’t just simple, contrived examples but real apps that you can choose to install on your servers and use for real. By the end, you will have a solid grasp of building apps with React, Node.js, and TypeScript and a good grasp on how Webpack can be used to optimize and organize your code for deployment. You’ll also understand how Docker can be used to run the apps you build in a clear and well-defined way, all of which will be able to springboard you into creating more advanced apps on your own.WHAT YOU'LL LEARN* Get a project started and logically structure it* Construct a user interface with React and Material-UI * Use WebSockets for real-time communication between client and server* Build a REST API with Node and Express as another approach to client-server communication* Package the app with Webpack for optimized delivery* Take a completed app and wrap it up with Docker for easy distribution* Review a host of other ancillary topics including NPM, Semantic versioning, Babel, NoSQL, and moreWHO THIS BOOK IS FORWeb developers with basic knowledge of HTML, JavaScript, CSS, and CLI tools who are interested in and in all aspects of application development, and using TypeScript instead of straight JavaScript.FRANK ZAMMETTI is the author of 12 Apress titles on a variety of web and mobile development topics.

MySQL 8 Query Performance Tuning
Identify, analyze, and improve poorly performing queries that damage user experience and lead to lost revenue for your business. This book will help you make query tuning an integral part of your daily routine through a multi-step process that includes monitoring of execution times, identifying candidate queries for optimization, analyzing their current performance, and improving them to deliver results faster and with less overhead. Author Jesper Krogh systematically discusses each of these steps along with the data sources and the tools used to perform them.MYSQL 8 QUERY PERFORMANCE TUNING aims to help you improve query performance using a wide range of strategies. You will know how to analyze queries using both the traditional EXPLAIN command as well as the new EXPLAIN ANALYZE tool. You also will see how to use the Visual Explain feature to provide a visually-oriented view of an execution plan. Coverage of indexes includes indexing strategies and index statistics, and you will learn how histograms can be used to provide input on skewed data distributions that the optimizer can use to improve query performance. You will learn about locks, and how to investigate locking issues. And you will come away with an understanding of how the MySQL optimizer works, including the new hash join algorithm, and how to change the optimizer’s behavior when needed to deliver faster execution times. You will gain the tools and skills needed to delight application users and to squeeze the most value from corporate computing resources.WHAT YOU WILL LEARN* Monitor query performance to identify poor performers* Choose queries to optimize that will provide the greatest gain* Analyze queries using tools such as EXPLAIN ANALYZE and Visual Explain* Improve slow queries through a wide range of strategies* Properly deploy indexes and histograms to aid in creating fast execution plans* Understand and analyze locks to resolve contention and increase throughputWHO THIS BOOK IS FORDatabase administrators and SQL developers who are familiar with MySQL and need to participate in query tuning. While some experience with MySQL is required, no prior knowledge of query performance tuning is needed.JESPER WISBORG KROGH has worked with MySQL databases since 2006 both as an SQL developer, a database administrator, and for more than eight years as part of the Oracle MySQL Support team. He has spoken at MySQL Connect and Oracle OpenWorld on several occasions, and addition to his books, he regularly blogs on MySQL topics and has authored around 800 documents in the Oracle Knowledge Base.

PostgreSQL Configuration
Obtain all the skills you need to configure and manage a PostgreSQL database. In this book you will begin by installing and configuring PostgreSQL on a server by focusing on system-level parameter settings before installation. You will also look at key post-installation steps to avoid issues in the future. The basic configuration of PostgreSQL is tuned for compatibility rather than performance. Keeping this in mind, you will fine-tune your PostgreSQL parameters based on your environment and application behavior. You will then get tips to improve database monitoring and maintenance followed by database security for handling sensitive data in PostgreSQL.Every system containing valuable data needs to be backed-up regularly. PostgreSQL follows a simple back-up procedure and provides fundamental approaches to back up your data. You will go through these approaches and choose the right one based on your environment. Running your application with limited resources can be tricky. To achieve this you will implement a pooling mechanism for your PostgreSQL instances to connect to other databases. Finally, you will take a look at some basic errors faced while working with PostgreSQL and learn to resolve them in the quickest manner.WHAT YOU WILL LEARN* Configure PostgreSQL for performanceMonitor and maintain PostgreSQL instances * Implement a backup strategy for your dataResolve errors faced while using PostgreSQLWHO THIS BOOK IS FORReaders with basic knowledge of PostgreSQL who wish to implement key solutions based on their environment.Baji Shaik is a database administrator and developer. He was introduced to databases in 2011 and over the years, has worked with Oracle, PostgreSQL, Postgres Advance Server, RedShift, and Greenplum. He has a wide range of expertise and experience in SQL/NoSQL databases such as Cassandra and DynamoDB. He is a database migration expert and has developed many successful database solutions addressing challenging business requirements for moving databases from on-premises to AWS Cloud using multiple AWS services. Baji has organized a number of PostgreSQL meet-ups and maintains his own technical blog, where he likes to share his knowledge with the community. He co-authored Beginning PostgreSQL on the Cloud, released in March 2018.CHAPTER 01. INSTALLING POSTGRESQL THE RIGHT WAY! (10 PAGES)There are multiple ways you can install PostgreSQL on a server. This chapter will talk about the best ways to do so, focusing on system-level parameter settings before installation as a prerequisite and also post-installation steps to avoid issues in the future.CHAPTER 02. CONFIGURING YOUR DATABASE FOR PERFORMANCE (20 PAGES)PostgreSQL ships with a basic configuration tuned for wide compatibility rather than performance. Although the default settings of PostgreSQL are viable, it is always recommended to tune some basic parameters based on your environment and application behavior.CHAPTER 03. ENABLE LOGGING OF YOUR DATABASE (15 PAGES)Logging is key when you troubleshoot issues of PostgreSQL for security and performance to find out the trends. Default PostgreSQL configuration comes with very minimal logging and it is not always enough to troubleshoot the issues. So, this chapter will explain how to set logging and consequences of high logging and how to deal with it.CHAPTER 04. MONITORING POSTGRESQL INSTANCES (15 PAGES)Good monitoring is a symbol of a peaceful life for an administrator. If you set up monitoring of your databases to alert you whenever an issue comes up, then you need not worry about keeping an eye at your databases' health. This chapter will show you ways to monitor PostgreSQL instances.CHAPTER 05. EXECUTE MAINTENANCE (15 PAGES)Why do you need maintenance? What would you get from it? when do decide "it's time for maintenance"? How do you do it? Is there any way I can improve my maintenance time? This chapter will shed some light on all these questions.CHAPTER 06. SECURING DATABASES (15 PAGES)Security is one of the major concerns for storing sensitive data. It could be one of the reasons customers change their database engines. So, this chapter will talk about how best you can secure your data in PostgreSQL.CHAPTER 07. BACKUP AND RESTORE BEST PRACTICES (15 PAGES)For critical data systems, backup and restore is a very important consideration. However, it's very important to know what factors you should consider before you implement a backup strategy and how to implement one. This chapter talks about developing backup procedures for critical/non-critical data systems and quick restore procedures as well.CHAPTER 08. HIGH AVAILABILITY PROCEDURES (15 PAGES)You may come across some situations where you cannot make your primary working with-in your affordable time window. What do you do in that scenario? Implementing High Availability is always the best practice for such critical applications. This chapter talks about HA implementation and open source tools that can be used with PostgreSQL to implement the same.CHAPTER 09. IMPLEMENTING POOLER (15 PAGES)While running your application with limited resources, then it is highly recommended to use Pooling to connect the database. Performance of a database depends on the parallel connections that it can allow. Huge connections to a database in parallel degrades the database performance. This chapter will teach you to implement a pooler mechanism for your PostgreSQL instances.CHAPTER 10. BASIC ERRORS AND HANDY QUERIES (15 PAGES)Working with PostgreSQL, there are bound to be some errors you might face that takes a lot of time to resolve. And, some times you might need some queries which are based on catalogs to fetch the information. This chapter talks about some of these errors and their resolution so that it can save some time for administrators followed by handy queries to help them perform their daily duties.

Living with Computers
The computing technology on which we are now so dependent has risen to its position of ascendency so rapidly that few of us have had the opportunity to take a step back and wonder where we are headed. This book urges us to do so.Taking a big-picture perspective on digital technology, Living with Computers leads the reader on a whistle-stop tour of the history of information and information technology. This journey culminates in a deep exploration into the meaning and role of computers in our lives, and what this experience might possibly mean for the future of human society – and the very existence of humanity itself.In the face of the transformative power of computing, this book provokes us to ask big questions. If computers become integrated into our bodies, merging with the information processing of our very DNA, will computing help to shape the evolution of biological life? If artificial intelligence advances beyond the abilities of the human brain, will this overturn our anthropocentrism and lead to a new view of reality? Will we control the computers of the future, or will they control us?These questions can be discomforting, yet they cannot be ignored. This book argues that it is time to reshape our definition of our species in the context of our interaction with computing. For although such science-fiction scenarios are not likely to happen any time soon – and may, in fact, never happen – it is nevertheless vital to consider these issues now if we wish to have any influence over whatever is to come. So, humans, let’s confront our possible destiny!JAMES W. CORTADA is a Senior Research Fellow at the Charles Babbage Institute at the University of Minnesota.

Driving Networked Service Productivity
Christofer F. Daiberl explores how to enhance the productivity of services delivered by a network of co-providers. Harnessing empirical insights and synthesizing contributions from service design, information systems, and engineering, the author develops a systematic productivity improvement technique. The technique supports practitioners to iteratively discover and seize opportunities to enhance productivity for their own organization, customers, and relevant co-providers. Reflecting on the overall results, five general design principles are proposed that support the development of new artifacts fostering truly productive services in a networked world. Christofer F. Daiberl received his PhD from the Friedrich-Alexander-Universität Erlangen-Nürnberg, where he worked as a Research Associate for Prof. Dr. Kathrin M. Möslein at the Chair of Information Systems – Innovation & Value Creation.
