A Beginner's Guide to Scala, Object Orientation and Functional Programming
by John HuntScala is now an established programming language developed by Martin Oderskey and his team at the EPFL. The name Scala is derived from Sca(lable) La(nguage). Scala is a multi-paradigm language, incorporating object oriented approaches with functional programming. Although some familiarity with standard computing concepts is assumed (such as the idea of compiling a program and executing this compiled from etc.) and with basic procedural language concepts (such as variables and allocation of values to these variables) the early chapters of the book do not assume any familiarity with object orientation nor with functional programming These chapters also step through other concepts with which the reader may not be familiar (such as list processing). From this background, the book provides a practical introduction to both object and functional approaches using Scala. These concepts are introduced through practical experience taking the reader beyond the level of the language syntax to the philosophy and practice of object oriented development and functional programming. Students and those actively involved in the software industry will find this comprehensive introduction to Scala invaluable.

Scala is a multi-paradigm language, incorporating object oriented approaches with functional programming. Although some familiarity with standard computing concepts is assumed (such as the idea of compiling a program and executing this compiled form, etc.) and with basic procedural language concepts (such as variables and allocation of values to variables) the early chapters of the book do not assume any familiarity with object orientation nor functional programming. These chapters also step through other concepts with which the reader may not be familiar (such as list processing). From this background, John Hunt provides a practical introduction to object and functional technology using Scala, one of the newest and most interesting programming languages available. A variety of concepts are introduced through practical experience taking the reader beyond the level of the language syntax to the philosophy and practice of object-oriented development and functional programming. Students, and those actively involved in the software industry will find this comprehensive introduction to Scala and to object orientation and functional programming, invaluable.
Scala Design Patterns
by John HuntScala is a new and exciting programming language that is a hybrid between object oriented languages such as Java and functional languages such as Haskell. As such it has its own programming idioms and development styles. Scala Design Patterns looks at how code reuse can be successfully achieved in Scala. A major aspect of this is the reinterpretation of the original Gang of Four design patterns in terms of Scala and its language structures (that is the use of Traits, Classes, Objects and Functions). It includes an exploration of functional design patterns and considers how these can be interpreted in Scala's uniquely hybrid style. A key aspect of the book is the many code examples that accompany each design pattern, allowing the reader to understand not just the design pattern but also to explore powerful and flexible Scala language features. Including numerous source code examples, this book will be of value to professionals and practitioners working in the field of software engineering.

Windows NT TCP/IP Network Administration
by Craig Hunt Robert Bruce ThompsonWindows NT TCP/IP Network Administration is a complete guide to setting up and running a TCP/IP network on Windows NT. It starts with the fundamentals-- the protocols, routing, and setup. Beyond that, it covers all the important networking services provided as part of Windows NT, including IIS, RRAS, DNS, WINS, and DHCP. This book is the NT administrator's indispensable guide.
Windows Server 2003 Network Administration: Building and Maintaining Problem-Free Windows Networks
by Craig Hunt Roberta BraggThis book is the Windows Server version of the classic TCP/IP Network Administration. Like the book that inspired it, Windows Server 2003 Network Administration provides an overview of the essential TCP/IP protocols, and explains how to properly manage and configure the services based on these protocols. Any skilled network administrator knows that understanding how things work is as important as knowing how things are done. This book is the essential guide to both, containing everything a network administrator needs to exchange information via the Internet, and to build effective reliable networks. This must-read guide is divided into three distinct sections: fundamental concepts, tutorial, and reference. The first three chapters are a basic discussion of the network protocols and services. This discussion provides the fundamental concepts necessary to understand the rest of the book. The remaining chapters provide a how-to tutorial for planning, installing and configuring various important network services. The book concludes with three appendixes that are technical references for various configuration options. Content specifics include how to: Install, configure, and manage a Microsoft DNS and Windows DHCP server Control remote communications with Microsoft RRAS software Protect hosts with Internet Connection Firewalls Configure Internet and Intranet Web services with IIS Design proper security into your network Troubleshoot the network when problems develop After you've turned the final page of Windows Server 2003 Network Administration, you'll not only understand how to network, but also why it needs to be done.
sendmail Cookbook
by Craig HuntMore often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology. Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem. Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances. The sendmail Cookbook begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:Delivering and forwarding mail Relaying Masquerading Routing mail Controlling spam Strong authentication Securing the mail transport Managing the queue Securing sendmailsendmail Cookbook is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the sendmail Cookbook and say good-bye to sendmail dread.
TCP/IP Network Administration
by Craig HuntThis complete guide to setting up and running a TCP/IP network is essential for network administrators, and invaluable for users of home systems that access the Internet. The book starts with the fundamentals -- what protocols do and how they work, how addresses and routing are used to move data through the network, how to set up your network connection -- and then covers, in detail, everything you need to know to exchange information via the Internet. Included are discussions on advanced routing protocols (RIPv2, OSPF, and BGP) and the gated software package that implements them, a tutorial on configuring important network services -- including DNS, Apache, sendmail, Samba, PPP, and DHCP -- as well as expanded chapters on troubleshooting and security. TCP/IP Network Administration is also a command and syntax reference for important packages such as gated, pppd, named, dhcpd, and sendmail. With coverage that includes Linux, Solaris, BSD, and System V TCP/IP implementations, the third edition contains: Overview of TCP/IP Delivering the data Network services Getting startedM Basic configuration Configuring the interface Configuring routing Configuring DNS Configuring network servers Configuring sendmail Configuring Apache Network security Troubleshooting Appendices include dip, ppd, and chat reference, a gated reference, a dhcpd reference, and a sendmail reference This new edition includes ways of configuring Samba to provide file and print sharing on networks that integrate Unix and Windows, and a new chapter is dedicated to the important task of configuring the Apache web server. Coverage of network security now includes details on OpenSSH, stunnel, gpg, iptables, and the access control mechanism in xinetd. Plus, the book offers updated information about DNS, including details on BIND 8 and BIND 9, the role of classless IP addressing and network prefixes, and the changing role of registrars. Without a doubt, TCP/IP Network Administration, 3rd Edition is a must-have for all network administrators and anyone who deals with a network that transmits data over the Internet.

Professional Web Design (2nd Edition)
by Eric Hunley Erik Simmons Clint EccherThe current state of Web design is in a transitory phase. The latest push is for the use of "standards" set out by the World Wide Web Consortium (W3C). These standards were created so that different browsers will display Web pages in the same, or at least very similar manner. One of the most important elements to these standards has been the increased popularity and usage of Cascading Style Sheets (CSS). Cascading Style Sheets were created as a means to separate markup from presentation, which results in cleaner code. Because of the immense importance of CSS, the coverage in this book has been increased with a complete chapter dedicated to them. Ultimately, Web design is headed to using pure CSS for all presentation and layout of Web pages. However, at this point, the use of CSS is not quite ready to take over completely. Browsers do not have sufficient support, and the language is still growing. The only way that designers can be certain that a page looks as close as possible to what is intended is through the use of tables. That is the main focus of this edition. The first edition introduced the idea of mortising and the use of nested tables for layout. This edition continues with that, but adds more information about CSS, client-side scripting with JavaScript, and server-side scripting with PHP as sites are growing with the amount of content they are serving. This edition can be seen as a bridge to the future. It explores the traditional methods of table-based design, but introduces more CSS, which will ultimately take over.
Build a Binary Clock with Elixir and Nerves
by Frank Hunleth Bruce TateWant to get better at coding Elixir? Write a hardware project with Nerves. As you build this binary clock, you'll build in resiliency using OTP, the same libraries powering many commercial phone switches. You'll attack complexity the way the experts do, using a layered approach. You'll sharpen your debugging skills by taking small, easily verified steps toward your goal. When you're done, you'll have a working binary clock and a good appreciation of the work that goes into a hardware system. You'll also be able to apply that understanding to every new line of Elixir you write. Combining software with hardware can be frustrating, but you can become proficient in no time by taking a simple, logical approach. Blinking a single LED is the traditional "hello-world" of embedded systems. Building your own binary clock is the logical next step. It blinks groupings of LEDs based on the system time. This guide walks you through a working project using the techniques used by experts who build software for hardware every day. This common sense project moves forward in tiny, logical steps. As you progress, you can verify each step before moving on to the next. You don't have to be a Nerves novice to benefit from this project. Become a better Elixir programmer as you build your own desktop showpiece. With a layered approach to software design, you'll learn to control the complexity of your programs the way the experts do by focusing on one small slice of your system at a time. When you're done, you'll have your own binary clock, and also more of the tools you need to design and build your own Nerves and Elixir projects. You'll also be a better programmer with a deeper appreciation of layering techniques for controlling complexity. What You Need: This project is for Elixir developers who want to get started with Nerves, or improve their skills. The project is designed for Elixir 1.11 and Nerves 1.7, but later versions will probably work as well with slight modifications. The project uses a Raspberry Pi zero with a set of components. With slight modifications, you can make this book work with other components as well.
Creeping Failure: How We Broke the Internet and What We Can Do to Fix It
by Jeffrey HunkerThe Internet is often called a superhighway, but it may be more analogous to a city: an immense tangle of streets, highways, and interchanges, lined with homes and businesses, playgrounds and theatres. We may not physically live in this city, but most of us spend a lot of time there, and even pay rents and fees to hold property in it.But the Internet is not a city of the 21st century. Jeffrey Hunker, an internationally known expert in cyber-security and counter-terrorism policy, argues that the Internet of today is, in many ways, equivalent to the burgeoning cities of the early Industrial Revolution: teeming with energy but also with new and previously unimagined dangers, and lacking the technical and political infrastructures to deal with these problems. In a world where change of our own making has led to unexpected consequences, why have we failed, at our own peril, to address these consequences?Drawing on his experience as a top expert in information security, Hunker sets out to answer this critical question in Creeping Failure. Hunker takes a close look at the "creeping failures" that have kept us in a state of cyber insecurity: how and why they happened, and most crucially, how they can be fixed. And he arrives at some stunning conclusions about the dramatic measures that we will need to accomplish this.This groundbreaking book is an essential first step toward understanding the World Wide Web in a larger context as we try to build a safer Internet "city." But it also raises issues that are relevant far outside the online realm: for example, how can we work together to create not just new policy, but new kinds of policy? Creeping Failure calls for nothing less than a basic rethinking of the Internet -- and of how we solve problems together.From the Hardcover edition.
