This PhoneGap 4 cookbook is a practical guide to developing hybrid applications using PhoneGap or Cordova. The sample applications here are based on real-world use cases and are shown step by step. This book covers the standard workflow using the Cordova command-line interface, and the extension of hybrid applications using various Cordova plugins. It also covers the development of hybrid appl…
When Olaf Kirche joined the LDP in 1992, he wrote two small chapters on UUCP and smail, which he meant to contribute to the System Administrator’s Guide. Development of TCP/IP networking was just beginning, and when those “small chapters” started to grow, he wondered aloud whether it would be nice to have a Networking Guide. “Great!” everyone said. “Go for it!” So he went for it a…
To be able to define IoT, let's first look at how the term was coined. Kevin Ashton noted that most data on the Internet was at the time originally entered or captured into the system by human beings. From a system point of view, a human is nothing more than a slow, error-prone, and inefficient router of data that puts limits on quality and quantity of data available and sometimes even dares to…
Firewalls are a staple of almost every network in the world. The firewall protects nearly every network-based transaction that occurs, and even the end user understands its metaphoric name, meant to imply keeping out the bad stuff. But firewalls have had to change. Whether it’s the growth of networks or the growth of network usage, they have had to move beyond the simple devices that only req…
After you’ve spent some time in the networking field, you tend to notice that there is rarely a single way to do things, and in many cases, rarely a single, precise definition for terms. After all, often a network engineer’s best answer is “it depends.” Such is the case with enterprise routing, so let’s start off with a definition question: what is an enterprise network? Is it a large…
This book describes the jobs that I and other networking engineers have performed on client networks over the past few years. We are considered network warriors because of the way that we attack networking challenges and solve issues for our clients. Network warriors come from different backgrounds, including service provider routing, security, and the enterprise. They are experts on many diffe…
Albert Gelpi’s American Poetry after Modernism is a study of major poets of the postwar period from Robert Lowell and Adrienne Rich through the Language poets. He argues that what distinguishes American poetry from the British tradition is, paradoxically, the lack of a tradition; as a result, each poet has to ask fundamental questions about the role of the poet and the nature of the medium, h…
GNU-Linux is the ultimate hacker’s playground. It’s a toy for the imagination, not unlike a box of blocks or a bag of clay. Whether someone is an artist or a scientist, the possibilities are endless. Anything that you want to try to do and build and make with a computer is subject only to your creativity. This is why so many people are interested in Linux. Many call it Linux instead of GNU-…
In this book, we'll build several projects that will get progressively more challenging. You should be able to build the first few projects in an afternoon. A finished product may take you a while longer, depending on how professional you want it to look. In order to build the first few projects in this book, you will need a few basic assembly skills and tools described as follows. The RF proje…
T he information security (InfoSec) profession got its start decades ago, but it consisted of few people, mostly in military and other secret orga- nizations. With the appearance of the Internet in the 1990s, organizations started to put information online, and the InfoSec profession became a little more popular. Fast‐forward to the mid 2010s, with its big security breaches as well as new law…

n times of crisis, we are forcefully reminded of the links between politics and international economic law.1 Indeed, the meltdown in world markets has refocused attention on how the fingerprints of the “visible hand” can be seen all over the institutions that underpin the rules of globalization. From trade and investment to finance, governments are under pressure to enforce, resist, and rew…
Software that drives the operations of sensors and communication among sensors is basic to any meaningful application of sensor networks. The goal of this book is to provide an understanding of how this software functions; how it allows the sensors to gather information, process it, and interact with each other in networks; and how these networks interact with the physical world. One aim of thi…
Why Mac at Work? Because everyone needs an advantage. A few years ago, I spoke at the American Bar Association’s technology conference about how I use my Mac to run circles around other lawyers. This conference happens once a year and is ground zero for cutting-edge legal technology. When I started talking to these Mac lawyers, however, their ugly secret was revealed: although they were usi…
To secure an Oracle database, you must modify your mindset to think about securing the data and not about securing the software. To secure the software is literally impossible, because the software is almost infinitely configurable and the software does not know anything about your system (apart from what you www.it-ebooks.info CHAPTER 15 ■ SECURING DATA 532 tell it), your applicatio…
Application security is on the forefront of everyone’s minds these days. It’s almost impossible to go more than a couple of days without reading about another website organization that was hacked or had a data breach. Unfortunately, it seems as if the problem is getting worse with time, not better. This can be attributed directly to the fact that there are simply more people using computers…
Ethernet switches, also known as bridges, are basic building blocks of networks, and are so commonly used that you may not give them a second thought. It’s possible to build networks without knowing very much about how switches work. However, when you build larger network systems, it helps to understand both what goes on inside a switch and how the standards make it possible for switches to w…
