This book has been created to serve the needs of many SAP Business One users. If you have a chance to browse the SAP business One website between mid-2008 and mid-2011, you will find that my name is always on the top contributor's list. I have solved many SQL Query related problems faced by many users, and some such users have asked me to write a blog or wiki page on the topic. However, the su…
“What an amazing job you have,” a developer recently told me during a break at a conference. “You seem so passionate about it. i wish i could be paid to do something i like, too.” Sadly, he was not the first one to tell me something like this, and he won’t be the last. How can great developers reach the next level and do what they like for a living? How come someone like me, an averag…
This is a practical book that will tell you everything you need to know to solve and create Sudoku puzzles in C. My intention is not to teach you how to become a software developer but rather how to use computer programs to deal with Sudokus. Therefore, you will not find here theoretical analyses of algorithms, solvability problems, or complexity theory. All the code I present and comment on in…
Swift, the new programming language that replaces Objective C, was announced by Apple on June 2, 2014. Since then, there have been many updates to the language. At the time of writing of this book, we are at version 2. Swift is a very well-structured programming language that takes many features from existing modern languages such as C#, Haskell, and Python, and it introduces a few new feature…
As its main theme, the book presents qualitative research from a practical perspective. Such a view reveals insights into how qualitative research is done, at the ground level. The approach should be especially useful if in fact you are actually wanting to conduct a qualitative study—whether it is to be self-standing, part of a larger study, or an academic or training assignment for an underg…
Every program’s user interface is crucial to letting users control a program. It doesn’t matter how powerful your program may be if the user interface frustrates users and discourages them from using the program. Since every user interface needs to respond to changes the user might make to the size of a window, stack views let you group related items together and apply constraints on that e…
Swift is an exciting new language from Apple, first announced at the Apple Worldwide Developers Conference (WWDC) in June 2014. The language started life as the brainchild of Chris Lattner, director of Apple’s Developer Tools Department, and is the next step in the evolution of Apple’s software development ecosystem. Swift brings with it many modern language features, including type safety,…
This chapter will introduce the BASIC-256 environment using the print and say statements. You will see the difference between commands you send to the computer, strings of text, and numbers that will be used by the program. We will also explore simple mathematics to show off just how talented your computer is. Lastly you will learn what a syntax-error is and how to fix them.
In 1849, at a time when classical liberalism was still the dominant ideological force and “economist” and “socialist” were generally considered antonyms, Gustave de Molinari, a renowned Belgian economist, wrote, If there is one well-established truth in political economy, it is this: That in all cases, of all commodities that serve to provide for the tangible or intangible need of the c…
This book is about Tcl, the scripting language developed by John Ousterhout. Tcl stands for tool command language and was originally designed as a simple scripting language interpreter that could be embedded inside applications written in the C language. With the addition of the Tk graphical toolkit and a host of other language extensions supporting such features as graphics, relational databas…
One of the simplest and natural types of information representation is by means of written texts. Data to be processed often does not decompose into independent records. This type of data is characterized by the fact that it can be written down as a long sequence of characters. Such linear sequence is called a text. The texts are central in "word processing" systems, which provide facilities fo…
Bowing to the physics of heat and power, processor clock speeds could not keep doubling every 18 months as they had been doing for the past three decades or more. In order to keep increasing the processing power of the next generation over the current generation, processor manufacturers began producing chips with multiple processor cores. More processors running at a reduced speed generate less…
From the beginning, one of the promises of the .NET Framework has been language interoperability; that is, developers targeting the platform could write code in one language and interact with code written in another language through the Common Language Infrastructure (CLI). Early examples often included a library written in C# utilizing a library written in Visual Basic, or vice versa. Ideally,…
The very first time was when I took a programming class during my freshman year of college. It was a mandatory course for the curriculum Ihad decided to enroll in. It wasn’t like what I had seen in so many movies during my child- hood. I didn’t type in a few simple commands, press ENTER, and watch a trash-can robot say “hello.” There wasn’t even a trash-can robot in this class. Inste…
This volume, Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation, is a Special Report of the Intergovernmental Panel on Climate Change (IPCC). The report is a collaborative effort of Working Group I (WGI) and Working Group II (WGII). The IPCC leadership team for this report also has responsibility for the IPCC Fifth Assessment Report (AR5), scheduled for c…

Since its early ARPANET inception during the Cold War, the Internet has grown by a staggering nine orders of magnitude. Today, the Internet and the World Wide Web pervade our lives, having fundamentally altered the way we seek, exchange, distribute, and process information. The Internet has become a powerful social force, transforming communication, entertainment, commerce, politics, medicine, …
The beauty and success of Twitter lies in its simplicity.It’s simple not just for its users but also within its rich application programming interface (API),which provides you the tools required to interact with Twitter’s internal services.The Twitter API is responsible for more than 90% of Twitter server traffic and provides the gateway to much of Twitter’s core functionality,such as sta…
This book is for anyone who has basic knowledge of web development and who wants to enhance their knowledge on mobile website performance optimization. By reading this book, a user will get to know how to measure their website's performance, the tools they can use to debug and monitor their website, and the tips and tricks to optimize their website.
Let’s get familiar with dRuby. dRuby stands for “distributed Ruby.” It’s one of the standard libraries that comes with the Ruby core code, and you can use it to write distributed programming apps without the hassle of installing and configuring additional components. In this chapter (because it’s an unwritten rule), we’ll start with “Hello, World” and then create a small reminde…
When learning a new language, there are three things that you need to understand. The first and most important is the abstract model that the language presents. The next is the concrete syntax. Finally, you need to learn your way around the standard libraries and the common idioms of the language. This chapter will look at the abstract model that Go presents to programmers. If you want to dive…
When this book was conceived, our first instinct was to create a comprehensive comparison between Clojure and its host language, Java. After further reflection, we reached the conclusion that such an approach would be disingenuous at best, and disastrous at worst. Granted, some points of comparison can’t be avoided, but Java is very different from Clojure and to try and distort one to explain…
In this book, I describe the Linux programming interface-the system calls, library functions, and other low-level interfaces are used, directly or indirectly, by every program that runs on Linux.
