This chapter will teach you the basic elements of OpenCV and will show you how to accomplish the most fundamental tasks: reading, displaying, and saving images. Before you can start with OpenCV, you need to install the library. This is a simple process that is explained in the first recipe of this chapter. You also need a good development environment (IDE) to run your OpenCV applications. We pr…
Data-driven, or dynamic, programming is a series of techniques for modifying an application at runtime. You can accomplish this by storing screen definitions, business rules, and source code in a data source and then restoring them at runtime to alter the functionality of an application. The technology to perform data-driven programming encompasses many areas of software development. Language- …
This book is an updated and expanded version of Ruby in a Nutshell (O’Reilly) by Yukihiro Matsumoto, who is better known as Matz. It is loosely modeled after the classic The C Programming Language (Prentice Hall) by Brian Kernighan and Dennis Ritchie, and aims to document the Ruby language comprehensively but without the formality of a language specification. It is written for experienced pro…
AWS is not easy; it combines skills of several different (established) crafts. It is different from traditional systems administration, and it’s not just developing a piece of software. If you have practiced one or both of these skills, all you need is to be inquisitive and open to learning. Our background is in software engineering. We are computer scientists with extensive software engineer…
It’s ten o’clock on Monday morning. The boss of the branch office is in a rage. He’s been waiting for hours for an important e-mail, and it still hasn’t arrived. It can only be the fault of the mail server; it’s probably hung yet again. But a quick check of the computer shows that no mails have got stuck in the queue there,and there’snomentioneitherinthelogfilethatamailfromthesend…

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…
Internet advertising is a multi-billion-dollar industry, as is evident from the phenomenal success of companies like Google, Yahoo, Microsoft, and continues to grow at a rapid rate. With broadband access becoming ubiquitous, Internet traffic continues to grow in both volume and diversity, providing a rich supply of inventory to be monetized. Fortunately, the surge in supply has been accompanie…
When I first became interested in research into one particular form of African oral literature in 1961, I found to my surprise that there was no easily accessible work to which I could turn to give me some idea of what was known in this field, the various publications available, or the controversies and problems that demanded further investigation. In fact, I gradually discovered, there was an …

In response to a request from Congress, the Institute of Medicine (IOM) convened a committee to conduct an analysis of the federal government’s quality enhancement processes in six government programs—Medicare, Medicaid, the State Children’s Health Insurance Program, the Department of Defense TRICARE and TRICARE for Life programs, the Veterans Health Administration program, and the Indian…
This chapter reports on longitudinal research which explores the experience of mentally ill, developing artists. Through a particular use of the interview space and biographic narrative interviews, an intimate portrait was drawn of the different lines of continua these artistic individuals were negotiating. Such lines were traced through their „wellnesses,‟ their crises, their creative and …
The present decade has seen a blossoming of software tools, research pro- jects, and everyday practice that can loosely be characterized under the heading of ‘online deliberation’. A community has formed around this con- cept, and has met in international conferences, workshops, and special in- terest group sessions. The present volume, which grew out of the Second Conference on Online Deli…
Logical complexity of software systems is one of the main factors causing problems and errors in their planning, design, development, testing, deployment, maintenance, and use. There is a common under- standing that building complex software systems requires careful planning, good architectural design, and well-controlled development processes. Many good books and papers, as well as all softwar…
Window functions, to me, are the most profound feature supported by both standard SQL and Microsoft SQL Server’s dialect—T-SQL. They allow you to perform calculations against sets of rows in a flexible, clear, and efficient manner. The design of window functions is ingenious, overcoming a number of shortcomings of the traditional alternatives. The range of problems that window functions hel…
Ask any business, large or small, to identify one of its most important assets and it is bound to identify its confidential and proprietary information or ‘trade secrets’. This is because it is in the nature of businesses to try to secure a competitive advantage over rivals and inventing the proverbial ‘better mouse- trap’ is one way to do so. Frequently, businesses that invent or crea…
This third edition of the ICAO Safety Management Manual (SMM) (Doc 9859) supersedes the second edition, published in 2009, in its entirety. It also supersedes the ICAO Accident Prevention Manual (Doc 9422), which is obsolete. 1.1.2 This manual is intended to provide States with guidance on the development and implementation of a State safety programme (SSP), in accordance with the Internatio…
Enterprises, governments and societies at large have a new important agenda: tackling environmental issues and adopting environmentally sound practices. Over the years, information technology (IT) has fundamentally altered our work and life and improved our productivity, economy and social well-being. IT now has a new role to play – helping to create a greener, more sustainable environment wh…
In this essay, we investigate the dominant position of economics within the network of the social sciences in the United States. We begin by documenting the relative insularity of economics, using bibliometric data. Next we analyze the tight management of the field from the top down, which gives economics its characteristic hierarchical structure. Economists also distinguish themselves from…
