...Research of Objective-C October 9, 2012 Introduction There is little doubt in today’s dynamic and fast moving technology market that Objective-C is a powerful, high-level, flexible programming language that has been around since the early 1980s and has the staying power to last a long time. Objective-C is an extension of the programming language C developed by Brad Cox and Tom Love to support the object oriented features of Smalltalk another programming language. Objective-C is the main language from which Apple’s MAC OS X for Desktops and laptops and iOS for iPhones and iPads are derived. There have been variants to this language as well, Objective-C++ and Objective-C 2.0 which proves the sustainability of this language. Due its portability, Objective-C has shown its flexibility and the ability to adapt to the ever changing and fast moving arena of mobile devices especially from Apple. What is Objective-C? Objective-C is a reflective programming language which aims to provide object orientated concepts and Smalltalk messaging to C. GNU Compiler Collection (GCC) provides a compiler for Objective-C, however due to the rich library support on OpenStep based operating systems (Mac OS X, IPhone, GNUstep) it is typically only used on these platforms. Objective-C is implemented as an augmentation to the C language. It is a superset of C which means that any Objective-C compiler can also compile C. To illustrate what Objective-C looks like as a language I will show you...

...The importance of being Earnest Values and attitudes of 1895 – The aristocratic Victorians valued duty and respectability above all else • Earnestness — a determined and serious desire to do the correct thing — was at the top of the code of conduct. Appearance was everything, and style was much more important than substance. So, while a person could lead a secret life, carry on affairs within marriage or have children outside of wedlock, society would look the other way as long as the appearance of propriety was maintained. For this reason, Wilde questions whether the more important or serious issues of the day are overlooked in favor of trivial concerns about appearance. Gwendolen is the paragon of this value. Her marriage proposal must be performed correctly, and her brother even practices correct proposals. Gwendolen's aristocratic attitude is "In matters of grave importance, style, not sincerity is the vital thing." The trivial is important; the serious is overlooked. • The tea ceremony in Act II is a hilarious example of Wilde's contention that manners and appearance are everything. The guise of correctness is the framework for war. Both women, thinking they are engaged to the same person, wage a civilized "war" over the tea service while the servants silently watch. When Gwendolen requests no sugar, Cecily adds four lumps to her cup. Although she asks for bread and butter, Gwendolen is given a large slice of cake. Her true feelings come out only in an aside that Cecily...

...1.0. INTRODUCTION A contract is a voluntary arrangement between two or more parties that is enforceable at law as a binding legal agreement. Contract have a history that where or when established. Contract law is based on the principle expressed in the Latin phrase “pacta sunt servanda”, (“agreements must be kept"). The common law of contract originated with the now-defunct writ of assumpsit, which was originally a tort action based on reliance. Contract law falls within the general law of obligations, along with tort, unjust enrichment, and restitution. Jurisdictions vary in their principles of freedom of contract. In common law jurisdictions such as England and the United States, a high degree of freedom is the norm. For example, in American law, it was determined in the 1901 case of Hurley v. Eddingfield that a physician was permitted to deny treatment to a patient despite the lack of other available medical assistance and the patient's subsequent death. This is in contrast to the civil law, which typically applies certain overarching principles to disputes arising out of contract, as in the French Civil Code. Other legal systems such as Islamic law, socialist legal systems, and customary law have their own variations. In contemporary times, each case requires an agreement between each other. It is intended that the contract is important in an agreement to prove that the two sides can conduct issues in a more prudent and responsible. Contract means the law that regulates...
