Introduction to Objects “We cut nature up, organize it into concepts, and ascribe significances as we do, largely because we are parties to an agreement that holds throughout our speech community and is codified in the patterns of our language … we cannot talk at all except by subscribing to the organization and classification of data which the agreement decrees.” Benjamin Lee Whorf (1897-1941) The genesis of the computer revolution was in a machine. The genesis of our programming languages thus tends to look like that machine. But computers are not so much machines as they are mind amplification tools (“bicycles for the mind,” as Steve Jobs is fond of saying) and a different kind of expressive medium. As a result, the tools are beginning to look less like machines and more like parts of our minds, and also like other forms of expression such as writing, painting, sculpture, animation, and filmmaking. Object-oriented programming (OOP) is part of this movement toward using the computer as an expressive medium. This chapter will introduce you to the basic concepts of OOP, including an overview of development methods. This chapter, and this book, assumes that you have some programming experience, although not necessarily in C. If you think you need more preparation in programming before tackling this book, you should work through the Thinking in C multimedia seminar, downloadable from www.MindView.net.
This chapter is background and supplementary material. Many people do not feel comfortable wading into object-oriented programming without understanding the big picture first. Thus, there are many concepts that are introduced here to give you a solid overview of OOP. However, other people may not get the big picture concepts until they’ve seen some of the mechanics first; these people may become bogged down and lost without some code to get their hands...

Best Thing Ever

...sfsBLUE AND RED HERP DERP Oops … she did it again! Britney Spears has found herself smack dab in the middle of another controversy pertaining to her photo spread in the December issue of Lucky, which hit the web on Friday. "The X Factor" judge dons several different relatively conservative outfits in the mag and reveals some of her fashion secrets — for example, she hates socks. While the whole thing seems pretty innocuous, there's been a big backlash from her fans, who are complaining that the entertainer seems to be wearing a bad wig in pictures that appear to be heavily retouched. [Related: Stars Without Photoshop] In the photos, the 30-year-old singer's hairline does look lower than usual and her part is in a different spot. The texture of her locks also seems different — it's much fuller and more unnatural looking than what we see when she's seated at the judges' table, prompting rumors that she's wearing a wig or some type of a weave. One fan even tweeted at the mag, "Did @britneyspears even show up for the photoshoot or did you just photoshop her face on a body[?]" To us, Spears' tresses scream Kim Zolciak — and we all know that "The Real Housewives of Atlanta" star is all about the wigs. [Related: Kim Zolciak Wigs Out] In the Lucky interview, Spears also talks about her issues dealing with acne, but you can't see a single mark on her face in the pics. While magazines are known for retouching, fans found this to be an "extreme" example with some saying she looks...

Me, Me Me

...In January 2008 a British journalist, Sarfraz Manzoor, wrote an article with the title “Me, Me, Me” that appeared in the magazine “Esquire”. He gives his opinion on how the phenomenon “New Narcissism” has its influences on today’s society through the Internet. And he leaves us with the impression that there is a reason to be worried about today's youth being more narcissistic than ever before. Narcissism is not new for us. New Narcissism is a modern version of the phenomenon narcissism. And it has been known since ancient Greece with the Greek myth about Narcissus that fell in love with his own reflection in the water. The man that got narcissism recognized as a medical condition was Sigmund Freud (l. 53). But in our age, the word, narcissism, does not seem that serious and is mostly defined as a phenomenon. This New Narcissism has come to life because society reproduces itself (l. 59). And growing numbers of people are more narcissistic according to a study performed by psychologists. Sarfraz Manzoor, who has written this article, describes that New Narcissism is the offspring of today’s society. He makes an example by including a person named Chris Crocker. Crocker became famous because he put a video on the Internet where he defended the celebrity Britney Spears. There can be two reasons for his behaviour. Is he doing this to tell people that they shall back off and because he is fond of her? Or is he doing this to get attention? But it does not seem as if Britney is......
