With ten years of learning to program, a good article
Called the Yourself Programming in Ten Years

Why is everyone hungry?

Walk into any bookstore, you will see "called Yourself Java in 7 Days" next to the Java self-taught (7 Days) is at the end of a long row to see

Of similar books, they will teach you to Visual Basic, Windows, Internet, etc., and only need a few days or even a few hours, I search on Amazon.com for the following: for its pubdate: after 1992 and the title: days and (title: learn the or title: called yourself), and publication date: 1992 title: day and (title: to learn the or title: self-taught))
I got 248 search results, a total of 78 is in front of the computer books (79th is "Learn Bengali in 30 days", 30 days to Learn Bengali), I change the keyword "days" to "pump", very similar results were obtained: the 253 book, the first 77 computer books, 78 was called the "Yourself Grammar and Style in 24 hours" to Learn Grammar and Style (24 hours), the first 200 book, 96% were computer books,
The conclusion is that either people are very eager to learn the computer, or don't know why computer surprisingly simple, is easier to learn than anything, no book is to teach people appreciate in a few days Beethoven, or quantum physics, or even how to dog grooming,
Let's analyze like "Learn Pascal in Three Days." "Learn to Pascal (3 Days), what exactly is this topic:
Society: in 3 days, you not enough time to write some meaningful programs, and learn from their failures and successes, you have not enough time to work with some experienced programmers, you never know what it is like in that environment, in short, don't have enough time to let you learn a lot, so these books talk about only on the surface of a master, rather than a thorough understanding of, such as Alexander Pope, British poet, writer, 1688-1744), a little learning is a dangerous thing (a little learning is a dangerous thing)

Pascal: in 3 days you can learn to Pascal syntax category (if you have a similar language), but you can't learn how to use the grammar, in short, if you are, for example a Basic programmer, you can learn to write Basic style in Pascal syntax, but you won't learn Pascal real advantages (and disadvantages), where the key? Alan Perlis (ACM's first President, Turing award winner, 1922-1990) once said: "if a language does not influence your thoughts on programming, it is not worth to learn", another view is that sometimes you have to learn some Pascal (more likely to be Visual Basic and javascript and so on) of the fur, because you need to contact the existing tools, used to accomplish a specific task, but at the moment, you're not learning how to program, you are learning how to complete the task, day 3: unfortunately, this is not enough, is the following section,
