A day in my life without TV is like a day without sunshine. But a day in my life without 3D TV is like, well no big deal. If you were going to make a pact to watch at least one new 3D TV DVD or TV show per day starting with the first of the new year, you’d be done watching before February was over.

There is just not that much 3D TV content out in the vendors racks to justify almost 1000 more for the 3D version of my 50 inch 2D TV. And just throwing in a free copy of that Avatar thing is not a big help in making the deal worthwhile. A 500 rebate or a half price Blu-ray DVD player to play the as of yet non-existent 3D TV DVD collection on, then maybe you could turn my head just a bit.

Not that there is anything wrong with 3D TV as the technology has come a long way from the cardboard glasses days. But unless you have money to burn or just want to have the newest gadget, 3D TV is a hard nut to crack. The industry is going to have to wait out the content producers for sales to take off, and hope the content producers aren’t waiting for 3D TV sales to take off as it could become a Mexican standoff at best.

What is programming
As this course is titled “Introduction to programming”, therefore it is most essential and appropriate to understand what programming really means. Let us first see a widely known definition of programming.
Definition: “A program is a precise sequence of steps to solve a particular problem.”
It means that when we say that we have a program, it actually means that we know about a complete set activities to be performed in a particular order. The purpose of these activities is to solve a given problem.
Alan Perlis, a professor at Yale University, says:
“It goes against the grain of modern education to teach children to program. What fun is there in making plans, acquiring discipline in organizing thoughts, devoting attention to detail and learning to be self-critical? “
It is a sarcastic statement about modern education, and it means that the modern education is not developing critical skills like planning, organizing and paying attention to detail. Practically, in our day to day lives we are constantly planning, organizing and paying attention to fine details (if we want our plans to succeed). And it is also fun to do these activities. For example, for a picnic trip we plan where to go, what to wear, what to take for lunch, organize travel details and have a good time while doing so.
When we talk about computer programming then as Mr. Steve Summit puts it
“At its most basic level, programming a computer simply means telling it what to do, and this vapid-sounding definition is not even a joke. There are no other truly fundamental aspects of computer programming; everything else we talk about will simply be the details of a particular, usually artificial, mechanism for telling a computer what to do. Sometimes these mechanisms are chosen because they have been found to be convenient for programmers (people) to use; other times they have been chosen because they’re easy for the computer to understand. The first hard thing about programming is to learn, become comfortable with, and accept these artificial mechanisms, whether they make “sense” to you or not. “

Why Programming is important
The question most of the people ask is why should we learn to program when there are so many application software and code generators available to do the task for us. Well the answer is as give by the Matthias Felleisen in the book How to design programs’
“The answer consists of two parts. First, it is indeed true that traditional forms of programming are useful for just a few people. But, programming as we the authors understand it is useful for everyone: the administrative secretary who uses spreadsheets as well as the high-tech programmer. In other words, we have a broader notion of programming in mind than the traditional one. We explain our notion in a moment. Second, we teach our idea of programming with a technology that is based on the principle of minimal intrusion. Hence, our notion of programming teaches problem-analysis and problem-solving skills without imposing the overhead of traditional programming notations and tools.”
Hence learning to program is important because it develops analytical and problem solving abilities. It is a creative activity and provides us a mean to express abstract ideas. Thus programming is fun and is much more than a vocational skill. By designing programs, we learn many skills that are important for all professions. These skills can be summarized as:
o Critical reading
o Analytical thinking
o Creative synthesis
What skills are needed
Programming is an important activity as people life and living depends on the programs one make. Hence while programming one should
o Paying attention to detail
o Think about the reusability.
o Think about user interface
o Understand the fact the computers are stupid
o Comment the code liberally
Paying attention to detail
In programming, the details matter. This is a very important skill. A good programmer always analyzes the problem statement very carefully and in detail. You should pay attention to all the aspects of the problem. You can’t be vague. You can’t describe your program 3/4th of the way, then say, “You know what I mean?”, and have the compiler figure out the rest.
Furthermore you should pay attention to the calculations involved in the program, its flow, and most importantly, the logic of the program. Sometimes, a grammatically correct sentence does not make any sense. For example, here is a verse from poem “Through the Looking Glass” written by Lewis Carol:

CS201 Introduction to Programming
“Twas brillig, and the slithy toves
Did gyre and gimble in the wabe “
The grammar is correct but there is no meaning. Similarly, the sentence, “Mr. ABC sleeps thirty hours every day”, is grammatically correct but it is illogical.
So it may happen that a program is grammatically correct. It compiles and runs but produces incorrect or absurd results and does not solve the problem. It is very important to pay attention to the logic of the program.
Think about the reusability
When ever you are writing a program, always keep in mind that it could be reused at some other time. Also, try to write in a way that it can be used to solve some other related problem. A classic example of this is:
Suppose we have to calculate the area of a given circle. We know the area of a circle is (Pi * r2). Now we have written a program which calculates the area of a circle with given radius. At some later time we are given a problem to find out the area of a ring. The area of the ring can be calculated by subtracting the area of outer circle from the area of the inner circle. Hence we can use the program that calculates the area of a circle to calculate the area of the ring.
Think about Good user interface
As programmers, we assume that computer users know a lot of things, this is a big mistake. So never assume that the user of your program is computer literate. Always provide an easy to understand and easy to use interface that is self explanatory.

CS201 Introduction to Programming
Understand the fact that computers are stupid
Computers are incredibly stupid. They do exactly what you tell them to do: no more, no less– unlike human beings. Computers can’t think by themselves. In this sense, they differ from human beings. For example, if someone asks you, “What is the time?”, “Time please?” or just, “Time?” you understand anyway that he is asking the time but computer is different. Instructions to the computer should be explicitly stated. Computer will tell you the time only if you ask it in the way you have programmed it.
When you’re programming, it helps to be able to “think” as stupidly as the computer does, so that you are in the right frame of mind for specifying everything in minute detail, and not assuming that the right thing will happen by itself.
Comment the code liberally
Always comment the code liberally. The comment statements do not affect the performance of the program as these are ignored by the compiler and do not take any memory in the computer. Comments are used to explain the functioning of the programs. It helps the other programmers as well as the creator of the program to understand the code.
Program design recipe
In order to design a program effectively and properly we must have a recipe to follow. In the book name How to design programs’ by Matthias Felleisen.and the co-worker, the idea of design recipe has been stated very elegenlty as
“Learning to design programs is like learning to play soccer. A player must learn to trap a ball, to dribble with a ball, to pass, and to shoot a ball. Once the player knows those basic skills, the next goals are to learn to play a position, to play certain strategies, to choose among feasible strategies, and, on occasion, to create variations of a strategy because none fits. “
The author then continue to say that:
“A programmer is also very much like an architect, a composers, or a writer. They are creative people who start with ideas in their heads and blank pieces of paper. They conceive of an idea, form a mental outline, and refine it on paper until their writings reflect their mental image as much as possible. As they bring their ideas to paper, they employ basic drawing, writing, and playing music to express certain style elements of a building, to describe a person’s character, or to formulate portions of a melody. They can practice their trade because they have honed their basic skills for a long time and can use them on an instinctive level.
Programmers also form outlines, translate them into first designs, and iteratively refine them until they truly match the initial idea. Indeed, the best programmers edit and rewrite their programs many times until they meet certain aesthetic standards. And just like soccer players, architects, composers, or writers, programmers must practice the basic skills of their trade for a long time before they can be truly creative.
Design recipes are the equivalent of soccer ball handling techniques, writing techniques, arrangements, and drawing skills. “
