Short intro

What is Literate Programming?

Let us change our traditional attitude to the construction of programs: Instead of imagining that our main task is to instruct a computer what to do, let us concentrate rather on explaining to human beings what we want a computer to do.

The practitioner of literate programming can be regarded as an essayist, whose main concern is with exposition and excellence of style. Such an author, with thesaurus in hand, chooses the names of variables carefully and explains what each variable means. He or she strives for a program that is comprehensible because its concepts have been introduced in an order that is best for human understanding, using a mixture of formal and informal methods that reinforce each other.

– Donald Knuth


What is programming challenge?

Believe it or not, any course in computer programming covers all the tools strictly necessary to solve any problem that can be solved with a computer. A very famous computer scientist named Alan Turing conjectured, and it is now widely accepted, that any problem solvable with computers requires only the basic statements that all computer programming languages include: decision statements (e.g. , if), looping statements (e.g. , for and while) and the ability to store and retrieve data. Since you already know about these, you may wonder what else there is to learn. That's a good question.

If you think of computer programming as a process similar to constructing a building, right now you have the knowledge equivalent to how to use a few tools such as a hammer, screwdriver, saw, and drill. Those might be all the tools necessary to build a house, but that does not mean you can build yourself a habitable home, let alone one that meets modern building codes. That's not to say that you can't do some useful things. You are probably capable of building benches or birdhouses, you're just not yet ready for the challenges that come with a larger project. In programming, just as in house construction, tackling bigger projects requires additional knowledge, techniques, and skills.
