I've never been a good estimator of how long things are going to take. Donald Knuth More Quotes by Donald Knuth More Quotes From Donald Knuth Computer programming is an art, because it applies accumulated knowledge to the world, because it requires skill and ingenuity, and especially because it produces objects of beauty. A programmer who subconsciously views himself as an artist will enjoy what he does and will do it better. Donald Knuth skillsviewsart Programming is the art of telling another human being what one wants the computer to do.

If you find that you're spending almost all your time on practice, start turning some attention to theoretical things; it will improve your practice.

I occasionally carry flash memory drives between this machine and the Macs that I use for network surfing and graphics; but I trust my family jewels only to Linux.

What I do takes long hours of studying and uninterruptible concentration. Donald Knuth roleslongpeople The best programs are written so that computing machines can perform them quickly and so that human beings can understand them clearly. A programmer is ideally an essayist who works with traditional aesthetic and literary forms as well as mathematical concepts, to communicate the way that an algorithm works and to convince a reader that the results will be correct. Donald Knuth algorithmsmachinesway The book Dynamic Programming by Richard Bellman is an important, pioneering work in which a group of problems is collected together at the end of some chapters under the heading "Exercises and Research Problems," with extremely trivial questions appearing in the midst of deep, unsolved problems. It is rumored that someone once asked Dr. Bellman how to tell the exercises apart from the research problems, and he replied: "If you can solve it, it is an exercise; otherwise it's a research problem."
