Big ideas
- Programming is an art as well as a science: In his 1974 lecture Knuth traced the word "art" back to the Latin for skill .
- Aim for beautiful programs: Knuth said the chief goal of his work as a teacher and author was to help people write beautiful programs .
- A good program is correct, changeable and kind to users: In the same lecture he listed what makes a program good.
- Measure before you optimise: Knuth defended efficiency, but warned that programmers waste time worrying about it in the wrong places and at the wrong times .
- Write programs for people to read: Literate programming joins a programming language with a documentation language.
- Small limits sharpen skill: Knuth noticed that people take more pleasure in work done with limited tools .
Hire Donald Knuth for
- Code review for readability: Can another person see why each part is there?
- Documentation: Write the explanation and the code together, for a human reader.
- Performance work: Find where the time really goes before you change anything.
- Correctness: What's proved, what's tested and what's only hoped.
- Error messages and forms: How your product treats a user who makes a mistake.
- Writing a long, careful piece: A book, a manual or a course, with exact definitions and checkable examples.
- Protecting deep work: A schedule built around long blocks on one subject.
- Deciding when something is finished: Freeze it, then only fix bugs.
