Rational behavior requires theory. Reactive behavior requires only reflex action.
—W. Edwards Deming

Debugging dominates development time, and getting a working system out the door is usually less a result of brilliant design than it is of managing not to trip over your own feet too many times.

One of my most productive days was throwing away 1,000 lines of code.

The Unix Philosophy is bottom-up, not top-down. It is pragmatic and grounded in experience... It encourages a sense of proportion and skepticism - and shows both by having a sense of (often subversive) humor.

[Disciples of Unix @DisciplesOfUnix]

A simple reminder of what The Unix Philosophy encourages in us:

This is the Unix philosophy: Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.

If you do not know how to ask the right question, you discover nothing.

#TUP #TAoUP #DOTaDIW

[Disciples of Unix @DisciplesOfUnix]

[2/2] It is discoverable when it has facilities for monitoring and display of internal state so that your program not only functions well but can be seen to function well.

#TUP #TAoUP #DOTaDIW

[Disciples of Unix @DisciplesOfUnix]

[1/2] A software system is transparent when you can look at it and immediately understand what it is doing and how.

[Disciples of Unix @DisciplesOfUnix]

The objective of designing for transparency and discoverability should also encourage simple interfaces that can easily be manipulated by other programs — in particular, test and monitoring harnesses and debugging scripts.

#TUP #TAoUP #DOTaDIW

[Disciples of Unix @DisciplesOfUnix]

Because debugging often occupies three-quarters or more of development time, work done early to ease debugging can be a very good investment. A particularly effective way to ease debugging is to design for transparency and discoverability.

[2/2] On the other hand, it has a wildly creative side where the boundaries of imagination are the only real limitation!

[1/2] It's the only job I can think of where I get to be both an engineer and an artist. There's an incredible, rigorous, technical element to it, which I like because you have to do very precise thinking...

[Disciples of Unix @DisciplesOfUnix]

We should continually be striving to transform every art into a science: In the process, we advance the art.
—Donald Knuth

#TUP #DOTaDIW #TAoUP

[Disciples of Unix @DisciplesOfUnix]

Unix has a culture; it has a distinctive art of programming; and it carries with it a powerful design philosophy. Understanding these traditions will help you build better software, even if you're developing for a non-Unix platform.
