1. Simplicity is essential
2. Solve problems instead of creating them
3. We are not smarter than others, others are usually not smarter
4. Do everything yourself
5. Strive for robustness
6. Do not think you can make computing "secure"
7. Use input devices when they make the most sense
8. Avoid all ornaments
9. Tools are just tools
10. Be humble
11. Don't work for free if you do not enjoy it
12. Do not listen to others

Software is a way to get something done.

The followers of the Code It Yourself Manifesto believe in these things:

• We implement it according to our own goals.
• We make mistakes and learn from them.
• We learn how our tools we depend on need to work.
• We gain a deep understanding of our problem domain.

Another manifesto. Thanks for it. I add it to the collection.
