The Power of 10: Rules for Developing Safety-Critical Code
When we write code for things that are very important, like planes or medical devices, we have to be extra careful to make sure the code is safe and won't cause any problems.
One way we do this is by following something called the "Power of 10" rules. This is a set of 10 rules that tell us how to write safe code.
1. Keep it simple: We need to make sure the code is easy to understand and not too complicated.
2. Use a coding standard: We should follow a set of rules for writing code so that everyone writes it the same way.
3. Use tools that help: There are special programs we can use to check our code and make sure it's safe.
4. Stay focused: We need to concentrate on writing the code and not get distracted by other things.
5. Use proofreading techniques: We should read our code over and over again to make sure there are no mistakes.
6. Test early and often: We need to make sure the code works the way it's supposed to by testing it many times.
7. Build in feedback mechanisms: We should include ways for the code to tell us if something goes wrong.
8. Use safe libraries: We should use other people's code that has already been tested and proven to be safe.
9. Don't trust anything: We should always be skeptical and check everything to make sure it's safe.
10. Keep it simple, again: This is so important, it's one of the rules twice! We need to make sure the code is not too complicated and easy to understand.
By following these rules, we can make sure that the code we write for important things is safe and won't cause any problems.
