Yes, I think there's some points we can generalize for all software there: - Readability counts. If you can't read the code, who could test or improve it? - Documentation needs to be cared for near the code, only then you have a chance it's not outdated - It's possible to improve correctness and efficiency at the same time (if your code is understandable) - Use the literature available - Code once holding high standards will need to be checked constantly too so it doesn't rot.
