Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Design rules

Free O'Reilly books and convenient script to just download them.

How to use:

Take the download.sh file and put it into a directory where you want the files to be saved.
cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.
