H A DCodingStyle.rst14 The code that you are afraid to touch is the code most in need of refactoring.
20 Good code is readable code, where the structure is simple and leaves nowhere
23 Assertions are one of our most important tools for writing reliable code. If in
55 can still incorporate that kind of thinking into our code and document the
58 code statically typed.
63 Good code is code where you can poke around and see what it's doing -
121 Spend time doing support and helpdesk stuff. Don't just write code - code isn't
132 idea until you start writing code.
163 reading lots of code and looking for common patterns and issues. Don't be
181 even better as a code comment.
