Software developers are a very privileged bunch. We don’t have to work in dangerous environments, and our jobs aren’t physically taxing (though carpal tunnel syndrome is always a threat). We are paid to think about things, and then to write down our thoughts in the form of code. This code is then used and maintained by others, sometimes for decades.
Given this situation, I believe we all have a responsibility to write code that can be easily understood and maintained (and, c’mon, let’s admit our secret desires, admired) by developers who follow in our footsteps.
Steve McConnell’s http://www.construx.com site, along with his book, Code Complete (Microsoft Press), offers checklists on coding style, naming conventions and rules, and module definitions.
