Software developers Rules #41

-

 


Don’t gold plate.  Work to the requirements and if you have an idea to do something more / different / better, follow the change management process.  I have seen more problems created by "Oh, it was easy to add, so I just put it in" than any other single cause.

Don't hide problems.  If something isn't working, don't hack in workarounds.  Find the root cause.  The more layers of convoluted crap that gets into the code, the more difficult and expensive it becomes to test, maintain and upgrade.

Keep it simple.  I used to work with a developer that just loved to prove how smart they were by building these stupidly complex patterns and expressions.  I don't care if you can jam 23 lines of code into a single 70 element long expression.  It's going to create a problem for anyone trying to decipher and maintain it in the future.  The simpler and more straightforward the code and logic, the better it is for the customer and the team who has to support it.

Document the crap out of everything.  Assume that someone looking at your code has just dug it up out of a code vault 20 years from now and has none of the background that you have.  They need to be able to understand what you're doing and why.  Document accordingly.  I just assume that this is a way of paying it forward.  I will one day be in that situation of having to debug someone else’s code and that person may have seen my documentation and learned to emulate it. 

Build for reuse.  This is less of an issue these days than it was in the time of monolithic mega-programs.  I learned to code on systems where you had to fit code into 4k overlays.  You learn to modularize functionality and find neat ways to build complex systems "Lego-style". That was really the precursor to object oriented design and development and its part of most modern languages. But I still occasionally come across code that's written as 100,000 lines in main () (or the equivalent) with a handful of callouts. If there was every justification for beating sense into someone, that's high on my list.

Levels of Programming #47

Successful Programmers who are both well-known businesses and around their code - full businesses - probably run full businesses. These programmers have given themselves zero real freedom: the freedom to decide for themselves what they want to do. And that freedom to share with their fellow programmers. This is the level that most programmers need. Reaching this level is often more based on professional skills than programming.    Famous programmer It's also a good place, but not unless you have a day job. You are famous in programming circles. But being famous doesn't mean you can turn a profit and support yourself. Famous is good, but successful is better.   working for a small, well-known technology company, an influential small company, or you may be part of a modest statup team. Anyway, other programmers have heard about you, and you have made a positive impact on the field.   Dead Programmer This is the highest level. Your code has survived and your...
