Let's face it, all developers have written code in the past that they now regret.  Along the way, most also develop a mental list of the most egregious bad development practice to avoid in the future.  Eric Gunnerson, C# Community Coordinator at Microsoft, has posted his list of the Seven Deadliest Sins of Programming:

  • Excessive Coupling
  • Inappropriately Clever Code
  • Deferred Refactoring
  • Premature Optimization
  • Overuse of Virtual (C#) or Overridable (VB.NET)
  • Overuse of Inheritance
  • Premature Generalization
MVP and author Bill Ryan has a list of 7 Deadly Sins including more conceptual items, such as "making too many assumptions."

What's on your list?

    Making non-virtual the default for methods in an OO language? ;-) (It's probably the biggest design mistake in the C# language. Welcome to the 1980s and C-front, folks!) Peace, Cameron Purdy Tangosol Coherence: The Java Data Grid

    Although, I guess that could come under "deferred refactoring," considering that not refactoring would be deferring it for infinite time.
