  code-quality bug
  Do other people fix bugs when they see them, or do they wait until there’s crashes/data loss/people die before fixing it?Example 1Customer customer = null;…customer.Save();The code is clearly wrong, and there’s no way around it – it’s calling a method on a null reference. It happens to not crash because Save happens to not access any instance data; so it’s just like calling a static function. But any small change anywhere can suddenly cause broken code that doesn’t crash: to start crashing.But, it’s also not inconceivable that correcting the code:Customer customer = null; … customer = new Customer(); try…customer.Save();… finallycustomer.Free(); end;might introduce a crash; one not discovered through unit tests with complete coverage, and manual user testing.Example 2float spee

  javascript quality software-quality code-quality
  I have been in the process of learning Javascript to complement ASP.NET. I have a strong background in general programming, and have always been an advocate of disciplined practices and good hygiene to reduce the error count in code.However, the language that Javascript is seems to make this very difficult. Its dynamic and interpreted nature seem to push error detection to the last point possible in the cycle. For example,
