Question

I am referring to exception messages that show the developer is incorrectly using an API. For example incorrectly passing a null to method. So the type of exception that the developer will get the first time they have run their incorrect code. The type of exception message that should never get to be displayed to the user of a system.

This is kind of related to the theory that since the programming language is in English then the programmer already has an understanding of English. Or at least enough to decipher an exception message.

And yes I know that the .net framework follows the “localize everything” approach.

Answer 1

Your question can be rephrased as “should all developers get the same error message so that they can Google it?” 😉

And the answer to that is yes.

Translation means that

• the message is no longer the same as whoever wrote the API intended. It might carry the same meaning, or it might have lost something in translation. It might be badly translated, and in some cases it might be downright unreadable.
• Whoever reads it can not simply type the error into Google and see what everyone else who got this error did. Because everyone else got the same error in a different language.

About .NET’s “localize everything” approach, it is horrible. I’ve been tripped up by it countless times, especially because if it is unable to find the localized resource, it does not give you the plain English version. It gives you a “Could not locate resource” error instead, effectively throwing away the actual error information.
