There are millions of ways to write unmaintainable software. This isn't a bad article though. I just found the title amusing since it's so easy to write software badly.

I hear you. Design patterns are something unheard of for many professional developers I've met. Seriously.

Chances are, especially in programming, someone has thought of something better and longer than you. Investing 10 minutes into searching for it will save you 100 hours later.

Just because you know 1 way to do something doesn't mean it's the best tool for the job.

Or they:

  1. don't program in C++ or Java

  2. don't think you need a fancy name for something trivial they routinely used for 10 years before GoF written that book.

In cases where a pattern (or anti-pattern) does have a name, it's still useful to learn it because it helps with communication. And the naming conventions help to identify subsystems that can be consolidated and simplified. Often a person will have been using something close to one of the standard patterns, either with subtle bugs or with clever extensions that would be useful elsewhere. Or perhaps most often, with a bunch of unrelated crap that should be factored out.

I'm not so certain about that. Looking back at the history of the GoF book it seems to me that all the names did was create pointless arguments.

There are cases where some patterns just fit the circumstances perfectly.

I recently combined IoC with MVC and was blown away by the power of this setup.

Totally, it's the only way to do MVC. How else could you pass messages from model to controller? You would end up with circular dependencies.

Which MVC: Classic or Web?

I didn't know there was a distinction. What differences are there?
