Please recommend resources to learn design patterns.

Question

There were some questions that got answers with books specifically, but I wonder if there are any other non-book good resources (pages, blogs, online tutorials) to learn design patterns.

Answer 1

Start from the wikipedia article about design patterns. The list to specific pattern articles is quite nice.

Also, don't forget to take a look at anti-patterns as well - knowing how to avoid most of them is arguably at least as useful as learning the design patterns :)

Answer 2

The wikipedia article is a good start and generalised, but gives you a good overview.

The issue is that there are not very many blogs or posts or online tutorial relating to the generalised 'design pattern' - more based around one particular design pattern (MVVM, MVC, Adapter, etc).

As much as you say you're not interested in a book, I'd definitely recommend Head First Design Patterns - an excellent book for the design pattern newbie.

Answer 3

IMO Design Patterns is one of those areas where learning from blogs/online tutorials alone can only lead to dangerous half-knowledge. Blogs often try to argue a controversial views instead of explaining the topic, which can easily lead a beginner to get a skewed impression of the topic.

Get a good book and read it first. Then you'll be able to really get something out of blog discussions. (FWIW I'd suggest the "bible" by Gamma et al.)

Answer 4

Learn Smalltalk. A large amount of the classic design patterns originated there, and it will give you a different view of several common patterns than you might have otherwise.

Answer 5

http://www.dofactory.com/Patterns/Patterns.aspx this is the best for learning design patterns I've seen ever.........

Answer 6

I think Hillside Group is one of the most powerfull comunity around design patterns.

Web site: http://hillside.net/
