Periodic Table of Design Pattern Elements

Huston design patterns is the very nice site were I found the picture.

Python and design patterns – an example using pygame

A very usefull guide I recently discovered can be found over here.  It teaches multiple things at the same time : using python, introducing some design patterns ( the ones found in the model view controller pattern ) and at the same time developing a game using pygame…  What do you want more to get you started?  I will keep you informed about this guide.  I wish to thank the author for the nice job he did so far.

Anti-pattern overdose and bad smells

Today I was doing some occasional code reading.  In fact it was a colleague that let me read some source code he stumbled upon.  We never saw so many anti-patterns in one code read session : magic numbers, middle man, spaghetti code, very long functions with huge switch statements, code duplication, it was all there.  I was wondering what to do with this discovery : go to the author of this marvelous piece of code and explain our objections or refactor the code ourselves?  The former options seemed attractive but after reflecting a while I chose not to bother because, after all, the code worked and management does not care about clean, maintainable and optimized code.  So my colleague decided to refactor it himself…  I decided to do some research and write a tutorial, both for beginners and advanced programmers on how to properly design and write clean code using design patterns and be aware of bad smells in code…  The only problem remaining then will be on how to motivate people to put the theory into practice.  To be continued…
