Dowwie

I'm working full time porting the vast majority of Apache Shiro, a robust security management platform-framework written in Java, to Python 3.  Porting is a massive undertaking and I could use some help.  I'm working as quickly as possible, making things pythonic as I go.  Interfaces and abstract objects will come last and any major refactoring will come even later.  I have to get my arms around this beast first.

email me at [email protected] if you are interested in working together on this project

thanks to Les and Apache for making Shiro happen

It's not a question of *IF* this porting project will finish but *WHEN* -- the sooner I get help, the sooner the python community can benefit

Some patterns for fast Python. Know any others?

• Avoid overengineering datastructures. Tuples are better than objects (try namedtuple too though). Prefer simple fields over getter/setter functions.

• Built-in datatypes are your friends. Use more numbers, strings, tuples, lists, sets, dicts. Also check out the collections library, esp. deque.

• Be suspicious of function/method calls; creating a stack frame is expensive.
