  - by Nissan Fan

  What would a simple unit test look like to confirm that a certain controller exists if I am using Rhino Mocks, NUnit and ASP.NET MVC 2? I'm trying to wrap my head around the concept of TDD, but I can't see to figure out how a simple test like "Controller XYZ Exists" would look.

• Python: Multi list comprehension, is there such an unwieldy beast of prey ?

  - by bandana

  consider the following python 'code'. it demonstrates the concept of a multi-list comprehension: start = ['a', 'b', 'c'] middle = ['r', 'a', 'a'] finish = ['t', 'r', 't'] l = [s.upper() + m + f for s in start, m in middle, e in finish] >>> print l ['Art', 'Bar', 'Cat'] Alas, the above code does not work in python. What would be a good approximation of multi-list comprehension in python? Please discuss what happens when the lists have different lengths.

• Public Private Key Encryption Tutorials

  - by Jake M

  Do you know of a tutorial that demonstrates Public Private Key encryption(PPKE) in C++ or C? I am trying to learn how it works and eventually use Crypto++ to create my own encryptions using public private keys. Maybe theres a Crypto++ PPKE tutorial? Maybe someone can explain the relationship(if any) between the public and private keys? Could anyone suggest some very simple public and private key values I could use(like 'char*32','char/32') to create my simple PPKE program to understand the concept?

• Web Application Auditing

  How can I audit a web application specifically database changes, when the application is connecting to the database as a system account?

I have read a few articles on identity flow but I do not fully understand the concept.

• Load image from string

  - by zaf

  Given a string containing jpeg image data, is it possible to load this directly in pygame? I've tried using StringIO but failed and I don't completely understand the 'file-like' object concept. Currently, as a workaround, I'm saving to disk and then loading an image the standard way: # imagestring contains a jpeg f=open('test.jpg','wb') f.write(imagestring) f.close() image=pygame.image.load('test.jpg') Any suggestions on improving this so that we avoid creating a temp file?
