1938 Rolleiflex

The camera is a Rolleiflex Automat, its from around 1938 they were produced from August 1937 - March 1939
My first ever 120 picture. I developed it in a makeshift darkroom in the bathroom and completely guessed the development time because i was using an uncommon developer

A Python dispatcher pattern

import sys
##  the format of the dictionary is as follows:
##  'command': {'sub command' :
##    {'function':'module.class.function'}
##  }
dispatchDictionary = {
'add' : {'friend' :
{'function':'core.friends.friends.addFriend', 'help':'blah'}},
'connection' : {'info':{'function':'core.class.function','help': 'prints help'},
'help' : {'function' : 'core.shell.help.print_help'}},
'list' : {'files' : {'function' : 'core.shell.file.f_list'}},
'get'  : {'file' : {'function' : 'core.shell.file.f_get'}}

RSA update

I've now placed the code on github. In its current state it compiles with no errors but does not work completely correctly. I think i missed something somewhere, i will rectify the problem and post when its 100% done.

RSA module for Python

I'm currently developing a Python module in C for the RSA public key algorithm. The key generation is done and the encryption and decryption are mostly done. The module relies on GMP and is its only require, other than Python of course.

I will have more updates and a link to the code as soon as im done.
for now read here and here.
