basic SRS/anki/supermemo flashcard ruby web app

I need a basic flashcard webapp that supports users and user-made lists of flashcards. ? The users will be able to study from these lists, there will be an interactive mode that is designed for efficient learning. The learning mode will incorporate a SRS (Spaced Repetition System) algorithm. Explanation of SRS: [login to view URL] Example SRS web app: [login to view URL] ? (can just sign up with a random email, no need for confirmation email) Example offline SRS app: [login to view URL] ## Deliverables The web app should be coded in the fully idiomatic ruby and rails way. ? Do NOT apply for the job if you still use for-loops in ruby code! The code should be mostly OO, with classes and such. ? The controllers should be skinny, the models should be fat. Try to adapt the SRS algorithm from Anki. ? You can see the python code here: git clone git://[login to view URL] look at libanki/anki/[login to view URL] I actually have some ruby code for the SRS algorithm, but I will only share it with the winning bid. ? It's not adequate though, it can give you ideas or be improved to include Anki's refinements to the algorithm.
