Noot: Spaced repetition flashcards

I've been curious about learning Meteor and am wondering if a social flashcard app would be too much for it to handle.

All that said, I agree. Anki is one of the most useful pieces I software I have ever encountered.

To anyone who is on the edge about using SRS I recommend downloading it onto computer and phone and getting a good shared deck to build the habit. Building your own decks is superior but really, just start.

1) Copy paste of images. This is key. With my mac I screenshot a slide from an anatomy atlas to the clipboard. Then use the image occlusion editor to hide labels on the slide, and then I use the editor to highlight a certain area on the slide and ask "what is this muscle?" 70% of my cards require copy/paste of images. Without this feature I could never switch.

2) Cloud storage that synchronizes flashcards on my mac and mobile device. I do a lot of flashcard review in the gym, bathroom, waiting in line, etc. Without mobile I could not switch.

3) Searchable index of cards. I make a flashcard for every major piece of information that I need to know for school, and I use search to connect that information. For instance we spent the last 6 weeks learning about metabolic pathways and what factors regulate enzymes within them, but we never focused on specific regulators. With Anki, however, I can search for a certain activation enzyme, say protein kinase A, and then have a deck of flashcards showing me what pathways are affected by said enzyme.

Those are the biggest must have features for me that set Anki apart. There are loads of great minimal and social flashcard applications (eg Study Blue or Quizlet) available for average users, eg, someone learning spanish. You'll have to find a way to stand out from them.

There's no excuse for you to use Leitner though. Anki is based on the SM-2 algorithm which is well-documented (though only a starting point).

How accurate can your spaced repition algorithm predict my forgetting curve? The time between repitions can be substantially different depending on the answer I give to Anki (a day between a week or something like that)

In which other aspects do you want to be like Rdio? Closed source, analyzing user data, advertisement, monetization?

Just fyi, I recently hacked something up that did exactly this, using a bit of csv parsing in python and ffmpeg to extract the clips. It wasn't too hard to write, though I can see it becoming more difficult if you want more sophistication.

Seriously?

Do you sometimes sneeze and, in the process, integrate your projects with external code (that isn't even packaged as a library) and push it out to users in one fell swoop?

It's far more "dangerous" to have any proprietary software "around" -- if you somehow violate that license, you'll face a lot worse consequences than if you violate the AGPL.
