mnemosyne

Unfortunately there's no sign of progress on the Mnemosyne research project, it looks unlikely to ever happen at this point.

Both Anki and Mnemosyne are based on the algorithm of SuperMemo 2(its version is 16 now).

Other people probably use Mnemosyne which is great but having space repetition in Emacs?

Spaced repetition(with mnemosyne) worked very very well for me when I was preparing for GRE's verbal section.

Can you consider sharing your Mnemosyne deck about Ruby and other technology?

There are a number of SRS clones already produced for the iPhone in the store (Mnemosyne, I understand, works fine on OS X); there's also a Mnemosyne clone in early development for the iPhone.

The first thing I'm going to be using Mnemosyne for is scheduling guitar practice.

Because Mnemosyne seems cleaner, and its author is doing some research on human memory which made me think that its algorithm could be better than Anki.

I use mnemosyne as my repetition software which allows me to insert images - and I can also annotate my cards with latex.

I use SRS (mnemosyne) with my kids for learning and it's awesome.

Certain problems exercise a wide variety of important techniques very quickly; I use Mnemosyne to prompt myself to re-work certain problems every so often.

When I was considering the alternatives, I chose Mnemosyne instead of Anki.

It's not much of a "useful" manager to me though, so I'm using Mnemosyne to generate the passwords and 1password to store them.

If you want to go further, strip out voice clips from these TV and movies and put them into an SRS system (Anki, Mnemosyne, etc...).

Supermemo isn't really free - maybe you meant 'Anki & Mnemosyne'?

Other more generic SRS programs include Anki and Mnemosyne.
