The spiped secure pipe daemon

Spiped (pronounced “ess-pipe-dee”) is a utility for creating symmetrically encrypted and authenticated pipes between socket addresses, so that one may connect to one address (e.g., a UNIX socket on localhost) and transparently have a connection established to another address (e.g., a UNIX socket on a different system). This is similar to ‘ssh -L’ functionality, but does not use SSH and requires a pre-shared symmetric key.

Spaced Repetition

One of the most fruitful areas of computing is making up for human frailties… My current favorite prosthesis is the class of software that exploits the spacing effect, a centuries-old observation in cognitive psychology…The spacing effect essentially says that if you have a question (“What is the fifth letter in this random sequence you learned?”), and you can only study it, say, 5 times, then your memory of the answer (‘e’) will be strongest if you spread your 5 tries out over a long period of time – days, weeks, and months
