Twenty years ago, Wozniak realized that computers could easily calculate the moment of forgetting if he could discover the right algorithm. SuperMemo is the result of his research. It predicts the future state of a person’s memory and schedules information reviews at the optimal time. The effect is striking. Users can seal huge quantities of [...]

Usually, the response to a test program that demonstrates a bug in the system is to fix the bug. In this case, the underlying algorithm is the bug. What’s the error? [...]
Read more →So I think I’ve found a perfect game. I haven’t played it yet, and there are some details to be figured out, but I think it’s pretty clearly potentially a good abstraction for a certain class of mathematical and political issues, and also looks like it could be quite entertaining if you’ve got a taste [...]

The ANZAC research institute may be on to something big here though it looks like it might not be going anywhere with [...]

As such it runs directly contrary to a lot of established wisdom. To really get into the details of why I think it [...]

It gives a pretty good overview of some important models for [...]

Seems to me like this ought to be something one can check with, say, sale prices or other financial performance metrics.

The procedure was made possible after an altruistic donor – neither a friend nor relative of any of the six patients – was found to match one of them. Five patients had a willing donor whose kidney was incompatible [...]

In his version of the theory, he argues that man will not evolve further. “I see God’s hand at work through the mechanism of evolution. If God chose to create human beings [...]
