Jeff Hawkins can do more than revolutionary PDA’s. He has published a paper on a model of memory built up from very small pieces. I read a blog article on how this can relate to current systems such as a Bayesian network. The talk from TED is very interesting, and after hearing it I happened across a couple different articles that talk about the “tip of the tongue” phenomenon. They situations make a lot of sense when considered in light of this memory model. I read Marvin Minsky’s Society of Mind many years ago, and I think Hawkins has gone more in depth on one specific piece of this. The two works are self-reinforcing, in my opinion.
I found a tutorial on mapping keys in Vim. The same techniques work for Vimperator if you create your own configuration file. If you don’t like Vimperator though, you can search Firefox from within Vim.
