submissions / comments / favourites

If you want to contact me, find me on the web. I am especially interested in math, juggling, programming, and education, and since there are other people with my name you'll probably need to include at least one of those terms in any search.

I was once a prolific contributor and commenter, but no more. I go through bouts of submitting stuff, but then go and disappear for lengths of time. If there is something you'd like me to see or comment on, you can email me. Don't ask me to upvote things. If it is interesting (to me) then I will.

To contact me about the idea of spaced repetition by experiment, use this address:

I used to have an email here but it got harvested by spammers - I'm looking at you, - so it has been removed. This is a temporary one:

HN_a7[email protected]

Update: That email address has been harvested and is now being spammed. Emails sent to it will result in the sender being black-listed. To send me email, add one to the username. That will get you automatically white-listed.
