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.

Submissions do not imply endorsement.

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

    SR_Expt@solipsys.co.uk

My spam filtering is pretty severe, but I've put the word "Dysprosium" on the allow-list - quote that and your email will get through.

(Note: That email address has been harvested, and is now receiving invitations to blogs, etc. If you want to get in touch, quoting the element name is needed)

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

HN_a7dab854@solipsys.co.uk

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