about
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.

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.

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_a7dab8S4@solipsys.co.uk

Email sent there and quoting the element name will pass my spam filters. After that we can use "proper" email addresses.

The version I'm describing has it physically sitting in front of you at the time, so you can see that the colours haven't been changed "on the fly" after you pick an edge. In this…

I can certainly explain it more, a question of "better" is debatable! Here's the process: (A) You give me a graph to 3-colour; (B) I claim I can 3-colour it; (C) You demand that I prove…

My understanding is that there is a difference between the concept of a Zero-Knowledge Proof (ZKP), and then the applications that such a thing is possible. In the example given, I can prove that N is…

Too late for anyone to see this comment, and it's just a trivial bugbear of mine, but the article has this: > "... meaning a radio signal will take a full 24 hours—a full light-day—to re…

Tech people have done this for years ... now it's hitting the "mainstream".

I rarely post this, I usually just let things go. But quoting from the guidelines[0]: On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If yo…

There is no way that you can sue the people responsible for DDoSing your system. Even if you can find them ... and you won't ... they're likely as not either not in your jurisdiction (they …
