I was born in Hereford in 1981 and I currently move about a lot. I grew up in Herefordshire, Oman and Surrey; more recently China and Malaysia. I attended Royal Holloway university where I read Computer Science. I put this paragraph in because you'd be surprised how many emails I get for other Henry Todds.

When I’m bored I tend towards online puzzles: the Times Crossword (the easy one), Nurikabe, chess and so on — see my puzzle bookmarks for more.

I keep a reading list, although I’m not as fastidious with its maintenance as I might be.


If you would like to get in touch, please email me at henry@hjst.org. My key ID is 0x47E3A921.

I leave a terminal connected to various IRC networks, the most public being OFTC & Freenode, where my nick is just my initials (hjst). It’s not the most reliable way to contact me, but you can try pinging me anyway if you like.

You can also find me on Skype as henry.j.s.todd. I don’t leave Skype running, so you will need to send an email first to arrange a time for a call.


You can find me on Twitter, GitHub, Lobsters, LinkedIn and elsewhere if you search for “hjst” or “henrytodd”.


I use Pinboard to store all my bookmarks, including articles and links I think are interesting and worth sharing. My public bookmarks tagged with journal form a link-blog of sorts.
