I'm Christian Lawson-Perfect.

My main homepage is at somethingorotherwhatever.com.

I also blog about maths at The Aperiodical.

checkmyworking.com began as place to put notes about my PhD work, before I abandoned it.

I also used to post about maths things, before I started The Aperiodical.

Now (in 2022), my plan is to use this site to post bits and bobs about the techy things I'm doing, for the sake of anyone else who might encounter the same problems I do.
