I've left TCD for so long that this account is going to die sometime soon. Consider this site sleeping. Or dead. Any links to pages in here should work until the account is closed. But I'm not going to encourage any new ones. Sorry.
And the mail address that has been advertised here for the last long time is no longer useful either. Try fmdaly@maths.tcd.ie if you really want to find me. It should work for a while longer.
