[$] Rusty's reminiscences

Rusty Russell was one of the first developers paid to work on the Linux
kernel and the founder of the conference now known as linux.conf.au (LCA); he is
one of the most highly respected figures in the Australian free-software
community. The 2019 LCA was the
20th edition of this long-lived event; the organizers felt that it was an
appropriate time to invite Russell to deliver the closing keynote talk.
He used the opportunity to review his path into free software and the
creation of LCA, but first a change of clothing was required.
