Michael W Lucas is the author of fifty-odd books on topics ranging from Unix management to cozy mysteries. He's been a Unix user since 1987 and a sysadmin since 1995. If you ask him about how to make a living writing, BSD Unix, OpenZFS, DNS, martial arts, or pet rats he won't shut up, so consider yourself warned. He loathes the movie Laserblast so much, he wrote a spite book about it. Speaking of spite, he maintains the authoritative list of titles he's written in an SNMP table, but you can get a slightly obsolete version at mwl.io.
