I am ecstatic to receive corrections; I am happy to engage in correspondence, but usually only the most recent technote or two will be anywhere near the top of my conscious memory, and even then I am no expert and cannot guarantee to be able to offer any help over and above the technote itself. I will be very unhappy to receive questions which indicate you haven't read the technote thoroughly. Tom Yates.
Most recent technotes come first.
I have also more recently stated writing professionally for the august organ Linux Weekly News. I'm linking these articles here, with the most-recent at the top. Note that LWN's terms give them an exclusive right to redistribute for the first two weeks, so the top link at any time may only be available to subscribers. If you find that's the case, come back in a week or two - or subscribe, it's well worth reading.
