I have been absent for awhile, and much has happened.  No-one is waiting for me here, of course; I'm not a syndicated columnist whose absence people would note.  But I have missed the OS community, reading and commenting and contributing.  And I believe I am ready to contribute again.

I hope to write, possibly this evening, with a bit of an update, or perhaps just another riff of some sort.  Meanwhile, I hope anyone who sees this is well in the depths of the summer.
