Every once in awhile I happen upon some mention of one of the first open source contributions that I made, an XInput driver and notes to get a Calcomp DrawingSlate tablet working with XFree86 3.x. That was years ago; more recent versions of XFree86 include built-in support for Calcomp tablets courtesy of Martin Kroeker. Yet, funny though it may seem, my old hack still gets top ranking in Google when you search for "calcomp xinput".
(Speaking of time warps, as I write this, it's 2:00am June 15. I forgot that, when I post to Advogato, I'm in California where it's still yesterday.)
