We discuss our most recent determination of the rotational period from longitudinal magnetic field measurements and H variability -- the latter obtained from over a decade's worth of professional and amateur spectroscopic observations. ... We concluded that the dipolar field of HD 57682 is characterized by a polar strength of 1.7 kG, and a magnetic axis aligned within 10 to 50 of the rotation axis, depending on the inclination of the rotation axis to our line of sight. ...

... Martin Bly and I have agreed to lead the Linux BOF at this year's ADASS and wish to invite you to attend. Since the BOF wasn't final until just last week we are still trying to organize a list of speakers willing to give a short (5-7 minute) presentation on work they have done, or some aspect of working with Linux that may be different from the normal workstation environment (e.g. writing device drivers for new instrumen- tation, managing large networks of systems, etc). ...
