[Speakers] CONFIRMED February 2004: Bruce Moxon - Cluster Computing Data Management: Experiences and Best Practices]

Info about February speaker...

Joyce, there is no "list.svlug.org" -- that's why this message never
made it to the list; probably the whole thread didn't.

> >   Most human-computer interaction work has focused on end users of
> >   computing systems. Another important class of computer users,
> >   however, is the cohort of administrators who design, build, maintain
> >   and troubleshoot computer systems. These highly-expert users are
> >   vital for the operation of our "e-everything" world, yet little
> >   effort has gone into studying their work and developing tools that
> >   help them be effective. This is especially important because the
> >   labor associated with operating large computational systems is
> >   increasingly outstripping the cost of the technology itself.
> >
> >   Our research group is performing a series of ethnographic studies of
> >   system administrators in their work environments. This presentation
> >   will include results from these studies, as well as information
> >   developed at a CHI2003 workshop on system administrators as users;
> >   this workshop brought together researchers, developers, and
> >   practitioners from industria and academia.
> >
> >   From this group and from our own work, a consistent set of paradoxes
> >   is beginning to emerge. First, tremendous effort has gone into the
> >   design of powerful GUI tools for system administration. Many tools
> >   have been developed and validated with established user-centered
> >   design methodologies. Yet field studies repeatedly find system
> >   administrators ignoring these tools and falling back on the standard
> >   command shell and least-common denominator tools such as 'grep' and
> >   'vi'. Second, system administration is a highly collaborative
> >   activity, with a heavy dependence on instant messaging, email,
> >   telephone, and face-to-face interaction. Yet system administration
> >   tools rarely include collaboration aids, instead seemingly assuming
> >   that these workers toil away silently and alone. Third, effective
> >   operation and problem resolution requires an accurate mental model
> >   of how the system functions. "Situation awareness" theory dictates
> >   that a model starts with sensory input, develops with mental
> >   comprehension, and results in predictions of system behavior. Yet
> >   large-scale systems have few and unintegrated sensing mechanisms,
> >   and are too complex for any single person to comprehend, resulting
> >   in unpredictable behavior.
> >
> >   This presentation will illustrate each of the three paradoxes with
> >   examples from field experience, and offer suggestions for how the
> >   HCI community can move forward to resolve them.

> >   Rob Barrett is a Research Staff Member at the IBM Almaden Research
> >   Center in California where he works in the Services Research group
> >   that aims to bring value from human-computer interaction research to
> >   the IBM Global Services organization. His current work focuses on
> >   the user experience of system administration and human aspects of
> >   autonomic computing. Previous work includes an intermediary approach
> >   to designing web applications, optimization of pointing devices,
> >   track-following servo systems for tape data storage, and
> >   atomic-scale imaging. He holds a Ph.D. in Applied Physics from
> >   Stanford University and has earned masters and bachelors degrees in
