                      Safety-Critical Software Development

Users of systems, both ordinary and sophisticated, see a larger percentage
of system function being controlled by devices containing software.
These devices most often operate as intended, but sometimes contribute
to accidents or adversely affect safety-critical functions. To minimize
and control hazards in safety-critical systems, hardware system safety
engineering practices must be rigorously applied to software development.
Good engineering practice is as applicable to software engineering as
it is to the other portions of a system, but application to the special
characteristics of software is seldom done adequately.

At our December meeting, John Cosgrove (PE, CDP, Consulting Engineer)
will discuss safety-critical software development. His talk will be a
short version of a course he gave at the most recent Wescon. It includes
the reasons for the growth of software in safety-critical systems, an
examination of "lessons learned", a method to identify safety-related
software requirements at an early stage, and some promising new developments.

The UUASC is for all persons using Unix either personally or professionally,
or interested in learning more about Unix. We recognize all varieties of
Unix, including (without prejudice) SCO, Linux, SVr4, Solaris, AIX, and OSF.
This is a good place to meet others with similar interests and broaden your
skills and knowledge. Generally, meetings include a technical presentation
on a hardware or software topic of current interest to the Unix community
and a round-table discussion of current topics of interest to the group.
We are always looking for interesting presentations and your suggestions
are most welcome.

Please join us this month and bring along your friends or co-workers. Also,
please forward this announcement to others who may be interested and feel
free to post it on BBSs, both electronic and physical. If you receive more
than one announcement by email, please let us know so we can keep our lists
current. Thanks for listening.
