SLUUG Elections at February Meeting

>>>> N O T I C E <<<<

The St. Louis UNIX Users Group (SLUUG) will hold its annual election of directors and advisory election of officers on Wednesday, February 11, 1998, at the regular monthly meeting.

Elections will be held for two three-year positions on the board of directors. Currently, these positions are held by Joe Bohnenstiehl and Steve Totten.

The SLUUG board of directors is responsible for appointing the group's officers (President, Vice President, Secretary, and Treasurer). The board traditionally appoints these positions in a manner consistent with the recommendations of the entire membership body based on the results of an advisory election. Thus, an advisory election will also be held for these four officer positions. These are one-year commitments. Currently, these positions are held by:

    President                 Gary Meyer
    Vice President            Rich Seibel
    Secretary                 open
    Treasurer                 Steve Pautz

All members in good standing are encouraged to vote. To be a member in good standing, you only need to have attended at least two meetings in the past 12 months (Special Interest Group and Steering Committee meetings are included).

Remember, this is your organization. Be sure to attend February 11 and cast your vote!

St. Louis Java SIG

Brian Gilstrap of Technology Applications, Inc., will compare and contrast distributed object computing with Java RMI and CORBA.

CORBA (Common Object Request Broker Architecture) technology, defined by the 800+ member Object Management Group (OMG), provides a vendor-neutral, language- and platform-independent mechanism for creating distributed object applications. It hides most of the messy details of network communications allowing the developer to concentrate on more important application level details. Brian Gilstrap will compare and contrast CORBA and Java RMI, which was presented by Mark Volkmann last month.

Next meeting details:

  When:    Thursday, February 12, 1998, 6:30 PM
  Where:   Novell, Inc., 600 Emerson Road, Suite 203

Processor Evolution From VLIW to EPIC
the Foundation of Intel's Future Architectures
by Mr. Phillip Newell,Boeing St. Louis

When: Monday, February 9, 1998 Social & Dinner: 5:45 PM. Program: 6:30 - 7:45 PM
Where: Grones Cafeteria: 4409 Woodson Rd, 423-7880

Abstract: Intel has revealed that Explicitly Parallel Instruction Computing (EPIC) is the basis for their future processor architecture, the IA-64, which is expected to be in production in 1999. EPIC development was based on experience gained in the Very Long Instruction Word (VLIW) architecture of the now defunct Multi-Flow Computers. This discussion will be launched by an overview of VLIW and available information about EPIC. The overview of VLIW will include a brief video from MultiFlow. Biography: In the early 1990s Philip Newell led a full-day Seminar in High Performance Computing for the St. Louis Chapter. A key point was that the technologies then used in Supercomputers would over time flow down to everyday processors. VLIW was one of the technologies discussed. During the 1980s and early 1990s, Mr. Newell was highly involved in McDonnell Douglas' efforts to take best advantage of high performance computing technologies. He is currently a Sr. Information Technology Specialist with McDonnell Douglas which is now a wholly owned subsidiary of The Boeing Company. He has been the Chairman of the St. Louis Chapter for 10 years.

St. Louis User Interface Society

When: Wednesday, March 4, 1998, 7:00 - 9:00 PM

Organizational Meeting and Intranet Design Workshop

The Intranet Design workshop will provide participants with a hands-on opportunity in practicing user-centered design techniques to create web pages for an intranet site. Paper prototyping will serve as our primary technique, allowing for us to quickly design web pages, test them with users, modify the design, and test again. Joe Grant and Karen DuBrucq of Tripos, Inc. will be among the facilitators for this workshop.

This workshop requires only your interest, but please reply to this email to indicate that you plan to participate, since we do have a limit on the attendance.

Before the workshop, our organizational meeting will address several topics that should significantly move forward the progress of this professional society's interests.

Please consult the St. Louis User Interface Society web site for the latest and most recent meeting information, including the agenda and detailed directions to the March meeting.
