    The Search for New Unigroup Meeting Space:

    Unigroup would like to thank the handful of people who have been
    looking for, checking on, and/or suggesting potential new meeting
    locations for our meetings!  The search for an ideal location is
    still proceeding.  In the mean time, we have found a location in
    SoHo to hold our July meeting.

    Meeting Planning:

    Our FreeBSD Networking Stack meeting had to be postponed
    due to speaker unavailability, but it will be rescheduled when
    our speaker George Neville-Neil of the The FreeBSD Project Core
    Team is available again.  We hope to cover recent advances in
    the stack, including recent support for 10G Ethernet.

    We are planning a Launch Meeting (at Sun) for upcoming releases
    of Solaris (and OpenSolaris Project Indiana).

    Novell is also interested in hosting a meeting on SuSE Linux
    (possibly on the Real-Time Linux Kernel, which was being
    demonstrated at the SIFMA 2008 show).

    We are also working on a potential meeting on Linux Real-Time
    Messaging (as used in financial/trading systems).

    This Month's Meeting:

    For our July 2008 meeting, many of you will recognize our
    speaker Brian Gupta, who is a Unigroup member, and a leader
    in the NYC OpenSolaris User group.

    Topic: Server Performance: Deploying and Scaling (Ruby on) Rails

    database optimization, and caching.  In addition we will cover some
    tools and techniques that you will start to need as your site grows.
    These tools range from monitoring and management, to load testing
