Review of minutes from the last meeting

    We looked at the [28]minutes from the last meeting. Elliott remarked
    that in the translation tables there was no need to identify the
    pre-amps for the tracking chambers as separate entities.

Status of the CCDB release

    Dimitry is finishing the conversion from existing Subversion-controlled
    calibration constant files to the CCDB
      * built JANA, put in classes to read CCDB
      * getting ready to test
      * should be done in the next few days
      * CCDB has been checked into the 12 GeV Physics repository

    Elliott commented that some progress on the conditions part of the CCDB
    would be useful.

Update on non-deterministic event reconstruction

    David has found and fixed a problem, first [31]reported by Will, where
    repeated reconstruction of the same events with the same binary
    reproduced different results. See [32]David's message for details of
    the fix.

    Paul [33]reported a different bug and checked in a fix. This was giving
    different figure-of-merit values for repeated executions at the 1%
    level. See his message for details.

Miscellaneous Discussion

      * We discussed using NaN (not a number) as a signal that a variable
        is not defined.
      * We discussed a problem with the new hit generation in the tracking
        chambers where the maximum number of hits is reached. Simon will
        raise the limit in the software.
      * Dave asked Paul when the high-level particle class reorganization
        would be finished.
      * Dave wondered if the Subversion servers could be configured to
        store passwords in an encripted form.
      * Will pointed out that the weekly b1pi jobs are not regularly looked
        at for success or failure. He volunteered to help with this. Dave
        pointed out the utility root2email that might help with
        notification.
      * Mark noted that the nightly build was now broken. This has been the
        case since the change in the roster of ifarm machines.
