• JLab: Craig Bookwalter, Mark Ito (chair), David Lawrence, Simon Taylor, Elliott Wolin, Beni Zihlmann

Announcements

1. Mark reported that the change request, which was recently submitted to the project, for Offline Computing will have to be redone. The current version references last year's baseline BIA schedule. The request must reference the current revised schedule.
2. Elliott told us that Yelena Prok from CNU has summer students looking for projects. He would like to get a feeling for our need for students by the end of the week. Please contact him if you have ideas.
   • On a related note, David expressed concern that our plan to assign work to a new collaborator on the calibration database might result in a product incompatible with the current framework. He agreed to write a specification for the system to guide prospective work. Mark agreed to set up a meeting with David and Eugene Chudakov to discuss this issue.
3. David has successfully run our reconstruction on MacOS 10.6 (hdgeant is still problematic on this platform). Changes to support this have been checked in on the trunk.
4. On a topic possibly related to the offline, Elliott reports that Labview talking on EPICS appears to work.
5. Beni reported on a new system to edit an existing relational database, using MySQL and PHP.
   • Elliott urged caution using this combination; he has heard reports that it is vulnerable to cyber attack.
