Summary of progress

Work activity; whether it reached associated milestones.


Bill (submitted on 2/16/2009)

  • Automated build system is much more mature
    • Trunk build is being tested properly (which in this case means that the build still fails for some packages)
    • Automatic incremental build of trunk on checkins, delayed by 1/2 hour after last checkin
  • Working on security document for PDR (finished any day now ...)
  • Security support -- installed one-time-password (OTP) for admin access to more LSST infrastructure machines at NCSA
  • Worked on new release of VMs with LSST stack pre-installed, for download by developers
    • Ray will actually install stack, and then I will release the VM images for download
