  • Last week
    • Digging through the 550,000 lines of code of the LUCI system.
    • Met regarding LUCI sub-frame and AO requirements.
    • Lots of discussion of LUCI FITS headers, stale DD values, and AO.
      • The conclusion was that the AO system needs to be responsible for keeping its DD values up to date.
      • LUCI images were checked, and the data in the headers (calibration vs. non-calibration) seems to be acceptable.
    • Found that configuring LUCI in a VM which uses mDNS is tricky; some places need the FQDN (luci-sim.local) while others need the hostname (luci-sim).
    • Fixed the LUCI configuration in my VM and isola-luci; the configuration on osa-luci still needs work.
    • X2Go /XQuartz has been giving me a lot of trouble; it frequently locks up the session, disconnects, and has to be reconnected when running the LUCi GUIs.
      • ssh -Y, however, is unbearably slow, and there doesn't seem to be a better solution to the problem.
  • This week
    • Digging through the 550,000 lines of code of the LUCI system.
    • Preparing a new LUCI version for testing and deployment that will hopefully fix many of the open RTD issues (which are really Aladin issues).
