Computer OSes

  • May 27: Debian Lenny source packages were moved to archive.debian.org. FB updated the packages to reflect this.
  • May 27: aptitude on wolverine found more than 65535 (16bit limit) packages to update, causing a bug. FB updated the apt cache size, then updated the distribution source by source.
  • May 27: current status = we have the final versions of all Debian Lenny packages (gcc 4.3.2, python 2.5.2, pygtk 2.12.1, gtk 2.12.12)
  • May 28: also upgraded lothlorien to ease work on CHAMP

CHAMP -- hardware

  • May 26: Larry started pumping CHAMP
  • May 27: vacuum ~ 2e-3
  • May 28: vacuum reached 1.0e-3, so not quite ready for pumping.
  • May 29: CHAMP cool, pressure ~7e-7
  • May 29: Despite attempts to reproduce hardware crashes/freezes from last run, none have happened so far.

CHAMP -- software

  • May 28: fixed CVS that had been erased from ctrscrut due to a HDD failure in Jan/Feb. Fixed all memory leaks on spooler and astropci reported by cppcheck, especially realloc issues. Reintroduced star info and uv info to spooler, hopefully compatible with CHARA libraries (tests TBD).
  • May 29: worked on spooler code, now fully functional, i.e. star + uv info (though this uses partially the old method).
  • May 29: tried to reproduce the "negative ftnum bug" but could not.
  • May 30: cleaned up a lot of the python code to implement calibration/automatic search.
