Team reports

MB

• Last week
  • OC, Management
  • learning some more about AO s/w, join discussions and scheming on #ao-sw
  • ATT/SW one-slide recap for the board
  • close swg recruitment
  • msgd/rtdb fedora/python3 for DMS, WIP
• This week
  • Performance Appraisals
  • git/github "policy" (= philosophy slides) for new staff

YZ

• Previous:
  • LBC alert list and MODS WCS program discussion with Olga.
  • RM507 machine setup meeting on Monday.
  • LBC controller swap (#4 -> #1, then back to #4), bias level measurement and adjustment (with Olga and Alessandro).
  • Argos swingarm testing/debugging with Paul.
  • TMS software share (with GMT) discussion??
  • Information Security Awareness Certification.
• Next:
  • Finish LBC alert list.
  • Continue MODS WCS work with Olga.
  • TMS meeting and software work.
  • Argos swingarm testing/debugging with Paul.

DE

• Windows server ping. Again. I'm trying to impress a sense of urgency, but communication is nonexistent from them. Escalation?
• Util2 threw a wobbler on Friday and is very unhappy. I will open a ticket with Dell. I'll probably have to go in and poke at it to troubleshoot.
• Related--the util2 failure revealed some missed DNS server configs; most if not all of those are now resolved.
• Tucson Synology SSD oops. I couldn't find an exact model match so I got a different brand. Turns out SSDs are still variable in actual capacity despite being labeled "X TB". I thought we were past that but apparently not. Cindy will return it and I'll get a new one.
• New Synology buy
• Obs1 went odd, restarted Xwindows which solved most of the issue but ended up needing a reboot to get audio back.
• Rm507-1 had a video failure with all screens flashing on and off. Hard reboot fixed. Probably video driver issue?
• Monitor.mountain DB error, rebooted.

GE

• Last week
  • Digging through the 550,000 lines of code of the LUCI system.
  • Discussion with Dave Thompson regarding the unstable amplifier 2 in LUCI2 (IT 6818). It appears we may need a more sophisticated solution than the current fixed value multiplier.
  • More discussion of LUCI FITS headers, stale DD values, and AO.
    • The AO team was informed that they need to be responsible for keeping DD values up to date.
  • Fixed the LUCI simulation configuration on osa-luci.
  • Finally, after more effort than expected, ran Aladin 11 on all the simulators. Unfortunately, it does not behave appreciably better than Aladin 10.
    • I also ran Aladin 10 and 11 separately from the RTD, and did not find any of the problems when running commands manually.
    • I now have pages and pages of exception stack traces to look at in order to fix the RTD/Aladin problems. One issue may be that the RMI server listeners call Aladin directly with commands.
• This week
  • Digging through the 550,000 lines of code of the LUCI system.
  • Evaluate whether we should consider moving to DS9. After running DS9 in my simulation, it has much better performance than Aladin, but may not have all the features we need.
  • Continue working on the RTD issues.

SH

• Vacation
• DNS bounce, DNS things

next:

• IT spending
• obs computer stuff from meeting
• monitor.mountain issues
• Mark computer stuff tomorrow, Steward visit tomorrow.

BM

• Last week:
  • LBTI engineering night. Had some issues with the install, auxloops not installed. Conf/calib missing files
  • Proposed code deployment changes to AO group. Will go for it this week.
  • Merged latest changes (gain ramp, Python formatting, GCC warning tweaks), still need to be tested.
  • Met with Gustavo, Alessandro. Got the details on the OCAM lab test setup. Might see if EngPanel can be run from virtualbox on spare-soul-wfs so we don't need the laptop.
  • Looked over HouseKeeper, DiagnApps.
• In the queue:
  • HouseKeeper logging during SwitchBCU timeout. Know what I need to do, just need to implement it.
  • Carefully make ao-supervisor installs consistent.
  • AO data for LUCI.

XZ

• Last week
  • DX ASM data analysis with last week test in the clean room with Guido
  • DX ASM data analysis with past shell rested telemetry with Guido
  • DX ASM data documentation with Guido
  • OCAM lab test setup, AO SW/plan, wind speed/TSS issues, etc
• This week
  • DX ASM path trade-off study with Guido
  • Fault recovery dicusstion/implemention with Guido and Arcetri
  • AO support

PSG

• Last week:
  • Testing swing arms for ARGOS. No issues, The problem we saw last time did not re-occur.
  • Worked through GUI display of status. Display issues are fixed now as well.
• This week:
  • Make change to HL2000 permananent (more than 1 connections).
  • Test to ensure it works.
