# Status of Issues on Github
- Roland downloaded a new updated version of the Issues, Zach will work based on that. - He plans to start a new transfer today. The bot idea for creating the issues remains. - He improved the header of the port. Bitbucket nuked the old tickets page, so we obv. can't link back to it. - Steve and Zach think that Monday next week we should see a functioning issue tracker. - Deborah makes a point that our webpage still points to the old Bitbucket issues page.
# Accumulated updates after release
- CarpetX and AMReX updates: No Roland today. - McLachlan: Peter is ready to run another test, but ran out of allocation in a machine he wanted to run. He's sorting it out with Steve (It's an LSU machine) - Zach gave an update on the Baikal family. He reports that, after doing a lot of BBH simulations, he learned that the way he did constraint enforcement in Baikal was not optimal. He comments that enforcing the algebraic constraints exponentially was bad. Doing the "standard" algebraic enforcement improved stability. As a follow up, Lucas asked if this historical wisdom of what to do on BSSN came from paper or experimentation. Zach mentions that things were done mostly empirically, with strong mathematical hints of the proper directions to take. - Deborah, in another follow up, notes that in changing from BSSNKai to McLachlan, she noticed that the MAYA waves code changes the shift condition depending on the mass ratios involved. She asks if we have compatible options in McLachlan. Peter says we have radially varying eta, but no tracking the the small and large BHs when q >> 1 to adjust it accordingly.
# Unanswered questions
- Please fill out the poll for new time - "Issues configuring SimFactory for PBS cluster (Hubble) - Jobs (MAKINO Taiki)": We've been backing and forthing with Maiko, assisting him in understanding simfactory behaviour and getting configuration files for his machine. Steve and Bayhan are the candidates to answer that and they are doing so.
