= Attendees =

* Elaine, Greg, Eric, TomG, Scooter (via Zoom)

= Agenda =
* ChimeraX registration
* ChimeraX 0.6 performance
* Review milestone priorities
* Wildcard/regex/case matching in commands

= Discussion =
* ChimeraX registration code ''almost'' works, Conrad will look into it
* ChimeraX 0.6 performance
 - Looking up bfactor (1 million times):
   - ChimeraX:
     - ctypes: 1.38s
     - custom library with property wrapping: 0.5s
     - custom library with no wrapping: 0.185s
     - random floating point attribute in Python: 0.072s
     - '''Cython with no wrapping: 0.021s'''
       - loop is in Cython
     - '''Cython with no wrapping: 0.156s'''
       - loop is in Python
   - Chimera 1:
     - access bfactor via wrappy2: 0.062s
     - '''custom library with no wrapping: 0.181s'''
 - Collect data
   - Cython is really fast
 - Paths forward
   - Cythonize Atom into Python type? method: '''0.098s'''; property: '''0.119s'''
   - Cythonize Atom methods? function: '''0.074s'''; method: '''0.204s'''; prop: '''0.135'''
   - Cythonize hydrogen bond code?  How hard is this?

= Action Items =
* ~~Conrad will enable registration code
* Eric will investigate Cython for classes and methods
* Conrad will write bundle code tutorial
* Conrad will continue working on ribbon tickets
* Conrad will create ticket to investigate implementing the "like" operator
 - e.g., to specify polymer in atomspec
