      Various possible topics
      • Update on DAPHNE readout recent progress, bug fix [Wes, Roland]
        • see slides from Wes
      • Update on CRT readout recent progress [Matt M, Wes, Roland]
        • Matt reports that a change to the order of configuring and starting has helped improved the stability of the system (confusion with how things are done for running stand-alone)
        • crash in ReadoutApp (segfault within Folly queue). Switching to MPMC queue helps.
      • Update on introducing callbacks for the TPs to TPHandler modules? [Roland and Alex]
        • this includes discussions about improvements in a couple of areas.
        • Giovanna mentioned that in the v5 line, the refactored data handling code handles all situations well, except for high-rate out-of-order data, such as TPs being sent from DLHs to the TP_DLH. And, of course, this remaining area is a focus of current discussion.
      • Ken Herner's request to add "Z" to the timestamp in our data filenames (do we understand this correctly?) [Wes, Kurt, all]
        • currently:
          • np04hd_raw_run028109_0033_dataflow5_datawriter_0_20240723T162203.hdf5
          • ATTRIBUTE "creation_timestamp" ... "1721751723576" (Tuesday, July 23, 2024 4:22:03.576 PM GMT)
          • ISO time converter is used (always GMT) as shown here
      • Updates on the front-end datatypes spreadsheet?
        • Roland will provide updates to it...
      • Short update on ICEBERG DAPHNE readout [Ron, Kurt]
        • turning off emulation_mode helped
