2. Online activities All of Online personnel observe Cleanroom operations
Everyone attends the 3:15 meeting
Learning about non-reported problems
Trying to find ways to reduce Operator Error
Beyond 2 towers
Housekeeping multi-pen strip chart GUI
Parallelizing INT scripts
Trying to move some LATTE 5 features into production earlier (e.g., HSK, LATc)
More design work on LCI method of test script structure
E-logbook
Brian requested ability to search shift logbook
Quickly provided with Google Desktop
Stand-alone e-logbook issue?
Implementing requested improvements

3. Online progress LATTE 4.9.0 CCB JIRA number 34
GPIB support for Agilent power supply (Brian)
RS-485 support for BPU Simpson meters (Brian)
FSW multi-tower PIG bug (Lester)
FSW PIG behavior provides source of OE for Testers
ACD (ancient) GASU problem (Jim provided work-around and a fix for LATTE)
LTE-254: SW verification passes, but in elog, the SW shows red. Fix this inconsistency (Brian)
LTE-251: If rcReport generation fails, wrong rcReport line is extracted from rcReport.out during export
LTE-257: Message logger does not launch
More?

4. Online progress LATTE 5 Exposing VSC interface to Python
Trying to pin down the core architecture
Having difficulty compiling combined LATTE & FSW in any Windows environment
Visual Studio
CygWin
MinGW
Jim: “It doesn’t look good.” Still some wiggle room, but he’s discouraged
Move to Linux?
Build with multiple compilers and tie EXEs together with network code (cumbersome, performance hit, extra work and maintenance)
